Re: why can i only see "index,left,...."these strings i set when i set point's parameter negative?

Its the way a window display works. The top left corner is 0,0. So when plotting on your screen display it falls outside the clipping region in use and is not shown. During print preview, no clipping region is in force, and point 0,0 is still in the top left of the page, but at the start of the printable area of the page (i.e. indented by the margin amounts).

Your string at (20, -20) is off the top on screen
but visible in print preview due to the extra canvas and lack of clipping region

I'm sure there was a class on CP that can load Unicode text, try to search. Underneath, the is no easy way to do it - you simply load portion-by-portion, analyzing content. Unicode file can start with signature (FFFE or FEFF) - this will help to to understand what you have. But it is not required - in this case you will have to try to detect if text is unicode (see ::IsTextUnicode()). As for displaying, it depends on your project - if it is Unicode-enabled, then no problems. Otherwise you will need to convert to plain text.

Well thanks,
but I also have a problem with displaying the text (_UNICODE is defined on my project). I can display the UNICODE text only with AfxMessageBox , when I try to set a STATIC TEXT control value to that text it does not show it correclty . Also wprintf(...) is not working .

Why do i get in Windows 98 GetClipboardSequenceNumber undeclared identifier?

RegisterShellFilesType(TRUE) for a dialog box based on CRichEditCtrl gives me a debug
assertion failed: appui2.cpp line 191. I find ASSERT(m_pDocManager != NULL); and
m_pDocManager is CDocManager variable type which is a derived class from Object, but what is
CDocManager and what do i have to do in order not to appear this assert?I get this message after i close my app.
How ca I implement MRU list in a dialog box?I know about CRecentFileList, but how can i do it because i need a menu item?
Where I can have the mfc faq?
And please don't tell me about CRichEditView , I already know about it but I can't re-write my entire app because it is quite complex.
I have the following code for Find/Replace , but it doesn't working and not even the selection is not working as it should be.

bool CMyRtfDlg::FindWhatYouNeed( bool bMatchCase, bool bMatchWholeWord, bool bSearchDown)
{
FINDTEXTEX findText;
findText.lpstrText = (LPTSTR) (LPCTSTR) findName;
findText.chrg.cpMin = 0;
findText.chrg.cpMax = -1;
int nLen=findName.GetLength();
long lResult = m_rtf.FindText(0, &findText);
CString s;
s.Format("%d",lResult);
SetWindowText(s);
if (lResult == -1)
{
MessageBox("No matches!");
bSearchDown = false;
return false;
}
else
{
m_rtf.SetSel(lResult,nLen);
bSearchDown=true;
//findText.chrg.cpMin = lResult + 1;
//long lResult = m_rtf.FindText(0, &findText);
}
return true;

}
Thanks a lot.

I assume you have the right .h files included. Do you have WINVER defined? If not, take a look at line #4389 of wsinuser.h.

I want to write OPC client application...I collected some information on it...The information is...to write OPC client application i have to buy OPC client Toolkit which contains COM based interface...and used it with c++ or Visual basic....
Now I want to know that is this information correct?...plz help

Well, I seriously doubt about it. OPC is just a standard set of interfaces, used for hardware/software communication. All you need is description of interfaces, which you can easily get in internet. However, that toolkit may contain templates and test application, which you will find extremely usefull during development. But maybe such tester and sample is available in internet too, see http://www.opcfoundation.org/

__cdecl, from MSDN:

"This is the default calling convention for C and C++ programs. Because the stack is cleaned up by the caller, it can do vararg functions. The __cdecl calling convention creates larger executables than __stdcall, because it requires each function call to include stack cleanup code. The following list shows the implementation of this calling convention."

3 months ago I started writing an VC6-ActiveX-project. I choosed to have Runtime License in the project-startup-Wizard.

Now I’m trying to publish it on the net but it will not work. I’ve managed to create an ActiveX in .NET with no Runtime Licence and after creating a CAB-project of my .ocx it all worked on the net…
(All clients that didn’t have the .NET-ActiveX got it to work but not the one with Runtime License created in VS6.)

For me very strange…

Is it possible to take away the Runtime License setting from my old ActiveX-project?

It can be a little temperamental, especially with custom classes.

Why not try a third-party product called Visual Assist? I've used it for a long time now and just couldn't live without it - check it out at www.wholetomato.com, the latest version is called "Visual Assist X", you can trial it for 30 days free. It offers boat-loads more features than the standard VC++ 6.0 IDE.

I agree. The built in intellisense in VC6 just plain sucks. It is very slow at times and often quits working at all. Try visual assist. It fixes all these problems.

printing a diialog and its controls

hi,
Im developing a VC++ application in which one requirement is to print the dialog with its control(basically edit box and static text).
Im using the followinf code for this purpose.

CPrintDialog printDlg(FALSE, PD_ALLPAGES | PD_RETURNDC, NULL);<br />
     // Initialize some of the fields in PRINTDLG structure.<br />
     printDlg.m_pd.nMinPage = printDlg.m_pd.nMaxPage = 1;<br />
     printDlg.m_pd.nFromPage = printDlg.m_pd.nToPage = 1;<br />
     // Display Windows print dialog box.<br />
     printDlg.DoModal();<br />
     // Obtain a handle to the device context.<br />
     HDC hdcPrn = printDlg.GetPrinterDC();<br />
     if (hdcPrn != NULL) {<br />
          CDC *pDC = new CDC;<br />
          pDC->Attach (hdcPrn);      // attach a printer DC<br />
          pDC->StartDoc("job");      // begin a new print job<br />
          pDC->StartPage();          // begin a new page<br />
          Print(pDC,PRF_CHILDREN|PRF_CLIENT|PRF_ERASEBKGND);<br />
          pDC->EndPage();            // end a page<br />
          pDC->EndDoc();             // end a print job<br />
          pDC->Detach();             // detach the printer DC<br />
          delete pDC;<br />
     }

The problem im facing is that the content of the print is very small.Any idea where im wrong.I need help to print in a enlarged mode(i.e)bigger print

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
