Question

How to identify the current active worksheet is minimized ?
I do not want to run my operation when the current worksheet in excel is minimized. I am using excel interop and C#

Answer 1

You can do a conditional check on the following property,

If Application.WindowState = xlMinimized Then
        // do something
End If 

This is in VBA though.

Here is a basic code in C#

using Excel = Microsoft.Office.Interop.Excel; 

Excel.Application myXL = new Excel.Application();
myXL.Visible = true;

//adding a new book
Excel.Workbook xlBookN = myXL.Workbooks.Add();

//opening exising book
String xlPath = "c:/myprojects/test.xls";
Excel.Workbook xlBookE = myXL.Workbooks.Open(xlPath,
    0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",
    true, false, 0, true, false, false);

Dim myWindowState As XlWindowState //you could also use a variable
myXL.WindowState = myWindowState

//or you can check the state directly 
If (myXL.WindowState = xlMinimized)
        // do something
End If 

Please check on the syntax and references.
