Jul 6, 2010I want the program to check the number of items in a list box, then send use that number to form a FOR loop and send each to the serial port individually. It actually sends everything, but the program always crashes after the last one saying that the sdprintcount variable is an invalid number for the index. I don't get it as this happens no matter how many items are in the list, and it always crashes on the last one. It sends it, but then it says the index number is invalid.

Filter A Dataset Using A Number Different Inputs, Selected By A Number Of Check Boxes?
Mar 3, 2010I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

ATM System - Check Card Number Matches Up To The Users PIN Number
Mar 13, 2009I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.

Jun 20, 2012For my ToDo list I need lots of variables to store data in.Each item of the list has 3 strings in it: Activity, start time and end time.To make multiple tasks in my ToDo list I think it's the most usefull if I use this: 'For x = 0 To 1000', so on the launch it will make 1000 variables to store my data in.But for the 3 string for extra info I need something like this:
x.a

x.c
Where x is the integer, and a, b and c are the 3 strings. If I try to do this I will need to do 'Dim a, b, c as String', but that way it will not understand x.a x.b and x.c If I do 'Dim x.a, x.b, x.c as String' it gives me an error, because x.a is not a String...

VS 2005 Configuring A Datasource Value Member & Display Member
Jan 6, 2011I have 2 tables Table A & Table B Table A has the table values that I want to be populated in a datagridview control.The challenge is that column 1 in table A contains an ID(foreign key) to a name field that is a located in table B. I need the datagrid to have the first column be a combobox that displays the names(from Table B) that are already in table A via the ID's, but reference the populating values from Table B. So that when you bring down the combobox you would be choosing from Table B data but populating table A with the ID and you would see a name there instead of an ID.[code] How do I populate my DS dataset with Table B? And how can I create a link to these two tables using a bound datagridview control?

Check For A Number In A String?
Jun 21, 2010I'm reading data in from a comma-separated text file and storing the data in an array for later use. Some of the values are to remain as strings, and I need to convert some to integers, for which I was trying to use, for example, integer.parse(ar(0)).
My problem is that the string values are randomly distributed through the text file, so I need to be able to test whether the string can be converted at all before doing the conversion.
Check If A .NET Decimal Value Is A Whole Number?
Aug 20, 2010I have class representing a unit of measure with a Decimal as the numeric. Just to simplify things for this example, let's say I'm representing centimeters. I'd like to implement a ToString() method for this class. The thing is, if the numeric value is a whole number I'd like to just display the decimal as an integer. Otherwise, I'd like to keep it as a decimal. So, for example, 10.5D centimeters would display as "10.5cm", but 7.0D centimeters should display as "7cm". I'd like this to be fast and simple to read. I have a working solution, but it seems like there should be a better way.Here's a contrived example showing my first crack at it:
Public Property Units As String = "cm"
Public Property NumericValue As Decimal = 10.5D
Public Overrides Function ToString()
