• Visual C# typeof keyword for properties, fields, methods

  Why don't Microsoft implement some sort of "typeof" for properties, fields, methods etc For example, lets suppose we have "propertyof" keyword, then we can do the following: PropertyInfo pi = propertyof(MyClass.MyProperty) I will try to explain how this can be used. Lets suppose we have the following method to fetch data from the database: BizEntity[] e = bll.ExecuteQuery("type of the business object", " property name of the business object", ....); It takes as first parameter name of the business logic entity which objects I want to get, and other parameters are names of the properties I want to be loaded of the fetched objects (suppose we have a delay loaded business objects).

• Smart Device Development Mobile 5 SDK for Pocket PC install hangs

  Tried for hours to get Mobile 5 SDK for Pocket PC to install. The original problem was that my McAffe was stopping various scripts from executing. The install hung after McAffe stopped the scripts. Then, after I turned off the McAffe script analyzer, the SDK tried to rollback and attempt another install, but those installs eventually hung. By "hung" I mean the install wasn't using disk or CPU, there was nothing after the word "status" above the "progress indicator", and the "progress indicator" didn't progress. The "remove" option also hangs. Help Not really as it worked for me several times on not so clean systems. Just wanted you to try and save some tim ...Show All

• Windows Forms Maskedtextbox and SelectAll()

  Hi,   If have a problem with the maskedtextbox. I want the select all the text when the the maskedtextbox got focused (via "Enter" event). and then using the maskedTextBox.SelectAll () funtion. It works fine without putting a mask. But when i put the mask = "00000", the SelectAll() funtion doesnt work anymore. Little side question, whats the difference between the mask "00000" and the mask "99999". Can anyone can help me with this thx !

You'll need to post your select after the MaskedTextBox performs its select. You can do thi ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Now that D3D10 hardware is available...

  ... has anyone actually been able to run their own programs using only publicly available resources The October SDK requires Vista RC1, which I'm currently using. Seems that they made some DDI changes in Vista RC2 such that it is no longer compatible and the latest publicly available drivers from Nvidia seem to be for RC2 only (makes sense). Even then, I have no idea if these RC2 drivers actually enable D3D10 on their new GeForce 8800 hardware. I doubt any archived RC1 drivers have the necessary parts (can anyone confirm ) nor would any "in box" default drivers. I presume various developers have been using GeForce 8800 hardware behind closed doors for a while, but they'll have access to Nvidia's developer relations te ...Show All

• Visual Studio Express Editions Database Question

  I have three simple WinForms. One main, which displays a cookbook, organized into title, ingredients, recepie and two buttons, add and edit. When I click the add button, another box pops out into which I want the user to introduce title, ingredients, recepie and then click save. I am not exactly sure how to do this, but I have Peter Wright's books and I am researching. The problem is though, when I want to EDIT a current entry, how do I pull from the database the info which was selected into the second form, edit it, and when clicking save, adding it back to the database I have a related question. I have an application that uses a datagrid to list out what it needs to in the database. The records it lists ...Show All
