UINT GetDlgItemInt( int nID, BOOL* lpTrans = NULL,
BOOL bSigned = TRUE ) const;
Parameter Description
<nID> Specifies the integer identifier of the dialog-box item to
be translated.
<lpTrans> Points to the Boolean variable that is to receive the
translated flag.
<bSigned> Specifies whether the value to be retrieved is signed.
Remarks
Translates the text of the specified control in the given dialog box
into an integer value.
Retrieves the text of the control identified by <nID>. It translates the
text by stripping any extra spaces at the beginning of the text and
converting decimal digits, stopping the translation when it reaches the
end of the text or encounters any nonnumeric character.
If <bSigned> is TRUE, GetDlgItemInt checks for a minus sign (-) at the
beginning of the text and translates the text into a signed number.
Otherwise, it creates an unsigned value.
Sends a ◄WM_GETTEXT► message to the control.
Return Value
Specifies the translated value of the dialog-box item text. Since 0 is a
valid return value, <lpTrans> must be used to detect errors. If a signed
return value is desired, cast it as an int type.
Zero if the translated number is greater than 32,767 (for signed
numbers) or 65,535 (for unsigned).
When errors occur, such as encountering nonnumeric characters and
exceeding the given maximum, GetDlgItemInt copies 0 to the location
pointed to by <lpTrans>. If there are no errors, <lpTrans> receives a
nonzero value. If <lpTrans> is NULL, GetDlgItemInt does not warn about
errors.
