Reversing A String And/or An Array
Oct 24, 2007So for an intro to programming class, we use visual basic, and i have to write a program that reverses the characters in a string. I've written a code that (i think) turns the string into an array, and then used the array.reverse method to reverse the characters.
I feel like my code is correct, but clearly it is not....when i run the program, there are no bugs, but instead of giving me any part of the input string, it returns "System.Char"
I'm a TOTAL beginner, and clearly not very good at this sort of thing, but here's my code for my "reverse" button:
CODE:
I'm open to other methods for reversing strings, but I'd like to stick with this one if at all possible...

VS 2008 Bitwise Operation (Reversing Bits)?
Feb 16, 2011I have written a simple VB.net application which saves information to an RFID tag. I am now trying to compress my data. The solution I have come up with involves bitwire operation.Basically I store 2 numbers per 1 byte (0-9, 10 being a period, 12 possibly being a negative/positive flag,13,14,15 unused as of yet).The code I am using basically shifts the byte containing a number left, 4 spaces, then 'OR's it against another number.Therefore 12 is now represented as 00010010. The problem i'm having is decompressing. Obviously getting the '1' back is easy, as I just shift right 4, then grab it. I need to append or remove the last 4 bits.My solution after many headaches was to reverse the bit order, shift left 4, then reverse, then tostring it.
View 17 RepliesReversing A TreeNodeCollection?
Apr 1, 2010I was wondering how it is possible to reverse a TreeNodeCollection. Since it doesn't have an inline reverse function, I've tried several other methods to no avail: everything from copying the nodes into an array (which has a built-in reverse function), reversing it, and then copying it back into the TreeNodeCollection to using a custom reversing algorithm. Nothing has succeeded.
[Code]...
Any ideas as to why, or how, additional nodes are being added? It doesn't make sense to me as to why that would happen. All I'm doing is changing the values of nodes that already currently exist.Edit: In addition to this method, another possible way to approach it would be to sort the treeview in reverse order in the first place (I think by using an ICollection, or possibly IComparer?), but I've no idea how to accomplish this. I'm not even sure where to start regarding using an ICollection to sort the nodes in a custom fashion.

VS 2008 : Match Words From One String To Another String?

VS 2008 A String Without A Value Was The Same As String
Jan 5, 2010I'm writing some information to an SQL database in my program and I am using parameters with the SqlCommand class, thinking that this would take care of things like this for me but unfortunately it has not.
What I am doing is this: I create an instance of a class which has several properties, one of these properties is a String and in some cases there is no value assigned to this property,I then write the value of these properties to an SQL table.
what I was expecting was that if the value of this string property had not been set and I tried to get the value of it then I would just get String.Empty but it is actually returning Nothing.then when the SqlCommand comes to try and pass this in as a parameter it throws an exception stating that an expected parameter is missing.
This is how the property is defined:[code...]
I have managed to work around this by changing it so that the backing field is set to String.Empty when the class is initialised but I've never had to do anything like this before as far as I recall, I just thought that any String that had not had a value set would be String.Empty rather than Nothing. Am I just going mad or does anyone else think this is odd?
If I do this for example, I do indeed see the messagebox alert:[code...]
Also, I dont have the same problem with properties in this class that are Integers - if they are not set then I just end up with a 0 being written to the SQL table, which is what I want the string property to do (just write an empty string to the database if the property has not been set).
I'm guessing that is because Integers and other Value types have a default value (is it ALL value types that have a default value or just some?), but I thought Strings were made to behave pretty much in the same way with String.
