VS2008 MFC编程，对话框显示多个图片和图标，运行2个小时，图片和图标不见了，请指教。谢谢。

我在VS2008中，用MFC编程，一个对话框显示多个BMP图片和ICON图标，程序运行2个小时左右，图片和图标都不见了，其他串口通讯和浮点显示没问题。
请指点，代码如下：
void CSlgoNewStationDlg::OnTimer(UINT_PTR nIDEvent)
{
// TODO: 在此添加消息处理程序代码和/或调用默认值
static int SyringeNum=0;
switch(nIDEvent)
{

case 1:
{

SyringeNum++;
if(SyringeNum>20)
SyringeNum=0;

// m_animIcon1.ShowNextImage();
static int i=0;
// if(SystemStatus==run)
i++;
if(i>=4)
i=0;

if(AlarmState[0]==run)
m_ctrlStateFlag1.SetIcon (AfxGetApp()->LoadIcon(IDI_ICON1+i));
else
m_ctrlStateFlag1.SetIcon (AfxGetApp()->LoadIcon(IDI_ICON1));

图片显示没有在OnPaint中。

[iamshuke]

应该是GDI句柄被泄露完了导致的。在CommDataDecode中，只有LoadImage，没有删除，可以DeleteObject m_ctrlTypePicture1.SetBitmap返回的句柄。

你现在的程序，用任务管理器看一下，加入“GDI对象”列，应该能看到GDI对象在不断增加。

[罗平]

正如楼上所说，检查资源泄漏。

[hdg3707]

hBitmap = (HBITMAP)LoadImage(
AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDB_BITMAP2),
IMAGE_BITMAP,
0,
0,
LR_LOADMAP3DCOLORS);
}

类似这样的都定义成全局变量,在程序初始化函数执行一次就行了.多次调用可能会有问题.凡是需要一次调用的,不是动态改变的都定义成全局变量,只在程序初始化执行一次就行了.

[3xcom]

hBitmap = (HBITMAP)LoadImage(
AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDB_BITMAP2),
IMAGE_BITMAP,
0,
0,
LR_LOADMAP3DCOLORS);
}
/////////////////////////////////////////
这个函数要不停调用，通过串口的数据来判断是现实图片1还是图片2.


m_ctrlTypePicture1是全局变量，请问如何删除句柄呢？

谢谢各位。

这个函数要不停调用，通过串口的数据来判断是显示图片1还是图片2./////显示打错了。

[hdg3707]

类似:
m_ctrlStateFlag8.SetIcon (AfxGetApp()->LoadIcon(IDI_ICON1));这样的语句,把:AfxGetApp()->LoadIcon(IDI_ICON1)在程序初始化函数里赋给一个全局变量,比如:av=AfxGetApp()->LoadIcon(IDI_ICON1);这样,在OnTimer函数里就这样:
m_ctrlStateFlag8.SetIcon(av);
图形操作要小心点,常常会把资源浪费完,而且不是当时或短时间,需要过一段时间才能看出来,我第一次编MFC的图形时,就是这样,后来全定义成全局变量,只在程序初始化函进行初始化一次,以后直接调用就可以了.当时每编一个程序,一定得长时间试看看不是资源浪费完了,就是不断的刷新屏幕,1到2个小时没问题后才放心了

[罗平]

可以在构造函数中加载图片，在析构函数中删除句柄

DeleteObject(m_ctrlTypePicture1);

图片1和图片2是固定的,因此你就可以在程序初始化函数里调用一次就行了,把它存在全局变量里,以后直接调用这个变量.

[hdg3707]

你删除m_ctrlTypePicture1这个,就不能显示图片了,相当于把这个控件删除了,所以还是按我说的,定义成全局变量来使用.我第一次用VC编程时就碰到这种情况,所以现在我知道如何处理这种情况

谢谢，我试试。有20个BMP图片和20个ICON图片，根据串口数据不同，显示不同的BMP和ICON图片。
