Windows에서 openfile 대화 상자를 표시하는 방법은 무엇입니까?

Question

나는 win32에서와 같은 프로세스이지만 msdn에 따라 Windows CE 6.0에 나타나는 openfile 대화 상자를 얻으려고하고 있지만 작동하지 않습니다. 나는 코드의 검토를 위해 인터 휴식 일부를 제출

opendialog->lStructSize = sizeof (LPOPENFILENAME); 

귀하의 경우 4 포인터의 크기로 구조체의 크기를 설정합니다 :

#include <windows.h> 
#include <commctrl.h> 
#include <winuser.h> 
#include <stdio.h> 
#include <Commdlg.h>

HWND g_hWindow ; 

/* Function to modify the host window size to match the size of the movie. */ 
void resize_window(int width, int height) 
{ 
    RECT r; 
    r.left = r.top = 0; 
    r.right = width ; 
    r.bottom = height ; 
    AdjustWindowRectEx(&r,WS_BORDER,false,WS_EX_CLIENTEDGE); 
    SetWindowPos(g_hWindow, NULL, 0,0,r.right, r.bottom,SWP_NOMOVE|SWP_NOOWNERZORDER|SWP_NOZORDER);

    r.bottom = height ; 
    AdjustWindowRectEx(&r,WS_BORDER,false,WS_EX_CLIENTEDGE); 

    // Create the window 
    g_hWindow = CreateWindowEx(

    ShowWindow(g_hWindow, SW_SHOW ); // make the window visible on the display

Answer 1

LPOPENFILENAME opendialog; 
mb_char_t szFile[260]; 

opendialog = (LPOPENFILENAME) mb_malloc(sizeof (LPOPENFILENAME)); 
opendialog->lStructSize = sizeof (LPOPENFILENAME); 

.

당신과 같이 직접 스택에 OPENFILENAME를 할당 할 수 있어야한다 :

OPENFILENAME opendialog = {0}; 
mb_char_t szFile[260] = {0}; 

opendialog.lStructSize = sizeof (opendialog); 
opendialog.hwndOwner = g_hWindow; 
opendialog.hInstance = GetModuleHandle(NULL); 
opendialog.lpstrFile = szFile; 
opendialog.nFilterIndex = 0; 
opendialog.nMaxFile = 256; 
opendialog.lpstrInitialDir = NULL; 
opendialog.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST; 

GetOpenFileName(&opendialog); 

Answer 2

여기에 문제가 있습니다. 당신은해야한다 : 당신은 여기 OPENFILENAME 구조에 포인터를 선언하고 메모리를 할당하는

opendialog->lStructSize = sizeof (OPENFILENAME);
