so, I wrote a own TabCtrl were I use DrawItem and so on an there I recalculate the item's position. I guess this is the one an only possibility if someone wants to add dynamically contents to a tabctrl.
if someone has a better idea please let me know...
thanks

Bit Lengthy pls spare time
Hello All,
Let me tell you the problem clearly.We have a third party Dialog Dll which is loaded into the current application process when we choose a menu item called "Insert Dialog".Now when the user clicks File|Exit the application used to crash telling that unhandled exception in the Dialog Dll.Since its a third party Dll we dont have the source code.
So the solution i have hit upon to avoid the crash is that when the user tries to close the application you check whether that dialog Editor is open through FindWindow and if so ask the user to close the dialog before the File exit.This is working absolutely fine and its not crashing.
But the new Problem is with FindWindow.If there is another instance of the application and in that too if a dialog is open and even though the dialog is closed in the current application FindWindow keeps telling Pls close the dialog before the exit(This is because its finding that dialog window is open in the other application)
Now my doubt is how to force the FindWindow to seach in the current instance of the application only and not in others???
Thanks a lot for the patient hearing..
Hope i get the solution.
Luv,
pradeep

Use EnumWindows, for each window check the class/caption and process id (with GetWindowThreadProcessId).

Thanks for the reply Tomasz.But i could not get what you are telling.Some code snippet would really really help me.Expecting your mail.

1) use EnumWindows to enumerate all toplevel windows
2) for each window, check its class/caption.
3) if this is 3rd party dialog, you need to check if it's part of your application, or maybe another instance created this window
4) GetWindowThreadProcessId returns the process id given HWND. If your process id retrieved by GetCurrentProcessId is equal to HWND's process id, then this is your dialog.

Hi all,
I have a very general question about OpenGL. All the OpenGL examples that I have seen, which involves some rotation or transformation always take 100% of the CPU time! Is this because of the message pump or there is some other reason behind it? is it possible to circumvent this??
Thanks,
Pankaj

All opengl interative applications are trying to draw as many frames as possible. Taking up 100% CPU is quite normal for graphics intensive apps using either Opengl or DirectX.
If you're worried that some other apps or threads in the same Opengl app are not getting enough time slices insert a Sleep(0) after drawing doing a glSwapBuffer() call. This will give the rest of the time slice to any other thread which needs it.

Yes, just as what Briane has said, most of the OpenGL example is written for Win32, and the DrawGLWindow is called when there is no message waiting in the message queue. That's why it's taking up 100% CPU.
If you are developing a game, it's usual to have a Sleep(xxx) after the DrawGLWindow is called, so that you have a constant display update frequency.

How can I determine the horizontal/vertical spacing between characters?
The real deal is:
Is there some other GDI beside GetTextExtent() that can calculate text size? GetTextExtent() wont calculate the '\n' char...

DrawText with DT_CALCRECT will do. I'm assuming you want to get the height of multi-line text.

Does anybody know how?
I've looked in registry but not successful.
Do I need to use some network protocol (snmp, ..)?
Thanks,

If you're using W2000 or XP, you can use the DnsQuery API from the Platform SDK.
DNS_STATUS WINAPI DnsQuery (<br />
LPSTR lpstrName,<br />
WORD wType,<br />
DWORD fOptions,<br />
PIP4_ARRAY aipServers,<br />
PDNS_RECORD *ppQueryResultsSet,<br />
PVOID *pReserved <br />
);
Specify DNS_TYPE_WINS as wType. Never tried that but it should work  The ppQueryResultsSet contains DNS_WINS_DATA structures.

At last solution you could execute "ipconfig /all", catch the output and parse it. Of course, I also would prefer a nice API call, but if you fail to find something, this may be an easy and pragmatic solution.

Thanks, I've considered this solution.
But the problem is that I can't run ipconfig without opening its console window (or, if I can, how?).
This is real project for customer, not only for my home usage.

Hi,
I have a View which background colour is black, but when I use TextOut to display some texts on that view. There have a white box wrapped the text, So, I want to ask how to make the white box transparent/disappear. (i.e.It just display the text only.) Thx!!!

dc.SetBkMode(TRANSPARENT);

you can use ExtTextOut with nOption=ETO_OPAQUE and SetBkColor(RGB(0, 0, 0)) before it
