.NET

[#1]

I have a VBA program that I have been using for years that I am unable to convert to vb.net. I figure before I start beating my head on the keyboard I would ask if anyone has anything similar. When I start a text/dim command, the routine changes my layer to my Dimension layer, like wise when I create a viewport. Anyone have something similar that I can look at the code.

I like what I see with A2k12 but all this vb.net stuff has me quite frustrated. So many programs to convert so little time

TIA.

Why would you want to do that through code ? Place the command on a ToolPalette and fill in the required layer. Far more flexible.

Hi,

set the sysvar CLAYER to your layer.

And if the layer does not exist, you have to create it before (as you did it with your VBA).

As all in the live you have to learn it and you have to get used to it. Yes ... vb.NET is different to VBA, but the more you get used to it you will see so much additional functionality and speed. Bear up - it's great then.

Because I'm old and resistant to change.

Actually, I am old school keyboard. I still use the PGP file extensivly. I have started using pallets primarily for blocks but find it quicker to type my 2 characters over looking for the appropriate icon. If push comes to shove I will look in that direction.

Thanks

I understand that, and am working on about a dozen company specific programs, but it is slow going. I am picking up bits and pieces as I go. As I mentioned in my OP, I was looking to see if someone else had already taken a stab at this so as to not have to start from scratch.

I remember the frustration when I started coding with VBA but I got used to it, the difference here is that I still had my old Lisp programs availible until I got something else working. With this I don't have the option to use the old while working on the new.

Thanks,

Kevin

I'm affraid your original post leaves a few unanswered questions that make it difficult for me to guess at exactly what you're looking for. 

ie. Do you mean that your VBA code "reacts" to the standard autocad text/mtext command and changes the layer, or is it a custom VBA text/mtext command, that changes the layer and then (fires the AutoCAD command or whatever)?

The best thing would probably be to post an example of your VBA code, then I'm sure someone here, myself or otherwise, will be able to help you get it figured out.

On a different note, I have been going at it with VB.NET for several years now, and I no longer have any code that uses the COM libraries (compared to the managed libraries, the COM interface is super slow), but to expedite the conversion process, if using the COM libraries in .NET, the code will be extremely similar to the VBA code, as in, you just copy the VBA code, paste it into your .NET project, and fix whatever errors come up, which will usually be minor errors resulting from the .NET code needing a different variable type, or some such thing.  (like variant => object)

For what it's worth, I don't like tool palettes either, or the ribbon.  They take up too much valuable screen real estate.

I myself agree, but our engineers like it because they can change them self a lot easier than the old MNS toolbars.

The screen size is not a problem because they all have 2 screens -- like in the early '80s

Can i ask you why you choose to VB.NET instead of C# ?

Yes, If I exicute a command (defined in the vba) the layer will change to the appropriate layer for that command and then revert to the previous active layer apon completion.

Watch out here it comes:

I have heard that But I am still trying to feel my way thru. As I do not have a lot of time to dedicate to training myself currently I will be looking at that as time allows.

AMEN!

SENL1362 -

I am an old school VB (4,5,6)  programmer, so for starters it's a "stick with what you know" kind of thing, but I looked into learning C#, and discovered that there was not really any benefit over VB, so I never bothered.

A lot of people talk about there being more code examples in C#, but first of all, I know C# syntax well enough to read the examples and see what they are doing, and there are plenty of online code translators to convert them to VB, so I'll just stick to VB.

[#10]

Thank you for answering. I too used VB(A) for the last 10 years and before that C and Fortran.

Last year started VB.NET but switched to c# because of the better examples and explenations to the how to questions specially when i comes to LINQ and Reflection.
