I want to ask why my Text Area produce the text 'undefined'
mdm.Database.MySQL.connect("localhost", "3306", true, "root", "adaptasi");
mdm.Database.MySQL.runQuery("SELECT morfo FROM materi");
TextIsi1.text = mdm.Database.MySQL.getData();
I use mdm for my flash (swf) project that connect with database.
Returns
An Array
Description
Returns the full query data to a 2 dimensional array. The first dimension contains the row number and the second dimension contains the field number.
Notes
A Query must first be executed with mdm.Database.MySQL.runQuery()
Example Code
//Prompts the data in Row 1, Field 4:
mdm.Database.MySQL.runQuery("SELECT * FROM mytable")
var dataSet:Array = mdm.Database.MySQL.getData();
mdm.Dialogs.prompt(dataSet[0][3])
//This example will display the entire contents of the specified table in a dialog prompt
var tableName:String = "myTable";
mdm.Database.MySQL.runQuery("SELECT * FROM "+tableName)
var dataSet:Array = mdm.Database.MySQL.getData();
var myText = ""
for (i=0; i<dataSet.length; i++) {
for (n=0; n<dataSet[0].length; n++) {
myText += "FIELD"+(n+1)+" = "+dataSet[i][n]+", ";
}
myText += "\n";
}
mdm.Dialogs.prompt(myText);
from documentation
your code should be something like:
TextIsi1.text = mdm.Database.MySQL.getData()[0][0];

I want to create multiple records at the same time using client script. This is what I'm doing:
var ceateDatasource = app.datasources.Reservation.modes.create;
var newItem = ceateDatasource.item;
newItem.User = user; //'eric'
newItem.Description = description; //'000'
newItem.Location_Lab_fk = lab.value.Id; //'T'
newItem.Area_fk = area.value.Id; //'L'
newItem.Equipment_fk = equipment.value.Id; //'S'
for(var i = 0 ; i < 3; i ++) {
newItem.Start_Date = startDate;
newItem.Start_Hours = '03';
newItem.Start_Minutes = '00';
newItem.End_Date = startDate;
newItem.End_Hours = '23';
newItem.End_Minutes = '30';
// Create the new item
ceateDatasource.createItem();
}
But the result I'm getting is this one:
The three records are created but the only the first one has data. The other two records have empty values on their fields. How can I achieve this?
Thanks.
Update(2019-3-27):
I was able to make it work by putting everything inside the for loop block. However, I have another question.
Is there any method like the below sample code?
var recordData = [Data1, Data2, Data3]
var ceateDatasource;
var newItem = new Array(recordData.length) ;
for(var i = 0 ; i < recordData.length; i ++) {
ceateDatasource = app.datasources.Reservation.modes.create;
newItem[i] = ceateDatasource.item;
newItem[i].User = recordData[i].user;
newItem[i].Description = recordData[i].Description;
newItem[i].Location_Lab_fk = recordData[i].Location_Lab_fk;
newItem[i].Area_fk = recordData[i].Area_fk;
newItem[i].Equipment_fk = recordData[i].Equipment_fk;
newItem[i].Start_Date = recordData[i].Start_Date;
newItem[i].Start_Hours = recordData[i].Start_Hours;
newItem[i].Start_Minutes = recordData[i].Start_Minutes;
newItem[i].End_Date = recordData[i].End_Date;
newItem[i].End_Hours = recordData[i].End_Hours;
newItem[i].End_Minutes = recordData[i].End_Minutes;
}
// Create the new item
ceateDatasource.createItem();
First, it prepares an array 'newItem' and only calls 'ceateDatasource.createItem()' one time to save all new records(or items).
I try to use this method, but it only saves the last record 'newItem[3]'.
I need to write a callback function in 'ceateDatasource.createItem()' but Google App Maker always show a warning "Don't make functions within a loop". So, are there any methods to call 'createItem()' one time to save several records? Or are there some functions like 'array.push' which can be used?
Thanks.
As per AppMaker's official documentation:
A create datasource is a datasource used to create items in a particular data source. Its item property is always populated by a draft item which can be bound to or set programmatically.
