Hello,
i like to modify the dialog style to WS_CHILD, and need help to do this, reason for that is that i
want to place normal dialog on other dialog as child!

// in OnInitDialog() from the parent dialog:
BOOL CParentDlg::OnInitDialog()
{
   pReportDlg.Create(IDD_REPORT, pParentWnd);
// here i need help, pReportDlg is member of CParentDlg, and i want to place him on 
// CParentDlg as child object, but pReportDlg is shown as normal dialog:
// what params i have to remove from the dialog style:
   pReportDlg.ModifyStyleEx(WS_EX_OVERLAPPEDWINDOW | WS_EX_DLGMODALFRAME, WS_CHILD);
   pReportDlg.ShowWindow(SW_SHOW);
   pReportDlg.SetWindowPos(pComboFileName, 8, cRect.top, cRect.right, cRect.bottom, NULL);
}

thanks in advance

Hello Prasad,
thanks for help, the dialog i now showed with new style, without border etc., also like a child
dialog, but they is showed outside of hims parent stay only to clip the dialog to them...

// CFileDialogReport is inherited from CFileDialog
BOOL CFileDialogReport::OnInitDialog()
{
	const UINT iExtraSize = 220;
	CWnd* pParentWnd = GetParent();
	RECT cRect;
	pParentWnd->GetWindowRect(&cRect);
	pParentWnd->SetWindowPos(NULL, 0,0,cRect.right - cRect.left, cRect.bottom - cRect.top + iExtraSize, SWP_NOMOVE);

	CWnd* pComboFileName = pParentWnd->GetDlgItem(cmb1);
	pComboFileName->GetWindowRect(&cRect);
	pParentWnd->ScreenToClient(&cRect);

	// Position for my new controls(for that child dialog)
	cRect.top += 20;
	cRect.bottom += 120;
	cRect.left += 50;
	cRect.right += 160;

	pReportDlg.Create(IDD_REPORT, pParentWnd);
	pReportDlg.ModifyStyle(WS_OVERLAPPEDWINDOW ,WS_CHILD , SWP_FRAMECHANGED);
	pReportDlg.ModifyStyleEx(WS_EX_OVERLAPPEDWINDOW | WS_EX_DLGMODALFRAME, 
		WS_CHILD ,SWP_FRAMECHANGED);

	pReportDlg.ShowWindow(SW_SHOW);
	pReportDlg.SetWindowPos(pComboFileName, 8, cRect.top, cRect.right, cRect.bottom, NULL);
}

ok, i can set settings in the template to child and without border, but i want to try everything
what is posible to do this to runtime, any idea how to do this now?

Hi,
I solve this now, i forgot to set the parent window ,
before i call ShowWindow(SW_SHOW);
i set the parent for my dialog:

pReportDlg.SetParent(pParentWnd);
pReportDlg.ShowWindow(SW_SHOW);
pReportDlg.SetWindowPos(pComboFileName, 8, cRect.top, cRect.right, cRect.bottom, NULL);

You can mention parent window, at the time of creation only.

Your code looks correct. I did the same thing sans the call to ModifyStyleEx() and the child dialog was definitely contained within the parent. In the child's dialog template, I set the Style to Child, and the Border to None.

Just out of curiosity, why? Do you not have access to the project's .rc file?

Even if you did something like:

ModifyStyle(WS_POPUPWINDOW | WS_CLIPSIBLINGS | WS_DLGFRAME | DS_MODALFRAME, WS_CHILDWINDOW);
ModifyStyleEx(WS_EX_DLGMODALFRAME | WS_EX_WINDOWEDGE | WS_EX_CONTROLPARENT, 0);

there's no guarantee that it will work.

Windows SDK Communication Question

Greetings:

Does anybody know anything about a limit to the COMn designation that can be successfully opened by the "CreateFile" SDK function?

We have serial ports here that can take mappings greater than 9 (ie: COM10, COM11, etc...). "CreateFile" returns NULL for anything greater than COM9.

