So 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...

I 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.

I'm creating this program where the user inputs their name in this one textbox, and they click on the button where it should come up with their name in reverse(Last Name, First Name) in a message box. My message box doesn't work. My code does show I'm using the If statement because I'm trying my make sure the user is inputting letters only and nothing else. But I would fix that later thats not my biggest concerns.

I 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.

I was trying to figure out how to convert a string (that the user would input to the program via a textbox) into actual code for the program to compile. For example, if the user was to enter: (5*100)+(20-3). How could you take that inputted string, and have the program solve it and return the value?

What is the right way to use a custom format string on .e.g a zip code?The zip code in the database might have 9 characters, but the program should only output five. Using string.format("{0:#####}","322318825") will output "322318825", the entire 9-digit code.

i have found a few encrypt/decrypt tutorials online but either they dont work or they only work when the application is running so if i encrypt a string using some code i find and save it (in its encrypted form) and then restart the application and enter the saved encrypted string into a textbox and run the decrypt code it wont decrypt it. i don't understand why en/de-cryption is so hard or why there are so little working examples online. could someone be so kind and show me some code that can let me en/de-crypt a string even if i restart the application or use it on a different computer? and doesn't show the weak key errors all the time.

I am working on a function that returns an array of variable-length strings that have a certain starting and ending delimiter. The input to the function is a string. I am able to do this by using if-then statements with InStr(). I was wondering someone knew of a more elegant way. I tried using the split command but I am splitting on one delimiter so I don't really get the result. I could then parse from the results but I am back to the same boat with using InStr().
