The docs for ICLRRuntimeHost::SetHostControl claim that it can return E_CLR_ALREADY_STARTED. I have been unable to find a definition for this value. Ideally, I'd like to know what the appropriate header to include is (it does not appear to be in corerror.h) but if someone can provide me with the canonical value too I can live with that.
Thanks
I can't seem to find it either and I'm usually pretty good at finding missing or misspelled constants. You could try calling the method after initializing the CLR and if it does in fact return the HRESULT that it's documented to return, you could just trace it. But it definitely seems like a documentation bug.

I couldn't find any proper explanation of what NSPasteboard.WritingOptions does.
what does this method do?
what is .promised?
I need to use a few of the VideoCapture::set() options for openCV. They are here;
http://docs.opencv.org/modules/highgui/doc/reading_and_writing_images_and_video.html#videocapture-set
But I cannot find anywhere something that specifies the range of values that can be used to give each parameter a value.
Can someone help?
That information is really missing, and with some of them you really need to take a hit & miss approach.
For the time being, you can check the return of VideoCapture::set() to see if the method succeeded in setting that parameter.
I have a table called settings, when I would change or enter data into the form it did not change the data in the table. In addition on form an image upload file is not running, There may be the wrong code below.

Maybe someone can help me Related to this.
What you are doing here is tottaly in secure and your data can be hacked / manipulate really fast.
Why dont you use a framework like codeignighter there are about 100 easy frameworks that will help you manage database a lot easyer.
Are you sure that you are updating the wrond ID? where id = 1, seems to be not dynamic.
Please post your error http://www.w3schools.com/php/func_mysql_error.asp
I know it is not so related to your question, but you should see these light frameworks:
http://kohanaframework.org/
https://github.com/ElbertF/Swiftlet
http://ellislab.com/codeigniter
You're not checking the return status of of your query, so if it's not working you wouldn't know. Do this:
mysql_query("UPDATE settings SET site='$name',keywords='$keys',descrp='$desc',email='$email',fbpage='$fbpage',twitter='$twitter',gplus='$gplus',disclaimer='$disclaimer',template='$template' WHERE id=1")
or die(mysql_error());
Note: mysql_*() is deprecated: you shouldn't use it. Use mysqli_*() or PDO instead.
Also: You are susceptible to an SQL Injection attack. You should escape your input variables with mysql_real_escape_string() (or the equivalent if you switch to mysqli), or consider moving to prepared statements.
Is the parameter spelled "adress" or "address"?
Here's the API doc: http://developer.eventbrite.com/doc/venues/venue_new/
Where it says:
address The venue adress (line 1).
I ask this question because I'm porting some code, and it looks like we have been using "adress" and from looking at various github repos, it looks like this is considered one of the "inconsistant" variable naming issues related to this API.
I know the misspelled parameter is working.
I want to use the API correctly if I can, and would like to use "address" and just want confirmation that the it will indeed work, and that "adress" only works to be backwards compatible.
Thanks in advance!
Great question!
I fixed the 'adress' spelling typo, but the older spelling of this input label is still allowed (in order to ensure backwords compatibility with existing apps).
We don't have any plans to drop support for the older, misspelled attribute name - but, if you are revisiting old code, it won't hurt to fix the typo on your end as well.
The change should help ensure that the venue object's schema / attribute names remain consistent on input and output.
I keep getting "NullReferenceError" in my output, could someone kindly explain what exactly this statement means.
Somewhere in your code, you are trying to access a member of a reference type, but the variable actually is null. Without code and a stacktrace it's impossible to say what exactly happens. It might be because some parameter is expecting a value but isn't supplied one.
If it helps, a decent description of NullReferenceException -- why/when they occur, and how to prevent them -- at http://www.dotnetperls.com/nullreferenceexception
