Sort An Array And Remove Duplicates?
Sep 8, 2009I have a semicolon delimited string (e.g. an EMail Address List returned from a database or a textbox). How do I separate the string into an array, sort, and remove duplicates? The code below works to separate the string and sort the results, but doesn't remove the duplicates. I could probably then loop through the array and copy to a new array to eliminate the duplicates, but there must be a better way to do this using the VB.Net Array, String, and Collections handling classes.
Dim s As
String =
"Test; Test8;Test1;Test2;Test3; Test8;Test4;Test5; Test6"

View 3 RepliesVB 2010 Express - Remove Or Add Several References
Jan 21, 2011I have taken my project that seemed to have several bugs in VB2008 Express and upgraded to 2010. I had to remove or add several references again. I don't have any more errors but I have the following 5 warnings that keep me from compiling the build. I was wondering if anyone could give me some suggestions on what these mean or how to take care of the problem. I will list the warnings below. I'm on a Win XP machine with Office 2010 (if that might affect things).

This last one I have gotten before but when I tried to update the components it only caused my program to become corrupt and tons of errors. I'm not sure if I did something wrong previously or if this might have been a random occurrence.
VS 2010 - Any Way To Remove Illegal XML Characters
Feb 15, 2012I am retrieving string values from a table and then encode each term to make a httpwebrequest to an api. It works fine and the terms allow for foreign characters like japanese/arabic/chinese etc and these are inserted fine. The problem occurs when some of these terms contain weird characters and that is when the request is bad. The only reason it is bad xml and the template I follow gets invalid are when these characters are present. I use the
system.securityelement.escape
And also
httputility.htmlencode
As part of my cleanup. One of the weird characters ends up appearing as a space but it is not since the trim(term) does not work and when I look at the xml in visual studio it looks like an ' &' with arrow pointing up attached to it. It does not appear after I pasted it here.It appears as a line feed or carriage return and I have tried to remove that too. Anyway is there some way I can ensure that these sort of characters are removed and if I were to use the binary values like <32 invalid, will foreign characters then get excluded.
temp = temp.replace(vbCr, "")
temp = temp.replace(vbLf, "")
temp = SecurityElement.Escape(temp)
VS 2010 - Cannot Remove Components With Uninstall
Jul 15, 2010I don't know what's got into them but they decided to purchase vs2010 pro licenses in my company. Anyway i gave it a quick look and since i don't need to have it installed right now (service pack 1 first, Microsoft anti-bug law) i uninstalled it. The problem i see is that it leaves leftovers everywhere.C++ redist, ado components, sql r2 components etc. These will not be deleted if i just remove vs2010 but will be installed if i install vs2010 full.Anyway i ended up removing them one by one and it took about 30-45 minutes. So has anyone have done a removal? Is this the case? I cannot remove most of the components with one big uninstall?
