• Windows Forms Overriding an 'invisible' property

  UserControl has a property called Text which is hidden from the user at design time. How do I override Text such that the user can 'see' it If I may ask a related question... How do you control the initial value of the Text property once it is made visible By default, it is set to the name of the control. I would like it to be initially set to nothing, such as what happens with the TextBox. I appreciate your help. ...Show All

• Visual Studio Team System Failed to merge the code coverage result of dll

• Visual Studio 2008 (Pre-release) sample source to return stream from service to client

  I've got a service returning IEnumeration<Customers>, and sometimes this set can get larger than the buffer size of 64k. Now, instead of raising the buffer size I'd like to return the data as a stream, but am somehow blind how to achieve this using serialization. My service right now is something like this: IEnumerable < Customers > GetSomeCustomers() { return SomeCustomers(); } My client does call this using a proxy: IEnumerable < Customers > somecust = myProxy.GetSomeCustomers(); Now my Service would need to serialize the data referring to the DataContract of Customers, and return a stream, but I don't know how to serialize and deserialize the return value of my s ...Show All

• .NET Development Unsubscribing to events from COM Client doesn't work

  I've created a .Net component that has a COM interface. This interface contains events. I've also got a VB6 client that connects to this component. It recieves the events using the VB6 WithEvents "mechanism". Setting the WithEvents variable in VB6 to nothing doesn't make the events stop fireing. Looking deeper into the problem I see that the IConnectionPoint->UnAdvise call that the VB6 client makes when setting the WithEvents variable to nothing fails with error code 0x80040200. The problem gets worse if I set the WithEvents variable to a different object, since the first object still fires events, even if I have no reference to it anymore. I get the same result using VB.Net as C# to create the component. Is thi ...Show All

• Visual Basic Opening a form when another form is loaded

  Hello, On the form1_load event, I have a line of code - "form2.Show". This works fine, except it shows behind the original form. Is there a way to make sure it's at the front Strangely, if I apply the code to a button, it does appear in front. But if it's on load, it goes behind. Thanks :) Hello, Thank you all for the help. I did show the form modally, but also didn't realise this would stop form2's code running whilst open. I'm now using Dave299's method - again, thanks Dave and everybody who helped - great community :) ...Show All

• Windows Forms How do I set a ComboBox to ReadOnly?

  Hi there, I am using a form for a Client Add/Amend/Enquiry, and require a ComboBox to set certain Client details. The available items for selection are defined at design time in the Items collection property. Add/Amend works just fine. When I use the Form for the Enquiry, I set the Text property of the ComboBox to the value retrieved from the database. I want to make the ComboBox ReadOnly, but no ReadOnly property is available for this control. Setting the Enabled property to false leaves it looking very dull grey and insonsistent with the rest of the Form. The only option I can think of is to replace the ComboBox control with a TextBox control for the enquiry, which isn't great. How else can I get around this Thanks, JackSt ...Show All

• SQL Server Optimizing tables

  Hi, We have 3 tables in sql server for simillar information about 3 different countries. some times I select from all countries so I need to use all tables and some times just one country so I select from one table. I want to know that is it good to combine these three tables into one and add one field to define the country name Which way is better, my own way or this new one Please let me know the advantages and disadvantages of each of these ways.
