MFC建立dll载入窗口问题

[Eddie780]

你好，请问我使用远程注入了一个dll，在dll中显示窗口，窗口一闪而过了，该如何解决？
窗口的对象是全局变量。

// CMFC_dllApp 初始化

BOOL CMFC_dllApp::InitInstance()
{
	CWinApp::InitInstance();

	
	AfxMessageBox(_T("窗口准备弹出!!!"));
	AFX_MANAGE_STATE(AfxGetStaticModuleState());
	mainformhwnd = ph->m_hWnd;
	ph->Create(IDD_DIALOG1);
	ph->ShowWindow(SW_SHOW);
	AfxMessageBox(_T("窗口已经弹出!!!现在能看到窗口！点了确定之后，窗口没了！ph是全局变量"));

	return TRUE;
}

加一个消息循环？

那就和这个例子代码的基本原理一脉相承（没消息循环Timer也不灵）：

#pragma comment(lib,"user32")
#include <stdio.h>
#include <time.h>
#include <sys/timeb.h>
#include <windows.h>
char datestr[16];
char timestr[16];
char mss[4];
void log(char *s) {
    struct tm *now;
    struct timeb tb;

    ftime(&tb);
    now=localtime(&tb.time);
    sprintf(datestr,"%04d-%02d-%02d",now->tm_year+1900,now->tm_mon+1,now->tm_mday);
    sprintf(timestr,"%02d:%02d:%02d",now->tm_hour     ,now->tm_min  ,now->tm_sec );
    sprintf(mss,"%03d",tb.millitm);
    printf("%s %s.%s %s",datestr,timestr,mss,s);
}
VOID CALLBACK myTimerProc1(
  HWND hwnd, // handle of window for timer messages
  UINT uMsg, // WM_TIMER message
  UINT idEvent, // timer identifier
  DWORD dwTime // current system time
) {
 log("In myTimerProc1\n");
}
VOID CALLBACK myTimerProc2(
  HWND hwnd, // handle of window for timer messages
  UINT uMsg, // WM_TIMER message
  UINT idEvent, // timer identifier
  DWORD dwTime // current system time
) {
 log("In myTimerProc2\n");
}
int main() {
    int i;
    MSG msg;

    SetTimer(NULL,0,1000,myTimerProc1);
    SetTimer(NULL,0,2000,myTimerProc2);
    for (i=0;i<20;i++) {
        Sleep(500);
        log("In main\n");
        if (GetMessage(&msg,NULL,0,0)) {
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }

    }
    return 0;
}
