Whoops, sorry about that - my apps engine is in C# and the GUI is in VB (don't ask) and I tend to spend more time on the C# messageboard - I guess I got bit carried away D'Oh! | :doh:

hi, I need a regular expression to replace / with // in a richTextBox1. how is this done? I have this:
string replace_1 = Regex.Replace(richTextBox1.Text, @"/", @"//");
but it doesn't replace the string with the replacement string in the richTextBox1. can you show me something that would work? thanks in advance,
Stephen

Why do you need a regex here ? The string class is well able to do this for you.

can you show me what the code would look like. I tried this:

<br />
string replace_1 = richTextBox1.Text;<br />
replace_1.Replace("/", "//");<br />
richTextBox1.Text = "";<br />
richTextBox1.Text = replace_1;<br />

but no luck.

Have you looked in the debugger ? I think the rich text box is your problem.

RichTextBox1.Text.Replace(@"/", @"//");

You're going to run into a problem each time you run this though. Every time you run this, or any other similar function, you'll end up doubling the number of slash marks EVERY time it's run. So...

/ This is a test...

will become

// This is a test...

will become

//// This is a test...

will become

//////// This is a test...

Unless you put in some code that checks for this condition...

I'm having horrible luck with this. i made a simple simple app with one regular textBox1, and a button. on the button's click I have this code:

textBox1.Text.Replace(@"/", @"//");

just like you showed me. it still won't work (I also tried it with the richTextBox, and still no luck. I'm so annoyed at this. It's plagueing me. any ideas? thanks

Try this

str="aa/aaa/aaa/"
str1=""
Iterate each character in str
{
	if TheCharacter =="/" 
	  str1+="/"
        str1+=TheCharacter
}

<italic>Work hard, Work effectively and a bit of luck is the key to success.

Hi!
It's quite simple, strange that no-one noticed so far.
string.Replace(a,b) returns a new string holding the text after the replacement.

So if you simply write:

richTextBox1.Text = richTextBox1.Text.Replace("/","//");

you should be fine.

Based on some examples, I've successfully managed to retrieve the 32x32 version of a file icon by passing 0x0 into the uint uFlags parameter of SHGetFileInfo; however, I am unable to figure out how to retrieve the 48x48 version.

Let me know if there are any examples out there on this or if you have any suggestions.

Thanks!

Absolutely perfect! Well, I can throw away the code I had because this is exactly what I need. Although, I’m glad I struggled my way to get to this point as I picked up some really great experience along the way.

Anyways, thanks for your help. I owe you one!

Hi all,

I need some help to create technical indicator for the project. I have to read the file in csv and create same file after reading and calculating the values and some more with indicator and model. I need some little help for creating technical inidcator like SoctchRSI, RSI, EMA, MACD.

Thanks in advance.

I can't make heads or tails out of your question, but I reckon the easiest way to read a CSV is to read a line at a time, then to do a split on the ,. If you can break your request into plain English, I'd be happy to try and help some more.
