Need Some Information

[RJK]

Hey everyone, i'm new to Win32 API.

I just had a few questions:

1. If i need to get numbers from an EDIT box, i use GetWindowText, but i'm wondering, do you always need to convert the char to the specified data type (e.g. atoi(number)) ?

2. As i'm new i'm using char something[20] to put data into a buffer (i think), but ive seen another method:

something = (char*)GlobalAlloc(GPTR, 50) and GlobalFree((HANDLE)something);

I'm wondering, is there any difference, e.g. stable, efficiency, speed?

Thank,

Russell

For 1., it looks like you answered your own question.

For 2., GlobalAlloc and GlobalFree are used mainly for passing buffers between diverse processes. You can just use the C++ new[] and delete[] operators if you just need local memory buffers for your app.

If you want to get Integer from EDIT box, you can use GetDlgItemInt(). This way you don't have to convert char into integer.
