Be specific - what exactly do you need help with. You just made a series of vague comments that no one can really use to help you.

G'day folks,
I just implemented a winform containing a listview. The listview simply lists all the files present in a directory with the name and its respective icon in one column. As I was trying to get an understanding on how Win32.SHGetFileInfo works.
The process of actually adding the information was done via a separate thread. What I had discovered that if one of my files contained an outlook message file, it will not display the icon for outlook instead it displays the generic windows icon. The generic windows icon is the same as when windows os cannot seem to associate an application with a file.
Now if I were to display the files and its respective icon in the listview without the assistance of a thread, the outlook icon appears in the listview. So far it works fine with any other file ie. txt, word, excel etc. The samething happens with .net 1.1 and 2.0
Anyone got any ideas as to why this would be happening ?
thanks

thanks for the reference. I always saw BeginInvoke but didnt realise what it did till now.

I have an interesting problem that I am looking for some advice on. Basically I have a protocol library, where each PDU is a class. Thus the library is a collection of individual classes that are stateless.
Meanwhile, I have a need to aquire some housekeeping info via a one time register function. I'd like for this function to make the housekeeping info persistent or semi-persistent so that thet data would be available to the other classes as they are instantiated.
Now, I could use XML to write out persistant data but the overhead in file I/O seems quite underdesirable in a near real time application. I could write a value to the Registry, but again there is a performance hit. Finally I have considered kicking off a thread which the instantiated classes could interrogate but that feels over the top.
If only you could create a Shared Memory Region like the good ol' days (just kidding). But if you have tackled a similar problem, or know of an elegant approach please let me know. Thanks in advance!
Mike

What's a PDU?
If all this is happening in one application then reading an XML file at start up then holding the data internally isn't too bad. The other classes could then query the central housekeeping class. If it needs to write stuff out to persist it then it could do so when the application is shut down or at regular intervals so it doesn't disrupt the flow of the rest of the application.

PDU usually refers to a Power Distribution Unit, used to switch between main power and backup generator power seamlessly with no loss of power.

Sorry for the confusion, PDU means Protocol Data Unit (i.e. a packet) in data communications and in my library.

I have a finished implementation for activation that relies on the manufacturer assigned non-changable serial number of a hard drive. During testing I discovered that my method of discovering this number does not work on all versions of Windows that are going to be supported. The WMI claass Win32_PhysicalMedia does not exist in Win2k. The workaround for this is also very painful, requiring DeviceIoControl and probably administrative priveleges at runtime. I noticed that there is Wmi32_BaseBoard class that provides a serial number. However, not all motherboard provide this information (driver code never sets the number).
What is a good, simply way to identify a machine that works consistently on Windows 2000 and newer?

Serial numbers are notorisouly unreliable. You might want to look into the machine SID. Search MSDN for it. I think it's the first 96 bits of the local admin account's SID.

I'm implementing poor man's multithreading and need a way for a progress callback (delegate) to be able to pump the form's message queue so that it can check if the user has checked an "Abort" checkbox, thereby causing an ongoing computation to quit.
In Win32, we used to pump the GUI's message queue using PeekMessage(). What's the appropriate analog in the WinForms world?
Thanks,

Hi Ravi
the analog call of PeekMessage is BeginnInvoke.

HI,
I am having a text file. I will be reading line by line from teh file. Can any one tell me how to move pointer from the current position to previous position(From the current line to previous line).
Example code i am using :-
StreamReader sr = File.OpenText(FILE_NAME);
String input="";
while ((input= sr.ReadLine())!=null)
{
String []strs = input.Split(';');
...
}
Can we move the sr to the previous line?
Plese let me know if there is another way handling the same
Thanks and Regards,
Subbu

Hi!
You'll have to use the Position property of the underlying Stream. Your sr has a property BaseStream you can use for this purpose.

Hi,
I am new to C#. I have a application with 10 winforms. But even after I close the app, the process still runs,ie, I could see the .exe still running in task manager.
how do I solve this. Thanks in advance.

Are you closing your main form ? If you're debugging, does the debugger maintain a connection ? Can you break and see where it's still running ?

How do you close the app? Do you handle the Closing event yourself?
