Control.backgroundimage Return The File Name Of The Image?
May 26, 2011
I am using VS2010 VB.net and I am having issues with what would normally apear to be straight forward in VB6... I am looking at a control that will alternate its backgroundimage between two images, I wish to check which image is currently loaded to the control and change it to the alternative image.
If A1RectangleShape.BackgroundImage = my.resource.Image1 then
A1RectangleShape.BackgroundImage = my.resource.Image2
else[code]....
This only yields the type of image thats assigned to the control "System.Drawing.Bitmap" how to return the backgroundimage file name thats been assigned to the control at runtime, IE Image1 or Image2.

I am using images imported into My.Resources as images for items in my game. Now for the saving procedure I use pnl.BackgroundImage.ToString but that returns System.Drawing.Image. What I'd like to know is how to retrieve the name of the resources object that is the image of the panel.

I have a list of images in the resource file of a VB project and a particular picture box on my form gets populated with an image depending on certain conditions: picNotify.Image = My.Resources.[ImageName]
Later on in my program I want to query the name of the image in the picturebox. Technically I could create a variable and pass the name of the image in the same piece of code above but I dont like creating unnecessary variables if I am able to extract the information via code.

I'm looking to return a thumbnail image from a full size image stored as varbinary(max) in the database. I'll be using the thumbnails in a gallery-style view, so small size / efficient loading is crucial. I've been using an .ashx to return the full size image into a bound asp.net Image control, with the following code:
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim conn As New SqlConnection()
[Code]....
I realize it's probably best to address the re-size at the upload, and stored the smaller image as a discrete column. But in the meantime, is it possible to program the handler to re-size the image on the fly? Ideally, I'd be able to pass an additional query string parameter, something like isResized from the image binding, allowing the same handler to be used for both full size and re-sized images.

I have coded very simple asp pages to return an image when requested. But I need to do this from a vb.net application. So I assume I need to create a mini http web server. I have code for some that does not support asp or anything like that. Is there another method to return an image? Anyone have an example of this? Or again, do I need to find a web server control or app to use?

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 am writing a simulator for a complex technical system. I have created a custom control which inherits from the Button control. My project requires around 100 of these buttons, which function identically except for one difference. The background image cycles between 4 different images, (depending upon whether the button is pressed and/or the state of a Fault parameter), and this group of 4 images is different for many of the buttons. So when I drag a new control onto the form, I'd like to be able to specify which group of 4 images to use for this button.
Currently I'm using this syntax:
if not IsFault and isOn then
MyBase.BackgroundImage = My.Resources.FaultOnButton01
...
But this means I have to change each image in the code for each individual button. To simplify matters I though of using the Tag attribute. That way the class code can select the images by a process like this:
if not IsFault and isOn then
Mybase.BackgroundImage=My.Resources. + mybase.Tag + "01"
Obviously this syntax won't work, so my question is: How can I pass a built-up string value to the MyBase.BackgroundImage?

The code;
Private Sub PictureBox3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox3.Click
If user.Right > PictureBox3.Left Then
PictureBox3.BackgroundImage = (My.Resources.dooropen)
End If
End sub
Will not work as it should, when my player (rectangleshape) right is more than the picturebox.left it will not update the picture of the picturebox.

I'll explain this briefly as I need to be sure pretty quickly... basically, I'm developing a game. after the user gets 5 points, an alert box comes up saying "proceed to next level"... on the next (second level) I want the background image to change....
Now the default background is not a picturebox, it's actually part of System.Drawing.Bitmap I am using the same form throughout the entire game, so when it says "Proceed to next level" the game stays on the same form... Here's my Select Case statement to tell it to change the background image:

I have a form which contains an Image control. What I am trying to do is find a way to adjust an image according to the size of the control and have the image look normal no matter how I adjust the Image control. I want the actual image to fill the Image control completely and not loose any integrity.

i am hoping that the possibility to locate all the controls that contain a certain image from the resources, and swap out that image for every control that contained it, will help me narrow down on the simple coding.
something similar to:
for every control that contains backgroundimage=my.resources.imagefound
replace backgroundimage=my.resources.imagereplaced
i tried the above code and it did not work.. lol..

how I could search a given bitmap, say "test.bmp" or a printscreen, for two pixels that are next to each other and that have specified color values? The colors are: &H486596 and &H213D66. I then want to return the pixel positions in the image at which they are first located adjacent to one another. I'm only after the first instance of the occurrence. I wish to use GetDIBits as I hear that it's quicker. So I want to find the first instance where the color value for pixel (x,y) = &H486596 and (x+1, y) = &H213D66.
