• SQL Server Events keep bubbling up, even with Propagate=False

  I've been pulling my hair out for the last couple of weeks trying to make my SSIS package more robust. I'm running SQL 05 SP1 on Windows XP SP2. Right now when there's a failure, the error propagates all the way up and my package stops running. Clearly not very robust. I have a heartbeat portion that makes a connection to the database every couple of minutes. Sometimes it loses the connection in the middle of the night, probably due to some maintenance going on. I have created an event handler to log the error, sleep a couple of minutes and set Propagate=False. This works great. When the connection is down, the error is logged, once the connection comes back, the package just keeps going. I also have an FTP component that receives a file a ...Show All

• Visual Basic listview to richtext drag / drop problem

  I have a vb.net app coded up with drag drop from a listview to a richtext box. Here is the relevant code: using listitem "hp41exec", e.Data.GetData(DataFormats.Text).ToString = "hp41exec", as one would expect. It's difficult to use breakpoints, since it tends to drop text into my source code :( Stepping thru it though, ListViewItemDrag fires twice and ListViewDragDrop fires only once. I suspect what is going on is the richtext object is doing its own DragDrop. Does that make sense If you want to look at the project, I can email it to you. ...Show All

• Visual FoxPro Browsers Insert html in my code

  I'm useing foxpro to create content for my webpages, I insert html code into a memo field. then a web page will grab the data. I like to use ascii characters to keep my code tidy so I can read it when its a web page. My problem is that the browser reads the ascii text and inserts <BR> messing up my javascript. What can I do i.e. Javascript = "function AlertMe() { "; +chr(13)+chr(10)+" Alert(' Alert! ');"; +chr(13)+chr(10)+" } " after browsers: function AlertMe(){<BR> Alert(' Alert! ');<BR> }<BR> RESOLVED! chr(13) will place a <br> in the script. chr(10) is suffecient enough to move the code to the next line and help readability ...Show All

• SQL Server Package fails when I schedule it.

  Two scenarios, 1 worked, 1 didn't: First package I execute SQL (select top 10 * from MyTable) in my SQLServer2005 database. I scheduled it and it ran sucessfully. I changed the execute SQL to run against an external Oracle database. (Select * from SomeOracleTable where rownum <= 10). I preview to make sure the query works and it does return a result set. I execute the package in the Visual Studios IDE and it works. I save with encryptAllWithPassword to the SQL server. I go into the scheduler and select the package from SQL Server (as opposed to the file system). I set the step to execute the package off the server. I enter the security key by clicking on the configuration tab. I assume it saves the password to the package. I cl ...Show All

• Visual Studio Express Editions Use MFC in express

  Hi, Is there a way to acces MFC from Visual Studio Express Where can I get the .h and .lib necessary to link I can't believe they remove the possibility to create MFC applications Express version is not for me but could help our customers to develop third party specific software to interact with our software for free, but actually the plug-in toolkit is MFC based, and does not compile under Express version ... :/ ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. MS - CreateBuffer - Init Limitations

  It seems that D3D10 unnecessarily limits your options for initializing buffers. You can't partially init a buffer, as there is no size for the init data. It must assume that you're filling the entire buffer. Also, placing multiple resources into one buffer is hindered by the fact that there is only a single data source. For example, if I load 5 meshes, odds are I have 5 pointers to data. If I want this in an immutable buffer I either have to make 5 seperate buffers, or string together the buffers first, then pass that off to CreateBuffer. It's trivial to append the data myself before CreateBuffer, but it just seems unnecessarily wasteful to do an alloc and set of copies, just for D3D to copy it yet again. How are other people appr ...Show All

• Windows Forms How to show the caps lock is on balloon warning like Windows

  Does anyone know how I can show that balloon that windows shows when you are trying to logon and your caps lock key is on There are some VB examples out there of how to show balloons, but I need to show one using C# not VB as a warning to users when their caps lock key is on and they are trying to logon to an internal system. Anyone have any links to how to do this in C# or some C# code that will do this I would appreciate it. Thanks, Nathan Ok, I have re-written the vb code into a c# class that will create the balloon tooltip, but I'm having a problem with one piece of it. The class shows and works fine except for when my Timer_Elapsed event occurs. For some reason the Destroy method isn't doi ...Show All

• Visual Studio Express Editions copy dataset

  hey everyone, this is not very new question, sorry about that, but i dont know how to manage to do this. i want to a copy dataset with the tables and stuff, and here's the example code they give: Private Sub CopyDataSet(ByVal myDataSet As DataSet ) ' Create an object variable for the copy. Dim copyDataSet As DataSet copyDataSet = myDataSet.Copy() ' Insert code to work with the copy. End Sub what else should i do with the code to get this work, because that dataset.copy() does'nt add new dataset itself, right the row "insert code to work with the copy" is the problem i guess. what short of code will i need then could'nt find any samples, and dont know how to do it myself. any help for this is appreciated. thanks ...Show All

• .NET Development Domain and static variables

  Hello All I have an application that deals with several AppDomains and I also use static variables. What I have seen is that the static variables are different in each AppDomain. I have found the attributes ContextStaticAttribute and ThreadStaticAttribute but nothing related to the domains. Is this possible to have a static variable holding the same value in all appDomains Thanks, Pierre-Emmanuel Dautreppe Chris Brumme has stated in his blog post http://blogs.msdn.com/cbrumme/archive/2003/04/15/51317.aspx that you cannot pass static data across AppDomains. It might still be possible the the current CLR implementation has some leaks such as the ThreadPool which is shared across AppDomains. It could be possible t ...Show All

• Software Development for Windows Vista Visual Studio 6.0 SP5 setup on Vista Beta 2 (5384)?

  Does anyone know how to get around the MDAC check in the Service Pack 5 setup of Visual Studio 6.0 For some reason it doesn't detect MDAC 2.5 or higher which it requires (even though Vista obviously has a later version - 6.0) and the setup will not continue from that point. I've tried every registry key I could think of to trick it into thinking MDAC is installed. Thanks Ted. Ted, Did you get any more info about this I am running into the same issue. I am digging now but if you got a workaround from another source it would be appriciated. Glen ...Show All

• SQL Server How do you get the last modified date column in SQL Management Studio

  In 2000, the last modified date was show as a column when viewing the various database objects. So, after a long off-line session with a copy of a database, you could sort the query list, by last date modified, and script the recently changed queries to a file. It was very easy to see exactly what was changed recently. How do you do this in 2005 thanks SELECT * FROM sys.all_objects modify_date datetime Date the object was last modified by using an ALTER statement. If the object is a table or a view, modify_date also changes when a clustered index on the table or view is created or modified. ...Show All
