Yes or even sections. That's what all this nonsense about Web Parts and others are about. You can divide your page into sections with say a DIV element as a parent to all the content. Then you can transform XML/XSLT into the new content for that DIV and update just that part of the page. It's nothing new, it's all been around since like IE 4 I believe.

A long time ago I used XML Data Islands to contain the data for a very dynamic browser based application. This is essentially what you are doing. Have you thought about AJAX or script callbacks to get chunks of rather than the whole thing?

The way I'm doing this is sort-of like AJAX without using the JScript XML HTTP GET request, but a custom API function call built into my API. The JScript can call for new data when it needs it or the user can invoke it to update/refresh manually.
As I posted in the example code I didn't add all of the XML phrasing stuff, but a simple load and dump the XML. For the example it could have been just as easy to use File.readalllines on String.Join them it together to send the string.
string[] XmlLines = File.ReadAllLines("C:\randomXMLfile.xml");
string XmlString = String.Join("\n", XmlLines);
But then where isn't an XML document or node, which was the original point of my question. Anyway enough of my clarification rant, the data is already in chunks and my example doesn't show it.

To clarify, you are have coded you own version of an existing framework. Now then, what was the question?

I didn't recode and existing framework to my own version. AJAX requires a web server to serve an XML file. You open an JScript XML HTTP GET request and call an URL running a server side script (ASP.NET, PHP, and so on) that returns XML via a text string.
I'm using a WinForm C# application with a webbrowser control that is running a local JScript page to dynamically request and display data XML returned to it.
The page is setup as a JScript page so it is possible to easily change the interface (skinning, overall functionality, and so forth) without recompiling the application. The C# program just collects and then XML formats the data. This data could be posted to a webpage or just saved as XML on the users PC. The webbrowser control + JScript page allows the user to view it as it is being collected, or to view data that isn't saved (maybe logging is off) as it comes in.

My question was as stated in my orgianl post.
Is there a way to pass an System.Xml object to JScript via com using a [ComVisible(true)] class set to the WebBrowser.ObjectForScripting property of a web browser control?

It is possible to serve web pages, or handle http requests without a webserver.
It seems to me as though you are making this more complicated than it needs to be. Use xslt to transform you xml into the appropriate html to be displayed in a webbrowser control.
Insert the XML into a XML data island via the HTML DOM.

I know what you mean but using the <xml src=""> data island makes it harder to port over to Mono.Mozilla.WebBrowser.dll for a gecko based browser control.

It is easier to give advice and answers when relevant information is stated up front. If this is a Windows app, you are guaranteed to have IE on the machine, why bother with trying to support others browser controls. I'm sure your project has a timeline and budget, does it including trying to develop something to support all possible combinations of technology?
Good luck

Hi guys. I have the below code but am having problems with compiling the code. I get the following error when compiling the code. I know where the error is but do not know how to fix it. Can somebody please advise?
The error message is as follows:
"Operator '==' cannot be applied to operands of type 'method group' and 'bool'"
private void btnCancel_Click(object sender, EventArgs e)
{
this.Close();
this.Dispose();
}
OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=W:\CS Call Info\MobEmail.mdb");
OleDbCommand cmd;
private void btnLogon_Click(object sender, EventArgs e)
{
string sql = "SELECT UserName,Password FROM Users WHERE UserName = '"
+ txtboxUserName.Text + "' AND Password = '" + txtboxPassword.Text + "'";
OleDbCommand cmd = new OleDbCommand(sql, conn);
OleDbDataReader dr = cmd.ExecuteReader();
try
{
conn.Open();
}
catch (InvalidOperationException ex)
{
MessageBox.Show(ex.Message.ToString());
}
try
{
if (dr.Read == false)
{
MessageBox.Show("Invalid Username And Or Password Supplied", "Logon Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
else
{
this.DialogResult = DialogResult.OK;
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
if (conn.State != ConnectionState.Closed)
{
conn.Close();
}

Brilliant. Understood and rectified. It now works. Thanks a mill mate. Just needed somebody to point me in the right direction. Below the code changed and it works fine.
private void btnLogon_Click(object sender, EventArgs e)
{
string sql = "SELECT UserName,Password FROM Users WHERE UserName = '"
+ txtboxUserName.Text + "' AND Password = '" + txtboxPassword.Text + "'";
OleDbCommand cmd = new OleDbCommand(sql, conn);
conn.Open();
OleDbDataReader dr = cmd.ExecuteReader();
try
{
}
catch (InvalidOperationException ex)
{
MessageBox.Show(ex.Message.ToString());
}
try
{
while (dr.Read() == true)
{
this.DialogResult = DialogResult.OK;
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
if (conn.State != ConnectionState.Closed)
{
conn.Close();
}
}

1. Read is a method so it needs brackets.
2. Your code is open for sql injection attacks. This article will help you to avoid them SQL Injection Attacks and Some Tips on How to Prevent Them[^]
4. You should open connection first in order to invoke ExecuteReader()
3. Use finally block to close connection.

