• Visual C++ Strings

  I have experience in Java and the use of strings, and wondered how to use them (if possible) in Visual c++. Is it something to do with LPSTR Could you point me to an introuductionary article or somethign please Mike C++ and C# are two very different things. You should rather compare C# to Java than to C++, in terms of C++ being compiled into machine code, while Java and C# is bytecode. This means that Java and C# can run the same compiled code on just about any platform, as long as there is a virtual machine (a byte code interpreter, if you will) to execute it within. C# and C++ each have their use, and it's really impossible to judge one over the other in terms of "being better". As for the LPCW ...Show All

• .NET Development Random TCP/IP ports for Web Services in VS 2005... How to control?

  Everytime I create a new Web Service solution in VS 2005, it assign a "random" TCP/IP port when I run the web service in debug mode. Is there any way to control/modify this I tried the ASP.NET configuration, "Start Options", and could not find anything. thx! WRM WRM, Using the "Visual Studio Development Server" will use by default dynamic ports. To change that go to Solution Explorer and then in the Property panes (web project properties) change where it says "Use dynamic ports" to false and then set the "Port Number" to the one you want. If you use IIS, the port is statically defined by the IIS web site. Regards, Rodrigo ...Show All

• Visual Studio Team System Kerberos for Dummies

  Hi All we have a web application which communicates with TFS. This application creates new Work item on the server. We want to create the work item using the credentials of the user logged on to the web application. Therefore we use impersonation in the web app. The solution works fine until the windows profile of the current user exists on the server, but it crashes immediately if there isn't one (HKCU file is absent). I got the following exception: Access to the registry key 'HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\TeamFoundation\Servers' is denied. System.UnauthorizedAccessException: Access to the registry key 'HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\TeamFoundation\Servers' is denied. a ...Show All

• Visual Basic Error while using a datareader

  I can't quite figure out what I'm doing wrong, but I keep getting a "No value given for one or more required paramters". My code has worked so far to use a dr to retrieve specific data from a combobox selection, but when I try to output to a textbox using textbox1.text = dr("columnname") I recieve the error above.

• Visual C# Security and Authentication

  I have a C# .Net console application I wrote that is on server 1. It needs to copy files from server 1 to server 2. The location at server 2 is a shared drive with a domain user as the only user with access. I need assistance with code or tools that will allow my console app to impersonate this domain user so that it can appropriately authenticate to server 2 and copy the files over. I can run it logged into server 1 as the domain user, but I can't schedule it to run as this domain user. Please help. Thanks in advance. There is a very nice sample about impersonating the windows user credentials at the following link. Hope it helps you http://www.codeproject.com/csharp/cpimpersonation1.asp ...Show All

• Visual C++ newbie help: importing functions from a dll in a C++.net project

  Hi, I am using Microsoft Visual Studio 2005. I am trying to create a C++ application (Win32 project/application) that imports functions from a DLL. The DLL, which I did not create, is a Win32 DLL (that uses MFC in a static library). The DLL .h and .cpp files do not contain any classes. Just functions with __declspec (dllexport). I think that my problem is that I am very new to .NET (I am not sure I should post this question in a different form). Here is what I have done: I tried creating a new solution and adding the DLL project to it and then building the project (to generate the .dll file). Then I added a new project to the solution and tried to: 1-Add the dll to this project as a reference: using Project -> References -&g ...Show All
