PictureBox And The OutOfMemoryException?
Nov 9, 2011
I've found similar threads about OutOfMemoryException, but I've got a new problem that seems really strange.The test Form is very simple, so everyone can test the problem I'm facing.I use VB 2010 Pro.
I have simple Windows Form with a picturebox, I've renamed "pbx".Now, I want to be able to add an image file as BackgroundImage with BackgroundImageLayout = ImageLayout.Tile.And also be able to move/rename/delete the image file. So the code must read and release the file.First of all, the test file I'm using now is a simple bitmap .bmp file, and really very light !

Dim output1 = System.IO.File.ReadAllLines(file).ToString
The file size is only 1 GB. My Page file is 128 GB. Why out of memory? It's 64bit system.

if creating a new object may cause OOM, then would creating a new Runtime.MemoryFailPoint cause an OOM (instead of InsufficientMemoryException ) as well?

An unhandled exception of type 'System.OutOfMemoryException' occurred in ystem.windows.forms.dllAdditional information: Error creating window handle.It appeared when I was loading a child form (frmPublisher) from the MDI form. I'm guessing this has something to do with the loaded form being overloaded or something? This didn't kind of error didn't happen when frmPublisher's only opened the database connection once (during the Load event). I modified the code to make sure that frmPublisher's subs only opened

I have a datagridview that has 65000 rows and 200 columns. I need to extract unique rows from the datagridview based on some sort of relevancy percentage.
While processing these rows it gives me an error "System.OutOfMemoryException" at around 47000 row. I searched for this exception over internet and found that it is related to RAM. I have 4GB RAM and my OS is Vista. However it would be used by people having as low as 512 MB RAM.

I have a windows form application made in Visual Studio 2010 SP1 Rel. I'm using SQL Server 2008 R2 for my database. I've been working on this project for a while now and I am almost completed with it. I recently had to add a field to one of my tables in my database, which hasn't given me much troubles in the past as I've had to do this before. To make sure I did it properly, I'll tell you how I added the field. I went to my database on my server and went to my table, tblOrderParts. I right clicked, and went to design. I added a field, Order_Delete, which I made a bit field so I could use a checkbox. When I went to my dataset designer, I used the wizard to add the field to the table in my program.
After I added it, I remembered that one of my forms was using a view I had created with that table that would need the checkbox as well, so I went back into SQL Sever to add that. Added in SQL with no problem, but when I went back to Visual Studio's dataset designer to add the field to my view, it won't allow me. I open the wizard, go to my view i created, vwAllOrders, and checked the box next to it. When I press Finish, though, I get, "An exception has occurred while attempting to set the data source generator property." I had to cancel out of the dataset wizard cause it wouldn't let me continue... even if nothing was changed.
Now it is also showing me an error in the Error section saying,
"Custom tool error: Failed to generate code. Exception of type 'System.OutOfMemory' was thrown."
Now that I've said the error, here's what I'm thinking is going on... Something must be wrong with the custom tool on my dataset. The tool name is MSDataSetGenerator. I went on more forums, and a couple mentioned trying to restart the custom tool by right clicking the dataset and going to "Run custom tool.' When I run it, it gives me another error. Not much different, but still different in wording.
The error it pops up say
"The custom tool 'MSDataGenerator' failed. Exception of type 'System.OutOfMemory' was thrown."

Are there other conditions that can cause this exception to be raised? I am attempting to use the method to take a section of the source bitmap in question (possibly equal to the entire source bitmap). I have checked my code extensively, including verifying the parameters of the Rectangle at runtime, and even tried hard-coding a Rectangle with parameters that I knew were within the bounds of the source bitmap, but have still received the error. I tried several choices for the PixelFormat as well.

I wrote a POS system a few years back, about 5 Then updated it about 2 years there after, so it has been running without problems for about three years now.All of a sudden of saturday, The following error comes up, System.outofmemory exception in mscorlib.All the system does is run the POS. Its not connected to the internet, nobody installs anything on there.And to make it worse, I now specialise in web strategy, and am a 'bit rusty' when it comes to vb.net applications.

