L_INT LImageViewer::GetBounds (lpRect, uFlags);
Gets the bounding rectangle for the container.
A pointer to a RECT structure to be updated with the bounding rectangle of the container.
Reserved for future use. Pass 0.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
The coordinates of lpRect are relative to the parent window coordinates. If the container window has no parent, the coordinates will be relative to the screen coordinates.
To set the bounding rectangle for the container, call LImageViewer::SetBounds.
Required DLLs and Libraries
This function determines whether the container's client area is different from its parent's.
