如何举办活动? [英] How to raise events?

问题描述

您好，我有一些有趣的代码正在尝试解决，但是即时消息是从C#到VB.net转换.

Hello I have an interesting bit of code which I am trying to fix but the error im getting is from a C# to VB.net conversion.

Error	1	'Public Event CurrentPath(hive As String, path As String)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.	C:\Users\Admin\Desktop\Registry Cleaner VB.NET\Form1.vb	287	9	VTRegScan

有问题的代码是:

the code in question is:

_RegScan.CurrentPath += New cRegScan.CurrentPathDelegate(AddressOf RegScan_CurrentPath)

在代码_RegScan中是:

in the code _RegScan is :

Private _RegScan As cRegScan 'which is a different class within the project.

currentpath是:

currentpath is :

Public Event CurrentPath As CurrentPathDelegate 

导致currentpathdelegate为:

which leads to currentpathdelegate which is :

Public Delegate Sub CurrentPathDelegate(ByVal hive As String, ByVal path As String)

我可以提供有关该代码的最后一部分的信息是RegScan_CurrentPath，它是一个私有子目录:

The last section of this code that i can give information about is RegScan_CurrentPath which is a private sub :

Private Sub RegScan_CurrentPath(ByVal hive As String, ByVal path As String)
           _sHive = hive
           _sPath = path
       End Sub

在私有子配置单元和路径中是字符串和_sHive，_sPath ="


对于这个问题，我该如何纠正这个问题以引发事件?

提前谢谢！！





C#中的代码就像这样....

within the private sub hive and path are strings and _sHive , _sPath = ""


For this question how might I correct this problem to raise the event?

thank you in advance!!





The code in C# is like so....

private void InitFields()
       {
           _RegScan = new cRegScan();
           _RegScan.CurrentPath += new cRegScan.CurrentPathDelegate(RegScan_CurrentPath);
           _RegScan.KeyCount += new cRegScan.KeyCountDelegate(RegScan_KeyCount);
           _RegScan.LabelChange += new cRegScan.LabelChangeDelegate(RegScan_LabelChange);
           _RegScan.MatchItem += new cRegScan.MatchItemDelegate(RegScan_MatchItem);
           _RegScan.ProcessChange += new cRegScan.ProcessChangeDelegate(RegScan_ProcessChange);
           _RegScan.ProcessCompleted += new cRegScan.ProcessCompletedEventHandler(RegScan_ProcessCompleted);
           _RegScan.ScanComplete += new cRegScan.ScanCompleteDelegate(RegScan_ScanComplete);
           _RegScan.SubScanComplete += new cRegScan.SubScanCompleteDelegate(RegScan_SubScanComplete);
           _RegScan.ScanCount += new cRegScan.ScanCountDelegate(RegScan_ScanCount);
           _RegScan.StatusChange += new cRegScan.StatusChangeDelegate(RegScan_StatusChange);
          
       }

public event CurrentPathDelegate CurrentPath;

private void RegScan_CurrentPath(string hive, string path)
       {
           _sHive = hive;
           _sPath = path;
       }

#region Delegates
       public delegate void LabelChangeDelegate(string phase, string label);
       public delegate void CurrentPathDelegate(string hive, string path);
       public delegate void KeyCountDelegate();
       public delegate void MatchItemDelegate(cLightning.ROOT_KEY root, string subkey, string value, string data, RESULT_TYPE id);
       public delegate void StatusChangeDelegate(string label);
       public delegate void ProcessChangeDelegate();
       public delegate void ScanCountDelegate(int count);
       public delegate void ScanCompleteDelegate();
       public delegate void SubScanCompleteDelegate(string id);
       #endregion

       #region Events
       [Description("Status update")]
       public event LabelChangeDelegate LabelChange;
       [Description("Current processing path")]
       public event CurrentPathDelegate CurrentPath;
       [Description("Key processed count")]
       public event KeyCountDelegate KeyCount;
       [Description("Match item was found")]
       public event MatchItemDelegate MatchItem;
       [Description("Processing status has changed")]
       public event StatusChangeDelegate StatusChange;
       [Description("Processing shifted to new task")]
       public event ProcessChangeDelegate ProcessChange;
       [Description("Task counter")]
       public event ScanCountDelegate ScanCount;
       [Description("Scan Completed")]
       public event ScanCompleteDelegate ScanComplete;
       [Description("Scan Completed")]
       public event SubScanCompleteDelegate SubScanComplete;
       #endregion

我希望我已经提供了足够的解决方案，谢谢您..

I hope I have provided enough for a solution thank you..

推荐答案

您始终可以仔细阅读错误消息.它并不能完全向您隐藏解决方案:

You could always read the error message carefully. It doesn''t exactly hide the solution from you:

is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event

因此，用于"RaiseEvent"的快速Google会将您直接带到MSDN: RaiseEvent [ ^ ]通过280,000页的信息列表.

将来，请尝试至少自己进行基础研究，不要浪费您或我们的时间.

So a quick google for "RaiseEvent" will take you directly to MSDN: RaiseEvent[^] via a list of 280,000 pages of information.

In future, please try to do at least basic research yourself, and not waste your time or ours.

请提供C#代码，以便在此之后我可以提供适当的解决方案.

Please provide C# code so after that I can provide proper solution.
