Topic: If error then

Hello again wizards,
I successfully created a simple form where when I enter a number in a textbox it shows me the corresponding Image jpg.
(If I enter "1" it shows me "1.jpg", if I enter "2" it shows me "2.jpg" etc...
When there is no corresponding jpg I get a program error.
How can I bypass the error and leave the image empty if no jpg is available?
Attached the project + Folder with 5 images (1-5.jpg).
Thank You.

Re: If error then

Hi,
Is there a reason why you are using the 'image' object rather than the 'dbimage' object?

Well, I don't need to store the image in the database.

Re: If error then

If you don't want to store images in the actual database (and there are good reasons not to as the size of the database could quickly get very large), then you should set the dbimage1 'type' property to 'linkfile' and set the dbimage1 'copy to' property to be a discrete folder (local or networked) (see the screenshot in the attachment). 
When you do this, all that is stored is the link to the folder and file and so the database is kept small.

Thank You Derek,
I'm sorry I didn't explain myself so good.
I do not wish to choose the image from disk, I just wish to see it when I type the same number, just as it is working in the zip I sent.
Attached is a demo video of how it works & this is great for me.
The only thing I want to learn is how to bypass the error message when an image is not available for the typed number.
I guess its an "if else" but I don't know how to do it.
