In a CDialog I place and draw some controls, like buttons
by hands coordinating them in usual pixels.
With change of system font proportions of CDialog position and size of native CDialog controls changes not proportionally to
pixels... So Proportionality in sizes looses.
So Question is:
Which functions help to translate pixel coordinates
with system font change ?
thanks you

I need to play two *.WAV files at the same time in my application - as in solitaire games - the first file is the background music and second sound file is played when the cards are moved (or similar events). Any idea how to do this? I'm trying with PlaySound() and a new thread, but nothing is happenning - maybe I can't set the flags properly or there is something else?

|

void StartPlayTwoSounds()
{
PlaySound("MyFirstSound.wav", NULL, SND_FILENAME | SND_ASYNC);
PlaySound("MySecondSound.wav", NULL, SND_FILENAME | SND_ASYNC);
}

It doesn't work man
In that order only second file is played, but not the first!

well guys i am tired of using CSocket and CAsyncSocket buggy MFC sockets classes.
It was biggest mistake i did when i started two huge projects using these classes .now these projects are complete but the problem is , it is giving satisfactory results but not really good(Normally after some communication CSocket becomes useless , so i have to close it and again establishing connection and it is due to buggy message pumping mechanism of these sockets)
so if any have some good implemention of WINSOCK , specially a class which could handle the event notification like OnRecieve , OnCLose as in CSocket , and almost the same public initerface as CSocket etc.
It will make it possible to streight away replace CSocket with new one and no change in my existing projects .
If some body could refer some tested code in this regard , i 'll be really thankfull to him.
No Worries!

How familiar with Winsock are you? I prefer writing your own class from scratch and implement the features you want and nothing else.
I'm doing this right now for a project in school.
But you can always try google

 well, there is a CSocket class in the Visual C++ library, and i thought you did watched it...
emm, for my name, it means The Toxic Dream, but that was too long to write so here is the "condensed shape"... 
a last thing, excuse me for my very poor english, i do my best, but when you're french... it's not easy . I hope you understand me anyway... i think so

In my experience, as far as client side is concerned, CSocket/ASyncSocket should never cause any trouble. Though i personally prefer CAsyncSocket over CSocket, to avoid blocking issues. As such CAsyncSocket requires special care[^].
If we talk about server side, it depends upon the scalability desired (i.e the maximum number of users you want to simultaneously connect) and throughput (Data flow rate into and out of server). If both the attributes are low CAysncSocket should work fine. Otherwise you may need to dig into WinSock API and I/O completion ports.

first of all i want to brief u about my project.
It is a Video streaming software , so almost 5 tp 20 k data is sent across sockets per sec.For this i am using sockets with CSocketFile and CArchive attatched to CSocket object that is why i cant use CAsyncSocket .
what happens that after on average 10 to 15 frames , data socket becomes usless in a sense that even server sends me data but on client side OnRecieve does not calls . and on server end Send does not returns any error code.so what happens in this condition i close socket and reconnect with server , although i do it transparent from user , but surely a kinda delay comes.
So now my question is it due to CSocket , blocking nature (although i can use CAsynSocket cauz i am doing synchronize communication) but due to CSocketFile and CArchive i am using it.
No Worries!

Hi, Im using the FindWindow() function to find an application called Fullscreen.exe and then sending a WM_CLOSE call to it. However I get this error:
nPOSDlg.cpp(367) : error C2440: '=' : cannot convert from 'class CWnd *' to 'struct HWND__ *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
nPOSDlg.cpp(374) : error C2660: 'SendMessageA' : function does not take 4 parameters
This is the code that I have put into my OnAppExit(); because I want it to kill Fullscreen.exe when nPOSdlg closes.
HWND hWnd;<br />
hWnd = FindWindow(NULL, TEXT("Fullscreen"));<br />
if(hWnd == NULL)<br />
{<br />
}<br />
else<br />
{<br />
SendMessage(hWnd, WM_CLOSE, 0, 0);<br />
}
How do I convert from CWnd to HWND or what do I need to do?
Please help, thanks!

to keep things simple, just add :: before the FindWindow function, this will let you expelicitly use the HWND version.

Hi.
Can i know the return value of ReadFile when a timeout occurs, if the commtimeout structure was previously set?
I am writing a simple program that reads the serial port for characters arriving. Anyone can recommend a better option than the one i use?
Target device is WindowCE, using embedded Visual C++ 3.0
bool WaitForChar(unsigned char character,DWORD dwTimeout)
{
DWORD dwTimeStart,dwRead;
BYTE in[2];
dwTimeStart = GetTickCount();
while((GetTickCount() - dwTimeStart) < dwTimeout)
{
if(ReadFile(hPort,in,1,&dwRead,NULL))
{
if(dwRead != 0)
{
if(in == character)
return TRUE;
}
}
else
return FALSE;
}
return FALSE;
}

Hi...
What's the command to close a parent property sheet so that it's child pages are closed automatically also?
Thank you.

EndDialog() perhaps.

can you give example about implementing webserver using cgi
platform:windows2000
i've already try passing query_string using environment variable. i try it on command prompt. i use "set" command then query_string and variable name and its content.
then using syntax c:\php\php [php file where i wrote the script to display a $name variable] <[file location where i wantto redirect].
but i cannot do the same thing when i try to passing form data (POST method).
i've used command line winCGI-exe cgi-data-file. winCGI-exe is the complete file path to CGI prog exe like c:\php\php.exe
i've also completing cgi-data-file content.
it's consist of some sections like [CGI] section, [Form External] section,etc.
in [CGI] section i've wrote all the keywords like Request Protocol,Executable Path,etc. But again, it doesn't work. until once i met a line "input file not spesified" in command line of DOS after some http header,...PLZ help me!!!
NOTES: i found all the CGI specification on website with "Windows CGI Interface" keyword.
one of the author is Ken.Coar@Golux.Com and rdenny@dc3.com

I wrote an VC++ v6 MFC app that works fine when linked with the "Debug" version of MFC. However when I compile in the "Release" mode, the app crashes. I think I narrowed the problem to a worker thread posting a message to a window thread (by calling PostMessage()). I recreated the problem in a small MFC project, parts of which are listed below (I can also provide the project files if anyone is interested). In the debug version of the program, the worker thread continually sends an WM_APP message with one parameter to a CDialog-based window which displays the running counter. In the Release version, the counter stops at "2" then crashes. I'm running on XP Pro, but I also had the problem in Win98.
I'm stumped

The prototype for OnUser() is wrong, and you're ending up with a corrupted stack. It must be
LRESULT CTestMFCDlg::OnUser ( WPARAM wParam, LPARAM lParam ); See the docs for ON_MESSAGE for more details.

That did it. Thanks Mike.
I wish the debug version of MFC was less forgiving so I could have found it sooner.

Hey
I need to know how to display the system date and time in a static control in format: Day, Date, Time, AM/PM. Can someone please help me, this is a fundamental aspect to my program.
Thankyou
Ashman

have a look at strtime and strdate and related functions to create a formated string of a time and a date.
and to put it on the dialog, create a CStatic and use SetWindowText.

you can do this like that :
CTime t1;
t1=CTime::GetCurrentTime();
((CStatic*)GetDlgItem(YOUR_STATIC_ID))->SetWindowText((LPCTSTR)t1.Format("%H:%M:%S"));
that would be running...
