Im afraid this doesn’t appear to be working when using excel 2003.

It seems that all the excel.exe processes share the same Hinstance.

This happens to me with excel opened before and after my application starts with this code.

I have a different approach which isn’t 100% but closes the correct excel application.

***
When creating the excel application instance i make a note of the time before and after the instance is created

Dim xlApplication As Application
Dim xlApplicationStartTime1 As DateTime
Dim xlApplicationStartTime2 As DateTime

xlApplicationStartTime1 = DateTime.Now()
xlApplication = New Application
xlApplicationStartTime2 = DateTime.Now()

” For the kill process, I check the StartTime of the process

For Each p As Process In Process.GetProcessesByName(”EXCEL”)

If p.StartTime >= xlApplicationStartTime1 And p.StartTime

Thank you so much Sodeve,

This little part of code you wrote has saved my life. I really digged inside many different ebooks or even inside msdn and couldn’t find this simple solution.

The same solution for word (if needed):

foreach (Process p in Process.GetProcessesByName(”WINWORD”))
{
int baseAdd = p.MainModule.BaseAddress.ToInt32();

//oXL is Excel.ApplicationClass object
if (baseAdd == oXL.Hinstance)
p.Kill();
}

Many thanks again.. god bless you my friend..

Ata..

Process[] procs = Process.GetProcessesByName(”EXCEL”);
foreach (Process p in procs)
{
p.Kill();
}

I’ve tried your code and I noticed that Excel applications that were opened AFTER my application started are also being closed. Any suggestions?

It is interesting to note that the previous Excel version (we tested it on Office 2003) a new Excel.Exe process will be created everytime we open a document.

But in Office 2007, only one Excel.Exe exists in the memory. No matter how many documents you open.

Did u actually try to execute the above code when multiple instances (processes) of excel are running in task manager? p.MainModule.BaseAddress always returns the memory address of Excel.exe (not of the particular excel instance) and hence the above code kills all the excel processes running in the server.
