My approach assumes that the schedule form will always be needed, and makes the allocation attempt only one time. Single allocation results in a performance gain (no overhead for the allocation, and the GC isn't needed), unless the schedule form constructor accepts some sort of parameter from the parent form. At that point, a property or helper function to be called before Show() would still prevent the need to constant reallocate.
I wouldn't use a singleton unless the boss told me to, or unless some other reason caused by the requirements or code forced me to do so.

Why not? I always thought it to be a useful pattern and seems to do similar to what you are saying. The only difference being that it initialises it on first use rather then at the beginning of the use of the form.
Is there a problem with it I should be aware of so I limit using it.

Not at all. I simply have a different way of doing it. Isn't programming fun? 
BTW, my way of doing it enables me to simply call show when I want to see the dialog. I don't have to try allocating it first.

Different minds work in different ways and you can learn from all the different ways
What do you do about GC? what happens if your form has been GC while hidden or do you just put a check in place first?

It can't be GC'd until the parent form is disposed (because the schedule form is a member variable of the parent form), so the schedule form is always available once allocated.

I'm really confused with this issue.
I have an abstract form that derives from Form and has some buttons on it.
I have a private method in the base class that loops through the buttons and tests the visible property (i'm basically going to align all visible buttons evenly form the right). The thing is that all the buttons show as having their visible property as false, does anyone know why this would be?
<br />
btnCancel.Visible = true;<br />
Console.WriteLine(btnCancel.Visible);<br />
shows false
Is this something to do with the form being abstract?
Edit to Add:
I've just realised that when i exit from the method any buttons that were set within the method are showing correctly but the value is still wrong within the abstract class.
Cheers

Damn,
I was trying to change the values of the controls while the form was itself set to Visible = false
Doh!

Hello,
I am using WSE 3.0 to secure webservice with username and password. Username and password are stored in sql database. In order to use the database I derived a class from UsernameTokenManager to override AuthenticateToken method. However, the problem is that password in the database stores md5 hashes of the password. It means that the client should either:
1. send md5 hash of the password using PasswordOption.SendPlainText option
or
2. send plain text password using PasswordOption.SendHashed option but in this case the database should store password in plain text.
Is there any other option that I am missing? I would like to store passwords in database hashed so I guess the only possibility I have is option 1.
Thank you.

a) Google
Or
b) buy a good book

It sounds like you need to be looking at the "In-reply-to" header of incoming messages, and comparing that to the "Message-id" of your outgoing mail. By matching the two and defining a time threshold between send and receive you should be able to detect auto-responders with reasonable accuracy.
It would fair to assume that anything that arrives back within 10-15 minutes of sending would be an auto-responder - well, either that or someone who's way too stressed out, or hopped up on stims 
The only real foreseeable problem is going to be receiving mail servers that delay incoming messages for n minutes/hours (an anti-spamming technique) - if delayed enough it's going to be difficult to ascertain if it's an auto-response or a human response in code..
Google around for "email message headers" for a grounding.

I have a c# assembly, that will be passed to another developer to use as a dll. The other developer does not need to know the workings of the dll, so most of the classes are marked as internal. I have a few public classes that are exposed externally.
Now, i want to add some tests to the assembly (I know they should have been done first!!), but if i add another project to the solution, the test project cannot see the internal classes, so i cant write the tests. How do i get round this without making the classes public, which i dont want to do?

ps, hope this is in the right forum, was not sure if it was here or vs

In .NET 2, you can mark assemblies as [assembly:InternalsVisibleTo("assemblyname...")], so you could use this to tell the assemblies to show internal assemblies to test application.

Thanks
I assume that if a developer that was using this dll, called there project "Tests" for example, they would see everthing as well. Not really a problem as I dont think they would call it Tests. Maybe I should call my test project something obscure
|
|
|
|
|
You can use the public key of your unit test assembly in there as well, so it becomes
[assembly: InternalsVisibleTo("mytestproject, PublicKey="32de3ba45e0a00a1")]

Cheers. It's been a busy couple of months blogging for me. It's helped working alongside Karl Shifflett - he's a coding/article writing machine, and has spurred me on.

That sounds good, How do i find out what the publicKey of my test project is 
|
|
|
|
|
Use sn -Tp on the test dll. This depends on you having strong named the test project of course.
|
|
|
|
|
Thanks, I have just done some reading and am working it out. I think i need to look into strong names more, but you have given me enought to work with.
Thanks for your help, its appreciated
