However GetModuleFileNameEx does not return the name of the process/Modulename as VB or Access does
Can anybody help?

| 2. Re: Modulename not returned by GetModuleFileNameEx #4432 | Getting Closer - found something in this forum that applies:
Changed:
Public Declare Function GetModuleFileNameEx Lib "PSAPI.DLL" Alias "GetModuleFileNameExA" _
(ByVal hProcess As Long, _
ByVal hModule As Long, _
ByVal lpFileName As String, _
ByVal nSize As Long ) As Long

&
Changed:
lRet = GetModuleFileNameEx(hProcess, Modules(1), ModuleName, nSize)
to:
lRet = GetModuleFileNameEx(hProcess, Modules(1), VARPTR(ModuleName), nSize)
gives me:Lret=32hProcess=148 Modules(1)=16777216ModuleName=C:\WINDOWS\system32\services.exe exe
Does anybody have any ideas on how to return the PID(processID) from 16777216?
| 3. Re: Modulename not returned by GetModuleFileNameEx #4458 Posted by: JohnK 2004-06-15 02:58:03 | Be sure to check you are using GetModuleFileNameEx and not GetModuleFileNameExA! Case is important. Also, if you pass a UDT to these api's you should make sure the pointer is correct. I have noticed that if I pass a UDT the API doesn't run, You must then make a QMEMORYSTREAM
.WriteUDT()
Then pass the pointer (QMEMORYSTREAM.pointer) to the API. This is confusing in the DOCs, but is explained in it. I think you can pass the UDT only if your UDT is very simple.
