is there any way to check if a bmp or jpg file is valid in FiveWin / xHarbour, since I have my application in a folder of pictures of products show on the screen as the sale goes through.
more is happening to stop the application and find that you have some images that the program can not open and lock.

Just try to open the image inside a TRY/CATCH/END structure and trap the error.

There is no way to test via Windows API or whatever, because with try catch
entering the try block and catch the app was already, and that they want to avoid

Sorry, I don't understand.

I say this, I wanted to see if the photo or image file is valid.
example:

if checkimg ("teste.jpg")
obmp: loadbmp ("teste.jpg")
endif

something like this. Why try to catch suppose it to have it established in the block between the try and catch the app as it is happening.

has no function of the Windows API function to check or some of the FreeImage?

sorry my bad inglish i used google, rsrsrsrs

FUNCTION CHECKIMG( cImg )

    LOCAL lOk := .F.

    TRY
        // try to load cImg
        lOk = .T.
    CATCH
    END

    RETURN lOk
