I'm having problems while attaching some strings to some XML nodes.To explain this better I've made a simple example... just imagine that I have this XML code:
<song>
<title>
Surfin' USA
</title>
</song>
notice that instead of simply writing "Surfin' USA" I'm expressly using ' instead of the single quote character.The XML code is valid - or at least it has been considered valid by some tools I have found and tested online.My Problem is that when I try to put that string into a XmlText object, this way:Dim xmlDoc As New XmlDocument()

reading special characters within my VB code. ASCII code Char(34) = " works fine but Char(60) = < and Char(62) = > are not being read.

I'm trying to ensure that all characters which are not numeric, or alphabetic are converted to HTML code when submitted to my database.
[Code]...
This successfully converts anything to HTML, but now I need to put some condition in there so it only does it where I need it to. ie; on any character which will either screw up my database entry, or screw up formatting when returned back to the screen as HTML (this database content is for product data for a website).
So for simplicity, I guess I want to convert only charcters which are not A-Z alphabetic or 1-0 numeric.
I could use isNumeric, but not sure how to detect alphabetic characters.
I've been Googling and found something which looked like it would work, but the logic/filtering was wrong.
So I figured I'd ask here :D
So I have a program that parses a text file, and replaces keywords in it based on some criteria I've set up.I open the file, read it into a string, replace a line, then write that string back to a file.My problem is if the text file has any international characters in it, they get eaten when I rewrite the file.

View 1 RepliesI have an application where I'm allowing the user to edit the text of a treeview node. Is it possible to "lock" portions of the node's text to keep it from being edited?
For instance, if the text is "BK01" originally, can I keep the user from editing the "BK" prefix?
I currently validate the user's input when they are finished editing, but I'd like to keep them from entering incorrect information to begin with.
I have encrypted a string to something like this:
1. Asak2$)kla1015QAXKFskfa332aSJ2(Ska@Skljcmcel3p.lq,aowpqaskla2@)Skx.:Pdm^),dfs;
what i want to is convert this string to something like this

both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
I will then confirm the (2) from the client.
I want to create a VB.NET function that will take a string containing accented characters and convert it into the non-accented equivalent. My particular requirement is associated with non-English names. Some real examples are timac, Huki, Bttcher, Bj¸rnbakk, rnrohr and Synneg. I would want to convert those examples to Stimac, Hukic, Bottcher, Bjornbakk, Furnrohr and Synnevag, respectively.I am aware that a(with an umlaut accent) is often replaced by 'ue' but replacing it with u is better for my purposes. Similarly, I want to replace with o, rather than 'oe'. I am assuming that all the required conversions will need to be hard-coded in the function.Are there any slick ways to write such a function, ideally preserving the capitalisation in the original string?

I'm working on decoding a NMEA sentence that is a compressed 8-bit string. I'm having a very hard time of wrapping my head around the bit manipulation needed to convert this string. If someone could get me started with this it would be great.

How to add a child node to a specific node in treeview?
Say i have "Item1" in treeview already, How do i add "SubItem1" to "Item1" as it's child node?
I know its probably really simple, but i tried lots of stuff, i just cant get it working.
Basically, it refuses to find the node when the root node contains an attribute.

When I do xml.SelectNodes("DataSet") with the xmlns in the root tag, it finds no nodes. If I remove the xmlns attribute, it works fine.How can I make it work while leaving the attribute?
Finding the level of the particular xml using a node value in .Net Experts ! This is my sample Xml.This is a tree structure and T->T.1,T.2->T.2.2,TA->TA.1 - this is the tree strucutre. I know the value of tag . ie 1232,1343.. etc.Using this ID how can I find that 1343 is coming under 1232. or 1490 is under 1090 which is again under 1232.Expected output : if i pass 1490 then I need to know 1490,1090,1232 etc (from that nodeto the top node).I am using .net 2.0

Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

View 3 RepliesI need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
