QuerySiblings() does not return a value that can be cast to a CString.

If page two wants to know the name that was selected on page one, store that name in the sheet (the common link between pages).

You can also go around with this using CString if you are using MFC
Define the structure as:
struct row{
CString name;
CString sex;
};
// In your code where you are retrieving the string you can write:
char *CampID=new char[50];
GetDlgItemText (IDC_MYEDIT,CampID,50);
row r;
r.name =(CString )CampID;
AfxMessageBox (r.name); // r.name has same string as CampID

Somethings seem HARD to do, until we know how to do them.

Hi,

I want to validate a CEdit control in a property page, I use CEdit::OnKillFocus event. when the user switches to another page ane the contents are invalid I need to force the property sheet to return to the page that includes the invalid data, so how can this be done??

plus, is there a special place (OnValidate) to place my code in instead of placing validation code in KillFocus event???

thanx alot

Mohammad

You can handle validations in CPropertyPage::OnKillActive.

this is my code :

void CNcontabile::OnChangeName()
{

CString sCod ;

m_city.GetWindowText(sCod);

CDatabase_Mag* pMag = new CDatabase_Mag();

pMag->SetRowsetSize(25);

if (!pMag->Open())
return;
if (pMag->IsOpen())
{

while(!pMag->IsEOF())

if( sCod == pMag->m_mag)
{
m_name.SetWindowText(pMag->m_den);

}

}

pMag->Close();
}
m_name = CEdit;
m_city = CEdit;

Yes- you're searching in memory, after reading it all. You need to create a SQL query that returns only the data you're looking for.

David has given you a generic select statement. We can't do more than that because

a - we don't know your SQL schema ( or even what sort of DB it is )
b - we can only guess as to what classes you're using for database connectivity.

Are those REALLY database names, or are they field names in your code, which have been auto generated for you ?

Do you know what SQL is ? Do you know what technology you're using to connect to your database ? Do you know what sort of database it is ?

CEdit *Display;
Display = reinterpret_cast<cedit *="">(GetDlgItem(IDC_EDITCAMPAIGNID));
Display->SetWindowText("tejaswini");

CComboBox *Combo;
Combo = reinterpret_cast<ccombobox *="">(GetDlgItem(IDC_COMBOFORMAT));
Combo->SetWindowText("shilpa");
Combo->AddString("Radhika");
Combo->AddString("Lakshmi");

But when i executed the program I am getting only "Lakshmi" in the dropdown list.How can I get "Radhika" also in the drop down list.

or if you have the id of the edit control and no variable associated to it...
GetDlgItemText()
or use SendMessage() etc...

if you have a variable of CEdit you can use from it m_Edit.GetWindowText(...); if you have ID of control you can use GetDlgItemText for text and GetDlgItemInt for number Smile | :)

Why suggest this when CString is preferable? Allocating memory is expensive. Unnecessarily interacting with the memory manager is just asking for trouble.

Had you used a CEdit member variable, one line of code would be all that's necessary.

Are you sure, its not getting added?.I dont see any problem with code.
