Hi all,
I created a window( I didn't call the ShowWindow(), so it is unseen) and create a child window: a system tray icon and a popup menu attached to this icon. I want to disable some menu item of that popup menu.
I called the enable() method of that CMENU object, but no result. The return value are correct.
What can I do?
Need your help.

EIther you need to map the equivalent ON_COMMAND_UI handlers which when not present cause MFC code to enable a menu item by default if it has a handler or map the WM_INITMENUPOPUP message and enable/disable the items there.

I need to validate the user input for a textbox for a National Insurance Number format i.e. AANNNNNNA. A = alpha and N = numeric
Can anyone suggest a neat way to do this?

Yes, use regular expressions. You can use RegEx++ from the boost library (www.boost.org). http://www.javaworld.com/javaworld/jw-07-2001/jw-0713-regex.html is the first result of http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=regular+expression+social+security+number&btnG=Google+Search,
but there are plenty more, so have a look around.

You should not have to compile or link in a whole library to validate the input of one text box.
Look for help topics in MSDN about custom DDV() routines.

He asked for a neat way. Not an efficient way. 
I'm a regular expressions junkie, though. I think it should be part of the C++ language specificatin myself, but that's just me. I accept the overhead of that library because of what it gives you. Again, that's just me.

What is a "neat" solution? There is only elegant solution. In MFC, I recommend overriding the on-change event handlers and can the edit text for the desirable input.

I'm assuming you have an modal dialog for entering a number of values.
First you need to decide when the validation should be performed. Directly when the user is inputing the value into the editbox or when he are done with the input and accepts (presses OK or Enter).
The latter one is easier, in OnOK() call a function which validates the entered value and if it returns true everything is ok and you can close the dialog else you need to pput up some error and let the user try again.
Validating during input is a bit trickier, but if you use a masked edit control it's not that hard. Microsoft has one, Insert ActiveX control - Microsoft Masked Edit Control (msmask32.ocx). I use one from Dundas, which they gave away for free a long time ago! It's a very small part of there Toolbox. You will find several attempts here on CodeProject also... http://www.codeproject.com/editctrl/#Masked%20and%20Validating%20controls[^]
Hope this will help you!

Hi
I added the OnPaint() function to my CDialog-based app via the class-wizard. But for some reason it does not get called, why? 
As far as I can see classwizard set up everyhting correctly:
afx_msg BOOL OnEraseBkgnd(CDC* pDC);
virtual BOOL OnInitDialog();
afx_msg void OnPaint();
ON_WM_ERASEBKGND()
ON_WM_PAINT()
void CMyDlg::OnPaint()
{
CPaintDC dc(this);
}
What's going wrong?
thanks in advance,
Greg

It all looks good to me.
did you include the obvious -- #include <afxwin.h> ?
That would be my only two cents

The code looks ok for a window but actually I think the dialog takes care of its painting in the background. Each control does it's own painting when necessary.

I am having trouble getting an embedded object to update in my view. I have embedded Excel in a CView. When I change items on the current worksheet, they change on my view just the way they are suppose to but if I issue a command to change worksheets my view does not show the newly active worksheet. If I open the object for editing in another window I can see that the active worksheet has actually change but it is not displayed on my view. If I change the active worksheet in Excel it does change in my view. I must me missing a command to update my view. Can someone help?
Thanks,
Tim

Hi,
I need to create in separate thread some dialog controlled by CDialog derived class. Thread will create the dialog, process user's actions on it and after closing od dialog, thread can terminate.
I tried to create thread by AfxBeginThread() - worker thread type and i created dialog and called DoModal() in controlling function. But after displaying the dialog it still acts like modal dialog, even if it is in separate thread - i can't click in main application dialog.
How to solve this ?
Thanks

It is surely better to do this with UI threads: Derive from CWinThread to, say CMyThread, override OnInitInstance and display the modal dialog there. To terminate the thread, just return FALSE from OnInitInstance.

I tried that, but it is doing the same thing :
class CMyThread : public CWinThread
{
DECLARE_DYNCREATE(CMyThread)
public:
...
BOOL CMyThread::InitInstance()
{
CMyDialog dlg;
dlg.DoModal();
return TRUE;
}
I made button in mail application dialog, which creates my thread. It displays modal dialog but i still can't access main application dialog until i close thread's dialog

Why not make your dialog modalless?

One of the properties of a modal dialog box is absolute focus from the parent window. For more flexibility, use a modeless dialog box another member has mentioned.

hi

There is a WordPad like sample in the Visual C++ Samples. (MSDN search should find it) This should give you a good starting point.

Hey all,
This is a bit of a stupid question and probably has an obvious answer, but ill ask anyways.
Ive created a Win32 project in .NET that outputs as a DLL. In it ive added 2 classes and put all my code in, and now i want to call it in either C# or MC++. Problem is, i dont know how to add it at all (in C# its under project->Add reference i think, but it keeps reporting that it cannot add it bcos its not a .NET assembly). Can anybody give a quick pointer ??
Thanks in advance

Well if you created a Win32 dll than that obviously is not an assembly - you need to create a .Net dll (which is an assembly essentially). Or use pInvoke to call the win32 dll from C#.

If I compile a code that uses MFC the size goes about 36KB. If i compile almost same code tht doesnt use MFC its size goes to 56KB.
How can I reduce the size of my exe file.
In my dream, I was dorwning my §orrow§
But my §orrow§, they learned to §wim
|
|

|

But the 36k is without the mfc dll. Trust me, in the end, a program with mfc is _much_ bigger than a plain C one

Hi!
I am writing a custom window control in MFC: a tab control.
CWnd
A
|
|
MyTab
class MyTab : protected CWnd {
public:
void add(const CString& title, CDialog* dlg);
...
protected:
...
private:
...
};
Everything goes well. Now I want to seperate interfaces from implementation theorically:
CWnd ITab (abstract class as interface)
A A
| /
| /
MyTab
class ITab {
public:
virtual void add(const CString& title, CDialog* dlg)=0;
};
class MyTab : public ITab, protected CWnd {
public:
virtual void add(const CString& title, CDialog* dlg);
...
protected:
...
private:
...
};
This time, the problem exist: there is no HWND attached.
Does anyone know how to solve this? Or is there an alternative design?
Any reply would be appreciated.
