How to add random numbers between two sets of text vb.net

Okay so I have been trying to make a junk code generator for C++ (new to vb.net just trying to get somewhat familiar with different languages) and I am stuck at being able to call random numbers between two lines of text currently I am stuck at

Private Sub Button4_Click(sender As Object, e As EventArgs) Handles 
Button4.Click
Dim value As Integer = CInt(Int((10000 * Rnd()) + 9999999))
Me.RichTextBox1.Text = (
" float pJunkcode = " + value + ";" +
" if (pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
"If(pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" If (pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" If (pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" If (pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" If (pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";" +
" pJunkcode = " + value + ";")`

The error I am getting is

Conversion from string "pJunkcode" to type 'Double' is not valid.
