Modless dialog box puzzlement....
Have a DLL class dynamically linked to the MFC.
This class is nothing more than a processing class so has no window associated with it.
I would however like a dialog & progress bar to display visually what is going on as some of the data files that will be loaded are big and time consuming.
I tried to use a modeless dialog box but keep getting the error:
ERROR: Cannot find dialog template with IDD 0x2713.
I've double checked the directories and all files are there , included in the project and the dialog box is available for editing.
Here are some relevant code snippets?. Any suggestions as to where I could have screwed up???
Resource .h
//{{NO_DEPENDENCIES}}
// Microsoft Developer Studio generated include file.
// Used by SimplyClass.rc
//
#define IDC_PROGBAR 10000
#define IDD_PROGDLG 10000
#define IDC_PROGRESS1 10003
#define IDD_SHOWACTS 10003
// Next default values for new objects
//
#ifdef APSTUDIO_INVOKED
#ifndef APSTUDIO_READONLY_SYMBOLS
#define _APS_NEXT_RESOURCE_VALUE 10004
#define _APS_NEXT_COMMAND_VALUE 32772
#define _APS_NEXT_CONTROL_VALUE 10004
#define _APS_NEXT_SYMED_VALUE 10000
#endif
#endif
Declaration:
class CModless : public CDialog
{
// Construction
public:
CModless(CWnd* pParent = NULL); // standard constructor
// Dialog Data
//{{AFX_DATA(CModless)
enum { IDD = IDD_SHOWACTS };
// NOTE: the ClassWizard will add data members here
//}}AFX_DATA
}
Constructor:
CModless::CModless(CWnd* pParent /*=NULL*/)
: CDialog(CModless::IDD, pParent)
{
//{{AFX_DATA_INIT(CModless )
// NOTE: the ClassWizard will add member initialization here
//}}AFX_DATA_INIT
if (Create (CModless::IDD,pParent) )
ShowWindow(SW_SHOW);
}
Implementation:
CModless* WinShow = new CModless();
Thanks..

Checked that out but...the resource is in the DLL project itself,and included in the project directories,
Should I move it??
I'm confused about the Cannot find dialog template message as the files are all there.

ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Since it appears that you did not make the DLL an extension DLL, the AFX_MANAGE_STATE(...) approach is the way to go.
Place this line as the first line in any function that access a resource. It will take care to reset the resource handle back when the function ends.

Q: is the error a compilation, link or run-time error?
AfxSetResourceHandle(AfxGe
You night also have to save the current resource handle using AfxGetResourceHandle() and restore it later.
