• .NET Development Error with serialPort class

  I'm having problems with configuring my serial port object. I'm trying to communicate with a PIC18F458 and I have declared my serial port in the program as: serialPort = new System.IO.Ports.SerialPort("COM1", 19230); But when I run the code, I keep getting the error: A first chance exception of type 'System.IO.IOException' occurred in System.dll And when I display the error message, I get this: Error: The parameter is incorrect. Even if I set it to 19200 or other values, I still receive the same error. But if I print out the baud rate, it prints out what value I set. However, it's the only pi ...Show All

• SQL Server exposing proprietary data to SSIS (Newbie alert)

  Hi all, I've exposed my data (that exists in a proprietary format) with the ADO.NET provider interfaces (IDbConnection, IDataReader, IDbDataAdapter and IDbCommand). I can't seem to find any examples of how to get Integrated Services to hookup to this .NET code in my class library. Is it possible My goal is for this provider to be both a destination and a source and for others to be able use IS to manipulate the data however they want. Some links or examples would be great.

• Visual Studio Express Editions Wot to write in order to find the maximum number?

• .NET Development DirectoryInfo and System Volume Info

  I am attempting to retrieve all of the (*.mpeg,*.mpg,*.avi, etc.) movies on a harddrive and return that as an arraylist.

• .NET Development embedding application?

  Hi. I did not know which forum to post this in so I apologise I was wondering in .NET if there is a way to embed an exe application on a webpage (ASP.NET) using .NET 1.1 or 2.0 I have googled about trying to embed applications into html/webpages but nothing came up. Those applications are run inside the web browser as ActiveX components, and thus not ASP.NET applications at all.  So yes, you can do that, but you'll have to create your application as an ActiveX component that can run inside the browser.

• Visual Studio How to hide a SubReport programmatically?

  Hello, We have 4 subreports on one rdlc file. The user can select any number of reports to display. How can we hide or display the selected subreports Since we have all 4 subreports in one rdlc file, the un-selected subreports display "Error: Subreport could not be shown" Please help. Thanks. What you can do is to associate the "Visibility" property of the subreport to a parameter you can set in the report. By assigning true or false for each parameter corresponding to each subreport, you can show or hide each subreport. ...Show All

• Visual Studio Team System Recreating Team Project SharePoint portal for existing Team Project

  Here's the problem: We erroneously installed SharePoint Services with the MSDE database in Beta3 Refresh and have recently upgraded to RTM. Our old Team Project moved over fine but now that we have SharePoint Services installed correctly (i.e. no MSDE database with the SharePoint databases stored in Yukon) our Team Project portal now doesn't exist.

• Visual C++ Lost all visual style on UI controls after importing to VS2005

  Hi, all I had an old project created in VS.net 2002, (native code, c++), it builds/runs fine.

• Visual Basic Random Numbers

     I'm realy green when it comes to programming but I like to think I am learning quickly. However, I cant figure out how to generate a number of random numbers baised on the vailu of a numeric slider. So for example I am generating a number between 1-12 where each point of value for the slider would generate an indiigual number that can all be added to a final total. I would also like to be able to back the slider down to a previous number and have the same total I had last time I was at position x. This is what i have so far: If levelHP = 1 Then hpcalcbarb = ConBonus + 12 LblHpTotal.Text = hpcalcbarb Else ...Show All

• Visual Studio Team System Compare Utility should Ignore White Spaces

  The Compare Utility should have options for ignoring leading and trailing spaces/tabs. Right now if I had someone who checked in something with 4 spaces set for their formatting of their code, and I have mine set to 3 spaces, then the compare will become usless because every single line will be considered different. if it doesn't ignore blank lines, that should also be an option as really, I just want to see what CODE has changed.
