GetDlgItemInt
The GetDlgItemInt function translates the text of a specified control in a dialog box into an
integer value.
UINT GetDlgItemInt(
HWND hDlg,
| // handle to dialog box
| int nIDDlgItem,
| // control identifier
| BOOL *lpTranslated,
| // points to variable to receive success/failure indicator
| BOOL bSigned
| // specifies whether value is signed or unsigned
| );
|
|
Parameters
hDlg
Handle to the dialog box that contains the control of interest.
nIDDlgItem
Dialog item identifier that specifies the control whose text is to be
translated.
lpTranslated
Points to a Boolean variable that receives a function success/failure value.
TRUE indicates success, FALSE indicates failure.
This parameter is optional: it can be NULL. In that case, the function returns
no information about success or failure.
bSigned
Specifies whether the function should examine the text for a minus sign at the
beginning and return a signed integer value if it finds one. TRUE specifies
that this should be done, FALSE that it should not.
Return Values
If the function succeeds, the variable pointed to by lpTranslated is set to TRUE, and the return value is the translated value of the control
text.
If the function fails, the variable pointed to by lpTranslated is set to FALSE, and the return value is zero. Note that, since zero is a
possible translated value, a return value of zero does not by itself indicate
failure.
If lpTranslated is NULL, the function returns no information about success or failure.
If the bSigned parameter is TRUE, specifying that the value to be retrieved is a signed
integer value, cast the return value to an int type.
Remarks
The GetDlgItemInt function retrieves the text of the given control by sending the control a
WM_GETTEXT message. The function translates the retrieved text by stripping any
extra spaces at the beginning of the text and then converting the decimal digits.
The function stops translating when it reaches the end of the text or
encounters a nonnumeric character.
If the bSigned parameter is TRUE, the GetDlgItemInt function checks for a minus sign ( ) at the beginning of the text and translates the text into a signed integer
value. Otherwise, the function creates an unsigned integer value.
The GetDlgItemInt function returns zero if the translated value is greater than INT_MAX (for
signed numbers) or UINT_MAX (for unsigned numbers).

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
