I just wonder if the couold be some explanation added as to where exactly in code we add those overloads. On the side of calling procedure or called function? Very well, thank you.

I would like to know how to pass variable to form before creation of this form. I want to pass object which represents important data and then to perform some actions on form with this object. So I want to have form for user and for visual purpose no for variables and performing actions. For this purpose I have mentioned object. I dont know how to pass variable to form which is Startup form. I want to have SDI application and this form must be as Startu form. One solution is to create second from, set it as Startup form and call my first form. In C# it is simple - there is Program.cs and Application.Run so I can call Application.Run(new frmC_Main()); But VB? There are Application.myapp and Application.Designer.vb files, but how to call something similar to C#? Thx in advance. ...MUDO... Hi.

I am a newbie to programming.it would be of great help if you make a demo project with source code available,so that a person like me can get a very clear picture of the solution you suggested.Also if you have the other way around soultion available to compare with the solution you suggested.

I also use the arguments passed in to set up the form to edit a record or add a new one. So if i pass CustomerID with 0 then the form go's into an add new mode.

Once I re-arranged that code, everything works perfectly now. Thanks!

I've used your method with much success. Now, though, I've run into a problem and I wonder if you have an answer. I've added the arguments to the Sub New sub in a form that contains several Public subs that get called from other forms. For example: In Form1 I have code that calls a public Sub in Form2, but once I changed Form2 to accept arguments, I can no longer access those public subs in Form2 from Form1. I was able to solve that (sort of) by declaring the public subs as Shared, but that has caused a problem when the Public Shared sub is showing Form3. It used to create a new instance of Form3 each time, but now it opens only 1 Form3 and shares it between Form1 and Form2, which I don't want. I guess my question is, why do I lose the ability to call Form2.SomePublicSub from Form1 after I change Form2 to accept arguments? Thanks for a great article. I give it a 10+. Great article.

Typically you'll see this kind of thing happen when either a new object/control instance is created or a new array or dataset is created accidentally. Creating objects in different threads can also cause this to happen. The best thing to do is just walk through your code to see if there is any place where you might be accidentally initializing an object. If nothing stands to you, debug it and step through it. You'll probably find the culprit lines of code when you do that. Hi Paul,

Form-to-form works ok, it's only module to form that doesn't. Any ideas? I’m trying to load a combo box and a list box in a form from code in a module but the data never gets there.
