Status: Unverified
SYMPTOM(s):
Cannot use a picture located on the Internet with a Progress widget
Unable to create temporary file name for downloading image from internet. Error code = 5
Unable to create temporary file name for downloading image from internet. Error code = 2
The file (http://) for LOAD-IMAGE on the IMAGE imageName is invalid on the current system. (206)
No write privilege to the working directory
FACT(s) (Environment):
Windows
Progress 9.x
OpenEdge 10.x
CAUSE:
A picture coming from the HTTP has to be written in the disk before it is used. Therefore Progress has to have write privilege in the working directory.
FIX:
Change the temporarily the working directory to a location where it is possible to write. For example, assumed that you can write in C: you may use this code:
DO:
DEFINE VARIABLE tempWD AS CHARACTER NO-UNDO.
DEFINE VARIABLE SetCurrentDirectoryAResult AS INT NO-UNDO.
FILE-INFO:FILE-NAME = ".".
tempWD = FILE-INFO:FULL-PATHNAME. /*saving the current working dir*/
/*changing the working dir to a location where it can be written*/
RUN SetCurrentDirectoryA (INPUT "c:", OUTPUT SetCurrentDirectoryAResult).
IF SetCurrentDirectoryAResult <> 1 THEN
MESSAGE "Problem to set the CurrentDirectory of the process".
SELF:LOAD-IMAGE("http://www.google.nl/intl
l_nl/images/logo.gif").
/*changing back the working dir*/
RUN SetCurrentDirectoryA (INPUT tempWD, OUTPUT SetCurrentDirectoryAResult).
END.
DEFINE VARIABLE SetCurrentDirectoryAResult AS INTEGER NO-UNDO.
PROCEDURE SetCurrentDirectoryA EXTERNAL "KERNEL32.DLL":
DEFINE INPUT PARAMETER chrCurDir AS CHARACTER.
DEFINE RETURN PARAMETER SetCurrentDirectoryAResult AS LONG.
END PROCEDURE.
