Vba Error Message Dialog Box
up How to create an error message box for an empty text box: VB 2010 Express up vote 2 down vote favorite I am taking VB this semester, and while it is not required for this particular assignment, I am curious how I can create a MessageBox error if a text box is left empty. We just covered using the Try/Catch statement, and vba error message 400 I have successfully created MessageBoxes for text boxes whose text is only numeric. For example, a user must enter a name, and two numeric amounts. I am trying to create an error if the Name text box is left empty, stop the program from calculating the two amounts and return the insertion point to the Name text box. Is there an easier way to do this? The If/Then statement I currently have does not stop the program from calculating (I am just starting out so go easy on me): Private Sub CalculateButton_Click(sender As System.Object, e As System.EventArgs) Handles CalculateButton.Click 'Declare Variables Dim SellingPrice, CostValue, Commission As Decimal 'Test to see if a name was provided the NameTextBox If NameTextBox.Text = "" Then MessageBox.Show("Please enter a Salesperson's name", "No entry", MessageBoxButtons.OK, MessageBoxIcon.Error) With NameTextBox .Focus() .SelectAll() End With End If 'Test if Numerical data was entered for SellingPriceTextBox Try 'Convert Selling Price SellingPrice = Decimal.Parse(SellingPriceTextBox.Text) 'Test if Numerical data was entered for CostValueTextBox Try 'Convert Cost Value CostValue = Decimal.Parse(CostValueTextBox.Text) 'Calculate the Commission earned Commission = Decimal.Round(COMMISSION_RATE * (SellingPrice - CostValue), 2) 'Format and display results TotalCommissionLabel.Text
