I have a SQL Server database with a Table that has an image varbyte(max) field that I am using to store images. The issue is that when I am trying to insert an image in the field I need to .endEdit the dataSource before the assignment and again afer. If I don't do it before then nothing is stored.

View 1 RepliesI 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'm sure this has been addressed in other threads, but I wasn't able to come across any using the search function.I'm using the OpenFileDialog feature to have the user select a file. However, I want to have a label display the path of the file only.I've been using the OpenFileDialog1. SafeFileName feature to save only the name of the file, but I haven't found one that will save the path, but not the file name.I considered splicing the path and file name, but with an unpredictable path length and unpredictable file extension type, I thought it would get messy.

View 3 RepliesThe problem I am running into is the OpenFileDialog box. I am allowing the user to pick an image and I want to save the image location into a column in the database(this isn't the problem), I know how to get the image location and save it...The main problem is this. Each time I open up the "OpenFileDialog box" and choose an image, it remembers the last location used, but after the image is chosen, the program looks at the images location as the spot the database is...To sum this up: Each time I use the "OpenFileDialog" and choose an image, the program looks at the images location for the database instead of in the "Debug folder" (which is were I put the database) So i end up getting an error that it can't find the database. Everything usually worked fine until I used the "OpenFileDialog"...
