I am doing a project wherein I have to display an image in system memory (in a buffer of size: column*row) onto a form or say a picture box. The size of an image will be known to me by pixel's column & row matrix. The picture (frame) will be captured using a CMOS camera. I am using VB.Net for developing the User Interface
I need to know how to use listview, I'm having trouble using it.What are listviews uses?What can be listed in listview?What cannot be listview?If an image is in listview, will it display a thumbnail of the image?
I am capturing Frames from a camera and storing the RAW DATA of the picture(frame) in a buffer(declared as Byte). Now my question is that: Is it possible to display the Image onto a picture box directly from the Raw Data stored in a Buffer, without converting it to a Bitmap or any other Image type? If so how to do this?
I have a database object and one of the items is an image which is stored on the net. i wish to display this image in a datarepeater. I have the data repeater setup correctly and the item in question is a picturebox. here is a basic idea of what i am trying to accomplish
For Each itm In joblist Dim j As New Job j.ID = CInt(itm.ID.Value)
[Code].....
Well i ran this and it doesn't display anything on the datarepeater. I believe this is because the image hadn't been placed on the control before i take it off, but i would have expected that it would be there for other items in the list but it isn't. I then got thinking i should put this onto an imagelist so i dropped an imagelist onto the form and realised i still would have the same issue as i'd be placing an empty image onto the image list and would have the problem of taking it off so abandoned the idea.
My program parses chat room text. In the room there are smileys that get displayed. What I'm trying to do is parse out the image URL, download the image and put the smiley in the correct spot between the text of the message.I can do the parsing and downloading of the image into the datagridview but this only works of the column is set as an image column. Obviously due to the nature of the program I need to be able to put both text and images into the same cell. How can I do this?
1) Add a new record - I can currently add records text to access database, but not images.
2) Get the ID [URL]I'm not sure how to integrate this code into my code. I am stuck here.
3) Save the image in the filesystem using the ID as a filename - I can save the upload an image and save the image to a directory on my computer, but I am unable to name the image that of the ID of the access database.
4) Update the database to put the filename in the record you just created. - I am unable to do this as well (obviously).

I have a picture box on my form. I can load images which I read from a database into the box.
The problem is that the images are all sorts of different shapes and sizes. Some are square. Some are portrait. Some are landscape.
How do I configure the imagebox so that the pictures are reduced to fit, and keep their proportions. As I've got it at the moment, the rectangular ones are distorted into a square, which makes some of them look pretty strange.
