It seems that the autosize columns will only make them bigger. For example, if I have a DGV that fills most of the form and then only three small columns are loaded, there is a whole bunch of darkgrey empty space. Is there any way to snap the side of the DGV to the actual data?

Long time since I was active on this forum, but I recently picked up VB.NET again. I'm working with VS 2010 Express now, and I want to create a little app that resides on the side of my screen (about 40px wide), to collect data.
I've seen this program, Trillian, 'docking' to the right side of my screen, thereby making the maximized size of all windows just as much as the space left of the application window. In other words, even if I maximize other programs, the Trillian application stays visible at all times, on the right side of my screen.
Now I was wondering, is there any similar effect possible with VB.NET?

I need to send back the id, the old value from _1 and the new value from _0 back to the server. What is the best way to format this data so I can easily extract the data from the server side so I can easily email someone for example to let them know which textboxes have changed, what the old values were, and what the new values are
At the serverside level, I am using .NET-3.5 (VB). I know how to send the data bacl. and how to email the data, I just wanted to know how to best format the data at clientside before sending it back. I could have upto 50 sets of id, old, and new values to send back. Sorry for not making that clear earlier.
Example:
How can I modify the script above to generate this?

on my Bookings program i've got a listbox where i can select the booking date of each room, and then i can see the details "UserID, time start time end etc". When the UserID is read from the database it takes the user id number (which its supposed to) but now i want to take that number, and match it to the actual "User Name" and then display the Name.this is what i've got so far;
Dim BookingDetails As New SqlCommand("SELECT UserID,......(and the rest)
then i execute the reader
Dim drBookingDetails As SqlDataReader = BookingDetails.ExecuteReader
and then i'd want to convert the read data, into the actual user name?
When I move or copy files, I'd like to know how to show the actual progress of the data transfer.Something that I don't understand is how when moving or copying files to detect the actual progress of the data transfer. I always put the moving/copying in a background worker and that does fine, but presently I can only report status based on how many (of the total) files have been moved or copied.I've tried to look at the destination and my thinking was to report the progress based on the bytes there, but that doesn't work because it always sees it as being the complete file's size, even though that makes no sense.In fact, if you copy a file using Windows Explorer, it does the same thing, although obviously it's still transferring.

View 4 RepliesI am trying to solve an issue in my application where the following exception is occurring: there is already an open datareader associated with this command which must be closed first. I am using TableAdapters, which maintain their own DataReaders, and everything seems to work fine unless I am interacting with one of my background workers.
In my code, I shadow the Item property of my collections so that I can retrieve the actual data from the database if needed. Here is a sample:
[code]...
Now each reference to the Item get property instantiates its own DataAdapter, so I am confused as to how the same DataReader will ever be used in this scenario. Is there something I am missing? All the TableAdapters do in fact use the same connection object, but I wouldn't think that would be a problem
Can I send an object from client-side javascript to server-side code via ASP.NET ?
View 5 RepliesI know this defeats the purpose of client side vs. server side (refer to title of this thread). What I would love to do is build my own custom progress indicator on the client showing how far a server side code has progressed. I figure if I could only get a JavaScript to fire and render a value of some control at pre-defined intervals while the server is working I could make it happen - but alas I'm beginning to believe that this is impossible. Below is some code that performs three 2 sec loops. At the end of each I want to change the visible value of a control on the browser. [Code]

I currently have a parent Listview and its child Listview displaying in the centre column of an HTML page that consists of three columns left, centre and right. And all looks very good. However I would like to display the child list view in the right column beside the parent list view.
To do this it seems I must somehow generate from the code behind page a new row in the table every time the parent Listview displays a record of its data and then some column HTML so the first child list view will appear in the right hand column.
I'm trying to, from a client-side piece, call off to a server-side piece. I need to do this synchronously. On my server-side code, though, I'm calling off to another piece of code, which I want to have a maximum of, say, 10 seconds to return a value. If I don't have a response within 10 seconds, I want to force my own server piece to set my result equal to 0, and return to the client.
Here's what I have on my server-side code so far:
Public Function GetWebResult(ByVal inputParameter As Object) As WebReturnObject Implements IWebInterface.GetWebResult
Dim result As New WebReturnObject
Dim webItem As WebItem = Nothing
[CODE]...
I realize this code is not functional. The problem is that I'm unsure how I would go about getting back into GetWebResult to set the appropriate return values before it is sent back to the client.
I am struckup with a problem from last two days. I am creating a web application using VB.NET, Ajax & RAD Controls.

