The original question remains (subject):
I can add an image control manually to the form, but how to commit a
picture without the whole api stream stuff...
tested on 2.4.0 with HSQLDB embedded, and with MySQL (JDBC/UnixODBC),
the steps are just insert the image control, bind it to the binary
field, and that's all: right click, and choose the image.
If you already tried this, and checked other stuff (for example PK),
this may be an issue.
Hi
I know this is not quite the proper response for a DEV list email,
rather a USERS list...so forgive me.
This could be an issue as in bug - but it could be something different
also.
Image controls are little funny in that they don't receive focus from
the desktop manager and because of this you can get into trouble if you
layout the form without this in mind. For instance if you have an image
control as the only control belonging to, or displayed from a
datacontrol where the datacontrol is sub-form. But IIRCC that is not the
only way to get in trouble with it.
There is an old discussion about this in an old post ( circa OO.o 2.0 )
at oooforum that touches on this image control issue and it could use a
new round perhaps.
Saving you some time to dig through a very long and rambling post there,
here is the section of interest.
Now, when I split the Photo column out of the employees table and
created the emploueePhotos table with just 2 fields I was setting up a
lack of focus problem. To add the image control to our form I had to
to do this.
<snip>
The same is done for the employeeNotes table.
<snip>
Now at run time notice that as I move from one of the controls on the
main form to the notes control the form navigation bar updates itself
to reflect the different record counts, etc. between the two distinct
dataform objects. Each assigned to a different physical table. This
change on the navigation bar is triggered by a change of focus amongst
the controls. And here is the problem, the image control can't receive
focus, so the navigation bar never knows to switch over to its
dataform object. I can add images it it (the image control), remove
images from it all I want, but the form navigation bar will never
allow me to save the controls contents to to the underlying table.
If I had any control attached to the employeePhotos table, that could
receive focus, then moving into it would activate the navigation bar
and it would immediately recognize the change in state of the image
control allowing me to save the data. But I have no column that would
make sense, and even if I did it would be a very awkward process then
for the user. One other solution, using basic code, would be to assign
one of the Mouse Button events to a procedure and in the procedure
change the status of the dataform object for employeePhotos table.
Remember though, this example was to use now basic code.
