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?

View 3 RepliesI 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.
Here's the catch - for the program I'm making I would like to avoid creating a copy of the file in its totally unencrypted state (I'm using a modified, quick-and-dirty XOR cipher for that. It's secure enough for my purposes and faster than the stronger encryption). Anyhow, what I would like to do is read a block of data, de/encrypt it (in memory) and then write the changed bytes to the same location they previously would have been within the file.
I've found the problem a little outside my programming abilities, so I was wondering if anybody had a pre-made solution, links to appropriate examples, or an all out explanation.
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?
View 4 RepliesI was wondering if it someone could help me solve this problem. I have a full screen application with a panel in the center which is used to display different user controls and screens when the user uses the app.However, I have a rather large gradient image set as my form's background and it causes the panel to flicker every time controls are added. I find that when the background image is removed the flicker goes away. How can I keep the background image but eliminate the flicker? My form is already double buffered.

View 8 Replies1) 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).

View 1 RepliesI have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?

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.
