Hi all,

I wrote a dll (using a definition file). When I call one of the function within the dll from another application (to test the function), I receive a strange error (Messagebox format): Application.exe - Ordinal Not Found - The ordinal 34 could not be located in the dynamic link library. Note I have linked with the .lib file, have included the header file and copied the .dll file to the application directory. (Note that I'm exporting 34 functions)

O.K futher testing has shown that the error only occurs with the last three functions. Does this Confused | :confused:

help??

Can anyone help??

Thanx

Use dependency walker, to see if all exported functions you can see in exported functions list. I know this is not going to help, but this is just to check whether everything is alright while exporting.

Well thanx for the reply Prasad.

I use dependency walker alot and if I could paste a pic here you would see that all the functions are displaying and looks correct.

I'm not using a class with all these functions, would there be like a limit on the amount of functions one can export. (Which I don't think would be the case) ??

Quick google search suggest, problem occurs when newer version is required( function called is not present in dll).
Can you show how you called this function.

Ok, this is what I did in my test application (who's calling the dll).

Included the header file.
Under properties -> link added the .lib file.
Copied the .dll file to the root folder of the application.

<code>
bool retcode = fasle;
char* proc_name = "c:\\program files\\winamp\\winamp.exe";
retcode = createAProcess(proc_name);
if (retcode)
{
  ....
</code>

After all of this I receive the error mentioned earlier.

If this might help, I did a dumpbin /exports on the dll and the result is shown below:

It looks ok.
I feel , you are missing something very simple. Just last try, make sure, you rebuild you dll with added functions. make sure you copy updated .lib and .dll in correct folder.

Thank you for the help Prasad, someone else gave me the same answer on the MSDN forum and I got it working.

Hi Friends,

Following error is troubling me from last couple of days, I am looking for some help from the group

I am doing following steps:

1. Adding a dialog box with ID=IDD_DLG_ORG_IMAGE in the SDI application
2. Adding class using class wizard with class name ‘COrgImgDlg’ derived from ‘CDialog’ for the above created dialog
3. After Compiling a code I am getting following error

--------------------Configuration: IP - Win32 Debug--------------------
Compiling...
MyTabCtrl.cpp
e:\dinesh\ip\orgimgdlg.h(23) : error C2065: 'IDD_DLG_ORG_IMAGE' : undeclared identifier
e:\dinesh\ip\orgimgdlg.h(23) : error C2057: expected constant expression
Error executing cl.exe.

IP.exe - 2 error(s), 0 warning(s)

Following is the part of the orgimgdlg.h file where I am getting error

class COrgImgDlg : public CDialog
{
// Construction
public:
COrgImgDlg(CWnd* pParent = NULL); // standard constructor

// Dialog Data
//{{AFX_DATA(COrgImgDlg)
enum { IDD = IDD_DLG_ORG_IMAGE };
// CMyTabCtrl m_ImageTabs;
//}}AFX_DATA

Please help me out I am not understating why this error is occurring in the same header file of the dialog.

Thanks and Regards,
-Dinesh

Check whether, dilaog you wnat to base class upon is having id IDD_DLG_ORG_IMAGE .
And resource.h is included appropriately .

What #include directives do you have at the top of orgimgdlg.cpp and orgimgdlg.h?
