dll from win32 console.

Once again, please put <pre> tags around your code so we can read it clearly, it is not easy to understand what your code is trying to do without it. As to your code, I still do not understand (and you have not explained) what you are trying to do with this dll; which, incidentally seems to change with every reply you post. Forget everything you have done in the past and try to explain clearly exactly what you are trying to achieve.

Now my code looks like this. My application launching but crashing. [pre] void CClientRevProjDlg::OnBnClickedButton1() { typedef VOID (*MYPROC)(HWND); HINSTANCE hinstLib; MYPROC ProcAdd; BOOL fFreeResult, fRunTimeLinkSuccess = FALSE; HWND h = AfxGetMainWnd()->GetSafeHwnd(); // Get a handle to the DLL module. hinstLib = LoadLibrary(L"C:\\Users\\DasmahapatraS\\Projects\\Bhagavan_Cadem\\RevolutionProj\\debug\\RevolutionProj.dll"); // If the handle is valid, try to get the function address. if (hinstLib != NULL) { ProcAdd = (MYPROC) GetProcAddress(hinstLib, "runAppli"); // Do add operation // If the function address is valid, call the function. if (fRunTimeLinkSuccess = (ProcAdd != NULL)) (ProcAdd) (h); // Free the DLL module. fFreeResult = FreeLibrary(hinstLib); } // If unable to call the DLL function, use an alternative. if (! fRunTimeLinkSuccess) printf("message via alternative method\n"); } [/pre] ///////////////////////////////////////////////////////////////////////////////////// And runAppli like this... [code]
extern "C" BOOL __declspec(dllexport) runAppli(HWND h)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
// HWND h = AfxGetMainWnd()->GetSafeHwnd();
ShowWindow(h,SW_SHOW);
return true;
}[/code]

1. You still have not properly used <pre> tags around your code as requested. 2. You are really wasting your time with this; as I said before forget using this DLL as it serves no purpose. Create an application as an application and do things the right way.

:) I need this dll to work Richard. Its very important......My application should be served as a dll. And my mainwindow should appear.

Why do you persist with this? This is totally contrary to the design of Windows applications. Putting all this code into a DLL is just going to cause you problems and, as I have said repeatedly, serves absolutely no purpose. Perhpas if you actually explained what problem you are trying to resolve someone can advise you of a potential solution, but just insisting that you need this as a DLL makes no sense.

window handle is creaeing all the problem check this I am trying to get the handle like this [code] HWND h = this->m_hWnd; [/code] from the dialog class.....This is giving problem.....PLease tell me how can I get the window handle from dialog class. HWND handle. If I get the correct handle then it'll launch the application. Thanks Sujan

Problem I have explained earlier also. I have built one application in mfc...Now I want to launch that application from another aplication. so I want to make the first application as dll and try to laucnh that application from my 2nd application. Howelse would that be achieved except dll. ??? you tell me. Thanks Sujan

Sorry, but I don't understand what you are saying. The last few messages you were trying to launch an MFC application held inside a DLL, and now you seem to be doing something else that does not make sense. Where does this dialog fit in to what you have been talking about? And you still have not figured out how to add <pre> tags around your code!

This has nothing to do with DLLs; I can only repeat: this is not the way to do it, DLLs are shared libraries not stand alone applications. If you want to launch a second application from a first then use one of the proper API functions[^].

HWND is a public member of CDialog -- you can access it just like any other member of CDialog class.
HWND CMyDialog::GetHandle()
{
return m_hWnd;

No,
HWNDis a type defined in Windows.h.Unrequited desire is character building. OriginalGriff I'm sitting here giving you a standing ovation - Len Goodman

}when I try to access the m_hWnd from my dialog it says "unused ???"....Why is it so . [code] MyView::OnButtonClick() { HWND h = m_hWnd; //h is coming as unsed ??? its not getting good value. } [/code] Please tell me whats going wrong in this ? Thanks Sujan
