• Windows Forms Why is panel width max 32676 pixel???

  I created a Table Layout Panel control including several panels in each cell. Now I detected that the max length for each of these panels is something like 32 676 (panel.width-Value) pixel. How can this be The property should be a Int32-Value! How can I now create a panel which is about 60 000 pixel long (I need this for a diagramm with scroll bar...) Thanks for any help!!! The highest resolution current monitors support is approximately 1600 pixels across. Given that you could use several monitors you'd still need 20 monitors spanned end-to-end to get to 32K pixels of width. I don't see this as an issue. If I were to wager a guess I'd say it is a limit of Windows itself. Michael Tayl ...Show All

• Visual Studio Team System Add Related Work Item to different Project?

  So I'm considering setting my TFS up so that we have a Project for each of several products, and also a project for each of several common assemblies. Normally, a bug would be logged against one of the Products, since the person logging the bug wouldn't (in theory) be aware of the underlying modular structure. Somebody would review the new bugs and decide which module(s) they actually belong to. So I'd like to be able to open a bug and choose Add Related Work Item to make a related bug, but in a *different project*. I get the distinct impression I can't get there from here. Perhaps others have pondered this and have other options. One that I can think of is to have one project for "everything" and use the "Area" to set ...Show All

• Software Development for Windows Vista Type Intialization Error for Custom State Activity

  Hi, We have Created our own custom State Activity called " WorkflowState" by deriving it from System.Workflow.Activities. StateActivity.

But when we come back later and open the Workflows using the Visual Studio Designer, we get the following error.

• SQL Server Manually changing flat file source has no effect

  I have a data flow that reads from a flat file source, goes through one data transformation component to change from unicode to normal text and writes the data to a SQL Server table.  This has been working fine throughout development using a specific source file as input.  I have now manually changed the path and name of the input source file in the connection manager to point to a new file and the task continues to process the old text file. I open the connection manager and check its properties and preview the data and it all looks fine - it is finding the new file.  I also edit the flat file source component and preview the data and it shows the data from the new file.  I run the data flow by right-clicking and se ...Show All

• .NET Development synchronization

  Hello, is there any difference between locking an object to manipulate a resource, and locking the resource directly For example: // class members private object _lock_queue = new object(); private Queue _queue = new Queue(); // access to _queue by locking the _queue directly lock (_queue) { // do something with _queue } // access to _queue via _lock_queue lock (_lock_queue) { // do something with _queue } ... any side effects by choosing one or the other solution It is used by the collection classes that implement the Synchronized() method. While that returns a thread-safe wrapper for the collection object, it isn't thread safe for enumeration. The SyncRoot property allows locking while enumerating the ...Show All

• SQL Server Lookup transformation using effective dates

  Hi, I need to perform a lookup based on a business key and a date in the source that must be between an effective from and effective to date in the reference table. I've been able to achieve this by updating the SQL caching command on the advanced tab but the performance is very slow. I have 6 lookups of this type in the data flow with a source SQL statement that returns approx 1 million rows and this package takes over 90 minutes to run. The caching SQL command now looks like this select * from (select * from [ReferenceTable]) as refTable where [refTable].[Key] = and BETWEEN [refTable].[StartDate] AND [refTable].[EndDate] and I've set up the parameters so that the business key is the first parameter and the source date is the ...Show All
