VB.net users Unite!!

[Neorussell]

Hello I'm new and would like to introduce myself to everybody. The only reason I signed up is because of my lack of VB.net knowledge.

I got a couple of questions for people who wants to help.

Here's the set-up:
I changed the form background with an image
I want to be able to change the background image from another image by a click of a button. Is this possible? If so then what's the code for this. I'm quessing I have to change the assembly or something but what do I know.

I am using VB.net so

Double click on the button, in the click even put

form1.ActiveForm.BackgroundImage.FromFile(FileNameOfImage)

[dynamic_sysop]

are you after changing the image with another which is embedded? or an image from a location on the HD ?
if it's from an embedded resource....

[Color=Blue]Dim[/COLOR] path [Color=Blue]As[/COLOR] [Color=Blue]String[/COLOR] = Application.ProductName & ".DCP_0567.JPG"
        [Color=Blue]MyBase[/COLOR].BackgroundImage = Image.FromStream([Color=Blue]MyBase[/COLOR].GetType.Assembly.GetManifestResourceStream(path))

if it's from a file ...

[color=blue]MyBase[/color].BackgroundImage = Image.FromFile(" path of image here ")

Another way is:

Dim bit As Bitmap = New Bitmap("c:\yourPicture.jpg")
 
        Me.BackgroundImage = bit

Umm. Like I said I'm a real newb at this

On the three codes that were given to me. Umm where should I input them. DO I put them in the button or the somewhere else.

Don't use

Image.FromFile

It doesn't close the file, so if you call upon it again, you will have problems (File resource being used elsewhere or file already open).

Its not a bug per se, it was supposed to be 'by design'.

Anyway, just use FromStream instead. That way you can explicitly close the image file when you are done loading it, and reuse it.

yes, neo, code them to the button's click event (assuming you want the image to change when the user clicks the button).

great sig, btw, sysop.
