Out Of Memory Error In Vb.net
27, 201018 Share 0 0 When you run your VB or C# application, you might get an OutOfMemoryException thrown, even if your machine has lots of memory. Every 32 bit process has a 2^32 bit (4 Gig) address space. That means every pointer has a size of 32 bits (4 bytes) and thus is limited to 4 Billion. That’s the equivalent of saying a vehicle license plate number consists of 6 digits and thus there are 1 million possible numbers. That 4 Gigs is divided into half: the user application gets the lower half and the OS gets the upper. (This boundary can be changed: see below). Start VS 2010. File->New->Project->VB or C# Windows WPF Application. Paste the VB or C# code below. It creates a heap then allocates 100Meg of memory in a loop continuously until an exception is thrown. On my 64 bit Windows 7 machine with 8 Gigs of RAM (your digital camera or phone might have more memory!), I get about 1.4Gig allocated before it dies. Iter #10 1,048,576,000 Iter #11 1,153,433,600 Iter #12 1,258,291,200 Iter #13 1,363,148,800 Exception Exception of type ‘System.OutOfMemoryException' was thrown. Now choose Project->Properties->Compile->Build Events->PostBuildEvent Command and added these 2 lines call "$(DevEnvDir)..\..\vc\vcvarsall.bat" x86 "$(DevEnvDir)..\..\vc\bin\EditBin.exe" "$(TargetPath)" /LARGEADDRESSAWARE Note: the positions of the quotes are critical The first line calls a BAT file that makes various tools available on the path. The second runs EditBin on the target binary, using the LARGEADDRESSAWARE flag (that’s almost all left hand keys on the keyboard!) Also uncheck the option: Project->Properties->Debug->Enable the Visual Studio Hosting Process The only effect of these 2 lines is to call EditBin to toggle a bit in the EXE. When the EXE starts a process, that entire process is flagged as able to work with pointers above 2G. With such pointers, the high bit is a

Didnt realise i needed that for images. Dispose() frees up the space the image was occupying when it had been loaded into the picture control Learned something new Thanks for the help mate Kevin Was This Post Helpful? 0 Back to top MultiQuote Quote + Reply ← Previous Topic VB.NET Next Topic → Page 1 of 1 Related VB.NET TopicsbetaOut Of Memory Exception :( Out Of Memory Exception / Parallel.For Loop / Large Numbers Adding Images To ImageList Out Of Memory Argument Out Of Range Exception In A Weird Situation How To Fix Index Out Of Range Exception Out Of Recources (memory Problem) Out Of Memory

Jari Nevala 1.3k 35 22.2k Why does this simple application run out of memory after a few minutes? Jul 13 2010 8:59 AM Hi all, I have this really simple application that has a timer. Every time the timer "ticks" (the interval is set to 1 ms) a screenshot is taken (a new Bitmap object is created and a 100x100 pixel portion of the screen is copied into the Bitmap object). Also a label´s text is updated to display time since starting the timer. The weird thing is that I get a "Out of memory" exception after the timer has been running a couple of minutes. I tried changing the interval, but I get the same error whether the timer is 1, 10 or 100 ms. Can someone please explain why this happens? Clearly I have some kin
