You should show us the code that actually (attempts to) load the DLLs.

thanks for the post, it did help a portion.

I ran into a new problem. My Assembly class also implements an interface. When I try to cast the object to the type of the interface, i get this exception:

The type 'ProjectA.PageBaseOperations' exists in both '{9491320D-D340-4DBD-9D31-99B6FDD80C76}' and '{0EDD5000-CA92-4762-A84D-5F68E055ECCE}'

Hope the Article by Giorgi Dalakishvili Here[^] will help you.

And also the article by Kareem Ali Saving from a Stream to a file[^].

Hope this both article will help you and i think if you create the Stream as an exe file means you can run it otherwise you cannot.

Hi everyon. Smile | :)

I have a Library project that is gonna' become a dll file that is gonna' be used as a plugin for another windows forms project.
I have written the interfaces and other things to do the plugin managment and other things but now I am gonna' write the plugin and the plugin is gonna' do a time-critical job and the question here is that:

Is the thread that plugin is gonna' use the same as main program?

If the answer is yes:

How to invoke a method from a recently started thread to the main thread in a simple class(not a form or control or a component class)?

Thanx for your help. Rose | [Rose]

Sojaner!

The code runs in the thread that called it. If the UI thread called the code, then it runs in the UI thread. If it's called by a child thread, then it runs in the child thread.

It is not possible, because may be the entry point of new dll file is not the same as older one!

Sending an email with a picture inside and saving an open doc

Hi everybody

I have a Word file with a picture inside which I saved as HTML filtered. I'm trying to send the Word file and have a little difficulty with it.
I know how to send a regular file but now I want to add to the email a picture which will be seen in the email and not as an attachment.
I know that I should use the "AlternateView" class and "LinkedResources" as the image but I don't know how to combine them together with the Word file itself.

Anybody did something like that or can direct me to a simple sample?

Another question: Is it possible to save a Word file that was opened for the first time and not saved as HTML filtered programmaticlly?

Thanks for any help Smile | :)

Can´t Create Unit Tests

Hi,

I'm developing with Microsoft Visual Studio 2005 Version 8.
I want to create unit tests but can´t do so.
I don't have the new test option in the solution explorer.
Also, I can't add it as a project.

Don't know why, I have done it in other installations.

Do you know how can I add the possibility to create unit tests in C# in Visual Studio 2005?
Do I require the team edition?

Thanks

Martín

You require Team Developer, Team Tester or Team Suite edition.

For the integrated stuff from Microsoft, yep. Team Edition is the only one with Unittesting integrated.

You might want to look into NUnit[^] as a free alternative.

Absolutely, it works just fine.

And for simple cases, you can also implement a much simplified test harness yourself,
inside your app (so it searches for TestFixtures and executes them one by one).

I'm using csUnit, which features a nifty VS2005 plugin, but is otherwise the same as nUnit. You can find it here.

Standards are great! Everybody should have one!

The good news is that Visual Studio 2008 Pro will have unit tests. However, at the present time it seems that the open source unit test tools (possibly augmented by add-ins) are generally better than what is currently supplied with VS 2005.

thank the one help me!

Hi Lockepeak,

What do you mean with ' click once ' and click ' twice.

Do you mean single click and double click, because in that case you can easily do :

this.button.Click += new System.EventHandler(this.method1);<br />
this.button.DoubleClick + new System.EventHandler(this.method2);

If you mean click once, and then add 1 to i , you could do :

private void method1(object sender, EventArgs e)<br />
 {<br />
  i=(i+1);<br />
 }

assuming that you int i referenced in your application.

well, I'm not sure what you're doing wrong but I just made a test project and it works perfect. Every single time I click the button , 1 is added to int i. What I think the problem is , is that you don't have the integer referenced properly in your application. You have to reference it throughout the entire form so that it remembers the previous value:

namespace Blah<br />
{<br />
   public partial class Form1 : Form<br />
    {<br />
        int i = 0;<br />
        public Form1()<br />
        {<br />
            InitializeComponent();<br />
        }<br />
        <br />
        private void button3_Click(object sender, EventArgs e)<br />
        {<br />
            i = (i + 1);<br />
            MessageBox.Show(i.ToString());<br />
            lbl.Text = i.ToString();  // optional<br />
        }<br />
<br />
     }<br />
   }<br />
}

if you reference int i anywhere else in the project, it will reset the value as soon as you dispose the messagebox. Intead of the messagebox, you could use a label to see the number increase everytime you click the button.

Hope this helped.
