I am attempting to make a form public. I've start out with this class:[code]I can see the stupid form thru intellisense, but when this code is run I'm getting a null reference exception. I believe this is because the stupid form has not been initialized. I thought that placing 'new' in my class definition would initialize the form.
View 4 RepliesI had this incredibly ambitious goal to make a video game and so I am teaching myself/relying on kindness and knowledge of others as I go along. So far I have learned a lot, however needless to say, this is a monstrously difficult challenge, however one that I am very passionate about completing. The idea is that I am making a trading card style game and I was hoping that I could continue to use this thread and your kindness to keep me going whenever nessecessary throughout this challenge.So, here is where I am now. (Please forgive me if i have posted too much details/not enough details. Since I am new, I am not sure what information you need to help me. This will be corrected as time goes by and I learn more)I have created a card class with two properties. name and picture with name As String, and picture as PictureBox. the constructor looks like this: [code]
My next goal(and where I am currently stuck) is making i so that when the user clicks on one of the items in the listbox, a picture of the appropriate card(saved in a pictureBox of its own on a different form, and referenced in the card via the picture element) will be placed inside the empty picture box on the deckPage.
Im trying to make a basic Client/Server. The server can handle multiple clients and each client can send /recieve messages from the server.It works fine with just 1 client. but as soon as i connect with a second client. The first one no longer works. Anything sent from the first client is ignored by the server and when running the server in debug mode it gets errors from the client 1 stream.
Its as if the server will only hold one stream at a time and whenever another client joins the other streams are shut but the new client works fine. Even though i never close a stream.
[Code]...
Edit: FINALLY FOUND IT! Stupid mistake i forgot to put the ClientN variable up by one for each new client.So i was creating a new space in the array but erasing the first slot for the new client
I have a program where the main form is called (shown/activated) via a keystroke combination. When the form pops-up, I've set the focus to a textbox to begin typing right away.
When the keystroke event occurs, I have:Me.Activate()And in the Form_Activated event:
Textbox1.Focus() Simple right? It works the way I want it to, even after I've compiled and run the EXE, but ONLY if Visual Studio 2008 is running. Once I close my project in VS, with the program still running outside VS, the form is shown, but input focus is not set to the textbox.
Input focus is however still set to whatever it was previously, like a word document for example. My form will be topmost, but if I attempt to input text, it would still be entered into the word doc. why having my projects' source open in VS has anything to do with running the compiled EXE of said program?
I've even tried API calls to SetForegroundWindow and ShowWindow with the same result.
Im attempting to make a "Licensing" system, but I dont know where to start. I know I would need some sort of "database". Heres the basic idea of what I would like my program to turn out. "License" creator: -I give a "permanent" ID Generator to someone -They get an ID that only works for their computer, and doesnt change unless the computer is changed -They give me their ID -I input the ID into a "database" -Program creates a "License" file using the "permanent" ID Main Program: -Loads the License File -Checks if the License is a valid file (using the database)
View 2 RepliesI'm trying to make a public array that I can use in Form1.vb and module1.vb.
It seems to work fine in Form1.vb but module1.vb complains about that it isn't declared.

Public Class Form1
Public SuffixArray() As String

Is there any way to make a class instance public?In my mainform I define an instance of a certain class and then later on in some other forms which appear I want to alter this class.I try and pass them through when creating new instances of these other forms and it tells me Error3<instance of the class I want> cannot expose type <the class> outside the project through class <the form I want to edit it with>Which I gather from documentation is about it defeating the purpose to have a private class suddenly be thrown aroudn.but then how do I make it public? I can't define it in the first place as public myXClass as XClass, it only accepts private.

ok basically i was trying to make a Control that exposes its protected properties to the public. example, you could call the protected DoubleBuffered property publicly. the problem is that this class called ExposedControl must be compatible with the type System.Windows.Forms.Control, meaning i should be able to create an ExposedControl using an existing Control so i had something like this in the constructor.

I have a class inside a class.I need to expose the properties of the 2nd class to other classes, therefore it is public.However, I do not wish other classes to be able to create instances of this 2nd class, it should only be instantitated from its parent class.I thought I could resolve this issue by making the constructor of the 2nd class private, but this even prevents the parent class from instantiating its child class! How can I work around this, do I have to make the constructor public and allow anybody to create an instance of the class?

I have a couple of PUBLIC SUB's on my Form1. Is there a way that I can execute them on Form1 through another Form / Button-click? I am using a Dialog1.ShowDialog() for configuring some settings for my application. Now, I have most stuff on my Form1 set / loaded via PUBLIC SUB's (for example THEME SETTINGS, DROPDOWN LIST values and so on), and if I change something in the Dialog1 this Subs need to be executed again ...
Before my explanation gets too complicate, here a sample with a simple SUB:
Asume you have a Form1 with a Button1. On Button1Click a Dialog1.ShowDialog will be executed. In addition you have the following PUBLIC SUB on Form1:
Public Sub ShowMessage()
MessageBox.Show("Hello World!", "Message:", MessageBoxButtons.OK, MessageBoxIcon.Hand)
End Sub
How could I execute this Sub on Form1 from Dialog1 (maybe on a ButtonClick event)?
