[RESOLVED] Check if the Form is running or not

[vincentg]

Guys,

Do you know a way to check if a specific form is running? Just like similar to VS 6.0 Forms Collection.

The forms are not a MDI Child at all and this is Windows application only.

Thank you. Prefered coding in C# but VB.Net is ok also.

Why not try a message box or a log - jennifer

Try something like

private void button1_Click(object sender, System.EventArgs e) 
{ 
Form form2; 

if(m_arrFormList.Count > 0) 
{ 
form2 = (Form)m_arrFormList[0]; 

if(!form2.IsDisposed) 
{ 
if(form2.WindowState == FormWindowState.Minimized) 
form2.WindowState = FormWindowState.Normal; 
form2.Activate(); 
return; 
} 
else 
m_arrFormList.RemoveAt(0); 
} 

form2 = new Form2(); 
m_arrFormList.Add(form2); 
form2.Show(); 
}

Array?... i was looking to a similar Forms property also like that w/c is
Form.OwnedForms Property but

I dont know if this is the best solution...
And if there is a Variable Object Collection w/c i will loop though it and see if a certain Form reference is running or not....

Well if you want your own forms collection you could make one, just add a form to it whenever you load it.

.Net has no equivalent to Forms Collection.

Yes, now refer back to my post #5 ...

I know and I read it already up to the
Walkthrough: Creating Your Own Collection Class

http://msdn.microsoft.com/library/de...ctionClass.asp

Just thinking w/c is better.
Your familiar with OwnedForms?
I dont know if this is a good one also.

Do you have C# 2005? If so you could use a generic List to contain your forms.

using System.Windows.Forms;
using System.Collections.Generic;

// ....
public List<Form> Forms;

[vincentg]

not installed yet.. but vs C# 2003, i had it here..
using System.Collections.Generic; <--- is this a lot better?

Planning to do the collection class w/c every time run a form i will just add it there and put something in the close event of the form to remove it.

[vincentg]

anyways, thanks for the feed back guys!

Pre-2005 you needed to write your own Collection classes if you wanted to use strong binding, in VS 2005 you can use the classes in the Generic namespace. Generic-typed classes are strongly-bound at compile time to the type you specify. So it's equal to writing your own Forms collection class, without you having to do all the work
