• Visual C++ Some doubt on WM_PAINT and MemoryDC

    I have some doubt on DC operations in Windows.       1. When we call Invalidate() for any window, does WM_PAINT is sent to all child windows and child of child windows as well       2. I have created a Compatible memory DC for a picture control of a dialog box. I am painting something in the memoryDC and I am using BitBlt() to copy from the MemoryDC to the DC of the pic control in a regular interval. I am seeing when I am calling Invalidate() [both with 'true' and 'false' parameter] for the dialog box, the memory DC is also getting erased, the old painting is lost and a subsequent Bit ...Show All

• Smart Device Development VS2005 Compiler Bug?

  I have some source code that does DES, 3DES encryption decryption based on the algorithm. A lot of bit operations. The same code, with the same testing program, yields inconsistent results: - Compiled under EVC4 for PPC2003 and SP2003, test passed. - Compiled under VS2005 for Win32 desktop platform (UNICODE defined), test passed. - Compiled under VS2005 for any Windows Mobile platform (PPC2003, PPC5.0, SP2003, SP5.0), test failed.

• Visual Studio 2008 (Pre-release) XAML Geometry - How can I do a reverse clip?

  Clip enables me draw only the area within a specified region. I want to draw everything BUT a specified region. Basically, I want to define a transparent ellipse, such that I can see whatever is underneath. Thanks NIK - I don't understand how Opacity would provide an inverted a clip. Here is a simplified version. The XAML below produces a red circle (the area clipped to display) on a white square. NOTE: Instead, I want a transparent circle through the red square, to reveal the white square underneath < Window x:Class = " WinFxGeometry.Window1 " xmlns = " http://schemas.microsoft.com/winf ...Show All

• Windows Forms Eliminating flicker in transparent controls

  Hello all, I am working on an application that requires transparent controls.  I have used Bob Powells method (http://www.bobpowell.net/transcontrols.htm) and it works just fine. However, it is not possible to use double-buffering.  This is mostly not a problem, but for some controls that I use (e.g. a transparent gauge-type thing drawn with GDI+ that changes frequently) there is&n ...Show All

• Windows Forms How to share one WindowsMediaPlayer by two forms?

  I have two forms between which the user can switch. Each has its own music track. One of the two forms is the application's main form. Is there any way that they can share a single axWindowsMediaPlayer control I'm asking this because if I give them each their own WMP control, there is some ugly sound interference even though of course one of the two has been ordered to stop playing. It stops playing OK, but still does 'something' that interferes with the other WMP's sound. Thanks,   Guido That is, unfortunately, not good enough since the form that is instantiated (in my case, form 2) does not ...Show All

• Visual Studio Team System Saving a query after changing sort order results in message

  If you open up an existing query and you click a column heading to re-sort based on that column, after trying to close out the query you receive a message: "Changes you have made in this view have caused the underlying query to be modified. Would you like to save the changes to the query " Yes or No is the only options. I know this is new functionality in Beta 3 Refresh (from Beta 2) but can somebody explain what changed and if this is a valid warning   The biggest problem I have with this is that the only people allowed to create new or modify existing queries in the "Project Queries" are Project Administrators. However, when an avera ...Show All
