Here is how I have done it:

private void treeView1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)

{

if(e.Button == MouseButtons.Right)

{

treeView1.SelectedNode = treeView1.GetNodeAt (e.X ,e.Y );

}

}

how to implement a link class?

I want to code a link class that links two objects of another class. In C++ I used two pointers as attributes. In C# even if I use unsafe code I have an error because the class is managed:

<br />
public class A<br />
{<br />
<br />
}<br />
<br />
public class link<br />
{<br />
private A *pA1;<br />
private A *pA2;<br />
public void create_link(A a1, A a2)<br />
{<br />
pA1 = &a1;<br />
pA2 = &a2;<br />
}<br />
}<br />
<br />

The error appears when I make the assigments: "pA1 = &a1;" and "pA2 = &a2;".
How I resolve this problem? Confused | :confused:

Thanks in advance,
Rodrigo Gil.

You simply need to do

public class link
{
   A a1;
   A a2;
   public void Createlink(A a1, A a2)
   {
       this.a1 = a1; this.a2 = a2;
   }
}

Remember, unlike C++, <code>a1</code> and <code>a2</code> are *references* to instances of A, not instances of A. They are sort of like C++ references (&).

Hi Earlier during win16 there was a dialog style DS_SYSMODAL through which it was possible to make systemwise modal dialogs or forms... but this api is now obsolate, and i think for good reasons.

It is absolutly not a good idea to restrict user to a single window.

Hi.
I have just completed my first add-in for outlook 2003-2007 and installed and tested it on my machine where it works as expected (creates a custom commandbar and adds a button to it which triggers an event).

When i right click my toolbar area i can see that my custom toolbar is checked and available. However when i install the application on other users computers the installation says everything went ok and it finishes, but when i open outlook on their computers its not there and neither is it available under the toolbar menu.

We are using XP Pro and my PC uses the Office 2007 beta 2 and theirs are Office 2002.
All machines have .NET 1.1 installed

Thanks in advance
Johan

Hello

You don't need to convert it to dll. You can read the output of the console in your C# application. See this post[^] on hot to do it. Don't forget to make the console hidden when it starts.

.Net framework 2.0 is must for the application builded upon it.

So, You have to install .net framework 2.0 on the every machine

to execute the application.

You should only need to install the .NET Framework 2.0 once on each machine. If you need to keep reinstalling it every time you run your application then there is something wrong with the machine.

It is recommended that Servers are kept patched and up-to-date. I wouldn't see it being a problem to state that your application requires Service Pack X in order to run.

Setting Treeview to another Treeview

I have a treeview and I want to set another treeview to that treeview

when I set TV1 = TV2 and do a breakpoint TV1 looks to have all the nodes, but it doesn't display. Does anyone know what I might have wrong.

Thanks.

Hello

TreeViews are reference types. That means that TV1 = TV2 will only copy the reference to the same object, but at the end they are still one thing. If you change anything in TV1, it will be also changed in TV2.

To copy the whole NodesCollection of one TreeView to another

TreeNode[] TV1Nodes = new TreeNode[TV1.Nodes.Count];
TV1.Nodes.CopyTo(TV1Nodes, 0);
foreach(TreeNode Tn in TV1Nodes)
    TV2.Nodes.Add(Tn);

Welcome to CodeProject! Big Grin | :-D

There is a very fine articles section here in CodeProject, with many articles for beginners. If you are stuck with something that you can't find in the articles -search first of course-, or google, you can always come here and ask.

Sure they are different languages despite the similarities. IMO C# is by far superior to VB, with all respect to all VB programmers and fans. Yet if you know VB, getting along with C# may not be that difficult. You just need to do you best.
