Heath, here's a question for you. Does the /quiet switch tip also work for VS 2003 SP1?
|
|

Off the top of my head, no. That uses an older wrapper that doesn't support (because they didn't exist when it was written) the standard Microsoft command-line switches for update packages. You can search my blog for details.

OK. Well I've installed VS 2003 SP1 at work and it wasn't too bad. I used the /quiet trick for VS 2005 SP1. Reason I ask is because at some stage I will be applying the SPs to my home versions.

At the microsoft launch event, the presenters said that the .NET framework 3.0 is the same as .NET 2.0 but it includes WPF, WCF, and CardSpace (might be missing a category, but still). Your applications should work fine with .NET 3.0, but if you want to take advantage of WPF then you will need to rewrite the GUI aspect of your applications using the .NET 3.0 tools. But the source code change from .NET 2.0 to .NET 3.0 should not change.

Thats what I thought, but always better to be sure 
I think recreating the GUI is not an option at this stage - it's almost complete as is, and the project deadline is looming ever closer (as always). This is something I will look into further in the future, as my application is using a layered architecture it should just be a case of replacing the GUI if required.
Thanks for your help guys

Hi,
Using pdflib library in C# I have created a pdf file which is
protected using owner password .Different options are disallowed like
print, copy contents etc. Things were working very fine untill i came
to know about some password crackers which could easily crack the
file , eliminating the password , thus making it possible for
operations like printing, copy etc .
The study showed that using user password as well will make the file
strong enough to be decrypted ,but "user password" is not a solution
in my case .
The code which actually creates a pdf file using pdflib is as under :
PDFLib obj = new PDFLib();
obj.begin_document(FileName, "masterpassword=23wdlm3ldjwld4w
permission={noprint}");
Now i wonder even that the file is encrypted using 128-bit
encryption , how a password cracker can retrieve that stored password
form the encrypted file .What operation is performed by the cracker to
remove the password and making the file accessible for all options .
Can any one please help me in this ....
Regards,
Madni

You can encrypt the file all you want, it won't help you. Your problem is that in order to use it, it has to be decrypted at some point before it's used. This is where the hacker is going to get his hands on the file and just do what he did before.
There is no way you can 100% protect the file. You can only slow the hacker down...

Even if you were to handle encryption on the server where every users is given a separate, licensed private key to decrypt, the user in your project would only need to bypass the upload for the server to encrypt the document. So long as anything executes on the clients' machines, you can't entirely prevent them from doing anything to your code. Dave's absolutely right: you can only slow them down.
Take recent events. Protection for HD-DVD and Blu-ray were both cracked by a good debugger finding the private keys stashed in an application that needed them to decrypt. They didn't hide them well enough. All other apps simply hide or obfuscate their keys. It's not impossible to get them.
If you read Bruce Scheier's wonder "Applied Cryptography", it reads (and is famous for stating) that givne infinite time and resources, anything is crackable; it's only a question of encryption strength vs. information worth that dictates when a cracker will get the information they want (or if they even bother).
Note that a distributed approach to solving your problem is about the best you can do. So long as each client gets their own decryption key (or you can developed a shared decryption for group management, which some DRM enables currently) you can at least revoke it on a per-person or per-group basis. A would-be cracker would need an individual's decryption keys or decipher the message the hard way without them.

Hi all,
I've got a little question about system colours and xp themes.
Most objects in windows xp change colour when you change theme. In the .Net framework you have the SystemColors enumeration which you can use for objects to be appropriatly coloured with each theme.
However, i've noticed there are some colours that aren't represented in this enumeration. For example, if you right click on a folder and go to properties, then to the customize tab, there are several group boxes with text on them. In the xp-default and silver color schemes, the text is blue, but change back to windows classic theme, and the text is black.
I've checked every system colour in the enumeration, and not a single colour is blue in both the xp-default scheme and the silver scheme.
I've looked around on google but can't find anything relating to this. Does anyone know what colours Windows is using. Obviously, i've considered the option of manually defining the colours, and altering them when the user changes the colour scheme, but there must be a simpler way than this.

You should be able to do a print screen and use a program like Paint Shop Pro or Photoshop to get the specific color of the pixels in the text.
It sounds like you may have to manually alter the colors used, I believe you can listen in on theme change events in Windows XP to tell when a theme has changed.

Visual themes are a different sort of beast. There are themes installed on your system that define way more categories of representations than SystemColors, and if you want to use themes you have to owner-draw these on your controls yourself. .NET 2.0 makes this fairly easy for controls in the base class library (BCL). For your Windows Forms application's entry point, use the Application.EnableVisualStyles() method like so:
class Application
{
static void Main(string[] args)
{
Application.EnableVisualStyles();
Application.DoEvents();
Application.Run(new MainForm());
}
}If you want to draw themed text, borders, etc., on your owner-drawn controls, read Rendering Controls with Visual Styles[^] and Custom Control Painting and Rendering[^].

 Hello!
Im trying to write a deployment project in VS.net 2005.
What Im trying to do is this.
Take the target installation path and write this string value to the registry.
I just cant figure out how to do this. I know how to write to the registry, but somehow I need to get the target path and write this parameter to the registry.
Very thankfull for any help.

The VS deployment projects aren't very flexible. You might be better off using WiX[^]. That said, you can use [TARGETDIR] for your registry value in most cases. If you're trying to write the exact location of a file you can use the notation [#filekey] but that where things get difficult, since the VS.NET deployment projects don't show you the component, file, registry, etc. key names (the deployment projects compile into .msi files, which are relational databases processed by Windows Installer).

Hello!
Thanks for your answer!
I found out [TARGETDIR] right after I posted 
What is WiX and where can I find it?
Best regards!

It looks promissing I must say!
Does this integrate into VS.net?

If you create your own project installer (System.Configuration.Install.Installer), you can easily get the install path by just using reflection on the executing assembly. Here is some code I use to do this in my installer:
System.Reflection.Assembly asm = System.Reflection.Assembly.GetExecutingAssembly();
string baseAppDir = (new System.IO.FileInfo( asm.Location )).DirectoryName;
RegistryKey softwareKey = Microsoft.Win32.Registry.LocalMachine
.OpenSubKey( "Software", true )
.OpenSubKey( "Company Name", true )
.OpenSubKey( "Application Name", true );
softwareKey.SetValue( "InstallLocation", configFilepath );
Keep in mind that I added a registry value in setup project that creates the HKLM\Software\Company Name\Application Name\InstallLocation key with some default or empty value. The setup project actually creates the keys you specified in the registry editor part of the setup project before it calls your code in the Installer class.
