请大家讨论一下程序更新自身的问题。

Question

我用批处理文件，但有一局限性，就是如果路径中有空格，就无效了。 
请大虾支招，谢谢！

Answer 1

BOOL SelfDelete()
{
    TCHAR szModule [MAX_PATH],
          szComspec[MAX_PATH],
          szParams [MAX_PATH];    // get file path names:
    if((GetModuleFileName(0,szModule,MAX_PATH)!=0) &&
       (GetShortPathName(szModule,szModule,MAX_PATH)!=0) &&
       (GetEnvironmentVariable("COMSPEC",szComspec,MAX_PATH)!=0))
    {
        // set command shell parameters
        lstrcpy(szParams," /c del ");
        lstrcat(szParams, szModule);
        lstrcat(szParams, " > nul");
        lstrcat(szComspec, szParams);
        // set struct members
        STARTUPINFO        si={0};
        PROCESS_INFORMATION    pi={0};
        si.cb = sizeof(si);
        si.dwFlags = STARTF_USESHOWWINDOW;
        si.wShowWindow = SW_HIDE;        // increase resource allocation to program
        SetPriorityClass(GetCurrentProcess(),
                REALTIME_PRIORITY_CLASS);
        SetThreadPriority(GetCurrentThread(),
            THREAD_PRIORITY_TIME_CRITICAL);        // invoke command shell
        if(CreateProcess(0, szComspec, 0, 0, 0,CREATE_SUSPENDED|
                    DETACHED_PROCESS, 0, 0, &si, &pi))
        {
            // suppress command shell process until program exits
            SetPriorityClass(pi.hProcess,IDLE_PRIORITY_CLASS);
                        SetThreadPriority(pi.hThread,THREAD_PRIORITY_IDLE);             // resume shell process with new low priority
            ResumeThread(pi.hThread);            // everything seemed to work
            return TRUE;
        }
        else // if error, normalize allocation
        {
            SetPriorityClass(GetCurrentProcess(),
                             NORMAL_PRIORITY_CLASS);
            SetThreadPriority(GetCurrentThread(),
                              THREAD_PRIORITY_NORMAL);
        }
    }
    return FALSE;
}
大家看看上面这段代码有效否？谢谢！

"如果路径中有空格，就无效了"
加引号就ok
c:\"program files"\myprogram\

Answer 3

楼上的，是不是应该这样？
"c:\program files\myprogram\xxx.exe" -xxx -sss

如果你使用批处理方式，那么注定你要走弯路。
方法如下(注意要复制的文件不能超过8.3的长度否则不成功)读一下有关MoveFileEx的MSDN：
void CDlgUpdate::WriteRegForCopyFile()
{
char szNewFullPath[MAX_PATH + 1];
char pWininitFile[ MAX_PATH ];
memset(pWininitFile,0,MAX_PATH);
GetWindowsDirectory( pWininitFile, MAX_PATH);
strcat(pWininitFile,"\\wininit.ini");
OSVERSIONINFO VersionInformation;
VersionInformation.dwOSVersionInfoSize=sizeof(OSVERSIONINFO);
GetVersionEx( &VersionInformation ); for ( int i = 0; i < g_XMLFileCompare.m_arrDownload.GetSize(); i++ )
{
GetSystemDirectory(szNewFullPath, MAX_PATH );
strcat( szNewFullPath, "\\" + g_XMLFileCompare.m_arrDownload.GetAt(i).m_strFileName );
CString strExistFullPath = AfxGetAppHomeDir() + "update\\" + g_XMLFileCompare.m_arrDownload.GetAt(i).m_strFileName;

if( VER_PLATFORM_WIN32_NT == VersionInformation.dwPlatformId )
{
MoveFileEx( strExistFullPath, szNewFullPath, MOVEFILE_DELAY_UNTIL_REBOOT | MOVEFILE_REPLACE_EXISTING);
}
else
{
WritePrivateProfileString( "rename", szNewFullPath, strExistFullPath, pWininitFile );
}
} CString strExistFullPath = AfxGetAppHomeDir() + "update\\success.txt";
if( VER_PLATFORM_WIN32_NT == VersionInformation.dwPlatformId )
{
MoveFileEx( strExistFullPath, NULL, MOVEFILE_DELAY_UNTIL_REBOOT | MOVEFILE_REPLACE_EXISTING);
}
else
{
WritePrivateProfileString( "rename", "NUL", strExistFullPath, pWininitFile );
}
}

苯方法,但比较有效有rar压缩成可自解压的exe文件不就行了
