Hide userform title bar, and locking the userform into a relative position on the application.

[superstan2310]

Hi All,

Currently working on a project and I'm trying to get a button located in the bottom right of the application window at all times, and staying there, even if the sheet is scrolled up/down/left/right or if the application window is moved.

I have created a userform (which just contains a command button) and added the below code into it as of this moment, and functionally it is everything I need, except for that fact that the button appears with a title bar, a close button, and can be moved by the user when dragging the title bar. Qualities that I do not wish it to have.

I have seen videos and forum threads about hiding the title bar (and therefore the close button, and prevents people moving it), which clearly shows it is possible, however when I copy the code they use and incorporate it into mine one of three things happen:
1. It outright doesn't do anything.
2. It creates a white box (the size of the userform) in the middle of the screen that just blocks the view of anything beneath it.
3. It stops my code below from working.

There is a bit of code left out of the below, but that is just code in the "ThisWorkbook" section for creating a modeless userform on workbook open, and calling the SetPos macro when the window is resized.

Would anyone be able to help with keeping the functionality of the below code, while being able to remove the title bar? If the code has to be rewritten from scratch, I don't mind.

Option Explicit

#If VBA7 Then
    Private Declare PtrSafe Function IUnknown_GetWindow Lib "shlwapi" Alias "#172" (ByVal pIUnk As IUnknown, ByRef hWnd As LongPtr) As Long
    Private Declare PtrSafe Function SetParent Lib "user32" (ByVal hWndChild As LongPtr, ByVal hWndNewParent As LongPtr) As LongPtr
    Private hWndForm As LongPtr, WbHwnd As LongPtr
    
#Else
    Private Declare Function IUnknown_GetWindow Lib "shlwapi" Alias "#172" (ByVal pIUnk As IUnknown, ByRef hwnd As Long) As Long
    Private Declare Function SetParent Lib "user32" (ByVal hWndChild As Long, ByVal hWndNewParent As Long) As Long
    Private hWndForm As Long, WbHwnd As Long
#End If


Private Sub UserForm_Activate()
    WbHwnd = Application.hWnd
    Call IUnknown_GetWindow(Me, hWndForm)
    Call SetParent(hWndForm, WbHwnd)
    Call SetPos
End Sub

Public Sub SetPos()
    Me.StartUpPosition = 0
    Me.Left = Application.Width - 150 - Application.Left
    Me.Top = Application.Height - 125
End Sub

Hi. Two things spring immediately to mind. First, you will need to make sure that the userform's ShowModal property is set to False, and I suspect that the code above would then need to be placed not in the Activate event but the Initialise event, if that makes sense.

Making the UserForm modeless will then enable you to click on other things, like the worksheet and input data, etc. The consequence though is that the Activate event doesn't fire, I think. Not at a computer, but I feel the answer is something along those lines.

I have a workbook open event that creates the userform as vbModeless already (not sure if thats technically the same thing as ShowModal set to false), see below for the entire workbook vba section as it is currently, and the userform_activate sub still runs so unless any title bar related macro just doesn't work on activate (and requires initialise instead for some reason) I would assume it's unfortunately neither of those two things.

Private Sub WorkBook_Open()
UserForm1.show vbModeless
End Sub

Private Sub Workbook_WindowResize(ByVal Wn As Window)
Call UserForm1.SetPos
End Sub

Just seen this. Have you found a solution?

Besides Dan's suggestion regarding the userform needing to be modeless, you will need to manage the Initialize and activate events so they don't clash when removing the the userfom caption and setting its position.

I remember writing some vba code to make buttons float on the screen (over the worksheet) but I didn't plan to lock them in a relative position to the application.

I will see if I can achive this and post the code here.

I have not found a solution yet. Admittedly I have been working on the rest of the project to move things along, in hopes that by the time I get back round to the title bar situation someone here might have found a solution.

The code I'm using works for everything functionality wise, It just doesn't want to work alongside what seems to be the most used methods of removing the userforms title bar. I honestly wouldn't be surprised if the IUnknown_GetWindow function is somehow clashing with the title bar code.

It already is modeless, and the activate event worked fine, although I have since changed to initialise to see if it would work with the title bar stuff, it did not work either, but otherwise continues to run my code the same as activate did.

I will say that I have now moved the declarations to a module and made them public instead of private so that multiple userforms can take advantage of them without having to re-write it out every time. In case that somehow affects things.

Ok- Here is a generic function that creates dynamic floating button(s) on the fly ... Below is the signature of the core\worker function:

Public Function AddFloatingButton( _
ByVal AnchorCell As Range, _
ByVal Width As Double, _
ByVal Height As Double, _
ByVal ParentWindow As Window, _
ByVal lpClickFunc As LongPtr, _
Optional ByVal PosRelativeToParentWnd As Boolean, _
Optional ByVal FloatAccrossAllSheets As Boolean _
) As MSForms.CommandButton

By default, the function doesn't lock the button in a relative position to the application window so, in your case, you want to set the PosRelativeToParentWnd optional parameter to TRUE (This is shown when running the Test2 Macro) ... When this optional parameter is set, the floating button will move along with the parent window each time the application\workbook window is resized.

Since the function returns a native MSForms.CommandButton object, you can set the button properties at will once it is created. This is very convinient and intuitive.

The floating buttons share the same CLICK event but you can use the Button argument to know which button was clicked.
'// Generic Callback Click function:
Sub Button_Click(ByVal Button As MSForms.CommandButton)
MsgBox "You Clicked: [" & Button.Name & "]"
End Sub

There is also a right_click popup menu to close each button individually.

