Ok, lets look under the hood of what works:
Console.WriteLine(string,params object[])
which you are calling internally calls
Console.Out.WriteLine(string, params object[])
Console.Out is a TextWriter instance, so:
TextWriter.WriteLine(string, params object[])
Internally this calls
String.Format(String,params object[] args);
so finally in answer to your question this will work:
string strLine = String.Format("{0:00000}",i);

How to access WAB(windows address book) from c#?
It is my start:
static public extern uint WABOpen(ref System.IntPtr lppAdrBook, ref System.IntPtr lppWABObject,ref System.IntPtr lpWABParam, uint Reserved2);

The following code is part of my program:
<br />
string folderToWatch = @"d:\html\";<br />
FileSystemWatcher fsw = new FileSystemWatcher(folderToWatch, "*.html");<br />
<br />
fsw.Created +=new FileSystemEventHandler(OnCreated);<br />
<br />
fsw.EnableRaisingEvents = true;<br />
It works perfectly om my laptop running Windows XP SP2. But not at the server running Windows Server 2003.
Any suggestions why?

For testing purpose the process is ran by the Administrater - so this should not be the problem.

I'm not sure of the underlying API's that the FileSystemWatcher class uses, but I know of a problem with using ReadDirectoryChangesW() for the Windows API. When I was using this function in a C++ project, it wouldn't work because the folder was actually a unix drive that was mapped to my machine, and looked like a regular windows folder. So I don't know if that class is using the same API underneath, but that API doesn't work on non-Windows drives. Your problem may be different, but possibly related. This may not even be near what the actual problem is, but hopefully it might get you thinking about any other possible anomalies in the way that folder is accessed.
If I write code in my sleep, does that make me brilliant, or just a lazy programmer?

Hi!
I was wondering how I could manually create a RCW for third-party ActiveX controls.
Creating 'regular' RCW's for COM dlls is quite straightforward, just running the dll through tlbimp.exe and I get the RCW.
Now when I add an ActiveX control to a form with VS, an AxInterop.Componentname.dll is created, along with Interop.Componentname.dll.
The second dll (Interop.*) seems to be equivalent to what I can create with tlbimp.exe, but what about the AxInterop.* ?
Can anyone shed some light on this subject?
TIA,
Mav

Mav, the AxInterop assembly that is created literally wraps the ActiveX control to expose it as a Windows Forms control, it's base class is AxHost. You typically wouldn't want to create this manually, however you can use the Aximp.exe[^] (Windows Forms ActiveX Control Importer) to generate this assembly yourself.

Thanks alot, Nick!
I was asking because I have to support two different versions of a third party program exposing ActiveX controls and COM objects in my program.
The problem is that the interfaces of these objects have changed but have kept the same name. So I couldn't find a way to instantiate a class implementing a specific interface version and am now trying to use 2 RCW dlls with different namespaces.
Don't know if this will work, though.
The core problem is: I can't have both versions of the application installed at the same time, so I must build against the version currently installed. When I build against the newer version, I'll get class not registered-errors when instantiating objects with the older version installed. The other way round I can't use any features from the newer version.
You don't have an idea how to do this by chance?
Thanks,
Mav

I am doing some code profiling on my project to try and identify any speed bottlenecks - I am using DevPartner community edition from Compuware - when I run the tests my project spends about 90% in WaitForSingleObject, Sleep and SleepEx - why would it do that? The program isn't multithreaded and the main part of the program I am testing has no user interraction - it's basically some IO and a lot of bit shifting.
TIA

You have to wait for the I/O finish. Often this is done by the CLR using WaitForSingleObject, because some I/O classes only implement asynchronous interfaces (Begin*/End*) - the synchronous versions of these methods simply call the Begin/End pair.
What you're seeing is that your program is spending 90% of the time blocked by I/O. Maybe multithreading would help you a bit.

Thanks for that. It isn't really a problem as the program is fast enough - analyse 1 billion records per second anybody? I was just curious why it was spending so much time sleeping and waiting.

Hi,
Does anybody has any idea how to give implementation in c-sharp, of the following feature of Yahoo or MSN:
Show me as "Away" when I am inactive for 10 minutes.
I have a chat client application developed in c-sharp. And now I want to give the same feature in my app too.
Prompt reply will be appreciated.
Regards,
Kamran

You could take a timestamp everytime the user of your application does something and store it somewhere. This timestamp value then gets compared with the actual time inside of an timer event handler and if the difference is greater than 10 min you set the status to "Away".

Simple solution - have a timer that ticks every so often (depending on how accurate you want your away timer to be)
Every time the timer ticks, increment the counter, when the counter goes above a pre-set value (i.e. how ever many timer ticks there are in 10 minutes) you can set your status to away.
Now, in any of your mouse/keyboard handlers, just reset that counter to zero if you've got user input

Hi Benjymouse,
Thanks for your prompt reply. It helps me a lot to understand the solution.
But how to capture mouse/keyboard events of windows. Remember my chat application application needs to be notified of any activity on windows for example if my chat application is minimized, and a user only moves his mouse on the desktop, my application should be able to capture this event.
I hope you understand what i mean.

Kamran

hi there,
How can draw shapes inside a control( a custom label control). The real idea behind this is, partitioning status through this control. Otherwise how can i partition a label control with different region.

overload the paint method of the control with what you want it to show...
|
|
|
|

I tried but failed. Reason is i need to split the entire size of controls into three different region and then need to get a block from that. This block need re design at run time based on user request(re design means - > assign back color,fore color,outer line color and highlight color etc). Some time user may merge any two block of region into one or the entire three block into one. So i am in trouble. Any idea ?

I load my data into Datagrid, I'd like open a new form(contain the data about this row) by clicking on each row of the Datagrid . How can i do that ???
|
|

Use HiteTestInfo class which contains information about a part of the System.Windows.Forms.DataGrid at a specified coordinate. See MSDN for more details.
Eg:
<br />
System.Drawing.Point pt = this.dgUnAllocatedOrders.PointToClient(Cursor.Position); <br />
DataGrid.HitTestInfo hti = this.dgUnAllocatedOrders.HitTest(pt); <br />
if(hti.Type == DataGrid.HitTestType.RowHeader) <br />
{ <br />
Yourform alloc=new Yourform();<br />
alloc.ShowDialog();<br />
}
