I am using an input box. In tat am getting the number as input. When the user presses OK the program is workin. But when I press the cancel button am getting a error message
" Conversion from String "" to 'Integer' type is not valid "
If i press cancel I need the program to end. and also i want to know how to move to other form when i press cancel in input box
Is there a way to repeat two popup input boxes (in succession) until the user presses cancel?
Dim hours As Integer
Dim letterGrade As String
Do
hours = InputBox("Total credit hours", "Total credit hours", )
letterGrade = InputBox("Letter Grade", "Letter Grade", )
Loop
The input boxes continue to repeat but when I hit cancel nothing happens... I'm sure I'm missing something to tell it when I cancel to go back to the MainForm I just don't know what it is.....

If Not IsNumeric(textbox1.Text) Then
KeyAscii = 0
End If
I learned in MSDN and wrote those code,but it doesn't work. This code " KeyAscii = 0" it's not correct, I just want to cancel the input, for instance,if user input 1a, then "a" will be not inputted into textbox, but "1" will leave.
i want to cancel the input on textchange event depending on a condition, how? for example, as user type in textbox, it fires textchange event, in that i want to do some condition testing, if value is true then accept new character or cancel the new input.
View 5 RepliesI want to make it so when cancel is used it exits the loop but I need the Input as a decimal.
Do
txtItems.Text = intCounter.ToString
intCounter = intCounter + 1
msgInput = CDec(InputBox("Enter Item Price", "Item Price", ""))
decSubTotal = msgInput + decSubTotal
txtItemPrice.Text = msgInput.ToString("C2")

Handles Trackbar.ValueChanged
txtYears.Text = Trackbar.Value

This is the code for the trackbar. At the moment as the user moves the trackbar it inserts the value into the textbox. I want this to work in reverse also. user inputs value into text box, trackbar moves.
I know it is possible as my professors program does this.

What I need is a code that can read from database (*.accdb). Form example if I select LG from Form4, it should read from a table from the database the price of
the LG, then we press "save", then should return to the Main Menu, then we select, for example, Scanners from the Main Menu that will take us to Form5. There we select, for example 24", that should take the price again from the data base and
add it, after save, to our first LG price, and return back to the Main Menu, and so on. The total price should appear in a new form, form7, after clicking (Total Price).

View 1 Replieswhat's the best way to stop a form from displaying in its Load event.I initialise a form using the following code:
Dim MyForm as new MyCustomForm
In the Load event of MyCustomForm, I ask the user to select a folder and use that to populate a listbox on the form.folder.If the user presses Cancel instead of selecting a folder, I don't want to display the form. Right now, I just call Me.Close in the Load event, but that still causes the form to briefly appear and disappear in the background. Also do I need to call Me.Dispose?