Written and tested in Excel 2016 x64bit and Excel 2013 x32bit.

Hi again Jaafar, thanks for the code, with it's help I have been able to work out the code at the very bottom of this reply to meet what I need.
The only issue I have encountered is this basically keeps the userform window the same size, and moves the contents of the window up and to the left to fill the gap. (see below for example)

Before After

While I can remove this area by adding in:

Me.Width = Me.Width - X
Me.Height = Me.Height - Y

After the "Call Declarations.RemoveTitle" line, and replacing X and Y with values that I find look good, and this works for other userform I currently have in the file, but the above example doesn't want to get narrower than it already is. (see below)

This seems to be due to some minimum required width or something. And the only way I could get around this was to make the button wider than the actual userform window in the vba designer. (see below)

Design Screen Spreadsheet

Would you happen to know if there is a way to make it so when the title bar is removed the remaining userform looks just like it would on the vba designer example below, but obviously without the blue window around it? This would save me having to manually change the width and height of each userform going forward, and allow anyone to visually redesign the userforms if they want to without having to interact with the code side of things.

Userform code

Private Sub UserForm_Initialize()
    WbHwnd = Application.hwnd
    Call IUnknown_GetWindow(Me, hWndForm)
    Call SetParent(hWndForm, WbHwnd)
    Call Module.RemoveTitle
    Call SetPos
End Sub

Public Sub SetPos()
    Me.StartUpPosition = 0
    Me.Left = Application.Width - 161 - Application.Left
    Me.Top = Application.Height - 125
End Sub

Module code

Option Explicit

#If VBA7 Then
    Public Declare PtrSafe Function SetWindowLong Lib "user32" Alias "SetWindowLongPtrA" (ByVal hwnd As LongPtr, ByVal nIndex As Long, ByVal dwNewLong As LongPtr) As LongPtr

    Public Declare PtrSafe Function IUnknown_GetWindow Lib "shlwapi" Alias "#172" (ByVal pIUnk As IUnknown, ByRef hwnd As LongPtr) As Long
    Public Declare PtrSafe Function SetParent Lib "user32" (ByVal hWndChild As LongPtr, ByVal hWndNewParent As LongPtr) As LongPtr

    Public Declare Function IUnknown_GetWindow Lib "shlwapi" Alias "#172" (ByVal pIUnk As IUnknown, ByRef hWnd As Long) As Long
    Public Declare Function SetParent Lib "user32" (ByVal hWndChild As Long, ByVal hWndNewParent As Long) As Long
    Public hWndForm As Long, WbHwnd As Long
#End If

Public Sub RemoveTitle()
    Const WS_CAPTION = &HC00000
    Const GWL_STYLE = (-16)
    Call SetWindowLong(hWndForm, GWL_STYLE, GetWindowLong(hWndForm, GWL_STYLE) And (Not WS_CAPTION))
    Call DrawMenuBar(hWndForm)
End Sub

Not sure why I can't edit my previous reply, but the "Before After" and "Design Screen Spreadsheet" bits for the photos should be "Before / After" and "Design Screen / Spreadsheet", I tried putting a bunch of spaces in to make them more spaced out rather than adding the /'s, but I guess this forum removes the excess spaces. And also doesn't let you edit your previous replies.

Hi again, I've found something that should be good enough.

Private Sub UserForm_Initialize()
    WbHwnd = Application.hwnd
    Call IUnknown_GetWindow(Me, hWndForm)
    Call SetParent(hWndForm, WbHwnd)
    Call Module.RemoveTitle
    Dim h, w, h1, w1
    h = 0: w = 0: h1 = Me.Height: w1 = Me.Width
    For Each Control In Me.Controls
        If Control.Visible Then
            If Control.Top + Control.Height > h Then h = Control.Top + Control.Height
            If Control.Top < h1 Then h1 = Control.Top
            If Control.Left + Control.Width > w Then w = Control.Left + Control.Width
            If Control.Left < w1 Then w1 = Control.Left
        End If
    Next Control
    If h > 0 And w > 0 Then
        Me.Width = w + 2 * w1
        Me.Height = h + 2 * h1
    End If
    Call SetPos
End Sub

Personally I would have preferred to just do Me.Width = Me.InsideWidth as well as Me.Height = Me.InsideHeight, as then if someone didn't want the userforms to have the same size blank areas on the top/bottom and left/right then they could, but it didn't seem to want to work as advertised, instead of setting the height and width to what is shown within the userform, it just seemed to remove the width/height of the right/bottom borders respectively. I.e. there was a sizeable blank area underneath that is the same size as the title bar, and a small blank area to the right that is the size of the left border.

I even confirmed this by writing a msgbox to pop up and tell me the height/width of both .Height/.Width and .InsideHeight/.InsideWidth, and the difference was 4.5 for all values, despite thinking that the heights should be more than that due to the title bar.

@Jaafar Tribak If you can somehow think of a way to get InsideWidth and InsideHeight to work, please let me know, otherwise, if by the end of the week there are no further responses, I will mark this thread as resolved and set Reply #6 as the resolution.

@superstan2310
I am not sure I fully understand. It seems to me that you are adding the commandbutton @ design time while my code adds the commandbutton for you at runtime. You just need to specify the button location, size etc in the parameters of the AddFloatingButton and it should do all the work for you.

Did you download the file demo I provided in post#6 ? And if so, did it work for you as shown in the animated gif in post#6 ?

Edit:
@Dan_W
Did you test the code in post#6 ? Did it work as advertised?
