you do just like in c++(note that unlike c++ there is no shortway of constructors)

Code:

---

MyClass myClass = new MyClass();
myClass.MyMethod();

---

---

I did that, since I know C++ that is what I did first but it doesn't seem to know what the hell my class is as it says it's undelcared.

Bah, I'll figure it out

show the code

Did you reference it in your proj ?:rolleyes:

That is in the DLL (source omnitted of course, it shouldn't be needed) then I have the DLL referenced to my Forms Application. I tried to create the class within the Forms Applications and with the DLL as well (in C++ I can do this at the end of my declarations so I assumed the same in C#) and I just get the error I said before.

Code:

---

IO a = new IO();

Of course

Try:

Code:

---

Controller.IO a = new Controller.IO();

---

or simply in the upper part of the code:

Code:

---

using Controller;

---

I forgot to mention I did this too, it doesn't see to acknowledge my namespace because I get no inteilisense

EDIT: Damn your Ninja Edit, me trys the 2nd one

errm what does the error say?

It says the class is undeclared.

I am using my C# class in my VB program (incase you missed that) and I cannot use 'using' after any namespace elements so I cannot do that within my DLL.

hmmm I didn't quite get what you mean..in vb.net instead of using 'using' you use 'Imports'

I know that but it isn't needed and wouldn't work with it anyway.

using cannot be used in C# after the namespace's elements.

ah yes , that was what i did try to mean when i said

anyways as a side note you can use 'using' when working with any object that supports IDispose:

Code:

---

using (IDispose obj) {
...
}

---

and in the end it will call the Dispose() method alone

OK , Listen , on the View Menu , can you see your dll structure (namesapce , then class , then methods ) ??

Yes I can click on the class view and it shows the hierarchy of my DLLs (namespace->class->functions)

Are they public static or what modifiers are they marked with ?

Remember , if they are static , then you should call them directly as if they were member method of the same class you are working with .

they seem to be instances

public, I posted the code above, I just removed the syntax from the 2 functions

This thread turned into rubbish . I got confused . :confused: Can you send this damn dll for more investigation in our lab ? :)

I posted the DLL. The only difference between that code I posted the code entire amount of code the DLL is using is the fact that I removed the syntax from within the functions.

and yeah, this thread changed, lol

Umm ,

VB Code:

Imports Microsoft.CSharp

:rolleyes:

Nope, I get a "declaration expected" error when I try to create the class.

Ugh

After you got it referenced , try closing your application and run again . Uh , hope I'm not saying bull**** but surely this makes one crazy .:confused: . I mean everything seems to be fine as you mentioned but oh well .

I reloaded VS 2003 and it still does it, ugh.

I don't get it, in the class browser it shows the Controller namespace and under that it shows my class and then my functions, but yet I cannot use any of them! Ugh.

There is probably something really simple you need to do and I just overlooked it or something.

There is something that you must be missing. Did the DLL compile fine? Where does UCase come from? Here is an example like the code you posted and it works just fine.

I never tried to compile it. There is no reason to, right now I have 3 projects in my solutions. 1 being the VB DLL and the other being the C# DLL. I am trying to port the VB DLL to the C# DLL before I delete the VB DLL project, so I haven't tried compiling it yet. I can't even use the code from the C# project anyway so there isn't much since to t and compile it anyway.

I'll check out your solution though, maybe I just missed something stupid and I'll figure it out

BTW, UCase() is a VB function. It makes a string uppercase.,

Okay, I think I got you guys confused. I want to use this C# DLL in a VB.NET Forms Application. Edneeis' example is of 2 C# projects, and it works fine, and I am doing the EXACT samething except I am using a C# DLL and a VB.NET project.

Is their something special I have to do since the DLL is in C# and the app is in VB? I didn't think you would because of the CRL (I think I got that one right).

Use release mode and build your dll . Well , you must do this sooner or later . Try this dll in new project and see what's going to happen ?

No its got to be something else here is an example with a VB exe. So if you haven't compiled the dll then I'm assuming you set the reference to the DLL Project right (via the Project tab since there is no actual DLL yet)?

Hmm very strange. There isn't anything you have to do different since it comes from a C# dll.

Yeah I referenced it. I tried building it and holy crap are their alot of errors.

Ack, lol.

Well quick question (again). Is their a C# equivelant for UCase() and Replace()? Those work fine in VB and I tried using Microsoft.VisualBasic but that wouldn't let me use them.

Then fix the errors , they might be your problem .

Yes, ToUpper in string objects .

Code:

---

string s="ABCD";
s.ToUpper();


string s2="Blah";
string tmp=s2.Replace("Blah","New string");

---

Okay it works now, lol

Now, PT, did you get what you needed? lol

hmm still not, and looking for the highlight code in #develop is a pain in the ass as it is too big and there is no place where it says where each thing is

If speed is an issue then I'd recommend not checking on every keypress. Just check if the last press was a space or enter so you know its at the end of a word.

And to go along with that, only check the last word or words that were typed. You shouldn't need to recheck the whole document everytime. There is a lot of optimizations you can do to this, but you will have to work at it.

Or start it in separate thread . I've read an article some time ago about MS Word in relation to threadings. It's multithreaded app in sense of one thread for checking grammer , and one for word processing, while some other do kinds of alignments at the same time . So , you should consider this as a solution .

Here is a small example using RegularExpressions. It uses the only check on spaces and enters as well as only checking the last word.

But the code i shown earlier in the topic only searched for the last word lol

edit: tried your code with the document i've tried mine code and it is even slower

The thing to understand is that my document has about 30k lines

Can you upload a file to use as an example? A lot of the optimizations mentioned are more for as you type. If you already have the file and just need to colorize it then I'm sure there are much better ways of handling the initial coloring.

question

Are we interested in finding speedy code for syntax-highlight existing files when they open, or highlight as a user types?
