how to create instance of a class which is inside a app_code folder's folder

It doesn't matter where your class file reside.
The only important aspects are the class name(usually when it is in a Folder, Visual Studio puts the name as FolderName_ClassName), the access modifier.

What is the problem ? It doesn't matter. I don't believe you can use VB and C# files in your project, you can only mix them up for the pages. But, if it compiles, then I am wrong. Either way, the classes in the project, are visible to all languages in the project. Did you actually try anything before asking this ? Is so, and it doesn't work, post the code and the error so we can try to work out what you're doing wrong.

Does it compile properly after putting the C# and VB Class in different folder? Did you set the web.config Subdirectory Section like
<Compilation>
<codeSubDirectory>
....
<add directoryName="CSharpFolderName"/>
.....
</codeSubDirectories>
</compilation>

Then try to access the call method using object that class. Also check the class access modifier.

When I press the button ("btnInsert") Jscript Debbuger gives me this error on the javascript code statement " var saveText = ctrl.value; " on the line 644 with yellow highlighted.

ctrl is therefore null. So, I assume that means you're setting it with document.getElementById, and not checking the return value. Odds are that you're using the server side ids instead of using the clientId property to get the client side id's for your script.

Which browser are you using ? It works fine in IE but firefox. It seems detecting text selection in firefox[^] is different. It may fail because of this reason.

Make sure that your text box control(FreeTextBox1) is enabled and visible. if not then first enable it then set the focus otherwise it gives an error.
