Greetings,
another day another challange.
The problem I am facing currently is, that I don´t know how to pass a parameter to the popup window I have selected for a combobox.
i have tried a workaround, by opening that window in the "openening drop down list" process but i could not avoid expanding the list .... Is there a way not to expand the list or to close it imidiatly?
Thanks

Hi Sascha,
This is the good way to do it. In a nutshell:
- In the Description of the combo, the "Content" tab, select "Popup window" and the popup window to use.
- Use the Opening drop down list even to OpenPopup() the popup window with the desired parameters.
- Because you will use OpenPopup() the dropdown will not open.
Best regards,

Hi Alexandre,
this works fine. thanks!
but now i have another issue;
The binding source for my combobox is an array - it´s showing the description and its storing the unique ID. Selecting and storing the data works fine, but when I reopen the record, the display value is empty for both option ( Normal dropbox and popup window ) but it works if I am using a Table for the combo????
any idias?
Thanks
Sascha |

Hi Sascha,
Usually this kind of problems appears when you do not loat the "data source" of the combo before data is assigned to it.
Bad exemple:
COMBO = Valeur
COMBO..Content = sContent
// Results in empty value
Good exemple:
COMBO..Content = sContent
COMBO = Valeur
// Results in good value
This is very simplistic, but this is it. Make sure your SourceToScreen() (or the like) is called after your combo has it's possible values loaded properly.

HI Alexandre,
I am initalizing all my combox Arrays before I do the SourceToScreen...however it works fine when I do select "Table" as my ExpandType for the combobox.
Cheers,
Sascha |

Hi Sascha,
Check the gLink option and make sure all is correct. (Value stored, value displayed, what is assigned, etc.) There is a little detail somewhere.

Hi Alexandre,
finally I found the issue...
I am heavily using internal windows und ChangeSourceWindow() function.
I figured out that the setup of my combobox was working just fine on a normal window. Next I assign an internal window with a combobox directly on a window and it was also working fine.
The problem is the dynamic change of the internal window by using ChangeSourceWindow() function.
The trick now is to call SourceToScreen() right after calling ChangeSourceWindow()
Thanks again for your help.
Cheers,
Sascha |
