Problem with deleting files

[rahavtom]

Hello!

 

I use VB.NET and I have a form which contain a picturebox control that I fill with a choosen image by:

 

Me.picImage1.Image = FromFile("1.jpg")

 

Then I have a different button which suppose to clear the picturebox control, and delete the file itself from the original windows directory.

 

The problem is that the picturebox is being cleared, but the file can't be deleted. It seems that it's locked or something, and I'm able to delete it only after I close the running program.

 

Does anyone know what can be done in order to delete the file during runtime?

 

Thanks!

Tom.

post some code where you implemented file deletation

This is the code I use to delete the file:

 

system.IO.File.Delete("1.jpg")

This is the code I use to delete the file:

 

system.IO.File.Delete("1.jpg")

 

You need to put the path inside of the quotes.

 

Example -

System.IO.File.Delete("C:\Program Files\1.jpg")

You need to put the path inside of the quotes.

 

Example -

System.IO.File.Delete("C:\Program Files\1.jpg")

 

Sure, in my source I put the full path as needed. I have a long path that I create in runtime, such "c:\" & ApplicationPath & PictureNumber & ".jpg"

I didn't write it here because it was too complicated, and I prefered writing more simple picture name as example.

 

Is there any other reason for that?

Can you give me the error message that is being displayed when you try to delete the file?

One More Thing, Assuming Your Paths Are Correct, It Seems To Be That You Can't Delete The File Because It Is Still In Use By Another Process. You Should Release The File From Memory, One Simple Way To Achieve This Would

Be To Type "GC.Collect" Right Before You Delete The Image. That Should Work.

Well, the original error message I got was:

The file can't be deleted because it is still in use by another process...

 

I added the line: Me.picImage1.Image.Diapose before I delete the file, so my code looks like this:

 

Me. picImage1.Image.Dispose

Me. picImage1.Image = Nothing

File.Delete("...")

 

The 'Dispose' solved part of the problem, because I'm able to delete the file whenever I want, but only when I still at that form.

When I cloe the form and open it again, and then try to delete the file, I get the same error message (still in use...).

I tried the GC.Collect as well but it didn't work...

 

Thanks,

Tom.

Hello!

 

Me.picImage1.Image = FromFile("1.jpg")

I'm not sure, but go ahead and put this code in right before you put a picture into the image. That should always dispose of the last used image. Then try

deleting the file again and see what happens.

 

If Not picImage1.Image Is Nothing Then

picImage1.Image.Dispose()

End If
