Hi,
I want to write code for opening an external file or program from the C program.Could anyone tell me how to do this?
Say if I want to open calculator.exe I mention the path in the program and it should open it or say if I want to open "image.jpg" with the default program...How shall I do this?
Any sample code would be of great help.
Thanks in advance
Jump to Postcall win32 api function ShellExecute
Jump to Postline 25 is not necessary. You don't have to specifically load win32 api DLLs.
>>If I have to use shell execute not in MFC
I didn't ask you to use MFC -- MFC has nothing to do with ShellExecute function. Had you bothered to read the link I …
call win32 api function ShellExecute
//example of ShellExecute Function
#include <shellapi.h>
#pragma comment(lib,"shell32.lib")
static HWND hBut;
switch (message)
{
case WM_CREATE:
hBut = CreateWindow(TEXT(
"button"),TEXT("button"),WS_VISIBLE|WS_CHILD,100,100,100,100,hWnd,(HMENU)1,NULL,NULL);
case WM_COMMAND:
switch(LOWORD(wParam)){
case 1:
LoadLibrary(TEXT("shell32.dll"));
ShellExecute(hWnd,TEXT("open"), TEXT("http://www.rsdn.ru"), TEXT(""),NULL,SW_SHOWNORMAL);
}If I have to use shell execute not in MFC but like a simple function call without using the hWnd etc..how shall i?
