Photo capture

Author: Sytze de Boer

Posted: 2016-12-07 17:43:17   Link

I'm still totally lost trying to capture a photo via AVICAP32, so now

trying alternatives.

Using the Windows software Camera to take a photo.

All is good. It places the photo into a folder

C:\Users\Sytze\Pictures\Camera Roll

cdirs=FILETOSTR('picloc.txt')

ldirs=cdirs+"*.jpg"

lPics=ADIR(picfiles,ldirs)

trcask350 =cdirs+picfiles(1,1) &&Yes, it now knows the picture

trcask351 =Sys(5)+Curdir()+"PICS\"+Alltrim(Str(matties.code))+"_PHOTO.JPG"

**all is good at this stage

COPY FILE (trcask350) TO (trcask351)

Here's the problem

The file in the 2nd location is a zero byte file

Can anyone suggest why this is so?

The source file could be open. You can try getting an FLOCK before you attempt your copy. You also might want to look into using the Windows API to copy the file instead of the old xBase COPY FILE command.

Hi Richard

I think you're on to it.

Do you have any ideas how I can try and Close the file?

(I have tried to Kill the Camera but it seems to make no difference to the

file)

It sounds like the Camera application has the file open for exclusive access. I don't know enough to speak intelligently at this point other than to suggest you close the Camera application gracefully, as opposed to "killing" it.

Richard, I appreciate your honesty.

I don't have any idea how to Open the Camera (From within my application)

so I have even less idea how to close it graciously.

What is the format of the file?

1) Does the file have an EOL? That would be copied to cdirs.

2) Does the file end with a backslash? If not, you could get something like

C:\PICLOC1\PICLOC2*.jpg

assigned to ldirs instead of

C:\PICLOC1\PICLOC2\*.jpg

(Note the backslash, the THIRD backslash.)

3) Does the pics subdirectory exist?

It previously got written that way and subsequent runs have

done nothing to it? Try deleting it, and see what happens. I got

errors from your code, not a zero byte file until I corrected the three issues.
