• Smart Device Development Going wireless advice...

  Hi, I am making a business case for our company to update our inventory barcode scanners and I need some advice. If we're going to use the wireless functionality of the scanners to do merge replication with the SQL server, then will we still need a desktop in the inventory area I figure not, as long as the wireless is working and they can just dock the scanners for charging, but I'm just not 100% sure. It seems quite obvious, but I just want to cover my bases. Thanks. You can write a PDA program that can access directly a remote SQL Server. I have implemented an "on-the-spot" inventory updating program for HP iPAQ2490/2495 through wireless network. My company does not use a bar code scanner. We just ...Show All

• Windows Forms DataGridView AutoFilter whitepaper and sample

  Are you spoiled by the AutoFilter feature in Excel Do you want the same functionality in the DataGridView control Then my new whitepaper and sample are for you. See: http://msdn.microsoft.com/netframework/windowsforms/default.aspx pull=/library/en-us/dnwinforms/html/DtGrdVwAF.asp The DataGridViewAutoFilter library provides a custom DataGridViewColumnHeaderCell with a drop-down filter list that displays each unique value in a column, and updates the filter of the bound data source when a value is selected from the list. A custom DataGridViewColumn is also provided to make using the AutoFilter header cell easier, particularly in the Windows Forms Designer. Customizing DataGridView column header cells is not as easy as customizi ...Show All

  I am to understand that you can use a 360 controller to develope games with XNA. I have plugged my wireless controller in via the play and charge cable, but all it does is turn my xbox on in the next room.

I have posted a link to the documentation sometime in the past couple of days; if you look through a couple of pages of this forum you should find that. It might be in the VC language forum though. Otherwise, it should be possible to find the documentation relatively easily. ...Show All

• .NET Development Hiding inherited members from view...

  Is there a way to downright hide an inherited member without destroying it. Say I derive from a base class and my derived class wants to hide certain members that are public in the base class. How shall I do this Thanks, Devin Devin, exactly what are you trying to accomplish here If you want to "hide" the method from intellisense so it doesn't show up in the autocomplete list in visual studio, you can shadow the method and put a EditorBrowsableAttribute(False) on the method/property. As Luc points out, it is not possible to prevent users from being able to call methods of your base class (for example by casting an instance of your object to the base class) Best regards, Johan Sten ...Show All
