Putting an Hyperlink in a MsgBox !!

Jaafar Tribak · Jun 27, 2021

Hi all,
I have been playing with this little project recently which, as the thread title states, allows for adding an hyperlink to the native vba MsgBox.
At the moment, I managed to make this work with only one hyperlink per MsgBox...

This little "tool"can come as a handy, a quicker and a more compact alternative to using a userform and then formatting & coding a Label control so it looks and behaves like a real hyperlink.

Example workbook:
HyperlinkMsgBox.xls

Easy to use logic :

VBA Code:

Function HyperlinkMsgBox( _
        ByVal PROMPT As String, _
        ByVal HyperlinkText As String, _
        ByVal HyperlinkTarget As String, _
        Optional ByVal BUTTONS As VbMsgBoxStyle, _
        Optional ByVal TITLE As String _
    ) As VbMsgBoxResult

The HyperlinkText argument takes the specific letter\word out of the prompt and will represent the clickable hyperlink display text.
The HyperlinkTarget argument takes a string that represents the hyperlink target (either a Folder address or a URL).

So, for instance:
IF
PROMPT = "Come visit MrExcel for all of your VBA programming needs.

"
HYPERLINK_TEXT = "MrExcel"
HYPERLINK_TARGET = "www.Mrexcel.com"
Then, the MrExcel word will be markedup and clicking on it will launch the www.Mrexcel.com website

2- Code usage examples:

VBA Code:

Option Explicit

Sub Test1()

    Const PROMPT = "Click this Hyperlink text to launch your C:\ Drive folder from explorer"
    Const TITLE = "Testing ..."
    Const HYPERLINK_TEXT = "Hyperlink"
    Const HYPERLINK_TARGET = "C:\"
    Const BUTTONS = vbInformation
    Dim lRet As VbMsgBoxResult

    lRet = HyperlinkMsgBox(PROMPT, HYPERLINK_TEXT, HYPERLINK_TARGET, BUTTONS, TITLE)

End Sub


Sub Test2()

    Const PROMPT = vbNewLine & "Come visit MrExcel for all of your VBA programming needs. :)"
    Const TITLE = "Hello EXCEL/VBA/ world ! "
    Const HYPERLINK_TEXT = "MrExcel"
    Const HYPERLINK_TARGET = "www.Mrexcel.com"
    Const BUTTONS = vbInformation
    Dim lRet As VbMsgBoxResult

    lRet = HyperlinkMsgBox(PROMPT, HYPERLINK_TEXT, HYPERLINK_TARGET, BUTTONS, TITLE)

End Sub

Late note;
I have written and tested this code in excel 2016 x64bit - I haven't tested it on other platforms but, I guess, it should work just as well.
In case of any issues, please let me know.

Just discovered a subtle error in the MsgBoxProc callback function which may potentially affect the MsgBox default background color... I have now fixed this error and have updated the uploaded workbook example. !

Below is the small code section that has been corrected :

VBA Code:

Private Declare PtrSafe Function GetSysColor Lib "user32" (ByVal nIndex As Long) As Long

VBA Code:

    Select Case Msg
        Case WM_CTLCOLORSTATIC, WM_CTLCOLORDLG
            Call SendMessage(hwnd, WM_NCACTIVATE, True, 0)
            MsgBoxProc = CreateSolidBrush(GetSysColor(COLOR_WINDOW))
            Exit Function
        Case WM_DESTROY
            Call SetWindowLong(hwnd, GWL_WNDPROC, lPrevMsgBoxProc)
    End Select

Awesome my friend. That's really amazing.

@Jaafar Tribak if I decide open directly file like this "C:\aa\bb.pdf" instead open drive . how should adjust the code ?

Tom.Jones · Jun 28, 2021

Outstanding.
Really amazing.
Thank you.

Here is an example of how to prompt the user to open directly the "C:\aa\bb.pdf" file :

VBA Code:

Sub Test()

    Const PROMPT = "Click this Hyperlink text to launch your C:\aa\bb.pdf file"
    Const TITLE = "Testing ..."
    Const HYPERLINK_TEXT = "C:\aa\bb.pdf"
    Const HYPERLINK_TARGET = "C:\aa\bb.pdf"
    Const BUTTONS = vbInformation
    Dim lRet As VbMsgBoxResult

    lRet = HyperlinkMsgBox(PROMPT, HYPERLINK_TEXT, HYPERLINK_TARGET, BUTTONS, TITLE)

End Sub

Note; As long as the HYPERLINK_TARGET is a valid target and the HYPERLINK_TEXT string exists within the PROMPT string, it should always work .
So, for instance the following variant will also work :

VBA Code:

Sub Test()

    Const PROMPT = "Open your PDF file"
    Const TITLE = "Opening file ..."
    Const HYPERLINK_TEXT = "PDF file"
    Const HYPERLINK_TARGET = "C:\aa\bb.pdf"
    Const BUTTONS = vbInformation
    Dim lRet As VbMsgBoxResult

    lRet = HyperlinkMsgBox(PROMPT, HYPERLINK_TEXT, HYPERLINK_TARGET, BUTTONS, TITLE)

End Sub

@YasserKhalil,
Can I ask you which excel edition you tested the code in ? Including bitness ie:- x32Bit or x64Bit ?
Also, your OS bitness - Is it Windows 32Bit or Windows 64Bit ?
Thanks.

YasserKhalil · Jun 28, 2021

I am using Windows 10 64 Bit and Office 365 32 Bit.

johnnyL · Jun 28, 2021

@Jaafar Tribak I tested this today for you on Windows 7 - 64Bit machine
Excel 2007 32Bit - Tested fine
Excel 2013 32Bit - Tested fine

Jaafar Tribak · Jun 28, 2021

@YasserKhalil
@johnnyL

Cool !

Thank you for testing and confirming that the code works well across different platforms.

Putting an Hyperlink in a MsgBox !!
