Re: Some issues in strong naming .net dlls

15-Feb-07 15:20

Hi,

AFAIK an exe or dll can only obtain a strong name if all other dlls it needs also have
strong names; as a result you buying a strong-named dll should not force you to do
anything, it must be perfectly possible to use it in a non-strong-named environment.

The rationale is: strong naming exists to protect an app; a protected app must be
unwilling to rely on a dll that may have been tampered with, hence it requires its
referenced dlls to be strong named, but not the other way around.

Hope this helps.

thanks Luc

well its being referred to in an assembly and therefore i need to strong name it as well.

any how i managed to get the issure resolved it was a bad entry in one of the config files that referred to unsigned version...

thanks though

I am however able to instantiate and use classes from this assembly without errors..

Any ideas in getting intellisense to work with this assembly..

Thanks

Hi,

the Intellisense info is collected in a separate xml file, provided you enable this
feature (by specifying the file name) in the project's properties.
It remains available as long as you keep the xml file next to the dll file itself;
referencing the dll file in another project makes Visual look for the xml file in
the same directory.

Hi Joel,

Member names are available to Intellisense as soon as you have provided these two:
- a reference to the dll file (Add Reference... in Solution Pane's context menu)
- a using statement (at the top of your C# source files).

Warning: you see method names only if:
- you have a class instance name for non-static methods; e.g. FileInfo f; f.Open();
- you have a class name for static methods; e.g. File.Open()

The extra info you can add with triple slashes goes into an xml file, cfr my previous message.

Int and string values

I have an aplication with a media player control . Im trying to get it to load the last played file when the application is run again . ive allready used the code below to set the path to the last file the media player played .

// Set last url
Microsoft.Win32.RegistryKey key;
key = Microsoft.Win32.Registry.LocalMachine.CreateSubKey("SOFTWARE\\Flexbeta\\VideoDesktop");
key.SetValue("LastFile", SelectFile.FileName);
key.Close();

The problem is when i try to use the int value LastRun to control the media player control i get the folowing build exception "Cannot implicitly convert type 'int' to 'string'" because MediaPlayer.URL requires a string value . Im looking for a way to use the int value LastRun as the media player URL

//Load the last file
Microsoft.Win32.RegistryKey key2;
key2 = Microsoft.Win32.Registry.LocalMachine.CreateSubKey("SOFTWARE\\Flexbeta\\VideoDesktop");
key2.GetValue("LastFile");
int LastRun = (int)key.GetValue("LastFile");
MediaPlayer.URL = LastRun; <-- problem !!!

Any ideas ?

Use static methods of int class. int.Parse or int.TryParse

Why on earth are you trying to use an integer as a file name in the first place?

Hi,

I expect the line
key.SetValue("LastFile", SelectFile.FileName);
stored the file name as a string.

And I expect MediaPlayer.URL needs a file name, hence a string too.

So I dont understand why you want to use an int LastRun ?

I would try
string LastRun = key.GetValue("LastFile");
MediaPlayer.URL = LastRun;

Can anyone figure out the issue

Are you storing the date in a neutral format such as UTC?

only two letters away from being an asset

Luc Pattyn15-Feb-07 9:36

15-Feb-07 9:36

Yep, date formats are a popular reason for failure.

What is 01/02/03 supposed to mean if you are not sure which date format is used ?
And which of 28/02/03 and 01/31/03 does not exist (and will cause a Parse exception) ?

So best is to use a universal format (such as UTC), independent of what will be
input/output to the users.
