Question

I am new to Excel addin programming. I created an Excel addin for Excel 2010 in C# which will create button in every sheet of workbook.

Can some one tell me what is wrong with this code:

Excel.Worksheet activeWorksheet = Globals.ThisAddIn.Application.ActiveWorkbook.ActiveSheet;
Microsoft.Office.Tools.Excel.Worksheet vstoWorksheet = activeWorksheet.GetVstoObject(Globals.Factory);
Excel.Range selection = vstoWorksheet.Range[2, 2];
Microsoft.Office.Tools.Excel.Controls.Button button = new Microsoft.Office.Tools.Excel.Controls.Button();
button.Tag = vstoWorksheet.Controls.AddControl(button,selection, "Click"); button.Name = "Click";
button.BackColor = System.Drawing.Color.Cyan;
button.Text = "Click";

Answer 1

I see the problem:

button.Tag = vstoWorksheet.Controls.AddControl(button,selection, "Click"); 

Should be:

vstoWorksheet.Controls.AddControl(button,selection, "Click");