I have written a lil program that takes input from the serial port, loads it to an array 6 by 100 and then saves it in an XML file. If i run the program more than 2 hours i get an exception of: "System.OutOfMemoryException occured in mscorlib.dll" One of the suggestions is , if you are creating an array make sure the size is correct. Here is my Array:

I have an image that I need to shrink. The original image is a grayscale PNG, which isn't a huge issues except that when I shrink it down, the thermal label printers pickup the artifacts and print them on the label. So, what I did was change the image to black & white (Format1bppIndexed) before resizing, like this:
Dim bte() As Byte = System.Convert.FromBase64String(imgStr)
Dim ms As New IO.MemoryStream(bte)
Dim bmp As New System.Drawing.Bitmap(ms)
[code]....
And then I resize it. This code works fine on my Windows 7 machine, but when I run it on the Windows 2003 Server box that it calls home, it always throws an OutOfMemoryException when it hits the bmp.Clone line.

I want to send files to my SQL server database. It works on smaller files, but when I try to send a 323MG file my byte array throws a OutOfMemoryException.Here is my code where the error happens...
Dim MediaFile As New FileInfo(txtFileName.Text)
Dim br As New IO.BinaryReader(New IO.FileStream(txtFileName.Text, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read, CInt(MediaFile.Length)))[code].....
The length of the file is 339476208.When I create a BinaryReader object and pass it in a Filestream object for the file that I am wanting to send to the database through FILESTREAM. I pass the length of the file to the byte array and I get a OutOfMemoryException.I have read in several places that the solution is to break it up into byte array chunks.

I'm downloading a bunch of files from a URI but when they get big, I get an utOfMemoryException. I thought at first it was MemoryStream error but I'm pretty sure now that the error is rooted in the declaration of an array of Bytes that's too large. (Half a gig is fine, 1.7 gig is not.)

I'm prompted with this error 'Exception of type 'System.OutOfMemoryException' was thrown' it was thrown when filling a dataset with 400,000+ records. And I think obviously is about memory matter because of the number of records to be transfer.My program goes this way.. after filling a dataset from a table it will transfer all data into another table. Now my question is, Is it possible in vb.net that while filling a dataset it transfers the record immediately into another table? Please give me an idea on how to do this.

from the vb web:
Quote:
The following Microsoft intermediate (MSIL) instructions throw OutOfMemoryException :
*
box
*
newarr
*
newobj
Does anyone knows what exactly does box means? and also is there anyway this statement will cause an outofmemory: Dim a As Boolean
What about if its just an empty object: Dim a As someobj

Dim line As String
[code].....
it works fine to read small file, example 2MB file, etc but it get error "Exception of type 'System.OutOfMemoryException' was thrown." when try to read 100MB file i think the error code because the file is too big
For Each Character As Byte In ASCIIEncoding.ASCII.GetBytes(line)
oReturn.Append(Convert.ToString(Character, 2).PadLeft(8, "0"))
oReturn.Append(Separator)
Next
how can i read 100MB or bigger file?or maybe is it another method / code to read a file and convert it into binary?

I have a PaintEventHandler connected to a picturebox via AddHandler.
In PaintEventHandler I have coded this for writing the drawing to PictureBox1.Image:
Dim PictureBox1 As PictureBox = CType(sender, PictureBox)
PictureBox1.Image = New Bitmap(PictureBox1.Width, PictureBox1.Height)
Dim bmp As Image = PictureBox1.Image
Dim g As Graphics = Graphics.FromImage(bmp)
... drawing something ...
PictureBox1.Image = bmp
Everything works fine but after running through the paint event handler and showing the picture on the screen it calls the painthandler again and again. It does not stop.
Replacing the code above with
Dim g As Graphics = e.Graphics
Makes it running. But then I cant save the Image to a file.

When trying to drag the image from the CurrentTilePicBox, the very moment I move the mouse while dragging the cursor becomes a circle with a cross and won't drag and drop into the new picturebox.
