Hello,

I've created a Font ComboBox, but now i am trying to have the selected font change the highlighted text. How could I go about accomplishing that. Here's the code that I have to show the font:



Any help would be great thanks.

Maybe I need to give a little more explanation as to what I am trying to accomplish. When working with Microsoft Word, there is a combobox on a toolbar that allows you to change the selected font of your original text to another selected in that combobox. all this without having to go through the process of the FontDialog(). Does anyone have an idea of how i can accomplish that task? Any and all help would be great. THANKS!!!

I think this will help you out.

No, I've been to that site a while back and that's not what I was thinking of. I was thinking of utilizing a combobox, that lists all of the fonts that is installed in the fonts folder and when you select a specific font, the RichTextBox.SelectedText (or SelectedFont, not sure exactly) will change to that particular selected font from the combobox. What do you think? Thanks.

The concept is exactly the same, the only difference is that you will select the font name from a combo box instead of providing it in your code.

Do you know how to read the names of the fonts on your system and load them into a combobox?

No I don't actually, if you could help me that would be great. Also, I am a student of learning, and if you could explain the steps (to the best you can) that would also be great. Thanks.

Reading the font name is actually quite easy. You will simply need a FOR loop to iterate through all of the True Type fonts on your system. You would put this loop inside your Forms Load event. It will populate, in this case ComboBox1, with all the fonts in your system.



You could use the SelectedIndexChanged event of the combobox to cause the font to change. Which means when you SELECT, by clicking the font name in the combo box it will change the selected text automatically. You would put the following line of code inside the SelectedIndexChanged event of your combobox.

Now comes the important part causing the selected font in the RichTextBox to change.


In this example I am supplying two parameters to the New Font. The first parameter is the Text, which is the font name, of the combobox and the second parameter is the size of the font. I chose to keep it static for this example at 12 points.

But you could create a second combobox which contains all the different font sizes in points.
In which case the code would look like this:


You need to convert the text value into a integer value for the point size of the font, hence the CInt.

Thats all you need to change the font of selected text in a RichTextBox.

Here is a screenshot of a simple one I put together for this example.

Jayman9, that looks really simple, I will try that tonight when I get to my personal computer. Thanks.

Also, another question, that goes along the same line...the style box that is within Microsoft word, would technically follow the same function as you described? Thanks.

Yes it is exactly the same.

Sweet, thanks man!

Jayman9, the changing of the fonts worked perfectly, but for some reason, when i try to implement the code to change the selected text size, it's giving me an error. But the error also occurs when I try to change the selected text's font and it would give me an error with this particular code: Me.RichTextBox.SelectionFont = New Font(Me.FontBox.Text, CInt(Me.SizeBox.Text))

Here's the code that I used, which you provided and for somereason it's not working, what do you think's going on?



Thanks.

Oops, my bad I forgot the SelectedIndexChanged method will fire during the load. And since there is no values in the second combobox while it is filling the first combobox, it is causing an exception.

Simple solution though, just create a module level Boolean variable to be set to true only when the form is loading, the last statement in your Load event will be to set it to false.

Then enclose the statement inside the SelectedIndexChanged method in an IF statement that will only allow it to run if the boolean is false.

One last thing I forgot to tell you since you now have two seperate comboboxes you want the SelectedIndexChange method to handle both of them. To make one SelectedIndexChanged method handle more than on combobox just add it after the word Handles as I've done.



Here is the code I put together so you can compare.


Did you notice this bit of code, it sets the comboboxes to the current font and sets the font size to 10.

Jayman, thanks, it's working now and I understand to functions of it as well. One quick question and then we'd be done. Is there a wayto have it automatically show the font and size in their respective combobox the moment the form is loaded? Right now it automatically fills in when you click on the comboboxes. Any thoughts? Thanks.

See the end of my previous post for your answer and note where it is located in the Form Load event.
