• Visual C++ Compile error within code in #ifndef

  This is probably just me missing something obvious, but .... I've got a VS C++ program with a section of code patched out via an #ifndef NAME.... #endif section. The NAME is defined by a /D option on the command line (which appears correctly looking on the Properties page). Within the editor, the correct section of code is grayed out, so the editor at least is handling the #ifndef NAME correctly. However, when the application is built I get a compile error on one of the lines inside the #ifndef section -- it looks like the compiler is either ignoring the #ifndef or somehow the NAME has become un-defined. (I did do a search for NAME within the entire solution, and it is never #undef'd.) Changing it to an #if 0 compiles as expected. Any thou ...Show All

• Software Development for Windows Vista Difference using WorkflowQueuingService and ExternalDataExchangeService

  Hi Im playing with WWF and wondering what the difference is between using WorkflowQueuingService and using ExternalDataExchangeService I have read alot about why we need all these layers when dealing with workflow data exchange (support for pasivation eg). Ok. i thought that ExternalDataExchangeService solved that problem. No I just downloaded chapter 3 of Dharmas book (Essential Worfklow) wich states: " Although various communication technologies (such as WCF or ASMX) can be layered upon WF, they all must use the WorkflowQueuingService to robustly deliver data to passivated WF program instances " Where does that leave ExternalDataExchangeService regarding pasivation And what is the techinal/implemention wise diffrenc ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Custom processor with additinal data - Content pipeline

  I understand one can use the Tag property to add custom data while processing a model. Is that the only way Meaning, do I have to create a whole hierarchy of user defined classes with the Tag property as a root I though of something like deriving ModelContent but that's sealed. Create a collision skin (other than the supplied bounding sphere), add hard points to attach weaponry or any other thing that would require processing of the original geometry or exporting custom data directly from the modeling tool. ...Show All

• .NET Development Logging Data Truncation While Using SQLBulkCopy

  Hi, I am using SQLBulkCopy class of .Net 2.0 to copy data from excel to SQL 2000 database. My problem is that I want to log records whose data was been truncated as the field length in the database was not sufficient enough to hold data present in the excel file. For example suppose there is a column called 'Employee Name' in the database as varchar (30) now if I try to insert data using SQLBulkCopy class from excel file having data of more than 30 characters for some rows then somewhere I want a log which helps me to identify that row number 10 & column number 20's data was truncated due to field length.

• Windows Forms Framework and Windows Installer not present

  I am deploying a project on a large number of user machines. On a W2K machine, when I tested the MSI, it of course, did not have the Framework or the correct version of Windows Installer. But I did get the expected error messages. So I am going to issue install instructions that state the order of install is to first install these two items, and then install the application. Do any of you do anything different Ok, that's a nice feature. Unfortunataly, it doesn't work. I don't know if it works on XP machines. But it does not work at all on W2K machines. ...Show All

• Visual Studio 2008 (Pre-release) Creating WCF clients from Type objects

  I was wondering if there is a way to create a WCF client by passing a Type object of the interface representing the service contract. For example: [ServiceContract] public interface IFoo { [OperationContract] void SomeOperation(); } class Program { static void Main() { IFoo proxy = new ChannelFactory(typeof(IFoo)).CreateChannel(); } } I know that ChannelFactory does not have a method CreateChannel() but I was wondering if there was a way to do the same thing. Thanks, Wells Wells,   You are right, there is no constructor for dynamically creating a ChannelFactory based on the type. I had the same problem for my Workflow Adapter/Connector Pair  solution where the client proxy w ...Show All

• SQL Server Can we get the Next Row Value ?

  In SSRS 2005 we have First,Last and Previous functions which get the related values based on the use. I want to compare with the NEXT row value and print it according to my requirement. My question is How do I get the Next Row Value. Please Help. Could be tricky, however try using a protected variable in the Code view... something like this (untested): protected myprevValue as string public function setString(myString as string) as string myprevValue = myString return "" end function public function getString() as string return myprevValue end function Then you use a hidden text box with the expression =setString(myString) If you have multiple values or want to lookup by row number you can use a d ...Show All