What you are trying to do is create three items off the same draft item. That why you see the result you get. If you want to create multiple items, you need to create a draft item for each one, hence all you need to do is put all your code inside the for loop.
for(var i = 0 ; i < 3; i ++) {
var ceateDatasource = app.datasources.Reservation.modes.create;
var newItem = ceateDatasource.item;
newItem.User = user; //'eric'
newItem.Description = description; //'000'
newItem.Location_Lab_fk = lab.value.Id; //'T'
newItem.Area_fk = area.value.Id; //'L'
newItem.Equipment_fk = equipment.value.Id; //'S'
newItem.Start_Date = startDate;
newItem.Start_Hours = '03';
newItem.Start_Minutes = '00';
newItem.End_Date = startDate;
newItem.End_Hours = '23';
newItem.End_Minutes = '30';
// Create the new item
ceateDatasource.createItem();
}
If you want to save several records at the same time using client script, then what you are looking for is the Manual Save Mode. So all you have to do is go to your model's datasource and click on the checkbox "Manual Save Mode".
Then use the same code as above. The only difference is that in order to persist the changes to the server, you need to explicitly save changes. So all you have to do is add the following after the for loop block:
app.datasources.Reservation.saveChanges(function(){
//TODO: Callback handler
});
I'm new to Java scripting and Google Apps Scripts so i am sorry if this has already been answered. I was not able to find what i was looking for over the last few months of working on this project.
I am working on a variant of the scripts here:
Delete row in Google Sheets if certain "word" is found in cell
AND
Google Sheet Script - Find Value in Col and Delete Row
I want to create a button, or menu, that will allow someone to enter specific data, and have each row in the spreadsheet containing that data deleted.
I have a test sheet here that illustrates the data i'm working with, formulas i'm using, and has the beginning of the script attached to it:
https://docs.google.com/spreadsheets/d/1e2ILQYf8MJD3mrmUeFQyET6lOLYEb-4coDTd52QBWtU/edit?usp=sharing
The first 4 sheets are pulling data from the "Form Responses 1" sheet via a formula in cell A:3 in each sheet so the data would only need to be deleted from the "Form Responses 1" sheet to clear it from the rest of the sheets.
I tried working this in but i do not think i am on the right track.
https://developers.google.com/apps-script/guides/dialogs
I also posted this on Google Docs Help Forum 60 days ago, but have not received any responses.
Any help would be greatly appreciated.
There's a few steps. For usability of UI this takes a little longer code. In concise form:
The user activates a dialog and enters a string.
Rows w/ the string are deleted (with error handling and confirmation)
(Hopefully this gets you started and you can tailor it to your needs)
Function that initiates the menu:
function onOpen(){
SpreadsheetApp.getUi()
.createMenu('My Menu')
.addItem('Delete Data', 'deleteFunction')
.addToUi();
}
The main workhorse:
function deleteFunction(){
//declarations
var sheetName = "Form Responses 1";
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName(sheetName);
var dataRange = sheet.getDataRange();
var numRows = dataRange.getNumRows();
var values = dataRange.getValues();
var delete_string = getUIstring();//open initial UI, save value
if (delete_string.length < 3) return shortStringError()//UI to protect your document from an accidental entry of a very short string.
//removing the rows (start with i=2, so don't delete header row.)
var rowsDeleted = 0;
for (var i = 2; i <= numRows; i++){
var rowValues = values[i-1].toString();//your sheet has various data types, script can be improved here to allow deleting dates, ect.
if (rowValues.indexOf(delete_string) > -1){
sheet.deleteRow(i - rowsDeleted);//keeps loop and sheet in sync
rowsDeleted++;
}
}
postUIconfirm(rowsDeleted);//Open confirmation UI
}
Isolated UI functions to help make above function more concise:
function getUIstring(){
var ui = SpreadsheetApp.getUi();
var response = ui.prompt("Enter the target data element for deletion")
return response.getResponseText()
}
function postUIconfirm(rowsDeleted){
var ui = SpreadsheetApp.getUi();
ui.alert("Operation complete. There were "+rowsDeleted+" rows deleted.")
