How can I recieve the Ints in editboxes int the dialog procedure? i tried using GetDlgItemInt and I didnt get any errors. I then decided to try a watch of the variable its being stored in and it came up and un defined, not un Initiated but undefined. Which i interperted as its not recieving the data from thye edit boxes correctly. Any suggestion?
TIA,

You need to add a global member variable for the edit box as type integer
Code:
UpdateData(); //Transfer data from controls to variables
// do something
UpdateData(FALSE); //Transfer data from variables to controls

What do you mean a "gloabal member variable"?
This sunds like C++ in which case Im only know C. If it is C++ is there anyway I can accomplish something similar in C?
Are the int's declared in the callback?
If you are not using static int variables you will be loosing the value collected by GetDlgItemInt() the next loop of the callback.
As each msg, including the paint msg generated by you using the watch will pass thru the callback.
//edit
If you are not getting errors on compile, how can you have an undefined variable?
//
I have them initiated as static int s so its not that Im losing data. Asfor the Edit question I have no Idea. That is just what the watch said.
//Edit\\
I dont know if it matters but I just noticed that it is replaced with "???" after the program exits.
If our not using UpdateData() you need to declare a pointer for GetDlgItem() and then access the data that way

What is this UpdateData() function? I looked in MSDN and my compilers(Borland) help files and couldnt find it.
It's a MFC function, which acts as GetDlgItem(), but for all controls that have a control variable attached to them. You won't use it with plain C, and there are arguments that you shouldn't use it for MFC code aswell.
Check your variables, pointers maybe?
Try gettting the input in another way, it might show you the error.
Declare an int as global, init it to -1 (or some value it could not pick up).
Watch the WM_CREATE/WM_INIT msg and look at the contents of the variable.
Enter your int into the edit and catch with GetDlgItemText() into a string as well the global int.
Also are you using EN_CHANGE?
ie
case IDC_TEST:
if (EN_CHANGE == HIWORD(wParam))
{
I tried pointers and I still get the same problem. I cant use the -1 thing since this is a graphing program across all quadrants so I have to take negative numbers(Althogh I havent implamented this yet).
