• .NET Development DataSource and DataSourceView

  The Beta2 sqlDataSource and sqlDataSourceView are great.  But it would be real nice to get the data type of the column, like the DataColumn collection in the DataSet. Does anyone know if this functionality is likely to be added OK I have it figured it out, but it is not easy.  I guess I could make my own control......... Dim args As New System.Web.UI.DataSourceSelectArguments("SomeSortExpression") Dim d As System.Web.UI.WebControls.SqlDataSource Dim v As System.Data.DataView = d.Select(args) Dim c As System.Data.DataColumnCollection = v.Table.Columns ...Show All

• .NET Development Dataset serialization

  I have an issue with the Dataset serialization. I have a class, say BaseDataSet which inherits from the Dataset. More classes inherit from BaseDataSet. I would like to pass on the object inherited from the BaseDataSet back to the client via a web service. Before passing on I cast the derived object to BaseDataSet type. On the client, I am not able to down cast the dataset back to the specific class which is the type of dataset passed across. Are you applying the serializable attribute to all your descendents [ Serializable ] public class BaseDataSet : System.Data. DataSet { } [ ...Show All

• .NET Development XML Nested relations using Dataset WriteXMLSchema

  Hi, I'm trying to generate an XML schema using the dataset method WriteXmlSchema. The dataset contains four tables and several relations as shown below. The CompanyDataTable is a parent table which has two child tables: CompanyAddressTable and CategoryDataTable. Whereas the relationship with the first child table is one-to-one, the relationship with the second table is one-to-many (a single category can be linke to multiple companies). Setting the nested property to true for the first relationship generates the XML schema with no problem, but enabling the nested property of the second relation pops up the following error: "A child ...Show All

• Windows Forms Event firing in DataGridView DataGridViewComboBoxCells

  I have a DataViewGrid (virtual) to which I have added a row of DataGridViewComboBoxCells. My problem is that when one of the DataGridViewComboBoxCells is dropped downand you click on any of the other DataGridViewComboBoxCells in the same row then no event appears to fire. The drop down closes but the edit does not move to the combobox you clicked on. This problem only occurs if the first combobox is dropped down and you try to navigate with a mouse click. If the current box is not dropped down then the click navigates to the correct box. Navigating with the tab works whether the first box is dropped down or not. Can someone tell me what e ...Show All

• Visual C++ Class inheritance in Visual C++ .NET

  I was reading the following article in the December 2004 issue of MSDN Magazine, http://msdn.microsoft.com/msdnmag/issues/04/12/CustomFormsDesigner/default.aspx entitled, "Tailor Your Application by Building a Custom Forms Designer with .NET." It's pretty interesting stuff, and the code download is written in C#. There are several classes that inherit from numerous interfaces. I have the 2003 version of Visual Studio C++ .NET standard, in which when writing a class declaration, you can only inherit from one class or interface. I'm wondering if there is a way around this problem, as I would like to create a similar Windows Forms Designer in C ...Show All

• Smart Device Development Thread Issues

  Hi, I’m working on a migration from a simple windows app to a PDA app with Threads. After to inspect a lot of code, i found that i have a problem with the inicialitation of a thread (the app just die with the "System.NotSupportedException was unhandled Message: An unhandled exception of type 'System.NotSupportedException' occurred in Unknown Module."). I identify the thread making sleep all the others threads form the app after invocation of start(). In that moment, when the scheduler gives execution time to the thread, the app dies.

• Software Development for Windows Vista BizTalk 2004 Migration to WFF

  If I start with BizTalk 2004 today, is there a migration strategy for converting the workflows to WWF Hi, this is just my 2€cent thought: As I understand it , Biztalk will be build upon WWF one version after the comming 2006 version. I suppose a migration path from BTS 2004 to BTS 2006 will be available. I don't think there will be a migration from BTS 2004 to WWF : they are unrelated technologies. I would probably go for Biztalk 2004 if I need all the features of BTS like reliable messaging , adapters, scaling out/in, survival of process restart  etc...  Again just my 2cents. ...Show All
