In an ideal world, tests should be able to successfully run independently of their ordering.
However, this is the real world. If you have a bunch that you really really absolutely have to run in order, then I would say to make a test that just calls the other tests, in order.
Alternatively, create Setup and Teardown subs that prepare the way for (and clean up after) each test.

Hi
I'm trying to get webrequest in BeforeNavigate2Event, and save it, but it seems that the postData object is not the same object what explorer actually send. In BeforeNavigate2 Event i save all objects (url,postData,headers) and than call the navigate2 method with those objects but it doesn't browse the same page. If i make the postData manually (string -> byte[]), there is no problem at all. I also looked the both byte arrays, they are different. and i decoded the explorers postData to string, it's the same string what i manually wrote. Why the two byte array are different and how can i get the actual postData?
thanks

What OS are you using? With XP, I've never encountered this problem. In fact, I have the opposite problem--when I take my laptop somewhere, many apps end up opening up off-screen because that's where the they were last on the now disconnected second monitor!

well, i´m using WinXP,SP2 German.but it should also work on win2kpro german.
but normally displays won´t get disconnected.
is it possible to select explicitely which of the connected displays to use showing forms?
i know its possible to enumerate connected displays via native call
EnumDisplayMonitors(NULL, NULL, MyInfoEnumProc, 0);
but i didn´t get it to work by now via native calls.
i wonder if there is possibility to do it with just .NET

I'm not aware of any .NET classes that deal with multiple monitors.
You might want to look at this though:
http://www.realtimesoft.com/ultramon/[^]
It has [edit] an SDK with [/edit] source code, but not .NET, unless someone has ported it. Still, it might give you some information as to the underlying API's and tricks to use.

Hi
I have a form with a web browser control in it. I want to receive dragdrop notification when I drag things onto the from (mainly files from the desktop), however the browser control seems to be blocking the notifications. If a hold the icon over the borders of the form and title bar, I get notified, but not when the browser is in the way.
How can I get notified no matter where I'm holding the item in the form?

I have a main form that has an Apply button that is normally in disablled state, used to save the settings in the main form and another form called Option form. The Option form is used to set some other variables.
When I open Option form and change any thing on it, I want the change to reflect in main form and make the Apply button enable.
How to do this?
Please guide.

hi,
Change the modifiers property of your button which is there in main form to Public.
After this you can access the button to any other form using the instance of main form.

hi,
A small senario. Suppose if you want to check the status (whether button is is disabled or not) of control in mainfrom you can go ahead with this idea.
otherwise please let me know what you want exactly.

Thanks for the reply
I would like to enable the Apply button in the main form as soon as I change the status of any control in the Option form. e.g. I have a check box in the Option form, if I click it and change the status from checked to unchecked or the other way, I would like to enable the Apply button in mail form so that is I click it, I will do some other processing of storing the status of the controls.
Sorry for not being acurate in stating the problem.

You are going to have some limitations to doing this. Both forms must be in the same message thread (so your first form must launch the second form on the same thread).
To access data in a partner form you need to do a few things.
Situation : You have Form A. It will create Form B. Form B must change status in Form A.
Answer: Modify your constructor in Form B to take its' parent as a parameter. Then in Form A pass (this) in the creation logic.
If it is the reverse (Form A creates and modifies Form B) no special constructor is needed since you already have the form object at your disposal.
Now the second part of it: accessing the button, label, whatever. To follow proper coding convention, you would add an accessor to the form for each field you want to expose access. Your accessor would provide both a getter and setter.
One other approach is to implement an event bubbler. Tie each form together with your own event much like the Observer Pattern. Then when a change needs to occur, the observer raises the event, which can bubble up through the various forms, and each form can react to the event accordingly.
If your forms are in different application domains, then you would probably want some type of remote notification system (much more complex).

thank you very much for the comprehensive reply.
my forms fit in first situation, they are in one thread only. in the main form i have Option button, on its click event Option form is created.
let me explain a bit more about what am i up to.
the main form is customized Print dialog, its upper half is like a normal print dialog and lower half is divided in two parts, left part is having a tree view and right part is kept for displaying user controls associated with the three node, each one is linked with the tag property of the tree view node. thus i have near about 115 controls ( check boxes, radio buttons, numeric up-down controls and combo boxes ). besides a few more in option form.
i have an Apply button to save the status of all controls. its normally in disable state and have to make it enable as soon as any controls status is changed, and have to again disable the Apply button is the user comes back to earlier status. how to keep track of all the controls is the big question for me. besides the earlier problem.
i was also thinking of passing 'this' in the constructor of Option form, but i read some where that parameterized form constructors are not advisable, thats why i wanted to have experts comments.
i understood the concept of getter-setter in your reply but being a new comer not able to understand the concept of an event bubbler. please explain it a bit more.
regards

Okay -- here is an example of a bubble-up architecture:
I have a control which contains a treenode and a display area.
The 'display area' will have different custom controls loaded based on the type of data selected in the tree. This control can exist in the main form or can exist as a dialog by itself in your applications.
The parent form that contains this control has the job of opening the file. This event is exposed for anyone interested. It loads a custom control which can have access to the NewFileEvent from the parent form. This second custom control lets the user select filters from dropdown boxes. It raises the NewFilterEvent to its children and the NewFileEvent. So it has code like this:
parent.NewFileEvent += new NewFileHandler(NewFileBubbler);
...
private void NewFileHandler(object sender, NewFileArgs e)
{
if (this.NewFileEvent != null)
NewFileEvent(sender, e);
}
Each subsequent control that gets loaded may contain hundreds of controls but they pick and choose which events they are interested in. That initial control I spoke of wants to know when a new file is loaded and when a new filter is set. If you write a program that uses my control, you need to provide your own events using my defined event arguements to pass the new data, new file location, new filters, whatever.
The end result is the parent has no idea what is loaded in it. The control it loads loads other controls which load their controls, which load their controls. Events bubble up from the parent to the top-most control.
This handles a situation where you want all of the controls in the list to know that a state has changed. It sounds, though, like you want the reverse. You want to know when one of the controls changes. This sounds like you may want the Observer Pattern. It has an observer that acts as a go-between between the data (control state) and the observers (the items that have to react to that change).
Start here[^] to find out about the Observer Pattern and see if that helps your situation.

Just wondering how to hide a property of an interface in a sub-class?
For example in .net framework,
OracleCommand implements IDbCommand, but OracleCommand doesn't have the CommandTimeout property where IDbCommand has.
IDbCommand has<br />
int CommandTimeout {get; set;}<br />
<br />
<br />
public class OracleCommand : IDbCommand<br />
try using OracleCommand.CommandTimeout gives an compile error.
How???

You must cast OracleCommand to IDbCommand.
Hide interface property you can do in this way
public class MyCommand : IDbCommand
{
...
int IDbCommand.CommandTimeout
{
get
{
...
}
set
{
....
}
}
}

I've ravaged through MSDN and the KB articles and I am still not sure what is the problem here. cmd is a string for a validated and well formed email address.
Thanks for any suggestions or help.
