COleControlSite and COleControlContainer provide an implementation of the OLE interfaces for ActiveX control containers (IOleClientSite, IOleInPlaceSite, IOleControlSite...)
I haven't used MFC for awhile. You might want to try using CWnd::AttachControlSite on the new view. It's protected so you'll have to derive and hack (you'll probably be seeing the ASSERT dialog in your sleep). This is the kind of stuff that sent me to WTL.

If i've got a cstring variable that holds for example:
"cat\r\nmouse\r\ndog"
how can i split them into 3 separate cstring variables that contain just cat, mouse and dog respectively. Do i need GetBuffer to do this? If so, how do you specify the right size?
Thanks.

Pretty easily, actually.
CString1 s1 = "cat\r\nmouse\r\ndog";
CString sCat, sMouse, sDog;
sCat = s1.Left(3);
sMouse = s1.Mid(5,5);
sDog = s1.Right(3); Of course this relies on the fact that you know where the texts are within the string. if you want to just seperate them into three strings based on cr/nl:
CString1 s1 = "cat\r\nmouse\r\ndog";
CString s2, s3, s4;
s2 = s1.SpanExcluding("\r\n");
s1 = s1.Right(s1.GetLength() - (s2.GetLength() + 2));
s3 = s1.SpanExcluding("\r\n");
s4 = s1.Right(s1.GetLength() - (s3.GetLength() + 2)); Again, this assumes many things, but I think you get the idea that there are lots of ways to attack this problem.

It's useful sometimes to use internal function AfxExtractSubString (which is defined in afxwin.h and implemented in winstr.cpp).
It's prototype is:
BOOL AFXAPI AfxExtractSubString(CString& rString, LPCTSTR lpszFullString, int iSubString, TCHAR chSep = '\n');
so it works only with one-character separators.
With the best regards, Vitaly.

or copy the cstring into a char array (standard string) and use strtok()

Hi there All,
Changing Text in Statics and controls at run time ?
Well i'm trying to do something which i'm sure its possible and i dont know how.
Actually i want to make a loop (which loop ??)through all the Controls and Windows
under an SDI project and change all the labels of the controls\windows
(including the static ones).
How can this be done,
I'll apritiate any help,
Ariel.

When you say all the controls, what controls ? An SDI app has toolbar(s), a menu, but do you have controls embedded into your view, or in your toolbars ? Do you want to change YOUR items, or those provided by MFC ? The way to change the text is SetWindowText, the way to get ahold of an item you don't own ( for example if you subclass a common dialog ), is GetDlgItem, but I'm not sure how you would iterate through a dialog in a loop, unless you called GetDlgItem for ALL possible ID's and check for a valid return before calling SetWindowText.

How can I execute a SQL command using the OLE DB Consumer Templates? I don't want anything complicated like returning data, I just want to do a bunch of INSERT and UPDATE statments at once.

This was based on one of the MSDN samples. You have to have an open CDataSource.
HRESULT CAbstractDatabase::ExecuteSQL( LPCTSTR pszSQL, BOOL bShowErrors /* = TRUE */ )
{
// DataSource object must be initialized.
HRESULT hr;
if( m_DataSource.m_spInit.IsEqualObject( NULL ))
return E_INVALIDARG;
CSession conn;
CCommand<cnoaccessor,cnorowset,cnomultipleresults> cmd;
// Open session using datasource.
hr = conn.Open( m_DataSource );
if( FAILED(hr) )
{
if(bShowErrors)
DisplayOLEDBErrorRecords( hr );
return hr;
}
// Open command using session.
hr = cmd.Open( conn, pszSQL );
if( FAILED(hr) )
{
if(bShowErrors)
DisplayOLEDBErrorRecords( hr );
}
// Close command and session and return result.
cmd.Close();
conn.Close();
return hr;
} // ExecuteSQL

Dear all,
How can I declare a variable so that all cpps in my MFC project can access the
variable?
Thanks.

in whatever.h:
extern int myGlobalVariable;
in whatever.cpp
int myGlobalVariable = 0;
in any file you want to use myGlobalVariable:
#include "whatever.h"
-c

I can't get it work even I have followed what you'd said, since there are many others header files included in my cpps. Will this be the reason leading to my errors?
Thanks a lot!

