I am facing a strange problem with the combobox in Flex. In the following code :
public function rollCombo(cmb:ComboBox,value:String):void
{
if(value=='') return;
var i:int=0;
cmb.selectedIndex = 0;
var dp1:XMLListCollection = (XMLListCollection(cmb.dataProvider);
trace(value);
while(dp1[i]!=value && i<dp1.length)
cmb.selectedIndex = ++i;
cmb.validateNow();
cmb.validateDisplayList();
trace(cmb.selectedLabel);
}
in an example case, at the end of the execution of the function, i is 7, and
cmb.selectedLabel is "xyz"(according to the trace output), but the label displayed
in the combobox is a different one.
Also, this is rather unpredictable. It happens sometimes and not always.
The last selectedIndex is out of range, because you use pre-incrementation. Which means i becomes dp1.length before the test, and it's assigned to selectedIndex too. That might explain the weird behavior. You'll probably want to use post-incrementation.
Also. The only thing that gets executed in that while looks to be
cmb.selectedIndex = ++i;
I don't know if that's what you wanted, but you might need some "{}" there.

heres the code
var _obj;
if (instance_exists(obj_text)) _obj = obj_txt_queued; else _obj = obj_text;
with (instance_create_layer(0, 0, "text_layer", _obj))
{
msg = argument[0];
if (instance_exists(other)) originInstance = other.id else originInstance = noone;
if (argument_count > 1) background = argument[1]; else background = 1;
}
with (obj_phae)
{ if (state != scr_player_state_lock)
{
lastState = state;
state = scr_player_state_lock;
}
}
[layers](https://i.stack.imgur.com/9u9tD.png)
I tried removing any extra rooms that were not needed and I tried changing the layer name to something else.
I also tried using var instance_create_layer() but that obviously didn't work
I'm a bit confused at this part:
with (instance_create_layer(0, 0, "text_layer", _obj))
Especially the with(), as that function will go through every object in the room if it sees an object within the parameter, since you suggested to create a new object with it, I'm surprised it doesn't create an infinite loop. Maybe it works, I've never tried it myself, but I think there's a more logical way to assign variables from one object to a newly created object.
Assuming you want to use the With() statement to address the variables within the _obj, I think you can manage something similair through this function:
var object = instance_create_layer(0, 0, "text_layer", _obj)
object.msg = argument[0];
object.originInstance = id
if (argument_count > 1) object.background = argument[1]; else object.background = 1;
It's probably a given at this point, but double-check that this part of code can only run if it's in the same room that has a layer called "text_layer"
In the worst case, you may also try out instance_create_depth() and use the build-in depth variable from the object instead of the layer names. Using depth is more flexible, but less organised than layers.
After adding logic about creating price for object in grid it's always created "one line more" which is empty.
So, if there is need to be created two lines, it will be created 3 lines and that one addition will be empty.
Is there something what I missing in code?

The code looks like it only updates/inserts without creating a blank line.
From your attribute, you are using a Command Button (see here), which may have an associated command, such as New, which effectively pushes Ctrl+N, and would explain why you have a blank line.
The simplest way to check is just create a regular Button and override the clicked method, then copy/paste your code and push both buttons and see if they have different behavior.
Check the Command property on the button and see if there's something there. Try commenting out the super(); call.
You should perhaps consider just a Button or a Menu Item Button with an associated object.
in Flex I have something like that:
var dg:DataGrid = new DataGrid();
if (something) dg = dg1 else if (something_2) dg = dg2;
dg.dataProvider.getItemAt(3).id;
and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).
Why?
How can I pass dg1 or dg2 to dg?
Here is pasted almost full code of this part of application. I edited it to make that more clear.
var dg:DataGrid = null;
if ( currentState == "state1" ) { //if this condition is true then app. go into if and
dg = dataGrid_first; // make dg = DataGrid (1)
test.text = "inco"; // shows "inco" in "test" label
} else if ( currentState == "state2" ) { // if this is true then app. go..
dg = dataGrid_second; //here and set dg as DataGrid (exactly!) (2)
test.text = "outgo"; // and change test label into blank text (earlier text disapears)
}
search(dg);
It is modified with advice of '#splash'
Still not working.
EDIT:
I made this sceond edit to answer for all You who are helping me with that :) I think that it will be the best way. In codeblock above I added comments. (please read now comments and after that come back here :) )
Now I will explain exactly what happens.
