You'll want to create the processes with CreateProcess(). Then you'll want to read what is written to the STARTUPINFO.hStdOutput handle.

See if MSDN article Q190351 helps.

Just search for Q190351. It's a fairly unique "word" in and of itself.

Oh so is that I will use that standard input and output handles in the Windows API program? Bcoz I see both of the programs there in the source codes are main(), so I am not sure if it is redirecting the I/Os from console to the windows API.

Actually I'm quite new to windows API, so plz forgive my ignorance if I have asked some very dumb questions. Big Grin | :-D

OK...I think I have resorted to use a individual window for a program

I mean one window application for one console program...

But I still have problems even making that....how do I ouput the text?
I know I have to use the function TextOut but ...should I simply replace all the "printf" with "TextOut" or there is extra workings?

Thanz!! Smile | :)

Need to create Document and Excel in vc++

6-May-03 16:14

Anyone got any idea of how to group these windows together? Like the "tile" action of the window or sth...I really want to group the 6 windows...at least closer I mean...it's really ugly and messy to have 6 console windows spreading all over the screen....

Thanz really!! Smile | :)

unicode

How would one add unicode support to a text editor control that uses CString for a buffer?

Would the control already have implicit unicode support?

GDI functions like DrawText() will automatically be converted to DrawTextW or DrawTextA depening on _UNICODE define???

I've never bothered much with unicode and figure i should start Smile | :)

Thanks

There's lots of good tutorials on Unicode and Windows programming. Check those out, but basically you would define _UNICODE in your Project/Settings, and in place of "char" use "wchar_t", and string literals have "L" before them (e.g., L"a string"). But the best way is to use the "tchar.h" file's macros so that you don't have to change your source code when you change back and forth from _UNICODE to _MBCS. (use "TCHAR" instead of "char", and wrap string literals with the _T() macro (e.g., _T("a string")).

Use OLE Automation. Here's an Excel example:

_Application    app;
Workbooks       books;
_Workbook       book;
Worksheets      sheets;
_Worksheet      sheet;
Range           range;
COleVariant     vtOptional((long) DISP_E_PARAMNOTFOUND, VT_ERROR),
                vtTrue((short) TRUE),
                vtFalse((short) FALSE);
CString         strText;


if (app.CreateDispatch("Excel.Application") == TRUE)
{
    app.SetVisible(TRUE);

    books = app.GetWorkbooks();

    book = books.Add(vtOptional);

    sheets = book.GetSheets();

    sheet = sheets.GetItem(COleVariant((short) 1));

    range = sheet.GetRange(COleVariant("A1"), COleVariant("A1"));
    m_ebCellA1.GetWindowText(strText);
    range.SetValue(COleVariant(strText));

    range = sheet.GetRange(COleVariant("A2"), COleVariant("A2"));
    m_ebCellA2.GetWindowText(strText);
    range.SetValue(COleVariant(strText));

    range = sheet.GetRange(COleVariant("A4"), COleVariant("A4"));
    range.SetFormula(COleVariant("=A1 + A2"));
}

Here's a Word example:

CString         strFileName;
_Application    app;
Documents       docs;
_Document       doc;
COleVariant     vtOptional((long) DISP_E_PARAMNOTFOUND, VT_ERROR),
                vtFalse((short) FALSE),
                vtTrue((short) TRUE);


if (app.CreateDispatch("Word.Application") == TRUE)
{
    docs = app.GetDocuments();

    m_ebDocName.GetWindowText(strFileName);

    doc = docs.Open(COleVariant(strFileName), vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional);

    doc.PrintOut(vtFalse, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional);

    while (app.GetBackgroundPrintingStatus() > 0)
        ;

    docs.Close(vtFalse, vtOptional, vtOptional);

    app.Quit(vtOptional, vtOptional, vtOptional);
}

I agree - Automation is a way. BUT don't forget COM - it's much easier and less complicated then the snippets.

COM hides all the details.

If you are interested - contact me for an example using COM.

Automation and COM are not mutually exclusive. Remember that Automation is a technology based on the Component Object Model, that enables interoperability among components such as ActiveX. It makes it possible for one application to manipulate objects implemented in another application, or to "expose" objects so they can be manipulated by another.

You could use ODBC and treat EXCEL sheets like tables.

Hi,
Is there any way in which I could get all the controls that exist in a Dialog?
I went through most of the functions in CDialog and CWnd but couldn't find any.

Thanks in advance,
Melwyn

This is how we have to do.
Read it, understand it and learn your self.

CWnd *pWnd = m_pPropertySheet->GetWindow(GW_CHILD);
CWnd *pWnd1 = NULL;
CWnd *pWnd2 = NULL;
CString cstrCaption;
while(pWnd) //get all the controls on the property sheet
{
pWnd->GetWindowText(cstrCaption);
if( _T("OK") == cstrCaption ) //get one with caption "OK"
pWnd1 = pWnd;
if( _T("Cancel") == cstrCaption )//get one with caption 'Cancel"
pWnd2 = pWnd;
pWnd = pWnd->GetNextWindow(); //go to next control
}
if( pWnd1)
{
pWnd1->DestroyWindow(); //remove OK button
}
if( pWnd2)
{
pWnd2->DestroyWindow(); //remove Cancel button
}
m_bOKCancelRemoved = TRUE;

A little more friendly answer would be to look at the EnumChildWindows function. Let's say that you need to grey out all items on the dialog except the cancel button. This code would do that:

CMyDialog::DisableAllControls()
{
EnumChildWindows(GetSafeHwnd(),MyDisableProc,this);
}

// this is a static member fcn
BOOL CMyDialog::MyDisableProc(HWND hWnd, LPARAM lParam)
{
- CMyDialog *pDlg = (CMyDialog *)lParam;
-
- if (::GetDlgCtrlID(hWnd) != IDCANCEL)
- ::EnableWindow(hWnd,FALSE);
-
- return TRUE;
}

Hi basementman,
Thanks for giving me an alternative solution.
Your example makes it very clear.

Any idea how EnumChildWindows()is different from a GetWindow()+FindWindow() loop?

Thanks and Regards,
Melwyn
