The DdeKeepStringHandle function increments the usage count associated with the specified handle. This function enables an application to save a string handle passed to the application's dynamic data exchange (DDE) callback function. Otherwise, a string handle passed to the callback function is deleted when the callback function returns. This function should also be used to keep a copy of a string handle referenced by the CONVINFO structure returned by the DdeQueryConvInfo function.
BOOL DdeKeepStringHandle(
| DWORD idInst, | // instance identifier |
| HSZ hsz | // handle to string |
| ); |
Parameters
idInst
Specifies the application instance identifier obtained by a previous call to the DdeInitialize function.
hsz
Identifies the string handle to be saved.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
