Include afxwin.h, remove statement #include <windows.h> , if there is any.

I wonder, why you needed to use this?

If I include afxwin.h it showing the following error,
fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>
What i have to do...

Remove line #include <windows>, if there is any.

I removed windows.h from stdafx.h and included afxwin.h in my header file.Now it is not recognizing the InvokeHelper and it's parameters.Giving error as
error C2065: 'InvokeHelper' : undeclared identifier
error C2065: 'DISPATCH_METHOD' : undeclared identifier
error C2065: 'VT_EMPTY' : undeclared identifier
What would be the problem...

How do you expect to use an OCC_SUPPORT method by using the _AFX_NO_OCC_SUPPORT macro to ommit
OCC support in the MFC code??
Get rid of that macro!
*EDIT* You probably shouldn't be messing with AFX_CDECL either unless you know what you're doing.
Look at the declaration for CWnd::InvokeHelper()...
#ifndef _AFX_NO_OCC_SUPPORT
COleControlSite* GetOleControlSite(UINT idControl) const;
void AFX_CDECL InvokeHelper(DISPID dwDispID, WORD wFlags,
...
See why it won't work with that macro?

Hi
When i use CDialogTemplate class in my application, then there is error occure as error C2065: 'CDialogTemplate' : undeclared identifier, so to use this class is there is need to include any Header file in code.

Its declared in afxpriv.h. But why you needed to use this class ?
Refer this[^] link for more information.

Off the top of my head the answer would be YES! A template is just an outline of the code which the compiler needs to generate. That means that without the outline it can not generate it. Therefore it does not exist and can not exist until you provide the outline for it.
Bottom line: Include the header for any template that you wish to use.

Hi,
In my application there is two window.
I have used PreTranslateMessage
In that i have written
bool nFlag = CDialog::PreTranslateMessage(pMsg);
if(pMsg->message==WM_KEYDOWN)
{
if(IsCTRLpressed() && IsALTpressed())
{
if(IsDpressed())
{
//delete code
}
}
}
It is wroking on 2000 pro. but in XP
it's not wroking can any one tell me WHY?
what is wrong with it?
Thanks,
Rushiraj

What do you mean by not working ?

IsCTRLpressed() looks like
#define IsCTRLpressed() ( (GetKeyState(VK_CONTROL) & (1 << (sizeof(SHORT)*8-1))) != 0 )
#define IsALTpressed() ( (GetKeyState(VK_MENU) & (1 << (sizeof(SHORT)*8-1))) != 0 )
#define IsDpressed() ( (GetKeyState('D') & (1 << (sizeof(SHORT)*8-1))) != 0 )
and when I press CTRK+ALT+D I want to execute delete function.
now when I press CTRK+ALT+D
IsCTRLpressed returns true
IsALTpressedreturns true
but
IsDpressed returns false
bool nFlag = CDialog::PreTranslateMessage(pMsg);
if(pMsg->message==WM_KEYDOWN)
{
if(IsCTRLpressed() && IsALTpressed())
{
if(IsDpressed())
{
delete();
//delete code
}
}
}
Thanks,
Rushiraj

No need for this complex definition, simply
#define IsCtrlDown() ((GetKeyState(VK_CONTROL)<0)?TRUE:FALSE)
this will do.
rushiraj.jhala wrote: but
IsDpressed returns false
You are handling the WM_KEYDOWN in PreTranslateMessage, so no need for IsDPressed, check
pMsg->wparam == 'D'
This will work in all the versions
-- modified at 3:09 Friday 23rd March, 2007
Also you can change the definition global to all keys as below,
#define IsKeyDown(nKeyCode) ((GetKeyState(nKeyCode) < 0)?TRUE:FALSE))
and you can call this as,
IsKeyDown(VK_CONTROL);
IsKeyDown(VK_MENU);

hi,
Thanks
But it is also not wroking,
I get
pMsg->wParam = 18.
Thanks,

rushiraj.jhala wrote: pMsg->wParam = 18
How did you check yhis value? 18 is Alt(VK_MENU) key...
Use the below code segment,
if ((pMsg->message == WM_KEYDOWN) && (pMsg->wParam == 'D'))
{
if (IsKeyDown(VK_CONTROL) && IsKeyDown(VK_MENU))
{
/* Ctrl+Alt+D is pressed */
}
}

Jus try d below...
#define IsKeyDown(nKeyCode) ((GetKeyState(nKeyCode) & (1 << (sizeof(SHORT)*8-1))) != 0)
and in Pretranslate Message,
if (IsKeyDown(VK_MENU) && IsKeyDown(VK_CONTROL) && IsKeyDown('D')){
delete();
}

Hey Megha,
i know you just have deleted the menu from the resource file but that can not solve your purpose .
As far as i know that there is no way you can hide or delete the menu from SDI or MDI.
if you are making SDI application then you can use the dialog based project and use it's view in accordance.

hey Pankaj,
see i got something using which u can remove menu from SDI..
i m pasting that code here. Actually it is mentioned for both SDI and MDI..
i m not able to put it for MDI.. see if u can do it.. let me know the same..
/****cotents from a document*********/
Steps to Create MDI Application that Has No Menu Bar
1. Generate an MDI application with AppWizard. Do not delete the IDR_MAINFRAME menu resource. If you have an application that was not generated with AppWizard, do not delete the corresponding main menu resource. Leaving the menu resource is required to avoid assertion failures in the MFC code.
2. Delete menu resources associated with MDI child windows (IDR_xxxTYPE). They are not used. By deleting them, you avoid a resource (memory) leak.
3. Override the PreCreateWindow() function for the CMainFrame class:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if(cs.hMenu!=NULL)
{
::DestroyMenu(cs.hMenu); // delete menu if loaded
cs.hMenu = NULL; // no menu for this window
}
return CMDIFrameWnd::PreCreateWindow(cs);
}
4. Modify the code responsible for switching menus by overriding the LoadFrame() and OnCreateClient() methods of CMainFrame. This is necessary because MFC has already loaded and switched menus automatically. The following shows what must be done:
// Overridden method declarations for CMainFrame
BOOL LoadFrame( UINT nIDResource,
DWORD dwDefaultStyle = WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE,
CWnd* pParentWnd = NULL, CCreateContext* pContext = NULL );
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs,
CCreateContext* /*pContext*/);
// Overridden method declarations for CMainFrame
BOOL CMainFrame::LoadFrame(UINT nIDResource, DWORD dwDefaultStyle,
CWnd* pParentWnd, CCreateContext* pContext)
{
return CFrameWnd::LoadFrame(nIDResource,dwDefaultStyle,
pParentWnd,pContext);
}
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs,
CCreateContext* /*pContext*/)
{
return CreateClient(lpcs,NULL);
}
NOTE: Instead of calling the base class (CMDIFrameWnd) in the override of LoadFrame, you call its base class, CFrameWnd, instead. That way you can avoid the code that deals with MDI menus.

You had already asked this question[^]and didn't even try to explain that was this the only message that's being shown.
Somethings seem HARD to do, until we know how to do them.

This is the only message what I got.
I have one deawing application in that I layers like photoshop

Now when I use this keys very quickly I got the message box with only text "A Required resource was" written on it.
Thanks,

Try debugging the code. I hear that other people use debuggers to solve this kind of problem and some even achieve success. It must be worth a try.

I have checked that each and every brush,pen created is deleted and every bitmap object selected is detched.
still I am not able to locate problem.
