I am loading an extension dll from my mfc client application, when click on the menu first time the dll dialog is being loade and after i exit or close the dialog, and again clicking on the menu to load again it's giving error that "A required resource was unavailable". what could be the problem please help me to resolve this

[code]
void CTestRevApp ::On3DView()
{
typedef VOID (*MYPROC)(CString);

MYPROC ProcAdd;
BOOL fRunTimeLinkSuccess = FALSE;

hinstLib = LoadLibrary(L"C:\\Documents and Settings\\sdh\\My Documents\\REVOLUTIONPROJ_DB\\DllDialog\\package\\DllTest\\Release\\dlltest.dll");

if( hinstLib == NULL)
FreeLibrary(hinstLib);

ProcAdd = (MYPROC)GetProcAddress(hinstLib, "runAppli");
ProcAdd(NULL);
if(ProcAdd == NULL)
{
AfxMessageBox(L"Unable to get pointer to function runAppi()");
FreeLibrary(hinstLib);
hinstLib = NULL;
return;
}

return;
}
[/code]

Your code looks a little bit mixed up.

Try it this way. It should solve your problem:

C++

CTestRevApp::CTestRevApp()
{
    hinstLib = NULL;
}

CTestRevApp::~CTestRevApp()
{
    if (hinstLib != NULL)
        FreeLibrary(hinstLib);
}

void CTestRevApp::On3DView()
{
    typedef VOID (*MYPROC)(CString);

    MYPROC ProcAdd;
    if (hinstLib == NULL)
    {
        hinstLib = LoadLibrary(L"C:\\Documents and Settings\\sdh\\My Documents\\REVOLUTIONPROJ_DB\\DllDialog\\package\\DllTest\\Release\\dlltest.dll");

        if (hinstLib == NULL)
            AfxMessageBox(L"Unable to load library");
    }
    if (hinstLib != NULL)
    {
        ProcAdd = (MYPROC)GetProcAddress(hinstLib, "runAppli");
        if (ProcAdd == NULL)
            AfxMessageBox(L"Unable to get pointer to function runAppi()");
        else
            ProcAdd(NULL);
    }
}

It's not solving the problem. My Client application is still active when i am calling On3DView 2nd time, it's giving still error "A required resource was unavailable" and not laoding the dlg of the dll.

I have exactly copied your code it's still giving error.

The error is very probably in your DLL showing a dialog. Common sources are forgetting to release DCs and GDI objects.

Do you have the source code? If not, you must contact the supplier of the DLL. If yes, you must check the code.

If the code uses GetDC() somewhere, ensure that ReleaseDC() is called when the CDC is no longer used.

I am releasing it in the ::OnDestroy() fucntion of the view

Re: loading dll second time giving error "A required resource was unavailable"

That's one place where you release a DC (in your app or the DLL?). If not in the DLL, you should concentrate on the DLL code. There may be multiple places in your code using DCs and GDI objects. If you miss any release call or forget to de-select GDI objcets out of context, the error may occcur.

I can't really help you without seeing the code. I can only guess.
Check this example code:

C++

CDC *pDC = GetDC();
CPen NewPen(PS_SOLID, 0, m_Color);
CPen *pOldPen = pDC->SelectObject(&NewPen);
CFont *pOldFont = pDC->SelectObject(m_pMyFont);
// do something with the DC
...
// Don't forget to select the old objects
pDC->SelectObject(pOldFont);
pDC->SelectObject(pOldPen);
// Don't forget to release the DC
ReleaseDC(pDC);

I am not able to delete the view it's crashing

delete m_pNewView;

It's crashing. how can I delete the view.????

I'm sorry, but without knowing your code, I can't really help. Also, is there a relation to the original question, or is it a new one? If it is a new one, you should open a new question.

Views are usually handled by the document class and the frame work. To close a view manually, the parent frame of the view must be closed.

I'll reply again to this message. You have added too much unformatted code to your other posts (therefore somebody has donevoted them).

You should use the 'code' button on top of the CP message input window to format the selection as C++ code.
You should limit the amount of code. Nobody here will step through too many lines.

Regarding the CView deletion:
Why do you use a CView derived class within a CDialog? Using a CWnd derived class as user control should solve your problem. CView classes are used with the document view model and expect to have a frame window as parent.

The solution is to not use a CView derived class as a client window of a dialog.

i wanted a view on the dialog. so i derived from cview and created the view in the dialog. 1st time everything is coming fine. but without closing the client application if i try to launch again the dialog then it's giving error. Please give me some suggestion how can i get rid of it. Thanks

Re: loading dll second time giving error "A required resource was unavailable"

Jochen Arndt1-Mar-12 6:34

The problem is that the view is not properly closed. But even if you would close it properly, there will be other problems. A CView is not designed to be a child view of a dialog. It must be a child of a CFrameWnd derived class. Change your CView class to be based on a CWnd.
