Re: Domodal returning -1 value in dll
You should step in and debug from DoModal onwards. Its very likely that
the resource of the dialog cannot be found. What sort of DLL is it? You
should typically use a MFC Extension DLL. If you are using a Regular
DLL, you will need to use AFX_MANAGE_STATE before using resource in the
DLL.

Hi all
I am deveolping a sample application to connect a dll to exe.When I try
to show some dailog in Dll using domodal(),the function is returning -1
value.
Code in Dll:
extern __declspec(dllexport) int mine(int ncaller)
{
Cdone yk;
int nRet;
nRet=yk.DoModal();
switch ( nRet )
{
case -1:
AfxMessageBox("Dialog box could not be created!");
break;
case IDOK:
// Do something
AfxMessageBox("pressed on ok");
break;
case IDCANCEL:
// Do something
AfxMessageBox("pressed on cancel");
break;
}
return ncaller;
}
code in exe:
typedef int (*DLLPROC) (int);
int l;
HINSTANCE hinstDLL;
DLLPROC HelloWorld =NULL;
hinstDLL = LoadLibrary("xxxx.dll");
if (hinstDLL != NULL)
{
HelloWorld = (DLLPROC) GetProcAddress(hinstDLL, "mine");
}
l=HelloWorld(13);
there are no errors and I am able to return the value of 13 back from
dll.But Dialog is not getting displayed with Domodal(),it is returning
-1 value.
Can anybody through some light on this ?
Thanks in advance.
