c# - How to use this WndProc in Windows Forms application? -

-

Please guide me how to use this WndProc Forms in Windows: 

  private IntPtr WndProc (IntPtr hwnd, int message, IntPtr wParam, IntPtr lParam, handled bool ref) {if (msg == NativeCalls.APIAttach & amp; & amp; (uint) lParam == NativeCalls.SKYPECONTROLAPI_ATTACH_SUCCESS ) {// Make the Skype window netic call to the current handle. HWND_BROADCAST = wParam; Handled = true; New Interrupt Return (1); } // Skype sends our program messages using WM_COPYDATA if the data is in lParam (msg == original call. WM_COPYDATA & amp; amp; & amp; amp; amp; WPParam == original call. H.F.F.D.A.A.A.T.T.) {Copdatatadata Data = (Copdatatact) Marshall.traighter structure (LPAMM, typef (COPIDATTCT)); StateTextBox Appendex (Data. LPDT + Enterprise. Newline); // Check for connection if (data.lpData.IndexOf ("CONVITATUS ONLINE") & gt; -1) connect button. I.e. enabled = false; // Check for Call IsCallInProgress (data.lpData); Handled = true; New Interrupt Return (1); } Return IntPtr.Zero; }   
 I've seen people  like to use this kind of code above in WPF 
  protected override void OnSourceInitialized (EventArgs e) {base.OnSourceInitialized ( E); // WndProc HwndSource Source Attached = Presentation Source. FrameVisual (this) as HwndSource; Source.AddHook (WndProc); }    
 
 
 You can use the method.  
  [SecurityPermission (SecurityAction.LinkDemand, flags = SecurityPermissionFlag.UnmanagedCode)] public class TestMessageFilter: IMessageFilter {public bool PreFilterMessage (ref Message m) {// blocks all messages associated with the left mouse button. If (m.msg> = 513 & amp; amp; m.sg & lt; = 515) {Console.WriteLine ("Message Processing:" + m.msg); Back true; } return false; }}

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
