• Visual C++ Socket programming - Problem in function recv() when receive many big packets

  Hi everybody, I have met a problem: function receive() did not return the real value when we receive many big packets in short time. My application contains client side and server side. We use SOCKET object. In server side, we send many big packets (each packet is about 1000 Byte); in client side, we use while() loop to receive the packets that server sends to. the return value [ret]:        char szBuffer[1000];        ret = recv(sckConnect,szBuffer,1000,0); // 1000 is the packet size is sometimes less than 1000 . I have done this test: before sendin ...Show All

• Visual Studio F1 help behavior- VS2003 Vs VS2005

  Hi All, This is for the help system for our VSIP package. If there are multiple keywords pushed as LookupF1 keywords (say keyword1, keyword2, keyword3 added in that order, all added as LookupF1), the dynamic help window in both VS2003 and 2005 displays keyword3, keyword2, keyword1 in this order(ie, last pushed keyword as the first one). Pressing F1 in this scenario- in VS2003 opens up the page for the first keyword, keyword3 in this case (last pushed) and VS2005 opens up the last keyword, keyword1 in this case(first pushed). Is this the expected behavior . How to get the F1 help working the same way for both VS2003 and 2005. ...Show All

• Visual Basic Can't create new Tables, Views or Stored Procs from Server Explorer

  When I right-click on the Table node under Data Connections in Visual Studio 2003's Server Explorer I don't get the New Table node in the pop-up menu (XP SP2 and MSDE). This doesn't appear to be a database permissions issue as I can access the same database and create tables from the same security context using alternative tools (osql, SqlClient.SqlCommand, Enterprise Manager). Nor does it appear to be related to the version of Visual Studio as an installation of the same version of VS.NET on W2k/SQLServer works fine. Is the "New Table" Server Explorer pop-up blocked by XP SP2 or something wierd ...Show All

• SQL Server Outer Join Issues in Sql 2005

  Hi, The following query works fine in Sql 2000 database, but it throws an error ('Query contains an outer-join request that is not permitted.') while executing the query on Sql 2005 database.

But still we are getting the error. select top 2 * from table1 t1, table2 t2 where t2.col8 =* t1.col1 and t2.col9 =* ( select max(t21.col9) from table2 t21 where t21.col8 =* t2.col8 ) We are planning to convert all our sql 2000 databases to sql 2005 databases. We have used this kind of outer join(=* or *=) in many places in our application. It is ...Show All

• Visual Studio Express Editions Adding a data source

  Finally got the Northwnd.mdf file to work.  Now when adding it to an application, the dataset doesn't appear in the "Data Sources" window on the right.  It is listed in the Data Explorer on the left but not on the right.  So,,,, no drag/drop feature on a form.  This is with the latest download, not the beta version.

• Visual Studio 2008 (Pre-release) Variable Where Clause In in Link Select Clause

  How do you create a LINK select statement with a variable where clause The following does not work Dim WhereClause = "Country.Population < 1000000" Dim SmallCountries = Select Country From Country In Countries Where WhereClause Unlike the DataView filters and DataTable.Select(), the "Where" operator in LINQ doesn't take a string. For DLinq, you'll need to construct an expression tree by hand. There should be examples of this in the next CTP. ...Show All

• SQL Server Can This Be Accomplished in My Time Dimension in my AS2005 Cube?

  In my AS2005 cube, I have a time dimension with the following attributes: year, quarter and month. Also, there is currently no hierarchy by design. Is there a way to make a custom attribute/time period that reflects the last 12 months (R12M) and work in the same manner such as year, quarter and month The time dimension would then have: years, quarter, month and R12M. As a result, a user can drop a measure such as Sales Amt and then add the R12M attribute from the time dimension and would then receive the total sales amount for the last 12 months. I hope that made sense. I can and have written a calculated member for R12M Sales, b ...Show All
