Saving Image To Database From Picturebox - 2008 / Framework 3.5?

Aug 20, 2010

I have a form containing a listbox showing a list of image names. It's bound to the database table. When an image name is clicked it shows the image and imagename in a picturebox and textbox respectively. When no image is selected in the listbox, a new record can be inserted by browsing a new image in the picturebox by an openfiledialog, writing the imagename in the textbox and pressing the OK button. When an image is already selected, the record can be updated by pressing the same OK button. The data is saved into MSSQL Server 2005. Corresponding table fields are Keycode int autono, logoname nvarchar(50), logo image.Now the problem, when I insert a new data with an image everything goes fine but whenever I try to update an existing data with an image it throws an exception- 'A generic error occurred in GDI+.' at the following line- 'pic.Image.Save(ms, pic.Image.RawFormat)'. Surprisingly when I update an existing data without any image in the picturebox no exception is generated. I have crossed checked it and seems that the problem is just at one point- 'Updating the image from the picturebox'. My code to insert/update the data by OK button and to populate it by listbox doubleclick follows:

Code:
Private ms As MemoryStream
Private arrImage() As Byte
Private conn As SqlConnection

Wpf - Get Image From Resource Dll As MemoryStream?

Oct 24, 2011

I use WPF and my program has images in a DLL resource file. I have this well working way to read in images from disk:

Private Function GetImageFromFile(ByVal fileName As String) As BitmapImage
Dim buffer As Byte() = IO.File.ReadAllBytes(fileName)
Dim memoryStream As New IO.MemoryStream(buffer)

[Code]....

Now, how can I get images in this MemoryStream-way from a DLL resource?

The basic problem: If I use simply the "bitmap.UriSource = whatever uri" way and load many images in sequence like an animation it builds up the memory. I tried with the above memorystream way and it worked perfectly fine, but then I store my images in a dll and I don't know how to do this trick. If anybody knows how to read many images from a managed dll without building up the memory

Display An Image (from MemoryStream) And Some Text And A Button?

May 21, 2009

This is interesting. We've spent the last day attempting to patch a problem with the following (legacy) code that continues to grow its process size. This is done in Visual Studio 2003.We have a form on which we display an image (from MemoryStream) and some text and a button. Nothing fancy. Looks something like this: Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)

[Code]...

Now. We've tried very numerous things. We've discovered that Disposing does nothing, and, indeed, the IDisposable interface doesn't actually touch memory. If we don't create a new CJ5Form_PTOperatorAcknowledgement form each time, the process size does NOT grow. But loading a new image into that form still causes the process size to continually grow.

Interface And Graphics :: Saving An Image To A Folder (A Generic Error Occurred In GDI+)?

Jun 24, 2011

I have a problem when trying to save a picture box image ( I am using vb2008 express edition)When i load my windows form I create a folder called images and the current date (eg images 24062011) using the following code.

Code:
Dim fold As String = "images" & " " & Format(Now(), "ddMMyyyy")
If My.Computer.FileSystem.DirectoryExists("C:usersmickdesktop" & fold) Then
MsgBox(" file exists")

[code].....

this works fine and creates the folder on my desktop. I then load an image into a picturebox and try to save it using the following code which is where the problem starts.

Code:
Dim filename As String = Format(Now(), "ddMMyyyy")
Dim imagename As String = "image"
Dim fileext As String = Drawing.Imaging.ImageFormat.Bmp.ToString

[code].....

so my problem is why does the 1st statement give me the error as surely as I have declared that fold = the folder name then that path should be correct, as the program is set to save the image automatically, not using the savefiledialogue I don't want to have to manually type in the folder name every time I use the program.

VS 2008 Generic Error Occurred In GDI+" - Saving Image From Picture Box?

Apr 3, 2009

I've written a simple application to encrypt an image (jpeg file) based on a password as a challenge to a mate of mine who reckons he's an ace hacker.I can encrypt the image no problem but when I try to save it using

[Code]...

I get "a generic error occurred in GDI+" raised. Googling reveals a few hits for this problem but seemingly mostly related to using databases rather than the file system.

Has anyone come across this? I don't want to paste all my code here in case my nemesis is watching, however basically I'm getting a reference to the PictureBox's Image property and manipulating the pixels using GetPixel and SetPixel, and then setting the picturebox's image property = my modified bitmap.

I understand that the error is generally related to the bitmap not being ready to be saved - is there anything specific I need to do to "close" the bitmap so it can be saved?The strange thing is that I'm sure this was working earlier today and now seems to have arbitrarily stopped working.
