It still generates a strong type internally, and without it Linq wouldn't really work - so, it's a good thing. It's not really akin to a variant.

Hi,

in my view it is as good as "continue" (or even "goto"): you can use it to your advantage and be fortunate to have it; and you can easily abuse it, it is all up to you.

It was added for Linq.

It gets abused too much.

Only weak programmers use it.

Instead of removing 10 char from right you can use split function
Because not necessary that always you have 10 characters after “?”,

string path = "http://www.bharathretail.com/cyberwing/update_ip.php?gid=4274725472424242";
string[] ar = path.Split('?');
MessageBox.Show(ar[0]);

either you count in base 21 (that would be unumvigintal), or your example is wrong.

if you want to get rid of the querystring in string s, use s=s.Split('?')[0];

Validation in Multilingual Application using c#

Hi,

I am working on Windows application and I created the validation for English language by using “RegularExpressions”. Now my application need to support Spanish language and my English validations are not working in Spanish.

If you're just using regexes, then you simply add Spanish-validating regexes to your Resources. Then use something like this:

if(Spanish)
    RegexValidate(SpanishRegex);
else if(English)
    RegexValidate(EnglishRegex);

Hi

Thanks for reply, but how to write "Spanish-validating regexes".
Because in English we use
"Regex objAlphaPattern = new Regex("[^a-zA-Z]");"

But what I need to write for Spanish.

Thanks

To be honest, I've not gone into regexes in detail. Spanish seems to use the same alphabet, plus some, so you could in theory use the same regex. I just don't know how to include the vowels with an acute accent and diaeresis. Perhaps this link may help

I don't think so. Rather than having lots of conditionals, just pull the regex expressions from a string resource, same as the GUI stuff.

I hadn't thought of that. Thanks for the tip. But how would you handle the case that a user wanted to change languages on the fly, apart from recompiling the application with the correct regex expressions?

I don't know the details and have no experience with the subject, however I do vaguely remember an article showing how a GUI language can be changed on the fly; it was based on those regional DLLs Visual Studio and/or .NET support for internationalization.

One probably would have to come up with another solution if one needed multiple languages on a Form, independent of the GUI language itself. Say a translator app.

How to access a file in different machine

The only way you can do that is if the folder containing the text file is shared, and the user logged into the pc that is using your program has the permissions to access that folder.

If these conditions are met you can just read the text file as if it was on the local machine. (path will be something like: \\sharedfolder\textfile.txt )

Of course if your asking for the actual code for reading a text file I'd normally tell you to go read a beginners book (on programming) since this is one of the most basic things you can do and every book handles it in one of the first chapters.

Load Type in DLL in a different AppDomain

Nandiator16-Jul-09 21:57

Hi,

First of all, excuse my English.
My app (Compact Framework) loads 2 copies if the same dll (exactly the same DLL renamed) using reflection.
The DLL should load the corresponding config file according to the DLL name (if the DLL is ModuleA.dll the config is ModuleA.txt, and so on).
My problem is this:
When I load the first DLL, everything goes OK, but when I load the second one when I do Assembly.LoadFrom( FullPath ) it loads the first DLL insteag of the 2nd one, despite the fact that FullPath contains the first DLL's path.
In addition there are the variables which shoul be global to each DLL. As everything is loaded from the first DLL, the globals are the first DLL's ones.

After looking for info I realised that what I need to do is to load each DLL in a different AppDomain, so they are isolated from each other.

To summarize:

One compilation: MyModule.dll
2 copies of the same DLL: MyModuleA.dll & MyModuleB.dll
One config file for each DLL: MyModuleA.txt & MyModuleB.txt
One appdomain for each DLL is needed.

Anyone knows how to do this in Compact Framework?

Here's a snippet from one of my classes:

name = System.IO.Path.GetFileNameWithoutExtension ( Filename ) ;

assm = System.AppDomain.CreateDomain ( name ).
    Load ( System.IO.File.ReadAllBytes ( Filename ) ) ;

Well I think the best option would be to create properties[^] in the form you want to pass them to and then set those properties with the values...

private string myProperty = "Default Value";

public string MyProperty{
get{return myProperty;}
set{myProperty = value;}//use the word 'value' here, do not substitute
}

you could also pass through a method[^] in the second form...

public void SetValues(string val1, string val2, string val3)
{
     MyVal1 = val1;
     //etc.
}

or you could have a list of static members[^] that all forms can access, but this may not be the best solution for what you want...

public static string Val1 = "My Val 1";

...all forms will be able to access this be reference the class/form is belongs to...

//inside form2
MyVal1 = Form1.Val1;

...hope that helps
