.net - Handle events in another class -

-

I'm trying to move some code to some class files to clear my code. An area with which I'm having trouble is reporting the progress of events between the work and the object of a progress bar.

I think the event work has to be put in the new category, but they need to update the progress bar on the calling form? Can Event Class \ object back instead of handlers Update

The current form all code is: 

  function DoRestore (ByVal SQLServer string as string as ByVal BackupFilePath , ByVal DatabaseName as string) dim server = new server ServerkConnectionContextkApplicationName (as SQLServer) = Application.ProductName dim race restore = new restore (in) dim DataTable res.Devices.AddDevice (BackupFilePath, DT as DeviceType.File) Dt = res.ReadFileList (server) res.Database = DatabaseName res.PercentCompleteNotifi Cation = 1 AddHandler res.PercentComplete, Address Off RestoreProgressEventHandler AddHandler res.Complete, AddressOf Restore Complete EventHandler Res.SqlRestoreAsync (server) res.AsyncStatus.ExecutionStatus = ExecutionStatus.InProgress application. DoEvents () Ending while Expiration Function Private Function RestoreProgressEventHandler (ByVal this object as a result, as ByVal e PercentCompleteEventArgs) 'update progress bar (e.Percent) end function Private sub RestoreComp leteEventHandler (ByVal as the object, as ByVal e Microsoft.SqlServer.Management.Common.ServerMessageEventArgs)' Signal Completion via End Sub   
 The area used:  
  DoRestore (SQLServer, "C: \ SQLBACKUP.bak", DatabaseName)    
 
 
 should you define an event in your class and handle updates of the progress bar in the form (assuming WinForms?) - this issue is that the class relates to supporting something There should be no concept of progress bars:  
 Define the incident in the category:  
  Public Event Report Progress (East Bilateral progress as Ank)   
 The time required to backup extend this event:  
  RaiseEvent ReportProgress (value)   
 In the calling code you either need  
     
  •  
     Define a class using  with Events :  
     < code> backup personal Bakavent backup as Class   
     and then act on this event:  
      progress as Private sub backup _ReportProgress (integer) Backup backup Report Progress Debug WrightLine ("Progress:" + Progress.ToString) End Sub    
  •  
     Or Manually Add a Handler:  
      Personal Debug Reporter Progress Handler (progress as integer) Debug. WrightLine ("progress handler:" + progression.tostring) Add End Addendum Backup. Report Progress, Address Backup_ReportProgressHandler

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