I debug it many times and here are results:
dg is pointing at DataGrid (as component in flex, not as my dataGrid_first), I needed to extend DataGrid so now it is ColorColumn component (I don't know if I called it properly), not DataGrid. And dg is pointing at ColorColumn not at dataGrid_first or dataGrid_second. I even tried today the same thing what suggest #splash:
if ( currentState == "state1" ) {
test.text = "inco";
search(dataGrid_first);
} else if ( currentState == "state2" ) {
test.text = "outgo";
search(dataGrid_second);
}
and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state. If You have other ideas how I can do that in right way then I will pleased to hear about it. :)
But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.
If dg is never pointing to dg1 and dg2 then your (something) expressions may be evaluate to false. Check the value of your if-conditions - this should be easy to debug.
This should work:
var dg:DataGrid = null;
if (something)
dg = dg1;
else if (something_2)
dg = dg2;
if (dg)
{
// do something with dg
}
[Update]
I still can't see why your code isn't working, but you could simplify it like this:
if ( currentState == "state1" ) {
test.text = "inco";
search(dataGrid_first);
} else if ( currentState == "state2" ) {
test.text = "outgo";
search(dataGrid_second);
}
I'd propose to write this - since I guess either dg1 or dg2 should be assigned:
if (something) {
dg = dg1;
} else {
dg = dg2;
}
There may be cases, where if () {} else () {} neither executes the first or the second conditional block.
Finally a small hint, which structurally eliminates unwanted assignments in if conditions: Always write the literal left of the comparison operation: if ( "state1" == currentState ). If you accidentally typed = instead of ==, the flex compiler emits an error. The other notation silently assigns a value.
Additionally: Did you single-stepped through your code and watched the variables dg1, dg2 and dg? If not, set a breakpoint a few line before the if-statement and run the code step by step from there on. What do you see?
Here's a another tip: Use assertions to check for inconistencies:
package my.company.utilities {
public function assert(expression:Boolean):void {
// probably conditionally compile this statement
if (!expression) {
throw new Error("Assertion failed!");
}
} // assert
}
Use it e.g. at the beginning of a method like this:
public function doTransaction( fromAccount:int, toAccount:int ) {
assert( 0 < fromAccount );
assert( 0 < toAccount );
}
A typically good use of assert is to check variables regarding their range. As of the above example, fromAccount and toAccount should always be positive. Due to a bug, bad values might get passed to doTransaction(). In this case, the assertion fires an error.
When the first cell of an excel sheet to import using ExcelStorage.ExtractRecords is empty, the process fail. Ie. If the data starts at col 1, row 2, if the cell (2,1) has an empty value, the method fails.
Does anybody know how to work-around this? I've tried adding a FieldNullValue attribute to the mapping class with no luck.
Here is a sample project that show the code with problems
Hope somebody can help me or point in some direction.
Thank you!
It looks like you have stumbled upon an issue in FileHelpers.
What is happening is that the ExcelStorage.ExtractRecords method uses an empty cell check to see if it has reached the end of the sheet. This can be seen in the ExcelStorage.cs source code:
while (CellAsString(cRow, mStartColumn) != String.Empty)
{
try
{
recordNumber++;
Notify(mNotifyHandler, mProgressMode, recordNumber, -1);
colValues = RowValues(cRow, mStartColumn, RecordFieldCount);
object record = ValuesToRecord(colValues);
res.Add(record);
}
catch (Exception ex)
{
// Code removed for this example
}
}
So if the start column of any row is empty then it assumes that the file is done.
Some options to get around this:
Don't put any empty cells in the first column position.
Don't use excel as your file format -- convert to CSV first.
See if you can get a patch from the developer or patch the source yourself.
The first two are workarounds (and not really good ones). The third option might be the best but what is the end of file condition? Probably an entire row that is empty would be a good enough check (but even that might not work in all cases all of the time).
Thanks to the help of Tuzo, I could figure out a way of working this around.
I added a method to ExcelStorage class to change the while end condition. Instead of looking at the first cell for empty value, I look at all cells in the current row to be empty. If that's the case, return false to the while. This is the change to the while part of ExtractRecords:
while (!IsEof(cRow, mStartColumn, RecordFieldCount))
instead of
while (CellAsString(cRow, mStartColumn) != String.Empty)
IsEof is a method to check the whole row to be empty:
private bool IsEof(int row, int startCol, int numberOfCols)
{
bool isEmpty = true;
string cellValue = string.Empty;
for (int i = startCol; i <= numberOfCols; i++)
{
cellValue = CellAsString(row, i);
if (cellValue != string.Empty)
{
isEmpty = false;
break;
}
}
return isEmpty;
}
Of course if the user leaves an empty row between two data rows the rows after that one will not be processed, but I think is a good thing to keep working on this.
