This code contains it to save an image to a SQL c# outofmemoryexception 64 bit Server table. But sometimes a Out of memory exception happens when I'm returning the binary data from the table to display the image. This is my code to convert image before save. openImage.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp"; if (openImage.ShowDialog() == DialogResult.OK) { pictureBox1.Image = new Bitmap(openImage.FileName); pictureBox1.SizeMode = PictureBoxSizeMode.CenterImage; lblImgInfo.Text = openImage.FileName; FRM_ImageViewer imgver = new FRM_ImageViewer(openImage.FileName); imgver.Show(); string strFn = openImage.FileName; FileInfo fiImage = new FileInfo(strFn); long m_lImageFileLength =fiImage.Length; byte[] m_barrImg = new byte[Convert.ToInt32(m_lImageFileLength)]; FileStream fs = new FileStream(strFn, FileMode.Open, FileAccess.Read, FileShare.Read); int iBytesRead = fs.Read(m_barrImg, 0,Convert.ToInt32(m_lImageFileLength)); fs.Close(); } and this is my code to retrieve the image from the database // DTSelectedJobs is a DataTable in csharp. byte[] barrImg = (byte[])DTSelectedJobs.Rows[0].ItemArray[11]; string strfn = Convert.ToString(DateTime.Now.ToFileTime()); FileStream fs2 = new FileStream(strfn, FileMode.CreateNew, FileAccess.Write); fs2.Write(barrImg, 0, barrImg.Length); fs2.Flush(); fs2.Close(); FRM_ImageViewer imgvwr = new FRM_ImageViewer(strfn); imgvwr.Show(); Can someone please give me an advice how to find the error? c# .net winforms share|imp

(4 bytes) and thus is limited to 4 Billion. That’s the equivalent of saying a vehicle license plate number consists how to handle out of memory exception in c# 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 http://stackoverflow.com/questions/24671990/how-to-solve-the-out-of-memory-exception-in-c-sharp 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.

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 work with “negative” pointers. Now when I run the code I get 3.5 Gigs: More than twice as much memory!

Recently after a long run of my application, I am facing " Out of memory exception" from an active window and asserting. What might be the reason ? Here I am using PInvoke calls . Will it causes issues ? Is GC will not work properly on PIO calls ? Please suggest. Posted 22-Sep-11 19:40pm SKOTAJI1.4K Add a Solution 3 solutions Top Rated Most Recent Rate this: Please Sign up or sign in to vote. Solution 2 Accept Solution Reject Solution GC works properly, but this question has nothing to do with the problem. Do you think that with GC you don't have memory leaks? If so, this is completely wrong. Of course it eliminates memory leaks you would make due to forgetting to release some memory, but it cannot help if you have wrong design. It's pretty easy to design code which leaks managed memory. As to forgetting to release some resources, this is still a source of other kind of memory leaks, of unmanaged resources. In particular, you need guarantee that you properly call Dispose for all types implementing System.IDisposable, because many of such objects allocate unmanaged resource
