参考了一些资料但是不晓得为什么，总是启动服务的时候失败，希望能有一个原因，为什么？错在哪里，谢谢！！！

在看！！

晕了，用GetLastError()查的是操作成功完成。

[zhouqingyuan]

看来爱莫能助了，StartServiceCtrlDispatcher(ste)返回0，可用GetLastError（）却
查不到错误。

你的程序有两个错误：
1。BOOL RegisterService(const char * servicename)
{
//...
char * filename = GetFilePathName();
wsprintf(buf,"\"%s\"",filename);
这里弄巧成拙的多加了一层""，结果服务管理器找不到你的你注册的程序

2。DWORD WINAPI monitor(LPVOID param)
{
//。。。
find = Process32First(SnapShot,&ProcessInfo);
while(!find)
{
if(strcmp(ProcessInfo.szExeFile ,name)==0)
{
find = TRUE;
break;
}
else
{
find = Process32Next(SnapShot,&ProcessInfo);
}
}
if(!find)
{//。。。
这里你列举进程和匹配居然用同一个flag，晕~~~

3。int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmdLine, int nCmdShow)
{
//。。。
SC_HANDLE scm = OpenSCManager(NULL,NULL,SC_MANAGER_CONNECT);
if(scm!=NULL)
{//。。。
已经作为服务启动了，你却又把自己启动一遍，莫名其妙。造成的结果就是崩溃。

oyd(cplusplus说的两个错误，确实，现在以更正，谢谢仁兄！！！
