• .NET Development Communication between apps via sockets.

  I am trying to set up a communication channel between two Windows apps. Actually there should be 3 of them. One form is local, another form is located on the same machine, the third form is on a different PC connected via a LAN. My first attempt is to send a few strings of bytes from one form to the other locally. On the server side. This code is working : listenSocket = new Socket ( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp ); int port = Convert.ToInt32 ( "19001" ); IPAddress hostIP = (Dns.Resolve ( IPAddress.Any.ToString ( ) )).AddressList[0]; IPEndPoint ep = new IPEndPoint ( hostIP, port ); listenSocket.Bind ( ep ); int backlog = 2; listenSocket.Listen ( backlog ); StateObjec ...Show All

• Software Development for Windows Vista starting application from setup - not as administrator

  Hello all: When my application is run for the very first time at the end of the installation process, it is running as administrator, because the setup itself was automatically detected and elevated by Vista. Is there any option to run it from setup at usual (medium) privilege level I have tried manifest with requestedExecutionLevel of asInvoker - to no avail. TIA OTNS Here is the answers I have got from MS: your application running with high privilege can not directly create a low privilege application. The best way to do this today is to first create a medium privilege exe that launches your high and low privilege apps. The medium privilege exe can create a low privilege thread and t ...Show All

• .NET Development Get worksheet by name from an excel worksheet

  Howdy, I am working on a project to get data from excel spreadsheets and update an Access database with the new records. The excel spreadsheets are being generated by another department and I have no control over when they are being produced, or how they are being named. I think I have how to access the spreadsheet and extract the data to a DataSet (it seems straightforward). However, to select the data out of the workbook it looks like I need to explicitly name the worksheet that the data is on. Right now there is only ever ONE worksheet in the workbook, but it is NOT named 'Sheet1', the name is automatically generated by the equipment that is outputting the sheets. Here is an excerpt from what I have right now: ' How to get data from ...Show All

• SQL Server Basic Functionality Questions

  We've been trying to implement Reporting Services in our web application. We've run into 2 issues that I'd like to verify: First, HTML rendering. In our application we provide an HTML Editor for formatting . The formatting does not render in the reporting services. I understand that's a known issue with no work around and no timeframe for resolution. Is that correct Second issue comes with tying is the Reporting Services together with our ASP.NET code. Do any of the Reporting Services controls allow you to bind to classes that support the IList Interface Thanks, Frank 1) RS text box control does not render HTML. It supports standard formatting which applies to the entire contents of the text ...Show All

• Visual Studio Express Editions Starter Kit Install Errors

  I am using Visual C# 2005 Express and Visual Web Developer 2005 Express on a Windows XP SP2 system and when trying to install either CSCardGame.vsi or TimeTracker.vsi I get the message: "Installation aborted because the item was a duplicate of an item already installed." I've checked both programs and they do not show up at all in either "New Project" dialogs.  Any documentation on how to manually install these Templates Thanks. Dave Dave - If you rename the CSCardGame.vsi file to CSCardGame.zip, you'll be able to open the CSCardGame.zip.  Inside that .zip file, you'll see another .zip file (CardGameStarterKit.zip).  If you take the CardGameStarterKit.zip file and copy it to your %My Docum ...Show All

• Visual C++ Using Windows API with managed code

  I am trying to read data from a Tape using the Tape Backup functions in Win32 in managed code. The problem is that the only function that I can find thah will read data from tape is ReadFile(), whose 2nd argument is an LPVOID. The buffer that I can use to store the tape data is an array<Byte>^ type, thus I need to convert the managed Handle ^ to an LPVOID. I tried using PInvoke, however the MarshalAs:: has no such type, LPVOID, among its parameters to convert. Does anyone know of a solution to this problem You can use pin_ptr ( http://msdn2.microsoft.com/en-us/library/1dz8byfh(VS.80).aspx ), to create a buffer usable by the unmanaged subsystem. I would think that there are alternative ways to read from tapes, ...Show All

• Windows Forms Write to a specific place in a text file

  Hello everybody I've been programming in C# for a while and done some writing and reading from text files. Now I've come to a point where I want to develop an editor in C#(hehe) and need to know how to insert a string on a specific place in a text file. Lets say that you want to insert a string on a sixth row, six characters from the left side of the screen I hope someone can provide an answer to me. Thx in advance Kind regards Allan H. That's going to make your editor incredibly slow. Each time you insert a character at the top of a 1MB file, you'll have write 1MB-1 bytes to the file. That hourglass is going to get old quickly.
