Вам нужно выяснить, какая часть вашего приложения потребляет всю память или ресурсы windows.
sharat naik
как любая логика, пожалуйста, подсказывает мне.
Richard MacCutchan
Извините, я не понимаю, что вы имеете в виду. Проблема четко сформулирована в сообщении об ошибке. Единственный способ исправить это - исследовать, что заставляет ваше приложение использовать всю память.
Gerry Schmitz
Код выглядит так, что делает глупые вещи с (многими) формами в цикле.
johannesnestler
so you create unlimited new forms in a loop and used up all your memory... I don't even bother to think about what you are trying to do here, as Gerry Schmitz said "silly stuff". So you thought structuring your code is not needed... We all were there - just learn from it. Give your Code a structure that is easy to follow and you will avoid such pitfalls. E.g split the timer_tick in more reasonable chuncks, make shure your code runs in your interval (100ms really?), secure it against "overtaking", think About what you do with the forms and how you instantiate them (better reuse?) and so on. I'm pretty sure your Problem will just disappear - or just "fix" the memory consumtion and run in the next problem due to bad structure next week… just my 2c
