Sorry, I meant 4.0 instead of 4.5! .NET 4.0 requires WindowsInstaller 4.5 which runs on Windows XP..Prerequisite is .NET 4.0

Look in the Application event log and check for any errors in there. A guide to posting questions on CodeProject Click this: Asking questions is a skill. Seriously, do it. Dave Kreskowiak

I managed to fix the issue. The problem was that that flash object remains active when you open another form and it must be stopped or disposed. This is the solution, if anybody will get this error in this situation.

OutOfMemory probably wouldn't cause this. But you know the drill, debug it. What exactly causes it (not circumstances, but specific action being executed in code)? Does it still happen if the work that the background worker does is executed on the main thread?

Go to ParentThank you for your reply. I have found the problem. The problem was caused by the web server, because it didn't accept ASP.NET version for my project. So I have to choose another provider. Sorry for repost, I thought I have chosen the wrong category.

Ok then, it seems that this is the solution. Thank you for your time and help.

Ok so I have a problem. I have to create the form of the page with multiple data which will be inserted from textboxes and labels. I need to arrange them and in the final, I found a way to create more pages if is necessary. But I can't set the height of the windows forms larger than 780 and I really don't know why :)) Is there any way to create a structure for the form specially for printing? I'm kinda beginner with this type of projects..

When you installed your database, did you by any chance install it into your program directory? You know, the directory that's normally protected so that software can't do malicious things to your system.

Did you DEBUG your code? Where did the exception occur? _userManager ?? HttpContext.GetOwinContext().GetUserManager(); What is _userManager AND HttpContext.GetOwinContext().GetUserManager() are NULL. What would then be the behaviour? In Word you can only store 2 bytes. That is why I use Writer.

I see. Thank you for your answer, it helps!

It's the same problem as your other code - integer division. 15 / 8 = 1.875, but since the variables are integers, only the integer part is used: 15 / 8 = 1 You then multiply that result by 100, which (unsurprisingly) gives a final result of 100. You then store that final result in a double, but it's too late - you've already lost the fractional part at step 1. You need to convert one of the values to a floating-point type before the division: medie_sim = ((double)totalsim / totalsimyes) * 100; // or: // medie_sim = (totalsim / (double)totalsimyes) * 100; "These people looked deep within my soul and assigned me a number based on the order in which I joined." - Homer
