Convert double to Char/

Hello, I'm trying to convert a double to a char. how to acomplish that?

Code:

---

double t=sqrt(10)
MessageBox(NULL,t,"",0);

---

Always gives me an error, cannot convert double to char. Please give advice on how to solve this. Also, when I'm trying to use strcpy and strcat

Code:

---

double t=sqrt(10)
char T[MAX_LENGTH];
strcpy(T,"Hello this number is: ");
strcat(T,t);

---

Won't work. How to solve this as well? Thanks.

Code:

---

#include <stdio.h>

//...
double t=sqrt(10)
char T[MAX_LENGTH];

sprintf(T,"%d", t)

//...

---

try that.

:)

Code:

---

#include <windows.h>
#include "resource.h"
#define MAX 256
#define TIMER_10SEC 1
HWND dlg;
BOOL CALLBACK WndProc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam){
double x=LOWORD(lParam),y=HIWORD(lParam);
SetTimer(hwnd,TIMER_10SEC,1000,NULL);
        switch(msg){
        case WM_INITDIALOG:
                MessageBox(hwnd,"'Look, I can be the meanest son of a ***** in this school!'","Mr. Olds says",MB_ICONEXCLAMATION|0);
                break;
        case WM_CLOSE:
                DestroyWindow(hwnd);
                PostQuitMessage(0);
                break;
                        case WM_KEYDOWN:
                switch(wParam){
                case VK_ESCAPE:
                        SendMessage(hwnd,WM_CLOSE,0,0);
                        break;
                case VK_F1:
                        MessageBox(NULL,"hey","",0);

                        break;
                }       
                case WM_TIMER:
                        switch(wParam){
                        case TIMER_10SEC:
                                MessageBox(NULL,"Ms. Van Norton Suk!","...",MB_ICONEXCLAMATION|0);
                                break;
                        }
                        break;
        default:
                return 0;
        }
return TRUE;
}
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nShowCmd){
        MSG msg;
        dlg=CreateDialog(hInstance,MAKEINTRESOURCE(main_prog),NULL,WndProc);
        if(dlg==NULL){
                MessageBox(NULL,"Cannot create Windows, please recheck your system","From TZ",MB_ICONEXCLAMATION|0);
                return 0;
        }
                ShowWindow(dlg,nShowCmd);
               






                        while(GetMessage(&msg,NULL,NULL,NULL)){
                        TranslateMessage(&msg);
                        DispatchMessage(&msg);
                }
                return msg.wParam;

}

I want the Timer to be occured on the MAIN WINDOW, not the MessageBox. How?

Hello, every experts, I would like to know how to do this:

Code:

---

double Y=sqrt(10);
char X[MAX_LENGTH];
sprint(X,"%d",Y);
MessageBox(NULL,X,"",0);

---

When the messagebox pop up, it's something not sqrt of 10, and when I change 10 to 100, it gave me 0. What happened?

Use %f rather than %d.
