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));
if(AlarmState[1]==run)
m_ctrlStateFlag2.SetIcon (AfxGetApp()->LoadIcon(IDI_ICON1+i));
else
m_ctrlStateFlag2.SetIcon (AfxGetApp()->LoadIcon(IDI_ICON1));
if(AlarmState[2]==run)
m_ctrlStateFlag3.SetIcon (AfxGetApp()->LoadIcon(IDI_ICON1+i));

[解决办法]
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。
[解决办法]
正如楼上所说，检查资源泄漏。
[解决办法]
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.
