• Internet Explorer Development some questions about html element

  1. how can i determine if a html element is visible, means doesn't need to scroll to see it (i was trying to use ScrollToView function but it moves the element to the top/bottom of the window although it's already visible) 2. how can i determine if it's displyed on the doc and not hidden, like text under menu (i want to search a text in the page but not in the menus or other hidden elements) any ideas thanks... Amir. found the answer to question 2: instead of using "style" property of IHTMLElement, use the "current style" property of IHTMLElement2, like this: CComQIPtr<IHTMLElement2> elem2 = elem; CComPtr<IHTMLCurrentStyle> style; HRESULT hr = elem2->get_currentStyle(& ...Show All

• Visual Studio Team System Trouble reusing a field name

  I am working on the second version of my project control prototype. I decided to change the format of my reference names. I deleted ALL of my test projects (using tsfdeleteproject) and removed ALL of my profiles. Then I uploaded my new process template. But when I try to create a new team project I get errors that indicate that I can not use the field names because they are being used by my OLD reference names. I can put a prefix on all of my custom fields names (but I really don't want to). Any other suggestions Thanks, Robert ...Show All

• Visual Studio Express Editions how to populate label on different form.

  I'm trying to populate a label on from. The value for this label is coming from another form which opens up the active current form where the label resides, is this even possible and if so can someone explain how to do it using the C# express designer. you need to have a reference/instance of that form in question, and then access the label property either by making the label control public (so its viewable/accessible by the caller class(es)) or create a public property which can get/set the label property. Example of accessing other forms/controls: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=765625&SiteID=1 same thing would apply for a label, except you just change the properties appropriately. so, you want ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Games built on XNA do need XNA framework to run

  Hello all, Not sure if this Question has been asked before and might be a stupid one to some, I was just wondering that Games built using XNA; do they need XNA framework to run on the users machine apart from NET 2.0 framework. PS -> BTW... XNA is really cool and its very easy to make games now.. cheers for the developers .. Regards, Claton I'm sure Microsoft will release a runtime only install just like .Net 2.0 and DirectX as well as a way for you to build it into your games setup program. Based on DirectX I don't expect to see one before RTM. To be honest this makes sense becuase shipping a redist for beta just means people will end up with beta copies who don't know they are getting beta copies when they inst ...Show All

• Visual C++ More _Interlocked intrinsics?

  Are there any plans to support more _Interlocked intrinsics in the next VC++ You took away inline asm in the x64 compiler so it's frustrating not having immediate access to stuff like "lock add/sub" or "lock cmpxchg16b". I think it would be very cool if the compiler supported custom user-writable intrinsics, but getting at least cmpxchg16b would be a great. Brian Kramer wrote: Does the x64 compiler support the __emit intrinsic (I don't have that compiler installed). If so you should be able to create your own intrinsic that wraps __emit. They removed all ability to emit your own instructions for x64. Instead you have to deal with intrinsics like _InterlockedIncrement() which for some ...Show All
