• Visual C++ How to unregister a activex component once it is used by the page moved to new page or using different event

  We implement an Activex component and sign the component, etc. Our application security requirement make us it work like an Applet with respect security and how it is stored and deleted. e.g. If a html page has an applet, it is instantiated in that page and the javascript can use that applet the applet life cycle ended when we move to new page. As I understand it, ActiveX component is downloaded and registered to windows registry with respect to our implementation of DllRegisterServer in the component. We implement DllUnregisterServer() also. But When you move to new page IE does not call unregister this component What am I doing wrong if not how to achieve something like this Can a component call unregister itself explicitly Regards Kr ...Show All

• Visual Studio Team System Must projects be added under binding root of solution?

  If you don't you get: " The project that you are attempting to add to source control may cause other source control users to have difficulty opening this solution or getting newer versions of it. To avoid this problem, add the project from a location below the binding root of the other source controlled projects in the solution." Is there a way to allow a project in the solution to be at a higher level parent than the solution itself The short answer is "yes". The message you see is just a warning and can be ignored in most circumstances (i.e. just click Continue). You can also click the "Don't display this dialog again" to keep from being shown this dialog i ...Show All

• .NET Development Accessing one forms class properties from another

  I have a main form which has created instances of various classes it uses. When a menu option is clicked I want to open another form ,a bit like a dialog window, which enables the user to set various properties in those classes. How do I do this so that this second form has access to the properties of the first forms class instances The properties I want to access are not static. Regards, Gareth by default, all controls are private meaning that its only accessible to the form/owner itself. To make it accessible by public then you need to make that control public (pretty much change private to public) However it's bad practice accessing a control from another form - there should be anothe ...Show All

• Visual Studio Team System Different deploy requirements for differrent environments

  Hi, I have an unanswered thread here: https://forums.microsoft.com/MSDN/ShowPost.aspx PostID=912956&SiteID=1 about how we manage differrent requirements for different environments. Here's an example of a problem I'm having. Our developers are all grouped together in an AD group called SomeDomain\Developers. That group has various permissions assigned in our dev environment. We also have those same permissions setup in our DBPro project. However, we don't want that group to have the same permissions on our other environments. In fact, when we go into our live environment we don't want this group to have any permissions at all. If we use DBPro to do all of our deployments then, unless we change something, that group will ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Your First XNA Game: Load DDS with Alpha Channel

  Hello, just looking at the "Your First XNA Game" tutorial. It mentions using the DirectX Texture Tool to create a .dds file with an alpha channel rather than a .png. Texture2D.FromFile(graphics.GraphicsDevice, "sometexture.dds"); doesn't seem to cut it for the alpha part. I tried putting the following before it: TextureCreationParameters txParams = Texture2D.GetCreationParameters(graphics.GraphicsDevice, "sometexture.dds"); txParams.Format = SurfaceFormat.Rgba32; to force it to use a8r8g8b8 but still nada.

• .NET Development View database data

  Hi, I have an application that is connected to an Access database which already has four records in a table called course. When I run my program, I can add, edit, and/or delete records to the course table at run time. When I close my program and re-run it, I can see the data I added during the last run, no problem there. My problem is, when I'm on the VS 2005 IDE to view the data I added (select the course table on server explorer, click on data > show table data), I can only see the data I added via MS Access and not the data I added at run time via VS 2005. My questions are: How do I know if my application is really saving to the database if I'm not getting any errors Why is it showing only the MS Access data How ...Show All

• Visual Basic Listbox item focus

  I want to be able to determine the index of the listbox item that has the focus in a multiselect listbox. I also need to determine if it was changed from selected to unselected. My goal is to select/unselect the corresponding item in a second listbox without effecting any other items already selected/unselected in that second listbox. Any help with what property to use would be great. In order to identify which item was selected / deselected you will need to maintain a seperate list of the selected indicies and then compare the current list against the saved list when ever you get the selection change event. -Scott ...Show All
