Errors

[Pedant]

Hi,

I am trying to learn vb.net.

I have just started my second program, however it complains that "\MainForm.vb(27) : error BC30002: Type 'Size' is not defined."

"Me.AutoScaleBaseSize = new Size(5, 13)"

If I try to compile it via command line (I had to add a path to vbc.exe in my environment variables) it throws up multiple errors

I am using SharpDevelop. Could someone give me a hand please?

Thanks.

SharpDevelop, I don't think anyone here uses it. The error you got about Size should not have happened.

[Pedant]

Does anyone use command line then? I think my .NET sdk may nto be properly installed or something as I would have assumed that environment variables would have been set up if it were?

Thanks.

You need to use the /reference:System.Windows.Forms.dll,otherfiles.dll commandline when compiling, if you're not already. Make sure you reference the proper DLLs.

Well, this showed an improvement :) "\Desktop\vb code>vbc /reference:System.Windows.For

ms.dll /t:exe /debug+ /optionstrict+ /out:.\HelloVB.exe show.vb"

 

has different errors now.

 

"\Desktop\vb code\show.vb(12) : error BC30456: 'Sho

wDialog' is not a member of 'Main.MainForm'.

 

fMainForm.ShowDialog()

~~~~~~~~~~~~~~~~~~~~

\Desktop\vb code\show.vb(18) : error BC30007: Refe

rence required to assembly 'System' containing the base class 'System.ComponentM

odel.Component'. Add one to your project.

 

Inherits System.Windows.Forms.Form

~~~~~~~~~~~~~~~~~~~~~~~~~"

etc. I looked and ShowDialog "Overloads Public Function ShowDialog() As DialogResult" and DialogResult is "(in System.Windows.Forms.dll)" which I include so I could do with some more help please.

Thanks

You should also reference System.dll.

Almost perfect :) a good thing since I am about to hit my bed. However, I am not up to the stage where I was in SharpDevelop

// Scratch that.

 

Perfect, included System.Drawing.Dll and it compiles happily now. Bedtime methinks. Is there an easier way of finding dependencies other than the .Net Framework SDK?

Thanks a lot, Hopefully I will get somewhere tomorrow.

Im not sure if thats what you mean but you can check in what assembly anything is by looking at the description of each class in the documentation. On the bottom they have a line thats says: "Assembly: name of the dll".

That is what I was looking at, I was wondering if there was maybe a -simple- diagram somewhere which showed dependencies.