I have an application which have multiple tab pages. On of these pages I have a group box with many controls that do something.Now the problem is I want to add exactly the same group box by the current one that can have different paparemeters.This is exactly the way that i want to add comparison capability between to set of parameters.I have more than 500 lines of code that responde to changes of these parameters and does something.Is there any way to replicate the the whole gropbox and use the same code for both and and being able to difrentiate between gropboxes.I think there was an array control in vb 6 but I am not sure if this the best way to do this in vb.net.What is the best way to do this for the least amount of changing the code and wasting time.

View 3 RepliesBasicly I have a program that retrieves data and parses it, which is fine, so it starts from:11:981.8 which equals to November 981.8 now what I have done is split the "November" and the "981.8" into 2 different arrays, with other similar data, now what I need to be able to do, is sort the array in either Ascending or Descending order, however keeping in tact, the November and 981.8 side by side in a list box.
My current code is:
Private Sub sortData(ByVal strYear As String, ByVal strSort As String)
lbDispData.Items.Clear()
Dim strData As String = My.Settings.usage2011
Dim arrRawData() As String

View 2 RepliesI am starting a butterfly program and having an issue and really just barely have it started and would like to get some helpfeedback on how to do this. The following is the instructions and I will make a second post on what code I have so far...The butterfly is going to be moving from side to side in a slightly upward assent when the animation starts. You need to build a set of controls that allow the user to control whether the butterfly ascends (up) or descends (down) and also allows the direction of the butterfly to change (left or right). The best way to implement this feature is through the use of keystrokes that when pressed act to control the direction of the butterfly. Whether you implement this feature through keystrokes or controls, make sure that the feature is communicated to the user.
Butterflies fly by opening and closing their wings. So it is expected that the butterfly will alternate between opened and closed as it wings its way across the form. If the butterfly is moving right, make certain the butterfly graphic displayed shows the butterfly as moving toward the right. If the butterfly is moving to the left, make certain the butterfly graphic displayed shows the butterfly as moving toward the left.
If the butterfly reaches the top of the form in its assent, it should wrap around to the bottom of the form. If the butterfly reaches the bottom of the form in its descent, it should wrap around to the top of the form. If the butterfly reaches the left edge of the form, it should begin flying toward the right side of the form. If the butterfly reaches the right edge of the form, it should begin flying toward the left side of the form. If the user changes the direction of the butterfly, insure that the correct graphics are used in relation to the direction of the butterfly and that the butterfly moves in the indicated direction. Please note that when the butterfly reaches the edge of the form, the butterfly must change direction regardless of any user input.
Ultimately, what I want to accomplish is an AJAX-based messaging system. I already have a database table for messages, and an ASPX to add new messages (and declare old messages no longer relevant).
The current messaging system simply polls the server every 15 seconds, and re-pulls the current message set.
What I am looking to do is: On $(document).ready(), register an ajax callback function that listens for a server-side event (e.g., MessagesUpdated) On table insert/update, fire MessagesUpdated server-side.
This way, whenever the table is updated (or new records added), any clients listening know that new data is available and can re-poll the server then.
Ideally, I'd also like to make the new data available as an event argument (to minimize re-polling the db).
I can find references to something like this in other languages, but I cannot find any actual code examples to get me started.
Assuming this is possible to do via .Net, can anyone help get me started on this?
I'm using the 2.0 Framework. Also while I added a VB.Net tag, I can read C# reasonably well, so please feel free to post in either language.
