Can anyone please explain me what is a call back function?
Is that function an API or is it something else?

Thanks

How to get process id given the process name

Hi,

From within my application i need to wait for an external process to complete before proceeding. But all i have is the external process's name. Is there any API that returns the process id or handle given the process name ?? I tried using CreateToolhelp32Snapshot but it does not seem to work in VC41 in which my application is built. It works fine in VC6 though.

Thanks for ur help.

You can not to get the Handle of the process from the process name, you need to do the contrary. You must to enum the process handles or Ids and the get the process name

You need to use the psapi.dll library.
You must to use the EnumProcessModules function and then the GetModuleFileNameEx function to get the filename of each process.

Problem with TextOut() in Windows 2003 Japanese?

RYU^^3-Feb-05 15:28

Hi MASTERs,

I am using CDC::TextOut() to display lines in the screen. Imagine that I want to display the following line:

1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789, [Put a double byte kanji character]
1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789, [Put a double byte kanji character]
1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,1234,6789,

If you run in Windows 2003 Japanese, you will see that the 3rd line is aligned properly on the screen but it is NOT aligned properly when you do printing or print preview (no matter which font you are using, the alignment always wrong).

Now, if I remove the comma, both printing and displaying works fine (aligned the line properly).

1234678912346789123467891234678912346789123467891234678912346789 [Put a double byte kanji character]
1234678912346789123467891234678912346789123467891234678912346789 [Put a double byte kanji character]
1234678912346789123467891234678912346789123467891234678912346789

It is only happening in Windows 2003 Japanese and Windows XP Japanese (I haven't check Chinese version yet, but I think it will have the same problem).

Any idea? Please help...

Thanks...

This Is Example for using the ShellExecute.let you want to open the Notepad.exe. so ShellExecute will be used this way....

::ShellExecute(NULL,//Using Windos Desktop a Parent
             "open",//Open Vern Means that we are 
                    //launching app
             "notepad.exe",//application name
             "",//No paramter
              NULL,//use Current Directory
              SW_SHOWNORMAL);//launch in normal way

correct way to determine control part dimensions

Jim Crafton3-Feb-05 14:16

Jim Crafton

3-Feb-05 14:16

Anyone know of a pixel perfect correct way to determine the width/height of various control parts, thqat takes into account the current font used for the control?
For example, what are the correct dimensions of the a standard check box or radio button?
What about the proper height for a combo box or push button?
GetSystemMetrics() only covers certain general things. Any other solutions? I have tried to create a function that works out the pixels given a value in dialog units and a font, but this doesn't seem quite right.

For example, if you wanted to create a custom control that gets used as a header, how would you accurately determine the default header height so it matches to what the header in the ListView control has?

Is there any chanse to link those dlls so their copying into the intro dir wouldn't be needed?

Grtz.

You have two options.

1. Don't use the c run time - use C++ functions.

2. Distribute the msvcrt dll

Also, NEVER distribute a debug build, so that no-one ever asks you for a debug DLL again.

Socket method advice?

z33z3-Feb-05 11:34

3-Feb-05 11:34

Hi!

I'm writing a program which needs to recieve a lot of data though a socket. Another application sends a lot of small portions (like 50 byte) of data (measurement data) to it over the network, like 1000 messages per second.

Which socket communication is the best/fastest? Right now I testet a blocking CSocket in its own thread, but that really slows down the machine. But how should I do instead? Any tip? Should I use CAsyncSocket instead, and how? Blocking or non blocking?

Thankful for any suggestion!!

Re: Socket method advice?

You should easily be able to achieve 30,000(or more) messages per second, provided you have good hardware and a fast network connection, using IO Completion Ports and asynchronous sockets.