Thanks
I needed to be able to skip blank lines, so I've added the following code to the FileHelpers library. I've taken Sebastian's IsEof code and renamed the method to IsRowEmpty and changed the loop in ExtractRecords from ...
while (CellAsString(cRow, mStartColumn) != String.Empty)
to ...
while (!IsRowEmpty(cRow, mStartColumn, RecordFieldCount) || !IsRowEmpty(cRow+1, mStartColumn, RecordFieldCount))
I then changed this ...
colValues = RowValues(cRow, mStartColumn, RecordFieldCount);
object record = ValuesToRecord(colValues);
res.Add(record);
to this ...
bool addRow = true;
if (Attribute.GetCustomAttribute(RecordType, typeof(IgnoreEmptyLinesAttribute)) != null && IsRowEmpty(cRow, mStartColumn, RecordFieldCount))
{
addRow = false;
}
if (addRow)
{
colValues = RowValues(cRow, mStartColumn, RecordFieldCount);
object record = ValuesToRecord(colValues);
res.Add(record);
}
What this gives me is the ability to skip single empty rows. The file will be read until two successive empty rows are found
I've ran into a weird problem with getCharBoundaries, I could not figure out what coordinate space the coordinates returned from the function was in. What ever I tried I could not get it to match up with what I expected.
So I made a new project and and added simple code to highlight the last charater in a textfield, and all of a sudden it worked fine. I then tried to copy over the TextField that had been causing me problems, into the new project. And now the same weird offset appeared 50px on the x axis. Everything else was spot on.
So after some headscracthing comparing the two TextFields, I simply can not see a difference in their properties or transformation.
So I was hoping that someone might now what property might affect the coordinates returned by getCharBoundaries.
I am using Flash CS4.
I've just had exactly the same problem and thought I'd help out by offering what my findings are. With a help from this thread, I tried to find everything that wasn't 'default' about the textfield I was using. I found that when I had switched my TextFormatAlign (or 'align' in the IDE) and TextFieldAutoSize properties to 'LEFT' as opposed to 'CENTER', it solved the problem.
A little late in the game perhaps, but worth knowing for anyone running into the same problem. This was the only thread I could find that raised the right flag...
Well the getCharBoundaries returns the boundaries in the textfield coordinate system. Where the origin is topleft corner of the textfield.
getCharBoundaries does not take into consideration the scrolling. you need to check if there are scrollbars on its parent (textarea) and if so relocate. One quick way of doing it is using localtoglobal and globaltolocal. Use the first to translate from the textfield coordinate system to the application coordinate system and then use the second to translate from the app coordinate system to the coordinate system of the parent of the textfield which is the textarea. I'm fine tuning a my method to get char boundaries i will publish it today on my blog

To literally answer your question, it returns the coordinates in the TextField's coordinate system, not it's parent, and it is affected by DisplayObject.transform.matrix, which is the backing for the .x, .y, .scaleX, .scaleY, .width, .height, and .rotation properties.
What ever it was the solution was simple to add a new TextField, never found out what property screwed everything up.
The first answer is correct in most cases. However if your field is parented to another movie clip it may still return the wrong y coordinate. try this code:
//if this doesn't work:
myTextFormat = new TextFormat();
myTextFormat.align = TextFormatAlign.LEFT;
myFieldsParent.myField.autoSize = TextFieldAutoSize.LEFT;
myFieldsParent.myField.setTextFormat( myTextFormat);
//try this:
var x = myFieldsParent.myField.getCharBoundaries(o).x;
var y = myFieldsParent.myField.getCharBoundaries(o).y;
var myPoint:Point = new Point(myField.getCharBoundaries(o).x,myField.getCharBoundaries(o).y);
var pt:Point = new Point(myFieldsParent.myField.getCharBoundaries(o).x, myFieldsParent.myField.getCharBoundaries(o).y);
pt = myFieldsParent.myField.localToGlobal(pt);
//pt is the variable containing the coordinates of the char in the stage's coordinate space. You may still need to offset it with a fixed value but it should be constant.
I didn't test this code as I have adapted this example from code that is embedded into my project so I apologize if I'm missing something...
