Iy shouldn't be nessecary to reinstall every time the xml changes.
You could add a FileSystemWatcher to monitor changes in the xml-file and make the service load the updated xml-file.

Your design is wrong. You have to use a FileSystemWatcher, handle it's event and load the XML file when it changes.

I'm building a Windows Installer project using Visual Studio. I've got it set where the app data is installed in the AllUsers folder if the users clicks the "Everyone" radiobutton.
My problem is that when I switch to a non-administrative account, I can start the app but as soon as the program tries to access the AllUsers folder, an "Access denied" exception is thrown! What am I doing wrong?
I've read articles that say your app will be vista compatible if an non-administrative user can access it in XP. (which is what I'm using)
Happy 4th!

In the Windows security model, a non-administrative user is not (or at least should not) be able do anything affecting other users.
You can only read from the AllUsers folder. All settings should be stored in a per-user folder, not in your program's installation folder.

Thanks for the reply. That does shed some light into my problem. However, I am still confused. One of the program features involves writing to a central log when a record is viewed. This log needs to visible for all users. What directory is safe for all types of users?

Can anybody share some knowldge on how to detect un used regisrty key from a system nd deleting those unused keys.
regards,
|
|
|
|

There is no way to tell if a registry key may be used in the future or not.
Don't go deleting registry keys you think might no be in use, you'll only screw things up.
If you want to clean up your registry, go get a tool like CCleaner.
(I once read some good advice regarding the registry. It went something like this. "If you have to be told how to use the registry, you shouldn't be using it."  )

Delete them, if windows or a program breaks, they were not unused. Sorry, that really is the best advice possible.

float * var2;
}Esp;
typedef struct
{
char * var3;
char * var4;
}Real;
__declspec(dllexport) void GetValue(Esp * villa,Real * rud) //when function gets called i added the watch on villa and it shows me that CXX0017:Error:Symbol 'villa' not found
{
rud->var3 = (char*)malloc(50);
memset(rud->var3, 0x00, 50);
rud->var4= (char*)malloc(50);
memset(rud->var4, 0x00, 50);
strcpy(rud->var3, "robhino");
strcpy(rud->var4,"zidane");
unsigned long a=9999;
villa->var1=&a;
float b=15.6f;
villa->var2=&b;

You need to Marshal the IntPtr to int or float.

Hello everyone,
When I use bu or bm to set a breakpoint into a process running C#, there is always error message like -- "Operation not supported by integrated managed debugging."
How to make WinDbg support .Net application debug?
(I made a search to find some similar questions, but not quite helpful.)
thanks in advance,
George

Acording to Wikipedia, there's an extension for debuggin CLR apps.

Thanks Simon!
I have using .load to load the SOS package. And I have tried I can use extension commands like
!threads.
But when I use bu or bm to set a breakpoint, for example, bu Foo (Foo is a function in class FooUtility), there is error message like -- "Operation not supported by integrated managed debugging.
". How to solve it?
regards,
George

Sorry, I've no idea what the problem is. I'm no WinDbg expert.
I'd recommend getting a good guide, like the John Robbins book and starting with a simple app.

Do you have any suggestions for a more specific forum?
