I'm just wondering, how do i make a class link into my main code, it is in the same project so no need to reference it
Ive set up the the class and typed
code:
But they aren't linking/ working.
I an trying to create a GUI and I have added a menu strip, under the tools section of the menu strip, I have added a settings option. I want to click settings and have it open another windows form linked to the main windows form with the menustrip in order to set certain parameters. How do I link these two boxes using the settings menu strip?
View 1 RepliesAs of the moment I have 24 buttons that are keys to a piano.24 of the button codes have a call method that calls the note to be played.24 of the private subs that are called have an .wav audio playback command within them. I was hoping I could move the .wav private subs into a separate class, and just call them from my main form, therefore cleaning up the lines of code I have at the moment. [code]That example only counts for one Button "The Key of C", and the audio file that is called with it. Multiply that by 24 and you get a big mess of repetitive junk.Can I move the audio subs into a class and call them from my main form?
View 16 RepliesIn VB6 I always wrote my apps using Sub Main as the starting point. I see in .NET I'm able to wrap it in a shared class (see [URL] for example). However, the downside is that I can't declare any class-level variables, because of course the class is never instantiated. Being shared, it limits what the code can do. So, any benefit to use a shared class and shared sub main which I'm missing here.
Otherwise it seems using a module (as in VB6) provides a lot more flexibility. Of course, I should also ask if "Application Framework" is really the way to go for real-world apps, or if it's only there for beginners and real-world coders turn it off and use Sub Main instead? If so, how are the events "UnhandledException" and "NetworkAvailabilityChanged" done if App Framework is turned off?
I want to start building my first large program. I want to create scripts on their own and allow them to interact with my main sub. I guess if I need a "plane" in my application, that could become it's own class? If I wanted to calculate "purchases", "money" I could create a DLL? I don't want to have to change things and have to recompile my entire application every time I want to change how something works for example.
View 5 RepliesI'm busy creating a multi language application, so far so good. I've googled some examples, first problem I've encountered is setting it. Accourding the msdn documentation it had to be done BEFORE initializecomponent. I didn't know how, but found out you have to creat a 'sub new' in your main class.

I have never made a notepad like program just calculators and felt like learning how to link/find the parts to make save, open, format, and some other extras but I have NO code. I can't move on unless I know the parts needed and what the code for one of them is if I can link the save as button on the menu bar to the part needed to save I can figure the rest out besides the format that it saves in.
View 1 RepliesI created a report [RptContacts] to show the data of all the contact persons in my SQL server database.
The report has a row group on the column [PK_Contact] in the datasource (IQueryable).
An other report [RptCommunications], which will serve as subreport in the main report, shows all the communications we had with each contact person. The datasource (IQueryable) for this report contains the column [FK_Contact] referring to the contact person with whom we had the communication.
I added [RptCommunications] as subreport to [RptContacts]. In de Subreport Properties/General, I indicated both under "Name:" and "Use this report as a subreport:"RptCommunications.
How can I make sure that for every value of [PK_Contact] in the main report [RptContacts], I see the correct records in the subreport [RptCommunications] corresponding with the right contact person. In other words, how can I make sure that for every communication in the subreport, [FK_Contact] = [PK_Contact] in the main report?

View 2 RepliesI have a link here that works perfect for calling the postback close that I need to happen:
<a href="javascript:parent.__doPostBack('Close','')"><asp:Label ID="Label5" runat="server" Text="Close Me"></asp:Label></a>
However, I would like to be able to call the *javascript:parent.__doPostBack('Close','')* method from the code-behind file rather than the user clicking the link. I.e., when I have completed my tasks in the application code, call parent.doPostBack as my last function call, which closes the window in question.

View 3 RepliesWe have a Dell laptop used to run an in-house VB.NET program. It got a virus. We had to wipe the hard drive and reinstall Windows from scratch. We use Windows XP Pro, which is what was installed on it before. But now our VB program won't run. After trying and despairing of getting remote debugging to work, I actually installed Visual Studio 2005 on the machine, just long enough to get information about what was making the program fail. And the failure was most peculiar. It isn't in our code. It's in the VB setup code that loads the main form. And it says, "Error loading form: class not registered."The gory details are given below. Now here's the strange thing. Not every VB.net program fails on this computer. And the program that fails, fails only on this computer; it has run successfully on several other Windows XP systems with .NET Framework 2.0 installed.[code]

I'm trying to serialize the main class in my VB solution. I've added the Serializable attribute at the top of my class like so:
[code]...
I'm guessing this is because you can't serialize the form that is attached to the class or something, but I really don't know what I'm doing. Can I serialize all of the objects contained in my Form1 class somehow, without getting this error? I don't want to store any data about the form controls, I just need to save all the objects that I've defined at the top of the Form1 class.
