Text input issues with Visual Basic

Ok, I'm writing a program in vb. It's simply a text editor. However i've run into a little snag. My program has options to click a button and text is inserted into the text box. I am using this line:

textbox.AppendText (sometext)

Now this code works great if i want the text to be added at the bottom of the page. So here's my question, is there any way to modify or maybe replace this co开发者_JAVA技巧de so that the text is inserted were the cursor is?

Try setting .SelectedText property or using .Paste(String).

Not through the textbox control itself, as far as I know. You will need to use the SelectionStart property to manually insert the text.

textBox1.Text = textBox1.Text.Substring(0, textBox1.SelectionStart) & "INSERTEDTEXT" & textBox1.Text.Substring(textBox1.SelectionStart)

This is assuming you want to insert the text and not just replace it.
