• Windows Forms how to know that a user control is in design mode

  I have a user control which normally displays a large amount of data from an application. This is similar to an excel chart. When I drop this control onto a form, I want to put some dummy data in, so that properties can be previewed. I can't see how (within the control code) to determine that the control is in design mode. How can this be determined Trev Use the DesignMode property on the control (it's actually defined on Component, which Control inherits from). Sometimes that isn't always accurate, so it's sometimes a good idea to use it together with a check against System.ComponentModel.LicenseManager.UsageMode == System.ComponentModel.LicenseUsageMode.Designtime. ...Show All

• Visual Basic Refreshing the News Channel in the VS2005 Start Page

  I have the option for the start page news channel still set to it's default ( http://go.microsoft.com/fwlink/ linkid=45331&clcid=409 ). I noticed that the dates of the articles were way out of date, so I changed the option (Tools | Options | Environment | Startup) for "Download content every" to a different number. Once I clicked OK, the Start page refreshed with the updated article list. I have noticed that this is the same situation on three different machines with VS2005 installed. That is, to get the latest articles, I need to manually adjust the "Download content every:" setting and then click OK. Shouldn't the articles list automatically refresh every time that VS2005 is restarted It seems silly that I ...Show All

• .NET Development Using database relationships in VB.net

  Hi there, I'm trying to create a multi-table relational database with a VB front end, but am trying to avoid using the bound text boxes that VB auto generates when you connect to the data source (a ms access database). Can anyone give me a starting point on how to use relationships with datasets I'm a bit of a noobie when it comes to data storage =[ any help appreciated =] thanks! When you create a dataset in .NET you are able to use Relations collection. So you can add relations you want using Add methods (there are number of). For instance: ds.Relations.Add( "orderToOrderDetails" , orderTable_Id, orderDetailsTable_OrderId) Then when you work with a row and you have to get a list of related rows you can do: ...Show All

    I am working on a application that will need to view contacts from Outlook. The user would like to be able to create and delete contact from the custom application so that they don't have to switch back from app to app. I am not familiar with the Outlook API and I don't know if VSTO is required to do this.   Thanks for your help Hi, Since you're working on an application that only needs to view contacts from Outlook you can simply use Outlook automation to get the contacts.
