It works for popup menus, but not for the menus attached to windows. It would work for menus attached to windows if you overrode WM_INITMENU and WM_INITMENUPOPUP and prevented the default processing and overrode OnIdle() in your application class and prevented the default processing. I wouldn't recommend doing this though, because it may break other parts of the program.

I tried at:
void CAlarmWnd::OnUpdateFrameMenu(HMENU hMenuAlt)
I will try as
void CAlarmWnd::OnInitMenu(CMenu* pMenu)
{
CFrameWnd::OnInitMenu(pMenu);
GetMenu()->GetSubMenu(1)
->EnableMenuItem(ID_BT_AL_RISED, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);
// TODO: Add your message handler code here
}
_____________________
and -not works.
Surely - such a method must be presented - for any kind of menu
(or any pixel) - so is design of MFC.

works if to change to BY_POSITION action
GetMenu()->GetSubMenu(1)
->EnableMenuItem(postion, POSITION | MF_DISABLED | MF_GRAYED);

what is a message identifier?

Hi,
MSDN say 
==
message identifier
A unique value that identifies a message. System-defined messages use named constants, such as WM_PAINT, as message identifiers. Windows CE reserves message-identifier values in the range 0x0400 through 0x7FFF for application-defined messages.

hello ranjani
In modular programming like C++ and VC++ the control o fprogram passes from one area to another based on certain conditions . usually u do it with goto function in C but here in OOPS the control transfers from one line to another by message ids . ie when the user clicks on a menu a message like WM_COMMAND(menuitem , handler) -- here the first param in the WM_COMMAND is the menu item which the user clicked and the second item is the function name which will be fired once the message is fired . So U write whatever u want to do in the menu item here inside the handler that way the control of program gets transferred to the handler function . also other type of messages are also there like
system messages like WM_CLOSE , ON_FILE_OPEN like that but the handlers r already written for them . another type is POST_THREAD_MESSAGE ( MESSAGE) here the message can be posted by any object of a Class CWinThread and the handler function can be written for this mesasge also as mentioned above . hope u will find more info from msdn ( clumsy huh??) dharanibabus@hotmail.com

Hi there,
I need to select multiple files in an openfiledialog in MFC, but I use this:
CFileDialog *cfd=new CFileDialog, true, ...., NULL, OFN_FILEMUSTEXIST | OFN_ALLOWMULTISELECT, .... , NULL)<br />
<br />
CString x;<br />
cfd->DoModal();<br />
x=cfd->GetPathName();<br />
How can I convert this code to get more then one file???

Hi student 
To allow the user to select multiple files, set the OFN_ALLOWMULTISELECT flag before calling DoModal. You need to supply your own filename buffer to accommodate the returned list of multiple filenames. Do this by replacing m_ofn.lpstrFile with a pointer to a buffer you have allocated, after constructing the CFileDialog, but before calling DoModal. Additionally, you must set m_ofn.nMaxFile with the number of characters in the buffer pointed to by m_ofn.lpstrFile.

I don't understand this part (I've read it to in the MSDN); that's why I put it on CP. Can you give me some code, jsut for initializing the buffer, and filling it with those files?

Hi,I am a beginner in MFC of VisualC++.now i have a problem to be solved.
Somebody can help me?
I want to draw some text in CEditView via DrawText function,but it display nothing on CEditView.
some code below:
void CTPlatformView::OnDraw(CDC* pDC)
{
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here
CRect rect;
GetClientRect(&rect);
pDC->DrawText("hello",&rect,DT_LEFT);
}
Thanks!!

Hi,
Look what MSDN say about:
==
virtual int DrawText( LPCTSTR lpszString, int nCount, LPRECT lpRect, UINT nFormat );
...
This member function uses the device context’s selected font, text color, and background color to draw the text. Unless the DT_NOCLIP format is used, DrawText clips the text so that the text does not appear outside the given rectangle. All formatting is assumed to have multiple lines unless the DT_SINGLELINE format is given.
If the selected font is too large for the specified rectangle, the DrawText member function does not attempt to substitute a smaller font.
If the DT_CALCRECT flag is specified, the rectangle specified by lpRect will be updated to reflect the width and height needed to draw the text.
==
Hope, now youself can do checks and find answer.

Thank you Vitali!
if i let CMyView to derive from CView,it can directly display "hello".but it cann't if derived from CEditView.
why?

|
|

Check under debugger what values have settings pointed above
in the first and second variants.
hope it will help.

I think you should use the GetEditCtrl () method to acces the CEdit object associated with the CEditView. Then write text in the CEditView just like you were using CEdit.

OnDraw() doesn't get called for a class derived from CCtrlView, such as CEditView. You have to do it in OnPaint().
Hope this helps,

Hi,Ryan Binns and all of you
Thank you very much! I've solved it via OnPaint() function.

Hi,
I've created a directory selection dialog (thanks to some people here at CP), but I thought it's nice to have some of creating a folder from this dialog. I you can't, you have to creat one yourslef, using explorer. I know how to create a folder in MFC, but you can use that function from the dialog!
Help me please,
|
|
|
|
|
Why can't you create a folder? What is happening?
Who is 'General Failure'? And why is he reading my harddisk?!?
|
|
|
|
|
No,
I just need to get a button (called new directorie, or something) to create a new directory, without having to rewrite this diialog.
So, do you know wether there is some kind of flag to enable this sort of feature?
|
|
|
|
|
What dialog are you using?
A standard one or a homegrown dialog?

Here's my code, it's very standard (got parts of it from people at CP )
BROWSEINFO* b=new BROWSEINFO(); <br />
LPTSTR buf=new TCHAR[MAX_PATH]; <br />
<br />
int image=-1; <br />
b->hwndOwner=this->m_hWnd; <br />
b->iImage=image; <br />
b->lpszTitle="Please select a directory for your input:"; <br />
b->pidlRoot=NULL; <br />
b->pszDisplayName=buf; <br />
b->ulFlags=BIF_BROWSEINCLUDEFILES; <br />
<br />
LPITEMIDLIST x=SHBrowseForFolder(b); <br />
if(x==NULL)<br />
{<br />
return;<br />
}<br />
<br />
<br />
LPTSTR buf2=new TCHAR[MAX_PATH]; <br />
<br />
<br />
bool gelukt=SHGetPathFromIDList(x,buf2);<br />
<br />
<br />
CString pad=buf2;<br />
<br />
if(!gelukt)<br />
{<br />
error_scherm e;<br />
e.set_text("It seems that the directory you've selected is corrupt, if this problem persists please contact the developer.");<br />
e.DoModal();<br />
return;<br />
}<br />
<br />
delete [] buf;
delete [] buf2;<br />

You need to include the style BIF_NEWDIALOGSTYLE with your SHBrowseForFolder.
simply AND it into the ulFlags:
b->ulFlags=BIF_BROWSEINCLUDEFILES & BIF_NEWDIALOGSTYLE;
You then get a slightly different dlg, but that is newer one.
