If the connect string varies depending on location the app is running
from, then you need to provide the correct connect string instead of
hard-coding the string.

GetDefaultConnect() is virtual. Simply derive a class from CRecordset
and override GetDefaultConnect() to return an appropriate string.
That's great for one recordset, but it's much easier to manage connections
with CDatabase - the class that actually represents the database connection.
You can have multiple connections (CDatabase Objects) so you can pool connections.
CDatabase MyDatabase;
BOOL ret;
try
{
ret = MyDatabase.OpenEx(myconnectionstring, CDatabase::noOdbcDialog);
}
catch(CDBException *e)
{
return;
}
if (ret && MyDatabase.IsOpen())
{
CMyRecordset myRecordset(&MyDatabase);

Is there a way to retreive the data entered in a Edit Control Box while using a numerical Type variable? I've seen lots of examples that retreive the data when the variable Type is a CString, but none when it is numerical. In my dialog box I've got a Edit Control Box and I've added a variable of integer type so the number entered could be retreived without doing a conversion. But the value is always zero no mater what is entered. The following is some of the code:
Edit_Numbers_Dlg::Edit_Numbers_Dlg(CWnd* pParent /*=NULL*/)
: CDialog(Edit_Numbers_Dlg::IDD, pParent)
{
//{{AFX_DATA_INIT(Edit_Numbers_Dlg)
m_entered_number = 0;
//}}AFX_DATA_INIT
}
void Edit_Numbers_Dlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(Edit_Numbers_Dlg)
DDX_Text(pDX, IDC_ENTERED_NUMBER_EDIT, m_entered_number);
DDV_MinMaxInt(pDX, m_entered_number, 0, 999999);
//}}AFX_DATA_MAP
}
void Edit_Numbers_Dlg::SearchNumbers()
{
for( int z=0; z<counter-1; z++="" )<br="" mode="hold"> {
if( oldnumbers[z] == m_entered_number )
found = 1;
}
}

Yes. Use GetWindowText(), followed by atoi().

Isn't GetWindowText() and atoi() for string types?

Edit controls contain only text, thus to get an integer you must get the text and convert it.

Not true. If you work with a CEdit* and Get/SetWindowText then is ok what you say. But you can also associate a numeric member variable to the edit in the resource editor and it works as well.
HEADER
enum { IDD = IDD_MYFORMVIEW};
double m_dMyDouble;
CPP
void CMyFormView::DoDataExchange(CDataExchange* pDX)
{ CFormView::DoDataExchange(pDX);
DDX_Text(pDX, IDC_MY_EDIT, m_dMyDouble);
}
With this you will be able to work directly with numbers. And still more, if you make it like that, the edit will give you an error itself when you are introducing letters.
PS. This is under MFC (VC++ 6.0)

It's only text. MFC converts it to a numeric value, but the control stores only text. Next time, please actually look at what the source code is doing.

From OP: Is there a way to retreive the data entered in a Edit Control Box while using a numerical Type variable?
Ok, it is the MFC who converts to numeric, but the OP is using MFC and having problems to associate the edit to a numeric variable... so the fact is, that he actually can do it.

Your code should work. Did you call UpdateData(TRUE) to retrieve the data from the control?
Edit: Actually, your for loop is incomplete.

Although my answer[^] has been downvoted, you may want to check it. The other answers about get the data in string format and then convert it are totally correct, but you can make what you were asking as well.

GetWindowText() would not work with a type of int or cstring. Debug always showed the value was 0 though I'd entered 123456. So I've changed the category to Control and the type is CEdit. This is what I'd been doing earlier in the code and used the following code to get and convert the entry.
m_entered_number.GetWindowText( temp_CString );
entered_number = atoi( temp_CString );
Was looking for a way to eliminate the string and conversion but VS does not want to cooperate.
Everyone, thank you for you help.

You are using it wrongly. If you declare the member variable as numeric then you can not use it. (see my downvoted answer)
If you want to use that functions you have to declare the member variable as CEdit.
Or do it programmatically:
CEdit* pEdit = GetDialogItem (IDC_MYEDIT);
pEdit->GetWindowText (strTemp);
number = atoi (strTemp);
PS: I don't have VC++ in this laptop and I don't remember if the function is GetDialogItem or GetDlgItem. Check you local help, it anyways is a member function of CDialog

you forget to give call to UpdateDate(false) function which retrieve values from dialog box back to variable

Hello dear friends,
I've created a .docx file programatically but opening this file says that
the file has been currupted.
Here is the code.
unsigned long nSize = 0;
char szBuffer[100];
CFile o;
CFileException e;
strcpy(szBuffer,"hi");
nSize=strlen(szBuffer);
if(!o.Open("C:\\Documents and Settings\\Rigel\\Desktop\\Exl.docx", CFile::modeCreate | CFile::modeWrite,&e))
{
MessageBox("Can't open the file for writing.",_T("File"),MB_OK);
}
else
{
o.Write(szBuffer,nSize);
o.Close();
}
ShellExecute(NULL,"open","C:\\Documents and Settings\\Rigel\\Desktop\\Exl.docx",NULL,NULL,SW_NORMAL);
Help me please.

Well, of course, if you just put a string in the file without respecting the file format. A doc (and docx) file is a binary file, so you have to respect the format of that file. I know that you can use automation to create doc file but I don't know if the format is the same as a docx file.

Of course not, docx file is an XML file.
