函数SHGetFileInfo()内存泄漏 [英] Function SHGetFileInfo() Memory leak

问题描述

当我想关闭一个进程时，我编写如下代码:

When I want to close a process, I write code as follow:

ASSERT(lpszExeName != NULL);
CString strExeName = lpszExeName;
int iPos = strExeName.ReverseFind(''\\'');
if (iPos != -1)
{
    strExeName = strExeName.Right(strExeName.GetLength() - iPos - 1);
}
HANDLE hSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if (hSnapShot == INVALID_HANDLE_VALUE)
{
    return FALSE;
}
SHFILEINFO shSmall;
ZeroMemory(&shSmall, sizeof(shSmall));

PROCESSENTRY32 processInfo;
ZeroMemory(&processInfo, sizeof(processInfo));
processInfo.dwSize = sizeof(processInfo);
BOOL bStatus = Process32First(hSnapShot, &processInfo);
while (bStatus)
{
    SHGetFileInfo(processInfo.szExeFile, -1, &shSmall, sizeof(shSmall), SHGFI_ICON | SHGFI_SMALLICON);

    strExeName.MakeUpper();
    CString strProcessName = processInfo.szExeFile;
    strProcessName.MakeUpper();
    if (strProcessName == strExeName)
    {
        HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, processInfo.th32ProcessID);
        if (::TerminateProcess(hProcess, 1))
        {
            Sleep(500);
        }
    }
    //::DestroyIcon(shSmall.hIcon);
    bStatus = Process32Next(hSnapShot, &processInfo);
}
CloseHandle(hSnapShot);
return TRUE;

但是内存泄漏，请帮帮我！谢谢！

But memory leaks, Please help me! Thank you!

推荐答案

我在OnTimer()中使用了此函数，当我运行程序一段时间后，

它不能正确运行，它提示没有更多资源.是的，记忆

它使用的非常庞大.我观察到，它增加了4kb

I used this function in OnTimer(), When I run my program, after a while,

it can not run correctly, it tips no more resource. Yeah, the memory

which it used has been very huge. I have observed, it increased 4kb

gradually.
