• Software Development for Windows Vista SqlDatabaseActivity can't handle output parameters when calling a stored procedure

  Dear all, I have just run into a problem with SqlDatabaseActivity which I downloaded from Microsoft. It doesn't understand output parameters in stored procedures, so it never returns any values for them. It assumes that all parameters are input only. I had previously discovered that it didn't handle @RETURN_VALUE, but fixed it myself. The failure to handle output parameters looks more fundamental, so I am reluctant to embark on trying to fix it. Is there a version of the activity which resolves this issue I do not yet have a blog appropriate for this, but am working on setting one up. Meanwhile, am I missing something Is there a place to upload things to this technical forum I have asked this before, but never go ...Show All

• .NET Development DataTables and SQLDataAdapter events can trigger eachother causing additional hits to the Database

  I've noticed when doing inserts and updates to a SQL database from a DataTable, the SQLDataAdapter will AcceptChangesDuringUpdate and AcceptChangesDuringFill. This is a great feature, except when the data values come from the database such as a Primary key for a new row or default values when no value was specified by the end user, then this causes another RowChanged event to fire and the Update back to the database is called because the RowState is set to Modified when the DataTable Row is updated with the new values from SQL. I'd like to be able to halt notifications on a DataTable under certain circumstances such as while I'm executing an SQLDataAdapter.Fill(dt) or on some other unknown occasion... Is this currently possible or wi ...Show All

• Windows Forms Link from 1 Form to another.

  Hi, i new to Visual Studio, basically I have 2 forms in my project, "Form1 & Form2". I want to know how to link from Form1 to Form2 at runtime. I need it to work as follows, Form1 has a button which when clicked closes Form1 & opens Form2, I tried googling it but cant find what Im looking for, any help would be much appreciated!!! Rgds David I would use a delegate to marshal information you need to and from the forms your using. Its a much cleaner way  to ensure forms can communicate. The example below sends a string from one form to another, but you could send any object and any number of them. public delegate void FormUpdate(String message); Add the following property ...Show All

• Visual C++ Link Step Always Generates Different .exe Checksum. Why? How to disable?

  I'm using Visual Studio 2005. I created a simple helloWorld console application. Each time I link, helloWorld.exe has a different checksum. Only 1-3 bytes typically differ. If I set my clock back, and I can time it so that my link step occurs on the same second as it did last time, then the checksum remains constant. I'm not using any __TIME__ or __DATE__ directives. It's important for my company's revision control system that binaries with no changes in the source code always are the same, so that only "true" changes get checked in. Does anybody know why this is happening, or how to make the binaries not depend on the time of the link step, so they'll be consistent In Visual Studio's help pages, ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. VB 2005 Game Programming: Where to start

  Topic says it all. Were can I get Basic to Intermediate help/tutorials/guide with DirectX and VB. I am looking to make a 2D game but need a starting point. John XNA examples will all be in C#, but there's nothing stopping you from programming with it using VB.NET. I did hear a rumor that if you wanted to make XBox360 games using the XNA framework that you would have to use C#, but that made no sense to me since they are all .NET languages and if the Xbox360 is fine with C#, there's no reason it wouldn't handle games written in VB.NET either. But for the PC, yep, you can definitely use VB.NET to program games using the XNA framework. Thank goodness for .NET. Oh, and for 2D development, definitely check out ...Show All

  How will we be able to access content when apps are running on the XBox using XNA Specifically I can access the System.IO namespace on the Windows platform to load content ( meshes, textures, sounds, etc ).

• Software Development for Windows Vista XA MSDTC

  Hi, I'm writing an app that must support both MySql and SqlServer back-ends. I've created a provider based model for this, and this side of things is fine. However, clearing up unit-tests is a pain, especially when the majority of my business objects do not, and should not, implement delete functionality. As such, I want to run the unit tests using a COM+ 1.5 transaction (thanks for the help article on this btw), each unit test, should it require rollback, will create a transaction, and call ContextUtil.SetAbort() once the test has finished. However, MySql does not rollback the transactions. MySql 5.* supports XA transactions. My knowledge of the underlying workings of this model is slight at best (any links where I can read up fully on th ...Show All

• Software Development for Windows Vista Can someone explain DependencyProperty ?

  Is there some significance to why the SimpleReplicator SDK sample uses a DependencyProperty in the SampleReplicatorChildActivity I'm looking at using replicator, but having difficulty understanding how to access instance state within a composite child activity. For example, if my replicator contains a sequence activity (like the sample), which contains a Policy activity, the only way I can see to get use properties in my policy rules is to access the containing sequence. Is there any way the standard policy activity can just "inherit" the properties of the sequence that contains it I thought maybe thats what dependency properties were for. DependencyProperty allow you to bind to other properties u ...Show All
