• Windows Forms Control deep inside(mouse activate control on usercontrol)

  Hi to everyone. I have complex gui structure that is I have UserControl(say CoolEdit) that contains another UserControl and 2 buttons. Second UC in its turn contains WebBrowser. The problem is that i need CoolEdit to stay focused wherever user clicks on it and whichever keyboard button pressed. I managed to achieve this only partially. First I override IsInputKey & ProcessDialogKey to prevent container to process navigation keys. Second to prevent buttons( 2 buttons on CoolEdit) to receive focus i used SetStyle (Selectable, false) and also focus CoolEdit when button clicked. But i have problem with second UC that hosts webbrowser - it receives focus when it is clicked. I tried to process WM_MOUSEACTIVATE in webbrowser but it works c ...Show All

• Visual Studio Team System postbuild event

  Hi, Would it be possible to add a postbuild event feature to the database project I have a scenario where I would like to run aspnet_regsql.exe utility to install/merge the ASP.NET 2.0 services database into the database that I am building with VSTS-DB. I basically want to avoid creating the ASP.NET services db schema by hand (or even importing .sql files) -- I'd rather run their tool and point it at the database created by the build. The postbuild event could provide some macros (e.g. Target database name, connection string, etc) that I can then use as command-line switches to aspnet_reqsql.exe. Thanks, Vitaly Just to let you know, we implemented pre and post build events just like you have i ...Show All

• Windows Forms Populating a ListView with Object data, then populating the same object type with the selected ListView Item.

  Hi all, I have an object that has many properties where I need to represent these objects (and their relating information) in a ListView Control, and when I select an Item from the ListView Control I would like to get the propeties of this object. Whats the best way to go about doing this Is it: if I have my AnswerSet object, extract the propeties of the object and assign each one to a SubItem of a ListView Item, and then when this ListView item is selected, create a new object and repopulate it with the data from the ListView sub-items This seems very cumbersome. Is there a smarter way of doing this Thanks in advance. Tryst Store your entire object in the ListViewItem object's Tag property and retrieve it when ever you need. This i ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA - Microsoft lack of vision

  Its real sad that Microsoft, once again, shows this lack of vision for a games development tool: 1: Get visual: Don't force users to write such a lot of code to do just very little. It reminds the Charles Petzold's "Hello Window" hell of code days. 2: Provide visual tools: Let users choose the components, change their properties and write just the required code for the events. 3: Quick development means quick prototype and minimum learning curve. XNA has a lot of things to learn. Definetively it is NOT for students and hobbists. We will have to wait until someone encapsulates XNA framework into a group of visual components, that can be easily drag & dropped, inspected and tested very easily without having to learn lots of n ...Show All
