I've been using VS 2005 for quite some time and will be jumping to VS 2010 shortly. Are there any gotchas to be concerned about in making that transition? Is this a side by side install?

From what I've read in the documentation, both of these methods roll the state of the datarow back to where it was the last time AcceptChanges was called. So what is the difference between them? Am I wrong about that?

View 2 RepliesThe particular control I'm trying to figure out is a UserControl. When I design it as a separate DLL, add it to the Toolbox, then drag it onto the form, it shows up. But when I declare the instance in Form_Load & add it to the Forms Controls, it doesn't show up. (Note that I'm dealing with two different UserControls here as what I don't really want to do is create it as a DLL. It's specific to this project & that's where I want it-in this project. I suppose I could create it as a separate project in this solution, but again-that's not what I want to do. I can add a UserControl to this project, but I can't seem to *use* it. Frustrating.)
Dim X As New Class3
X.Size = New System.Drawing.Size(96, 74)
X.Location = New System.Drawing.Point(5, 5)
Me.Controls.Add(X)
Me.Refresh()
Class3 inherits System.Windows.forms.UserControl, and contains a label.OK, found that I can make the UserControl appear by setting the BackColor (X.BackColor=). Doesn't seem like I should need to do that as it's set in Class3, but apparently when I add it to the form it picks up the form's backcolor-which might be the way UserControls work.
But, it still doesn't show the label that's on the UserControl-just a block of color where I placed the UserControl.And now, I might have solved this problem only to raise another. I finally noticed that although Class3 had an InitializeComponent sub it lacked a Sub New-so it never called the InitializeComponent sub.
I added a Sub New that does nothing except call InitializeComponent & now I'm getting the whole thing. I guess now the question is why the Sub New is required for Class3 but not for the DLL? (Or maybe it was created automatically for the DLL but not for Class3? I'll check the hidden code in the DLL project to see if it was created or not.)
If you have a form with two datagridviews that were dragged on to the form from a datasource that have a parent/child relationship with foreign key constraints. Is there any difference between using the binding navigator Delete button or adding a button to the form and in the Click event put "somebindingsource. RemoveCurrent". Basically what I'm trying to find out is if clicking the navigator Delete button causes "Removecurrent" or does it do something else or something additional.
View 2 RepliesIs there any difference between VB 2005 (from Visual Studio 2005) and VB.Net 2.0, either for using ASP.NET or Windows-based apps as a front end for SQL Server databases? I'm upgrading from VB6 to Visual Studio 2005. My research seems to show that VB.Net 2.0 is integrated into Visual Studio 2005, and the VB-specific books seem to only refer to VB in terms of 2005, 2008, etc.; I'm just trying to find out if they are the same or what the differences are.

View 6 RepliesI am trying to use a free 3rd-party DLL (SmartWIM.DLL - Smartdeploy Imaging Component) which is, essentially, a COM wrapper for the WIMGAPI DLL for creating images of Windows drives.You have to register the dll with REgSVr32 of course Now, included with the installation package is a VBS that does a CreateObject for the SmartWIM object. When I use the VBS I can successfully create an image with the CaptureImage method.However, when I convert the same code to VB.NET and called exactly the same method, the CaptureImage method "hangs".By that I mean it successfully creates an image file but then doesn't do anything else. I am at loss to understand why it would work when run via a VBS and not work in a VB.NET Console application?

View 12 RepliesI am trying to calculate the difference between 2 times.
So far I have 4 labels.
Label1 = Current date and time.
Label2 = Contains the exact time that the application was last closed.
Label3 = Contains the exact time that the application was opened.
Label4 = I want this label to say how much time in seconds had elapsed between the application last being closed and the application being opened again, in other words the difference in seconds between label 2 and label 3.
Below is what I have done so far, but despite repeated efforts I can't seem to find a way of getting the time difference to show in label 4?

I am looking to create an application that uses a remote mysql database, takes a picture from a live video stream, and also interfaces with an RS232 weighing scale. I'm just looking for a one or two sentence definition on what the huge differences are between VB Express and Standard.
I am a PHP developer and I have never worked with VB before (well maybe since high school 10 years ago). I am looking to either use vb or c++ to create this, but I have limited knowledge of any programming outside of web programming.
I have a DataTable with two DateTime columns: "start_time" and "end_time".Now, I want to add a third column that calculates the difference between the two DateTimes. But I can't seem to figure out how. I've tried to set the .Expression-value to "start_time - end_time", but it says that "-"-operator is not allowed on DateTime.

View 3 RepliesI'm recreating a program (don't ask - it is embarrassing) in Visual Studio 2005 VB where I read a spreadsheet in an then select values from certian rows. I added the Interop reference and the MS Excel 14 object library, but when I type something like:
Public oSheet as Worksheet
...
x=oSheet.Cells(Row,1).Value.ToString
I'm concerned because when I type the period after the ) it does not allow me to select value. I type it in and it does not give an immediate syntax error but I'm guessing that when I try to run this, it will fail the build. Is there an other reference I need to add or do you get the value of a field differently for Office 2010 than we did for Office 2007?
