OutOfMemoryException On Bitmap.Clone Method?
Mar 23, 2010
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 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.

The following code loads a large 1 bit depth bitmap (10800x7226) on a PictureBox docked and with auto scroll bars.
After loading the bitmap I can drag the scrollbars, and it's very responsive.
After clicking the PictureBox and executing the Bitmap.Clone, dragging the scrollbars becomes very sluggish.[code]...

url...But what I'm looking for is just see if any alpha (0-254) is used in at least one of the pixels. Would the Bitmap.Lockbits and BitmapData method be the most efficient (speedy?) or is there another way. I've tried toying around with ColorPalette and the Alpha flag, but never could figure it out (and even if it is a way to check to see if the alpha channel is used at all).

I can't figure this out. I have a bitmap that will be used throughout an application, so I can't declare it with a Dim statement in a procedure, or it isn't recognized as having been declared in other procedures. So I declared it at the top of the form class, two ways. This one works: Private MyBitmap As New Bitmap(622, 461) It makes a bitmap to the exact size of a picturebox I have. But I want to be able to change the size of the picturebox and not have to worry about going back into this declaration to set things up, every time I decide to change the box's dimensions. So I tried this next version, but it doesn't work:

Here is a short program to demonstrate my question. I just want to extraxct a rectangle bitmap from a big bitmap.Code as follows:
Private
Sub Button3_Click(ByVal sender
As System.Object,[code]....
Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:
"MissingMemeberException was unhandled.
No default member was found for type 'bitmap"
I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

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

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 !

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."

There is something that I do not understand the point of, and it has to do with ICloneable.
Take the simple example below:

No... For the life of me I cannot understand why anyone would want a Shallow copy of anything.... And... I do not understand why the Me.MemberwiseClone would not work with list and arrays....

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.
