I'm reading in a binary format. Strings are in a string block at the end of the file.
In the format, each record has an integer that is the offset in the string block where the string is located.
I could use the BinaryReader.BaseStream.Position property to advance to the location of the string and read it, and then set the position back, but that seems like that would be messy to me.
I was wondering, is their any way to change a string into a line of math code. I was working on a graphing calculator project and am having trouble splicing up everything into variables and coefficient and operators. Example, having this block of code work

I have a button (btnAdd) that adds the content of a textbox (txtName) to a textblock (lblName). I want to add a date to the textblock when btnAdd is pressed but I want it to be a different font size and colour. So far my code looks like
lblName.Text = txtName.Text " " + DateTime.Now
I only want DateTime.Now to be a different size and colour. Is this possible? Instead of a label I need to display it in a listBox. My new code:
listBox1.Items.Add(txtName.Text " " + DateTime.Now)
i'm trying to removing javascript block from a string the contain website page.so if the page is something like that:

i want to remove the bolded part othe page.
This is an example of the text I want to modify:
0110
0001
0001
1000
[Code]....
Here, I want to replace two-line digits in bold(0110 0001) with a different sequence as the program scans the text line by line. But two things complicate the task:
1. the comma lines should be ignored, but
2. they also should stay intact after changing the digits.
Is there a more elegant way to structure the following code, which takes a comma delimited string containing certain values in specific positions and assigns the values to the properties of an object?[code]...

First of all: is it a problem that I have that Try/Catch/Finally block inside of a SyncLock?
Second of all: suppose this code runs, on an event, potentially many times within a small timeframe--say, ten times in one second. Is it OK to have it SyncLock like this, or would it make more sense to have it add a line to a Queue, and then write all the lines from the Queue to the file on a timer that goes off, say, every second?
I have a block of HTML which I want to write to a file. It contains about 30 lines and it's difficult to escape all the double-quotes in individual WriteLine statements. In PERL, I can do something like the following to write inline HTML and print everything upto <<OUTFILE to outfile as-is, is that possible in VB .Net 2008?
print <OUTFILE

Okay Now I only get two errors (I dont know how to solve them)
Error3Class 'BaseApp' must implement 'Sub OnCompilerError(errors() As CompilerError)' for interface 'IScriptManagerCallback'.
And
Error4Class 'ScriptManager' must implement 'Sub CompileAndExecuteFile(file As String, args() As String, callback As IScriptManagerCallback)' for interface 'IScriptManager'.
But What I would also Like to know (as well as how to fix the errors), is would the code work?

For some reason I cannot get the %%LINK%% and %%NAME%% Replace() calls to work properly. I checked to see if it was encoding-related, so I made each file UTF-8. And also used the forced encoding overload of ReadAllText(String, Encoding) and still no dice.
trying to find a decent answer for my question; I do have a utf8 file which I (down)load, manipulate and wanting to save back again.The result always is that the file I produce is not in utf8 format;
