Hi guys
How can I delete all occurrences of the word 'test' from a string
I.e. String Before: This is a test to delete all occurrences of the word test
String After: This is a to delete all occurrences of the word
Please give me some guidelines here.
Thanks

You can use split, like this:
string myString = "this is a test waffle";
string temp[] = myString.Split("test ");
myString = "";
foreach(string str in temp) {
myString += str;
}
Then, after all that, your string should be "this is a waffle".

what you could do is keep it simple 
use string.Replace.
ex:
string x = "This is a test,test";
string y = x.Replace("test","");
Console.WriteLine(y);
output should look like "This is a , "
have fun

Damn, string.Replace. How could i forget that. Oh well, time to go methinks.
On a side note, i appear to have found a new forum to live on for a while. Who would have thought it'd be here?

But what if you were to remove a word like '{test}' including the braces?

Nevermind I got it now, I'm just being stupid today...
Thanks again guys!

Is there a neater more professional way to re-write the code below?
<br />
public string StripString(string statementString)<br />
{<br />
string alteredStatement = string.Empty;<br />
<br />
string keyword1 = "[dbo].";<br />
string keyword2 = "[";<br />
string keyword3 = "]";<br />
string remover = "";<br />
<br />
string tmpStr1 = statementString.Replace(keyword1, remover);<br />
string tmpStr2 = tmpStr1.Replace(keyword2, remover);<br />
<br />
alteredStatement = tmpStr2.Replace(keyword3, remover);<br />
<br />
return alteredStatement;<br />
}<br />

Do you mean something like this?
Regex.Replace(statementString, @"\[|dbo].|\]", "");
instead of the function

I was thinking of Regex but wasn't sure.
Thanks for that Kain!

I'm not sure why you're removing the brackets and 'dbo' from SQL. It could open you up to syntax errors, especially since you don't account for the context whatsoever in these sort of find/replace methods. Plus, I remember reading somewhere that stating 'dbo' will improve lookup performance 
But whatever...just throwing that out there as a word of caution.

This one is more concise and more efficient since it doesn't create unnecessary temporary string instances.
public string StripString(string statementString)
{
string[] keywords = { "[dbo].", "[", "]" };
StringBuilder result = new StringBuilder(statementString);
foreach (string keyword in keywords) result.Replace(keyword, string.Empty);
return result.ToString();
}

string s = "this is a test";
s.Replace("test", "");

Hi, all replies may lead to damaged sentences such as "Nuclear s damaged the conants inines",
and basically ignore the subject line.

Actually, i think a couple of the replies inlcuded a space after the word test, so "test ". That would only ruin words ending in test.
And besides, if you do it the way i said originally (though of course, i had forgotten about string.replace) you can remove " test "
with spaces either side. And then when you re-build the string, add the spaces back in.

Words are not necessarily surrounded by spaces, there could be punctuation marks too.
This contest holds two "test" words for you to test.

Yar, stupid punctuation, ruined the english language. 
I concede to your brilliance.

Hi:
I am looking for a way to assure that only one instance of a WinForm application can be run on a local area network, how should I go about this?
I'm not up to speed with Sockets or UDP communications, so don't really know where to start.

i think the easyest way is to create a dummy file somewhere on the network (accessable to everybody)
when your app starts.
and delete when app closes.
in startup of your app, check for existens of that file (File.Exists)
Hope this helps

Although of course, evil people could find an delete the file, then run the form when theyre not supposed to! 
Depends on your circumstances though. This is definitely a good idea though.

Hmm. I found this topic: http://www.thescripts.com/forum/thread253568.html[^]
Doesn't give much info, but from what i can see you can get remote processes by using:
Process.GetProcesses("remote pc name");
and that you need to have remote access enabled on the rmeote machine, and maybe some other stuff. You might not need to use sockets at all, although they are rather quite simple to use.
So, you'd have to check the processes of each machine individually, and then run your form if you don't find an instance of your form anywhere.

Hmm, I was thinking more along the lines of a Broadcast or Multicast message and reply workaround.
The created file solution might be a quick & dirty solution though...

Make sure you (a) create the file if it doesn't already exist and (b) keep it open for exclusive access as long as the app is running.

Good Morning All,
First off, this forum has helped me a great deal with my endeavors of understanding C# better. I utilize the archives and searches extensively and have more times than not found the answer I needed right away.
This time however, I need some help directly. I am creating an application where by I am writing a config file in XML (thanks to a posting here), and one of the elements I need is a directory. I have found and am utilizing the OpenFileDialogue but this Dialogue Box will not allow me to select a directory only. Is there another object that will allow the user to select a directory.
I don't want the user to type in the directory, as you can imagine, just using the Dialogue Box would aleviate users anticipations.
Any help would be greatly appreciated.

There is another object that does exactly that: FolderBrowserDialog
Hooray!
