I created a web service that authenticates a user based on User/ID.
When the user does not authenticate, I would like to display a login form.
Can a my web service return a windows.forms.form object.
I have imported a form class into the web service project.
I created a web method that instantiates it and returns it.
When I invoke the method It fails.

It could, but it is NOT Web Service friendly. Your Web Service should be self contained and use NO user interface what-so-ever. This would allow your service to be used by either a Web Application OR a Windows Forms app without any changes to the service or regard to the type of application calling it.
Since a Web Service is usually stateless, using a User Name and Password is not really a good idea, but it is possible.
Your application would have to supply a user interface that gathers the username and password. The Web Service would expose a method that authenticates that information against a credentials database and establishes a session tracking record in a second database. This session tracker would generate a token, possibly a GUID, and return that token to the client. For each and every subsequent call to the Web Service, each method would take that token as an argument and see if it exists in the session database. If not or if the session expired, the call would be denied and return some kind of custom authentication exception that the application would have to deal with. If so, the call would be processed as normal, then the session database record updated with a new data/time value that would keep the session record alive. The session database would scan the session records, say every minute, and timeout (kill off) the records that have expired in, say, the last 20 minutes.
Every method call you write in your service would have to update the record of the session token it gets! This way, someone can't login to your service and just sit there all day, not doing anything with it.

Hi community,
I want that my Form acts on the OnSystemColorsChanged event. Therefor I overrides the OnSystemColorsChanged methode like the following:
Protected Overrides Sub OnSystemColorsChanged(ByVal e As System.EventArgs)
Messagebox.Show("SystemColors have changed!")
Me.OnSystemColorsChanged(e)
End Sub
The result is fatal. The system hangs. When I change the order like:
Protected Overrides Sub OnSystemColorsChanged(ByVal e As System.EventArgs)
Me.OnSystemColorsChanged(e)
Messagebox.Show("SystemColors have changed!")
End Sub
The Messagebox woun't be shown !?
Where is the problem????
Thanks in advance

Wouldn't you be better to use MyBase rather than Me?

Accordint to MSDN ("OnSystemColorsChanged (inherited from Control)") it is inherited from System.Windows.Forms.Control, so even although the Form class doesn't do anything additional with it, there is some version already in your class heirarchy that you are overriding from.

In VB6 we can create an array of database connection like
dim cnObj() as ADODB.Connection
In VB.NET it is not possible. Is it possible in VBExpress? If so how. while writing code the compiler does not give error. Even while redimensioning no error. But when assigning a new connection to a redimensioned new array of system.data.oledb.oledbconnection, i get an error "Array dimension is not available" or similar error.
What is the problem here or does VBExpress support connection array? Is it possible to keep these connections in a collection?
Thanks

It is possible, but why would you want to? Best practice is to open a connection just long enough to do whatever work you need, like setup a DataReader (which will close it's connection upon reading the dataset), update a table, or call a stored procedure, then close it when it's not needed for the current operation anymore. Keeping a connection open a poor practice because they are expensive resources to have open on the server occupying a connection license and holding on to resources.
VB.NET and VB.NET Express are the exact same language. You might want to look into using a collection instead of an array. What does the code look like that your having problems with?

Well i do know it is expensive to hold memory with multiple connections. Indeed stinky piece... Consider an auditor or a CEO or a top management person of an organization having a system which can connect to all systems simultaneously [Production status from SCADA/PLC, Finance status from AS400, User info from Exchange server, Raw Material info from Mainframe data, Customer info from Biztalk etc] all in one application, compare them [technically in one dataset but multiple connections].... Exactly this is what i did and my system worked perfectly when it was done in VB6(multiple connections stufffff) but not in DOTNET... may it be array or collection....
Hope that you got what i'm trying to tell. This is not the competitive techi stuff to prove something but used or in high need in enterprise level...

So? You still don't need an array of connections for this!
In proper modular programming s own class(estyle, each of these systems would have its own class(es) that manage the fetching of data from that system. Again, the proper method is to open the connection, perform the data transaction, then close the connection. Keeping the connection open only as long as is required to complete the transaction.
BTW: Creating an array of connections IS possible, but no-one does this because it's never necessessary. Unless your writing your own connection pooling algorithm, anyway.

Hi Guru's,
Let's say I have made a Question Dialog which has 2 buttons: a Yes and a No button. When a user clicks on the main form 'Delete file' button the question dialog is called like this: frmQuestionDialog.show vbmodal.
How can i know after calling the .show which button Yes/no they have pressed at the question dialog?
Best regards,
Jens

Simply create a property on your Question Dialog form, which you will set with a value telling what button was selected by the user. Read the property just after calling .show method.
Best wishes,
Maciek

Your question would be better handled in the Embedded/Mobile Forum[^]. The information your asking is specific to Mobile developement, not Visual Basic.NET.

I am working on a project that consists of 4 forms. It starts with a main, which I have added a "Public Shared" variable for the title of all forms. This part works. It then branches off into 2 forms, then from these it goes to 1 form. I need to be able to take a variable from the two forms and pass it to the 3rd form and a variable from the 1st to the 3rd. Here is an example.
form 1
title - to all forms
user - to form 4
form 2
type - to form 4
form 3
type - to form 4
Any and all help is greatly appriciated.

Hi -
I've had some success adding public methods to the forms for passing information around, but it's been a while. I think the secret is that all of the forms can see main, but forms other than main might not be able to see each other. So to pass data from form2 to form3 it might be necessary for form2 to call a method in main which in turn sets the data in form3. Just make sure you don't try to call a method in a form before that form is instantiated or you'll get null pointer errors.
Hope this helps...