}
function shortStringError(){
var ui = SpreadsheetApp.getUi();
ui.alert("The string is too short. Enter a longer string to prevent unexpected deletion")
}
I'll just show a way to delete the cell value if it matches your search criteria. It's up to you to connect it to buttons ,etc.
You'll loop through a Sheet Range. When you find the word match, delete it using clearContent()
function deleteSpecificData() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];
var range = sheet.getRange("Sheet1!A1:C4");
var values = range.getValues();
var numArray = [1,2,3,4,5,6,7,8,9];
var deleteItem = "Garen";
Logger.log(range);
for(var i=0; i< values.length; i++){
for(var j=0; j<values[i].length; j++){
if(values[i][j] == deleteItem){
var row = numArray[i];
var col = numArray[j];
var range = sheet.getRange(row,col).clearContent();
}
}
}
}

I have a pdf file that as the follow security properties: printing: allowed; document assembly: NOT allowed; content copy: allowed; content copy for accessibility: allowed; page extraction:NOT allowed;
I try to get text with sample code as documentation sample as follow:
pdftext.Text = null;
StringBuilder text = new StringBuilder();
PdfReader pdfReader = new PdfReader(filename);
for (int page = 1; page <= pdfReader.NumberOfPages; page++)
{
ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy);
text.Append(System.Environment.NewLine);
text.Append("\n Page Number:" + page);
text.Append(System.Environment.NewLine);
currentText = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(currentText)));
text.Append(currentText);
progressBar1.Value++;
}
pdftext.Text += text.ToString();
pdfReader.Close();
but the output text is lines with ""??? ? ???????\n?? ??? ? " values;
seems that file is crypted or we have a encoding problem...
note that in the follow lines
var f = pdfReader.IsOpenedWithFullPermissions; -> FALSE
var f1 = pdfReader.IsEncrypted(); - > FALSE
var f2 = pdfReader.ComputeUserPassword(); - > NULL
var f3 = pdfReader.Is128Key(); - > FALSE
var f4 = pdfReader.HasUsageRights();
f, f1, f3, f4 return FALSE ...than seems that the document is not crypted,
...so I don't know if is a Encoding problem or question related to encrypet strings...
Someone can help me?
thanks in advance.

Whenever you have trouble extracting text from a document using standard code, the first thing to do is try and copy&paste the text from it using Adobe Acrobat Reader. Adobe Reader copy&paste implements text extraction according to the recommendations of the PDF specification, and if this fails, this usually means that the necessary information required for text extraction in the document are either missing or broken (by accident or by design). To extract the text, one either needs to customize the code specifically to the specific PDF or resort to OCR.
In case of the document at hand, Adobe Reader copy&paste does result in garbage, too, just like when extracting with iText. Thus, there is something fishy in the document.
Inspecting the document one finds that the fonts contain ToUnicode mappings like this:
/CIDInit /ProcSet
findresource begin 12 dict begin begincmap /CIDSystemInfo<</Registry(Adobe)
/Ordering(Identity)
/Supplement 0
>>

I.e., if you are not into this, the fonts claim that all their glyphs (with the exception of the space glyph at 0x20) represent characters U+E0xx from the Unicode private use area. As the name of that area indicates, there is no common meaning of characters with these values.
Thus, text extraction according to the PDF specification will return strings of characters with undefined meaning with results as you observed in iText or I saw in Adobe Reader.
Sometimes in such a situation one can still enforce proper text extraction by ignoring the ToUnicode map and using either the font Encoding or information inside the embedded font program.
