Ah, ok, my point back to gregor is that even if you implement operator ==, there is no magic, you still need to decide how your class is going to test for equality. And if your class has many memeber variables, you'll need to test all of them.

In my MFC dialog app I need tooltips for items in a CListCtrl. My implementation is similar to that in Matt Weagle's 'Using the List Control' tutorial. E.g. I'm handling the LVN_GETINFOTIP message with
void CMyDlg::OnInfoTip( NMHDR * pNMHDR, LRESULT * pResult )
{
NMLVGETINFOTIP * pInfoTip = reinterpret_cast<nmlvgetinfotip *=""> (pNMHDR) ;
_tcscpy( pInfoTip->pszText, _T("Some tooltip text") ) ;
}
The tooltips appear BEHIND the dialog box (so only the end of the tip shows past the end of the dialog)
Can anyone help?
Thanks
Monty

I had problem like this with treectrl in floating toolbar. You may try with this code - it makes tooltips the topmost window:
::SetWindowPos(
(HWND)m_yourListCtrl.SendMessage(LVM_GETTOOLTIPS),
HWND_TOPMOST,
0, 0, 0, 0,
SWP_NOMOVE | SWP_NOSIZE);
Note that you need to get listctrl tooltips using API - MFC doesn't have a wrapper for LVM_GETTOOLTIPS in VC6.

Thanks for your suggestion Tomasz.
It does bring the tooltip to the front, but when I move the cursor over a new item (without clicking on it), the tooltip vanishes for about 1 second (and the dialog box title shows that it is no longer the active window), and then it reappears OK.
Any suggestions gratefully received...

Adding the SWP_NOACTIVATE flag to the SetWindowPos call prevents this problem.
Thanks again for your help Tomasz.

how can i fill the testprintpage in VC++ ?anybody knows pl.. let me know about it with code

Hi,
I have created a class with CPropertyPage as its base.
I am then using the m_psp member to build a PROPSHEETPAGE structure which I pass to CreatePropertySheetPage function to create a property page I can add to a device's property pages.
The problem comes when in one of the routines for a button on my CPropertyPage I create an instance of a CDialog class I have and call DoModal()
The device manager crashes when this is run.
Any ideas why would be useful.
thanks

Hello!
I'm trying to create a MFC dll that makes use of MS WebBrowser activeX
component. Another application loads the library runtime and calls certain
function that creates a dialog box with an explorer control. When creating
the dialog box, however, the initialization of browser control fails,
reporting
CoCreateInstance of OLE control {8856F961-340A-11D0-A96B-00C04FD705A2}
failed.
>>> Result code: 0x800401f0
>>> Is the control is properly registered?
Warning: CreateDlgControls failed during dialog init.
In the dll initialization, I call AfxEnableControlContainer().
If I build an EXE that creates a simple dialog with explorer control, it
runs just fine, but if I try to use it in a DLL, things don't work out.
Any ideas how to make it work?

|
|
|

I'm not an MFC newbie and I'm still having the same exact problem with a different ActiveX control. I've been told that you also need to make a call to AfxOleInit() in the DLL initialization, but I've done that and it hasn't helped me a bit. Nobody so far has been able to help me solve this problem and it's really becoming frustrating. Let me know if you find a solution.

Hi Everybody
I need to create a CListCtrl of which one of the subitem is more than 300 characters - I found that the CListctrl by default limits its subitem's max lengh to around 260 characters. Even though i see the value in the debugger - it's truncatd when i view it on the screen. Any code would be of much help.
Thanks in advance.
regards
Sankar

I've seen the same problem and thought it was a bug in my code at first. It's pretty pathetic, really. 300 characters is not a sensible limit, if any limit is sensible in the first place.
Death to fixed-size buffers!

What is a good, relatively simple (and *free* preferably) program to create
patches with?
I had experimented with BinPatch for a little bit, but the one thing I don't
like about that is that it always creates backups on the users computer of
the file(s) it patches. In the docs for it, it said that in the next
version, there would be a way to set backup to none, but apparently there
never was a "next version". Also I would love to have a GUI interface for
the patch creator, but the one for download (www.binpatch.com) is
corrupted...
Does anybody else know of a good program I could use?
Thanks!

Try PCOM
All the crackers seem to use it.

I am learning C++, and I am trying to make globber (Sample on MSDN CD) and it draws a SDI window and all of its functions are LRESULT. I am trying to make it into a Dialog application for easier use but I keep getting errors. Does anyone know how I should go about converting this. Thanks in advance.

I'm working on a program that can work with both NT and Win9x. I finish the NT version first, then try it in Win9x. I found that after doing output awhile or moving the window around, the font change!!!! And also the system change too (all system dialog box font changes..).....and if I did something....Win9x asks me to terminate the program too....(this dialog font has been changed too)
Moreover, when I do drawing......after the font change.....no colour can be displayed....only black and white.
My question is....do i have to do anything when I migrate the NT program to win9x. Are they different?

That sounds like you have a severe leak that's eating up GDI resources. Win9x still has old Win 3.1 memory limitations, so that's why you see the problems on 9x.

Can you tell me what should I do??? Because i really have no idea how to fix the problem.
But thanks to telling me that.

You say you do drawing. Maybe you allocate some stuff, like CreateDC() and then forget to call DeleteDC(), this could also be with brushes, pens, bitmaps and...
If you do that kind of custom drawing, without releasing the resources you use, Win9x can run out of GDI resources pretty quick.

Hiya!
Is there a way to draw or write something on screen when another program, a game using opengl or directX for example, is running? If so, how?
Thanks in advance,

When using unicode, how to write double byte strings to text files without leaving a space between characters (WriteString of CStdioFile does not work in Embedded VC++)?
Also how to add new lines to the output file?

I have an SDI app which stores and retrieves its contents using serialization.
the app will only ever use one data document, so i want to hard code the open and save commands to save the user from using the menus and toolbar buttons.
I've tried using the OnOpenDocument command with limited success......my problem is essentialy that I don't know where to place the command so that it effectively prevents the automatic doc opening in the template construction.
A fairly basic question I know, but if someone could take the time to help it would be appreciated.

Try using OnOpenDocument("YourFilename.ext") in InitInstance. I'm not sure what to use in ExitInstance for the save though.
