Message loop is added in the loop:

 MSG MSG. 
If (GetMessage (& amp; MSG, NULL, 0, 0)) {
TranslateMessage (& amp; MSG); 
DispatchMessage (& amp; MSG); 
}

In the later; I found a packet loss occurs, how to do? Such as the first variable should always have a value; But now update some changes;

CodePudding user response:

Authentic way is not in the void CTEST_MFCApplication1Dlg: : OnBnClickedButtonOpen () inside of circulation message loop is added; But
Will void CTEST_MFCApplication1Dlg: : OnBnClickedButtonOpen () inside the loop into
Using CTEST_MFCApplication1Dlg
A member variable for loop control variable,
Another state variable difference is in the loop,
The SetTimer starts a timer,
CTEST_MFCApplication1Dlg: : OnTimer according to processing cycle control variables and state variables in each cycle,
