In my PropertyPage header I have this declaration:
#include "CookItDBDoc.h"
// CSpecial2Page1 dialog
class CSpecial2Page1 : public CBCGPPropertyPage
{
DECLARE_DYNAMIC(CSpecial2Page1)
public:
CSpecial2Page1();
//CWnd* pParent = NULL, int nDlg = 0, CString csDlgName = ""); // standard constructor
virtual ~CSpecial2Page1();
void RetFromGetSpecialMealDlg(CString csFileName);
// Attributes
public:
CCookItDBDoc* GetDocument() const;
...
}
============> in .cpp file <========================
void CSpecial2Page1::RetFromGetSpecialMealDlg(CString csFileName)
{
m_csFileName = csFileName;
FileReadCatMenuXML(m_csFileName);
FileReadSpecialMenuXML(m_cMenuData.m_csFullFilePath);
CSpecial2* pPS = (CSpecial2*)GetParent();
pPS->SetSpecial(m_cSpecialData);
pPS->SetMenuData(m_cMenuData);
SetDlgItemText(IDC_SELDRINKS,m_cSpecialData.m_csSpecialOccassionName);
FileReadDrinkMenuXML(m_cSpecialData.m_csDrinkFilePath);
InsertItemsDrink();
GetDocument()->OnNewSpecialDrink(m_vDrink, m_cSpecialData.m_csSpecialOccassionName);
}
the error is this:
1>Linking...
1>Special2Page1.obj : error LNK2019: unresolved external symbol "public: class CCookItDBDoc * __thiscall CSpecial2Page1::GetDocument(void)const " (?GetDocument@CSpecial2Page1@@QBEPAVCCookItDBDoc@@XZ) referenced in function "public: void __thiscall CSpecial2Page1::RetFromGetSpecialMealDlg(class ATL::CStringT<char,class StrTraitMFC<char,class ATL::ChTraitsCRT<char> > >)" (?RetFromGetSpecialMealDlg@CSpecial2Page1@@QAEXV?$CStringT@DV?$StrTraitMFC@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@@Z)

I thought maybe I had mispelled something so I checked:
in Doc header:
void OnNewSpecialDrink(CDrinkDataVec vData, CString csMealPlan);
in Doc cpp:
// CCookItDBDoc commands
void CCookItDBDoc::OnNewSpecialDrink(CDrinkDataVec vData, CString csMealPlan)
{
m_vDrink = vData;
CDrinkData cData;
int nIndex = 0;
int nTotal = m_vDrink.m_vDrinkData.size();
.....
}
the problem is with this:
GetDocument()->OnNewSpecialDrink(m_vDrink, m_cSpecialData.m_csSpecialOccassionName);
specifically this:
CCookItDBDoc* GetDocument() const;
I do NOT understand why this is so does anyone else?

Your CSpecial2Page1 is apparently derived from a class you derived from CPropertyPage, and that class does not have a GetDocument method.
Unless you've defined that method in your CBCGPPropertyPage class, it doesn't exist and that's why you get the error.

I thought by my putting the #include CCookItDBDoc.h in the prpopertyPage header that I would be able to jump to a function(Non-static) within the CCookItDBDoc class. I guess you can't do it that way. How would you do it?

Including the header only provides the declaration of the class. Non-static members do not actually exist except within an instance of the class itself.
You probably already have a document instance (CYourAppDoc) somwhere, so you need to provide a pointer to that existing instance in order to use its methods. The existing instance contains all of the variables (with their appropriate values), so if you were to create a new instance in your propert page class, it would be a different instance with different values.
One way this is done with a dialog box would be to have a button that you click to create the dialog and the handler for that button is in the document. The dialog header file might contain something like
CYourAppDoc* m_pMyDocPtr; Then when the button is clicked the handler (in the doc class) might have something like this:
CMyDialog myDlg;
myDlg.m_pMyDocPtr = this;
myDlg.DoModal()
Now in the dialog, you can access the doc data and methods by using
m_pDocPtr->DocFunction1();
Hope that helps.

Yes, I know that, but how would I do that with a CDocument and a CPropertyPage?

The principal is still the same - pass a pointer to your document into your property pages. You may want to pass it to the property sheet and then have the sheet pass it to the pages. If you create your pages/sheet from a view, your view probably also has a pointer to the document.
Good luck.

Can any one tell me what is the mistake i have did in below line of code?
int iPrimaryLang[4]={LANG_ENGLISH, LANG_BENGALI, LANG_ORIYA, LANG_HINDI};
I am getting compiler error C2059, C2334.

Hi,
You might also post the code above.
I think (based on error C2334 ) you missed ': or {'; somewhere.
At least google tells you that: http://msdn.microsoft.com/en-us/library/f0swb231.aspx[^]

It might be an idea to quote more of the error than just its code. Not all of us have comitted them to memory. Make it easy for people to answer your question and more people are likely to reply.

I compiled this code. I did not get any error message. Did you include right header files?

Hi,
when I have videofiles or JPEG-pictures displayed in "Large Icon" mode in XP explorer, I get a detailed preview for each single file, showing its content. I'd like to have the same for my own custom filetype that my application uses. I have already googled, but keep failing to get the right keyword to use how I can do that myself, using VC++ and MFC.
Do you have any suggestions?
Thanks alot!

it is somethink with Shell, it will be really annoying and awksame. I have read (here) that it got chnaged between XP and Vista/7.
look here and search preview:

Hi,
thanks alot, but I think that's not what I really need, I want a thumbnail preview in explorer that Windows XP already offers for variuos filetypes, for example JPEG pictures: when I set the view to icons or tiles in explorer, I see a real preview of the image inside. My application is some sort of a CAD program with its own filetype, and I would like to render preview thumbnails the same way.
How is it done in explorer? How can I make it work the same way as for JPEGs in XP and Vista?

Maybe take a look at this[^] for starters.

There are in header files or in MSDN such windows errors starting from 0xC.

There's even a website with that name [^] (i.e. Have you googled for?).
