Re: clicking "Open with" when multiple files are selected

7-Jan-04 20:38

At least from what I can tell on my installation, Textpad doesn't really support opening multiple files with "Open with...", it creates a new menu entry (shell) for launching it.

I know Winzip and Winrar create a bunch of new shell commands as well, which is different than using "Open With...".

Are you actually selecting two files, right clicking them, selecting "Open with...", and then picking Textpad as the program and having it open both? If so, my installation doesn't do that...

Yes, you're correct. I was using the menu entry instead of "Open with" and I had just assumed that Textpad would work the same way when using open with as it does with it's menu entry. But apparently not.

I guess now my question would be how to make a shell entry that would work like that. Any tips on how to go about finding out what files are selected?

Thanks,
Blake

Take a look at this article.

(It's in C++ but I'm not sure if some of these things are even possible in C# without Interops. It will give you a good starting point.)

OK, I guess I'm just stupid, but. I have a C# app that I created and want to send it to someone else. What needs to be sent along (with the .exe) so they can run it.

Thanks.

Well, generally if that person has .NET framework installed on his/her machine it will works, but if your program has configuration,database files or using custom assemblies it should be shiped with exe file,so typically it is better to create Set up project for your projects and add your settings and file to it and ship installshield only,not only the exe file.

1) Create an installer for your app in VS.NET

OR

2) No installer

First of all, the .NET framework should be installed on the target computer. Include dotnetfx.exe it's on the component update disk / prerequisities disk of VS.NET...

Next thing to do is to check te references. If all references are made to files of the .NET framework you don't have to include any more files. If you have used custom .NET dlls (in app directory if you have chosen copy local) or COM dlls (via interop) you should include these in your distribution (COM: dll AND interop dll files, interop files are in your app output dir, main dll can be anywhere)

Regular Expressions

I am using the RegEx which needs to check for the value to be five digits before the decimal and 2 after the decimal or just five digits. and I am using
System.Text.RegularExpressions.Regex exp = new System.Text.RegularExpressions.Regex("(^\\d{0,5}.{1}\\d{1,2}$)|(^\\d{1,5}$)");
With this it's only checking if the value is five digits before decimal and 2 after but not for just 5 digits. I entered 6 digits without decimal and it did not catch the exception.
I don't know what's wrong. Any help ?

In most regular expression syntaxes, "." is a symbol that means "any character". You probably need to escape the . with a backslash, like "\.".

^\d{5}(\.\d{2})?$

You didn't escape ".". Without escaping, this means that it matches any character or none. For instance, to match any 5 characters, you could use .{5}.

I'm pretty sure you know this and just had a brain fart while typing, but for anyone else reading this...

. actually means any character except possibly "\n" depending on options you set for your regular expressions. In other words, it doesn't match "none". More details here.

You're right - brain fart! Smile | :)

I'm so used to typing .* for so many things I practically think of it as a single pattern element! Poke tongue | ;-P

Thanks for the catch!

I think I would write this as:

@"^\d{5}(\.\d{2})?$"

Well, actually, I'd write it as:

@"^
\d{5} # 5 digits
(
\. # decimal point
\d{2} # 2 digits
)? # match zero or one time
"

and then use RegexOptions.IgnorePatternWhitespace

(it wasn't clear to me if you meant "only 5 digits" or "from 1 to 5 digits" in your description, so you might need to change the first part.

I have changed my code and it works. Actually it supposed to be 1 to 5 digits, so I changed the first part to \d{1,5}

I need a book/document/article/website that could detail (regardless of the programming language, if required for examples) how the Windows operating system exactly works internally.

Is there such a thing? I believe I cannot become a better programmer until I start understanding this: how the OS I'm coding for is actually behaving/responding to this code.

I don't think you can find a book for a whole of windows cause it has very very different parts,also it is not open source ,so I'm not sure you can find out exactly all parts for that. But you can get some information if you want to work on a specific field ,you can get a book specially for that part. For example you can find out a lot about securities and how windows security acts in a books that specially about this topic. Same about other field.There is no general book for general purpose I think.

learn to program windows in c

Once you've spent a couple of years writing your own message loops and finding out just how many windows it really takes to do the simpliest things, you'll know how it works.

Admittedly given most of todays languages and programming jobs the knowledge will be next to useless but it can have its rewards.

Great comment. Just reading a book on C windows programming will help. Writting even a few simple apps will give you a real good idea what is going on.