Be sure to include the header with the 'extern' wherever you are going to use it. Or stick the header include in your stdafx.h

Like this (applies to C++ not just MFC):
yourcode.h:
extern globalVariableType YourGlobalVariable;
yourcode.cpp:
globalVariableType YourGlobalVariable;
This is freqently use for making the MFC CWinApp class global like this:
extern CMyApp theApp;
(this is because theApp is already defined in your MyApp.cpp file by MFC). This nicely replaces:
((CMyApp*)AfxGetApp())->Bogus();
with:
theApp.Bogus();
Hope this helps

IE programming is one area that I am lacking, so I have to ask: What is the easiest way (if any way) to obtain the text in an running separate instance of IE's window? In this case, it would be the text from controls that are of the "Internet Explorer_Server" window class.
The end result would be a call that I could make that would populate a buffer with all of the text (or up to a specified amount of text) in that control instance.
This would be similar to a cut and paste operation, but without involving the standard clipboard (ie, would not trash any existing text in CF_TEXT format that is already there).
Can this be done?
-=- James.

i might be tempted to grab the stuff off the clipboard into a buffer then send a few messages to the ie window to select all and copy ... then grab that text into another buffer and restore the first buffer
prolly a better way but ie stuff isnt my strong point either

I would be too, but:
o The "Internet Explorer_Server" window does not respond to WM_COPY or EM_SETSEL messages
o That would cause a visual "blip" on the target window, which is undesired.
But thanx for the response, anyway.

I'd like to program a ftp-server.
Can anyone tell me, what i have to do
in order to set up one?
A little bit c++ code or a link
would be nice...
thanks...

well foxy its not quite so simple unfortunately.
"a bit of code ... would be nice..." would amount to a few thousand lines of code at the least.
maybe you should research the basic stuff of network programming, multi-threading and the ftp protocol as a good start.
its not rocket science in theory but getting a good ftp server that actually works and is scalable, robust and efficient is a bit of an art.

Can anyone tell me if the following code is correct:
class CMyPropertySheet : public CPropertySheet
{
// ...
public:
virtual int DoModal();
protected:
static int CALLBACK PropSheetProc( HWND hwndDlg, UINT uMsg, LPARAM lParam );
}
class CMyDialogTemplate : public CDialogTemplate
{
friend CMyPropertySheet;
}
int CMyPropertySheet::DoModal()
{
m_psh.dwFlags |= PSH_USECALLBACK;
m_psh.pfnCallback = PropSheetProc;
return CPropertySheet::DoModal();
}
int CALLBACK CMyPropertySheet::PropSheetProc( HWND hwndDlg, UINT uMsg, LPARAM lParam )
{
switch ( uMsg )
{
case PSCB_PRECREATE:
{
LPDLGTEMPLATE pTemplate = ( LPDLGTEMPLATE )lParam;
CMyDialogTemplate dlgTemplate;
dlgTemplate.m_hTemplate = ::GlobalHandle( pTemplate );
dlgTemplate.m_dwTemplateSize = CMyDialogTemplate::GetTemplateSize( pTemplate );
dlgTemplate.SetFont( _T("Tahoma"), 8 );
dlgTemplate.Detach();
break;
}
default:
break;
}
return 0;
}
I am in doubt if it is allowed to modify property sheet template this way.
Although I have tried it out on NT4 and everything looked just fine.

Nikolay

Small question... Why not use SetFont in the CPropertyPage-derived class(es)? You can use it in CPropertyPage::OnInitDialog(...). You can set the font for the dialog, and its controls right there.
-=- James.
|
|
|
|
|
Because I set the desired font for my CPropertyPages in the Resource Editor (although MFC ignores font settings for CPropertyPages in the Resource Editor  , it could be easily solved by overriding CPropertySheet::BuildPropPageArray()), and at run-time, I want to set the sheet's FONT to be the same and SIZE everything correctly.
Unfortunately, the Windows Property Sheet control was designed so that it always uses the system font for the sheet. So the problem is that I need to specify somehow the desired font for the CPropertySheet itself. Above is my solution.
Regards,
Nikolay

Does anyone know how to create a property sheet then create it in a Dialog Bar (DIFFERENT THEN A DIALOG!) I've been have problems doing this in MFC. Thanks
