• Visual C++ retrieve symbols from the line

  Is it possible to enumerate all symbols from the line using DIA SDK or dbghelp.dll. I know how to get symbol from a function but I need only from the specified line.

• SQL Server SQL Express silent installation.

  I am writing an application that requires SQL Express to be installed alongside. So I try to do the following - Before installing my application, I pop-up a link which leads to "SQLEXPR.exe ADDLOCAL=SQL_Engine INSTANCENAME=MSSQLServer <other parameters> /qb " . But this displays only a basic GUI, which means that the pre-requisite checks for SQL express are not displayed to the user. So if MDAC version 2.8 is not present on the system the installation of SQLexpress fails without any error messages (except in the log files). ( This is not a problem with all pre-requisites :: If .NET is not present on the system, the failure ...Show All

• Visual C# How to dynamically check if a type supports the "+" operator

  All, Has anybody any idea on how we can query a type to check whether it supports the "+" operator Correct me if I'm wrong, it seems to me that we can only query those methods which are named methods, like "Add" instead of "+". Thanks. Noli Operator+ is a named method; if you inspect CIL code that is produced, you'll notice a method called op_Addition. ...Show All

• Visual C++ arrays with changing values

  Hi, While my code(written in c++ and compiled by .NET 2003) is running, some parts of my code causes to change some arrays created by reading from a file with fscanf or created within the code although there are no operations in those parts related with the arrays that are changing. The arrays are well defined and the array names aren't common. Moreover the code runs without giving any errors but at the end, I see that some arrays have changed without my control.(Some new data is probably overwriting my arrays but how and why ) What may have caused such an error How can I fix this Mo ...Show All

• SQL Server SQL Express with Advanced Services - what Reporting Features does it have?

  I work for an ISV, and some of our customers use SQL Server, others use SQL Server Express. I need to develop some reports, so I was happy to read that SQL Express with Advanced Services would have some (limited ) Reporting Services available. Unfortunately, the sign-up period to beta test appears to be over, and so I am left wondering exactly what functions will be available.

• SQL Server full-text search of related tables

  We have a need for full-text search over related tables. I'll refer to these tables as A, B & C. Table A is the base table and is optionally related to table B through an outer join. Table C optionally has keywords that describe table A and are coalesced in a view with table A using a function. We are using SQL Server 2005 and would like to have a single full-text query search over A, B & C. I thought using an indexed view might be the answer, but we have been prevented from creating the clustered index on the view because of table B being an outer join and table C being joined via the function to coalesce its data.
