WM 22 Android - strange behaviour loading images

Hi All,

I have a form with 3 buttons (BTN_1, BTN_2, BTN_3) and 5 image controls linked to a db.

the button code:

HReadSeekFirst(imagedb,imageID,gnValue)
FileToScreen(WIN_test,imagedb)

Each button has a different value and should show a different set of 5 images.

The problem is that the images do not show every time each separate button is tapped, or will only show if the other two buttons have been tapped previously. For example,

tap BTN_1 - images blank
tap BTN_2 - images shown
tap BTN_3 - blank
tap BTN_1 - shown (previously blank)
tap BTN_2 - blank (previously shown)
tap BTN_3 - shown

Any ideas how to fix this?

Thanks

Pete

Hi Pete,

the first thing to do would be to check the result of the hreadseekfirst function. With the code as displayed, nothing says that a record is found by your search.

Hi Fabrice,

There is a line in between that sets a global variable from the imagedb file, which is being updated correctly, so I know that the record is being found. I should have mentioned this.

HReadSeekFirst(imagedb,imageID,gnValue)
gs_db_input=imagedb.db_code
FileToScreen(WIN_test,imagedb)

It seems to be a display issue of some kind?

edit- they are svg format, in case that makes a difference. Everything works fine in Windows test mode.

Cheers

Pete

I'm having a similar problem with this 'selecting a row' code on a Combo:

HExecuteQuery(QRY_species_by_ID,hQueryDefault,+COMBO_QRY_animal_3)
HReadFirst(QRY_species_by_ID)
WIN_Count.IMG_animal_3=QRY_species_by_ID.species_bcs3

The image shows in Windows test mode, but not on Android.

Just to add, on a new record the images are displayed as intended; if the record is edited and a different selection is made the new image is not displayed.
