I have a database creation script. I've run the script after changed the path within the 'FILENAME' option to create the database on an external hard disk and I was able to see and select data from tables as the script run with no errors. However, when I tried to connect to the database from an application and read data from database tables, an exception thrown for SQL Server error 823 "The operating system returned error 21(The device is not ready.) to SQL Server during a read at offset 0x00000000132000 in file 'Database name'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.". I've tried to run database consistency commands against it but they did not carried out and I got an error message. Also when I tried to drop or recover the database, dropping and recovering process failed. Finally, I had to make the database offline then I dropped it. I need to create such database on my external hard disk not on my primary one. Can anyone help?!!!
My English is very pool,pardon me.This is my first time here.Today I come here to introduce a C++ program library which written by myself.This library called Covariant Graphics Library.This library can run on Linux,based on C++14 standard.If you have some questions about me and my library,just tell me.
This program doesn't compile and gives me error "Conficting types of L search" . I ran out of all trials and I am so confused why the heck it gives me this error . I would appreciate your contributions to solve my problem .
the function does front back search of an array, if any number matches it sends back its address.
I try to create my own GroupBox (CButton class with BS_GROUPBOX style) control but that class doesn't get any messages from the mouse: WM_MOUSEMOVE, WM_LBUTTONDOWN, WM_LBUTTONUP and etc.
I can't understand why.
First ask yourself: what constitutes a duplicate value?
Instead of going straight to the keyboard to solve this problem, sit at the table with a deck of cards. Ignoring the suits, lay all (or a portion) of the cards out in front of you. Now working from right to left, work through each card and see if it qualifies as a duplicate per your answer from above. This might look something like:
Compare card 52 to card 51. If they match, remove card 52 from array.
Compare card 51 to card 50. If they match, remove card 51 from array.
Compare card 50 to card 49. If they match, remove card 50 from array.
Compare card 1 to card 0. If they match, remove card 1 from array.
An alternative would be if the card is unique, move it to a separate array. Now you can destroy the original array and be left with an array of just unique items.
There are other ways to skin this cat, but it's really going to boil down to what makes the most sense to you. You might not initially have the most elegant or efficient solution as others on this board could come up with, but those skills come in time.
