Hello, brother/friends in this codeproject.com forum.
first, My Name is Pardi Banjarnahor, I come from Indonesia.
as an information, my background aducation is in electronics.
the matter is I have a plan to make a program (software) that make possible for chatting (a client server application). May be it is like a SIMPLE yahoo messenger.
May questions are:
1. what kind of compiler (software) that is better, off course easy (simple) to make that sofware ( a client-server application).
2. it's possible to create/program it using MFC in Visual C++ 6.0?
3. I'm still a beginner in C++ programming, but I'm longing to be a good programmer in C++. If any one of you have information or advise (suggestion), It'll be very useful for me. if it's possible for you, you can e-mail me through Pardi.Marbun@gmail.com
Thanks for your attention and help.
Best Regards,
Thanks and GBU

There are several articles on client/server chat systems on this[^] CP page.

Aside from the obvious answer of, "With your eyes," can you be a bit more specific about what you want?

hi i am having a function named FinalCall() which in turn call some functions. i have to do thread for this in mfc. i tried
void CBootLoader1Dlg::OnYes()
{
AfxBeginThread(ComputeThreadProc,phObjectHandle);
//FinalCall();
}
UINT CBootLoader1Dlg::ComputeThreadProc(LPVOID pParam)
{
HWND *phObjectHandle = static_cast<hwnd *="">(pParam);
::PostMessage(*phObjectHandle, WM_UPDATE_CONTROL, 0, 0);
return 0;
}
LRESULT CBootLoader1Dlg::PaintText(char* lParam)
{
FinalCall();
return 0;
}
there is no errors . but i cant acheive the threading.
can any one explain this
thanx in advance

You didn't post the code in which you started the new thread. Can you post it ?
And what is the problem exactly ?
|
|
|
|
|
yes i posted it as ON_MESSAGE(WM_UPDATE_CONTROL,PaintText).

Ok, you updated your post.
The problem is that when you post a message, you will post it in the message queue associated with the thread that created the window (see here[^] ). So, the message will still be processed by your GUI thread (from any thread you sent it).
Why don't you call the FinalCall function directly there instead of posting a message ?
|
|
|
|
|
Again, you havn't stated your problem exactlty.

What does this mean, thread procedure is not getting called ?

i want to write very large numbers for ex 61118792 to the serial port.so i want to use DWORD to write data instead of byte.
When i take byte as parameter when using writeFile & ReadFile(and pass small values) i am able to get correct output,but if take parameter as DWORD i am getting some garbage value.
Please do reply how to solve this, if any other way also please suggest.

Can you show code ? causing this.
|
|

This is the code i found from codeguru.
The URL is as below
www.codeguru.com/Cpp/I-N/network/serialcommunications/article.php/c5395
please do take some time to look at the code

Doesn't Cedric's answer satisfy your query ?

Are you talking about this function ?
BOOL CSerialPort::WriteByte(BYTE bybyte)
{
iBytesWritten=0;
if(WriteFile(hComm,&bybyte,1,&iBytesWritten,NULL)==0)
return false;
else return true;
}
If you want to use DWORD, you need to modify it to,
BOOL CSerialPort::WriteByte(DWORD dWord)
{
iBytesWritten=0;
if(WriteFile(hComm,&dWord,sizeof(DWORD),&iBytesWritten,NULL)==0)
return false;
else return true;
}

Corrected typo.

Well, that's a solution but it is not very convenient to modify the function so that it can support everything you want to transmit  .
I looked at the article but I don't really see the added value of it. Yes, of course, it is perfect when you want to send bytes but when you have more complex datatypes then it becomes a pain in the sense that you need to use masks and bit shifting

thanks for Prasad& you for looking at the article.I understood what u both meant and modified but even then when i am reading back the value in that edit box i am getting garbage value.
can anyone please suggest me any other method when i want to send very large values that too many values if possible in an array accepting from different edit boxes.
|
|
|
|
|
Well, if you modified the code accordingly to what prasad said, you need of course to do the same for the Read function (so that it can read DWORD and not bytes).
|
|
|
|

Actually, I dont wanted to read the article, as it was to much for me to read whole article, because OP dont want to paste relevent code.
So I looked in to WriteFile part of article and give him suggestion.
|
|
|
|
|
Yes sure the same for me. In fact the post was not intended as a 'rant' to you but more to the article itself. That's not very flexible to only be able to send bytes. It would have been much more convenient to be able to send a buffer (if the buffer size is 1, then you only send one byte).
|
|
|
|
|
To write data to a serial port, you provide tha address of a buffer and the size of data to transmit. So if you want to send your DWORD, you simply need to do this:
DWORD dwMydata = 61118792;
WriteFile(...., &dwMyData, sizeof(DWORD), ....);
