I may be going over the obvious here but:

xtwArticles = new XmlTextWriter ("test.xml", 0);
xtwArticles->Formatting = Formatting::Indented;

That is the C++ version that I am using and the XML comes out nicely formatted. For the C# version just replace the 0 with System.Text.Encoding.UTF8

Comes out of where ? I have a complete XML file which is not formatted, coming out of an XmlDocument. I tried passing it into an XmlTextWriter as a string and pulling out the result, but it was just a blob of unformatted XML, just the way it started.

I want to take
<xml><node><subnode>sdjkfsl<node><node2>sdfsf
for example, which I have as a string, and pass it into something that formats it. I've actually written my own function which does this, but I'd prefer to use the one provided if I can make it work.

*sigh* I am not devout anything. Yes I have up until a short time ago mainly been using VB, though that is really VBScript and that was a limitation of ASP and so was forced.

However VB has always been up to my needs and it is good at what it does. Right tool for the right job.

As for venturing into C++: I am entering the Visual C++.NET competition Big Grin | :-D

I thought it would be a fun thing to learn and also as a way to prove that a VB coder can do C++.

That "C++ version that I am using" bit is because my MC++ class writes and reads some XML.

I like knowing a little bit about everything, makes me dangerous (you know, the saying "A little knowledge is a dangerous thing" Big Grin | :-D

Hi,

If you look at an article about XmlSerializer submitted end last week, you should get an better idea too. Smile | :)

Here some code i have used:

System.Xml.XmlTextWriter xmlwriter = new XmlTextWriter(filename, System.Text.Encoding.ASCII);
xmlwriter.Formatting = Formatting.Indented;
xmlwriter.WriteStartDocument();

xmlwriter.WriteDocType("Options", null , null, null);

xmlwriter.WriteComment("MYrc Option File. Edit at own risk!");
xmlwriter.WriteStartElement("Options"); //root element

PropertyInfo[] props = this.GetType().GetProperties();

foreach (PropertyInfo prop in props)
{
    xmlwriter.WriteStartElement(prop.Name);
    object da = prop.GetValue(this, null);
    xmlwriter.WriteAttributeString("Type", prop.PropertyType.ToString());
    if (da != null) xmlwriter.WriteAttributeString("Value",da.ToString());
    else xmlwriter.WriteAttributeString("value", "null");

    xmlwriter.WriteEndElement();
}
xmlwriter.WriteEndElement();
xmlwriter.WriteEndDocument();
xmlwriter.Flush();
xmlwriter.Close();

This is for an OptionGrid class in trying to get going, but I have had no success with non primitive types Frown | :(

, but it works well with primatives Smile | :)

Hope this helps.

Thanks - I had seen that the writer could be used to write XM a node at a time, but I already have the XML as a string, and I want to pass it in one go. A method is provided to do this, but I tried it and it did not format the XML for me, it just passed it back. I set the Formatting to be Formatting.Indented before I passed the string in.

Hi, all
I try to create a wizard for vs.net when new project or file, when I test my wizard, vs.net always pops up a dialog "Could not run the xxx wizard".

firt part is my dll source:

using System;<br />
using System.Windows.Forms;<br />
using EnvDTE;<br />
<br />
namespace MyVSWizard<br />
{<br />
	/// <summary><br />
	/// Summary description for Wizard.<br />
	/// </summary><br />
	public class Wizard : Object, IDTWizard<br />
	{<br />
		public Wizard()<br />
		{<br />
			//<br />
			// TODO: Add constructor logic here<br />
			//<br />
		}<br />
		public void Execute(<br />
			object Application,<br />
			int hwndOwner,<br />
			ref object[] ContextParams,<br />
			ref object[] CustomParams,<br />
			ref wizardResult retval<br />
			)<br />
		{<br />
			MessageBox.Show("Hello world");<br />
		}<br />
	}<br />
}

then I use "regasm /codebase" to register the dll as a com and get the clsid ={34470340-B2D6-39A4-AFDA-A53A13D04DF7}.

then my .vsz file

VSWizard 7.0<br />
Wizard={34470340-B2D6-39A4-AFDA-A53A13D04DF7}

then my clause in .vsdir file

MyWizard.vsz|{34470340-B2D6-39A4-AFDA-A53A13D04DF7}|0|270|My First Wizard|{34470340-B2D6-39A4-AFDA-A53A13D04DF7}|0|0|MyClass.cs

Inheriting a Windows Form as a User Control

Anyone have any idea if it is possible to take an existing Windows Form (filled with working controls) and have it inheret to a User Control?

Otherwise I am going to have to copy over everything from the Windows Form to a new User Control, which is a chore Smile | :)

Hi Paul

How about just changing the inheritance part from Form to UserControl and remove the Main method?

There mite be one or 2 form specific Properties that needs to be removed if the compiler complain, also compile as class library, and then just add the dll to the toolbox, and walla you have a UserControl.

