Can anyone help with my BalloonToolTips class? It works in Excel 32-bit (W7 and W10) but not in Windows 10 Excel 64-bit, even though it compiles without errors.
It's old VB6 code that I've adapted for VBA (VBA only exposes hWnds for Frames and Listboxes).
So I put any controls other than the above that require a multiline "ControlTipText" in a caption-less Frame with the Userform's bordercolor and I put the control's ControlTipText in that of the Frame.
It's the only way I've found to provide multiline tooltips for such controls.

But they just don't show in Excel 64-bit. Any help would be greatly appreciated.

Take a look at this . It will probably need some further enhancement.

The CtoolTip Class exports two methods: AddTo and Remove and it allows you to set many attributes for the tooltips_class32 control.

Perhaps, I should have used class Properties to set the tooltip attributes instead of using UDTs for storage ... Ayway, see how it goes.

BTW, this works for all controls (even they don't have a hwnd) except SpinButtons and Scrollbars both of which do not expose a mousemove event. You don't need to use container frames.

Thanks Jaafar, that's fantastic, I'll have a look at it tonight.

There was a bug I overlooked in the previous code (post#30) in relation to the TTS_ Style flags .

The code in post#30 makes use of only one single toottip shared between all the controls (using a shared tooltip rather than one tooltip for each control makes things lighter and less prone to crashings ). Therefore, the style flags need to be updated with its specific attributes each time the mouse points to a different control . The code missed this important fact as it was setting the style flags only once during the creation of the tooltip for the first control.

Workbook Update

So please, ignore the previous code and use the following code update with the necessary corrections.

CToolTip Class code:
VBA Code: 
Option Explicit

Private Enum eSTYLE
    TTS_ALWAYSTIP = &H1
    TTS_NOPREFIX = &H2
    TTS_NOANIMATE = &H10
    TTS_NOFADE = &H20
    TTS_BALLOON = &H40
    TTS_CLOSE = &H80
End Enum

Jaafar Tribak said:
There was a bug I overlooked in the previous code (post#30) in relation to the TTS_ Style flags .

The code in post#30 makes use of only one single toottip shared between all the controls (using a shared tooltip rather than one tooltip for each control makes things lighter and less prone to crashings ). Therefore, the style flags need to be updated with its specific attributes each time the mouse points to a different control . The code missed this important fact as it was setting the style flags only once during the creation of the tooltip for the first control.

Workbook Update

So please, ignore the previous code and use the following code update with the necessary corrections.

Jaafar, thanks for this, but your modified code still doesn't compile in Excel 32-bit, it stops on Call CopyMemory(ByVal tTTipData, ByVal DataPtr, LenB(tTTipData)).
CopyMemory is not declared for 32-bit, would it be enough just to add the 32-bit Declare in the #If Win64 Then.... #Else part ?
I tried to add it in your origial code, but then it stopped on Err.Raise Number:=vbObjectError + 513, Description:="Unable to load common controls."
Please advise

OK Jaafar, but in Excel 32-bit it still raises the "Unable to load common controls" error, I can't see where exactly in the cls, I think it's here but I can't be sure:

If FindWindow("tooltips_class32", "MyToolTip") = 0 Then
If hToolTip = 0 Then
With tIccex
.Size = LenB(tIccex)
.ICC = ICC_LINK_CLASS
End With
If InitCommonControlsEx(tIccex) Then

Sorry. Again, that was my mistake. I was passing the wrong ICC to the InitCommonControlsEx api because I blindly copied it from a recent code I posted to load an hyperlink control class.

Anyway, in order to correct this mistake, simply replace the CreateToolTip routine with the following one:
VBA Code: 
Private Sub CreateToolTip()

    Const WS_POPUP = &H80000000
    Const WS_EX_NOACTIVATE = &H8000000
    Const CW_USEDEFAULT = &H80000000
    Const ICC_WIN95_CLASSES = &HFF
    Const ICC_TAB_CLASSES = &H8

    Dim tIccex As InitCommonControlsEx

    If FindWindow("tooltips_class32", "MyToolTip") = 0 Then
        If hToolTip = 0 Then
            With tIccex
                .Size = LenB(tIccex)
                .ICC = ICC_TAB_CLASSES
            End With
            If InitCommonControlsEx(tIccex) Then
                hToolTip = CreateWindowEx(WS_EX_NOACTIVATE, "tooltips_class32", "MyToolTip", WS_POPUP, _
                CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, 0, 0, GetModuleHandle(vbNullString), 0)
            Else
                Err.Raise Number:=vbObjectError + 513, Description:="Unable to load common controls."
            End If
        End If
    End If
  
End Sub

As you can see, I have simply replaced the Const ICC_LINK_CLASS = &H8000& with Const ICC_TAB_CLASSES = &H8 witch is the correct constant needed for registering the tab and tooltip control window classes.

If that still doesn't work, try replacing the ICC_TAB_CLASSES constant with the more generic one : Const ICC_WIN95_CLASSES = &HFF

I have already updated the example workbook in the previous links with this new correction.

Thank you! It now works perfectly in all my 3 environments (W7 Excel 32-bit, W10 Excel 32-bit and W10 Excel 64-bit).

Jaafar, just a quick question. All the tooltips created with your class are positioned at the bottom right-hand corner of the controls.
Could they be positioned either at the top left-hand corner or middle left or center of the control's rectangle?
See screenshot below (btw, I've downloaded xl2bb from this site, but can't figure out how to upload an animation like yours of Oct 28).

The reason I preferred to omit the tooltip position is because it sometimes gets in the way and obscures the control.

Anyway, I have amended the class code so it now offers the user to choose the tooltip position as requested. ( BottomRight being the Default position )

Workbook Demo

Here is this new Enum for setting the Tooltip position: The last enum entry (MousePos) causes the tooltip to show up at the current mouse pointer position.
VBA Code: 
Private Enum eTIP_POS
    BottomRight = 0
    BottomLeft = 1
    TopRight = 2
    TopLeft = 4
    MousePos = 8
End Enum

Set the position when calling the userform as follows:
VBA Code: 
With uTTData
   .cbSize = LenB(uTTData)
   'other UDT entries here ...
   .Position = MousePos   '<== or BottomRight , TopLeft  etc...
End With


And the here is the entire new class code for the record :
VBA Code: 
Option Explicit

Private Enum eTIP_POS
    BottomRight = 0
    BottomLeft = 1
    TopRight = 2
    TopLeft = 4
    MousePos = 8
End Enum

Private Enum eSTYLE
    TTS_ALWAYSTIP = &H1
    TTS_NOPREFIX = &H2
    TTS_NOANIMATE = &H10
    TTS_NOFADE = &H20
    TTS_BALLOON = &H40
    TTS_CLOSE = &H80
End Enum

Private Enum eICON
    TTI_NONE = 0
    TTI_INFO = 1
    TTI_WARNING = 2
    TTI_ERROR = 3
End Enum

Private Type ToolTipData
    cbSize As Long
