Dear Friends,
I am using CAsyncSocket and CSocket for writting a server program. In AsyncSocket I am using
virtual void OnAccept(int nErrorCode);
virtual void OnClose(int nErrorCode);
virtual void OnReceive(int nErrorCode); and also in Socket I am using
virtual void OnAccept(int nErrorCode);
virtual void OnClose(int nErrorCode);
virtual void OnConnect(int nErrorCode);
virtual void OnReceive(int nErrorCode);
Also in the dlg.cpp file,
At InitDialog I am writting
m_cSocketServer.Create(4000);
m_cSocketServer.Listen();
m_cAsyncSocketServer.Create(4000);
m_cSocketServer.Listen();
Also at the Onbutton message I am checking and writting a message into a display like this
void CMFCServerDlg::OnButtonConnection()
{
// TODO: この位置にコントロール通知ハンドラ用のコードを追加してください
char DispBuf[256];
if(m_cSocketServer.Create(4000) && m_cSocketServer.Listen()){
sprintf(DispBuf, "Server Started");
AfxGetMainWnd()->GetDlgItem(IDC_STATIC)->SetWindowText(DispBuf);
}
else{
sprintf(DispBuf, "Connection Failed");
AfxGetMainWnd()->GetDlgItem(IDC_STATIC)->SetWindowText(DispBuf);
}
For other reference....
LRESULT CMFCServerDlg::OnAccept(WPARAM wParam, LPARAM lParam)
{
m_cSocketServer.Accept(m_cAsyncSocketServer);
DestroyFlag = TRUE;
return 0;
}
This is a user message send by the AsyncSocket and Socket from OnAcceptMessage....
My applicaion is very simple and with the above code it is not working. Will you please help to detect the error. Why this code is not suitable to develop a simple server.
Here, I have a dialog box with one button and a text box. Button is for to start a server and text box is nothing but to display a message that server is started.
Please help me to find out the solution.
Thanking You in advance.

there are few samples in MSDN (VC CD), you can learn from those samples, they are not complex.

Hi includeh10
I don't have msdn. So if you can provide the such samples, it will be a great help to me.
Waiting for your reply.......

do you have an error at compile time or run time ?
what does it say to you ?

Dear Freinds,
Thank you all for the information and kind response. MY problem is solved. Actually the problem was at the client side. I was not initializing the socket at the client side at InitInstance.
But now it is solved.
Thank you once again for everything.
Bye

when you first run a MDI app you have the empty space, the dark gray background. I'm wondering if it's possible to draw in that space. For example is it possible to paint it white and place text, perhaps a bitmap, or just paint it white period.
thanks!

Yep, sure can. The MainFrame (or CMDIFrameWnd) will have a m_wndClientArea variable. From that you can either subclass that window and do what you want, or create a sub-control to place onto it. I used the sub-control method to create a "start page" that had a MRU list and stuff that really wasn't a document.

I guess I'm a little ignorant on implementing that solution. Do you have a sort of "sub-control for dummies" article on what you did? That is pretty much what I am looking for.
Thanks!

How do i go about adding a skin to windows? For example, make the window background and it's button controls have picture in them.
|
|
|
|
|
Search in codeproject there are about 10 skin examples with mfc and without...
Well... I am a beginner ...

You know how when you press the tab key on a window it goes through controls like buttons, radial buttons, and normal buttons in a certain sequence? Well, I have 3 edit boxes that I want to go in a certain sequence as I tab through them. How do I go about doing that?
Thank you in advance,

Under Resource Editor, press "Ctrl + D" to change the tab order.

i'm starting to make a remote access control program, what should i need to learn to develope such program? any suggestions would be appreciated!

Kinda sounds like a RAT (Remote Administrations Tool) to me, if its anything like that then the first thing you need to learn is how to use sockets

You can use this. You can get the hdc by GetDC...

"Avalon is the new Windows Desktop Composition Engine that replaces the old GDI and GDI+."
Is that totally impossible to replace GDI with an Avalon-like desktop compositing engine for older windows versions (name it: 2k/xp)?
What do you think? Won't Microsoft provide something like this before the release of longhorn?
