• SQL Server Inconsistent OLE DB Failure when running SSIS packages

  I have a series of SSIS packages which populate 12 different databases. Which data source & target they use is controlled by values passed down from the SQL Agent Scheduler Job Step using "Set Values" These values are passed to Variables which are used in the Expressions in the connection manager for the database to change the connection string and initial catalog. e.g. REPLACE( @[User::ConString] , "Royalty", @[User::RoyDb] ) These jobs run successfully the majority of the time but each day I get a significant number of failures where one or more target or error trapping table cant be found. They are all using the same connection manager and most of the tables in the database get updated correctly but the ...Show All

• Visual Studio 2008 (Pre-release) Sign a Full Trusted XBAP?

  Can I sign a fully trusted XBAP with a Verisign key so it will work in anyone's browser without security errors Short answer: no. Slightly longer answer: The only way to elevate permissions within an Internet or Intranet deployed XBAP is to use the ClickOnce Trusted Publisher model. This means your end user must agree to installing the cert into their Trusted Publisher cert store. There is no workaround to this. By using a cert from a trusted certification authority, you are merely skipping the step of adding the cert to the Trusted Root CA store in addition to Trusted Publisher store. ...Show All

• SQL Server Convert MS Excel to XML and then insert all data records into MS SQL

  Hi, I am developing a web page for users to input data records. I am seeking the fastest way that users can upload their MS Excel files and the system can help data insertion into one data table. I know XML can insert data records into SQL database easily. Could any one give me some ideas how to perform this issue Thanks a lot. I would like to convert the MS Excel file to XML on the server, rather than training users to export in XML format. Also, users may not all have Excel 2003. Is there a way to convert on a server Thanks ...Show All

• Visual J# vjc error

  Hi; Ok, while building my solution using nant vjc is throwing an exception. I told it to debug in VS 2005 and the error is at malloc.c: void * __cdecl _malloc_base (size_t size) { void *res = NULL; // validate size if (size <= _HEAP_MAXREQ) { for (;;) { // allocate memory block res = _heap_alloc(size); where size = 0. It throws the exception deep under that code but I think the size=0 may be the problem. The call stack is: kernel32.dll!7c812a5b() [Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll] kernel32.dll!7c812a5b() vjsc.dll!6d90d727() vjsc.dll!6d930468() vjsc.dll!6d930480() vjsc.dll!6d8f53a6() ntdll.dll!7c9118f1() ntdll.dll!7c911902() ...Show All

• .NET Development My COM class prevents client app from exiting

  I'm building a plug-in for an application that exports a type interface. I've implemented the type interface using C#/.Net 2.0 and everything works fine. That is until I exit the client app. It cleans up it windows, but hangs around waiting forever, until I kill it from the task manager. I suspect the problem is my COM class isn't implmeneting whatever is called to finalize it. I've tried ~Class, but that didn't change anything. Can anyone tell me what I'm missing, or to an article that describes shutting down a COM server Thanks for the reply Sean. I'll try your suggestion of a memory profiler. I don't believe the COM client (there is only one), is at fault, as others have implemented COM t ...Show All

• SQL Server Using GetDouble() on the PipelineBuffer

  Hi, I'm using the GetDouble() method of the PipelineBuffer to get a double from a flat file, to transform it and to rewrite it to the readwrite input column. The input column I read the double from has a DT_R8 data type. If my input file contains 18.45, then the GetDouble() method returns 18.44999999999, and when I rewrite the double without transformation, the target file contains 18.449999999999 !! The only way to get 18.45 in the target file is to create a RT_DECIMAL output column and to write the result using SetDecimal(index, new decimal(doubleValue)) to that new column (when calling SetDecimal(), doubleValue contains 18.449999999999 but the written decimal is 18.45) If I really want to rewrite the double to my input co ...Show All

• Visual Studio Visual Studio 2005 hangs during launch - won't get past splash screen. Yipes-"help!"

  My Visual Studio 2005 installation cannot get past the "splash screen". Perhaps three weeks ago I had a working Visual Studio 2005 installation. This machine has Visual Studio 2003 also installed, side-by-side, and I needed to do some work with 2003 which was and still is working fine. Last Friday I launched Visual Studio 2005 and it hung at the splash screen. I'm now "dead in the water" with my 2005 work environment and have a work stoppage because of it, which I've been trying to resolve for 3 days. I've tried: - repairing 2005 installation. says it succeeded, but 2005 still hangs - installing 2005 SP 1. says it was successful, but 2005 still hangs - uninstalling the SlickEdit "Gadgets" ...Show All

We own Visual Studio 6, Visual Studio 2003 and Visual Studio 2005. Where is the Source Safe installation on any of these products I must be overlooking it somewhere.
