so here instead of directly using > and +, Can I use the variables OP1 and OP2 somehow. May be I can put the entire string from "If..... NUM1" in another variable as text string and then execute that variable.
I have a program where I open files and I store the location as a variable so I can reopen them later on. It works much like MS Word does, where it shows the names on the side and when I click it and open, it will open the file. Mine is a little different because it will store large numbers of file names in a list box because people are usually going to open folders full of files. The initial way I did it had the path name stored in a list box and it would open the file using that path. I decided it was a bad idea and I tried to use just the name of the file. However, I ran into a problem with the code that I was using.
Code:
If its checked, it will open the selected item from the list box instead.
If CheckBox1.Checked = True Then
'for all the indexes of the saved location record of array, if the selected item is found, then open that file
For counter = 0 To SavedLocations.GetUpperBound(0)
[code].....
So as you can see, what I have is it decides whether you opened from the list box or not. If it is not from the list box, it opens it up fine. It adds the information to the list box and stores some information in an array so I can access it later on. If it does open from the list box, then it will search for the file name in the array. If it finds it in the array, it will proceed to open the file using the directory. There is no else clause because it should be finding it 100% of the time.
The error I get is that parameter cannot be null. Filename2 never seems to get assigned, which means it's not finding the value in the array. I've tested and the value is in the array and the values are the same values.

I have two aspx pages. I need to send a textbox(record_id) value as a parameter from page1.aspx to page2.aspx to be utilized within a SqlCommand query in the VB code behind page.

I have a file which is opened and the bytes are loaded into a class.The file needs to be split into chunks, and there is a header which gives the locations and sizes of the chunks.Should I (upon opening the file) split the file into chunk sand store each chunk in an array of variables And then when I want to access the data in the chunks I just use the array.
or store all the chunks in one variable together and then when I need access to the chunks get the location and size of them and use that to find chunks each time I need to modify them.
Class1:
