I've created an MFC-dll.
Now I want to execute the app inside the dll. Which program do I have to use for that? Rundll.exe, Rundll32.exe (what's the difference)?
Or are there any other programs?
This is what I did (and it didn't work  ):
Inside vc6 I pressed ctrl-f5 to run the app, a popup appeared requesting a dll-executer. I browsed to windows/rundll32.exe and selected it. But the dll was never executed.
What am I doing wrong?

Do you want to run a specific function exported from your dll?

syntax : rundll32 DllName,FunctionName [Arguments]
Where FunctionName is an entry-point (any function) with the following prototype :
void CALLBACK EntryPoint(
HWND hwnd,
HINSTANCE hinst,
LPTSTR lpCmdLine,
int nCmdShow
);
Interesting stuff is that WinMain() has this prototype too, but this was easily predicted.
MSDN doc[^]
rundll.exe is the former 16-bit counter part (now legacy).
If the DLL is an in-proc COM component, you may instead use the DllHost.exe surrogate process, though it works differently.

I'm calling rundll from VC6.
So the settings are:
Executable for debug session:
c:\windows\rundll32.exe
Working directory:
empty
Program arguments:
empty
Remote executable and path name:
empty
Where do I have to put the functionname?
Is it fn() or just fn without ()?
I don't have to state the dll-name, isn't it?
btw:
I've tried several combinations, but none of them work.
I can switch to release version if debug doesn't work.

The functionname should be put in the Program arguments field, (may be with additional quotes to make sure that space chars are properly interpreted).
Your operating system already uses many times rundll32.exe xxx, so I guess this could help you figuring it out. Just do a search in the registry!

I entered this: ,functionname
whithout quotes or brackets, like it's defined in .def file.
Now rundll says that it cannot find the path to other dll's needed by my dll (mfc dll's I guess). But they are probably in windows\system directory.
I've also tried to enter my projects pathname, but that doesn't make any difference.
and another question:
I saw once that dll's are called by the RunDll-function, instead of the WinMain-function for regular apps. Is that true? Can't find it anymore.

These are my codes about printing bitmap:
<br />
CDC dc;<br />
CPrintDialog printDlg(FALSE);<br />
if (printDlg.DoModal() ==IDOK)<br />
{<br />
dc.Attach (printDlg.GetPrinterDC());<br />
DOCINFO di;<br />
memset(&di,0,sizeof(DOCINFO));<br />
di.cbSize =sizeof(DOCINFO);<br />
di.lpszDocName ="ͼÏó´òÓ¡";<br />
CString filename="MONEY.bmp";<br />
HBITMAP bmp=NULL;<br />
bmp=(HBITMAP)LoadImage(NULL,filename,IMAGE_BITMAP,0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION);<br />
<br />
CBitmap bitmap;<br />
bitmap.Attach (bmp);<br />
BOOL bPrintingOK = dc.StartDoc(&di);<br />
CPrintInfo Info;<br />
Info.m_rectDraw.SetRect(0,0, dc.GetDeviceCaps(HORZRES), dc.GetDeviceCaps(VERTRES));<br />
StartPage(dc);<br />
<br />
<br />
CDC dcMemory;<br />
dcMemory.CreateCompatibleDC(&dc);<br />
<br />
dcMemory.SelectObject(bmp);<br />
BITMAP bm;<br />
bitmap.GetBitmap(&bm);<br />
<br />
dc.StretchBlt (0,0,bm.bmWidth,bm.bmHeight,&dcMemory,0,0,32,32,SRCCOPY);<br />
EndPage(dc);<br />
EndDoc(dc);<br />
DeleteDC(dcMemory);<br />
dc.Detach ();<br />
}<br />
DeleteDC(dc);<br />
<br />
The compiler told me there are 0 errors,but I can't see the bitmap appear on the paper after the program is executed.Why?

This is the classic case of trying to print a device-dependant bitmap (DDB). What you need to do is to convert the bitmap to a device-independant bitmap (DIB) before you print it. There are articles on www.codeguru.com[^] describing it and probably also here somewhere...
Look at the bitmap section[^] at codeguru for some code.

Can you help me with this program
Write a program to implement "Add to save" feature to a document. Hint: Use Timer event

Hint:
Use SetTimer and if using MFC use OnTimer function to handle event.
If using WTL create a OnTimer message cracker.

Are you thinking of a tabbed view (PropertyPages) or of a splitter view, which has a bar between two views (like windows explorer)

The idea is the same, u just have to modify it in a way that the driver is pointing to your SQL server and not Excel

Hello there,
I used to below function to add string to RichEdit box, it works fine on Win98 or WinXP ... but it has bug in Win2000 !
Function:
void CResultDialog::AddText(CString str, COLORREF rgb, BOOL bold, BOOL italic, BOOL underline)
{
// get current length from rich text box ...
int nCurLen = m_Rich.GetTextLength();
// hide selected text !
m_Rich.HideSelection(TRUE, FALSE);
// move the cursor to end of rich control ...
m_Rich.SetSel(nCurLen, nCurLen);
// attach the new string to the last of rich edit ...
m_Rich.ReplaceSel(str);
int nStartPos = nCurLen;
int nEndPos = m_Rich.GetTextLength();
// configure the character format !
CHARFORMAT2 cf;
cf.cbSize = sizeof(CHARFORMAT2);
cf.dwMask = CFM_COLOR | CFM_BOLD | CFM_UNDERLINE | CFM_ITALIC;
cf.dwEffects = (unsigned long)~(CFE_ITALIC | CFE_UNDERLINE | CFE_BOLD | CFE_AUTOCOLOR);
cf.crTextColor = rgb;
cf.dwEffects |= underline ? CFE_UNDERLINE : cf.dwEffects;
cf.dwEffects |= bold ? CFE_BOLD : cf.dwEffects;
cf.dwEffects |= italic ? CFE_ITALIC : cf.dwEffects;
// select added text ...
m_Rich.SetSel(nStartPos, nEndPos);
// use character format !
m_Rich.SetSelectionCharFormat(cf);
m_Rich.SetSel(-1, -1);
}
I used this function in here:
AddText( "Company: ", RGB(255, 0, 0), TRUE, FALSE, FALSE );
AddText( "Microsoft", RGB(0, 0, 0), TRUE, FALSE, FALSE );
AddText( "\nContact: ", RGB(255, 0, 0), TRUE, FALSE, FALSE );
AddText( "Billi", RGB(0, 0, 0), TRUE, FALSE, FALSE );
AddText( "\nWeb: ", RGB(255, 0, 0), TRUE, FALSE, FALSE );
AddText( "www.m$.com", RGB(0, 0, 0), TRUE, FALSE, FALSE );
It has bug in Win2000,
The bug is colors on the text ...
I think it's because my enter character in my strings ...
Win98 or WinXP count enter character in for getting lenght but Win2000 doesn't it, or vice versa !
How can i solve it ??
