You should try to clarify your question.Do these forms belong only to single or multiple instances of your application?Are they windows explorer or another app windows?

Dim myAssembly As System.Reflection.Assembly = System.Reflection.Assembly.GetExecutingAssembly()
Dim types As Type() = myAssembly.GetTypes()
Dim mytype As Type
For Each myType In types
If mytype.BaseType.FullName = "System.Windows.Forms.Form" Then
MessageBox.Show(mytype.Name)
If (mytype.Name = "Backup") Then
MessageBox.Show("This is for u ")
Exit For
End If
End If

Hi,

There are property named "Name" which retrieves the form name that you should compare to identify a form.

Please let me know if you could get this done.

if your forms are opened then try this

MessageBox.Show(Application.OpenForms["frmMaster"].Text);

where "frmMaster is the 'Name' of the the form

Following is the the C# version of the solution given by"Ratnesh Rai" with minor changes.

string formtocall="frmMyForm";
System.Reflection.Assembly myAssembly = System.Reflection.Assembly.GetExecutingAssembly();
Type[] types = myAssembly.GetTypes();
foreach (Type type in types)
{
   if (type.BaseType.FullName== "System.Windows.Forms.Form") 
   {
      if (type.Name==formtocall)
      {
         var form = Activator.CreateInstance(Type.GetType("YourNamespace." + formtocall)) as Form;
         form.ShowDialog();
         break;
      }
   }
}

Solution 3

Iterate through the open forms like this:

foreach (Form form in Application.OpenForms)
{
    if (form is frmMaster)
    {
       // do something
       break;
    }
}

A little googling would have saved you months of time...
