Bitmap error

[Smee]

i have the following code snippet

   If File.Exists(File.DirInternal & "/Jpegs/" ,Filename) Then
      Dim bmpImage As Bitmap
                bmpImage.Initialize(File.DirInternal & "/Jpegs/" ,Filename)
                .......
                .......
                .......
       end if

every so often a bitmap fails to load. There are only half a dozen or so and it is the same ones. They all used to load ok.

The error i get is the following

main_initscrollview2 (B4A line: 678)

bmpImage.Initialize(File.DirInternal & "/Jpegs/" ,Filename)
java.lang.RuntimeException: Error loading bitmap.

I could replace the jpeg but it may happen again so i need to know why it is happening. i am overcoming it with try catch but it is not a solution.

Where does this file come from?

 

[Smee]

It is a file i uploaded to the internet. it is only a small jpeg

 

[Erel]

Can you post the code that downloads the file?

 

[Smee]

it is just an ftp download

FTP.DownLoadFile(File.DirInternal & "/Jpegs/","/Jpegs/",NextFileName,False)

 

[Erel]

Are you checking that Success flag is true? Are you sure that this is a valid image file?

 

[Smee]

Yes and Yes. i am going to erase all the jpegs and re-download. As i said they used to display ok.

 

[Smee]

ok i downloaded the files again and everything is fine. I do not know what has caused the error or how to effectively deal with it
