You haven't included the header file...

I have included the header file in both the files

UpdateDlg.h

#include "StatusDlg.h" // Added by ClassView
#include "CreateDlg.h" // Added by ClassView

// UpdateDlg.cpp : implementation file
//

#include "stdafx.h"
#include "DesktopSearch.h"
#include "StatusDlg.h"
#include "CreateDlg.h"
#include "UpdateDlg.h"
#include "FoldersDialog.h"

Why? Including in the header file is enough!

Whats type CCreateDlg?
and (you wrote)CCreateDlg *m_dCreateDlg; then you should use m_dCreateDlg->DoModal(); ~~m_dCreateDlg.DoModal();~~

parichaybp,

I think this code dont work because you declare
CCreateDlg *m_dCreateDlg;

[I think you get a error like this the variable m_dCreateDlg is begin used without.....]

and I again repeat question
whats type CCreateDlg ? (example in header file -> Is class CCreateDlg : public CDialog?or....)

parichaybp10-Apr-06 22:53

10-Apr-06 22:53

CreateDlg is Dialog window its same as UpdateDlg both the dialog window i have added using add resources...

well,

-------------In Main File CssDlg-------------------------
#include "test2.h"

....

private:
class CTest2;
//Then declare a pointer:
CTest2 *m_dlg;

---------------------------
void CssDlg::OnBnClickedButton3()
{
m_dlg.DoModal();
}

d:\Projects\ss\ssDlg.cpp(418): error C2228: left of '.DoModal' must have class/struct/union type

then I use

void CssDlg::OnBnClickedButton3()
{
m_dlg->DoModal();
}

d:\Projects\ss\ssDlg.cpp(418): error C2027: use of undefined type 'CssDlg::CTest2'

d:\Projects\ss\ssDlg.cpp(418): error C2227: left of '->DoModal' must point to class/struct/union

I find your problem delete
private:
~~class CTest2;~~//Then declare a pointer:
CTest2 *m_dlg;
--------------------------------------
and you should CTest2 m_dlg;
Now It's work

you are declaring the pointer in the CreateDlg file for the dialog
That should be done in UpdateDlg.h
that's all

enums

Hi,

I have a small problem when using enums with VC++. Although, I use enums a lot with C#, I am having problems using them in VC++. Let me explain.

I have the declaration in the header file:

class CContext  <br />
{<br />
private:<br />
<br />
public:	<br />
	enum ContextType<br />
	{<br />
		Context1 = 0,<br />
		Context2<br />
	} ;<br />
<br />
        CContextMenu() ;<br />
	virtual ~CContextMenu() ;<br />
        bool AddContextItems( ContextType cT ) ;<br />
};

Then I have the implementation in the cpp file:

bool AddContextItems( ContextType cT )<br />
{<br />
        //Do something	<br />
	return true ;<br />
}

But on compilation, I get the error, ContextType undeclared identifier.
Also, when I click on the function AddContextItems in the Workspace explorer window, it says, Cannot find defination(Implementation) of this file. Can you tell me why this happens?

Thanks,

You hvn't given semi colon after(;) the class declaration.
just a guess!

Although it compiling fine now, I still get the cannot find declaration(implementation) of this file error.

Also, when I try to use the function from another class, I get the error,
error LNK2001: unresolved external symbol "public: bool __thiscall CContext::AddContextItems(enum CContext::ContextType)" (?AddContextItems@CContext@@QAE_NW4ContextType@1@@Z)

Can anyone help me decrypt this mumbo jumbo.... ?

I just can't figure out, what the error means? Smile | :)

the error comes beause there is no implementation for the function CContext::AddContextItems..

Plz check the cpp that the AddContextItems funtion is written as same as wrote below. I think u haven't noticed the item i have marked bold ..

bool CContext::AddContextItems( CContext::ContextType cT )
{
//Do something
return true ;
}
