• .NET Development TCP Sockets checking aliveness

  Hi, I have an app where it is critical that any connection interruption between the server and the client is immediately noticed. Right now I'm using a "ping packet" that I send to the server and the server sends it back. If it's not returned within time x and the server hasn't received a new one within time x the client assumes it's disconnected or the server disconnects the client. However, since I'm sometimes sending large objects over the socket which can take a couple seconds to transmit I can't send a ping packet every 3 seconds or so as it then would time out since the socket might be blocked while sending a larger object.

• Visual C# GetRows Method works in VB but not in C#

  Can someone look at my code below and tell me what I'm doing wrong I converted VBScript to C# for ASP to ASP.NET migration. (I wasn't able to successfully convert legacy ADO to ADO.NET, so sticking with this) I'm getting an error at this line: cartValues = RS.GetRows(-1, null, null); Error Message: Exception Details: System.Runtime.InteropServices.COMException: Application uses a value of the wrong type for the current operation.

• Software Development for Windows Vista WorkflowTrace.log being generated in Beta2

  Hey WWF team, My workflow code is writing trace messages using System.Diagnostics.Trace.WriteLine(), which I view normally in DebugView. As of Beta2, I find that in my bin directory there is being generated a file called "WorkflowTrace.log" that contains 95% of these lines, and it sure ain't my code that is creating that file. Is this expected How can I turn this off Riley Hi Arjun, I wish the final fix will avoid creating file in BIN folder. -- We had a webservice timeout issue recently on .NET 1.1 -- regardless how big we put timeout in the machine.config, it always timeout in 90 sec. ...Show All

  Project converted from VS.NET 2k3 to VS2k5.  Receive the following error in several projects (6/21) that build fine in VS2k3.  The include file exists, is part of the project (auto generated by VS2k3).  Anyone see this   Thanks.

• SQL Server How to read the names of package variables in custom task

  Hi there, I found a lot posts about package variables. But nothing about how getting access to the names of the package variables programatically. Why - Well I want to create a list of variable names from which the user can choose one of in a UI of a custom task. That's all... :) I thought of using the variable dispenser in the Initialize method of the task and then storing the variable names into a property which can be read by the UI through the taskhost. But it seems that you have to know all your variables by name if you want to use then in a task. Any idea Fridtjof In your IDtsTaskUI. Initialize m ...Show All

• Visual Basic CDO AddAttachment sending .DAT file instead of File

  I'm adding the ability for a user to submit an email form, adding a file attachment. So, I've created the upload feature and it works. I've tested the send email functionality and it works also when I hard code the path to the file on the server as Code: ObjSendMail.AddAttachment "E:\vhosts\dev.sheridan.edu\asp\upload_tmp\test.pdf " But, for some reason, when I write the variable in that place, a .DAT file gets emailed to me instead: Code: ObjSendMail.AddAttachment response.write(session ("fileAttach")) I think it has to do with the quotes around the path... when I put the response.write there are no quotes. So, how do I ...Show All

• Visual Studio Team System Workspaces are broken

  I created a team project, created a distributed app in that project and checked it in. I then created another team project, created a native C++ app in that project and checked it in. Doing the above broke Team Build since both projects were associated with a single source control workspace.  So I created a second workspace for the second project, and created a mapping in that workspace between the source control branch and working folder for that project. Team build is now happy, but the project itself is broken.  Opening the source control explorer for the second project shows no mapping for any of the files, nor can I find any ...Show All

• Visual Basic A Pause with a Loop

  Okay...what I want to do seems simple but I've been at it off 'n on for a few days with this & finally decided to post my question. I have a Label I want to flash on & off a few times much like a warning sign. You would think something as easy as: For i as Integer = 0 to 20 Label1.Visible = True Thread.Sleep(500) Label1.Visible = False Next would do it. But it doesn't. I tried throwing a timer in there somewhere but I'm not placing it right. I can get it to run one time (on then off) but that's it. Any suggestions I know this is pretty easy but sometimes easy things can help more then 1 person ...Show All

• Visual Studio Express Editions creating dll's

  hey i am designing a program and i was wondering if it is possible to create a dll in Visual Basic Express Edition well, maybe I should rephrase that. I'm designing a program where when you click a button it opens a text editor(already have that made). Someone told me that to reference the program in the code you need to create a dll(is this true ) Shak, Normally there is a path variable which includes that directory.
