Can I create windows form by using late binding?Hi,
I have a database table field to store the form name, I want to create the particular windows form by using the value that read from that DB field. For examples, the table field has a value "ThisForm", then I want to create the form with class name "ThisForm" (Suppose I have already defined the class "ThisForm"). Can I do this by using late bindnig? Any source code for reference? Thanks! Steven. Steven,
You have a form and you want to give it from the database the name from this field. And then? This sounds for me as me = dr("ThisForm") http://msdn2.microsoft.com/system.windows.forms.control.name.aspx Not that it does something or is usable in your program, however that is it.

change the name of the form. For examples, I defined 3 windows form in my VB code which have name "Form1", "Form2" and "Form3". Which form I need to display in screen is depended on the field in the database table. Can I do this by using late binding? Coz I don't know which form I need to create before doing the database query.

Note: 1) "Assembly" is in the System.Reflection namespace. 2) "name" must to be qualified with the namespace of your application (by default, in VB, it's the same as your project name): "MyAppName.Form1" Show quoteHide quote "Steven" <a@a.com> wrote in message news:epye0%23HLGHA.668@TK2MSFTNGP11.phx.gbl... > oh, sorry.
