Visual C++ 6.0 / MFC -> problem in listening by winsock
Asked by CSecurity in Windows MFC Programming, Microsoft Visual C++.Net, Microsoft Visual C++
Tags: Visual C++ 6.0
I am developing a simple chat program in Visual C++ 6.0 / MFC. this application has two part: client and server that user can listen or connect to another copy of my program. for connect and send data, fortunately I have no problem but for listening and get incoming data I have problem. I dont know how can I realize that some text sent by another application.
The attached code always wait for incoming data and never can response to another job even moving the form! So I want a code (like event) that I can realize incoming data and attach to end of editbox. I tried to do this by thread, but I with error messages found out that i can not alter form's property by thread!
and I have 3 simple questions too:
1-in my MFC application's form, when I press Esc, application exits. How can I prevent this?
2-I have trouble with member variables of controls on the form (like editbox). I set port_number for editbox1 as int, and in code, always port_number is zero (when i typed in editbox: 4545)
3-how can i do something (like show messagebox) when my application starts (form load)?
sorry for my long question, but if I could do, i would set 1000 points to this question.
thank you very much from now...
