Hi all,
I'm making use of an ODBC class written by Carlos Antollini called 'A set of ODBC Classes'. The problem is that in my one function I create an instance of the class and connect to a database. Then I dissconnect. Then later on I start another funtion to perform some transactions of the database, but the I receive an error stating: Exception Message: External exception C0000008. I think it has something to do with the allocation of the environment handle. Because if I remove the first function call it works. But the later on, on a next call it fails again. It fails on this call:
ret = SQLDriverConnect(m_hDbc,
hWnd,
(SQLCHAR*)szConnStr,
SQL_NTS,
(SQLCHAR*)szConnStrOut,
sizeof(szConnStrOut),
&pcbConnStrOut,
(SQLUSMALLINT)drvConn);
Can one assign more than one environment handle when creating more than one instance of the class???
Can anyone please help me.
Many thanks in advance

I created a thread using CreateThread,that I can get the ID of the thread.
I want to terminate the thread now.
I know I can use terminatethread to end it.
But it says that using that way is not a good method.
And I try to use PostThreadMessage(threadID,WM_QUIT,0,0),but the thread would not end!
Someone would like to tell me how to end the thread except using terminatethread?(And I did not use CWinThread).Thanks.
GOOD LUCK

It really a excellent solution of terminating a thread.
But if we do not use MFC,how should do such thing?
|
|
|
|
|
The solution explained there has nothing to do with MFC: you just use a flag that you set from another thread. In your thread loop, check for this flag end stop looping once it is set.

Use the technique described in Newcomer's article: wait for some handles to synchronization objects with a call to ::WaitForMultipleObjects() where one of them (preferably the first one for priority reasons) is signaled when the thread should terminate.
After you have set this event you should wait on the thread handle with ::WaitForSingleObject() to know when the thread has finished completely to be able to clean up the trhead object and other resources you have claimed for the thread.

From which thread you called PostThreadMessage()?

In the main process like a dialog,I create the thread and post the message

Perhaps the worker thread doesn't even have a message pump!

Using the ReadFile() api, how would one determine if the bytes being read are ASCII, MBCS, UNICODE or even UTF8?
|
|
|
|
|
Actually the first few bytes of files is used to identify the type of encoding. For example for plain ascill there will not be any speciall bytes.
For UNICODE - FF FE
For UTF-8 - EF BB BF

It is only for .txt files only. Am I right?
- NS -
|
|
|
|
|
May be. But all other file formats( having text data ) are applications specific such as doc or xls. So its there own implementation.
|
|
|
|
|
This won't work in my situation since I'm not actually reading a file but a pipe. I'm diverting the putput of a console, so the bytes being read could either be ascii or unicode, but I have yet to find an easy way to determine which.

I have a owner-draw dialog,I change its default color to blue.But when the dialog was minimized,there would be a thin rectange left on the screen.
Someone would like to tell me why and how to resolve it?
Thanks.
GOOD LUCK

What do you mean by "owner-draw dialog"?

What I mean is that,the rect of the dialog based window is not the nomal rectange but round rectange or other shape.I also paint its color no longer than gray.
Then,when the dialog is minimized,there would be a thin frame on the screen!
|
|
|
|
|
Are you setting a proper window region for the shape of the window?

Yes,I am sorry.I find the fault of my program now.
When I paint the window,I used GetClientRect() function.
I neglected the fram width!
Thanks very much.
GOOD LUCK.
