I used the Data Validation tool to show a message when a cell is clicked. Is there any way to format the message that appears (i.e. font, color, etc)?

Thanks for your help!

Excel Facts

What do {} around a formula in the formula bar mean?
{Formula} means the formula was entered using Ctrl+Shift+Enter signifying an old-style array formula.

Don't think so. Only solution I could suggest would be a VBA Worksheet Change event to perform the validation and a custom UserForm could be designed how you wish to display any warning. Bit OTT maybe.

I believe a Data Validation message (as are comments) are really Windows ToolTips. These can be changed in your Windows Properties. In 2003, RightClick the Desktop and Choose Properties>Appearance>Advanced>Item =ToolTip
Format Font and Background Color. Note this will change ALL tooltips in any Windows Application!!

And will only work if you open the workbook on your PC.

Hi.

As it turns out, the little Data validation input message box has a Class name of EXCELA. I found out using WindowSpy . So i thought maybe I could use some API functions and the Selection_Change event in order to format its background color and text . and guess what it worked ! well at least in excel 2003 where i tested it.

Here is a WORKBOOK DEMO.

I have tried commenting the code for easier reading.


This code goes in the worksheet module :

Code: 
Option Explicit
 
Private WithEvents wb As Workbook
 
Private Sub wb_BeforeClose(Cancel As Boolean)
 
   [COLOR=seagreen][B]'safety measure in case[/B][/COLOR]
    [COLOR=seagreen][B]'the wb is not unhooked before closing.[/B][/COLOR]
    If lPrevWnd Then Call ClearHook
 
End Sub
 
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
 
    Dim sTitle As String, sInput As String
 
    On Error Resume Next
 
   [COLOR=seagreen][B]'***********************[/B][/COLOR]
    [B][COLOR=seagreen]'shouldn't be necessary[/COLOR][/B]
    [COLOR=seagreen][B]'but just in case.[/B][/COLOR]
    Set wb = ThisWorkbook
   [COLOR=seagreen][B]'**********************[/B][/COLOR]
 
    sTitle = Target.Validation.InputTitle
    sInput = Target.Validation.InputMessage
 
    If Len(sInput & sTitle) <> 0 Then
        Call StartTimer(ByVal sTitle, ByVal sInput)
    End If
 
    ClearHook
 
End Sub

This code goes in a Standard module :

Code: 
Option Explicit

    y As Long

    Top As Long

        KillTimer 0, lTimerID
        Call FormatDVMsg(ByVal sInputTitle, ByVal sInputMessage)
    End If
 
End Sub

Once the hook is installed, it should work for all cells with DV input massages.

Also, despite using a timer and a msg pump loop, this doesn't add a strain to the system as they are both terminated once the DV cell is desactivated.

I'm not even going to pretend I've got a clue what any of that is doing.

Thanks Domski.

What version of excel did you try the code on ? I am curious to know if it works on other than XL 2003.

Regards.

Jaafar-

I copied and pasted the code, but when I click on a cell with a VD input message the whole workbook closes. I am kind of a newbie when it comes to VBA, so I'm not sure if I am doing something wrong.

Thoughts?

Thanks!

Did you paste the code in the relevant modules as stated on my post ? ie: first one on the worksheet module and the second on a standard module .

Also, what excel/office version do you have ?

Why not download the Workbook Demo in the link and see if it works or if you still get the same problem .

Regards.

Hi Jaafar,

I really appreciate your code that you posted on this site!!!

However, is there any way to designate the location of the input message box of data validation to a specific location on the sheet upon opening your document??

I know you can move the input message box around of the data validation, but I am looking for a more secure position of it.

Do you think that this is possible to include this in your current code posted here?? or Is this a question for a new thread??


Thanks again,

Pinaceous
