I think you'd better call Ghost Busters.

Sorry, I couldn't resist.

Honestly though, I have no idea what you are talking about.

Windows XP: If a top-level window stops responding to messages for more than several seconds, the system considers the window to be hung and replaces it with a ghost window that has the same Z order, location, size, and visual attributes. This allows the user to move it, resize it, or even close the application. However, these are the only actions available because the application is actually hung. When in the debugger mode, the system does not generate a ghost window.

Quick regular expression question pls

jkgh24-Jun-02 4:02

How do I write a regular expression for ISO8601 date and time with timezone? More specifically, how do I detect the presence of the timezone bit using regular expressions.

I'm allowing a very limited set of the possible formats for ISO8601 to make it easier.
eg.s "2002-03-22T14:26:39Z", "2002-03-22T14:26:39+01:00", "2002-03-22T14:26:39-01:00"

I get stuck when looking for the '-' sign and I don't seem to be using the escape sequence properly. I'm working from our own http://www.codeproject.com/cpp/rexsearch.asp, but clearly don't understand them properly.

Thanks in advance.

Html control

I'm using CHtmlView - derived class CHtmlCtrl (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnmsj00/html/cpp0100.asp) for use in dialog boxes. I need to navigate that control to some page (for example about:blank) in dialog's OnInitDialog(). But Navigate() is not blocking function, how to block until CHtmlView::OnDocumentComplete() is signaled ?

Read-only CRichEditView

24-Jun-02 2:03

I have set the rich-edit control of a CRichEditView to read only
(GetRichEditCtrl().SetOptions(ECOOP_SET, ECO_READONLY); )
which works fine, except that the scrollbar is then also "readonly" - the user is unable to scroll the text in the window! Is there a solution? (Yes, I've tried EnableScrollBar.) TIA.

Here is my solution :

1. open both databases, select * into source recordset, create recoprdset in destination database
2. select all rows from source database into source recordset
3. destination recordset.AddNew()
4. copy all field values from source recordset to destination recordset
5. update destination recordset
6. go to 2 Smile | :)

Re: Copying data from one database to another

It means that i must use CRecordset or i can use and CDaoRecordset?

It depends what database acces are you using.
CDaoRecordset is dor DAO, CRecordset is for ODBC.
It is recommended to use ADO or ODBC, i'm using this wrapper class for ADO : http://www.codeproject.com/database/caaadoclass1.asp
CADODatabase + CADORecordset

my function for easy copying of recordsets is here :

void CSynchronizeDlg::CopyRecordset(CADORecordset &dst, CADORecordset &src)
{
	CString tmp;

	for (int i=0; i<src.GetFieldCount(); i++)
	{
		if (src.IsFieldNull(i))
		{
			tmp.Empty();
			dst.SetFieldValue(i,tmp);
		}
		else
		{
			src.GetFieldValue(i,tmp);
			dst.SetFieldValue(i,tmp);
		}
	}
}

CWinApp::Run()

Does CWinApp::Run() gets called automaticaly when starting the app, or do you have to do this yourself?

I've deprectated the Run-function, just added a messagebox in there and a call to the parent-Run. But the messagebox never appears, so I guess Run() isn't called automaticaly. (or am I wrong?)

And how do I have to call Run()? Just calling Run(), or is there a Start() function like in java? And from where? From Initinstance()?

Default ID for the "Enter" button

23-Jun-02 23:31

Hi
How can you change the default IDOK for the "Enter" button on your keyboard. My problem is that the program exits when i hit "Enter"...I am not looking for a "Accelerator solution" because then you cannot use "Enter" for the buttons in my app if a button is selected.
By the way its for a dialog based app.

Tnx in advance

Frank
