Bold is 'read-only' in VB.NET. This article tells you how to change that.

I have all the event handling in place, functioning fine - but I cannot find how to programmatically set the tab font color. Thank you, thank you, thank you. RE: TabPages - Programmatically setting the font color. Does anyone know how to programmatically install a Font to Windows? We know to copy the font files to the c: Windows Font folder but from there? It seems that you must manually go to the Font folder and double click on the font file to register it in Windows before it will be available to other applications. Delete the font file from fonts directory will uninstall the font. If the font file is in use. Give a message to close all the programs which are using this font and kill the font file.

In VB6, it was dead easy to change a font to bold. You simply coded something like Label1.FontBold, but in VB.NET, the Bold property of the Font object for a Label is read-only. So how do you change it?

Changing Font Properties in VB.NET With Windows Forms

Here's the basic code pattern for Windows Forms.

Private Sub BoldCheckbox_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles BoldCheckbox.CheckedChanged
If BoldCheckbox.CheckState = CheckState.Checked Then
TextToBeBold.Font = _
New Font(TextToBeBold.Font, FontStyle.Bold)
Else
TextToBeBold.Font = _
New Font(TextToBeBold.Font, FontStyle.Regular)
End If
End Sub

There's a lot more than Label1.FontBold, that's for sure. In .NET, fonts are immutable. That means once they are created they cannot be updated.

VB.NET gives you more control than you get with VB6 over what your program is doing, but the cost is that you have to write the code to get that control. VB6 will internally drop one GDI font resource and create a new one. With VB.NET, you have to do it yourself.

You can make things a little more global by adding a global declaration at the top of your form:

Private fBold As New Font('Arial', FontStyle.Bold)
Private fNormal As New Font('Arial', FontStyle.Regular)

Then you can code:

TextToBeBold.Font = fBold

Note that the global declaration now specifies the font family, Arial, rather than simply using the existing font family of one specific control.

Using WPF

What about WPF? WPF is a graphical subsystem you can use with the .NET Framework to build applications where the user interface is based on an XML language called XAML and the code is separate from the design and is based on a .NET language like Visual Basic. In WPF, Microsoft changed the process yet again. Here's the way you do the same thing in WPF.

Private Sub BoldCheckbox_Checked( _
ByVal sender As System.Object, _
ByVal e As System.Windows.RoutedEventArgs) _
Handles BoldCheckbox.Checked
If BoldCheckbox.IsChecked = True Then
TextToBeBold.FontWeight = FontWeights.Bold
Else
TextToBeBold.FontWeight = FontWeights.Normal
End If
End Sub

The changes are:

• The CheckBox event is Checked instead of CheckedChanged
• The CheckBox property is IsChecked instead of CheckState
• The property value is a Boolean True/False instead of the Enum CheckState. (Windows Forms offers a True/False Checked property in addition to CheckState, but WPF doesn't have both.)
• FontWeight is a dependency property of the Label instead of FontStyle being the property of the Font object.
• FontWeights is a NotInheritable class and Bold is a Static value in that class

Whew!! Do you think Microsoft actually tried to make it more confusing?

is there a way to permanently add a Font to a Windows 7/8 PC programmatically?I have read several posts about the AddFontResource DLL-Import, but it doesn't seem to work.

Besides of that, the MSDN Documentation says the font will be deleted after a restart of the computer, unless the font is added into the registry.

How can I install a font permanently? How can I add the font to the registry? Is it always the same name/entry?

I have to add the font dynamically on runtime, because I get the font as soon as the user selects it.

Remark: I know how to add a registry entry. My question is more about the compatibility between Windows XP, Vista, 7 and 8 and the different font-types. Maybe there is a way to start an other exe which installs the font for me.

As you mentioned, you can launch other executables to install TrueType Fonts for you. I don't know your specific use cases but I'll run down the methods I know of and maybe one will be of use to you.

Windows has a built-in utility called fontview.exe, which you can invoke simply by calling Process.Start('Pathtofile.ttf') on any valid TrueType Font.. assuming default file associations. This is akin to launching it manually from Windows Explorer. The advantage here is it's really trivial, but it still requires user interaction per font to install. As far as I know there is no way to invoke the 'Install' portion of this process as an argument, but even if there was you'd still have to elevate permissions and battle UAC.

The more intriguing option is a utility called FontReg that replaces the deprecated fontinst.exe that was included on older versions of Windows. FontReg enables you to programatically install an entire directory of Fonts by invoking the executable with the /copy switch:

Note that the Fonts have to be in the root of wherever FontReg.exe is located. You'll also have to have administrator privileges. If you need your Font installations to be completely transparent, I would suggest launching your application with elevated permissions and approve of the UAC up front, that way when you spawn your child processes you wont need user approval Permissions stuff

I've been having the same issue for the past few days and each solution I found was producing different problems.

I managed to come up with a working code with my colleague and I thought I'd share it for everyone. The code can be found in the following pastebin link:

EDITIn the event this code becomes irretrievable in the future, I have copied it directly into the answer.

According to docs of AddFontResource()

Vb Font Color

This function installs the font only for the current session. When the system restarts, the font will not be present. To have the font installed even after restarting the system, the font must be listed in the registry.

So the best option i found is to copy the font to windows font directory

And then add respective entries in registery,Like

This solution is clean, works without reboot(!) but it does show a 'Installing font..' dialogbox (which disappears by itself).

First, add a reference to system32shell32.dll in your project.
And then, use just these 3 lines of code to install a font:

3 lines of code :)

If you have Visual Studio 2017, you can create a new Visual Studio Installer - Setup Project. I can read your lips on your fingers downloads. You can edit the installer to remove dialog boxes, only leaving the Finish dialog to show the user that it ran OK.

From the File System on Target Machine (in the Visual Studio project), add the special directory called Fonts. Then add all the fonts you want into the Fonts directory. If you look at the Properties of each font you add, you will see that Visual Studio has already assumed you want to register each font.

Compile the project, and you have an MSI with a setup.exe that you can deploy. Of course, you need to run it as an administrator, but other than that, this little program works fast and efficiently. I found that this was the easiest way to install fonts on Windows.
