Excel Trial Dialog, Create An Excel VBA UserForm With Information Icon And Timer Enabled OK Button

Okay, so let’s get started. We’ll set up the user form and then add it to the VBA code. First open Excel and press ALT+F11 to enter the VBA editor. Go to the File menu and choose Insert–>UserForm. Name the new UserForm MsgBoxCountdown and set its Height property to 132 and its Width property to 242. Add a label to the UserForm and name it lbTrialMsg (set its Caption property to “This message only appears in the trial version of XXXX” without the quotes. ) – This will be our trial or nag message to the user. We will prefix this caption by passing it to the bespoke message. Add another label to the UserForm and name it lbCountDown (set its Caption property to “This test dialog can be closed” without the quotes) – this will be our countdown message to the user. Now add an image control and load in an image that looks like a question mark – you can easily create or adopt an image for this purpose. Finally add a command button and name it btnOK, set its caption to OK – this will be the button that the user is allowed to press until the timer interval expires.

Tip: why not add a frame control that’s half the height and full width of the userform to hold the lbCountDown label and the btnOK button and then set the userform’s back color to &H80000005& – this breaks up the userform and makes it look really cool. Quality

You should now have a nice looking UserForm and be in a position to add in VBA code. Double-click your OK button to enter the VBA code editor for the User Forms module. Modify the generated subroutine in the following code – you can paste it if you like:

‘=============================

‘ btnOK_Click, closes the UserForm

‘=============================

Private Sub btnOK_Click()

Unload me

end sub

Now add the following code to the top of the module – these are the Windows APIs we’ll use to restyle the dialog window and the interval variable we set to 5 (seconds) before enabling the OK button:

The choice is clear

Private Declaration Function FindWindow Lib “user32″ Alias ​​”FindWindowA” ( ByVal lpClassName As String , ByVal lpWindowName As String ) As Long

Private Declaration Function GetWindowLong Lib “user32″ Alias ​​”GetWindowLongA” (ByVal hwnd As Long, ByVal nIndex As Long) As Long

Private Declaration Function SetWindowLong Lib “user32″ Alias ​​”SetWindowLongA” (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long)

Const WS_SYSMENU = &H80000

const GWL_STYLE = (-16)

‘================================================== =======

Interval, set this time before the OK button is enabled

‘================================================== =======

private Const interval = 5

OK, next we’ll add the UserForm QueryClose event handler. If you don’t want to remove it then we’ll get to the UserForm Activate Event Handler in a minute just trying to turn it off at Red Cross can be used to trap. So add the following code:

‘================================================== ====================

‘ UserForm_QueryClose, workaround if you don’t want to hide the red close cross

‘================================================== ====================

private sub UserForm_QueryClose(cancel As Integer, closeMode As Integer);

Error in GoTo QueryCloseErrorHandler

Application.EnableCancelKey = xlErrorHandler

If CloseMode = 0 then

cancel = true

MsgBox “Oops, this dialog’s X is disabled, please use the OK button on the form”, vbCritical, “Kiosk 4.1”

end if

Exit sub

QueryCloseErrorHandler:

Another restart

end sub

Almost there, now we need to add the UserForm active event handler to the code. This is a work-horse of VBA code and I’ll go over it in a minute. Anyway, add in the following code (you can make yourself happy even if you add it in the comments):

‘================================================== ===================

‘ UserForm_Activate , a strange little error handling routine, it goes…

‘ – userform style to remove the red cross

‘ – Add restart point for hack attacks

‘ – Set up an error handler and tell Excel to use it

‘ – Disable the OK button

‘ – Start the countdown

‘ – Restart (CTR+Break) on the hack – this will start the whole process

‘ – If Time Up enables the OK button, OK will unload the UserForm

‘ – Interim DoEvents will still allow you to move the dialog

‘================================================== ===================

Private Sub UserForm_Activate()

Try another restart on error

Dim hwnd, as long as lStyle

hwnd = FindWindow(“ThunderDFrame”, Me.Caption);

lStyle = GetWindowLong(hwnd, GWL_STYLE);

Set window long hwnd, GWL_STYLE, lStyle and not WS_SYSMENU

Me.lbTrialMsg.Caption = Me.Tag & Me.lbTrialMsg.Caption

Restart:

error. empty

Error GoTo in TrialErrorHandler

Application.EnableCancelKey = xlErrorHandler

Me.btnOK.Enabled = False

Dim t as single

t = timer

do it

events

If the error. Number = 18 Then Resume GoTo

if round(t + interval – timer, 0) > 0 then

If the error. Number = 18 Then Resume GoTo

Me.lbCountDown.Caption = “This test dialog” and can be closed in round(t + interval – timer, 0).

others

If the error. Number = 18 Then Resume GoTo

Me.lbCountDown.Caption = “”

end if

loop while t + interval > timer

Me.btnOK.Enabled = true

Exit sub

TrialErrorHandler:

Another restart

end sub

The first part of the code tells Excel if an error occurs to skip it. Generally not a good practice but we don’t want the Excel debug box to ever be made available to the user. Then we style the dialog window to remove the red cross close button using Windows API calls. NB: For Office 2000 and later we use the ThunderDFrame class name (for Office 97, it’s ThunderXFrame). The lbTrialMsg caption is then set to contain the UserForm tag message we set before we show the UserForm and the message we set earlier. In other words we can call this UserForm from anywhere in our application with one of our pre-set key relevant messages. Then we add a goto point called Restart: we go there when the user presses the CTRL+Break keystroke combination. It also sets up Excel to use another goto point for our error handling and then tells Excel that we only want to use that point for all errors as they may occur. Next we disable the OK button. We set the variable ‘t’ to the current timer time and start looping until our interval expires – the interval variable was set to 5 (seconds) earlier. In the interim we use DoEvents to move the dialog around and allow the lbCountDown caption to be updated with our countdown message. When the interval expires we clear the lbCountDown caption. At the same time we still trap the CTRL+Break keystroke combination and then enable the OK button as the flow exits the Do loop. We then exit the subroutine. Used in conjunction with some VBA module security you have a handy little countdown message/nag dialog. If you don’t want to restyle the dialog window, simple API’s are removed and allow the UserForm QueryClose event handler to trap the red close cross.

OK, finally, double-click on this workbook module and enter the following:

The choice is clear

‘================================================== =========

‘ DemonstrateMsgBoxCountdown, run this to see the countdown dialog

‘================================================== =========

public sub displayMsgBoxCountdown()

MsgBoxCountdown.Tag = “(You clicked a feature):”

MsgBoxCountdown.Show

end sub

OK, now Debug–>Compile VBAProject Compile your code and check for any errors. Click anywhere on the code you entered above and press F5 to run the sub/user form. You should see your UserForm appear. Try pressing Ctrl+Break and watch the timer interval increase to 5 seconds. That’s what happened. Feel free to download the MsgBox Countdown Example Workbook from the link below.
