delphi - How might I find out the source of long delays on resizing the main form? -

-

i have d2006 app contains page control , various grids, etc on tabs. when resize main form (which ripples through , resizes on form aligned something), experience long delays, several seconds. app freezes, idle handler not called , running threads appear suspend also.

i have tries pausing execution in ide while happening in attempt break execution while in troublesome code, ide not taking messages.

obviously i'm not expecting point me @ errant piece of code, i'm after debugging approaches might me. have extensive execution timing code throughout app, , long delays don't show in of data. example, execution time of main form onresize handler minimal.

if want find out what's taking time, try profiler. sampling profiler answer question pretty easily, if you're able find beginning , end of section of code that's causing trouble , insert outputdebugstring statements around narrow down profiling.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

(the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
