Thanks Paresh,
I suspect there is no implementation from Microsoft of CreateDirectoryA on Windows CE platform.

This is because you do not have Unicode defined.

Yes David,
I have not defined UNICODE. But if I do not define UNICODE, CreateDirectoryA should be linked. Why there is unresolved symbol error? Microsoft does not have the implementation for CreateDirectoryA for Windows CE?

George

Hi,
I would really appreciate if anyone could help me with a project in which I want to write code for encoder. Can you guys help that what do I need for it?
I will be very much helped.

I want to know what do I need for starting up this project. If you guys can give me your ideas, all will be very much appreciated.
Thanks again

start with IPO: Input, Process, Output.
what do you want to encode?
how do you want to encode it?
what purpose do you want the output to fulfill?
encoding is changing one thing to another:
compression is a form of encoding to save space.
ecryption is a form of encoding to hide the output from undesirables.
serialization is a form of encoding to transfer a binary object as text
etc.
So simply asking for help in encoding, help me now, please, won't get you far. Start by defining the problem, define it well. Once you can define it, you start breaking it down to its parts. IPO is an archaic method, but it still works especially for new programmers. Break it down into sub groups of functional parts, each with an IPO definition, each does only their small part. Put it all together, and you have a program.
BUT, first you have to start by defining it.

Thanks for such an inspirational answer. I really appreciate it.
I want to encode a video using Visual Studio C++. I want to get a compressed video as an output.
How do I start breaking it in parts? Do you mean should I start writing what I need to input, then process and then finally output?
I really appreciate the help.Thanks very much.

have you got the video to input? if not, you start there, how do you get the video.
Once you have everything needed to get the video into the design, then you need to compress it.
Do you want industry standard compression? do you want to use 3rd party libraries to do the compression for you? do you want to write your own compression? Is it for archival? Is it for streaming videos across the network? do you need high compression over low-latency? The questions just keep adding up. You answer them, figure out what you need to do that and move on to the next.
Are you writing the display? DirectX? OpenGL? (someone else here is doing video to texture -- you two might help each other).
there are libraries to do video compression, but that may not be what you need.

Your question is a little vague; an encoder of what?

I have made a dialog based MFC app but found a big problem. If someone is entering values into the edit boxes and then hits enter it closes the program. If you hit enter at all while the program is running and in focus it will end the program. How can I fix this?
Thanks

You can override OnOK() (and possibly OnCancel()) and in your overridden method,
do nothing.

Hi I cannot find those functions anywhere. I have this
CDLIADlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
return FALSE;
Brings up the main dialog, but I can't find the OnOk or OnCancel in the main dialog
|
|
|
|
|
They are virtual functions declared in the CDialog class. You can
add them through the class properties window or add them by hand
virtual void OnOK();
virtual void OnCancel();
...
void CDLIADlg::OnOK()
{
}
void CDLIADlg::OnCancel()
{
}Mark

Since noone else has replied...
Your code as shown compiles for me (if I add the missing semicolon
and comment out the "[..]") with no errors/warnings.

Hmm since I copied the code and compiled it, I can only assume your'e not
