Hello all,
I have a problem with formatting an Excel Range object in C# using Interop.Excel. Here is a snippet of the procedure:
private static bool FormatExcel(string filename, int font){
Excel.Application excelApp = new Excel.ApplicationClass();excelApp.DisplayAlerts = false;
try{
Excel.Workbook excelWkBook = excelApp.Workbooks._Open(filename, 0, false, 5, "", "", false, Excel.XlPlatform.xlWindows,"", true, false, 0, true);
Excel.Worksheet excelWkSheet = (Excel.Worksheet)excelWkBook.ActiveSheet;Excel.Range excelRange = excelWkSheet.UsedRange;
//Problems is here:excelRange.Cells.Font.Size = 8;excelRange.Columns.AutoFit();//No more problems...
excelWkBook.Close(true, filename, null);excelApp.DisplayAlerts = true;
excelWkBook = null;return true;}finally{excelApp = null;}}
I have come from VB6 environment and simmilar code worked great in VB6. In C# for some reason <excelRange.Cells.Font.Size = 8; > - puts the whole row into the first cell instead of just changing the font and <excelRange.Columns.AutoFit();> - simply doesn't do anything.
Other than that the code works fine. The file name passed to the procedure is a simple tab-dilimeted .txt file, that I want user to be able to reformat as excel if appropriate flag is specified.
The stack trace shows the following:
StackTrace = " at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)\r\n at Microsoft.Office.Interop.Excel.Range.get_CurrentArray()"
What the .get_currentArray() has to do with anything?
This problem drives me nutts! Any help is greatly apprecited!
Lentyai.
