Actually, you had one right (PAL, and thanks for correcting me on that) but the 29.97 fps I am sure of. See http://www.microcinema.com/index/ntsc[^], for example.

It would, but that would make the fade more 'realistic'. Also call Application.DoEvents() after each call, so the UI seem to 'respond'.

You could handle this using a timer in your form. Handle its elapsed event and make gradual changes with each tick, stopping the counter when the opacity reached its min or max. I have done this and it produces no flicker.

Side TabControl

I'm looking for a .NET control that implements a "sideways" tab strip or tab control. Basically, like the tab control in Windows Forms, but on the side of the form rather than at the top or bottom. Ideally, text orientation and colors, fonts, styles, etc. should be flexibile.

Anyone know of any such control (free or commercial)?

The TabControl in the SharpLibrary is very flexible. It might be what you are looking for.

Send the proper command to authorize the client, just as the server indicates. If you say EHLO instead of HELO to the SMTP server when you connect, it gives you a list of support authentication modes. You must support one of those and authorize yourself as requested.

Hi:

You can check out http://www.systemwebmail.com/ for how going about authenticating to a SMTP server from a .NET application.

Perhaps you can have a small console app and get the idea behind it. Is'nt it?

Hi..

I have a listview control on a form..For this i added 3 ColumnHeader's..Later i added few items to this class..When i try to resize these columnheaders all the items in the listview are also getting resized properly..

But my question is when i try to resize any columnheader in the listview control, i want an event to be raised in my code..so are there any default listview events which are raised for this..if not how can i do this..

Thanks in advance..

Office Automation - problem with Find object

Matt Casto4-Jun-04 6:05

Matt Casto

4-Jun-04 6:05

I'm trying to get office automation working, and most things work except working with the Find object. For some reason, every time I try to access the Find object (both through Selection or Range) I find that the Find object is a null reference. If I try to add a watch to my Document and debug, when I expand the Selection then the Find object, my debugger crashes. I am running Office 2000. Trying similar code in VB.NET yields similar results.

The following is a simple Console app that I created to test this. It only requires that the "C:\TestFindReplace\TestDoc.doc" is a valid path with a word doc that contains the text ":FULLNAME:" somewhere. Of course, you can change the filename and path to whatever if you want to test this code. Also, you will need to add a reference to the Microsoft Word 9.0 COM object.

<br />
[STAThread] static void Main(string[] args)<br />
{<br />
  Console.Write("Enter the person's name: ");<br />
  string fullName = Console.ReadLine();<br />
  Console.WriteLine();<br />
  FindReplace(fullName);<br />
}<br />
static private void FindReplace(string fullName)<br />
{<br />
  object oFileName = @"C:\TestFindReplace\TestDoc.doc";<br />
  object oNewFileName = @"C:\TestFindReplace\" + fullName + ".doc";<br />
  object oFalse = false;<br />
  object oMissing = Type.Missing;<br />
  object oReplaceAll = Word.WdReplace.wdReplaceAll;<br />
<br />
  Word.Application WordApp = new Word.ApplicationClass();<br />
  Word.Document myDoc = WordApp.Documents.Open(ref oFileName,<br />
    ref oMissing, ref oFalse, ref oMissing, ref oMissing,<br />
    ref oMissing, ref oMissing, ref oMissing, ref oMissing,<br />
    ref oMissing, ref oMissing, ref oFalse);<br />
  try<br />
  {<br />
    myDoc.Application.Selection.Find.Text = ":FULLNAME:";<br />
    myDoc.Application.Selection.Find.Replacement.Text = fullName; <br />
    myDoc.Application.Selection.Find.Execute(ref oMissing,<br />
      ref oMissing, ref oMissing, ref oMissing,<br />
      ref oMissing, ref oMissing, ref oMissing,<br />
      ref oMissing, ref oMissing, ref oMissing,<br />
      ref oReplaceAll, ref oMissing, ref oMissing,<br />
      ref oMissing, ref oMissing);<br />
    myDoc.SaveAs(ref oNewFileName, ref oMissing, ref oMissing, ref oMissing,<br />
      ref oMissing, ref oMissing, ref oMissing, ref oMissing,<br />
      ref oMissing, ref oMissing, ref oMissing);<br />
  }<br />
  finally<br />
  {<br />
    WordApp.Quit(ref oMissing, ref oMissing, ref oMissing);<br />
  }<br />
}<br />

Is anyone getting behavior like this? Does this code work for anyone else?

