Create an XmlDocument object and load the xml file into it. Add nodes to it and save it.

You have all the documentation at MSDN Library[^]. Search for "XmlDocument class".
The DocumentElement property is a collection of XmlNode objects that is the nodes in the root element. You can use the CreateNode method to create a node, then add it to the collection.

Hi ! All,
I want to execute a dialog based application developed in VC++ in Windows CE (Platform Builder 4.2). I have imported all the dialog boxes successfully.
My application is compiling in Platform Builder without errors but not executing.
In VC++ we use Domodal() for Dialog boxes. I suspect that this is a problem when executed on Platform Builder.
Can anyone suggest me any ideas on the same lines or an equivalent function for Dialog boxes in Platform Builder 4.2...
Awaiting your reply.
Regards,
Sameer

Hi,
I apologize in advance if this is not the right place to ask.
I've created my own BindingNavigator control, inheriting from the .NET one, and I have created my own DataGridView in the same way.
I've also be able to associate my DataGridView with my DataSources so that when I drag&drop a DataSource onto a form my custom DataGridView is created.
The problem is that along with my DataGridView the Default .NET BindingNavigator is created. I need MY Custom BindingNavigator to be created and associated to my Custom DataGridView automatically, so I don't have to delete the Default B.N., drag and drop my Custom B.N. and associated with my custom DataGridView.
Is there any way to do that?
I really appreciate any help in advance.
Thanx.
FJ

Hi,
i'v been looking everywhere for a solution to the following problem. Im basically looping through all the directories and files in my project, and in each loop i retrieve the filename of the aspx file. Now what i want to do is create a temporary object tempPage of type Page that refers to this aspx page. How do i do this? Is there anyway i can load a Page object from just it's filename?

I'm having trouble with the Graphics class. I developed a class and gave it a method called Draw which takes a Graphics class as an input then draws itself to this. Fairly obvious stuff I thought.
In the parent forms onpaint call I loop through all the instances of my class calling the Draw method and passing it the eventArgs.Graphics object but for some reason it only displays the last class in the array. This is my current code. I even tried taking the contents of Draw(Graphics g) and putting it in the for loop but even this didnt help.What am I doing wrong? Any help would be greatly appreciated...
private void canvas_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
int i;
e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
for(i=0;i<n;i++)
{
pArray[i].Draw(e.Graphics);
}
if(adding)
{
tempParticle.Draw(e.Graphics);
}
}

What kind of drawing are you doing in the class? Are you drawing the objects on top of each other?
Where do you set the value of the "n" variable?
Have you verified that you actually have all the objects in the array?

Don't worry fixed it. It wasn't actually a problem with the Draw function, it was how I was assigning values to the array. I was using;
pArray[i] = tempParticle;
But with using;
pArray[i] = new Particle(...)
seems to work fine. Thanks anyway.

I see. So you populated the same object over and over, and ended up with an array full of references to the same object.

Yep, pretty stupid I know  , but then I have only been using C# for a few days.

Hi All,
Can anyone tell me how to replace the default "Property value is not valid" message that is displayed if an exception is thrown when changing a property on the PropertyGrid?
I am using the standard PropertyGrid in .NET 2.0 within my winforms app. The PropertyGrid is bound to my custom data objects. If an exception is thrown (eg, "This field must not be left empty"), the default "Property value is not valid" message box is displayed, with my exception message in the Details section.
It is a requirement of the app to display a more friendly message to the user. Is there any way I can replace the default dialog box?
Thanks
Nick

Hi,
I want to override the open button event in Word / Excel. I have created an addin. Now I need the index of Open button. Here is the code that i am using.
object oActiveExplorer oActiveExplorer=
applicationObject.GetType().InvokeMember("ActiveExplorer",BindingFlags.GetPr
operty,null,applicationObject,null);
CommandBars objCommandBars=
(CommandBars)oActiveExplorer.GetType().InvokeMember("CommandBars",BindingFla
gs.GetProperty,null,oActiveExplorer,null);
objToolBar = objCommandBars["File"];
CommandBarControl objCommandBarCtrl = objToolBar.Controls["FileOpen"];
CommandBarControl objCommandBarCtrl1 = objToolBar.Controls["Open"];
I have tried FileOpen and Open both but it is not correct. It is throwing an
exception.
Can anybody please help me.
Thanks

Hi dear friends.
I've ported a native (Unmanaged) C++ DLL to managed and used in .Net 2003.
Now I'm going to use this ported DLL it in .Net 2005. I change the compiler option /clr to /clr:oldSyntax and compile with no error.
But at run-time I get a exception when I want to use the DLL in a C# client.
The error message is:
MyDLL.dll is attempting managed execution inside OS loader lock. Do not attempt to run managed code inside a DLLMain...
Anyone can help me?

If your DLL has any custom functions in DllMain then move them out ASAP. I ran into a lock problem on the DllMain of a COM object loaded under .NET; It's not quite the same problem but Microsoft told me to move all my code out of there.
Assert(this);

Hi,
I have a small doubt about Serialization in a scenaio.
When a WebPage is accessed, with its url (like http://xyz.aspx),
does any kind of serialization happen in the process of the accessing the webpage ?
I have read that objects will undergo serialization when accessed across boundaries. But not sure of this scenario.
Please clarify.
ThankYou,
Regards.

No, you are requesting a web page, not an object.
Some serialization might occur in the process of creating the response, like putting values in ViewState, but the creating of the response itself is not based on serializing.
