Thanks for your reply, I try with mulDiv(8,GetDeviceCaps,LOGPIXELY,72) to detrmine the size.
It's OK ,but I have another problem on dot matrix, the same line is printed twice in the same line in horizontal like:
------------------- -------------------
Why ?
I am using Lx 300
On deskjet and LAser no problem

How are you deciding where to print?
Again, if you're using MM_TEXT mode, you need to determine Y values correctly for line positioning. You can do this by determining the printing height of a single line, using GetTextMetrics(dc, &tm) where tm is a TEXTMETRIC structure. This will give you tm.tmHeight which is the line height, you may want to add tm.tmExternalLeading to space the lines out more. Or again, to print at positions relative to the page top, if you know the distance in say, inches, you can use MulDiv again to calculate Y values.
If you have
yInch = GetDeviceCaps(dc,LOGPIXELSY);
then 1.1" down would be
MulDiv(720+72, yInch, 720)

This all my code when I print.
With dot matrix printer I print only the first dc.TextOut but others are not printed.
With LAser or deskjet printer all is printed, no problem here.
What to do ? so to print on dot matrix what I need like:
CFont font;
font.CreateFont(-MulDiv (8, dc.GetDeviceCaps (LOGPIXELSY),72),0,0,0,FW_DONTCARE,FALSE,FALSE,0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH|FF_MODERN,"Courrier");
dc.SetMapMode(MM_TEXT);
CFont* pOldFont = (CFont*) dc.SelectObject(&font);;
dc.GetTextMetrics(&tm);
nHeight = tm.tmHeight + tm.tmExternalLeading ;
hauteur = nHeight; l += 1;
strCommand.Format("|%-50s","Matric." );
dc.TextOut(Info.m_rectDraw.left ,Info.m_rectDraw.top + (l * hauteur) , strCommand);
strCommand.Format("|%-80s","Nom" );
dc.TextOut(Info.m_rectDraw.left + 300 ,Info.m_rectDraw.top + (l * hauteur) , strCommand);
strCommand.Format("|%-50s","Postnom" );
dc.TextOut(Info.m_rectDraw.left + 900 ,Info.m_rectDraw.top + (l * hauteur) , strCommand);
strCommand.Format("|%-50s","Initial" );
dc.TextOut(Info.m_rectDraw.left + 2500 ,Info.m_rectDraw.top + (l * hauteur) , strCommand);
strCommand.Format("|%-50s","Nb.retenu" );
dc.TextOut(Info.m_rectDraw.left + 3000 ,Info.m_rectDraw.top + (l * hauteur) , strCommand);
strCommand.Format("|%-50s","Restant" );
dc.TextOut(Info.m_rectDraw.left + 3500 ,Info.m_rectDraw.top + (l * hauteur) , strCommand);

Hi all,
some time ago, i had to write a program which starts other executeables (i did this with CreateProcess). Not a single process started was depending on the termination of another started one. Since then, the requirements changed and i have to include the execution of processes which depend on the termination of other processes. as i am not a programmer in general, i have no idea how this could be done. could someone please guide me how to do this?
CreateProcess A.exe --> A.exe is working without a dependency
CreateProcess B.exe --> Should be started when A.exe terminates
CreateProcess C.exe --> Should be started when B.exe terminates
Thanks in advance,
nmx

U can use the handle returned by CreateProcess as a parameter to WaitForSingleObject(..).. This will make your process wait for the process to exit and then continue.
<br />
In ur scenario it will be,<br />
HANDLE hprocessa = CreateProcess("a.exe", .. other parameters);<br />
WaitForSingleObject( hprocessa, INFINITE );<br />
HANDLE hprocessb = CreateProcess("b.exe", .. other parameters);<br />
WaitForSingleObject( hprocessb, INFINITE );<br />
CreateProcess("c.exe", .. other parameters);<br />
Chao!

