19-03-2019 20:13:15 System.OutOfMemoryException: Out of memory.
You need to find out which part of your application is consuming all the memory, or windows resources.

sharat naik 20-Mar-19 7:24am

how any logic please suggest me.

Richard MacCutchan 20-Mar-19 8:22am

Sorry, I do not understand what you mean. The problem is clearly stated by the error message. The only way to fix it is to investigate what is causing your application to use up all the memory.

The code looks to be doing silly stuff with (many) Forms in a loop.

johannesnestler 20-Mar-19 11:46am

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
