 Posted: Mon May 14, 2007 12:54 pm Post subject: From char to int? |
 |
|
I'm not sure I have to convert char to int but heres my problem:
I'm trying to compile this code
| Code: |
// other code up here...
char XCOORD[1024];
char YCOORD[1024];
GetDlgItemText (Hwnd,IDC_XC, XCOORD, 1024);
GetDlgItemText (Hwnd,IDC_YC, YCOORD, 1024);
TextOut(Screen, XCOORD, YCOORD, mytextbuffer, lstrlen(mytextbuffer)); |
unfortunately I get this error: | Quote: | | 'TextOutA' : cannot convert parameter 2 from 'char [1024]' to 'int' |
After looking for TextOut on MSDN, TextOut syntax is | Code: | BOOL TextOut(
HDC hdc, // handle to DC
int nXStart, // x-coordinate of starting position
int nYStart, // y-coordinate of starting position
LPCTSTR lpString, // character string
int cbString // number of characters
); |
The X and Y are in "int" therefor my char buffer doesn't work. 
Can you guys help me fix this problem?
EDIT: tried atoi(&XCOORD); and reinterpret_cast with no success

You have to use atoi() on each item in the array individually. Then add them all together while multiplying each number by a power of 10 to keep it in its correct spot. Optimize it yourself, I also haven't tested it so there is bound to be errors.
Edit: Cut the code, after I went over it I decided it was too ugly to let out into the world.

Are XCOORD & YCOORD ever going to contain a character? (I dont see why co-ordinates would)
If not, just make them integers.

I suppose if you really want them to be char's try:
| Code: |
TextOut(Screen, (int)XCOORD, (int)YCOORD, mytextbuffer, lstrlen(mytextbuffer)); |

That would just give the ascii value of the number, not the number itself.
For example:
1 in ascii is 49.
