LB_SETCOUNT
An application sends an LB_SETCOUNT message to set the count of items in a
list box created with the LBS_NODATA style and not created with the LBS_HASSTRINGS
style.
LB_SETCOUNT
wParam = (WPARAM) (int) cItems; // count of list box items
lParam = 0; // not used; must be zero
Parameters
cItems
Value of wParam. Specifies the new count of items in the list box.
Windows 95: The wParam parameter is limited to 16-bit values. This means list boxes cannot contain
more than 32,767 items. Although the number of items is restricted, the total
size in bytes of the items in a listbox is limited only by available memory.
Return Values
If an error occurs, the return value is LB_ERR. If there is insufficient
memory to store the items, the return value is LB_ERRSPACE.
Remarks
The LB_SETCOUNT message is supported only by list boxes created with the
LBS_NODATA style and not created with the LBS_HASSTRINGS style. All other list boxes
return LB_ERR.

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 » |
