• SQL Server DT_GUID to DT_WSTR yields braces around uniqueidentifier

  I'm using a Lookup component to add a DT_GUID column named cat_id to a data flow, which is used in a downstream Derived Column component to add a DT_WSTR column named value. The DC expression simply casts the uniqueidentifier to the desired type: (DT_WSTR, 434)cat_id But when the values are persisted in the destination table's nvarchar(434) column, they have braces around them, e.g. {F475DB7F-5CB0-4EE1-9BF2-758C77D7A6D7} What is introducing those braces, and what do I need to do to prevent it You may remove the braces by using SUBSTRING function in the DC expression: http://msdn2.microsoft.com/en-us/library/ms137541.aspx SUBSTRING((DT_WSTR, 434)cat_id, 1, 40) (if I remember GUID length, maybe the last param should be 3 ...Show All

• Visual Studio Express Editions Install vc++ 6.0 on top of vc++ 2005 express?

  If I install ms vc++ 6.0 pro. ed. (academic price) on top of vc++ 2005 express: will there be a vc++ benefit of functionality or vc++ loss of functionality If I should install and use ms vc++ 6.0 pro. ed. (academic price), should I uninstall anything first, before installing ms vc++ 6.0 pro. ed. (academic price) I did install PSDK and enable MFC with the vc++ express and it works well. Thank you. B. John For one thing the C++ compiler that comes in VC++ 6.0 is old and tired and does not care too much about standards so you should give it a rest. VC++ 2005 is much better in this respect. When it comes to the IDE itself there may be some features in VC++ 6.0 that are missing from VC++ 2005 Express (because you have ...Show All

• Windows Live Developer Forums Contacts Control now available in 9 languages

  We've just rolled out an update to the Windows Live Contacts control, adding language support for German, Dutch, Italian, Spanish, Korean, and Chinese! That's on top of the English, French, and Japanese we hacked together by hand earlier. If my fingers are correct, that's 9 languages covering several of the largest populations of web users worldwide. You can see them in action in the contacts control list view: http://dev.live.com/mashups/trycontactscontrol/ and tile view: http://dev.live.com/mashups/trypresencecontrol/ Select a language from the dropdown list in the middle of the test page and the control will reload with those strings. You can even switch languages after you've signed in! You specify the language or regional m ...Show All

  Does anyone know if it is possible to pass the actual property of a class into a method instead of the value This is what I am trying to do... You have a basic class... public class Car { private int _id; private int _doors; public Car(int id, int doors) { _id = id; _doors = doors; } public int Doors { get { return _id; } } } Then I have a generic method as such... public List<T> GetWhereProperty<T>(PropertyInfo prop) { return a list of T where the prop name given is equal to the value in prop } I would like to call it like such...

• Audio and Video Development Side Scrolling Chapter Menu

  I'm trying to create a side scrolling chapter menu and was wondering if anyone has solved this riddle script side. Basically I want to scroll through chapter images using left and right arrow buttons, so the menu would start like this: < #1 #2 #3 > Then by clicking on the right arrow button it would then look like this: < #4 #5 #6 > And so on. The version I have built simply replaces the images (#1 replaced with #4, #2 replaced with #5 and so on). But I would love to make them scroll so the new images come in as if they are all on the track moving left and right. I did try to solve the problem be creating on long block of all the chapter images, masked behind a div that was only big enough to show th ...Show All

• SQL Server SQL2005 Performance problem with updating subscribers with identities

  Since we've upgraded to 2005 we've had major performance problems with updating subscriber tables that contain identity PK columns set to manual or auto range management. If a table has identity range management set to 'None' (the "old" 2000 way), the peformance is fine. Below are sample tables: CREATE TABLE [dbo].[ID_RANGE_TEST]( [ID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL, [DATA] [int] NULL CONSTRAINT [PK_ID_RANGE_TEST] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] GO CREATE TABLE [dbo].[ID_NONE_TEST]( [ID] [int] IDENTITY(1,1) NOT NULL, [DATA] [int] NULL CONSTRAINT [PK_ID_NONE_TEST] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, IGNORE_DUP_KE ...Show All

• Windows Live Developer Forums map.Find and longitude/latitude problems

  Hi, I have problems using the Virtual Earth Find function. I am trying to first locate a position using the map.Find() method, and then get the longitude and latitude for that position. The problem is that if I call the map.find wih the first parameter as ' ', the onFindResults function does not get called. Further, a map.getCenter() call right after the map.Find call returns the wrong coordinates. A click on the "locate" button, how ever, returns the correct coordinates. How can a output the correct coordinated without the need for the button Or, how can I get the onFindResults function to be called when the map.Find method is finished My problem is show in the example below. The alert box show the wrong coordintes the first t ...Show All

• SQL Server Long wait times for simple SQL on 2005

  I have an existing application deployed on many SQL 2000 servers running without issue. We installed SQL 2005 (8 way DualCore) and the most simple trivial SQL statements are taking an extreme amount of time (e.g. an identical query in 2000 took 10 ms is taking a couple of minutes in 2005). The data in the tables being queried are very small (low row count < 400; and low row size < 1k). When profiling 2005 we see the connection going into a status of 'suspended' with a wait type of 'ASYNC_NETWORK_IO'. There just simply is not enough data being retrieved for a lag to occur returning data to the client. Has anyone seen anything like this Any thoughts I haven't seen anything relating to NETWORK_IO, ...Show All
