• Florent SANTIN Reading Bits

  I am pulling an 'int' data type out of SQL Server with a length of '4' which I want to read the bits.  I have no clue on where to start on this as far as declarations or methods to use...I need to be able to read each bits to see whether it is set or not.  Possibly the easiest way I see is to store each byte as an array of bits so then I could just loop through and do my comparisons.  I do not need to write, just read.  Thanks a ton! Dim I As Integer = 10 Dim b As New BitArray ( BitConverter . GetBytes ( I )) For x As Integer = 0 To b . Count - 1 Dim TheBit As Boolean = b ( x ) Next can I just ask - is the data ty ...Show All

• Tryst NotInheritable -> but I want to Inherit :)

  Hi! I'm trying to add a property to System.Windows.Forms.HtmlElement I've created a class that inherits HtmlElement. Howerver, HtmlElement is NotInheritable...so the question is: Is there any way of overriding NotInheritable so that I can make my HtmlElementWithProperty object (having all the features of HtmlElement + my string property ) Any other workarounds that might help Regards, Alex You'll have to fall back on the "aggregation" principle. Create you're own class that contains a HtmlElement and use it. ...Show All

• olgaF How to debug windows paint messages within and across applications

  Hello, I am using Windows XP and VS 2005 with VB.net and I am writing a solution consisting of a set of applications, all running at the same time, with other applications. I have 4 monitors, which means a lot of real estate for applications. I have observed that my applications cause other applications to redraw their screen. This is most frequently when I use the DataGridView control. Scrolling the DataGridView at one point causes a burst of redraws in those applications, and I have to wait until the storm is over. Question: how can I catch and eliminate the messages that are obviously sent from my application to Windows (and thus to the other applictaions). The other problem with paint messages: Within one application, I ...Show All

• HariAdu Merge files

  In the old dos days you could combine 2 files as save to a third file: copy file1 + file2 file3 It still works in a dos shell. I did this: Shell("copy " & file1 & " + " & file2 & " " & file3) I got an error that file3 cannot be found. I know it doesn't exist I want to create it. So I created a bat file: copy %1 + %2 %3 and called it as such: Shell("ccopy " & file1 & " " & file2 & " " & file3) I still get the error that file3 cannot be found. First I don't see how it can tell from the shell that file3 is a file. How do I do this otherwise Do I have to create a blank file before calling it I think to use a .NET code is better than using shell command, because this wouldn't work i ...Show All

• Manoj Verma What To Install From VB Installation CD To Let Users Run My Application And Not Enter VB

  The best way for me to do what I want to do is install on all PCs (using VB installation CD) the minimal requirements to run my application which uses VB 2005, ADO.NET to read/write to an Access database, and Crystal Reports. I ask you what, specifically, should I install on all these PCs from the VB 2005 installation CD After that the next thing I will do is I give each PC user a shortcut file (having a nice icon that says database on it) which runs the exact same executable on a shared drive. My application already has the capability to tell users if someone is already actually using the database via a warning message. The hope is that only one person will use the database at a time. There aren't many users so this sho ...Show All

• Stéphane Beauchemin Finding the applications .exe folder in code

  If I use SourceDir = My.Computer.FileSystem.CurrentDirectory at the start of my application's first Load event I reliably get the folder where the .exe is situated so I can easily locate some other key files there .... unless it has been invoked by the user double-clicking a working data file, when If My .Application.CommandLineArgs.Count > 0 Then (etc.) allows me to investigate the calling situation but then SourceDir = My.Computer.FileSystem.CurrentDirectory only provides the location of the actuated file and not the application. How can I determine the application's folder in code under these circumstances Thanks Nick B Thank you Stephen - sometimes it's so simple! Nick ...Show All

• MeierLink Downgrade Confusion

  The website (http://msdn.microsoft.com/vbasic/previous/downgrade.aspx) used to say "If you require a previous version of Visual Basic, you may purchase Visual Basic .NET and then downgrade to a prior version." We did this, and I still have the printout from earlier this year.   Now the same website says, "If you require a previous version of Visual Basic, you may purchase Visual Studio 2005 Professional and then downgrade to a prior version."   Are we still legal to use the Visual Basic .NET to downgrade, or do we now have to purchase Visual Studio 2005 To downgrade, you have to make a support call, anyway. They are the best people to help you. VS2005 is the latest version of Vis ...Show All
