View 10 Replies am trying trying to write some code for a ComboBox that does the following:
1. Allow the user to enter text into the combo box to type entries contained in the list source.
2. Enable autocomplete to assist the user in selecting entries in the list source, both from dropped down state and non dropped down state.
3. Restrict the user from typing an entry that doesn't exist in the list source.
My requirements are:
1. The ComboBox must run some code after a selection has been made or the user has finished typing an entry (not after the focus has been moved to another control)
2. The code must only run once after the user has made a selection from the combobox or has finished typing an entry
The problem: To achieve the above functionality, I had to run code on numerous event's. Sureley there is a better way, here are the events and the reason for the code:
SelectedIndexChanged:This is the code that is run when the user makes a selection. No Mystery here
KeyDown:
Must Run
If e.KeyCode = Keys.Return Then
ComboBox1_SelectedIndexChanged(Nothing, Nothing)
End If

View 7 RepliesI am writing a programme for Payment calculations.I have four textboxes txtPaymentDue, txtDiscount, txtBalancePaymentDue, txtAmountPaid, txtChange
PaymentDue, BalancePaymentDue and Change are calculated by the programme.My requirements are:
1) when i enter Discount in txtDiscount on EnterKeyPress cursor should go to txtBalancePaymentDue wherein it will display the calculated BalancePaymentDue and on next EnterKeyPress the cursor should go to the txtAmountPaid and finally on EnterKeyPress the cursor should move to txtChange.
2) When I enter a digit in txtDiscount it should take it as right to left sequence and it should allow the insersion of digits .......like if i want to type 36.45 then if i type 5 the texbox should immediately look like this 00.05 when i type next digit it should look like this 00.45 likewise when i type next digit it should display 06.45 and finally 36.45.

I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

If we format a value for percent "{0:#%}" then it will become 400%, and this also applies to all the 3rd party controls I've tried. I've used custom format as a workaround for this but perhaps you guys could enlighten me on this one. If a user inputted 4 for example then did the user intended 4% or 400%? If it were me that I would expect the 4 to be 4% rather than 400%.
View 11 RepliesI need to write a program allowing the user to enter up to five passwords at one time. I have the textboxes set the way I need. When the user presses the button, the code should check every password they ve entered, and flag any passwords that are invalid. A valid password includes the following:
At least 6 and not more than 15 characters
At least one uppercase alpha character
At least one lowercase alpha character
At least one numeric character
I'm a little confused about how to check each character of the entered passwords for these conditions.Because it must include alpha characters, I believe I have to do something with ASC and CHAR variables. This is my first post and I need to have this done within a few hours, haha. Help would be awesome.

The above code is from a small program I have written. This test is done on about 30 textboxes I am using for the user to enter number.
The following is the sub routine that is called.
Sub ShowError()
MessageBox.Show(BoxName & " must be a number.")
End Sub
Here is what I want to do but it won't work.
BoxName.Select()
This is so I can put the focus on the different boxes that might contain an error.