Unfortunately it turns out that here the Encoding effectively contains the same information as does the ToUnicode map, e.g. for the same font as above
/Differences [ 32 /space /uniE0F9 /uniE0F1 /uniE0FA /uniE0F7 /uniE0A3 /uniE084 /uniE097 /uniE098
/uniE09A /uniE08A /uniE099 /uniE0A5 /uniE086 /uniE094 /uniE0DE /uniE0A6 /uniE096
/uniE088 /uniE082 /uniE04C /uniE0A4 /uniE0F6 /uniE0F2 /uniE0D8 /uniE0AA /uniE06C
/uniE087 /uniE095 /uniE0C4 /uniE07E /uniE055 /uniE089 /uniE085 /uniE083 /uniE070
/uniE0E6 /uniE080 /uniE0C8 /uniE0F4 /uniE062 /uniE0F3 /uniE04E /uniE05E ]
and the fonts turns out to be Type3 fonts, i.e. there is no embedded font program but each glyph is defined as an individual PDF canvas without further character information.
Thus, nothing to gain here either.
Actually these small PDF canvasses contain inlined bitmap graphics of the respective glyph which also is the cause of the poor graphical quality of the document (if you don't see that immediately, simply zoom in a bit and you'll see the ragged outlines of the glyphs).
By the way, such a construct usually means that the producer of the PDF explicitly wants to prevent text extraction.
If you happen to have to extract text from many such documents, you can try and determine a mapping from their U+E0xx characters to actually sensible Unicode characters and apply that mapping to your extracted text.
If all those fonts in all those documents happen to use the same U+E0xx codepoints for the same actual characters, you'll be able to do text extraction from those documents after investing a certain amount of initial work.
Otherwise do try OCR.
The following code adds pages to a document which map the ToUnicode values to the characters shown:
void AddFontsTo(PdfReader reader, PdfStamper stamper)
{
int documentPages = reader.NumberOfPages;
for (int page = 1; page <= documentPages; page++)
{
// ignore inherited resources for now
PdfDictionary pageResources = reader.GetPageResources(page);
if (pageResources == null)
continue;
PdfDictionary pageFonts = pageResources.GetAsDict(PdfName.FONT);
if (pageFonts == null || pageFonts.Size == 0)
continue;
List<BaseFont> fonts = new List<BaseFont>();
List<string> fontNames = new List<string>();
HashSet<char> chars = new HashSet<char>();
foreach (PdfName key in pageFonts.Keys)
{
PdfIndirectReference fontReference = pageFonts.GetAsIndirectObject(key);
if (fontReference == null)
continue;
DocumentFont font = (DocumentFont) BaseFont.CreateFont((PRIndirectReference)fontReference);
if (font == null)
continue;
PdfObject toUni = PdfReader.GetPdfObjectRelease(font.FontDictionary.Get(PdfName.TOUNICODE));
CMapToUnicode toUnicodeCmap = null;
if (toUni is PRStream)
{
try
{
byte[] touni = PdfReader.GetStreamBytes((PRStream)toUni);
CidLocationFromByte lb = new CidLocationFromByte(touni);
toUnicodeCmap = new CMapToUnicode();
CMapParserEx.ParseCid("", toUnicodeCmap, lb);
}
catch
{
toUnicodeCmap = null;
}
}
if (toUnicodeCmap == null)
continue;
ICollection<int> mapValues = toUnicodeCmap.CreateDirectMapping().Values;
if (mapValues.Count == 0)
continue;
fonts.Add(font);
fontNames.Add(key.ToString());
foreach (int value in mapValues)
chars.Add((char)value);
}
if (fonts.Count == 0 || chars.Count == 0)
continue;
Rectangle size = (fonts.Count > 10) ? PageSize.A4.Rotate() : PageSize.A4;
PdfPTable table = new PdfPTable(fonts.Count + 1);
table.AddCell("Page " + page);
foreach (String name in fontNames)
{
table.AddCell(name);
}
table.HeaderRows = 1;
float[] widths = new float[fonts.Count + 1];
widths[0] = 2;
for (int i = 1; i <= fonts.Count; i++)
widths[i] = 1;
table.SetWidths(widths);
table.WidthPercentage = 100;
List<char> charList = new List<char>(chars);
charList.Sort();
foreach (char character in charList)
{
table.AddCell(((int)character).ToString("X4"));
foreach (BaseFont font in fonts)
{
table.AddCell(new PdfPCell(new Phrase(character.ToString(), new Font(font))));
}
}
stamper.InsertPage(reader.NumberOfPages + 1, size);
ColumnText columnText = new ColumnText(stamper.GetUnderContent(reader.NumberOfPages));
columnText.AddElement(table);
columnText.SetSimpleColumn(size);
while ((ColumnText.NO_MORE_TEXT & columnText.Go(false)) == 0)
{
stamper.InsertPage(reader.NumberOfPages + 1, size);
columnText.Canvas = stamper.GetUnderContent(reader.NumberOfPages);
columnText.SetSimpleColumn(size);
}
}
}
I applied it to your document like this:
string input = #"4700198773.pdf";
string output = #"4700198773-fonts.pdf";
using (PdfReader reader = new PdfReader(input))
using (FileStream stream = new FileStream(output, FileMode.Create, FileAccess.Write))
using (PdfStamper stamper = new PdfStamper(reader, stream))
{
AddFontsTo(reader, stamper);
}
The additional pages look like this:
Now you have to compare the outputs for the different fonts and pages of this document with each other and with those of a representative selection of file. If you find good enough a pattern, you can try this replacement way.
