Some issues in strong naming .net dlls f4hd15-Feb-07 9:48 f4hd 15-Feb-07 9:48  Hi, I am trying to use a particular dll bought from a company that has a strong name. As a consequence had to give a strong name to all the dlls involved in the project. Among the external Dlls that I'm using are the following microsoft application block dlls: Microsoft.Practices.EnterpriseLibrary.Caching.dll Microsoft.Practices.EnterpriseLibrary.Common.dll Microsoft.Practices.EnterpriseLibrary.Configuration.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.dll Microsoft.Practices.EnterpriseLibrary.Logging.dll so I had them strong named using mycompany.snk key as well which went successful. And once I referenced them properly in the project it compiled without any problems. So far so good. However when I access the Cache Factory while loading the application I get the following error: ------------------------------------------------------------------------------------------------------------ An unhandled exception of type 'System.IO.FileNotFoundException' occurred in microsoft.practices.enterpriselibrary.configuration.dll Additional information: File or assembly name Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, or one of its dependencies, was not found. ------------------------------------------------------------------------------------------------------------ Any ideas why this is happening and how may I go around it, have been stuck with this issues since ages.... Regards, Fahd Re: Some issues in strong naming .net dlls Luc Pattyn15-Feb-07 15:20 Luc Pattyn 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.

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 Joel JO Re: Intellisense and DLL Luc Pattyn15-Feb-07 9:29 Luc Pattyn 15-Feb-07 9:29  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. Luc Pattyn Re: Intellisense and DLL DISP-Jol16-Feb-07 4:17 DISP-Jol 16-Feb-07 4:17  Luc,, Thanks for your input...I dont wanna document or specify additional information for my classes.I just want the constructor name and signature to show up when I an using object of this class.. As in MyClass tstClass=new (I want MyClass name and the overloads for the constructor to automatically appear here) Thanks Joel JO Re: Intellisense and DLL Luc Pattyn16-Feb-07 7:51 Luc Pattyn 16-Feb-07 7:51  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. Luc Pattyn Int and string values Raymond_P*15-Feb-07 8:27 Raymond_P* 15-Feb-07 8:27  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 ? Re: Int and string values mehrcpp15-Feb-07 8:42 mehrcpp 15-Feb-07 8:42  Use static methods of int class. int.Parse or int.TryParse Re: Int and string values Raymond_P*15-Feb-07 8:52 Raymond_P* 15-Feb-07 8:52  \Can you give an example ive never tried this before Re: Int and string values mehrcpp15-Feb-07 9:43 mehrcpp 15-Feb-07 9:43  int iTmp = int.Parse("8"); Re: Int and string values Guffa15-Feb-07 9:31 Guffa 15-Feb-07 9:31  Why on earth are you trying to use an integer as a file name in the first place? --- single minded; short sighted; long gone; Re: Int and string values Luc Pattyn15-Feb-07 9:32 Luc Pattyn 15-Feb-07 9:32  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; Luc Pattyn System date problem Harikrk15-Feb-07 7:51 Harikrk 15-Feb-07 7:51  I am using windows xp as my OS. set the system time format as US format. I have developed an application in c# with msssql server as back end. When i change my system date format as UK format (dd/mm/yyy) i am getting the application crashed. The error is comming in the sql query to insert into db. It shows the date is overflow. Can anyone figure out the issue regards hari aspspider.net/rkharikrishnan Re: System date problem Not Active15-Feb-07 7:55 Not Active 15-Feb-07 7:55  Are you storing the date in a neutral format such as UTC? only two letters away from being an asset Re: System date problem Luc Pattyn15-Feb-07 9:36 Luc Pattyn 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. Luc Pattyn Re: System date problem Harikrk15-Feb-07 14:37 Harikrk 15-Feb-07 14:37  thanks for teh reply. can you tell me how i can use UTC format. I am having datetime pickers in my form and also i have to use current date Re: System date problem Luc Pattyn15-Feb-07 14:52 Luc Pattyn 15-Feb-07 14:52  Hi, there are actually two issues: - time zones: if you want to be able to exchange files that contain time info around the world, the app must understand how to handle differences in time zone. That is what UTC offers a good solution for (see some of the DateTime methods). - formats: if you want your app to understand date/time strings in a file, you can not rely on the system's datetime format during parsing to correspond with the one used during writing that info (on same or other machine, by same or other user, with regional settings maybe changed, etc). There are some articles dealing with these issues here on CP, try a search. A found at least one that seems relevant.[^] Luc Pattyn i am looking for a DLL file for a webcam marwan_siala15-Feb-07 7:12 marwan_siala 15-Feb-07 7:12  i am looking for a dll file which will enable me to record from a mic from sound card and video from a webcam and coding them to (for example mpeg, mp4, avi, ...) and send them through the network to specific host ... so the host can decode the received data ,preview it, and save to a file.... all these by using C#.net 2005 and the HELP document for the DLL file if available...
