Hello my friends,
I wish to have a possibility to check multiple items from a combobox.
By example: I have in the combo items 7 colours, but I want to mark in some way 3 of them and the value of the combo to be retourned as an array.
I checked the samples, I searched the forum. Don't found something like this.
Can somebody give me a tip?
I can solve with a textbox, a commandbutton and a visible/invisible list, but I feel that exist something more simple here.
I am using HMG 3.1.1
Best regards,
Zoli B.

Mulitselect is available only in ListBox and Grid controls. I don't think it is possible in a combobox as of now.

Thank you for information Rathinagiri.
So I have to write a function with the 3 controls combination: textbox to display the current value, a commandbutton for make the list visible/invisible, and a list with the items and with multiselect.
something like:
xchoices:={'Red','White','Blue','Black','Yellow'}
xresult:={}
xresult:=combocheck(25,40,xchoices)
Happy HMG-ing...
Best regards,
Zoli B.

Hi,
As a beginner I solved the problem in folowing way:
The combocheck function will create the possibility to check from the list multiple items, but at overall look like a combo with multiple selection.
Not all the time we have place to keep the listbox visible.
Is not very proffesionist, but it works, and for me is very usefoul. I shared it, maybe is usefoul also for others.
First parameter is windowname.
Second is a name allocated by user. The checked items will be stored
as a string in the textbox created by the function. By example, in this case the textbox
name is "ccnametext". The main.ccnametext.value is really the result of the function.
Third parameter is the row where the texbox is placed
Fourth parameter is the column where the texbox is placed
Fifth is the leght of the textbox. The overall lenght of the combocheck will be this value+24
Sixth parameter is the name of the array containing the elements of the list
The example attached.
Best regards,
Zoli B.

Updated. No problems with controls overlapping.
Code attached.
When the items are selected, you have to press a simple Enter, or to click inside the textbox above.
Best regards,
