This will help :

HBRUSH CtestMFCDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
  HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
  if(nCtlColor== CTLCOLOR_EDIT )
       hbr=CreateSolidBrush(RGB(0,100,0));
  return hbr;
}

Somethings seem HARD to do, until we know how to do them.

We should use the reflect message =WM_CTLCOLOR on CMyEdit more OOPs Oriented.

If you are doing this in OnCtlColor handler for WM_CTLCOLOR notification, and you want to affect the colours of all of edit boxes, then you can try the last argument of OnCtlColor, which describes the type of control:

HBRUSH CMyDialog::OnCtlColor( CDC * pDC, CWnd * pWnd, UINT nCtlColor)
{
    if(nCtlColor == CTLCOLOR_EDIT)
    {
        // set the colour
        . . .
    }
    else
    {
        // do not set the colour
        return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
    }
}

Hope it helps.

problem with Open of a query to a recordset

Add a class variable that holds the color, and for each edit box, modify that variable.

stop deleting your questions when someone gives you the answer you were looking for.

it's not the first time i say you this, and you still behave like a SELFISH man Mad | :mad:

if you don't want others to see the answer anymore, then don't ask it here ; find a friend and ask him whatever you like. but here (and in a general mean on forums), things are written to be read after a more or less time since it was written Dead | X|

Can we give buffer as input to the ISpRecogniser instead of file. I just want to take the buffer out from a file and give as input to the ISpRecogniser.Is there any function though which we can set the input as buffer.
Plese help me.
Thank you

Guessing you are using ISpStream::BindToFile function to associate the input audio stream with a file, maybe you can try ISpStream::SetBaseStream to associate it with an in-memory stream created with CreateStreamOnHGlobal?

Hi,

I have an application in which I am loading data from a database (in this specific case a large database) into a grid in my GUI. So, I open the query into a recordset using the Open method as follows:

sQuery.Format(_T("SELECT DISTINCT D.fieldA, DC.fieldB
from TableDC DC, TableD D
WHERE D.fieldA = DC.fieldA AND D.No = '3’
ORDER BY DC.fieldB"));

if(!Open(AFX_DB_USE_DEFAULT_TYPE, sQuery, CRecordset::readOnly))
{
...
}

The problem is that the statement that contains the call to the Open method sometimes takes about 2 minutes to execute (and sometimes works ok).
Anyone have any idea of why this happens? And maybe an idea of how I can fix it (speed it up)?

Are the TableD.fieldA and TableD.No fields indexed?

I don't think they are. Not in table D at least.
What exactly do you mean by indexed?

ok - I think I confused indexes and primary keys Smile | :)

do you know how I can see in SQL server if the fields are indexed or not?

And how can I use indexes on these fields to speed the execution of the open method?

Have you considered the Index Tuning Wizard? There's also SHOWPLAN_TEXT and SHOWPLAN_ALL opptions.

As I now, execution of SQL queries can be speeded up by defining appropriate indexes in the database definition. I think you have to add indexes for TableD.fieldA, TableDC.fieldA, TableD.No and TableDC.fieldB. This can be done with the application you are using for database management.

In additions, use the DISTINCT statement only if is realy required.

Use the CREATE INDEX command.

Use the index tuning wizard in the Query Analyzer. This will give you the right index creation scripts optimized for your select statement.

Restore after HIDE?

ROWALI19-Jun-06 2:52

ShowWindow(SW_HIDE) will hide the window and in my case , make the windows of other applications to the foreground and activate them. How can I restore it programatically when my application is not having focus.. Does my application have to be a service..in which case any short cut key will make it active again?

You need a handle or a pointer on your window, and then use ShowWindow(SW_SHOW).

BUT the question is : what is the reason for your window to be showed again ? According to the answer, you'll find the method to bring the window back (e.g. do it from another app -- a hook, or from within your app).

Just an idea...

You could always use RegisterHotKey() and set a hotkey activation. Then in your dialog, you would need to handle the WM_HOTKEY message, and do ShowWindow(SW_SHOW) and make your dialog visible again.

or

You could add a system tray icon, and have the user click the tray icon to show the dialog again.

I would suggest searching codeproject, there are many samples of both.

After you ShowWindow(SW_NORMAL)Use SetWindowPos with HWND_NOTOPMOST for the "insert after" parameter.
