First please please delete your duplicate LONG message.
Second: You have to try this on ASP.NET furom.

The place for sorting is there and you havve to set SortExpression there. Why do you say you don't want to do it in that event?

1) The above code which I posted is working fine, but does not trigger DataGrid.SortCommand Event, when using BoundColumn. If I comment BoundColumn Code and set the DataGrid.AutoGenerateColumns to true, then the DataGrid.SortCommand Event in code back file is triggered properly.
2) If I dont use BoundColumn then I cannot set the Visible for last column (eg. Column No 7) to false, as DataGrid.Columns.count is always 1. The reason I get DataGrid.Columns.count as 1 is because first column in DataGrid is Template Column.

When using non-blocking I/O in C++ a simple send() call could fail with WSAEWOULDBLOCK and the data is put in a message queue. When a FD_WRITE is coming in you can try send it again.
I wonder if this can happen with asynchronous sockets in .NET?
Can a send fail with WSAEWOULDBLOCK so that I need to use a message queue or does the framework do the second send for me?

Hi
I am developing an ASP.NET C# Mobile Application. It works fine when I run it in a browser but if I run it on the openwave WAP emulator it is giving me an error, Malformed server response, when I try to go to the next page. I was thinking it might have something to do with the function I am calling to get it to go onto the next page, the function is RedirectToMobilePage(url). Any suggestions would be great.
Thanx
Rosie

Is this a server- or client-side function? Are you sure that WAP implements a scripting engine for Javascript? I honestly don't know since I've never cared to deal with mobile apps.
If this is a server-side method, are you canceling the response or letting the response complete. In most cases, you want the latter, otherwise an exception will be thrown if not handled correctly. So you should call RedirectToMobilePage(url, false);.
Also, this really belongs in the ASP.NET forum for future reference.

i can't load a Mesh into my directx App as it views as empty one
but when i see it in the mesh viewer utility it is there and i can see it

Sounds like you're not resolving the path to the file correctly. If your .X file is stored as a separate file, make sure you take the current working directory into account (may not be the application base), or use the application base by using Assembly.GetExecutingAssembly().Location. IIRC, the Mesh class can also accept a Stream, so if you embedded the .X file as an embedded resource, you can use Assembly.GetManifestResourceStream to get an instance of a Stream for the resource.

Hey
Is it posble to have controls like buttons, pictureboxes, and maby own made controls.
I have loot at the ListView.controls.add, but i dont get this to work and am not sure if this even have somthing to do with the windows form controls like buttons, pictureboxes etc.
Pleas help

You can't add controls to the ListView like that - it's not a container. You can add controls but you need to owner draw everything, and I remember giving you links to a couple examples here on CodeProject. Use those and read about the List-View[^] common control for information on messages, notifications, styles, and such. .NET doesn't currently expose any simple way of doing this - you have to revert back to Win32 methods.

I think you can start with FileSystemWatcher control.

You should look into Windows Hooks[^]. C# is really not the best language for this. C/C++ would be better suited for something that needs to be fast and may or may not load in-proc with other applications.
For more information on Windows Hooks, see Hooks[^] in the Platform SDK.

Hello Benzite!
If you enter into the article area, go into General C#, and enter the COM Interop list you will find a number of articles there. The two specific articles you want pertain to the IDocHostUIHandler hooks.
This is the link to my article:
http://www.codeproject.com/csharp/winformiehost.asp[^]
This is the link to Nicks article:
http://www.codeproject.com/csharp/advhost.asp[^]

Yep, and lets just let all the wannabe programmers breeze through life without doing their own work or looking things up. Congratulations for fostering the problem with this industry.
Besides, both articles you listed appeared at the top of the search results I linked anyway. I guess two clicks is one to many for you both? Oh, the pain...

I want to develop an application that will not require the user having MS SQL or ORACLE or even Access (MS Office). Also I envisage that my data will accumulate to quite a large volume so I do not wish to use XML. What I am looking for is information on how develop and deploy a windows application with MSDE or JET. I would obviously deploy JET or MSDE with my application.
Any relevant refs?
Thanks

MSDE is engine of SQLServer which doesn't have user interface and some of those tools exist with SQLServer. Now whats your problem which you need refs about?

Using .mdb files does not require Microsoft Access - it's merely a development environment for Jet databases. To distribute Jet databases, you must install the Jet runtime, which you can download from http://www.microsoft.com/data[^]. This is most often installed already on client machines. Note that Jet is not currently installed with MDAC (there were prior to 2.6). For information about downloading the Jet runtime, see KB article Q239114[^].
The MSDE - while providing a true RDBMS - can be more difficult to deploy. The MSDE - like SQL Server, of which many components are shared - can only be installed for 16 instances, including those instances that are SQL Server. In the MSDE downloads, there are 16 MSIs (Windows Installer Databases). Most applications will pick one and stick with it. Each one contains a different ProductCode that you can use for upgrades (such as SP3, which I think is part of the base MSDE install now). Some applications - such as ours - will even distribute all 16 MSIs and use a boostrap that will determine which one should be used (in case another product has already installed another instance using the MSI that we might've picked). This definitely adds to the complication. You could always use that existing instance and attack your databases, but then you have two or more products tied together with a single instance that might lead to additional problems (like if the other product upgrades the master table and breaks some of your functionality).
You can read more about MSDE deployment on the MSDE site at http://www.microsoft.com/sql/msde[^], as well as download it and its service packs. Note that VS.NET also includes the MSDE set (a single instance named VSdotNET).

When I try to compile my application it always displays the error message, "Static Member '(control)' cannot be referenced with an instant reference; qualify it with a type name instead." I access most of my controls that are on this form from other forms, so at the beginning of the class when all of the controls are declared as private automatically, I changed them to public static.
I Changed This:
private System.Windows.Forms.PictureBox pboBoard;
private System.Windows.Forms.MainMenu mnu1;
private System.Windows.Forms.MenuItem menuItem1;
private System.Windows.Forms.MenuItem menuItem2;
private System.Windows.Forms.MenuItem menuItem3;
private System.Windows.Forms.MenuItem menuItem4;
private System.Windows.Forms.MenuItem menuItem5;
private System.Windows.Forms.MenuItem menuItem6;
private System.Windows.Forms.MenuItem menuItem7;
private System.Windows.Forms.Label lbl4;
private System.Windows.Forms.PictureBox pboP1;
private System.Windows.Forms.PictureBox pboP2;
private System.Windows.Forms.Button cmd1;
private System.Windows.Forms.Label lbl1;
private System.Windows.Forms.Label lbl2;
To This:
public static System.Windows.Forms.PictureBox pboBoard;
public static System.Windows.Forms.MainMenu mnu1;
public static System.Windows.Forms.MenuItem menuItem1;
public static System.Windows.Forms.MenuItem menuItem2;
public static System.Windows.Forms.MenuItem menuItem3;
public static System.Windows.Forms.MenuItem menuItem4;
public static System.Windows.Forms.MenuItem menuItem5;
public static System.Windows.Forms.MenuItem menuItem6;
public static System.Windows.Forms.MenuItem menuItem7;
public static System.Windows.Forms.Label lbl4;
public static System.Windows.Forms.PictureBox pboP1;
public static System.Windows.Forms.PictureBox pboP2;
public static System.Windows.Forms.Button cmd1;
public static System.Windows.Forms.Label lbl1;
public static System.Windows.Forms.Label lbl2;
Now, there is no problem with the outside access of these controls, but when the components are initialized, it doesn't recognize the reference, "this". The only thing I could think of was changing, "this" to, "Form1"
I Changed This:
public void InitializeComponent()

This created some problems as well; all of the error messages would dissappear, but when I would go under the Form1[Design] tab, all of the controls would dissappear. I would compile the program without any problems; the controls would display, but nothing would work, it would be like there would be no code at all. I have no idea what is wrong, could someone help me out?

How about providing a code sample next time  
Were you maybe trying something like this
<br />
MyForm form1 = new MyForm();<br />
form1.StaticCtrl<br />
If so then try
<br />
MyForm.StaticCtrl<br />

Besides what Mark said, you don't want your controls static. You actually attempted to fix the original problem in exactly the opposite way that the compiler error implied. You shouldn't make your instance members static, but make your instance qualifier for your static method a Type like Mark said.
Trying to add static controls to a form won't work. With some careful handling, you might be able to get it to work for one form, but additional instances of the form will throw exceptions or even kill your app because window handles (which back the controls in Windows Forms) cannot be shared by parent windows.
