Thanks for the reply and yes! it is a sort of FileMon from SysInternals..

If you're trying to hook one application then you could do API hooking on the CreateFile, ReadFile, WriteFile APIs. This is a task that really needs to be done in C++. See here[^] for an example.
Otherwise you'll be writing a File System Filter Driver which runs in kernel mode, and for that you'll basically need to write in C. You'll need the Driver Development Kit[^] (I think - file system filters might be an advanced driver type only permitted in the Installable File System Kit[^]). Don't do this unless absolutely necessary - unstable applications merely crash the application, but unstable drivers crash the system. Kernel mode is very very hard, and you should at least read Windows Internals, Fourth Edition[^] by Mark Russinovich and David Solomon before starting.

Hi everyone,
I am developing a web service that references a dll. I've made the dll with some settings in the app.config file (the db connectionstring for example) I've also set those settings with GenerateDefaultValueInCode to false.
When I build the dll, it creates the .dll.config file correctly, but it looks like it doesn't use it. If I call the dll from the web service, the settings are all set to Nothing.
It looks like that with exe projects, you can put the settings in the .exe.config file, but in the case of a web service? I've tried to put the settings in the web.config but it looks like it doesn't work (maybe I did it bad)
Thanks in advance

.DLL's can't have their own config files, even though one was built. Any configuration settings must reside in the config file of the application using the .DLL.

Ok, is nice to know it  So I have to put the settings in the web.config file? In which section of the file should I put the settings? I put them in the appsettings but it didn't seem to work. Thanks again

I don't know off the top of my head. I've never written a .DLL or data access layer that required it's own config file. I've always had the application pass the connection string to the data layer when it was required.

You can put the settings in the exe.config file for the hosting exe. section names etc. stay the same, just the file name changes.

Hello,
I use System.Diagnostics.Process class to launch execuatbles. These executables are console applications and do not have user interface. I need to know if the processes I launched are busy doing some work or dead/stuck. I am not sure how to check that.
Any input on this would be appreciated.
Thanks,
Vidhya

How to test/monitor an application should be part of your design. When writing an application, consider using one of the following approaches:
1) Make your process write some status to a Console window
2) Make your process log some data to a logging DB
3) Add a little IPC interface to your program. Write a test harness to communicate with it.
4) Etc.
End-user tools like Task Manager/System Monitor are not accurate enough at this.
Best,

Hi chaps -
I have been experiencing all kinds of problems formatting a date to a string for storage or sending over a url etc. Now when using SOAP it generates this funky looking date time string:
'2006-09-01T16:15:43.359375+01:00'
What i want to know is - how do i generate this in my code, rather than relying on Date.Tostring("format") which invariably dies when it hits different cultures.
Cheers

The format you are seeing is the ISO 8601 standard format for date/time values. You should be able to generate this format by using the following format string for the DateTime.ToString() method:
DateTime.ToString("s", DateTimeFormatInfo.InvariantInfo)
This will give a string that looks like:
2000-08-17T16:32:32
It doesn't have the time zone information, but you can add that by using the System.TimeZone[^] class.
This shouldn't cause any problems when dealing with different cultures.

A bad habit of mine is to always re-invent the wheel, I just like figuring stuff out for myself and I'm sure that's the case with many programmers.
Right now, I don't have time to waste though....
Can anyone help me out with a quick algorithm (or article) for populating a TreeView in .Net?

Depends what info you are populating it with. It could be as simple as binding it to a XML file.

Hi Folks! I am using a class that puts data into excel worksheet and do formatting etc. Every thing is fine but i am not able to close the excel app when i exit the program. I'm saving the workbooks, using .quit() and ReleaseComObject(obj) functions but to no help.

Do you have a referance to the application? The following is How I do it in C#. VB should be simular.
Excel.ApplicationClass EApp = new Excel.ApplicationClass();<br />
Excel.Workbook EWrk;<br />
EApp.Workbooks._Open(FilePath, Type.Missing, Type.Missing, Type.Missing,Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);<br />
...<br />
EApp.Quit();<br />
EApp = null;<br />
EWrk = null;
Hope this helps.

While debuging set the APP to visible, making easier find the problems like a "Would you like to save changes" dialog. You will get no indication in your app if it is excel tripping up.

I want to make a .NET application in C# that can act as an active document server. To my disappointment I can't find any support for it.
Has anyone implemented the interfaces that are necessary to support it in .NET?
What would be the typical alternative to active document in .NET?

Excuse me for a quick noob question:
Let's say a component of my C# application throws and exception. I want to catch it and handle it, but!
I have try...catch in program.cs around the whole Application.Run(new FormMain()); and yet the system itself somehow pops the "application error" dialog with the whole backtrace and all. I'm guessing it's catching the exception sooner somewhere handling my FormMain execution. Where would I then place the whole form wide exception handling to intercept it before the .NET code?

I might be missing something, but it sounds like .NET can catch the exception raised in your code before you can. If you don't know where exactly the exception could be raised, you needn't do anything. If you do know the exact code segment, try to catch and handle the exception before .NET does.
Best,

Try handling the AppDomain.UnhandledException event. However, you should find the cause of the exception and handle it at the point closest to where it is being thrown

If you click and hold on a regular Button control and then press alt+tab (without releasing alt), the button will go into it's normal unpressed state. I wish to do the same with my custom control but have been unable figure out how to detect when the user presses alt+tab as the LostFocus event doesn't fire until alt is released.
Any ideas on how MS did this?

Hey Everybody!
I'm not sure if I'm in the right forum, so if not, just tell me and I'll rewrite it again in the right place  Thanks!
I started to read and understand "Extending Explorer with Band Objects using .NET and Windows Forms" article and I'm trying to understand what is GAC and strong name.
I've been looking for an article that will explain GAC, but I couldn't find a good one that explains the basic idea.
from what I understand (which might be wrong!), GAC is a global assembly that "contains" DLLs that can be accessed by any running program on the computer.
each dll has a "strong name" which is destincs to each DLL and using that strong name programs can "talk" with this dll.
if (all of the above is right (or at least partial right))
{
how do I assign a dll to the gac (without the registerLib in the article)?
do I have to reassign it everytime, or I need to do it once?
how do I remove a DLL from the GAC?
and last one, how do I read from the GAC? (I saw an article about it, but it would be nice if someone would explain it anyway ).
}
Thanks ALOT!!!
