您可以使用 CreateTimerQueueTimer函数

  HANDLE timer_handle_; 
 CreateTimerQueueTimer（& timer_handle_，NULL，TimerProc，user_object_ptr，10，0，WT_EXECUTEDEFAULT）; 
 // callback 
 void TimerProc（PVOID lpParameter，BOOLEAN TimerOrWaitFired）
 {
 user_object * mgr =（user_object *）lpParameter; 
 mgr-> do（）; 
 DeleteTimerQueueTimer（NULL，timer_handle_，NULL）; 
 timer_handle_ = NULL; 
} 
 

I have a console application that is using a DLL file that uses a SetTimer() call to create a timer and fire a function within itself. The call is below:

SetTimer((HWND)NULL, 0, timer_num, (TIMERPROC)UnSyncMsgTimer)) == 0) 

It is expecting to receive timer messages, but this never happens. I assume because mine is a console application and not a standard Windows GUI application (like where the DLL file was originally used). This stops a key part of the DLL files functionality from working.

My application needs to stay a console application, and I cannot change the DLL.

Is there a work around to make this work?

You can use CreateTimerQueueTimer function

HANDLE timer_handle_;
CreateTimerQueueTimer(&timer_handle_, NULL, TimerProc, user_object_ptr, 10, 0, WT_EXECUTEDEFAULT);
//callback
void TimerProc(PVOID lpParameter, BOOLEAN TimerOrWaitFired)
{
    user_object* mgr = (user_object*) lpParameter;
    mgr->do();
    DeleteTimerQueueTimer(NULL, timer_handle_, NULL);
    timer_handle_ = NULL;
}
