The FPU (x87) uses 80-bit fields for its operations for loading and storing back and forth from the x87 stack. However the Microsoft run-time library sets the default internal precision of the math coprocessor to 64 bits in Windows XP. This can be controlled by the function _controlfp which is documented here:
http://msdn2.microsoft.com/en-us/library/e9b52ceh(VS.80).aspx[^]
There are some documents where Microsoft claims the precision can be changed to the full 80 bits such as this document:
http://support.microsoft.com/kb/q263213/[^]
These documents conflict with some of the statements in this document:
http://msdn2.microsoft.com/en-us/library/y0ybw9fy(VS.80).aspx[^]
Such things are common in the MSDN. I personally believe its a documentation error or perhaps they are not explaining all of the details. I have never tried it nor tested it however. Try it and see.

Hi,everybody. I have a little question: is there MFC Class which allows to obtain R,G,B - value of each pixels in jpeg-file?
|
|
|
|
|
CImage::Load then CImage::GetPixel()
|
|
|
|
|
|
And then use of GetRvalue or G or B.

From secondary threads post messages whenever appropriate to themain thread and let the latter doing the actual GUI updating work.

As I already suggested, from the worker thread, send a message to the main thread whenever you need to play the animation and let the main thread itself to play it.

The code in my above response requires very little changes to the class, it even supports your multiple AVI resource ID and pane ID in the thread class. If you follow the instructions I have provided I am very confident that it will solve your problem. Please try it and see.

Hi All,
I am using VC++ 2003 and Oracle 10. I have created a table in Oracle.
The table has ten fields including a primary key (field).
Is there any function in VC++ to know the extracted field (from database) is primary key?
I am using ODBC..

Can't you just execute SQL command "DESCRIBE tablename"?

How would that work?

I have not used oracle in some years, I just remember there was a command 'DESCRIBE' table
**Update**
Found some old code!
I think he can do this:
SELECT CONSTRAINT_NAME FROM USER_CONSTRAINTS WHERE TABLE_NAME = "table" AND CONSTRAINT_TYPE = 'P';

True, but I couldn't find where it populated anything regarding a primary key.
