Has anybody been successful calling a DLL from a script?

I tried using the example provided with GWD documentation to launch IE but I got an error message about a missing "(".

Anybody with better luck doing this?

Add comma at the end of the line:

"ippppi", hwnd, lpszOp, lpszFile, lpszParams


it should be

"ippppi", hwnd, lpszOp, lpszFile, lpszParams,

instead of

"ippppi", hwnd, lpszOp, lpszFile, lpszParams

The example works and that specific DLL launched correctly.

Now I am trying to call a DLL that accepts three char * variables to do searches and return the results to GWD. However, GWD is blowing up. I think I am setting up the calls correctly, but not sure if the CallDLLFunc is liking the inputs.

Thoughts?


#include
#include

int _SearchCoolCopy(char *filename, char *WorkingDir, char *result)
{
int nErr;
int nRet;

MsgBox(filename, MB_OK);
MsgBox(WorkingDir, MB_OK);
MsgBox(result, MB_OK);
nRet = (int)CallDLLFunc(&nErr, "CoolUtil.dll", "GetCoolFilePath","ppp", filename, WorkingDir, result);

if(nErr)
{
switch(nErr)
{
case -1: MsgBox("Wrong parameters", MB_OK); break;
case -2: MsgBox("Error loading CoolUtil.dll", MB_OK); break;
case -3: MsgBox("GetCoolFilePath function does not exist", MB_OK); break;
default: MsgBox("Unknown error", MB_OK);
}
}
else
{
//success calling DLL
MsgBox("Null result from calling GetCoolFilePath successfully", MB_OK);
}
return nRet;
}

void _DummyFunction(void)
{
int nErr;

(int)CallDLLFunc(&nErr, "CoolUtil.dll", "DummyFunction","");

if(nErr)
{
switch(nErr)
{
case -1: MsgBox("Wrong parameters", MB_OK); break;
case -2: MsgBox("Error loading CoolUtil.dll", MB_OK); break;
case -3: MsgBox("DummyFunction function does not exist", MB_OK); break;
default: MsgBox("Unknown error", MB_OK);
}
}
else
{
//success calling DLL
MsgBox("Null result from calling DummyFunction successfully", MB_OK);
}
}


int main(void)
{
char *filename = "test.txt^#92;0";
char *WorkingDir = "C:^#92;^#92;^#92;0";
char *result;

result = (char *) malloc(256);

_SearchCoolCopy(filename, WorkingDir, result);
_DummyFunction();

return 0;
}
