This unusual selection highlight is one of our customer requirement. Anyway As you suggested I tried the OWNER DRAW way and it works.

Thanks To Tom, Giorgi and Gary

I would suggest doing it the "custom draw" way instead. All you have to do is set a color then. With owner draw, you have to draw the entire thing if I remember correctly.

Custom Draw = listen to NM_CUSTOMDRAW (or something like that)

That's true and in my VC++.NET Bible I actually cover custom drawn controls as opposed to owner drawn controls. However, I figured that he'd find more owner-drawn code and more easly be able to plug that into his project.

memory leak question

Chaoslord3-Jun-05 18:53

3-Jun-05 18:53

I have a program that I have access to the code for. This program runs over a period of time and memory slowly goes up. This could be because of a memory leak or memory just bad memory management. Is there a way to let the program run for a while and then try to dump the memory to see how it is being used. What is the best way and quickest way of detecting where the memory is being used but not being freed? I know in programming Lotus Domino from the C API you can put a few parameters in the notes.ini after viewing a memory dump and determine exactly where a memory leak is occurring. Is there a way to do this in a C++ application or even tools that just run along side a program that monitors the leaking program.

Thanks

If you can run a debug build, you can use the CRT memory dump system to help track down memory leaks. Lookup _CrtMemDumpStatistics or one of the other _Crt memory routines.

I'm going to patent thought. I have yet to see any prior art.

Thank you, I have been doing some reading on samples that people have posted using this and I have found some other articles as well. This looks like what I needed.

multithreading

Chaoslord3-Jun-05 18:43

3-Jun-05 18:43

I have worked with a couple samples in trying to figure out the best practices of multithreading applications. Most of these samples use threads that are only ran for short periods of times. What I would like to do is write a program that spawns off 4 threads. These 4 threads stay dormant or suspended until I send them a file to work with. Then they become active and go to work. When they are done, they should report back to the main application thread.

Where should I start looking for information on how to do this? Does anyone know of a good book that has good samples on how to do this? Do you know of an example on here that works this way?

Thanks

I created a project: HomeWork with a document-view.
This is a static function:
Header:
static DWORD __stdcall Thread(LPVOID lp);

Implementation:
DWORD __stdcall CHomeWorkView::Thread(LPVOID lp)
{
CHomeWorkView* parent = (CHomeWorkView*)lp;
parent->Work();
return 0;
}

A member variable is also there:
HANDLE m_hEvent;

A public member function of the class:
Header:
void Work();

Implementation:
void CHomeWorkView::Work()
{
while (TRUE)
{
if (WaitForSingleObject(m_hEvent,INFINITE) == WAIT_OBJECT_0)
{
MessageBox("Working on the file right now");
}
}
}

OnBtnStart:

DWORD id;
m_hEvent = CreateEvent(NULL,FALSE,FALSE,NULL);
CreateThread(NULL,0,Thread,this,0,&id);

When you want to start the work:
PulseEvent(m_hEvent);
------------------------
This is this's style of working with worker threads, kinda.
Just make it four threads, like Thread1, 2, 3, 4 etc. and four worker funcs like Work1, 2, 3, 4.
If you don't like this's style, then look somewhere else.

this is this.
