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;}
