View 12 RepliesI need a regular expression that can validate that a string is an alphanumeric comma delimited string.
Examples:
123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid
This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$
I'm working in Microsoft Access attempting to concatanate the results of a query into a single string. The code looks like this:rtn = Trim(rs.Fields(0).Value) Trim$(rs.Fields(1).Value)When I display the string in a list box, I only see the value for Fields(0) I cannot see the value for Fields(1).When I run the code in debug mode, I can see the value of rtn and it contains these non-alphanumeric boxes like this:"Earth4[] Admin[]" (where [] indicates the non-alphanumeric character)What can I do to cleanup the string, remove the [] and then display in my list box?

I have a string array of size 51 CardListIn() representing randomly ordered cards in a deck {1d, 2d, ...14c} e.g. 9d = 9 of diamonds and so on. I then have 52 text boxes for user input. These have been put into an array of text boxes as so:[code...]
I want to search my original string array for any cards the user may input in any of the textboxes and then delete those entries from the string array.So say the user enters "1d" in one of the textboxes, I then want that removed from the string array.
I'm parsing through both the array and the text boxes fine, but for some reason that I cannot fathom, it doesn't find a match. The string array definitely contains "1d" and the textbox definitely contains "1d", but it doesn't register as a match. I've tried using Val() for the string array and the text boxes, but then it removes every entry beginning with a 1, e.g. "1d", "1h", "1c" & "1s".
Basically, for each character in a charArray created from the string to split, if the character is a letter, digit, or hyphen, I append it to a temporary string. When I see a split character or the last character, and the temporary string has value, I add it to the collection to return.
For i As Integer = 0 To (charArrayLength - 1)
charToInspect = CChar(charArray.GetValue(i))
If IsLetterOrDigit(charToInspect) Or charToInspect = hyphen Then

textBox1.ReadOnly = True

Im trying to change or increment the month value of the datetimepicker using a command button. I tried to use the sample code from MSDN site but I was only able to increment once. I want to increment the value of the month everytime you click the command button. Do I need to use a loop statement? If so, how do I do that? I used this code below which can only increment or change the month value once but when you click the button again, no changes will be shown.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
'DateTimePicker2.Value = New DateTime(2001, 10, 20)
DateTimePicker2.Value = New DateTime(DateTimePicker2.Value.Year, DateTimePicker1.Value.Month + 1, DateTimePicker2.Value.Day)

the damn thing keeps returning 1 instead of 0. I do know i can simply change to 1 and be off the issue. but if is that easy to generate 1 the isnt easy just to break it. oh yeah the whole thing hangs when i generate the code? if i loop it, its able to get a 0 but i cant take the key thats in the loop?
