[RESOLVED] Help - design view for classes

[Iainn]

Hi!

I'm very new to VB and have ran into my first problem. I am trying to change the design layout of some classes, but I cannot open them in design view - only the first one is visible. I've tried everything I can think of, but can only design the first class and none of the others.
I got the code from someone else who I know is also learning and I just pasted the code into the form1.vb page.

Thanks to anyone that can help!

classes don't have a design view unless they are derived directly from containercontrol.

the classes that do this are

System.Windows.Forms.Form
System.Windows.Forms.PropertyGrid
System.Windows.Forms.UpDownBase
System.Windows.Forms.UserControl

since you are just starting out.. that probably doesn't make too much sense to you, so why don't you tell us what you are trying to accomplish, and then we can help you better.

I have 4 classes which use Inherits System.Windows.Forms.Form. However, I can only design the layout of the first one. The others just don't show up. When I run my program, everything works fine, I just can't alter the design of the 3 other classes.

[kleinma]

post the entire code from one of your forms that is not working.

[Iainn]

I also included the extension file as well, if you are trying to run it. It is 'A' I am working with, although that's not important.

[kleinma]

It works ok for me.

I created a new project, and added a reference to KnobControl.dll from the controla folder in your zip file. then I took your code and pasted it into a blank .vb file, and i am able to switch between code view and design view no problem.

[Iainn]

Yes, I can do that too. But how can I change the design layout for the other pipes? Also, thanks for your speedy replies!

[kleinma]

I guess maybe I am not sure what you are unable to do?

are you saying you want to be able to modify the layout of the actual knobcontrol that you added to the form?

[Iainn]

Ah, no. If you run the program, you can select 4 different things from the menu. If you select any of them, they load no problem. However, I cannot edit any of the layouts, excluding pipe 1, in the design view. No other ones can be edited.

[kleinma]

You only posted the code for Pipe1 though...

[Iainn]

???

There are 8 classes in the txt file, each with full code.



All I want is to change the layout of Pipes 2 and 3 (and also the panel which is not shown). I cannot do this graphically, as they do not show up in the design view.

[kleinma]

ahhhhh.. I see now.

Well you can't do that

You need to make a seperate .vb file for each form. Then you will be able to modify the layout of each form.

Infact unless the class itself is inside another class (nested classes), its is generally bad practice to have more than 1 class in a .vb file.

It makes it very cluttered and hard to work with especially on big projects.

Yes, I have now got it to work! Many thanks for persevering with me! I owe you a drink or 2 man. In fact, make it 3!

Nice. I like Rolling Rock and yuengling

And I'm not even from PA... go figure
