    Vis. C# Expr. - Get all Form Names

    I would like to get all form names available - not just open ones.

    I've seen a number of snippets to do this, and they use Assembly, but Vis. Expr. will not let me do it.

    Here is an example I found:

    Code:
     //Assembly[] array = AppDomain.CurrentDomain.GetAssemblies();
    
                //foreach (Assembly a in array)
                //{
    
                //    this.treeView1.Nodes.Add(a.GetName().Name, a.GetName().Name);
    
                //    Type[] types = a.GetTypes();
    
                //    foreach (Type t in types)
                //    {
    
                //        if (t.IsPublic && t.BaseType == typeof(Form))
    
                //            this.treeView1.Nodes[a.GetName().Name].Nodes.Add(t.FullName);
    
                //    }
    
                //}
    
                //treeView1.ExpandAll();
    Vis. C# Express will not even let me do the first line: Assembly[] array = AppDomain.CurrentDomain.GetAssemblies()

    It doesn't have Assembly[] available.


    Thanks in advance.

    Moved to C#

    Welcome to the board, but can you please be a little more careful under which board you post?

    Thanks...

    Assembly is located in System.Reflection so either you state
    using System.Reflection;
    at the top of the cs file or you declare the Assembly object as such:
    System.Reflection.Assembly[] assemblies;

    As a follow-up, I'd like to have the form opened when user selects it in the tree. How would I do this? I can get the name stored in the tree node value. But I do not know how to use the value.

    Thanks.

    This is how i managed to open a second form, not sure if its the correct way though since i havent dealt much with reflection.
    Code:
    Assembly[] assemblies = AppDomain.CurrentDomain.GetAssemblies();
    Form f = null;
    foreach (Assembly a in assemblies)
    {
        Type[] types = a.GetTypes();
        foreach (Type t in types)
        {
            if (t.IsPublic && t.BaseType == typeof(Form))
            {
                if (t.FullName.Contains("Form1"))
                {
                    f = (Form)a.CreateInstance(t.FullName);
                }
            }
        }
    }
    
    if (f != null)
        f.Show();
    You might want to explore the Tag property so you can assign a certain Assembly to a certain node and so on. This should make the code something along the lines of
    Code:
    Form f = (SelectedNode.Tag as Assembly).CreateInstance(SelectedNode.Text) as Form;

    Yes! Very minor modification to change "Form1" to treeview1.SelectedNode.Text and to add f.TopMost=true.

    Works like a champ!

    Thanks, again!

    Last question on this topic: Is there a way to run debug on the present form, as opposed to having it start at the root? It would be nice to program a form and check it out without having to go through a bunch of hassle.

    You mean switch from normal run to debug mode in the program? As far as I know this is not possible but this is really outside my knowledge.

    No. I mean to just debug the current form in the design view. Let's say I have six forms open. I am working on one of them. I want to just test that one instead of having to use the tree we made to get to it and open it.

    I plan on having many forms in the project. The tree will become large, and I will get tired of having to scroll to find the form I want to test.

    So just add code to the main form so that the form you are working on is opened automatically when you start the program?

    I could do that. Was just hoping for something easier since will be dealing with lots of forms. Anyway, your help above was what I really needed most. Thanks so much. Have a great day!
