yes, it term of syntax, what he does is correct, that's why his program crashed at runtime, not at compile time.
but the function is a C function (win32 API, no ?), so i doubt it would deal with C++ classes

You are not mixing an exe built in debug and a DLL built in release mode, are you?

No i am pretty sure that the two are in debug

Hi all,
If one creates a process in a thread, and that thread ends, would the process end aswell?
Thanx Again

an application have at least one thread, and if you don't create additional threads, you still run in the main thread.
so, when ShellExecute()-ing something in a single-threaded application, does it end when your own app exits ? no 
|
|
|
|
|
O.k so you create more threads, and one of those threads starts a process. So if I understand you correctly, the process won't die if the thread does? If this is the case thank you for the help toxcct.

not always several threads, but yes, no risk

Wrong usage. Threads are created within the process.
Programm3r wrote: and that thread ends, would the process end aswell?
Again. But yes, all threads end "abnormally" when the process exits without closing it's worker threads properly leading to crashes.

Thank you for clearing that one up, I thought it would be a good question to ask, was a bit uncertain about the whole thing....

yes, but executing code is always within a thread (even if the application is single-threaded), so when you create another process, it is always from a thread

Nope Toxcct. It runs outside of the process's(or a thread that created the new process) boundary.
Processes have their own boundary. So closing the thread would never affect a process created by it.

The question was about creating a process within a thread, not whether the newly created process will run within the same thread in which it was created.

 Yup I got the question wrong. Thanks for the reply

Hello! For couple of weeks I still have a problem with transparent buttons on toolbar. Toolbar background is 24bit image, buttons are also 24bit, VS2003, WinXP.
What I do (background):
1) Load standard 24bit BMP to CBitmap object
2) Create pattern brush based on bitmap from 1)
3) Use FillRect() inside OnEraseBkgnd().
Background is ok, drawing works fine.
Now the buttons:
Solution A:
1) Load 24bit BMP to CBitmap
2) Create CImageList based on 1) using ILC_COLOR32|ILC_MASK
3) Create mask by Add() function with proper RGB() transparent color
4) Use SetImageList() in toolbar control object
RESULT -> NO transparency (round buttons have plain color in the transparent color spots)
Solution B:
1) Load 24bit PNG with transparency to CImage
2) Create CBitmap based on (HBITMAP) operator from 1)
3) Continue steps 2-4 from Solution 1
RESULT -> NO transparency
Solution C:
1) Use CImage like in Solution B but use directly SetBitmap() from CToolbar
RESULT -> again no transparency.
Is there any simple way to get it working?? Basicly I want to have transparent bitmap on buttons. That means, I want to see bankground texture in the 'holes' in buttons (where the button's color == transparent color)
Please, enlighten me I've read many articles and found one solution but it was quite complicated and used many derived classes... ("BitmapToolBarResrch_en" project)
Solution can be Win2k/XP+ for MFC.
Thank a lot!!

there's a classic KB article (#79212) that gives the steps for a transparent Blt. but, it looks like MS has lost it.
but, Google knows where to find it.

Thanks for reply I've read this article... It means, I have to override WM_PAINT message and blit buttons by myself? Is there any way to 'prepare' somehow my bitmaps that Windows could draw them with transparency by its own routines, like it does for non-transparent toolbar buttons???
Ok, let's assume using WM_PAINT message, now I dont need WM_ERASEBKGND handler and should draw background and buttons in a single OnPaint handler?
Thanks again

yep. but you'd have to do that for a button with any kind of image.
you can use icons, which have built-in transparency, if you want to simplify things. but you still have to handle OnPaint.

not with any built-in classes.
but, there are dozens of bitmap button classes out there (a few really good ones here on CP). ex. : i like this one.

Hi,
I have used the below function to get the IP address of an PC by giving
the PC name in strFullName;
struct hostent *host = = gethostbyname(strFullName)
Is there any api function to get an PC name by giving its IP Address.

See if gethostbyaddr() which is a deprecated API helps. Alternatively see for getnameinfo()
Somethings seem HARD to do, until we know how to do them.
