I'm using ClosedXML library to generate a simple Excel file with 2 worksheets.
I keep getting error message whenever i try to open the file saying
"We found a problem with some content in "example.xlsx". Do you want us to try to recover as much as we can. if you trust source of this workbook, click Yes"
If i click Yes, it displays the data as expected, i don't see any
problems with it. Also if i generate only 1 worksheet this error does
not appear.
This is what my stored procedure returns, first result set is populated in sheet1 and second result set is populated in sheet2, which works as expected.
Workbook data
Here is the method i am using, it returns 2 result sets and populates both result sets in 2 different worksheets:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult POAReport(POAReportVM model)
{
POAReportVM poaReportVM = reportService.GetPOAReport(model);
using (var workbook = new XLWorkbook())
{
IXLWorksheet worksheet1 = workbook.Worksheets.Add("ProductOrderAccuracy");
worksheet1.Cell("A1").Value = "DATE";
worksheet1.Cell("B1").Value = "ORDER";
worksheet1.Cell("C1").Value = "";
var countsheet1 = 2;
for (int i = 0; i < poaReportVM.productOrderAccuracyList.Count; i++)
{
worksheet1.Cell(countsheet1, 1).Value = poaReportVM.productOrderAccuracyList[i].CompletedDate.ToString();
worksheet1.Cell(countsheet1, 2).Value = poaReportVM.productOrderAccuracyList[i].WebOrderID.ToString();
worksheet1.Cell(countsheet1, 3).Value = poaReportVM.productOrderAccuracyList[i].CompletedIndicator;
countsheet1++;
}
IXLWorksheet worksheet2 = workbook.Worksheets.Add("Summary");
worksheet2.Cell("A1").Value = "Total Orders Sampled";
worksheet2.Cell("B1").Value = "Passed";
worksheet2.Cell("C1").Value = "% Passed";
worksheet2.Cell(2, 1).Value = poaReportVM.summaryVM.TotalOrdersSampled.ToString();
worksheet2.Cell(2, 2).Value = poaReportVM.summaryVM.Passed.ToString();
worksheet2.Cell(2, 3).Value = poaReportVM.summaryVM.PassedPercentage.ToString();
//save file to memory stream and return it as byte array
using (var ms = new MemoryStream())
{
workbook.SaveAs(ms);
ms.Position = 0;
var content = ms.ToArray();
return File(content, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
}
}
}
I had similar problem. For me the cause was as mentioned in this answer:
I had this issue when I was using EPPlus to customise an existing template. For me the issue was in the template itself as it contained invalid references to lookup tables. I found this in Formula -> Name Manager.
You may find other solutions there.
Apologies as my reputation is too low to add a comment.
I was just wondering if it's possible to return a single row using Npgsql in a .Net Core Script.
I've been doing with the Read Method like bellow
NpgsqlCommand command = new NpgsqlCommand (
" select col01, col02, col03 from table ",
dbconnection
);
var result = command.ExecuteReader();
while(result.Read()) {
var varCol01 = result["col01"];
var varCol02 = result["col02"];
}
Which seems a bit excessive for a single row because I would have to exit the while manually.
Each time you call NpgsqlDataReader.Read, you're reading an additional row - so your code sample doesn't seem to be a good fit for a single row scenario...
If you know you're only getting a single row, why not do something along the lines of:
var reader = command.ExecuteReader();
reader.Read(); // You can do a Debug.Assert to make sure the result of this is true
var (col1, col2) = (result["col01"], result["col02"]);
So this works but it takes 15 seconds for a spreadsheet with 60 items.
