Picture Loaded in Condition Statement?

[[Gandalf]]

I didn't know how else to state this problem.

How you check if there is a certain picture loaded in an if statement. For example, what I tried, which obviously didn't work is:

code:

var pic := Pic.FileNew ("pic.bmp") if pic := Pic.FileNew ("pic.bmp") then     put "this picture is loaded" else     put "there is no picture loaded" end if

Do I have to make some boolean condition true when the pic is loaded, and then check for that? It seems like too much hastle...

Check the Error.Last and Error.LastMsg things. They return values after Pic.New is called, so you can use them to determine whether or not the pic has loaded.

Hmm, can you explain this a bit more? How do you use Error.Last and Error.LastMsg? If I add what I posted previously, the program doesn't even compile...

[Bacchus]

just check to see if the var = 0, if it does then the pic wasnt created

unsuccessful pic open error is error # 201

code:

var pic := Pic.FileNew ("pic.bmp") if Error.Last not= 0 then     put "this picture is loaded" else     put "there is no picture loaded" end if

Heh, you've got it backwards, zylum. Error.Last returns zero if there is no error.

Turing:

var pic := Pic.FileNew ("pic.bmp") if Error.Last = 0 then     put "this picture is loaded" else     put Error.LastMsg end if

[MysticVegeta]

Gandalf do you mean if the pic is already open? or the importing file error?

yup, you're right

Thanks for all that, I was looking for something else, but this helps too.

I found a simple way of doing what I wanted, I was just doing things the wrong, redundant way... Thanks for all the help.
