• Visual C++ Client in VC8 that uses DLL compiled in VC 7.1

  Hello, We are using VC 7.1 to compile our DLL, and we tried to use it under VC8. Everything works, as we make no use of STL objects in our API, except that our exception hierarchy derives from std::exception. Then, when our DLL throws an exception, the whole program crashes. What are the available solutions to correct this I currently see 2 : Compile the DLL in VC8, but this requires to ship 2 versions, and we have plugins, so we would have to ship 2 versions of each plugin too. Rejected. Make our own base exception class, independent from std::exception, but this requires client code to catch std::exception and our own exception base class. This might be acceptable, but not ideal. Is there any better solution Thank you v ...Show All

• SQL Server Data flow task multiple destinations

  Hi, The further i get with doing my current SSIS package the more i am starting to wonder about best practices and performance. My current package loops through CSV files in a specified location and extracts events from these files. Each file contains multiple events which are a mixture of different types. Depending on the event there are a different number of comma seperated values. In the package i firstly set each event to one column seperated by a comma delimeter. I then create an array for the event which is split by the delimeter. In a script i weed out all elements of the array that are common to all events and set the remaining events to another array. After some processing i come to my conditional split transformation which splits ...Show All

• .NET Development DataView bug in ADO.NET?

  Hi, I have an application in which i think there is a bug with the DataView. It is when i am using Find() method. I add a new row to the DataView and when i use the Find() method with the Rows Id it returns -1. If i add a second row it will find the first row but not the second. This always happens, when using Find() for the last row added to the DataView i get -1 as the result. I have verified that the Id exists in the DataView. I also found some posts on forums that Find() only works if you have ApplyDefaultSort = true or if you are sorting by the primary key field, so i tried this but it is still not working. Has anyone had this error or does anyone know how to fix it Thanks ...Show All

• SQL Server like keyword que

  I have a table say tbl1 id col1 col2 1 hello hi 2 aaa bbb 3 kkk lll I want to write a proc which has a parameter @val and I want to select records from tbl1 based on either col1 or col2 like @val the query describes better than my writing select * from tbl1 where col1 like %@val% or col2 like %@val% but this is killing the performance of the procedure, can I write it in different way How can I improve it Thanks If, on the table, you have an index (other than a clustered index) that can be used to satisfy the query (i.e. a covering index) then SQL Server will choose to scan this index rather than either the table or the clustered index. This may bring p ...Show All

• SQL Server T-SQL Code help

  Hi, When I execute the following procedure, SQL Server creates an error called 'must declare @table variable'. So I did not overcome this error. Would you please help me CREATE PROCEDURE erase @column nvarchar(25), @erasable nvarchar (25), @table nvarchar(25) AS delete from @table where @column=@erasable Hi I don't quite follow what you mean. Basically the code that I posted (and oj) simply builds a dynamic SQL String and then executes this string. If the dynamic string was a SELECT statement then when the string is executed the results would be displayed. If you modify the stored procedure that I gave you and commented out the Exec (@SQLString) part and added: Print @SQLString You would see the string that was created ...Show All

• Visual Studio Express Editions Visual web express database help.

  Hi, I'm doing a team project for a course in college where we have to implement the backend client software for a make believe website. We decided, on suggestion for a few professors, to use visual web express because it has the database features already built in. The problem is that none of my team has ANY background in database. I've learned how to show the contents of a few my tables but I still have not mastered everything. The software needs to be able to add new products and edit current products. How can I make changes to the database through the backend client web page Are there any good tutorials out there Thanks I appreciate the help As you are using Visual Web Developer (VWD) I would ...Show All
