mlblSalvageLife = (txtSalvageLife.Text)
mlblAssetLife = (txtSalvageLife.Text)
mdblTotalDepreciation = mlblInitialValue - mlblSalvageLife
mdblAnnualDepreciation = mdblTotalDepreciation / mdblAssetLife

I changed your code to this and added some labels to the form to display the results:
Imports System.convert
Public Class Form1
Inherits System.Windows.Forms.Form
Private mlblInitialValue As Double
Private mlblSalvageValue As Double
Private mlblAssetLife As Single
Private mdblTotalDepreciation As Double
Private mdblAnnualDepreciation As Double
Private Const cintCol1Start As Integer = 100
Private Const cintCol2Start As Integer = 250
Private Const cintCol3Start As Integer = 400
Private Const cintCol4Start As Integer = 550
Private Const cintColWidth As Integer = 150
Private mfntPrint As Font
Private msngFontHeight As Single
Private msngYPos As Single
'Private mfnrPrint As Font(/code)
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
mlblInitialValue = (txtInitialValue.Text)
mlblSalvageValue = (txtSalvageLife.Text)
mlblAssetLife = (txtSalvageLife.Text)
mdblTotalDepreciation = mlblInitialValue - mlblSalvageValue
mdblAnnualDepreciation = mdblTotalDepreciation / mlblSalvageValue
Me.lblTotalDeprec.Text = mdblTotalDepreciation.ToString
Me.lblAnnualDeprec.Text = mdblAnnualDepreciation.ToString
End Sub
End Class

Being picky but you should use the following:
or
mlblInitialValue = Double.Parse(txtInitialValue.Text)
mlblSalvageValue = Double.Parse(txtSalvageLife.Text)
mlblAssetLife = Single.Parse(txtSalvageLife.Text) mlblInitialValue = CDbl(txtInitialValue.Text)
mlblSalvageValue = CDbl(txtSalvageLife.Text)
mlblAssetLife = CSng(txtSalvageLife.Text) Wayne

Re: Need help getting value of text boxes into variables You should use the following functions when transferring text content to a numeric content
Val()
CDbl()
CSng()
The above will convert the text data into numeric data and then the data will transfer into the variables and then there would be no problem.
Hope the above was useful to you.
