Hi all. I need to find a signature block in a scanned document. I can create the document so I can put a box around the signature or mark it in some way. I just don't know how to find it. I don't think I can depend on it always being in the same spot. Any ideas?

Depends on what a 'signature block' is. Obviously, because it's scanned, you can't depend on it being pixel for pixel exactly what you expect, or even to be rotated 100% correctly. You'll need to do some fairly complex pattern matching. Edge detection would be a good place to start, to simplify the image you're dealing with, assuming this won't lose detail that you need to find.

Hi all.
I'm not sure if this is the right forum for this. If it's not, I'm truly sorry. I have a couple of questions regarding Whidbey (VS.NET 2005) Beta 2.
1. Is it safe to install it on my production machine? Working in a Virtual PC is a PITA. It would be installed side by side with VS.NET 2003. Horror stories? Tips and tricks regarding this?
2. Say I reference an assembly (ie: 3rd party component) that was compiled with .NET 1.1 in a .NET 2.0 project. Will this 1.1 assembly run against the 1.1 or 2.0 framework? Is it safe to reference v1.1 assemblies?
3. When I install the .NET Framework 2.0 on a clean machine (ie: no .NET 1.x installed), does it also install v1.0 and v1.1 of the framework? Say the answer to question #2 is that it runs against version 1.1 of the framework, am I required to install BOTH versions of the framework on my customers machines?
Thanks a lot for your help!

1: I am doing this ,and it's bretty fine  .
2: It will convert it to the appropirate version and use the .Net 2.0 to run it. AS FOR EXAMPLE : (Any .NET 1.0 application runs clearly on .NET 1.1).
3: No,2.0 will be enough to run any VS2005 application .

Hi,
Thanks for your answers.
However, I'm not sure you understood question 2 and 3 correctly. I meant, if I reference a DLL assembly that was compiled with version 1.1 of the framework in a 2.0 application, will the DLL run against v1.1 or v2.0?
Thanks!

That will depend on if your assembly was specifically built to target 1.1. By default, it targets the most recent framework version on the machine, I believe, so regardless of if it's referenced in your project, it will run under 2.0 on a 2.0 installed machine. You can set it to build so it requires 1.1, though, and then it would run under 1.1, because you told it to.

I've just been to a Microsoft MVP conference where my focus was on Whidbey sessions. Microsoft say it will be fine when they release it, and should be fine now, but they don't recommend it. I personally run it next to 2003 on a non dev machine ( a notebook I use to play around with stuff ). I would never install it on a production machine while it is in beta.
The whole point of the framework targetting is that you can explicitly target a framework version, and then it will always use that version.
I don't believe it installs 1.0 and 1.1, no. Yes, if you have a component that requires 1.1 for some reason, you'll need to install both on a client machine. If you wrote the component, run your regression tests against a build using the new compiler, and then move to 2.0. If you don't have regression tests, have some next time you build something. 
You can get a licence from microsoft to distribute 2.0 code and the framework, but it requires you to replace all installs of the beta framework in the wild with the full version within months of the release date. I wouldn't do that unless you have to.

Thanks for that info Christian!
Our release is set for October or around that time. 2.0 final should be right around the corner by then.
What's the lastest temptative release date for .NET 2.0? Do you know? Of course, "nobody knows for sure", but what are they aiming for? Can we expect it for oct/nov you think?
There's a running joke that says December 35, 2005
Have a good evening!

I believe they were saying we will definately have it by the end of the year. The overall thing is, Microsoft won't release it until it is ready. I am using it at home now ( I am writing code libraries on it that will compile under 1.1, so I can learn the new IDE without relying on it ), and I'd say it still needs some work, I've reported a couple of bugs.
When you install it, if you're using C#, type for and hit tab twice. That's called a code snippet, they are very cool.

I heard Beta 2 is very robust but needs speed optimization and stuff like that. What's your "bottom line" on VS.NET 2B2?

I've crashed it a couple of times, when I first ran it, which gave a bad impression. It's been stable for me for a while now though. It's certainly slow, and there are certainly still bugs to fix. That's why it's a beta

Hi,
I am just starting with .NET programming and am trying to figure out the implementation of Data Access block provided by the Microsoft Enterprise Library. How does one provide connection string and access the database using the Library?
Thanks

There is a configuration program installed with the library. Run the configuration program and configure the application blocks you are going to use in your program. It creates entries in the app.config or web.config, and adds another config file for your application. You put both of these files in your project. Thats it.

Hi!
If I have a static variable in a class in a class library, will it be shared among all programs that use the same class library on the same computer, or will every program have it's own?
public class x
{
public static int y = 0;
}
BR

Every instance of the class will have it's own value.
What are you trying to do?

Static variables are static within their appdomains. So two appdomains within the same process can have two different values.

It is true, but there is a way to modify such behavior.
If you mark your variable with ThreadStaticAttribute then this variable will be unique for thread.

Every program that is running on your computer has its own Process. The operating system creates the process which your program will run. Each process has its own stack and heap and depending on how many threads you are running, and the operating system every thread in your program will have its own stack. This is true no matter what DLLs are being used by your program. DLLs or shared libraries do not have their own stack or heap.

Does anyone know how to send an object through TCP Socket?
Or how can I convert an object to a byte array in .NET Compact Framework?
Thanks a lot!!!
|
|
|
|
|
Try .Net Remoting (look it up on msdn and there are lots of books). The object must be serilizable first so don't try to move a datatable or a hashtable.
|
|
|
|
|
But if I am using .NET Compact Framework, how can I do so? It is because there is no .NET remoting in .NET Compact Framework. Thanks a lot for your reply

You can use binary serialization to write the object out as a binary stream and reconstruct it at the other end.
private void Serialize(NetworkStream stream, object obj)
{
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, obj);
}
private object Deserialize(NetworkStream stream)
{
BinaryFormatter formatter = new BinaryFormatter();
return (YourTypeHere) formatter.Deserialize(stream);
}
