Topic: Trouble with console app to rename files

[Glenn R]

Chuck and Duh were right on the money and that was my guess from your stated problem Tim.

At the EOD (End Of the Day), all of Visual Studio's project templates and Options, really set options for the CSC.exe (C Sharp Compiler) behind the scenes. So, for instance, if you start up a project based on a WinForms template, it sets options that are passed to the CSC to tell it to compile the program as a Winforms exe...or console exe etc.

From what I know of #Develop, it does the same thing and the passes the correct arguments for your chosen application type to CSC.exe, to compile your program.

Cheers,
Glenn.

BTW Tim, your code writing has improved. That posted sample looks very good to mine own eyes.

One thing I would change:

Code: [Select]

SeriesPrefix.Length.Equals(14)

to this:

Code: [Select]

SeriesPrefix.Length == 14

Looking very nice though. Keep at it - it's actually quite a lot of fun isn't it?

Cheers,
Glenn.

Thanks Glenn, for the info and the comments on coding.

Yes it is quite a bit of fun.  I find myself looking forward to chances to write some C# code more than I do Lisp nowadays.

[Glenn R]

Heh. That reminds me of one of the many turning points for me, when I transitioned from lisp->VBA->C++->C#.

The next one you will find, is that you can code up something bigger, better, faster in C# than you can in Lisp 

Cheers,
Glenn.

Also, I forgot to mention:

C# Rulz and Lisp droolz.   

[T.Willey]

Here is the code that works the way I want it to.  I might clean it up when I have time, but for now this does what I want it to do, and fast.  I had 193 drawings that had to be renamed to match our standard, and this baby did it in less than one second.  My lisp couldn't even handle the sorting of names.

Example of a couple of the renamed files.

Code: [Select]

Renamed c:\test\test\EM3060030 (Z-ZDIST.8).DWG -> c:\test\test\12-2697-7156-9_177.dwg
Renamed c:\test\test\EM3060030 (Z-ZDIST.9).DWG -> c:\test\test\12-2697-7156-9_178.dwg

I like the way the .Equals() looks better.   

[Kerry]

looks nice Tim.

Glenn,
is droolz a local vocab' word over there 

aside:
The Mercury style shows the code without scroll bars ... just a tip.

[FengK]

I just selected class as the template.  I don't see a selection for console app.  Attached is the new file dialog from SharpDevelop.

Tim, did you click the "Windows Applications" node on the left?

I saw that after Cmdr posted, see quote below.  I didn't know that I had to start a new project, as I just started a new file.  I got it to work though.  Thanks for the help Kelie.

What version of SD do you have? this site shows SD with a console app option.  If you go to File->New->Solution do you get a console app option

No, it's not local Kerry...something I heard in OZ.
I am already using Mercury as per your suggestion a while a go - much better without scroll bars.

Cheers,
Glenn.