I am having trouble with displaying the results in the search activity of my app. I wonder where it went wrong.
The aim of the function below is to search the input query of the user and find it in every files listed. But the results only matches one data eventhough the query is also present in the other files. Here is the code.
public void searchFiles(File[] filelist, String query, String querysearch, String[] namesOfFiles){
querysearch = "SELECT * FROM Data WHERE ObjectID = ? ";
int temp2 = filelist.length;
for (int i = (temp2-1); i >= 0; i--) {
if(!(filelist[i].getName().equals("DataObjectDB.db")) && !(filelist[i].getName().endsWith("-journal"))){
temp1 = filelist[i].getName();
namesOfFiles[i] = temp1.replaceAll(".db$", "");
Toast.makeText(getApplicationContext(),"Searching " + query + " in: " + namesOfFiles[i], Toast.LENGTH_SHORT).show();
DatabaseHelper db1 = new DatabaseHelper(getApplicationContext(),namesOfFiles[i]);
SQLiteDatabase sqldb = db1.getWritableDatabase();
cursor = sqldb.rawQuery(querysearch, new String[]{query});
Toast.makeText(getApplicationContext(),cursor.toString(), Toast.LENGTH_SHORT).show();
}
}
final ListView listView = (ListView) findViewById(R.id.results_listview);
SearchAdapter adapter = new SearchAdapter(this, R.layout.results_column, cursor,0 );
listView.setAdapter(adapter);
}
The searchFiles() function passes the filelist, query, querysearch and namesOfFiles where 1) filelist contains the list of files in the source folder 2) query is the user input he/she wants to search 3) querysearch is the select statement 3) namesofFiles is just an empty string.
I indicate a toast to see if the code traverses through all the folders. And yes it is. But I don't know why it is not displaying all the results.
Any help? Thanks!
Found an answer on different posts. Basically, you just have to use hashmap and arraylist first before setting up the adapter directly.
i have this code
MasterSoapClient sp = new MasterSoapClient();
MasterData[] lstMasterData = sp.GetActivityType(stid, null, 1);
grdEditActivityType.DataSource = lstMasterData;
grdEditActivityType.DataBind();
Session["opType"] = 2;
txtActivityCode.Text = lstMasterData.ToString();
txtActivityCode.DataBind();
here i called web service and put all data in this Gridview "grdEditActivityType "
and already workin
but there is column of lstMasterData i want to put it in the text box out of the grid
how i can do this ?
txtActivityCode.Text is a Property that you can use to assign a text value to the TextBox.
If you use txtActivity.Text = " some input "; Your textbox will contain the text " some input ".
You don't need to Bind txtActivityCode afterwards.
Having this clarified the next step is to create the string you want using to assign to the text box.
string s = "";
foreach( var masterData in lstMasterData )
{
s += masterData.SomeProperty; // s += masterData.ToString(); maybe, it depends on what do you want to put in the textbox;
}
txtActivityCode.Text = s;
And that's all.
I would suggest to start look more over ASP.NET tutorials to understand better how this framework works.
