I am now working on my dissertation.My teacher give me the project.
It is "use .net to implement Internet message platform(it includes 5 titles,"use UML to build message platform","implement the client" ,"implement the Server","log in and users management","test"),I choose "implement the client",my teacher wrote them in chinese,I just translated them to english,maybe some words are not very exact.I will explain.My teacher said the knowledge of UML and .Net would help.
So can somebody tell me what is "internet message platform" and lead me to a right direction.Many many thanks here first.

This is not a good place to ask, no-one reads it  Try the C# forum in future, I reckon.
internet message platform == MSN Messenger, ICQ, etc. It's a program that allows people in remote places to use the internet to type messages to each other in real time.

Hello,
is it possible to get to know, how the user moves the mouse if the cursor is at the edge of the display? I mean, can get some delta values of the mouse (not the absolute values that are limited to the dimensions of the display)?
best regards,

The VS IDE Installer provides a very limited set of tools to author Windows Installer packages. To create more advanced customized setups you either need an authoring tool like InstallShield or you will haved to manually author the MSI yourself. Microsoft provides an SDK and tools that allow you to manually author MSI packages, but it is very difficult and time consuming.
You can download the SDK here:
http://www.microsoft.com/msdownload/platformsdk/sdkupdate/default.htm?p=/msdownload/platformsdk/sdkupdate/SDKInfo.htm[^]
Beyond that, you will just have to study the SDK documentation. There is no simple answer to your questions other than no, there is no other way to author MSI packages available in VS.NET.

Inside the MBR object, you can try
ILease lease = (ILease)InitializeLifetimeServices();
lease.InitialLeaseTime = TimeSpan.zero;

I'm looking for a tutorial on how to dock forms within other forms.
Example.
Menu > Tools > Enable Form1
The form then appears, within the current form.
I hope I'm being clear. Thanks.

Hi,
The following link has some information about docking.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbtskDockingControl.asp
But i guess you can solve your problem by creating an MDI application.
Thanks

I am very confused by .NET ASPX page processing model. I am using C# and creating simple database data dependant dynamic form with bunch of generated buttons.
After that I am catching server side processed standard onclick events on these buttons and in onclick event function creating some other dynamic elements such as textboxes and other buttons.
When I am pressing on new one created buttons generated outside page_load function - page reloads and these elements (of course) is lost! Now I am using some sick mytype in Session wich holds my dynamic cotrols and restores them by page_load. I suppose this is not the recommended way to do things (but for now) it works very well, maybe there is some logic and normal way to hold dynamically created elements in page. And I am wandering why .NET guys destroys page instance on each event?

The Page object has a bool IsPostBack property. Put your form loading code inside an "if" statement only if IsPostBack is false.

To create a batch file just create an empty file with .bat ending (in the same folder as the msi) and copy your command into it.

When I try the webservice sample code "hello world" in the Visual studio .net 2003, I seem always have problem on authetication or authoraztion. I just remove the "'" according to the explanation in the comment to change serveral line of comment into code. and Press F5 to debug it . or try http://localhost/webservice1/webservice1.asmx in the brower.
At first, I got an error "Access denied". I thought it may be ananymous access from ASPNET account or IUSR-XXX need administrator authorization. I put them into administrator group. But it does not work. I also put debugger users group and VS developer groups have administrator authorization. It does not work. I got some other server-side error as "The Web server reported the following error when attempting to create or open the Web project located at the following URL". I also change some setting on dedault web site of IIS as application protection to Low and put ASPNET account or IUSR-XXX, debugger users group and VS developer groups all have administrator authorization . But I do not know why. As the explanation in the help or book, it should not be so difficult.
My environment: window 2000 server, IIS 5.0 Visual studio .Net 2003.
My question is for the simpliest webservice. If i only try in the IDE, what
do I have to set?
My email address:Bretthlin@hotmail.com or linhchnn@yahoo.ca

Hi,
Try this instead.
private void panel1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Refresh();
}
Hope it helps.
Cheers.

Doesn't it seem like this will be the order of events?
* (Your code) Create graphics object
* (Your code) Draw on pane
* (Your code) Refresh pane
* (WinForm code) Clear background (thus removing your previous drawing)
* (WinForm code) redraw pane
It might be that your drawing is getting painted over when you refresh your pane.
You can create a delegate and add it to the pane.Paint event, then draw using the supplied graphics object.
