WS_HSCROLL in ES_READONLY edit box error
Well, I decided to make a base converter for practice... since im fairly new to win32. It works perfectly, I also wanted to put restrictions on my edit boxes, So I put ES_READONLY on them (I would rather of been able to bin edit box handle 1 or 0's, and hex 1-f but I dont know how , so tell me this to if you can =P), but I want a scroll bar on my binary edit box because it can long easily. I did so, but everytime I scroll over, it jumps back to the start... so I can't see whats past it the end of my edit box...
my code:
Code:
#include <windows.h>
#define ID_HWND_DEC 10010
#define ID_HWND_OCT 10011
#define ID_HWND_HEX 10012
#define ID_HWND_BIN 10013
#define ID_HWND_BUTTON 20000
const char g_ClassName[]="hwnd window class name";
