• Visual Studio 2008 (Pre-release) .NET WebService Studio and WCF

  Has anybody managed to get the .NET WebService Studio to generate a proxy assembly so that a WCF service could be tested All I get when I connect to an SVC endpoint (our WCF is hosted in IIS) is that the WSDL is successfully consumed, but the Proxy node looks like: //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:2.0.50727.42 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ // // Assembly WebServiceStudio Version = 2.0.50727.42 // As a result, the I ...Show All

• Visual Basic Streamwriter in VB 2005

  This SHOULD be easy. I must be missing something. I'm assembling a long string and trying to write it out to a file. If I display it in a message box or textbox, it looks fine. But when I write it out to a file, it gets chopped off. I thought it might be my data, because it is supposed to be HTML, but it seems to be related to the amount of data, because it chops off at about the same number of lines no matter what the data. I tried breaking it into smaller strings and doing two writelines, but it still does the same thing. lname = names(1) outFile = "D:\Class of 57\updatehtm\" & lname & ".htm" output = New FileStream(outFile, FileMode.OpenOrCreate, FileAccess.Write) fileWriter = New StreamWriter(outp ...Show All

• Visual C# Constructor Logic???

  In dealing with Forms in .Net and they have a form load function that does some things when the form is loaded, I was trying to figure out would i be able to do the same thing if i added the logic in the forms constructor... Like say if i wanted to show some data values when the form loaded, would i be able to add this logic to the forms constructor instead of adding it to the form.load() Ahmedilyas is very right on this one. java.net recently published an article about the five habits of highly profitable software developers which very much applies to everyone. They talk about this issue specifically: " Habit 1: Constructor Performs Minimal Work - The first habit is for an object's constructor to do as little work as pos ...Show All

• .NET Development RFID Reader Project

  Hello, I'm currently working on a project which involves a serial port RFID Reader. I have connected the Reader to COM2 of my PC and i'm trying to get the signals from the RFID Tags. I'm using Visual C# and SerialPort class. The problem is that i can't read or write to the port. I even tried to write something to the port using port.Writeline("string") and then read it with Readline() but it seems that nothing is written and nothing can be read. When i set the RtsEnable to TRUE the BytesToRead property changed from 0 to 9 no matter what i did and still i couldn't read anything. I also wanted to ask you if you have any code samples to send me or if any of you has written a similar program that works. I need to fix t ...Show All
