Introduction - Transparent UserForm
If you’ve been searching for a way to make a VBA UserForm with a transparent background, you’ve finally come to the right place. In this tutorial, I’ll show you how to make the background of your UserForm transparent and I’ll illustrate how you can use these macros to make the BackColor or ForeColor of your controls transparent, too.
That’s right. It will look like the controls on your UserForm are sitting right on top of the Excel grids!
If you want to slowly fade your userform in and out instead, check out my tutorial on fading your VBA userform.
Example - Transparent UserForm
'PLACE IN YOUR USERFORM CODE Option Explicit Private Declare Function FindWindow Lib "user32" _ Alias "FindWindowA" ( _ ByVal lpClassName As String, _ ByVal lpWindowName As String) As Long Private Declare Function GetWindowLong Lib "user32" _ Alias "GetWindowLongA" ( _ ByVal hWnd As Long, _ ByVal nIndex As Long) As Long Private Declare Function SetWindowLong Lib "user32" _ Alias "SetWindowLongA" ( _ ByVal hWnd As Long, _ ByVal nIndex As Long, _ ByVal dwNewLong As Long) As Long Private Declare Function DrawMenuBar Lib "user32" ( _ ByVal hWnd As Long) As Long Private Declare Function SetLayeredWindowAttributes Lib "user32" ( _ ByVal hWnd As Long, _ ByVal crKey As Long, _ ByVal bAlpha As Byte, _ ByVal dwFlags As Long) As Long 'Constants for title bar Private Const GWL_STYLE As Long = (-16) 'The offset of a window's style Private Const GWL_EXSTYLE As Long = (-20) 'The offset of a window's extended style Private Const WS_CAPTION As Long = &HC00000 'Style to add a titlebar Private Const WS_EX_DLGMODALFRAME As Long = &H1 'Controls if the window has an icon 'Constants for transparency Private Const WS_EX_LAYERED = &H80000 Private Const LWA_COLORKEY = &H1 'Chroma key for fading a certain color on your Form Private Const LWA_ALPHA = &H2 'Only needed if you want to fade the entire userform Private Sub UserForm_Activate() HideTitleBarAndBorder Me 'hide the titlebar and border MakeUserFormTransparent Me 'make certain color transparent End Sub Sub MakeUserFormTransparent(frm As Object, Optional Color As Variant) 'set transparencies on userform Dim formhandle As Long Dim bytOpacity As Byte formhandle = FindWindow(vbNullString, Me.Caption) If IsMissing(Color) Then Color = vbWhite 'default to vbwhite bytOpacity = 100 ' variable keeping opacity setting SetWindowLong formhandle, GWL_EXSTYLE, GetWindowLong(formhandle, GWL_EXSTYLE) Or WS_EX_LAYERED 'The following line makes only a certain color transparent so the ' background of the form and any object whose BackColor you've set to match ' vbColor (default vbWhite) will be transparent.

Tutorial - Transparent UserForm
Step 1: Create your UserForm
If you made it this far, you probably already have a UserForm designed. If not, go ahead and do it now.
Since today is the 4th of July, here’s what my UserForm looks like:
It’s a very simple UserForm. All I have in mine is a picture and a little birthday message for the United States of America.
If you want your user to be able to click around your spreadsheet while your transparent UserForm is displayed, you’ll need to set the ShowModal property of your UserForm to false.
This is really cool because people will be able to click cells right behind where your UserForm should be. They’ll even be able to click through the holes in your label text!
Step 2: Set your Transparent Colors
I set up the macros so, by default, any object normally shown as white will be transparent, or clear, when the UserForm is shown. This excludes the background of the UserForm which will ALWAYS show up transparent the way I built the macros and it excludes any white that appears inside of pictures.
In my example, I want the color behind the text label to show up clear. I want it to look like the text is written right on top of the Excel cells.
To make that happen, I’ll select the label in the UserForm and set the BackColor property of the label to white, like this:
You can set the ForeColor to white and the BackColor to a different color if you want the letters themselves to look invisible.
Note: There’s a way you can change the color you want to be transparent. I’ll explain how in Step 3. This is important if you don’t want your textboxes and listboxes to automatically look clear
Once you’ve set all the controls you want to be transparent by changing their color to white, continue to Step 3.
Step 3: Add the Macros
Right-click your UserForm and select “View Code.” Copy and paste the example macro into the UserForm code block.
The most challenging part of this macro was removing the little border that appears around your UserForm. You don’t even notice it’s there, but once you make the background transparent, you’re left with a border showing the outline of your UserForm. It was very ugly!
One thing to notice is that the macro I provided will not work on a 64-bit version of Excel until you add the PtrSafe keyword after the “Declare” and before the “Function” in all the user32 declarations at the top of the macro.
Change Color You Want to be Transparent
If you already set the color of each item you want to become transparent to white, you’re all set.
If you set it to a different a color, you’ll want to find the UserForm_Activate procedure and add the color you want to become transparent as a second argument in the call statement to
MakeUserFormTransparent Me, vbBlue
The long number representing the RGB code of your transparent color can also be passed, like this:
MakeUserFormTransparent Me, RGB(0, 0, 255)
Step 4: Launch UserForm
Here’s where you get to see all your hard work pay off. Launch your UserForm! You can launch it by pressing F5 or hitting the play button in your Visual Basic Editor.
If you made a UserForm like mine, you’ll have to click the text or the flag and hit Alt-F4 to exit the form since I didn’t include an unload me button.
Here’s what mine looks like when it’s launched:
Remember earlier how I said if you set your ShowModal property to false, you can click right through the transparent portions of your UserForm? Here’s proof that I wasn’t just making that up!
I clicked right through the triangle in “4” and selected the cell beneath it. If you click directly on the red text, it selects the UserForm instead.
I don’t know how you feel, but I’m feeling pretty excited about this project! VBA is known for having such. boring. user-interfaces. The ability to make transparent backgrounds on your userforms like this lets you add just a little bit of flair to the otherwise boring world of userforms.
