Debugging VSTO with a Command Argument
I am developing an Excel Add-In, and I'm seeing some bugs that are coming up when people start Excel by opening a Workbook. If they start Excel and then open a Workbook, everything is fine, but otherwise there are issues.
The problem is, I don't know how to debug this, as I can't start the debugger with an Excel command argument (as far as I know).
I'll add some detail as requested:
Inside the ThisAddIn.cs, I have 2 blocks of code that are giving me problems.
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
try
{
if (isStarted) return;
var xl = this.Application;
xl.WorkbookOpen += WorkbookOpened;
xl.SheetActivate += Workbook_SheetActivate;
var workbook = Application.ActiveWorkbook;
WorkbookOpened(workbook);
isStarted = true;
}
catch (Exception ex)
{
logger.LogIt($"Error 01 - {ex.Message}");
}
}
and:
private void WorkbookOpened(Excel.Workbook workbook)
{
try
{
if (!isStarted)
{
var xl = this.Application;
xl.WorkbookOpen += WorkbookOpened;
xl.SheetActivate += Workbook_SheetActivate;
isStarted = true;
}
int key = Application.Hwnd;
dynamic srVers = null;
if (workbook.CustomDocumentProperties.Count == 0) return;
var srType = workbook.CustomDocumentProperties("InternalDocType");
try
{
srVers = workbook.CustomDocumentProperties("Version");
}
catch (Exception)
{
srVers = null;
}
if (srType.Value != "OurType") return;
Globals.Ribbons.prRibbon.WorkbookOpened(workbook);
}
catch (Exception ex)
{
logger.LogIt($"Error 06 - {ex.Message}");
}
}
When someone starts Excel and opens the workbook, there are no errors. However, if someone opens Excel by opening the workbook (double-click in File Explorer, or right click Excel and choosing the workbook) I get the Error 06 then Error 01, both with "Object reference not set to an instance of an object."
Any suggestions?

@ESDictor, you can directly pass the path of the excel file as command line argument in visual studio.
