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

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.

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.
