View 4 RepliesAssigning The Value Of A Label To A Variable Byref?
Sep 8, 2010I would like a label to always show the current value of a boolean. This will change a lot of times and would like the label to ALWAYS reflect this.
Is there some kind of way to have the label set to the boolean byref (so its always the same). Currently I'm assigning the label.text = boolean onLoad, so if the boolean changes after that its not reflected.

Pass An Object Variable But Doesn't VB Force Decalre The Header As ByRef?
Oct 20, 2011Why if you pass an object as byVal into a method is it then treated as if it were byRef? I know you're only passing the reference across when you pass an object variable but why doesn't VB force you to decalre the header as byRef?

Store The Location As A Variable?
Nov 7, 2009I 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.

.net - Store Data In One Variable Or Multiple?
Jan 30, 2010I 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.
