How to call Dialog window (formed as resource) from a .DLL

[Pavel_47]

No. In OnClose() handler I believe. Of course you add ON_WM_CLOSE() to message map and send WM_CLOSE on OK or Cancel.

You just add to your dialog class this virtual member function:

void PostNcDestroy()
{
    delete this;
}

MSDN provides lots of simple sample projects.

I tried your proposition as I understood it. Unfortunately nothing changed.
Here is declaration of Dialog Class:

#pragma once

// CPixie3_DLG1 dialog

class CPixie3_DLG1 : public CDialog
{
	DECLARE_DYNAMIC(CPixie3_DLG1)

public:
	CPixie3_DLG1(CWnd* pParent = NULL);   // standard constructor
	virtual ~CPixie3_DLG1();

// Dialog Data
	enum { IDD = IDD_DIALOG };

protected:
	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support
	void PostNcDestroy()
	{
		delete this;
	}

	DECLARE_MESSAGE_MAP()
public:
	afx_msg void OnClose();
	afx_msg void OnBnClickedOk();
};

and here is its implementation:

// Pixie3_DLG1.cpp : implementation file
//

#include "stdafx.h"
#include "Pixie3_GUI.h"
#include "Pixie3_DLG1.h"
#include "afxdialogex.h"
#include "vpi_user.h"

// CPixie3_DLG1 dialog

IMPLEMENT_DYNAMIC(CPixie3_DLG1, CDialog)

CPixie3_DLG1::CPixie3_DLG1(CWnd* pParent /*=NULL*/)
	: CDialog(CPixie3_DLG1::IDD, pParent)
{
	vpi_printf("Inside of CPixie3_DLG1 consructor\n");
}

CPixie3_DLG1::~CPixie3_DLG1()
{
}

void CPixie3_DLG1::DoDataExchange(CDataExchange* pDX)
{
	CDialog::DoDataExchange(pDX);
}


BEGIN_MESSAGE_MAP(CPixie3_DLG1, CDialog)
	ON_WM_CLOSE()
	ON_BN_CLICKED(IDOK, &CPixie3_DLG1::OnBnClickedOk)
END_MESSAGE_MAP()


// CPixie3_DLG1 message handlers


void CPixie3_DLG1::OnClose()
{
	// TODO: Add your message handler code here and/or call default

	CDialog::OnClose();
}


void CPixie3_DLG1::OnBnClickedOk()
{
	OnClose();
	CDialog::OnOK();
}

I also tried the second option:

vpi_printf("Initialization starts ...\n");
CWinApp::InitInstance();
CPixie3_DLG1 dlg;
dlg.DoModal();
vpi_printf("Initialization finishes ...\n");
return FALSE;

Unfortunately it doesn't work at all. I think DoModal function cannot be used in my case, where there is no parent window.
Here is CAD tool output window (with vpi_printf function messages):

As you can constate, the dialog constructor didn't accomplish his job (message "Initialization finishes ...\n" didn't appear.
