The alternative is to write a wrapper function for the one you're trying to use, which detects the OS version and if it's Win2000/XP or later, gets the address of the function from USER32 and calls it, otherwise does nothing.
Your problem is two things;
You don't have the function declaration unless you have _WIN32_WINNT set to 0x0500, and with that in place, you have a reference to the function in your EXE.
When the EXE runs on an earlier (NT,9x) system, the function cannot be located by the import lib code you pulled in when you built.
You can either do what Stephane suggests, what I suggest, or not use the function

hi all,
can u please tell the function to get the application path in MFC
|
|
|
|
|
char strAppPath[256];
GetModuleFileName(NULL, strAppPath, sizeof(strAppPath));
|
|
|
|
|
I use follow function:
CString GetHomeDirectory() const
{
TCHAR sFilename[_MAX_PATH];
TCHAR sDrive[_MAX_DRIVE];
TCHAR sDir[_MAX_DIR];
TCHAR sFname[_MAX_FNAME];
TCHAR sExt[_MAX_EXT];
GetModuleFileName(AfxGetInstanceHandle(), sFilename, _MAX_PATH);
_tsplitpath(sFilename, sDrive, sDir, sFname, sExt);
CString rVal(CString(sDrive) + CString(sDir));
int nLen = rVal.GetLength();
if (rVal.GetAt(nLen-1) != _T('\\'))
rVal += _T("\\");
return rVal;
}
Best regards,
Eugene Pustovoyt

I used these set of codes
<br />
CString StrLaunched;<br />
TCHAR szFullPath[MAX_PATH];<br />
TCHAR szDir[_MAX_DIR];<br />
TCHAR szDrive[_MAX_DRIVE];<br />
::GetModuleFileName(NULL,szFullPath,MAX_PATH);<br />
_splitpath(szFullPath, szDrive, szDir, NULL, NULL);<br />
<br />
<br />
cheers,

Can I load a combo box from a id (resource id) to get a CComboBox class, like the CMenu function 'LoadMenu' ???
I want write some code like this, but with a combo box:
CMenu menu;
menu.LoadMenu(ID_MYMENU);
...
--> I want write something:
CComboBox box;
box.xxx(ID_MYBOX);
...
(Does it give any function for 'xxx' ???)
Does it give any function for CComboBox to do this ???

Nice greets, Daniel.

You can enter the combo-box selections in the resource-editor, in the properties of the combo-box control, rider 'Data'.
This is stupid IMHO, as you have one more place to work at if you need to change the combo-box.
Better load strings from the stringtable and add these to your combo-box.
So you see in your code what is added to your combobox and you keep your code free from string constatants.

I can't edit the properties of the combo box in the resource editor, because the combo box is not created on a dialog. The combo box is placed in a command bar and is created with the 'CommandBar_InsertComboBox' function. So, the only thing I have is the ID of the combo box. I can edit the combo box with the 'GetDlgItem' and the 'SendMessage' function, but I use the mfc and so I want use the CComboBox class. So I need a function like 'LoadMenu' for the CMenu class for the CComboBox.

Nice greets, Daniel.

Try :
CComboBox* combo = (CComboBox*) GetDlgItem(YOUR_COMBO_ID);

Thanks!!!

I have no idea about this platform. So all I can say is for the 'real' MFC.
But if you have a CComboBox, you can use AddString(), or CB_ADDSTRING as a message to the control.
For loading all entries at once like a menu, you could load the menu, get the texts, and call AddString()with it in a derived class.

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?

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.