Ciao nutkase. Thanks for your answer.
This is exactly the way i do it right now, but this is way too unflexbile. Lets say I want to start another Process D while Process A is running. Process B and C are waiting for the termination of Process A. If I use WaitForSingleObject(A, INFINITE) on Process A, i won't be able to execute another process (Process D) at the same time.
What i think about is having Events for the termination of a process.
Greets, nmx

|

Well, its just the matter of syncronization now. U will have to make a compromise on flexibility at some point. Events is a gr8 idea. best of luck

Ok guys, i solved the problem using the processes HANDLE and PROCESS_INFORMATION
<br />
PROCESS_INFORMATION piProcessA;<br />
...<br />
DWORD dwExitCode;<br />
GetExitCodeProcess(piProcessA, &dwExitCode);<br />
while (dwExitCode == STILL_ACTIVE)<br />
{<br />
GetExitCodeProcess(process, &dwExitCode);<br />
Sleep(500);<br />
}<br />
Next challenge: How could it be done to have dynamic process dependencies. The configuration should be made in a header file (f.e. via #define)
There are a few processes: A,B,C and D
B depends on A and C --> #define B_DEPS "A,C"
Any ideas? 
Ciao, nmx

Hi,
I want minimize,maximize,close icon in child window.How can i do this?
I tried lot of things but failed.
The problem is..I got these icons in my child window, when i minimized it has gone somewhere, so i cudn't maximize the window again..and also when i click restoreup in that three icon(middle one) it didn't minimized to small size..nothing get changed but three icons will disappeared.
One morething these three icons didnot display when the application opens, when i switch to another window in the same application then come back to this window then the three icons appear,
What can i do?
My requiremnt is same as vc++ coding environment(i.e., we can minimize,close and maximize the text editor in our vc++ complier)I need the same functionality..Pls help me out?

hi all i had made application that send() recv() through winsock API's not the MFC classes and winsock controll.
when i send one time it works fine and receives well but when i send more than once at a time
i.e
if((send(conn,"11",strlen("13"),0))==2)<br />
AfxMessageBox("11");<br />
if((send(conn,"12",strlen("13"),0))==2)<br />
AfxMessageBox("11");<br />
if((send(conn,"13",strlen("13"),0))==2)<br />
AfxMessageBox("13");<br />
and then closing the sockets<br />
other side cannot receive anything i mean it receive 0 bytes.i m using the receive side in for loop here is the code.
for (int i=0;i<3;i++)<br />
{<br />
int numbytes;<br />
char buf[5];<br />
if((numbytes=recv(new_fd,buf,strlen(buf),0))==0)<br />
AfxMessageBox("Conn Forcefully Rejected Receive Error");<br />
else<br />
{<br />
buf[(numbytes+1)] = '\0';<br />
AfxMessageBox(buf);<br />
} <br />
}and then it closes sockets also.
but it shows the conn forefully rejected receive error.
i dont why it is this.

you just mention length '2'.
recv(new_fd,buf,strlen(buf),0)
instead use this
recv(new_fd,buf,2,0)
|

|
|
|
thanks it did worked.

It seems that you find your answer but see an article about transfer file with socket on codeproject maybe it helpful for you.
|
|
|
|
|
In my opinion there could be many reasons for this code not working. The most important and in my opinion the one with the brightest chances is the connection not properly set up. post the full code then may be anybody would be able to help!

Hello friends,
I have an appication of recording a wave file.
But i want to specify the sound device through which only
the wave file should be recorded. That is if my machine has more than one sound card
then i want to select one (through Programmatically) and record sound from that one only.
How to do that.
Thanks in Advance.

Hi,
I get the file size and I want to format it using the format (xxx,xxx,xxx), for example:
35456931 --> 35,456,931 bytes.
how can I do it??

Like this:
CString strNum="123467890";
int len=strNum.GetLength ();
for(int i=len-3;i>0;i-=3)
{
strNum.Insert (i,',');
}
AfxMessageBox (strNum);
Somethings seem HARD to do, until we know how to do them.

Here is some code that will format a number using the current locale settings:
std::string format(unsigned int n)
{
std::stringstream strm;
strm.imbue(std::locale(""));
strm << n;
return strm.str();
}
