Fixed it. In the parent dialog the OnSize handler was resizing the tab control fine the child dialogs were not resizing. I added a public function ResizePage() to the CMyTabCtrl class and called it in the parent OnSize handler as well as when a tab was selected. Now no matter what happens the child dialogs are resized to fit the tabs correctly.
Thanks for the help.

I am getting a crash inside InternetConnect and I can't for the life of me figure out why. It seems only to happen when I pass INTERNET_SERVICE_FTP -- I have a test program which does nothing but create a CInternetSession, then call GetHttpConnection, then call GetFtpConnection, passing valid IP addresses to both functions. GetHttpConnection returns successfully. GetFtpConnection crashes with an illegal memory access (and an overwritten stack) after the CFtpConnection constructor calls InternetConnect. Is there anything I can do to repair this short of reinstalling Windows? (The install is Windows 2000 sp 4.)

Hi,
I want write small a application which draw`s a graph,taking x-axis values from 300 to 900 and y-axis values from 0 to 100.I want to graph to smooth and linear.If any one already written any article on this issue please let me know.
Thank in before
James

All linear graphs of the form ax + by = 1 are smooth because they are differentiable at each point.
If you just want something approximate, be it a polynomial of degree 1 or higher, you might look into the Mathworld's Article on Least Suares Fitting[^].
Now, if you are talking about polynomial curve fitting, then you want to learn some numerical analysis. MIT's Open Courseware[^] has some good information on it.

do you mean programmatically, or as a user? I know in Word you can select any column by holding ALT while dragging your selection with the mouse

Hi all,
I wrote client-server applicaion communicating via socket. I met a big problem that I did not know which function can be use to indicate the buffer size will be received before calling function recv() or WSARecv().
I want to know this information to allocate the buffer enough to receive the message coming.
For example:
int bufSize;
/*Do which thing here to indicate buffer size bufSize = ???*/
char*buffer = new char[bufSize];
recv(hSOCKET,buffer,bufSize,0);
If we dont know this information before calling receiving function, the problem is we won't know how big the buffer size should is.
Although, we can do: char buffer[100000]; but the size of coming message can be bigger or the coming message is too smaller than that.
Any boddy know this problem, Can you help me?
Thanks very much & best regards,
Tin Le

Send the buffer size first, then send the actual data.

You do not need to know the buffer size before recieving the data, although it would help. C++ solves many problems like this by providing [classes like] the vector template class. What I am trying to say is that you can declare a vector to recieve the data, and just keep calling push_back(...) to stuff the bytes into the buffer. If you have a good idea of how many bytes of data you expect to recieve, then set the initial size to that many bytes (as an added safety measure you might double the number, but why waste memory). The reason you want to set a minimum (or maximum) for expected bytes of data, is that you want to avoid forcing the code to reallocate a new memory block that is large enough to hold all the data.
You can do the same thing in C, but C does not provide nice little pieces of code to do it for you.

how can i read a text file which is in client's system and print it at client's default printer.

Your question is a bit vague, so this is the best I can come up with:
ShellExecute(NULL, "print", "file.txt", ...);

Hello again.
This is Matthias form germany. I've a problem with my printer. For a few letters i've to get another tray on my printer but i've no idea how to do.
I post you my actually print initialisation:
[Code]
CPrintDialog dlgPrint(FALSE,PD_ALLPAGES,this);
if (dlgPrint.DoModal() == IDOK)
{
CDC pDC_print;
pDC_print.Attach(dlgPrint.GetPrinterDC());
DOCINFO myPrintJob;
myPrintJob.cbSize = sizeof(myPrintJob);
myPrintJob.lpszDocName = "test";
myPrintJob.lpszOutput = NULL;
myPrintJob.lpszDatatype = NULL;
myPrintJob.fwType = NULL;
......
}
but how can I set the tray, that the user hasn't to choose it in the printDialog?

Did you try changing the dmDefaultSource in the DEVMODE and then try?

|

yes, of course.
the problem is, that the initialisation is before i set the new flag to DEVMODE structure.
CPrintDialog prtDlg(FALS......)
if ( prtDlg.DoModal() == IDOK )
{
prtDlg.m_pd.dmDeviceSource = 2;
......
}
the flag in the structure was set but he takes the normal default paperSource

You got to set the DEVMODE in CPrintDialog before you call DoModal(...) making a call afterwards will not work.

This was what I already found myself on the msdn site. But it is not a very complete example, is it?
It is somewhat the only example I was able to find on the Internet.
But thanks anyway,
Ward

Yeah it is complete with the one that I didn't paste. Search in MSDN documentation for the other one.
The search is titled "Using toolbar controls".
It has got a comprehensive coverage of what you want. I just pasted the interesting(for me) part.
