If you have questions or comments about an article here on CodeProject you need to ask in the message board at the bottom of the article - that's what it's there for.
If you are new to C#, I suggest you read about the Visual C# Language[^] and browse over the table of contents for the Class Library[^].
There's many books about C# as well. You can find many Microsoft-approved books at http://www.microsoft.com/mspress[^], and many more on Amazon[^].
This forum is for specific questions regarding C#.

Is there any possibility to return windows form a remote application to client application, in distributed application environment. I tried with .NET Remoting (Hosting server in Windows Service and IIS) as well as through Web Service. But none of them worked.
|
|
|
|
|
Edit:
No, it's not. Even if it was, you'll end up displaying the form in the server process, not the client process - which I discovered not too long ago.
This is all totally in contradiction to what I had originally said. Whooops.

I have build a Win Application using C# that interact with an embedded Web Browser Control. I need to highlight text that user searches for in the loaded browser document. Kind of like the Windows Xp help center. When you look for something, the help article is loaded and the text you are searching for is highlighted.

Add a reference to the Microsoft.mshtml.dll assembly that should've been installed with VS.NET. If you don't see it in your list of references, then in the Add Reference dialog click the COM tab and find the "Microsoft HTML Object Library" and add that. VS.NET will automatically create an interop assembly (RCW, or Runtime Callable Wrapper) for you and reference that.
To begin, when your document is loaded cast AxWebBrowser.Document to IHTMLDocument2 (add the Microsoft.mshtml namespace to your using clauses, BTW). Now you have a reference to the HTML DOM. From there you'd do what you'd do in HTML to highlight text, only you're doing it using the actual interfaces instead of how you'd do it in JavaScript/JScript or VBScript. The script uses the HTML DOM - the very one you've referenced, so what you get is the same (and more so).
Do that, cast IHTMLDocument2.body to IHTMLBodyElement and call createTextRange to get an IHTMLTxtRange. With that keep calling findText until it returns false. Each time that string is found do something like this:
range.htmlText = @"<span style=""color:white;background-color:darkblue;"">" + range.htmlText + @"</span>";

Thank you for your help. The documents that I load in the browser are xml files and are in Arabic (right to left). I have tried the method you described above. Eventhough it worked well, I had a little bit of formatting problems. I decided to search xml files themselves, and format the matching strings using xslt file.
Anyway, thank you for your help. It set me on the right track.

how to add it to richtextbox?
|
|
|
|
|
You can't. Both are controls, and the RichTextBox is not a container controls. You could always try to site (that is, manually position the LinkLabel control as the RichTextBox is scrolled) but that can be difficult.
A better question is why? Just set RichTextBox.DetectUrls to true. Whenever a URL using a recognized protocol scheme is entered into the text, it is a URL. Then add a handler for the RichTextBox.LinkClicked event and do what you would've done in a LinkLabel.LinkClicked event handler.
The protocols schemes that are automatically detected - from the Platform SDK - are:
http:
file:
mailto:
ftp:
https:
gopher:
nntp:
prospero:
telnet:
news:
wais:
outlook:

hi
i known that but my links are not url ,they are say a name such "X".
what should i do plz?
|
|

The Rich Edit common control - which the RichTextBox encapsulates - does not support extensible URL detection, unfortunately, but you can implement this yourself.
When the text changes scan behind the caret (get the SelectionStart property) and see if its text you want to recognize as a "URL". Use the SelectionColor and SelectionFont to highlight and underline the font.
If you want to use the same font style that the RichTextBox is using, use the Microsoft.Win32.RegistryKey class to read appropriate values from HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Settings.
Handle the Click event, get the SelectionStart again, determine which text was clicked and, if it's a "link", perform whatever action is appropriate.

The underlying RichEdit control has a way to mark an arbitrary character range as link, even if it's not starting with one of the recognized protocols.
Basically, you'll have to use interop to send the message EM_SETCHARFORMAT to the RichTextBox and specify CFE_LINK as effect.
The message and parameters are described on MSDN, you can look up the documentation there.
You might want to take a look at this article[^] (follow the section "Adding Formatting to the New Class") on how to set the character format in a RichTextBox. The code there can be easily modified to allow for setting the Link style as well.
I guess I'll write an article about this in the near future because this topic comes up from time to time...

mav

Hi all,
In VC++, in CRichEditControl class have a method naming 'LineScroll'. This method is used to scroll HScroll to any line. Would you tell me method in C# that similar LineScroll method of CRichEditControl class in VC++.
Thank you very much,
|

You could implement a similar method using P/Invoke:
public class ExtendedRichTextBox : RichTextBox
{
[DllImport("user32.dll")]
static extern IntPtr SendMessage(IntPtr hWnd, uint msg,
IntPtr wParam, IntPtr lParam);
const uint EM_LINESCOLL 0x00B6;
public void ScrollToLine(int line)
{
IntPtr lParam = new IntPtr(line);
SendMessage(Handle, EM_LINESCOLL , IntPtr.Zero, lParam);
}
}This will not extend past the last line. Read in the Platform SDK about the EM_LINESCROLL message for more information.

Hi all,
What is the best design of data schema for a custom form ? (i.e. the user can add more fields to a form according to his own need) Any reference for this kind of data schema design ?
Thanks
|
|
|
|
|
What you ask is pretty ambiquous. Are you trying to define a form using an XML file? That's been done over and over. Look at XAML from Microsoft (.NET will support this in the future, and Microsoft has announced plans to support this down to Windows 2000, IIRC - not just "Longhorn") or Myxaml[^] from our very own Marc Clifton.
Or is your data schema a DataSet that will be used to update a database, and you want to design a Form to fill fields based on what is in the DataSet schema?
I can think of many other things you might mean, too, so please explain exactly what you're trying to do.

Thanks for your reply.
I mean the relational database table schema. Consider the database schema for a custom form which is extensible (the user can put more fields on the form).
e.g. for the fields in a form
Table schema :
Name string
Address String
City String
Then the user add more fields later :
Name string
Address String
City String
Country String
phoneNo int
faxNo int
So what should be the design of the relational database schema that
can allow the user to extend arbitrarily ?
Thanks

You can either do it like Microsoft SharePoint and store the data in a single ntext field, or use an many-to-many relationship to define the columns and contain their data:
Column
------
ID: int (key)
Name: nvarchar(64) (w/ unique constraint (not key; too slow for text))
Type: nvarchar(256)
Description: nvarchar(256)
Values
------
ColumnID: int (FK to Column.ID)
DataID: int (FK to Data.ID)
Data
----
ID: int (key)
Value: ntext (serialized value; easy to represent data across platforms) Something along those lines works and I've used it before.

I want to change ShortDate Format from System Regional setting.At the first time i asked,someone replied me to use System.Globlization .but i can't use it. Pls Advise me for that Problem.
|
|
|
|

Not an answer but why can't you use System.Globalisation? I think you will be in for a world of hurt if you don't use the built-in namespace. Modifying it yourself will mean doing it at every point your app displays or inputs a date.