function addToModel(name,birth,age){
var newRecord = app.models.ImportData.newRecord();
newRecord['PRESIDENT'] = name;
newRecord['BIRTH_PLACE'] = birth;
newRecord['AGE_ELECTED'] = age;
app.saveRecords([newRecord]);
}
function getSpreadsheet(){
var sh = SpreadsheetApp.openById("zzz");
var ss = sh.getSheetByName("Sheet1");
var data = ss.getDataRange().getValues();
THIS WAS WAY ONE, TAKES 15 SECONDS
for (var i=1; i<data.length;i++)
{
addToModel(data[i][1],data[i][2],data[i][3].toString());
}//for loop
}
but I noticed that the command is saveRecordS not saveRecord and with anything in google apps script, the fewer calls the better, so I tried this but it doesn't work
//SAME SPREADSHEET INFO
var result = [];
for (var i=0; i<data.length;i++)
{
var newRecord = app.models.ImportData.newRecord();
newRecord['PRESIDENT'] = data[i][1];
newRecord['BIRTH_PLACE'] = data[i][2];
newRecord['AGE_ELECTED'] = data[i][3].toString();
result.push(newRecord);
}//for loop
app.saveRecords([result]);
Expected result: new records in my table, much faster than the first version. Actual result: "Cannot read property "key" from undefined" which is triggered from the last line (saveRecords). I tried both app.saveRecords(result) and ([result]), same problem both times.
Note: this example is from an appmaker university tutorial that no longer works because of the changes for appmaker v2.
I think that it's model.newRecord() takes time for each new item created, while time on app.saveRecords() is ignorable.
Could you please confirm that you are EU user? as we EU user are facing same issue (link) due to the server location, if it is the case, please help star that issue and give more info to help Google solve that issue. Thanks.

I get this error on a comment, not an actual if statement, I can't bypass this without commenting out Data_Load(), which is what loads the users' data.
I recently updated to version 1.4.1567, maybe that is a bug in this version.

GM's compiler is always weird about those line errors. It often doesn't count blank lines as actual lines.
If you adjust for that issue, the real line of code that is throwing the error is this:
if (ForceResets != Force_Resets) {
Maybe it doesn't like that you're basically asking "If something is not equal to itself", which hardly makes sense. That statement will always evaluate to false, so you should probably remove it.
Seeing as you don't declare var on any of these variables, then you're manipulating the variables on the instance that called this script. If there's somehow a ForceResets script variable, and a ForceResets variable on the calling instance, then this whole thing might be a naming issue. I'm also making this assuming because you called:
ForceResets = ini_read_string("External","Force_Resets",Force_Resets);
Where that third parameter isn't declared anywhere in this script.
All in all, I'd say that you need to clean this script up a little.
Pro Tip: Use for(var i = 0; ... instead of for(i = 0 99% of the time. Otherwise you're leaving this instance with an i variable that it will never use.
I have an asp.net application, and if there is an exception in the code I catch it log some details (the stack trace, exception details etc) to a database and return a reference code to the client.
I noticed that the ASP.Net yellow screen of death shows a few lines of code around the offending line as well as the stack trace.
I want to log that "Source Error:" too. Where and how does the ASP.net get the "Source Error:" source code from?
Edit: If you want the file name and line number of the error, you can get it this way:
var exc = Server.GetLastError();
var frame = new StackTrace(exc, true).GetFrame(0);
var sourceFile = frame.GetFileName();
var lineNumber = frame.GetFileLineNumber();
// sourceFile = c:\path\to\source\file.aspx
// lineNumber = 123
Reference: How does ASP.NET get line numbers in it's generic error handler
It looks like the code in the .NET framework responsible for getting source information is System.Web.FormatterWithFileInfo.GetSourceFileLines().
...
for (int i=1; ; i++) {
// Get the current line from the source file
string sourceLine = reader.ReadLine();
if (sourceLine == null)
break;
// If it's the error line, make it red
if (i == lineNumber)
sb.Append("<font color=red>");
// Is it in the range we want to display
if (i >= lineNumber-errorRange && i <= lineNumber+errorRange) {
fFoundLine = true;
String linestr = i.ToString("G", CultureInfo.CurrentCulture);
sb.Append(SR.GetString(SR.WithFile_Line_Num, linestr));
if (linestr.Length < 3)
sb.Append(' ', 3 - linestr.Length);
sb.Append(HttpUtility.HtmlEncode(sourceLine));
if (i != lineNumber+errorRange)
sb.Append("\r\n");
}
if (i == lineNumber)
sb.Append("</font>");
if (i>lineNumber+errorRange)
break;
}
...
Basically it does nothing more than open the source file, and find the line referenced by lineNumber in the error, along with 2 lines before and after.
