See more: C# Excel Interop , +
Hello,

I use a WebBrowser control to open an Excel file.

The problem is that if there is already an open Excel before, the WebBrowser uses the same instance of Excel (Application).

Is there a method to indicate that the WebBrowser should create a new instance of Excel?

Or is it possible to force (or prevent) new Excel files to open in a specific instance?

thank you

If i understand you well...

MS Excel is a single-instance application, which means that Excel will open next file in the same instance. To force creating another instance, using Interop, you need to open it using new keyword.
Excel.Application oExcFirstInstance = new Excel.Application();
Excel.Application oExcSecondInstance = new Excel.Application();
 
oExcFirstInstance.Workbooks.Open(...);
oExcFirstInstance.Workbooks.Open(...);
oExcFirstInstance.Workbooks.Open(...);
 
oExcSecondInstance.Workbooks.Open(...);
oExcSecondInstance.Workbooks.Open(...);
oExcSecondInstance.Workbooks.Open(...);

I know that.
The problem is that I use WebBrowser, and I can not use it.