Does anybody know a way of getting around this?

Its Windows XP-Pro at the moment, but we have to expect our application to run on other versions as well. I'm using VS 2003 and MFC.

Thank you,
Mark

This is special case code (or hack) in the implementation of ::CreateFile() that recognizes the filename "COM" followed by one single integer. You can have COM ports from COM1 to COM255, but for port numbers above 9 you have to use "\\\\.\\COMnnn" as filename, e.g. "\\\\.\\COM10".

ComBSTR Question

Like2Byte19-Feb-07 3:41

19-Feb-07 3:41

Hello everyone,

I'm migrating an MFC application to use a new interface (Old DLL to new OCX). the old interface used _TCHAR, bool, etc..., types. The new interface (OCX) uses VARIANTs - *everywhere*.

here's the problem: We're using a structure to maintain a list of active connections (MAX 10).

/*header file - SANDBOX.H*/
typedef struct SModuleInfo
{
#if 1
/*new*/
  CComBSTR bstrModName[256];
  CComBSTR bstrBinFileName[256];
  VARIANT  vbSelected;  /*T/F - if item was selected
  VARIANT  vModHandle;  /*Module Handle*/
  VARIANT  vModID;  /*Module ID*/
  VARIANT  *m_cpzModName;
  VARIANT  *m_pzBinFileName;
#else
/*old*/
  BOOL  bSelected;  /*T/F - if item was selected
  long  lModHandle;  /*Module Handle*/
  long  lModID;  /*Module ID*/
  _TCHAR  m_cpzModName[256];
  _TCHAR  m_pzBinFileName[256];
#endif
} SModuleInfo_t;


class CSandboxApp : public CWinApp
{
public:
  void ModInfoDestroy();
  bool InitModInfo();
  SModuleInfo_t mods[10];
  CSandboxApp();

// Overrides
   ...

// Implementation
   ...
};

Would the following code be the best way to initialize my structure?

/*SOURCE CODE - SANDBOX.CPP*/

bool CSandboxApp::InitModInfo()
{
  for( short i = 0 ; i < 10 ; i++ )
  {
     mods[i].bSelected.vt = VT_BOOL;
     mods[i].lModHandle.vt = VT_I4;
     mods[i].lModID.vt = VT_I4;
     mods[i].lVdsID.vt = VT_I4;
	
     mods[i].m_cpzModName->vt = VT_BSTR;
     mods[i].m_pzBinFileName->vt = VT_BSTR;
     mods[i].m_cpzModName->bstrVal = mods[i].bstrModName->Copy();
     mods[i].m_pzBinFileName->bstrVal = mods[i].bstrBinFileName->Copy();
   }
   return 1;
}

void CSandboxApp::ModInfoDestroy()
{
   int i = 0;
      for( i = 0 ; i < 10 ; i++ )
      {
         mods[i].bSelected.bVal = FALSE;
         mods[i].lModHandle.lVal = 0;
         mods[i].lModID.lVal = 0;
         mods[i].lVdsID.lVal = 0;
         mods[i].m_cpzModName->bstrVal = NULL;
         mods[i].m_pzBinFileName->bstrVal = NULL;
         mods[i].bstrModName->Empty();
         mods[i].bstrBinFileName->Empty();	
      }
}

Between InitModInfo() and DestroyModInfo() I will be populating mods[i].m_pzBinFileName and mods[i].m_cpzModName with textual data the user will be selecting from a listbox. The other values (longs, bools, etc.) will be filled as appropriate later.

My chief concern is properly maintaining the two BSTR arrays. Can I expect this code to align the data correctly so I can pass the variant String data to a function that takes VARIANTs? I think it is ATL and I've not used it before.

Thanks. Unsure | :~

CComBSTR is a string, so no need to define array.

Modify this to,

   SysFreeString(mods[i].m_pzBinFileName->bstrVal);
