DarkMatter Posted March 24, 2008 Share Posted March 24, 2008 I'm doing this just to get a better handle on Dll calling. I am having issues calling C:\windows\system32\pdh.dll. I'm sure it has something to do with the variable types I am using in calling the functions but I am unsure. Does anyone have any exsperiance calling PDH.DLL? Here is my code: Dim $QueryHandle Dim $Counter Dim $lData Dim $Percent = 0 Init() While 1 DllCall("pdh.dll", "int", "PdhCollectQueryData", "long", $QueryHandle) $Percent = DllCall("pdh.dll", "double", "PdhVbGetDoubleCounterValue", "long", $Counter, "long", $lData) ConsoleWrite($Percent[0] & @CRLF & $Percent[1] & @CRLF & $Percent[2] & @CRLF) Wend Func Init() DllCall("pdh.dll", "long", "PdhVbOpenQuery", "long", $QueryHandle) DllCall("pdh.dll", "long", "PdhVbAddCounter", "long", $QueryHandle, "str", "\Processor(0)\% Processor Time", "long", $Counter) DllCall("pdh.dll", "int", "PdhCollectQueryData", "long", $QueryHandle) DllCall("pdh.dll", "double", "PdhVbGetDoubleCounterValue", "long", $Counter, "long", $lData) EndFunc The odd thing is I am not getting any errors when I check @error but my return value on $Percent is always nothing. Any ideas? [sub]Quantum mechanics: The dreams stuff is made of[/sub] Link to comment Share on other sites More sharing options...
