方法如下:

#define AW_HOR_POSITIVE 0x00000001
#define AW_HOR_NEGATIVE 0x00000002
#define AW_VER_POSITIVE 0x00000004
#define AW_VER_NEGATIVE 0x00000008
#define AW_CENTER 0x00000010
#define AW_HIDE 0x00010000
#define AW_ACTIVATE 0x00020000
#define AW_SLIDE 0x00040000
#define AW_BLEND 0x00080000
void CPageDlg::OnClose() //實現淡出功能
{
//定義AnimateWindow的函數指針
typedef UINT (CALLBACK* LPFUN)(HWND hwnd, DWORD dwTime,DWORD dwFlags);
LPFUN pp;
HINSTANCE hInst=::LoadLibrary("user32.dll");
if(hInst)
{
pp = (LPFUN)::GetProcAddress(hInst, "AnimateWindow" );
pp(GetSafeHwnd(), 300,AW_BLEND|AW_HIDE); // 紅色的是動畫類型
::FreeLibrary(hInst ); //綠色的是時間
} //下同
CDialog::OnClose();
}
同理:
void CHipDlg::OnShowWindow(BOOL bShow, UINT nStatus)
{
CDialog::OnShowWindow(bShow, nStatus); //顯示時不過不是淡入,而是滾動
//主要是表現下參數的不同
// TODO: Add your message handler code here
//定義AnimateWindow的函數指針
typedef UINT (CALLBACK* LPFUN)(HWND hwnd, DWORD dwTime,DWORD dwFlags);
LPFUN pp;
HINSTANCE hInst=::LoadLibrary("user32.dll");
if(hInst)
{
pp = (LPFUN)::GetProcAddress(hInst, "AnimateWindow" );
pp(GetSafeHwnd(), 500, AW_SLIDE|AW_VER_NEGATIVE);
::FreeLibrary(hInst );
}
}
關於參數問題:
函數原型:BOOL AnimateWindow(HWND hWnd,DWORD dwTime,DWORD dwFlags)。
函數功能:該函數能在顯示與隱藏窗口時產生兩種特殊類型的動畫效果:滾動動畫和滑動動畫。
參數含義:
hWnd:指定產生動畫的窗口的句柄。
dwTime:指明動畫持續的時間(以微秒計),完成一個動畫的標準時間爲200微秒。
dwFags:指定動畫類型。這個參數可以是一個或多個下列標誌的組合。標誌描述:
AW_SLIDE:使用滑動類型。缺省則爲滾動動畫類型。當使用AW_CENTER標誌時,這個標誌就被忽略。
AW_ACTIVATE:激活窗口。在使用了AW_HIDE標誌後不能使用這個標誌。
AW_BLEND:實現淡出效果。只有當hWnd爲頂層窗口的時候纔可以使用此標誌。
AW_HIDE:隱藏窗口,缺省則顯示窗口。
AW_CENTER:若使用了AW_HIDE標誌,則使窗口向內重疊,即收縮窗口;若未使用AW_HIDE標誌,則使窗口向外擴展,即展開窗口。
AW_HOR_POSITIVE:自左向右顯示窗口。該標誌可以在滾動動畫和滑動動畫中使用。當使用AW_CENTER標誌時,該標誌將被忽略。
AW_VER_POSITIVE:自頂向下顯示窗口。該標誌可以在滾動動畫和滑動動畫中使用。當使用AW_CENTER標誌時,該標誌將被忽略。
AW_VER_NEGATIVE:自下向上顯示窗口。該標誌可以在滾動動畫和滑動動畫中使用。當使用AW_CENTER標誌時,該標誌將被忽略。
返回值:如果函數成功,返回值爲非零;如果函數失敗,返回值爲零。在下列情況下函數將失敗:
窗口使用了窗口邊界;窗口已經可見仍要顯示窗口;窗口已經隱藏仍要隱藏窗口
