Rather than creating the CView, create a CSplitterWnd.

_tcslen returns a size_t which I think is an unsigned int. All you need to do is change pnInt to a size_t* or an unsigned int*.

Hi I am doing large application So i want to devlope my Resources like Dialog,Icons,Bitmap in .Dll and call from .exe .

no need for the link do the following.
Put all the dll, menu, icons etc in the resrouce only dll,

in the initinstance of your mfc application Load the resource dll using

hRes = LoadLibrary(....);
if(hRes)
   AfxSetResourceHandle(hRes);

This will make your dll resource same as ur exe resource. You can use
loadicon, loadmenu etc without passing the resouce handle.

When you want to get the resource handle

AfxGetResourceHandle();

Was, by any chance, your modeless dialog done like this?

SomeFunctionOrOther()
{
CMyModeless dialog;

dialog.Create(...);

}

If so, then it's nothing to do with DLLs or anything as complicated, it's more to do with the fact that modeless dialogs cannot be done that way.
You'd need

CMyModeless* dialog;
dialog = new CMyModeless();
dialog->Create(...);

since you want the object to exist beyond the lifetime of a frame-based object.

Of course, this doesn't even come close to covering the fact you'd need to either track the dialog object's lifetime, or make it suicidal.

I guess, the MFC DLLs are not present in the target system.

Nor should they be, unless the machine also has Visual Studio installed. The 'debug' libraries are not distributable.

The 'D' at the end of the DLL name signifies that you are trying to run a debug built application on the target machine.
Recompile your program in release mode and it should run OK.
(most machines should have the Microsoft runtime libraries installed)

Query: Keyboard Hooks!

Nirav Doshi16-Mar-04 1:14

Nirav Doshi

16-Mar-04 1:14

Hello,

I have an application which hooks up the keyboard of a given process by injecting a DLL into the process.

Now in that DLL, I have a (shared) char buffer which stores each keystroke. I am trying to get the buffer from my application, which is failing! Is there anything I am missing here? Unsure | :~

:

Here's how my code goes:

<code>
...
#pragma data_seg(".WBA")
char	g_chBuffer[0x101];
#pragma data_seg()
#pragma comment(linker, "/section:.WBA,rws")

...
BOOL _declspec(dllexport) __stdcall GetAppBuffer(char *chfBufferOut)
{
    if(chfBufferOut == NULL)
    {
	return	FALSE;
    }

    char *pchBuffer = g_chBuffer;               // Here somehow, g_chBuffer is EMPTY! :((

    while((*chfBufferOut++ = *pchBuffer++) != 0);

    return	TRUE;
}
...

LRESULT _declspec(dllexport) CALLBACK GetKeyboardMsgs(int nCode, WPARAM wParam, LPARAM lParam)
{
...
    static char *pchBuffer = g_chBuffer;
...
    ToAscii(wParam, nScan, chKeyState, &wTemp, 0);
    *pchBuffer++ = char(wTemp);                      // The buffer is fine here
...
}
</code>

In my application code, where I am calling the function GetAppBuffer():

...MyFunction()
{
...
    static BOOL (__stdcall *fpGetAppBuffer)(char *) = NULL;
    if(m_hmodDLL != NULL)
    {
	memset(chBuffer, STRING_TERMINATOR, 0x101);
	fpGetAppBuffer = (BOOL (__stdcall *)(char *)) GetProcAddress(m_hmodDLL, "GetAppBuffer");
    }
...
    char chBuffer[0x101];
    memset(chBuffer, 0, 0x101);
    fpGetAppBuffer(chBuffer);            // It gets an empty chBuffer back! :(
....
}
</code>

Please reply with any of your comments/suggestions. Is there anything wrong, that I am doing here? Please write back even if you feel the question/code is not clear/insufficient.

Thanks!
Rgds,

tree icon [+] [-]

Hi!

I wanted a tree control with different back color, line color, and [+/-] icon. To archive the former, I tried CTreeCtrl::SetBkColor and CTreeCtrl::SetLineColor, then it works. But there is trouble with the default [+/-] icon.

I wanted the [+/-] inside a circle. I created 2 icons in resource for that, then tried CWnd::SetIcon big/small for +/-, but the default icon never changes. What should I do?

Thanks,
Sovann.

Check this article:
QA: How can I change the background color of a Tree Control?[^]
It is not only about changing the background color, it also addresses your proble and although it was written for the Pocket PC, I think you will be able to use this code on the desktop as well.

deploying a .dll dependent on MFC71.dll

Andy C16-Mar-04 0:37

16-Mar-04 0:37

I've been writing a DXi .dll (Sound module) using .Net 2003 and am just about to release Beta 1 for testing. However the damn thing won't register on any machine that doesn't have .net 2003 installed. The documentation implies that MFC71.dll and MSVCR71.dll will be needed in the distribution.

So, I'm trying to get the MS deployment tool working. It's still no go. The installation fails trying to register the .dll file. I'm presuming I need to register MFC71.dll etc ?

Any clues ?
