• Mantorok Events inserted at the cursor

  Hi All, Does anyone know of an option setting that makes the selected event insert at the cursor, when in the code window Presently, when I select "Class Name" and then "Method Name" from the two dropdowns at the top of the code editing window, the event *seems* to insert itself randomly. ("Class Name" and "Method Name" are the tooltips) Thanks, Carl Hi Carl, There is no such option to make the selected event insert at the specified location of the cursor. Generally events are inserted in an alphabatical order with some exceptions like the if the current order of events alreday in the code window is not alphabatically sorted then it try to pick the close ...Show All

• Caolan ODomhnaill How to pass a dictionary(of) to a generic procedure?

  I have this procedure header: Public Function Register( ByVal dict As Object , ByVal ElementName As String ) As Boolean The "object" is always a Dictionary(Of String, something). The something is a business class. There is a limited number of possibilities, so I could constrain them, but I'd rather not. I want to write something like the following but I can't get any variation to even compile: ' Public Function Register(Of t As {IDictionary(Of String, Dataface.DataSource), IDictionary(Of String, Dataface.AConnection)})(ByVal col As t) As Boolean ' Public Function Register(Of t As Dictionary(Of String, Dataface.BaseClass) (ByVal col As t) As Boolean In the body, I want to be able to write co ...Show All

Here is just a little code: Private Sub StartTasks() ' Create And Show Loading Bar Dim frmLoading as new LoadingBar frmLoading.Show() ' Start To Do Time Consuming Tasks ...Show All

• tyler2424 Shared interface member

  Why can't interface methods be declared Shared in VB I have a controllerFactory interface that is used in a number of apps to dispense app sepcific controller classes for use in an app neutral framework. Currently I have to create an instance of the controller factory classes to invoke the GetController methods. Ideally I'd like to make this method shared and invoke it without creating an instance of the Factory. If I try to mark the implementation shared then Visual Studio shows the error "methods or events that implement interface members cannot be shared". If I mark the interface method as shared the error message is "'Shared' is not valid on an interface method declaration". Here's the interface definition: ...Show All

I am developing a travel agent booking system that allows a customer to register and book themselves and multiple other people to go on holiday.

This is all to be stored to a database (I have this bit covered) What I am asking is how would you go about making a summery screen display the selections and costs of each traveller.

• Stefan van der Merwe Types that cannot be Converted from VB6 to .Net

  Hi all, I have an Interface named "IMyInterface" declared in VB6. And I have a user control project in VB6, this user control implements the Interface "IMyInterface". Now I want to use the user control developed in VB6 in my new .Net Project. So I have added the reference of the VB6 user control in the .Net project, by the way .Net IDE creted the Interop dlls. Now I want to make a call on the VB6 user control through the IMyInterface as my VB6 user control implements the Interface. This IMyInterface has 10 functions, some of them returns basic data types and some of them returns structure/class types.

• anydobbo Disable "Move" for my form

  I am writing Windows Application with VB.NET. I would like to have my form occupying the whole screen and disallow the user from resizing it and moving it. I successfully coded it such that the form didn't move when the user dragged the title bar. It was what I wanted but it was not so perfect. When I press ALT+SPACE, a context menu popped up and this menu contains a menu item called "Move". I wanted to disable this menu item "Move" such that it only showed as a gray text instead of a black text. Which function to call Here's an example form that implements a custom TitleBar. One issue is that the Text property can't be used and therefore the TaskBar button has no caption. You could c ...Show All

• Tall Dude Unsigned Arithmetic and overflows

  I've had this discussion before with unint64s. Setting what would normally be the sign bit causes an overflow. Now I'm seeing this in unint32s. Dim a As UInt32 = System.Drawing.Color.Black.ToArgb will cause and overflow. Dim a as Uint32 = now.ticks and &hFFFFFFFF will cause an overflow depending in the time. This should not be. What it means effectively is the UInt32 is actually UInt31. No, it does not mean that UInt32 is actualy UInt31. The Ticks property of DateTime is Long and &hFFFFFFFF is an Integer constant. To apply the And operator the compiler extends &hFFFFFFFF to Long, that is to &hFFFFFFFFFFFFFFFF and does the And. Obviously you'll get a 64 bit value mots of the time that will never ...Show All
