i have a vb 6 activex dll and i am able to run a form inside of the dll is it possible to do the same thing in csharp ( run a form from a dll) or is there no UI in csharps DLLs?
Thanks,
Chad Aiena

You can just wrap up your form inside the DLL. As the form is just another class, you can pretty much do what you want with it (well, within reason).

can you give me a quick code snip of how i would put it in the dll (sorry i am still learning csharp)
or something like this but how to i show it
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
namespace dllform
{
public class Class1
{
Form test = new Form()
}
}
Thanks,
Chad Aiena

I'll tell you how to do one for yourself. Start off by developing a form in the designer as an executable. You can then change the application type to DLL in the project properties. Compile it up and you have a form inside a DLL.
Next, create a new project and reference the DLL. Then, in your code you just need to call the form. To do this (assuming your form is called MyDllForm in the namespace MyNamespace):
MyNamespace.MyDllForm form = new MyNamespace.MyDllForm();
form.Show();
I hope that helps.

I'm using the VS 2005 control System.Windows.Forms.WebBrowser. I want to be able to track button clicks. If I've navigated from a page with multiple buttons, how can I tell which button was clicked?

Hi I've an application in which I use tiff images (scanned ) through Microsoft Office Document Imaging and save them,while closing the application invaribly I get error that "Application referenced memory which is invalid Click on Ok to terminate the application"
Which is usual in windows. I'm disposing all the objects I think before closing so what more could be done to remove it? Or Whats the cause for this and what could prevent it?
Thanks in advance.

Hi!
I use VS 2005, and C#. If framework 1 and framework 2 installed, in a project I use only .net 1 compatible thinks, but when I compile the executable, and transfer it to a machine witch haven't got .net 2, gon erro message.
How can I adjust my project to require only .net 1?
Thanks for help.

Unfortunately for you, VS 2005 targets .NET 2 only. In other words, you can't develop .NET 1 applications with it. What you could do is to create an installer for your application which installs the .NET Framework 2 Redistributable on the client.

Really ?
I thought that by changing some setting (I would guess inside AssemblyInfo.cs or maybe
in a manifest file)
one could tell .NET that the preferred version would be 2.0 but if that was not available
.NET 1.1 (or 1.0) could be used instead.
Of course as soon as some 2.0 specific feature would get accessed, it would throw when
running on 1.x
I dont know the details but would like to know more about it...

There is a way of doing it, but it means that you have to compile up outside of Visual Studio. VS2005 uses the .NET 2 compiler.
Providing that you haven't used any of the .NET2 features such as partial classes etc..., then you can actually compile the application from the command line using the .NET 1.1 csc.exe compiler. It's not neat, but it does work.

I hate to swear in a forum where most people use Visual Studio but here goes...
How about SharpDevelop? It can target either .net 1.1, .net 2.0, Boo and Mono.
It can also import projects from Visual Studio.
It doesn't claim to be a replacement for VS but maybe it's worth a try.

Why do get get a new form each time I create a new instance?
public class Form1
{
...
method to handle 'next' button to next graph
graphnumber++;
switch (graphnumber)
case 1: dg1 = new DrawGraph1();
dg1.Draw();
break;
case 2: dg2 = new DrawGraph2();
dg2.Draw();
break;
etcetera
...
}
public class DrawGraph : Form1
{
//abstract method Draw();
public class DrawGraph1 : DrawGraph
{
//override method Draw();
public class DrawGraph2 : DrawGraph
{
//override method Draw();
etcetera
This is probably so basic that books about C# won't even mention it, still I find this a significant problem!

Your new instance of DrawGraph1 or DrawGraph2 is a Form1 (which I expect is a Form). What else would you expect to happen when you instantiate a DrawGraph1 or DrawGraph2?

My problem here was that I couldn't get my subclasses to work if I didn't put a ': Form' behind the class DrawGraph :
So when my DrawGraph class doesn't inherit from Form1 that then there wouldn't be a new window opened at each new instance of DrawGraph?

Hello!
Again I am getting the error message "member names cannot be the same as their enclosing type"
I have a class Matrix which is public. And I am wondering if C# lets a class like Project return a Matrix as it is instanced.
Last time I had this problem it had to do with certain variables not being public. But in this example there are so few variables that I figure I got all my bases covered.
What did I overlook or forget to consider?
Ranger...
public class Project
{
//  Project: member names cannot be the same as their enclosing type
public Matrix Project(double Rx, double Ry, double distance)
{
return new Matrix
(
Math.Cos(Ry),
0.0,
Math.Sin(Ry),
0.0,
Math.Sin(Ry) * Math.Cos(Rx),
Math.Cos(Rx),
-Math.Cos(Rx) * Math.Sin(Rx),
0.0,
0.0,
0.0,
0.0,
0.0,
(Math.Sin(Ry) * Math.Cos(Rx)) / distance,
-Math.Sin(Rx) / distance,
-(Math.Cos(Ry) * Math.Cos(Rx)) / distance,
1.0
);
}

I think it's complaining that the Project class can't have a property or method called Project.

I know, but why? I mean to create a new instance of a class you make a method with the same name as the class right? This should work...
Ranger...
As it is this code source went from about 1.75 page to almost 4 pages and this was the only error I got. It is my inexperience that I don't know why this is.

Correct. That method (the constructor) is never specified with a return type. You're attempting to define a constructor for Project that returns a Matrix.
I recommend renaming the method to CreateMatrix() or something similar.

I thought that could be the reason.
Thanks, I will try that!

After moving this method from its own class to the Matrix class, I then made a second Matrix instance method which uses as input the arguments of the former 'CreateMatrix' method, and this works too! I find it nice to have only one method to call for new and with its own arguments.
I find C# very interesting. And I am thanking you Ravi for your assistance.