Hope this helps Smile | :)

Llewellyn, you are my personal Savouir and God Programmer Of The Day.

I am still laughing at how that actually worked, and worked like a bomb! The difference between a Windows Form and a User Control is a couple lines of code (no maximise button etc.) and one reference!

I was actually trying to get the Windows Form hosted as a Visual Studio.NET ToolWindow Add-In. But when a Windows Form was hosted that way, it went berserk. However I had successfully hosted a User Control before and was trying to wrap the Windows Form up as a User Control.

Instead I have taken your advice and modified it slightly; The actual Windows Form is now defined as a User Control: public class frmMain : System.Windows.Forms.UserControl

And that is then hosted by VS.NET.

No having to port all those controls and functions to a User Control.

thanks man, you get big kudos today Big Grin | :-D

Thanx you made a blue monday a bit less blue Smile | :)

Basically everything in System.Windows.Forms inherites from Control. I only picked this up the other day. You could also try just removing the main method and add a form by casting to Control (havent tried it).

I have been using Anakrino to have a look around inside the System.Windows.Forms.DataColumnTextBoxColumn class and there is something I do not understand about the decompiles.

I quite often see the line goto i-1; but there is never a matching label to go with it (the Edit method being an example). Also Visual Studio will not compile a goto statement in that form, it chokes on the -1 part.

Can anyone give me a hint as to where it is going to jump to with a lable of i-1?

Thanks

Stephen.

I've seen that with anakrino as well. The best way I've found to figure out what's going on is to open up the ILDisassembler tool in the sdk and try to find that line. Of course, you'll have to know how to fumble your way thru IL a bit to do this.

Raising events in C# ASP.NET app.

Naresh Karamchetty28-Jul-02 14:24

28-Jul-02 14:24

I am writing an ASP.NET application where I have an invisible button. What I want to do is to programmatically raise the button's "OnClick" event so that a client-side function that is attached to the button will be called. Is there a way to manually raise the event? Trying to call "OnClick" directly does not work as the compiler gives an error. I know that VB.NET has a RaiseEvent keyword, but no apparently no such counterpart exists in C#. So, is there a way to manually raise events in ASP.NET controls?

Signing an assembly

28-Jul-02 11:53

Hey all - I've been trying to get this to work all morning. I have a .cs file that looks like the following:

<br />
using System;<br />
[assembly: AssemblyKeyFile(@".\MyPair.snk")]<br />
namespace Seruyange.David.Examples{<br />
    public class StrongName{<br />
        public void test(){<br />
            // just a test method<br />
            Console.WriteLine("This is a test...");<br />
        }<br />
        public static void Main(){<br />
            // the main, for perfunctory sake<br />
            Console.WriteLine("Here is main");<br />
        }<br />
    }<br />
}<br />

I generated the .snk file okay. I try compiling with the following:
<monospace>
csc /out:test.exe TestAssembly.cs

But I always get the error:
Type or namespace name 'AssemblyKeyFile' could not be found (are you missing a using directive or assembly reference)

Can anyone help? I'm just trying to generate a strong name.

How to create a drag box?

albean28-Jul-02 4:50

28-Jul-02 4:50

Hi,

I would like to create a drag box on a form. The behavior that I'm talking about is what you see in the Form Designer of the IDE when you click and hold down the mouse button on a form (but not on a control that you placed) and drag the mouse. A dashed box is drawn while you hold down mouse. Could somebody tell me where I should be looking to begin coding something like this? (It would be cool if there were an example but anything would do.)

Thanks!

ListBox linked to Database

laphijia28-Jul-02 4:34

laphijia

28-Jul-02 4:34

I have a database that contains 2 tables.
The first called Users contains username and password
the second called PhoneNumbers contains a primary key called PhoneNumberID, a User column and a column with the telephone numbers of the users, that can be 0, 1 or more.

There is a relationship one-two-many between the username in the Users table and the username in the PhoneNumbers table.

Now I want to make an application that displays the phone numbers of a given user and allows to add or delete new numbers.

I thought that the best method is to use a listBox, a texBox and two buttons, add and remove.
The user loads the data from the database, populate the listBox, selectt a number and clicks delete, and the number is deleted. Write a number in the textBox and clicks add and the number is added.

I make this through an XML Web Service.

I have a method that takes username and password, and returns a DataSet to the clien.
Than i use foreach to add all the returned phone numbers to the listbox.

Now THE QUESTION:
How I manage the update?
If a user added a phone number, the update should add a row to the database, if delete delete the corresponding row.

When the user clicks the update button, the code should,
check all the items actually in the listbox, determine if it was added, or know if some of the previously held was deleted.

HOW I ACCOMPLISH THIS?

And after this, how I create a link with the rows in the database, since the listbox, contains only the phone number value, but no primary key of the PhoneNumbers table?

An help is greatly apreciated.
