I'd like to verify if an image control has an image loaded . If it does , I want to unload that image (and load no image) , but if the image control has no image loaded , I want to load an image . Is it possible ?
If ImageMY.Image.Equals(Nothing) Then
ImageMY.Image = System.Drawing.Image.FromFile("C:ImageBlaBlaBla.jpg")
Else

Currently my ListView sorts items by image.index. So 0 is at the top, then 1, 2 and so on. Think of it as an IRC chat room nick list. Ops at top then the rest are sorted alphabetically

I use this code to get an image and add it to a image list
Visual Basic
Private Sub LoadWebImageToPictureBoxd(ByVal ImageURL As String)
Dim objImage As MemoryStream
Dim objwebClient As WebClient
Dim sURL As String = Trim(ImageURL)
Dim bAns As Boolean
[Code] .....
The code at the bottom should set the image depending on what the items index is but it doesn't work.

I know this is old hat, but when you're faced with a problem you cannot solve yourself, you need to find someone with the correct answer.In short, go to the wise.
I am working on an application that has a lot of records, and it uses a listbox control bound to a binding source attached to a table in a data source.A new record with data is added to the binding source's attached table, and, of course, to the underlying sqlServer database table:

I created a new cursor (it works properly, I tried it in windows 7) but is not working for me in the program.I took the Windows cursor (aero_helpsel_xl, from C:WindowsCursors) and it appears to me the same error.i use with this code:
Me.Cursor = New Cursor("Patch..")
The problem say:: "{"Image format is not valid. Image file may be corrupted.
Parameter name: stream "}"
edit: I realized what the problem ... It can read only cur files with 24-bit color and lower - but it shows only two colors: black and white.

I've been searching for hours tonight searching existing posts, other websites and all i can find are examples of how to capture a image from a webcam.Does anyone have any code that simple talks to the camera device via WIA, and then saves every image found on the device to a hard drive?I found this code below. Credit i cant tell you as i have a bunch of different flavors of code, but this only saves the file as a tmp file, and not the actual image file i expected after selecting?

In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?

I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?

I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.
This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .
So I have made a folder named "Pics" inside my application and added two images into it.
How do I get to this local folder in the following code?
Picturebox1.image = system.drawing.image.fromfile (??? )
instead of the usual,
Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?

I hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

I've got an app where the user uploads an image and the app resizes the image three different ways based on different variables. They all use the same image. I can't check to see if it's done using the image so I wondered if there was a way to check to see if the file is writable. A small loop that exits once it becomes writable (or "deleteable"). Working out of VB.NET.

I have a report that i'd like to display an Image for each record. But not all records have an image. The problem I have is that the last image is then repeated in the next record.
I would like to know how to have any empty field display a default image.
Code I have in report
Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
Me.Image21.Properties("Picture") = Me.PhotoLink
End Sub
Photolink is a textfield and Image21 is an Image.
