I don't see any problems with the code at a quick glance - it all looks like classic Win32 stuff. If it worked on NT3.51, it should be fine and dandy under XP.

I'd create a Hello World windows (no MFC) project, and just start chucking the code in there.

Alternatively, read the excellent serial primer by Flounder, and make your own code using that as a serial core.

Hi All,
When I clickoon system tray icon first time menu works fine , but second time I am getting error like this ;

"Debug assertion failed!
Program: ...
File: F:\rtm\vctools\vc7libs\ship\atlmfc\winmenu.cpp
line 84
retry abort "

code is goes like:

LRESULT CDialogOnTopDlg::onTrayNotify(WPARAM wParam,LPARAM lParam)
{
UINT uMsg = (UINT) lParam;
switch (uMsg )
{
case WM_RBUTTONDOWN:
m_TrayMenu.LoadMenu(IDR_MENU1); // second time crashing here
CPoint pt;
GetCursorPos(&pt);
m_TrayMenu.GetSubMenu(0)->TrackPopupMenu(0,pt.x,pt.y,this);
break;
}
return TRUE;
}

Plz tell me wot could be possible causes.

My guess would be that you already have that menu loaded and you try to load it again using the same CMenu, either load it once or delete/destroy it before you try to load it again.

Well, i think you can do generally 2 things:
1. Load your menu only once and keep it around until your program exits (for example you can load it in the OnInitDialog of your dialog)
2. Load, use and destroy it "on sight", for example, you can use TrackPopupMenuEx[^] with TPM_RETURNCMD, if you do this, when the TrackPopupMenuEx call finishes you will get the command back from the call telling you what the user clicked on (or 0 if he dismissed the menu) and then you can use DestroyMenu[^] to destroy it. Of course doing so you will no longer need your CMenu to hang around so you can make it a local variable and then it will destroy the menu in its destructor when your method exits.

Judging by what i have seen of your code i guess for you the first aproach could be better.

I'm certain code-o-mat is correct in his answer to you.

But you really should have used the debugger to see the actual ASSERT line - that will give you lots of information you need to fix your own problem. I/we don;t mind helping - but you are much better learning debugging skills to find the issue out your self.

I bet the ASSERT line was something like:

BOOL CMenu::LoadMenu (UINT nBlah)
{
   ASSERT (m_hMenu == NULL); // check we're not already loaded.

which would have told you what your problem was.

And that's more than half the battle of solving the problem.

Make m_TrayMenu local to the OnTrayNotify() method.

I am using MFC picture control for displaying bmps on property dialog boxes. So I added picture contrl from the tools and changed the type to bitmap. Then selected a bmp resource to be loaded into the control. At design time the bmp is visible but at run time its not. I have done this before but the project used a MBCS. Now its Unicode.
Does that matter? If not what might be the problem?

TIA

Did you change from MBCS to Unicode in the same project? If yes, try cleaning and rebuilding the whole project if you did not try it yet.

But I added a new dialog, placed a picture control on it and loaded a bmp. It works fine in unicode also. I think it should not be specific to property sheets.
what do you say ?

Hi,

Cant you help me?
what is the command for c++ if i want to read the line but with the condition.
if LINE contains "my" copy the whole LINE.

myData.txt

1. Hello my dear!
2. Good day!

when i access the myData.txt the first line is "Hello my dear!"

i want to copy the line if contains "my" .

thanks

Common sense says:

Read a line (exit on 'no-more-lines' condition).
Search for "my" inside the read string.
Copy the line if the search of point (2) was succesful.
Goto point (1).

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

If you're using MFC, the CString::Find method [^] is the proper 'command'.

Along with the link given by CPallini, you can have a look at this[^] for reference if you aren't using MFC.

There is no single command to do this. It will all depend on what type of variable you are reading the line of text into (e.g, CString, string, char).
