Parameter |
Description |
|
hWnd |

Value |
Meaning |
|
VECTOR_DLG_ENABLE_HELPBUTTON |
[0x00000002] Enable Help button. |
pfnCallback |
Pointer to an optional help callback function. |
|

If you do not wish to provide help to this dialog, use NULL as the value of this parameter. |
|
|
To provide help to this dialog, use the function pointer as the value of this parameter. |
|
|
The callback function must adhere to the prototype described in LVCOMMDLGHELPCB. |
|
pUserData |
Void pointer that you can use to pass one or more additional parameters that the callback function needs. |
|
|
To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. |
