I Need more Performance information using VB

Hi,

I want to test performance of oure desktop application and write the results to an Excel file. Performance not only in elapsed time but also used memory.

Now I use Win32API.GlobalMemoryStatus to get available memory. But the available counters here do not change as I expect, so I think I need other memory invormatio.

In the Performance Counters, there is a counter available Memory - Commit Bytes

Now this seems to be the info I need. But How can I use this in my VB script

I found that this counter is availeble in the GetPerformanceInfo API, but cant find an example hou to use this API.

Can anybody help me with this one?
