I'm working on a project for my VB class at school. I am creating a form with several inputs and it calculates the total amount owed for a car sale. I have a text box for input of the TRADE IN VALUE of a car. the program is looking for a numeric input. If there is no trade in, how can i get this box to default to 0.00 so it doesnt error the program?

Here is my case:I have a richtextbox called Rtb1 I have the text property for this control set to "ThreadAmountEdit=[Thread Amount]" This was set through the RichTextBox Tasks function, by clicking the control and selecting the little arrow in the top right corner. In working on my form, I edit the text "[Thread Amount]" of the rich text box to "45". What I need is to be able to reset Rtb1 back to default ("ThreadAmountEdit=[Thread Amount]")on button click.
I've tried: Rtb1.Refresh() which doesn't appear to do anything I've also tried Rtb1.ResetText() which completely clears the textbox.
i have a datagridview binded with the datatable via its datasource property....now i want to add the Amount column of the dgv and display the total amount in the textbox,if the amount is greater than a certain value then i want the cell to coloured red so i did this code and it worked great:
Dim i, j As Integer
For i = 0 To DataGridView1.RowCount - 1
j += Me.DataGridView1.Rows(i).Cells("Amount").Value
Next
[code]....
but my problem is that i want the red colour of the cell to blinkafter every 2 seconds....how to do this?i need to handle the timer tick event for this but i am not able to do this.....

End Sub
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]

View 1 RepliesI am working on an app now, and I need it to read text from a .txt file, but there's more. Here's what I want it to do:
Dim text as string
Find "file.txt"
text = line1 in txt file
Do something
text = line2 in txt file
Do something
text = line3 in txt file
Do something
And so on, until there are no more lines to read. I have searched, but all that I have found requires you to preprogram the amount of lines in the .txt file. I want to be able to add lines later without having to go into the code and add more.
I have this code in Timer1:
