LastAccessTime indicates when the file was last read, not when last written. You probably want LastWriteTime.
To stop the file system constantly writing the last access time, by default it updates once an hour. See Optimizing NTFS Performance[^] (from the XP Resource Kit) for more details. You can apply a registry setting[^] to disable the Last Access Time updates completely. It sounds as if this has been done on the PCs you're testing with.

Hi
how i can call a webmethod from outLook
i want to place a link on taksItem when clicked
download a file form webserver.
thanks

Im not quite sure if by webmethod you meant webservice, but if you did then you might be missing a reference. What you must do is add a web reference to your project and include it at the top of your file (by the keyword "using"). Then you simply call the method like you normally would.
What part exactly is hanging you up?

I dunno why I can't draw a curve as I want it.
Graphics g = new Graphics();
Pen p = new Pen(Color.Black,1);
PointF[] list = new PointF[2]{new Point(1,2),new Point(2,3),new Point(3,4)}
then.. g.DrawCurve(p,list,?,?);
What I should do ? do you can guide me to one good example ?
Why the start point always is (0,0), always the curve starts by the left high corner of my win application !!
Thanks..

That statement is wrong. You have 3 elements, not 2. Don't declare an array size when you specify the array elements when you instantiate the array. The following is common and better:
PointF[] list = new PointF[]
{
new PointF(1f, 2f),
new PointF(2f, 3f),
new PointF(3f, 4f)
};You're also using the wrong type. If you're declaring an array of PointF, the elements must be PointF. Frankly I'm surprised it even compiled. Declare and instantiate list correctly and you should see the results you want.
Have you read the documentation[^] for the Graphics.DrawCurve method? There's an overload that doesn't even require a 3rd or 4th parameter, and which can take either a Point[] or PointF[]. It's important to understand what the documentation says. There's also several examples for the method.

Hello there,
With this code:
<br />
...<br />
<br />
cmd = new SqlCommand( "insertData", conn );<br />
cmd.CommandType = CommandType.StoredProcedure;<br />
cmd.Parameters.Add( "@Name", strName );<br />
cmd.Parameters.Add( "@Data", stream.GetBuffer() );
<br />
int nResult = cmd.ExecuteNonQuery();<br />
<br />
return nResult;<br />
What will the value of nResult be if the insert operation is successful? It should be at greater '>' than 0 right?
This is weird because I'm getting a value that is not > 0, but as I checked the LastUpdate field in my database, the value is correct (which I assume it means that the data was inserted successfully). And yet, as I looked up MSDN, it should return a value of > 0.
What could be the problem?
Thanks,
~Rafferty

Hi
I have done a program , here The program reads any xml schema file and automatically writes 200 data's to a xml file(name as result.xml)according to their data types.
say for string-john1, john2,john3...etc..
say for decimal-101.20, 102.20, 103.20 ..etc.. so on.
And the program also reads a xml file with single field named address(for ex . so the program what it does is checks the schema file whether there is any element named "address" and it stores the fieldnumber(position of the field) and the field name in an array.
then the program reads a another input xml file(which has address values ). then it stores the values from the input xml file into the resultxml
I have done it and I am coming across some errors.I will paste the part of the program what I did.. Please help me to sort out the error.

At a quick glance I noticed that your first "for" loop is incorrect.....
What is the exception you're getting?

hi,
i found a form can't be destroyed after registered for the Main form's timer event. below are 2 methods used to create the form. one register with timer event, one without. i can see that the destructor of the one without timer event registered will be called after i open and close the form several times. but, the one with timer event registered. destructor will be called only when the main app exit.
so, any method to help?
<br />
private Form2 frmbulk;<br />
private int counter;<br />
private void button1_Click(object sender, System.EventArgs e)<br />
{<br />
Cursor currentCursor = Cursor.Current;<br />
Cursor.Current = Cursors.WaitCursor;<br />
<br />
frmbulk = null;<br />
frmbulk = new Form2("Form2_"+System.Convert.ToString(counter++)); <br />
<br />
this.timer1.Tick += new EventHandler(frmbulk.TimerEventHandler);<br />
frmbulk.Show();<br />
<br />
Cursor.Current = currentCursor;<br />
}<br />
<br />
private void button2_Click(object sender, System.EventArgs e)<br />
{<br />
Cursor currentCursor = Cursor.Current;<br />
Cursor.Current = Cursors.WaitCursor;<br />
frmbulk = null; <br />
frmbulk = new Form2("Form2_"+System.Convert.ToString(counter++)); <br />
<br />
frmbulk.Show();<br />
Cursor.Current = currentCursor;<br />

Hi,
if object A (frmBulk) registers an event of object B (timer) it is like B would have a reference to A. Thus to free A you will have to unregister the event. So if you dont need the form any more:
<br />
this.timer1.Tick -= new EventHandler(frmbulk.TimerEventHandler);<br />
Btw: I dont think its good style to bind an event of object A (timer) to an object B (frmBulk) within a third object (main). I think it would be better if main just registers the event itsself and then just calls a method in frmBulk. To free bulk you would then only need to set the private field to null.

Well in my project in need of following menu extensions
a) make tooltips appear on mouse over the menu item
b) how can i organize the menu in multi columns - currently in one contex menu have about 100 items, whant to organize them on two panels, link "All Programs" menu in Windows
Regardless

You'll have to ownerdraw the menu and draw the menus yourself. There are no properties to support columns in the menus.
Tooltips, I don't know about. I don't think they're supported. I also don't remember seeing them in any application, at least, not in any normal application that doesn't ownerdraw everything.
But, something to think about -> If I opened a menu and saw a hundred items in it, I'd click Close, then Add/Remove Programs, Uninstall.

Set the BarBreak property of a MenuItem to true to start a new column in a context menu. For instance:
contextMenu1.MenuItems[2].BarBreak = true;
-----------------
| item1 | item3 |
| item2 | item4 |

Hi everyone!
Has anyone ever worked with WMI i.e has anyone done any work which involves exposing data to the WMI repository?
I have created a WMI namespace with a managed class in it but it does not seem to accept the creation of instances, which is what it should happen when I expose an instance of a .NET class by publishing it to the WMI. The only way that I can create instances is if I create a sublass and then create instances of it either manually using the CIM Studio tool or using MOF scripts. Am I missing anything? The example given by MS seems to be fairly simple and strightforward and I followed it to the letter, but id does not want to work for me.
Can anyone offer any help?
Thanks,
Marjan.

See the documentation[^] for the ManagementClass.CreateInstance method which includes an example of how to create an instance of a class for which you're providing instances.

Thank you very much for the reply Heath. I'm now able to create instances. However, it is interesting how I can only create instances on a subclass of my class, and not on the class itself. In any case, now I can write to WMI which is the main thing. 
What will we do without the net?
Regards,

You can handle a number of Windows events using the Microsoft.Win32.SystemEvents class, which defines several static events.
For handling events from other arbitrary applications you need to hook native Windows messages. Search this site for "SetWindowsHookEx".
Please note that great care must be taken and you really should understand just what a Windows message is and how to write your managed code efficiently and robustly. When you hook native Windows messages you're responsible for the stability of not just your application but all of Windows. You must not throw exceptions, do long operations (like database look-ups), or anything that could slow down the machine. Remember, you're hooking a Windows message before it's dispatched to the destination window and Windows will wait for your handler to return. You could seriously compromise the stability of Windows, so take such a task very seriously and write good, clean, robust code.

In my .NET solution I have a project which has the controls I have developed for use in the main project. If I add the controls in that project to the toolbox I am adding them from the Debug directory. When I compile the controls for release will the main project still be referencing the debug code?

Its not important how youve dragged the controls into the toolbox. Its important what reference your main project has. If it has a real project reference to your project with the controls then everything should be fine when building in release mode.
|
|
|
|
|
Thanks, how do I do that? I just tried building in release mode and every control from the control project dissapeared. I added the controls to the toolbox using the add/remove dialog and then "browse"
|

Right-click on your project and select Add Reference. Click the Projects tab and select a dependent project in your solution. This makes sure that you're always building against the most up-to-date assembly (because it establishes a build dependency) and that you're using the right build configuration (so a release build uses the release assembly from the dependent project).
Any control extending UserControl appears automatically in the toolbox. Do not add it yourself. In fact, don't use the toolbox for the project you're developing within the solution. You'll be changing them often. If you develop in-house controls for use in a project, control the release cycle similar to how you would for a public project and then you could add them to the toolbox. The toolbox is meant for stable controls, not controls you're developing otherwise you will have the problems you're having.
If you need to add a control you're developing to a container control initially, add it manually. It's not hard. Open the source code for the container control (like the Form you're designing), add a private field like you see for other controls, then instantiate it in the InitializeComponent method like you see for the other controls. When you switch back to the designer you can design it like all the other controls you added from the toolbox. It's a one-time process that only takes a few seconds, compared to the time you'll be spending working around problems with adding controls in development to the toolbox.

Thanks for replying.
That's exactly what I am doing. I have a control which inherits from Control so it doesn't appear in the toolbox so I instantiate it myself - however the IDE just gets rid of it sometimes - I thought we weren't supposed to change any code in IntializeComponent.
I have project references in the main project but as soon as I switch to Release build all the controls from the controls project disappear from the main project.
I have been at this for a while now and can't get it to work at all.

You might have covered this already, but did you check the AssemblyVersionAttribute tag, in assembly.cs if you have one, to make sure it doesn't have any * in it? Replace the * with a number so the version number stays constant from build to build while your developing your control.
