POC++ - Totally suspend windows application
text
Body
copied!<p>I am developing a simple WinAPI application and started from writing my own assertion system.</p> <p>I have a macro defined like <code>ASSERT(X)</code> which would make pretty the same thing as <code>assert(X)</code> does, but with more information, more options and etc.</p> <p>At some moment (when that assertion system was already running and working) I realized there is a problem. </p> <p>Suppose I wrote a code that does some action using a timer and (just a simple example) this action is done while handling <code>WM_TIMER</code> message. And now, the situation changes the way that this code starts throwing an assert. This assert message would be shown every <code>TIMER_RESOLUTION</code> milliseconds and would simply flood the screen.</p> <p>Options for solving this situation could be:</p> <p>1) Totally pause application running (probably also, suspend all threads) when the assertion messagebox is shown and continue running after it is closed</p> <p>2) Make a static counter for the shown asserts and don't show asserts when one of them is already showing (but this doesn't pause application)</p> <p>3) Group similiar asserts and show only one for each assert type (but this also doesn't pause application)</p> <p>4) Modify the application code (for example, <code>Get / Translate / Dispatch</code> message loop) so that it suspends itself when there are any asserts. This is good, but not universal and looks like a hack.</p> <p>To my mind, option number 1 is the best. But I don't know any way how this can be achieved. What I'm seeking for is a way to pause the runtime (something similiar to <code>Pause</code> button in the debugger). Does somebody know how to achieve this?</p> <p>Also, if somebody knows an efficient way to handle this problem - I would appreciate your help. Thank you.</p>
