• Internet Explorer Development get_Document returns NULL in IE7

  Has anyone seen this behavior In IE7, when get_Document is called on IWEBBrowser2, it returns NULL. Basically, I am doing the following in the OnCreate of the explorer bar (my explorer bar is based on an HTML control): CAxWindow wnd(m_hWnd); HRESULT hr = wnd.CreateControl(IDH_HTML_SPLASH1); CComPtr<IDispatch> pHtmlDispatch; CComPtr<IHTMLDocument2> pHtmlDocument; hr = wnd.QueryControl(IID_IWebBrowser2, (void**)&m_spBrowser); if (m_spBrowser) m_spBrowser->get_Document(&pHtmlDispatch); After the above last line, pHtmlDispatch is NULL. This seems to happen only in IE7. What could be the reason And if pHtmlDispatch is NULL how else can I get hold of the document Thanks Reza, One additiona ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Multithreading and DirectX

  Hello Im working on a DirectX application and have encountered a problem. The application as it is, runs in main thread. All DirectX related things are executed in this main thread. For loading purposes i have two other threads. In windowed mode everything runs ok. All threads wor fine. But in fullscreen mode, it seems that only main thread runs. In first version i started new thrad every time i wanted something loaded and when thred did all work it exited. It worked in window mode but not in fullscreen. I did another test, i have threads running, but i suspend loading thread when it has no work. Then i prepare data and call resume on loading thread. But again inn fullscreen it does not work. From what i observed, it seems that in fu ...Show All

• SQL Server Nested dataregions

  Hi! I'm having some problems with a basic thing I guess. I have a table of visits as the whole Dataset. Let's call it group A. I then group the visits per customer, let's call that group B. After that i filter out some unwanted visits and call that group C. The hiarchy then looks like this, A contains B that contains C. The problem is that I want to know the number of rows in C above the actual table. Something like CustomerName (John Doe) Number of visits (54 from group C but printed out while in group B) Visit 1 blablabal Visit 2 blablabla ... and so on ... As far as I understand the aggregate functions, you can only use them on the current group or a group above, never below. I tried to make an invisible tex ...Show All

• Software Development for Windows Vista Is there a "standard place" to store writeable not plublic shared files to please UAC?

  Our program has two files must be writeable (a database file and a config file) which are shared by all dedicated users of the program on a single system. The automatic redirection to a single users directory path is not helpfull in that case. Before changing our program: Is there a standard place on Vista to store writeable not public shared files (We whant also to pass Vista Logo test...) Thanks in advance I think you misunderstood me. I want a shared folder which is NOT hidden, which CSIDL_COMMON_DOCUMENTS seems to fit the bill. Under Vista the CSIDL_COMMON_APPDATA is hidden and is only writable by an admin so doesn't seem to offer any advantages over using CSIDL_PROGRAM_FILES (i.e c:\program files) unless I'm missi ...Show All

• SQL Server DataGridView: How can I update data in a DataGridView?

  Hi guys, Im having some issues understanding how to manipulate the data that is in my DataGridView The View is created by calling a stored procedure from VB code and works on two tables: people pswds The columns required from Table people are (personid, userid and sort). The columns required from Table pswds are (comment and activeuser). Table people is parent table while pswds is the child table. The Relationship works between both tables using primary keys from both tables: which is called personid in both.

• Visual Studio 2008 (Pre-release) Advice on a plotting application

  Hi I'd like to program a small application (stock prices charting) that can plot several curves on a chart area. Since the data (and its representations) can be used simultaneously in several charts, I was thinking about having a sort of scene (think of it as the actual representation) with the data drawn on it, and then have various widgets (the widgets of the UI) which use the said scene as its content (after appropriate resizing/transforming). In short, I'd have a customized canvas containing the shapes, and then have panels use it as its content. My first question is : when doing so, does the application automatically know about what part is should draw (typically, if a user zooms, a -potentially significant- part of the plot ...Show All

  Hi,     I want to do some smart devices programing . Can anybody knows weather visual studio 2003 .Net support smart device programing Please let me know what are the steps to create project for smart devices programing    Thanks:- Mike I recommend you upgrading to VS 2005 for doing smart devices programming. You can create native applications in C++ and NETCF 1.0, 2.0 applications using C# and VB.NET. VS 2005 supports many different platforms like PPC 2003, SP 2003, WM PPC 5.0, WM SP 5.0. VS 2003 supports building .NET Compact Framework 1.0 smart devices applications i.e. C# and VB.NET and does not support latest platforms like WM.

• Visual Studio 2008 (Pre-release) Custom class inheriting from geometry.

  I'm creating a game and i need a class that looks like this public class Bomb : EllipseGeometry But the Ellipsegeometry is, for some strange reason, sealed so that's not possible I've searched around abit and it seems that i have to inherit from Geometry or Shape instead, but i really cant figure out how to add a visible geometry to any of those objects. Your choice . My gut feeling is that Canvas.Left/Top may be slightly more efficient (fewer object invalidations)-- probably not noticeable, though. In any case, if you set the Stretch property to anything other than None you'll have to animate Canvas.Left/Top, since turning stretching on automatically recenters the geometry. --Anthony ...Show All

• Visual Studio 2008 (Pre-release) How to Use Shared UDT on client and Server