I am unable to figure out how to simulate a SHIFT+MOUSE_RIGHT_CLICK, I tried several samples without any luck, here is some of the code I am using to try and get it to work...
<br />
[DllImport("USER32.DLL")]<br />
public static extern int SendMessage(IntPtr hwnd, int<br />
msg, int character, int count);<br />
<br />
[Flags]<br />
public enum MouseEventFlags<br />
{<br />
LEFTDOWN = 0x00000002,<br />
LEFTUP = 0x00000004,<br />
MIDDLEDOWN = 0x00000020,<br />
MIDDLEUP = 0x00000040,<br />
MOVE = 0x00000001,<br />
ABSOLUTE = 0x00008000,<br />
RIGHTDOWN = 0x00000008,<br />
RIGHTUP = 0x00000010<br />
} <br />
<br />
--- THE ACTUAL CODE ---<br />
<br />
SetCursorPos(ox + xx, oy + yy);<br />
<br />
win32.SendMessage(phwnd, 0x0100, 0xA0, 0);
<br />
mouse_event((uint)MouseEventFlags.RIGHTDOWN, 0, 0, 0, 0);<br />
mouse_event((uint)MouseEventFlags.RIGHTUP, 0, 0, 0, 0);<br />
<br />
win32.SendMessage(phwnd, 0x0101, 0xA0, 1);
<br />
Looking for help, suggestions or a "Hey, your doing this wrong you tool!"
Best,
 Mike

This won't be a very helpful reply, I'm sorry.
I'm curious though - why do you want to simulate a Shift+Mouse_Right_Click?
|
|
|
|
|
Edit: Oops. I figured you wanted to detect shift-right mouse click behavior, but I see you want to simulate that. No idea there really...
Standards are great! Everybody should have one!

Might be a mistake during your copy-pate of the example code but it looks like you're missing
[DllImport("User32.dll")]
static extern void mouse_event(MouseFlags dwFlags, int dx, int dy, int dwData, UIntPtr dwExtraInfo);
|
|

My guess is that you are missing the click. The reason why is that the coordinates sent to the mouse event MUST match the coordinates that the mouse is actually at. If not, windows ignores the event altogether. I would open Spy++ and make sure that all your messages are being sent identically as when you do it manually. I also didn't check your SendMessage syntax/data, so you may have done that wrong as well. If you fix the mouse_event problem and it still doesn't work, let me know and I will check the other. Good luck,
Sounds like somebody's got a case of the Mondays

Just checked it out, the mouse click event works, my problem is that the shift key is not being depressed.
Does my shift code look ok?
|
|
|
|

What happens if you just send the SHIFT key (0x10)? I also wonder if, since you are sending a specific shift key, if you have to set bit 24 on the lparam sent with SendMessage. In the past I have also had instances when I had to use PostMessage for an application to receive the keystroke. If I were you I would go through the following progression:
1. Try using SendMessage (up + down) for something simple (like an 'a' 0x41).
2. Try using PostMessage (up + down) for something simple
3. Try using keybd_event (up + down) for something simple
If none of the above messages were received by your target application (and the last win32 error is not from your calls to the methods), then post your results so I can help some more. Otherwise, continue using the message type (Send, Post, or event) that worked from steps 1-3:
4. Modify your messages to send the Shift key (if it doesn't work, try sending the left or right specific shift keys; if you still get nothing, use Spy++ to see EXACTLY what each parameter is being set to, and mimick exactly those params)
After you complete these steps, you should be able to get your code working. Here is a reference for WM_KEYDOWN[^] if you need it. Let me know if this helps,

Hi
I search an ORM tool for C# (working with ADO.NET) which supports obfuscation.
I tried NHibernate, but it does not support obfuscation.
Anyone knows one ?
Thanks !
|
|
|
|
|
A large portion of ORM tools use reflection - so obviously if you start obfuscating property names then things will break.
First time I've heard someone ask this so I have no idea how Diamond Binding stacks up (and I have to admit I'm curious). In an ideal world the obfuscator would pick up all string references to types in config and sort it out.
Give it a try and let me know how it goes
