Hi. I was wondering how to get the information from an edit box. I know how to get it as an array of chars, but not as a float (which is what I need). Thanks in advance!

If you can retrieve an array of characters, you can convert this into a float (using atof, or stringstreams).

One way is (assuming you're using C++):

#include<cstdlib>
#include<windows.h>
#include<windowsx.h>

...

float floatValue(HWND editbox){
unsigned int length = Edit_GetTextLength(editbox);
char* str = 0;
float value;
try{
str = new char[length + 1];
Edit_GetText(editbox, str, length)
value = atof(str);
}catch(std::bad_alloc&){
throw;
}catch(...){
delete str;
throw; //Re-throw exceptions etc while not leaking memory
}
delete str;
return value;
}