That's because the Find object isn't part of a Document object (at leat in Word 2003). It should look more like this:

object oFileName = @"C:\TestFindReplace\TestDoc.doc";
object oNewFileName = @"C:\TestFindReplace\" + fullName + ".doc";
object oFalse = false;
object oMissing = Type.Missing;
object oReplaceAll = Word.WdReplace.wdReplaceAll;

Word.Application WordApp = New Word.ApplicationClass();
Word.Document myDoc = WordApp.Documents.Open(ref oFileName,
    ref oMissing, ref oFalse, ref oMissing, ref oMissing,
    ref oMissing, ref oMissing, ref oMissing, ref oMissing,
    ref oMissing, ref oMissing, ref oFalse);
try
{
    Word.Find fnd = WordApp.Selection.Find;
    fnd.Text = ":FULLNAME:";
    fnd.Replacement.Text = fullName; 
    fnd.Execute(ref oMissing,
        ref oMissing, ref oMissing, ref oMissing,
        ref oMissing, ref oMissing, ref oMissing,
        ref oMissing, ref oMissing, ref oMissing,
        ref oReplaceAll, ref oMissing, ref oMissing,
        ref oMissing, ref oMissing);

Unfortunately, I get the same error. I'm using Office 2000 and I suspect that it might be a problem with this version of office. I had a co-worker with the same PC configuration run this app and he got the same error.

I'm leaving for two weeks of vacation tomorrow, so I'll have to put this issue on hold until I'm back. Thanks for your help!

RegisterClass equivalent

sjhart4-Jun-04 5:20

Hi
We have a system which is written in C++/MFC but I have just written a support tool in C#/.NET.

This is all new to me and we need to be able to show an already running copy of the app from the C++ system.

We were going to use FindWindow() from MFC, but would prefer to set the class name rather than just rely on the window caption. However I cannot find any equivalent to RegisterClass() in .NET and if I set CreateParams.className the .NET app blows up with an 'Invalid Windows class name' exception.

Does anyone know how to set/register the class name so we can uniquely identify our support app?

Every control is already given a class name. Use Spy++ from the Platform SDK (installed with Visual Studio in default installs) to determine what that class name is.

Thanks for the quick reply.

I have tried Spy++, but every .NET app I have written seems to have the following class name "WindowsForms10.Window.8.app1".

Is it possible to override the automatically generated name or supply some string which will be used as part of the automatically generated name?

Re: RegisterClass equivalent

Heath Stewart4-Jun-04 5:54

If you examine the child windows, you might notice a pattern: WindowsForms10.ClassName[.8].appN. You can change the class name for a window but you have to register it first, which means you must P/Invoke RegisterClass, which of course means you have to define the WNDCLASS struct in managed code (with proper byte alignment and marshaling). You could then use this window class in your override to CreateParams.

[DllImport("user32.dll")]
private static extern ushort RegisterClass(ref WNDCLASS lpwcx);
 
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Auto)]
private struct WNDCLASS
{
  public UIntPtr style;
  public WndProc lpfnWndProc;
  public IntPtr cbClsExtra;
  public IntPtr cbWndExtra;
  public IntPtr hInstance;
  public IntPtr hIcon;
  public IntPtr hCursor;
  public IntPtr hbrBackground;
  public string lpszMenuName;
  public string lpszClassName;
}
 
private delegate IntPtr WndProc(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);

Of course, you must provide it with all the data necessary. The WndProc delegate should point to Control.WndProc, and the other data you can marshal from various properties of the Form or any other Control derivative. Use the Marshal class for assistance if necessary.

Once you've done that, the final window class would most likely be WindowsForms10.YourClassName.appN.

Another option you could consider is using global memory.

a syntax question?

BillAnton4-Jun-04 5:14

Hi to all,

I am trying to change a boolean field in an Access database table.

<code>
DataRow[] selectRows = dscurr1.Tables["currlist"].Select("curr='true'");
foreach (DataRow myRow in selectRows)
{
idx = Convert.ToInt32(myRow["notableID"]);
}
</code>

This locates the index to the row that has the only boolean True row in this small table, but now I need to change it to False and realize I need to use an indexer to the DataRow but am lost as to how it should be laid out syntacically.

Regards,
Bill Antonacchio

Just use myRow["curr"] = false. If this isn't what you're asking about, please rephrase your question.

You're right - it is simple: simply create a new OleDbCommand around an UPDATE statement, or if you just change it in the DataSet like I showed you before, pass it back to an OleDbDataAdapter using the Update method, which requires that you have the OleDbDataAdapter.UpdateCommand assigned (plus InsertCommand and/or DeleteCommand if you want to support INSERT and DELETE statements as well). The SelectCommand is required.
