This error does not come always. So i am not able to reproduce the error also. No exact sequence also to reproduce the error. Stack :System.OutOfMemoryException: Out of memory. at System.Drawing.Graphics.FromHdcInternal(IntPtr hdc) at System.Windows.Forms.ToolStrip.OnPaint(PaintEventArgs e) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs) at System.Windows.Forms.Control.WmPaint(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ToolStrip.WndProc(Message& m) at System.Windows.Forms.StatusStrip.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) Error description: MyApplication_UnhandledException After this error i get a message saying, Insufficient memory to create bitmap. Close one or more applications to increase available. When i checked the memory usage of the application it was not that high. This error does not appear repeatedly. So how i can troubleshoot this error. How can it be solved? I checked running my application by using .Net memory profiler and redgate memory profiler. Below is a screenshot of the amounts of unmanaged memory usage. I don't know properly whether these values are high. UPDATE: i got the error again.checked the gdi objects and it was 9998.So the error was due to high gdi objects.Now question is how to solve.Then i used GDIView and checked.By that tool i got pen-2954 brush-59
27, 201018 0 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 http://stackoverflow.com/questions/17726092/outofmemoryexception-for-a-vb-net-application 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.

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 1, which, in 2’s complement notation, is a negative number, and some applications may not be designed to w
