is there any way to promote programatically a directory
(located within inetpub directory subtree) to web application?
Also I would like programatically add new IASPI mapping
(for some custom file extension to particular DLL)
for this newly created web application.
Thanks for help

You can do both programmatically using either the IIS WMI provider or the ADSI provider.
For the WMI provider, use the System.Management classes, and for the ADSI provider use the System.DirectoryServices classes.
Try the following google search for lots of examples or refine it to find exactly what you want. Documentation for the IIS WMI and ADSI providers can be found on MSDN[^].

Hi EveryBody,
I used the later code to handle some messages sent to my application
and it works, but my question is how to handle messages sent for child applications of my application(parent)
<br />
[System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name="FullTrust")]<br />
protected override void WndProc(ref Message m)<br />
{<br />
switch (m.Msg)<br />
{<br />
<br />
case WM_SIZING:<br />
MessageBox.Show("Sizing");<br />
return ;<br />
case WM_SIZE:<br />
MessageBox.Show("Size");<br />
if(m.WParam==(IntPtr)SIZE_MINIMIZED)<br />
MessageBox.Show("SIZE_MINIMIZED");<br />
else if(m.WParam==(IntPtr)SIZE_MAXIMIZED)<br />
MessageBox.Show("SIZE_MAXIMIZED");<br />
return;<br />
<br />
case SW_MAXIMIZE:<br />
MessageBox.Show("SW_MAXIMIZE");<br />
return;<br />
<br />
case WM_MOVING:<br />
MessageBox.Show("Moving");<br />
return;<br />
}<br />
base.WndProc(ref m);<br />
}<br />
<br />
Please I need a very fast help.
Thank you .

Child applications? There's no such thing. Are you talking about child Windows or MDIChildren? Each form has it's own message pump. Your parent form will not get the messages meant for child forms.

Dave's right about the message pump. Some controls will send their parents messages, and these are documented in the Platform SDK (almost every control in Windows Forms encapsulates Windows Common Controls).
There is another way, though. Implement the IMessageFilter interface and add an instance of your implementation using Application.AddMessageFilter. This installs a message filter for the application's message pump, which will trap messages and allow you to process them (or even remove them) before dispatching them to their destination windows.

I can serialize my class with xmlserializer.
but when i add a DataTable typed property to my class, xmlserializer submit an error to me.
please guide to me.

We need the error mesage you're getting. We also need to know how your adding this DataTable to your class. Some code snippets would help alot.
Without these items, it's impossible to tell you what your doing wrong.

I creat a component that have a collection object.
when i use this component on my form, and fill collection and save form, the collection`s contetnt not save into form`s resource.
please guide to me.
|

|

If by "form's resource" you mean the ResX file, then you have to use a CodeDomSerializer derivative that uses the System.Resources namespace classes.
If you want to simple serialize the collection to code in your .cs source file, then just use the DesignerSerializationVisibilityAttribute:
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public MyCollection MyObjects
{
}That's it.
If you want custom serialization, again extend CodeDomSerializer. If all you want is to serialize a collection like a ComboBox would for items, for example, then just use the attribute and enumeration value I mentioned above.

Hello.
Thank you very much for your guiding. it is very interest.
I use "[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]" in a collection that contain "int" data type and it is ok. But when i use this attribute for a collection that contain a class or struct , it is not work , mean that the contect of content class of collection not save in form code.
please guide to me again, very very thank you.

Hi!
I’ve read about a topic like this earlier. I would like a program to generate a picture of my programming project from my .sc (C#) or my .h (C++) files.
Anyone got a tip of a good free alternative? I’m using VS.NET and would be very happy if I have a solution there…
I’ve heard about MS Visio but is there a possibility to load existing files in the way I want?
...and justice for all

Microsoft Visio Professional adds a plugin for VS.NET that will generate a UML diagram for your project.
Rational XDE (got $2,500 bucks to spare?) allows you to do this from within VS.NET and synchronize your class diagram with your project.

Actualy i have Microsoft Visio Professional.
Where do i find and use the plugin in VS.NET?

It was an install option when you installed Visio. It's only available for VS.NET 2003, IIRC. It should've installed by default. Just click on Project menu and you should see a Visio UML menu item.

Please HELP.
I have class hierarchy model (a.k.a. an Object Domain), where I store my data. This objects are finaly stored in ArrayList that I use as DataSource for my DataGrid.
This idea corectly works with fixed columns count, because objects in ArrayList have property for each column and DataGrid maps this properties.
How can I customize my model for variable columns count?
I try to change my structured objects to collections and properties to array property. However, in this case, DataGrid can't map this property and columns can't be append.
Any help is much appreciated.
Sincerely,
Morfo

What is the use of following method?
Graphics.AddMetafileComment(metaComment);
where do and what for we use MetaFile Comments?
Please guide

Yes
I have seen it, it says what it is and how to do it, nothing is said about why and where it is required.
thanks

It adds a comment to a metafile (.wmf, .emf, and other supported properties). Not that the name implies that or anything.

Since when are comments required in anything?
They're no different from // in C, C++, C#, or REM or ' in Visual Basic.

How do we again read those comments using C#?
regards
|
|
|
|

You would have to use the Graphics.EnumerateMetafileMethod to playback the metafile records and pick out the Comment type records you want. When you call this method, you have to supply a EnumerateMetafileProc delegate to the function so it can call your record handler with each record in the file. Your record handler wouldhave to pick out the Comments as they were sent to you...

1. I have a class, called 'UserManager'. The UserDataSource propertie is presented below:
///
///
///
public DataSet UserDataSourse
{
get
{
DataSet dataset;
dataset=mLibraryItem.Copy();
return dataset;
}
}
Note: mLibraryItem is a dataset which stores current data of the User.
2. I have a Windows form, form1. I add a combobox to form1 and perform the bind data using the formload event:
usermanager=new UserManager();
comboBox1.DataSource=usermanager.UserDataSourse.Tables["User"];
comboBox1.DisplayMember="UserName";
Result: The number of items in the combox is correct but the Username isn't displayed in the combobox as expected. The System.Data.DataRowView is shown instead
Please advise how to solve this problem.
Thanks,
Uyen Chi
