Hello,

I'm a VB.NET developer normally, so I created a DLL with the functions I need. Now I have to load the DLL into an Messenger Plus! Script, and after hours of searching, I can't find an example.
Is there anyone that could help me out with this?

Kind regards,
Thomas

I'm fairly certain it's the same as calling DLLs for APIs so you want to look for Interop.Call(dll_name, function_name, param1, param2 etc)

nope, not for .NET dlls. there isn't an easy way to do it.

Well, in that case, I have another question:
I have a string "* - Microsoft Visual Basic 2008 Express Edition", and the only thing I want to be left over is everything before " - Microsoft Visual Basic 2008 Express Edition".

So, "Start Page - Microsoft Visual Basic 2008 Express Edition" » "Start Page".

How can I do this with JScript RegExp?

You could do it the dirty way, by using string functions such as String.indexOf and String.substr:

code:

---

//This is a sample string, you'll probably want to get this string through some code...
var strTitle = "Start Page - Microsoft Visual Basic 2008 Express Edition";
//Try to find the last occurrence of the title suffix
var pos = strTitle.lastIndexOf(" - Microsoft Visual Basic 2008 Express Edition");
if(pos !== -1) {
   //Found it, now cut the wanted part from the string
   var strTitleName = str.substr(0, pos);
} else {
   //Not found, some error handling here?
}

---

A bit more advanced method, but much shorter and cleaner, is to use regular expressions:

code:

---

var strTitle = "Start Page - Microsoft Visual Basic 2008 Express Edition";
//Make a RegExp object - check out the link for an explanation of the used special characters.
var reSuffix = new RegExp("^(.+) \\- Microsoft Visual Basic 2008 Express Edition$", "i");
//Test the string with the RegExp
if(reSuffix.test(strTitle)) {
   //Got a match, the name is now in $1
   var strTitleName = RegExp.$1;
} else {
   //No match, some error handling here?
}

---

It doesn't seem to work, when I use it in my program nothing happens.
When I use this website
http://www.regular-expressions.info/javascriptexample.html and use "^(.+) \\- Microsoft Visual Basic 2008 Express Edition$" as regexp and "Start Page - Microsoft Visual Basic 2008 Express Edition" as subject string, the message is "No match".

Ah, after some messing with RegExp, I see that you had a slash to much, it has to be "^(.+)\ - Microsoft Visual Basic 2008 Express Edition$" Thankyou!

Ah yes, my mistake. Hyphens should only be escaped when in a character class (between [ and ]).

Good you figured it out yourself!
