Combobox Autocomplete

[Abu Rashid]

Hi,

I've searched the forums for this question without luck.

Is it possible to have auto-complete in a Combobox, so that as you type something into a Combobox it auto-completes the word from the list.

Thanks.

good job searching:

try again.

look in the help

_GUICtrlComboAutoComplete

[Abu Rashid]

Well I guess I only searched for "combobox autocomplete" which doesn't bring up that thread.

also that is not exactly the kind of autocomplete I want, as it gives a dropdown rather than just autocompleting the actual text you're typing.

Thanks anyway though, it might have to do.

Look in the help of the latest release.

gafrost,

I didn't find anything in the help on this issue.

Also "_GUICtrlComboAutoComplete" I could not find anywhere, can you please elaborate on this?

Do you have the newest "Released Version" or even the last Beta?

Released Version

[Abu Rashid]

I didn't notice a new version released.

I had the latest beta version 3.1.1.133 I think.

Will check latest stable release, thanks for your time.

[Abu Rashid]

either I'm just not looking hard enough, or it's really well hidden, but I can't seem to find it anyway in the 3.2 help file.

[Abu Rashid]

ok, it's under the UDF section.

thanks.

[SmOke_N]

ok, it's under the UDF section.

thanks.

Just an FYI, when you see someone refer you or anyone to the Help file for a function, and you see an underscore "_" in front of the Function name, it's going to be in the User Defined Functions (UDF) section.

[Abu Rashid]

Thanks smoke, I gathered that now. I did realise before this was for UDF's, however I wasn't aware there were "official" UDF's actually documented in the helpfile, I assumed they were just contributions of users supported only by the users who created them.

[tAKTelapis]

hmm, ive just used this UDF in a program.

its a list of names, however, i have noticed that if you start to scroll down the list, it automatically moves the item under your cursor into the box.

then auto completes for the input, if you keep moving your cursor down the list, the list starts scrolling (i have 680 odd names in the list)

any ideas on preventing it automatically moving the information under the cursor into the input part of the combo box?

[Abu Rashid]

I've noticed the same glitch, I was thinking you probably need to catch the event of the combo list being opened and makesure it doesn't do auto-complete in this case.

Another question I have which I'm unable to fidn in the help file about combo's is how to set the text to nothing. GUICtrlSetData seems to only be able to set the entire list to nothing, rather than just the control's displayed text.

[tAKTelapis]

you mean, so that the combo box appears blank, until you bring down the list and choose what you want?

there are two spots where this is set:

a:

GUICtrlCreateCombo ( "text", left, top [, width [, height [, style [, exStyle]]]] )

the "TEXT" part should be left as "" and then it will not display that.

b:

GUICtrlSetData ( controlID, data [, default] )

the DEFAULT part of this should be left out.

that way, the combo box should appear blank. all of mine have so far. and those are the only two things i can see that might affect it.

Not a glitch, especially when no code is provided to show how you used it.

The control is created with a blank text field, but the problem is after an item is selected, there is a "Clear" button which should clear the combo, but not clear the list items. GUICtrlSetData replaces the list items.

[tAKTelapis]

the combo box in that example does not get affected.

my combo box has 680 options in it...

which requires the combo box to have a scroller on it,

here is my code:

i know its rough, but it does the job i need, i have a habit of making do with what i already know whenever i can.

now, couple it up with a text document... (called "users.txt", and in the same directory as the script) containing upto 100 records.. and you will see the issue that has arisen.

its designed as a way to get a password back for a users account, users dont have access to change there own password, so they are pre-set.

btw, my text doco is in the following format:

codefirstnam last name

ie:

123456tak telapis

it works for my purposes.. but its the way the drop down list behaves thats the issue.

gafrost,

Apologies for using the term glitch.

I used it exactly as it is, in the example code shown under the UDF section in the help file.

[GaryFrost]

my combo box has 680 options in it...

which requires the combo box to have a scroller on it,

I gave you a different example above, just adapt that to what you have.
