 |
|
Hi,
I need help to create a DllCall again. This is the definition I have from the help file that comes with the dll: | Quote: | DWORD __stdcall FSL2EnumLayerExclude(LPCSTR fslGUID, DWORD index, LPSTR excludePathBuffer, LPDWORD excludePathBufferLen, LPDWORD excludeType)
Enumerates the exclude entries for a layer
Return Value
Returns one of the following
FSL2_ERROR_SUCCESS On success
FSL2_ERROR_LAYER_NOT_FOUND When done
Parameters
fslGUID Identifies the layer.
index Index of exclude entry to enumerate
excludePathBuffer On success will point the value of the exclude entry
excludePathBufferLen Pointer to the size of the excludePathBuffer On success will contain the size of the string stored in ExcludePathBuffer
excludeType On success will contiant the type of exclude entry |
This is what I got so far: | Code: | Loop, 5
{
ID := A_Index
VarSetCapacity(excludePathBuffer, 260)
excludePathBufferLen = 000
excludeType = 0
RetVal := DllCall("fsllib32\FSL2EnumLayerExclude"
, "Str", fslGUID
, "UInt", ID
, "Str", excludePathBuffer
, "UInt *", excludePathBufferLen
, "UInt *", excludeType)
excludes .= ID . " - " . RetVal . " - " . excludePathBuffer . " - " . excludePathBufferLen . " - " . excludeType . "`n`"
} |
I'm sure that the fslGUID I use is valid since other dllcalls work fine. But the return value indicates that the layer is not found. Did I specify the parameter types wrong?

can you share the dll?

Yes, It is belonging to SVS by Altiris. You can get the dll here.

The syntax looks correct. So, obvious question: Have you loaded the library at the start-up, which may be necessary for this?
| Code: | | DllCall("LoadLibrary", "str", "fsllib32") |
Or, you may have to specify the buffer length as input too:
| Code: | | excludePathBufferLen := VarSetCapacity(excludePathBuffer) |
