Combo-Box Problem

[Floppy]

Hello, I have a problem.

I'm creating a GUI with a combo. In the combo there are 60 items, but the combo shows only the first 30.

What's the problem?

The problem is no code

If that won't click within your head, probably nothing will:

#include <GuiConstantsEx.au3>

Opt("GuiOnEventMode", 1)

$hGUI = GUICreate("Test", 300, 100)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Quit")

Local $a_ConnectionList[3] = ["Intel Copper Ethernet", "BroadCom Fibre", "VMware Network Adapter"]
$ge_Label_Connection = GUICtrlCreateLabel("Please select the NIC to use:", 16, 10, 200, 17)
$ge_Combo_Connection = GUICtrlCreateCombo($a_ConnectionList, 16, 30, 249, 300, 0x0003)
For $i = 0 To UBound($a_ConnectionList) - 1
    GUICtrlSetData($ge_Combo_Connection, $a_ConnectionList[$i], $a_ConnectionList[0])
Next

GUISetState()

While 1
    Sleep(10)
Wend

Func _Quit()
    Exit
EndFunc

The key to your wish is 0x0003. Next time 1st RTFM (helpfile, you may reach it by pressing F1 in SciTe) and 2nd post your code or nobody will help you.

Regards,

Chris

EDIT: BTW, above I yesterday wrote complete bullshit probably having my head somewhere else. The option "0x0003" is meant to make the values displayed by the combo read-only. But at the same time the option seems to limit the combo to 30 items max. So also for me the question arises how to force showing all items?

FSoft,

If I populate a combobox with 60 items, I get the first 30 displayed and a vertical scroll bar to move down to the next 30:

Global $sString = ""
For $i = 1 To 60
    $sString &= $i & "|"
Next

$hGUI = GUICreate("Test", 300, 100)

$hCombo = GUICtrlCreateCombo("", 16, 30, 249, 300)
    GUICtrlSetData($hCombo, $sString)

GUISetState()

While 1
    If GUIGetMsg() = -3 Then Exit
WEnd

Are you saying that you do not get a scroll bar? Are you sure you have all 60 items in the GUICtrlSetData?

As everyone else has asked - please post your code because lacking that vital element it is very difficult to do anything at all to help you. :-)

I didn't post the code because it is a simple GUI with 1 combo.

I discovered that the problem is the $CBS_DROPDOWNLIST style.

If I use that style, i see only the first 30 lines; if i don't use it i see all items with the scrollbar.

Change your style entry to:

BitOR($CBS_DROPDOWNLIST,$WS_VSCROLL)

FSoft,

The problem is not "the $CBS_DROPDOWNLIST style". The problem is you overwriting the default styles.

If you read the Help file you see that the default style settings are: "$CBS_DROPDOWN, $CBS_AUTOHSCROLL, $WS_VSCROLL". So if you set only $CBS_DROPDOWNLIST , you lose the 2 SCROLL styles.

As Monamo has pointed out, you need to reset the $WS_VSCROLL style together with $CBS_DROPDOWNLIST to regain your scrollbar.

This is true for all AutoIt controls - if you set any styles you must also reset any default styles that you need and have overwritten. As Valik is fond of saying (among other things!): "AutoIt cannot read your mind - you need to tell it what to do!"

Thanks, it works...

P.S.: But who is Valik?
