Hi DoEvents ist keine sleep anweisung. Sie ist dafür da, dem System die Kontrolle zurück zu geben, so das andere Dinge ausgeführt werden können. Mach einfach mal for i = 1 to 100000 next und for i = 1 to 100000 doevents next Bei obigem ist deine Aplikation tot, bis er fertig ist. Bei dem unteren kannst du noch andere Sachen starten. (z.B.: ein Cancel-Button einbauen) Beschreibung von Doevents (nach MSDN) ------------- DoEvents Function Yields execution so that the operating system can process other events. Syntax DoEvents( ) Remarks The DoEvents function returns anInteger representing the number of open forms in stand-alone versions of Visual Basic, such as Visual Basic, Professional Edition. DoEvents returns zero in all other applications. DoEvents passes control to the operating system. Control is returned after the operating system has finished processing the events in its queue and all keys in the SendKeys queue have been sent. DoEvents is most useful for simple things like allowing a user to cancel a process after it has started, for example a search for a file. For long-running processes, yielding the processor is better accomplished by using a Timer or delegating the task to an ActiveX EXE component.. In the latter case, the task can continue completely independent of your application, and the operating system takes case of multitasking and time slicing. Caution Any time you temporarily yield the processor within an event procedure, make sure theprocedure is not executed again from a different part of your code before the first call returns; this could cause unpredictable results. In addition, do not use DoEvents if other applications could possibly interact with your procedure in unforeseen ways during the time you have yielded control. gruss WarLocK1912
