Error opening system DLL -- any ideas?

This code causes an error when run on both Windows 2000 and XP:
Code: Select all
#TH32CS_SNAPHEAPLIST = $1
#TH32CS_SNAPPROCESS = $2
#TH32CS_SNAPTHREAD = $4
#TH32CS_SNAPMODULE = $8
#TH32CS_SNAPALL = (#TH32CS_SNAPHEAPLIST | #TH32CS_SNAPPROCESS | #TH32CS_SNAPTHREAD | #TH32CS_SNAPMODULE)
#TH32CS_INHERIT = $80000000
Structure PROCESSENTRY32
dwSize.l
cntUsage.l
th32ProcessID.l
th32DefaultHeapID.l
th32ModuleID.l
cntThreads.l
th32ParentProcessID.l
pcPriClassBase.l
dwFlags.l
szExeFile.b [#MAX_PATH]
EndStructure
CreateToolhelp32Snapshot_ (#TH32CS_SNAPPROCESS, 0)
; The error...
;---------------------------
;PureBasic180532712.exe - Bad Image
;---------------------------
;The application Or DLL C:\winnt\System32\TOOLHELP.DLL is not a valid Windows image. Please check this against your installation diskette.
;---------------------------
;OK
;---------------------------
Anyone got any idea what's wrong? The CreateToolhelp32Snapshot command is supported on all OSs according to MSDN. I get the same result with OpenLibrary/"toolhelp.dll"...

Hi James,
I recently discovered Dependencywalker a very powerfull freeware tool to analyze dll functionning and interaction both static and dynamic.
Have a look at
http://www.dependencywalker.com/
Very instructive ...

Hi Michel,
Yeah, I've had that before (though thanks for the reminder!) -- it integrates well with a cool program called ProcessExplorer, from
www.sysinternals.com (they have lots of cool stuff like this). It looks like the problem may be a PB bug, though, as the function works when called from Blitz; I've now posted it in the Bug Reports forum...

I'm getting the same error as Hi-Toro when parsing a DLL. Here is my code:
Code: Select all
If OpenLibrary(0,"C:\Program Files\Common Files\Acronis\Drivers\setup16.dll")
SetErrorMode_(#SEM_FAILCRITICALERRORS) ; Doesn't suppress error prompt. :(
If ExamineLibraryFunctions(0)
While NextLibraryFunction() : Debug LibraryFunctionName() : Wend
EndIf
CloseLibrary(0)
SetErrorMode_(0)
EndIf
And the MessageBox error prompt that comes up when using it:
Code: Select all
---------------------------
PureBasic_Compilation0.exe - Bad Image
---------------------------
The application or DLL C:\Program Files\Common Files\Acronis\Drivers\setup16.dll is
not a valid Windows image. Please check this against your installation diskette.
---------------------------
OK
---------------------------
[Edit] If I put CallDebugger before the OpenLibrary line, and step through
it, the OpenLibrary command is failing without returning 0. So this is actually
a PureBasic bug.

SetErrorMode should be called first, this way it works fine.
Code: Select all
SetErrorMode_(#SEM_FAILCRITICALERRORS) ; Doesn't suppress error prompt. :(
If OpenLibrary(0,"C:\Program Files\Common Files\Acronis\Drivers\setup16.dll")
If ExamineLibraryFunctions(0)
While NextLibraryFunction() : Debug LibraryFunctionName() : Wend
EndIf
CloseLibrary(0)
EndIf
SetErrorMode_(0)

Thanks ABBKlaus!
I'm getting too old for this stuff.
