I'm currently stuck on something I need to have done for my application. I have a listbox where I have a lot of urls in the following format: [URL] With the quotes on it. Now I want only these links to remain in the listbox and to remove the quotes and rl around it. I tried using regex but it didn't worked out for me.
View 4 RepliesI 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)

What i need is, if a item in a listbox Doesn't exist, it needs to remove it from the other.
In the pic i have attached. Basically If it doesn't exist in Listbox2 then it needs to be removed from Listbox1 and tell the user which one has been removed.
i.e Test 02 doesn't exist. So messagebox would show "test02 has been removed" then remove it from listbox 1
It probably something simple thats sitting in the back of my mind, but for the life of me can't figure it out lol
