SetIcon Method

Selects a registered overlay icon for display on the virtual drive in Windows Explorer.


int SetIcon(const char* lpszIconId);
INT SetIcon(LPCWSTR lpszIconId);


This method selects the overlay icon specified by IconId for display, causing it to be shown on the virtual drive in Windows Explorer. The desired icon must have already been registered using the RegisterIcon method, and the value passed for IconId must match the one passed RegisterIcon at that time.

To switch to a different overlay icon later, call this method again with a different IconId. To reset the virtual drive's icon back to its default state (i.e., displayed without any overlay icons), call the ResetIcon method. Please refer to the Custom Drive Icons topic for more information.

The Helper DLL must be installed in order for this method to function correctly. Applications can check to see whether the Helper DLL is installed using the GetModuleVersion method, and install it using the Install method if necessary.

Note: This method can only be called after creating a virtual drive, and cannot be called within events. Also, note that the effects of this method only last until the virtual drive is destroyed; applications that always want to have some overlay icon displayed must call this method each time the virtual drive is created.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
