There was no such error number.

It is debug assertion failed in winfrm and in some other cpp files.

I want to execute my code with no prior links or dependencies, that is why I created a new MFC project in VC++ 2005 and added existing header and source files to it.

Can you show the full call stack at the point the problem occurs, I think you will find that the error occurs before winfrm.cpp which is just complaining that something has not been set up correctly.

Can you post any of the code, or the code with any company confidential information removed, then I can take a look.

Take Project Properties.
From there.
Configuration Properties->C++->Command Line
add the specified switch inside that.

I figured this out a long , i'm sorry i did'nt post it quick.

It seems for VC express you have to download the PSDK(platform SDK) which enables one to write old win32 code.

Theres a whole video on how to integrate the PSDK into VC express , here is it[^]

I got VS pro , the PSDK is integrated into it.

How to get data from a database into a control of property page

Hi,
These r the steps I followed and created the project.

I have created a msaccess database with two tables employee and department.
Created a UserDsn in Administrative (odbc)tools and given the name SampleDB.

1)started visualstudiodeveloper6.0.
New->MFC Appwizard (exe)->ODBCSample->OK
2)Single document ->Next
3)Database view without filesupport->DataSoruce->ODBC->SampleDB->employee->Next->Deselected printing and printpriview->Next->Next->Selected Cview->Finish->OK.
4)Insert->Resource->Dialog->New
5)changed th caption to Data entry and ID to IDD_DATAENTRY and changed properties styles as child and thin.Deselected the systemmenu.
6)Added three static texts and three Edit boxes named as EMPNAME,EMPID,SALARY.
7)Activated the classwizard and added new class CdataEntryDlg ok.Then manually I changed the CDialog to CPropertyPage in DataEntryDlg.h and DataEntryDlg.cpp
7)Inserted new dialog resuorce and changed the properties to child and thin and given the name List and ID to IDD_LIST.
8)Dragged three static texts and editboxes
9)Activated classwizard and given the name CListDlg and Base class as CpropertyPage.
10)Then added new class named CPropSheet.
11)In the resources editor expand menu and double click on IDR_Main menu and in the Help menu I added psheet and activated classwizard and added function.to the MainFrm.cpp
12)In that function added body as
void CMainFrame::OnHelpPsheet()
{
CPropSheet psheet("sheet");
CDataEntryDlg dlg;
CListDlg Ldlg;

psheet.AddPage(&dlg);
psheet.AddPage(&Ldlg);
psheet.DoModal();
}
And included the header files #include “PropSheet.h”
#include “DataEntryDlg.h”
#include “ListDlg.h”
13)Insert new resource ->add new class named as CEmpSet (base class Crecordset) and OK.
Selected ODBC as SampleDB(snapshot) then list of table names displayed and selected employee and then OK.

14)again goes to DataEntry dialog and activated the classwizard.
15)And chosen the class info propertypage and selected the foreign class as CEmpSet and added variable m_pSet then OK.
16)Again moved to DataEntry dialog and activated classwizard and mapped the fields .
17) I included EmpSet.h in DataEntryDlg.h file.

Now I compiled successfully and when executing I got assertion failure.
Please can U say what is the wrong with me.

If I comment out the DDX mechanism in the EmpSet.cpp file then the Propertysheet will be created without any values.

Thank u.
Tejaswini.

You can do it using CPropertySheet::SetWizardButtons with PSWIZB_DISABLEDFINISH, take a look here:

Creating a check nox is the same way as a button only the dwStyle changes:-

myButton.Create(_T("Check  button"), WS_CHILD|WS_VISIBLE|BS_AUTOCHECKBOX, <br />
   CRect(10,100,100,130), NULL, 1100);

Activating global function

AlonYair9-Jul-06 20:05

9-Jul-06 20:05

Hi,
I'm trying to activate a global function for several times (template function).
The only way I can figure how to do it is through a global variable, e.g.:
int dummy = SomeGlobalFunc();
I've wrapped this global variable definition with a preprocessed macro because I want to call the global function several times and for that I need to define a different global variable each time.
The problem is how to define a global variable with a different name each time (I can't use the predefined __COUNTER__ of VS beacause I need this code to be portable).

thanks,
Alon.

Maybe you can define your macro without the unneeded variable:

#define GLOBAL_CALL SomeGlobalFunc();

Even if the return value is not saved, the global function will be called.

You can also try this:

#define GLOBAL_CALL { int dummy = SomeGlobalFunc(); }

I hope this helps.

It's not that I need the return value of the global function, but because C++ doesn't support calling global functions I'm doing a little bypass by defining a global variable and initializing it by calling to the required function.
About the second idea, I thought it was a good idea too to define the global variable in a seperated scope and that way to prevent the need of defining different name for each global variable, but... the compiler decieded to yell that it's not possible defining seperated scope under the global scope.

Re: Activating global function

Viorel.9-Jul-06 23:40

In case of file level calling, I think you can try this:

#define MERGE1(a, b)   a##b
#define MERGE(a, b)    MERGE1(a, b)

#define GLOBAL_CALL    static MERGE(dummy, __LINE__) = SomeGlobalFunc();

The __LINE__ macro, in contrast with __COUNTER__, seems to be portable.

I hope it helps.
