void NewClass::getDow(string symbol, double value1, double value2, double value3) const
// ... do the code to get the Dow values for the supplied symbol.
use the same pattern for the other methods.
Since I do not know what the 3 double variables are, I simply called them value1, value2, value3; I assume that they really mean something; and if they are "returned" values (i.e. variables that you will assign something to them), you better make them either references (prefered) or pointers.
Looks like alignment padding and shouldn't hurt anything, but can be confusing if you're looking at the raw data and not expecting it. If you really wanted to you could change structures to align on a byte.
Unless you are forced to decide yourself the memory layout (for example to be compatible with some other pre-existing code) don't worry about that.
Your arch1 and arch2 are distinct arrays and the compiler place them at the beginning of a 32bit block so that the processor access speed can be optimum.
You can alter this behavior with the #pragma pack directive, setting the packing to 1 byte you'll get what you expected. But -if you're not explicitly required to do that- let the compiler to do its job and decide by itself how to place variables.
I need to change the playback rate of a video file. The IMediaSeeking interface has a SetRate method which is supposed to do this - but I get an E_INVALIDARG when I pass the new rate. I have FiltrGraph manager which has a Source filter (using the AddSourceFilter method), a GrabberFilter and a NULL Renderer. (Changing the Null Renderer to a default renderer did not change the result - I am still not able to show the video in slow motion or fast forward (speeded up). If SetRate is the correct way to do it, is there sample code I can look at? (Will be happy to post my code here if needed). If there is another way to do this, I am open to all suggestions.
Greetings - my first question so please forgive any faux-pas I make..
My Win32 application loads a number of embedded Web browsers, each of which load and play a Flash movie.
I want to find a way to control the volume of each loaded Flash movie independently of each other. My target platform is Windows XP so I can't use the mixer APIs that I hear are available on Vista and 7.
Here is the code with error checking etc. removed (I'm using a very simple Flash API call to test)
I did and I get the same access violation error. Even if it worked though, wouldn't that just let me control an instance of Flash that I load versus an instance loaded by the browser (which is what I want)?
I think each browser instance must load it's own version of the plugin or controlling Flash parameters in one would control them all.
