I've come across an error I'm not quite sure how to get rid of, I've got a listview with listview items making up the grid, I've got values coming from a database populating the cells however if there are any null values(in this case, there's null values in the date) it crashes my program. I'm not quite sure of a way to allow the listview to have null values in it, I figured it would default allow it but that's not the case.[code]....

This code works, as is, on my system. Problem lines are commented out. The last three commented lines are the problem.It creates the objects alright but a line that should send a message into the list box doesn't work. I am almost sure that the problem is in passing information into the sub routine. Forgive my use of ALL CAPS as it helps to see my comments on comments. A few comments in passing information to SRs would be helpful.
Also, how it is that I can comment out the .Name option and it still works?(I hope that this shows up properly. If it ends up as a big useless paragraph, I will repost it after learning how to do it properly.

Let's say I have 50 cars and I created 6 attributes for each of the 50 cars (therefore 300 total variables and values for those 300 variables). These attributes are created and valued based upon the following structure:
Car1Name = "Dark Red Car"
Car1Color = "Dark Red"
Car1DoorCount = 4
Car1Cost = 10000
Car1Appeal = 10
Car1BoughtStatus = False
Car2Name = "Bright Red Car"
Car2Color = "Bright Red"
Car2DoorCount = 4
Car2Cost = 11000
Car2Appeal = 8
Car2BoughtStatus = True
and 48 others of similar structure/syntax
How do I take a a module with these variables and values and populate them into a listview within a form such as Form1 and ListView1 without continuously going into listview's UI and manually entering the data? The goal is to show the USER a list of 50 cars, their color, door count, cost, appeal, and purchase status.

I have a ListView of 4 columns, one of which is a monetary value.I am trying to add these values of 'selected' rows. I can add ALL row's values - but not selected rows. The code that I use actually highlights all the rows that contain the string that is looked for but the result is not correct. Let me explain: Say I am looking for all the rows that contain the word "Special" and that it is in 4 rows. The 4 rows are highlighted but the result is the value of the first row highlighted multiplied by the number highlighted. In a Console.WriteLine I find that the same numberRow is shown 4 times. I can't work out how to get each row's value.[code]

This is kind of a brain twister. First, what it involves. I'm writing an application that is working with values sent to and received from an 8 bit micro-controller. There are 8 bits of specified values. Here they are. bit1 = 1, bit2 = 2, bit3 = 4, bit4 = 8, bit5 = 16, bit6 = 32, bit7 = 64 and bit8 = 128.I made a routine that uses 8 checkboxes to add the values for sending them to the micro-controller. That wasn't too hard. In my appp there are 8 checkboxes. Each checkbox assigns one of the specific bit values to a variable (or subtracts it when unchecked). The total of the variable is then displayed in a textbox and ready to send.Now the hard part that ed to take any number between 0 and 255 apart in values that will be a combination of the numbers (1,2,4,8,16,32,64,128) above and show each checkbox which is assigned those numbers to be checked.
