I'm trying to develop an application which changes wallpaper automatically at an interval of my choice.
I'm using the WinAPI.SystemParametersInfo() method. It works fine when running in a simple application but doesn't work anymore when running in a Windows service.
Does anyone know why?
Thanks

A service was mot a good choice for this application. It should stay as an application that runs from the users Startup folder. This is why:
The wallpaper is a user-specific settings, meaning that each user has their own preference for this setting. The setting, if changed by one user, is not applied to all other users on the machine, logged in or not.
Next, on Windows XP, you can have multiple people logged in at the same time, though you can only have one session active at a time.
Now, a windows service doesn't run in the context of the user(s) that is lgged in. In normally runs under the context of Local System. Further, the services each have their own desktop, or more specifically, no VISIBLE desktop. So, when your service is setting the wallpaper, it's actually doing on a desktop that you can't see.
Having said all that, it is possible to have a service interact with the desktop that's currently logged in/active. In the Service Control Manager (Administrative Tools), find your service and get the properties on it. Find the little check box that says "Allow interact with desktop". Now, this is no way guarantees that the SystemParametersInfo call will work. But if it does, the service will be changeing the wall paper for ANY user that logs in, regardless if they want it to or not. This is why it's best to leave it as a normal Windows Application and let it run out of the users Startup folder.

I agree with what Dave said. Webshots for example runs an instance on every user that wants to use the program.

Is there a way to change the forecolor/fontface/fontstyle of the column headers in a DataGrid? Maybe even the background color?
Thanks,

Hallo,
for launching my program when windows starts, i added an entry to
HKEY_LOCALE_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run in my setup-project.
This works fine, but if the program is loaded, if have to find out if this
was done by the user or by the operating system.
Is there a way to find out?
Thanks for your help,
Björn

Since there is no difference between the OS launching the app and a user launching the app, no.
When an application is launched out of the Run key, it is actually a request made by the Shell, to the Loader in the OS. When a user clicks on an icon in Explorer, the exact same thing happens. The Shell makes that same request to the Loader, on behalf of the user (or in othjer words, in the security context of the user).
So, no, there is no way to tell the difference...

Hi,
Is there any method to parse a string in the same way of sscanf?
Suppose you have a string with Number1= 3 Number2 =2.58874. I can do this by hand, like finding the = sign and then use Int32.Parse() and Double.Parse() but since I have a lot of strings with a lot of different formats this does't seem to be a good way. 
So is there any better way to do this?
Thanks!

Actually, no. You can use regular expressions to ease things a bit, but you'll still need to parse it by yourself.
HTH.

object oEndOfDoc = "\\StartOfDoc";
object oCurrentCell="\\Cell" ;
Word.ApplicationClass oWordApp = new Word.ApplicationClass();
try

oWordDoc.Activate();
oWordApp.Selection.TypeParagraph();
oWordDoc.Content.Delete(ref missing,ref missing);
Word.Table oTable;
Word.Range wrdRng =oWordDoc.Bookmarks.Item(ref oEndOfDoc).Range;
oTable = oWordDoc.Tables.Add(wrdRng, DataGrid1.Items.Count, 5, ref missing, ref missing);
oTable.Range.ParagraphFormat.SpaceAfter = 6;
int i,j;

I personally haven't worked with Word automation that much. You might get some luck here, but ms newsgroups are probably a better place for this question. See: http://msdn.microsoft.com/newsgroups/[^]

How Do I Convert Char[] to string?
One way to do this is to create a new String object by using the constructor public String(char[] value)[^] of the String Class[^]. For example:
char[] CharArray = new char[12] {'H', 'e', 'l', 'l', 'o', ' ',
'W', 'o', 'r', 'l', 'd', '!'};
string Foo = new string(CharArray);
MessageBox.Show(Foo);

Hello machocr,
Please note that a string in C# may not actually be an array of characters. That is, it is not guarenteed to be contiguous in memory.
An array (of any type) in C# -will- be contiguous in memory.

AFAIK, you can't.

Have you considered that licensing in .NET is too easy to break?

Hi all.
Is there a way to check if a file has been digitally signed and has attached digital certificate and then if so extract it so it can be used on the code.
I know there is a tool called secutil. How can I use it from command line?
Any other ideas? Please help.

I'm not sure if I've really understood what you want to do. Maybe you can explain it a little further?

Yes, and if the files you want to check are indeed assemblies secutil should be the right tool to extract the public key. You can find the reference on MSDN (see Secutil Tool (Secutil.exe)[^]).
Best regards

I need to check if a file is an assembly and if so need to check if it has attached a digital certificate. then I need to use the contents of the certificate in my C# code: basically need to copy the fingerprint.
How can I call Secutil from within my C# code. I have no idea how to do that?
Cheers,
izabela
