Hello!
First: Thank you!
But I still have problems with printing from the List Box. Particularly: What do I have to write into the functions: OnBeginPrinting, OnPrint, OnEndPrinting. Must I change something in the Print-function?
Can anybody help me more exactly? I only want to print the content (CStrings) of a ListBox from a dialogbased programm.
Thank you very much! 
Have a nice day!

For very simple printing, you can leave the OnBeginPrinting() and OnEndPrinting() functions blank. You can do all your printing in OnPrint().
Simply use CListBox::GetText() to get the strings from the listbox, and CDC::DrawText() to print the strings onto the printer. Just be sure to update the rectangle that DrawText() uses so that you do not print all the strings on top of each other. The CPrintInfo::m_rectDraw variable contains the coordinates of the printable portions of the page.

Hello!
I'm sorry, but I still have problem with the printing functions. The member-variable of my ListBox is m_ctrlListBox.
I wrote in the OnPrint(CDC *pDC, CPrintInfo* pInfo)-function:
CString s;
m_ctrlListBox.GetText(0,s);
CRect g(2,2,2,2) ;
pDC->DrawText(s,g,DT_LEFT || DT_TOP);
The problem: My print is empty!
Can anybody help me??
Thank you very much.

The first thing that comes to mind is that your CRect g is too small. you are trying to draw the text into a 2x2 pixel area. The second is to make sure that GetText() is actually getting the text and that CString s is not empty.
try CRect (0,0,pInfo->rectDraw.right, pInfo->rectDraw.bottom);

Hello!
Thank you very much, it works! ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
Now I have the next Problem:
Only the first CString is printed, but I want to print the whole content of the ListBox.
First I made a for statement:
CString test;
int anz=m_ctrlListe.GetCount();
for(int i=0;i<anz;i++)
{
this-="">m_ctrlListe.GetText(i,test);
CRect g( 750,750,pInfo->m_rectDraw.right,pInfo->m_rectDraw.bottom);
pDC->DrawText(test,g ,DT_LEFT || DT_TOP );
}
It is logical, that only the last entry is printed.
How must I update the CRect to print the whole content of the ListBox.
Thank you very much!
Have a nice day.

DrawText() returns the height of the text drawn, so simply increase g.top by that value before you draw the next line.

Hello!
I still have another problem:
for (UINT page = Info.GetMinPage();
page <= Info.GetMaxPage() && bPrintingOK;
page++)
{
dc.StartPage();
Info.m_nCurPage = page;
OnPrint(&dc, &Info);
bPrintingOK = (dc.EndPage() > 0);
}
Info.GetMaxPage returns the value 65535.
But in my example it must be only one site.
If I set page=1, it works. But maybe later I want to print more pages.
Where can the mistake be?
Thank you very much.

If that's all you want to do, and don't need ano of the "fancy" GDI stuff, just open LPT1: and write the chars to it.

Hi there,
In a dialog based application, I need create a window with spliter
control. In the creation of the MSVC Formview class, i find a debug error:
"Error: Dialog with IDD 0x%04X must have the child style" (lpszResource).
Where can i set this style?
This is also the problem I required last night with detailed source code.

Thanks for all the replys!
Best regards,

In the dialog resource editor:
Rightclick - Properties - Styles tab - Style Combobox - bottom of the list

open the dialog in the resource editor. open the properties dialog; there is a drop down list of styles to choose from; "child" is one (popup is another)

This one has been driving me mad for hours. I should have stopped to ask for help a long time ago.
Under certain circumstances I am unable to open the clipboard after using keybd_event to send a synthesized ctrl-c keystroke. (here's how i'm using keybd_event)
keybd_event(VK_CONTROL, 0, 0, 0);
keybd_event('C', 0, 0, 0);
keybd_event('C', 0, KEYEVENTF_KEYUP, 0);
keybd_event(VK_CONTROL, 0, KEYEVENTF_KEYUP, 0);
if (OpenClipboard())
...etc
The circumstances under which OpenClipboard fails is if I have previously opened the clipboard and have "pasted" text into it with the CopyStringToClipboard() function below. (Here are both of the clipboard functions i'm using)
void CClipboardDlg::CopyCurrentClipboardText()
{
if (OpenClipboard())
{
HANDLE hClipboardData = GetClipboardData(CF_TEXT);
char * pchData = (char*)GlobalLock(hClipboardData);
CString strFromClipboard = pchData;
GlobalUnlock(hClipboardData);
CloseClipboard();
}
}
<BR><BR>
void CClipboardDlg::CopyStringToClipboard()
{
CString strData;
m_ClipboardStringList.GetText((m_iClipboardListPosition), strData);
if (OpenClipboard())
{
if (::IsClipboardFormatAvailable(CF_TEXT)||
::IsClipboardFormatAvailable(CF_OEMTEXT))
{
HGLOBAL hClipboardData;
EmptyClipboard();
hClipboardData = GlobalAlloc(GMEM_DDESHARE, strData.GetLength() + 1);
char * pchData;
pchData = (char*)GlobalLock(hClipboardData);
strcpy(pchData, LPCSTR(strData));
GlobalUnlock(hClipboardData);
SetClipboardData(CF_TEXT, hClipboardData);
}
CloseClipboard();
}
}
The strange thing is before I ever call CopyStringToClipboard() I can open the clipboard before and after the keystroke just fine. After calling CopyStringToClipboard() I can open the clipboard fine before sending the keystroke but not afterward. Stranger still, if I send the keystroke twice (not in code, but say, by a registered hotkey that calls the function) then it works fine for the second and for every subsequent keystroke until I call CopyStringToClipboard() again! It's only that first keystroke after calling CopyStringToClipboard() that behaves badly.
My first suspicion was I wasn't allowing enough time between sending the keystroke and attempting to open the clipboard but I found that waiting 5000 ms was the minimum time until the clipboard could be opened. That is beside the fact that everything works fine until CopyStringToClipboard() gets called.
I eagerly await enlightenment with my open hand poised in front of my forehead and the word "DOH" on the tip of my tongue.

Given an existing .mdb database, I want to change the Password every time I close the database.
Ideas

class CMyDaoDatabase : public CDaoDatabase
{
// ....
virtual ~CMyDaoDatabase()
{
// 1. random gen new password.
// 2. set the new password into the MDB file
// 3. save the new password into register or file
// (maybe before saving, you can encode the password)
}
};
