Never use TerminateThread, this is a very bad approach. I suggest you read this article[^] from which you will learn a lot for threads. This is a long article but it's definitively worth reading it.

Thanx Cedric
Before using terminatethread, I used same logic which given into link but at that time I got run time exception on delete Cwin thread..
is there having another way to remove memory leak....
Can vld find out memory leak which occures due to thread termination.
Thank You For your reply...

First, do not use TerminateThread() to forcely terminate thread. The best way is let the thread terminate itself. If you want to terminate thread while thread is running, set a flag to notify the thread and let it self-terminate. Read the book "Multithreading Applications in Win32", a good book you need to read before you use multithread.
Second, you need to check your code to see where you dynamic created variable but not delete it upon thread exit. You need to check this yourself, no other people can help you.

Thanx for your reply... I will read that book.
And in my thread I just used local Variable, mydoc variable and my view variables...
|
|
|
|
|
even if you use local variables you'll end up with memory leaks if the thread is not properly shutdown... good luck!

Hi,
I am linking my app with a number of static libraries which contain dialog resources etc. Unfortuntately, some of the resource IDs appear to be conflicting. I could reallocate the resource IDs in the static libs to overcome this but is there a better way?
Thanks
Tony

The only IDs that must be unique are dialog IDDs, string IDSs, and menu IDs. The IDCs can be reused (between dialogs) and it won't matter.
To ensure that the dialog IDDs don't collide, you could switch to string resource names, instead of numeric resource IDs. To do this, simply comment out the IDD define in resource.h, and change the ctor of the dialog to use the string form. Also comment out the enum in the dialog header file.
Ideally, the resource.h file should be organized by dialog, so that each IDC is unique; sometimes this can get away from you. You might want to check into the excellent Resource ID Organiser Add-In for Visual C++ 5.0/6.0/.NET[^] as a way of restoring order to resource.h.

Hi Hans,
Thanks for the reply - that's a great idea!
Thanks again

Hans,
Sorry to trouble you again but I have changed the dialogs to use string resources and recompiled both the lib and the application which uses the lib. Everthing compiled OK but the dialog does not appear when DoModal() is called. I have trace through the MFC code for DoModal() and the call to FindResource() returns NULL, even though the resource name is correct.
If I compile the library as a DLL then the dialog appears OK.
I realise its hard to do things by remote control but do you have any thoughts as to what could be causing this problem, or what I could check?
Thanks
Tony

In your original message you said "I am linking my app with a number of static libraries which contain dialog resources". This is not possible. A static lib cannot have resources. A DLL (really an exe) can contain resources.

How to encode fabs with SSE assuming 4 floating points are already in __m128 register?
It is better to use SSE2 or 3 but alternatives for latest SSE will be also acknowledged

Resetting sign bit;
__declspec(align(16)) float arrFlt[4] = { -10.0, -20.0, -0.0, -3.0 };
__declspec(align(16)) int mask[4] = { 0x7fffffff, 0x7fffffff, 0x7fffffff, 0x7fffffff };
_asm lea eax, arrFlt
_asm movaps xmm0, xmmword ptr [eax]
_asm andps xmm0, xmmword ptr mask
_asm movaps xmmword ptr [eax], xmm0
Or with intrinsics;
_mm_store_ps(arrFlt, _mm_and_ps(_mm_load_ps(arrFlt), _mm_load_ps((float*)mask)));

Vista and above windows OS have an option to change display [see below image]
http://www.freeimagehosting.net/uploads/6704c49814.png[^]
If user select any thing else other than 100% then my application ui gets disturb. Background image does not cover the whole dialog and labels do not contain whole text.
Is there any way to fix that?
This is how my screen looks like
http://www.freeimagehosting.net/uploads/5e21dbde72.png[^]
It's background is white but it is not getting stretch to cover the whole uncovered space when I change the display. In normal case (100% is set) it look fine.
Any help ??

Actually this predates Vista; on the NT side, even Win 2000 let you change the font size (small fonts, large fonts).
What you need to do is first handle the WM_DISPLAYCHANGE message, which tells you that some display setting has changed. Then, you need to resize and reposition the controls and background image to fit properly with the new settings. See (as an example) CResizableDialog[^].

Hi ,
I have created a timer using ::SetTimer () and provided a TIMERPROC. This is working fine when I use ::GetMessage () , TranslateMessage () ,DispatchMessage in a Message Loop. I have not created this Timer for any specific window by providing NULL in first parameter to SetTimer ().
I have 3 threads and each thread will be having a Timer. Is it a good practice to use multiple message loop in an application. Wont they get messages of each other's message que.
