I'm having problems with coding in VB 2010 Express. One of the many errors I am dealing with is the user interface form. It says it's a component, so I have to use it in a form.
View 2 RepliesSo I have decided to learn more about this Invalidate() thing. I decided to simply draw a rectangle where the mouse clicks in the form, for testing.

I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.
View 2 RepliesI would like to make an application where there is no form, only controls, this way theuser can see what they are doing on top of their work. How could I for instance put a textbox on the screen, just like form1, but without it being a parent of form1, almost as if it was form1. Basically form1 is hidden.
View 2 RepliesI am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.

View 3 RepliesI am creating an interface with several textboxes and HTML component and several buttons.But when I drag any textbox onto the existing form they line up vertically one under the another or they attach directly together on the same row. I want to be able to drag and drop and place these as well as the HTML component wherever I need on the form. In VB6 I simply selected what I needed and placed it with ease. Can someone tell me what I need to do gain this simple freedom in vb.net

View 1 RepliesI am working in vb2008.TableAdapterManagers are a new feature in vs 2008 and I would like to understand how to use them properly.I have about 30 tables in my database that are unique to themselves and donot link to other tables.I have created a dataset.xsd in my solution and dragged in my database tables of interest.A unique datatableadapter has been identified in the dataset1.xsd for each datatable.Rather than using the identified datatableadapter for each datatable operation, should I be using the dataadaptermanager for each unique table?
View 1 RepliesI am working on a user control. Embedded in my user control is another user control. All of a sudden while programming some simple stuff I get an "out of memory error message". I can no longer load my project (after reboots etc.). I start a new project, copy the control.vb files into a new project folder.. add then add the control to the new project. Ican view the design and the code of the control. When I attempt to drag the control onto another control in the same project I get an error message
"Failed to create component... 'system.outofmemoryexception. Out of memory".
I have 2 forms main_frm and copying_frm. In main_frm, there is a list view that is populated with file names. The user then clicks save and all the files in the list are copied to a folder that they choose using a folder browser dialog. When this happens, I do copying_frm.ShowDialog() to display the copying_frm. The copying_frm contains a progress bar and a cancel button. I can get the progress bar to indicate how much has been copied. But that freezes up the application. To get around this, I create a new thread (called copyingThread) that copies the files. When that thread runs though, it can't access the waitingList_lvw in main_frm. For example, in the function that the copyingThread executes, if I have this line of code: MsgBox(main_frm.waitingList_lvw.Items.Count.ToString()) the result is 0. Also, I don't get any errors and no files are copied. How do I access waitingList_lvw in main_frm from a thread called copyThread that was created in copying_frm?
View 6 RepliesI have an interface class (IUser) which is the interface of class User. Now, i want to put these into an IList but am confused as to how i should declare the IList:Dim userList As IList(Of IUser) = New List(Of IUser) Dim userList As IList(Of User) = New List(Of User) Dim userList As IList(Of IUser) = New List(Of User) Dim userList As IList(Of User) = New List(Of IUser) when instantiating should you always use its implementation; and when using it as a type use its interface?
And when im creating a new user should i use: Dim myUser as IUser = new User?

View 2 Repliesi have few questions about the user interface when working with a VS setup project
1. i have added a Checkboxes dialog, i have 3 checkboxes they are used to select upon 3 tools to be installed, so during the progress of the instilation, how should i let the project know which of the 3 tools was selected ? (i hope i was clear)
2. a bit of silly question - is it possible to edit something in a dialog ? like in my case in the "finished" dialog my customer didnt like the the end button is named "close" and he wants it to be named "Finish"
finally, this is an extra non programing but it would be good if i was able to find an answere :P, when i plug a USB in the computer it opens the autoplay, and i have my instilation file in the USB (it will be distributed on a USB rather than a CD), so i want to add to the autoplay a button that runs the instilation file

View 14 RepliesI have a generic question regarding file paths and user interfaces. I am trying to build a user-interface to accommodate various file locations. I typically build interfaces which deal with files on drives. As such, I use a directory tree for this. I usually work with files on local drives. However if I wanted to ensure that all file locations were dealt with I would want to ensure that I was accommodating files in all drives (local, network, mappped etc.). I am assuming that the treeview would support all of these drive option.
However if the files are on a sharepoint site or in some other type of enterprise content system, then am I correct to assume that these file paths will be URLs? If so, then am I correct to assume that a directory tree is not the correct control to use for these locations? Should I be providing a textbox to the user and prompting them to enter this URL? Or is it better to have the URL loaded into a ListView or ListBox (i.e. "My Connections") and then provide these as options via a dropdown box. I am trying to picture a typical user interface. Is it a directory tree AND a text box/dropdown box.
Basically the question is, Why are NONE of the changes I've been making in the designer reflecting on the program when it runs ?'none' is in bold because I've tried moving everything around and nothing seems to be affecting it, it's like it's reading from a different design file, I tried reloading the project and that did nothing, and none of my code affects position of any items on the form (way too much to post it all)
