[Quote=引用 5 楼 edisonli 的回复:]
1. GetWindowThreadProcessId
2. OpenProcess
3. GetModuleFileNameEx

请问这三个具体怎样实现吗,除了GetWindowThreadProcessId,其他两个我不知道怎样付参数

看MSND 上面写的很清楚

补充：GetModuleFileNameEx的适应环境
Client Requires Windows XP, Windows 2000 Professional, or Windows NT Workstation 4.0.
Server Requires Windows Server 2003, Windows 2000 Server, or Windows NT Server 4.0.

The OpenProcess function opens an existing process object.
HANDLE OpenProcess(
DWORD dwDesiredAccess,
BOOL bInheritHandle,
DWORD dwProcessId
);
Parameters
dwDesiredAccess [in] Access to the process object. This access right is checked against any security descriptor for the process. This parameter can be one or more of the process access rights.
bInheritHandle [in] If this parameter is TRUE, the handle is inheritable. If the parameter is FALSE, the handle cannot be inherited.
dwProcessId [in] Identifier of the process to open.
Return Values
If the function succeeds, the return value is an open handle to the specified process.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.

The GetModuleFileNameEx function retrieves the fully-qualified path for the file containing the specified module.
DWORD GetModuleFileNameEx(
HANDLE hProcess,
HMODULE hModule,
LPTSTR lpFilename,
DWORD nSize
);
Parameters
hProcess [in] Handle to the process that contains the module.
The handle must have the PROCESS_QUERY_INFORMATION and PROCESS_VM_READ access rights. For more information, see Process Security and Access Rights.
hModule [in] Handle to the module. If this parameter is NULL, GetModuleFileNameEx returns the path of the executable file of the process specified in hProcess.
lpFilename [out] Pointer to the null-terminated buffer that receives the fully-qualified path to the module. If the size of the file name is larger than the value of the nSize parameter, the file name is truncated and null terminated.
nSize [in] Size of the lpFilename buffer, in characters.
Return Values
If the function succeeds, the return value specifies the length of the string copied to the buffer.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
