DdeCreateStringHandle The DdeCreateStringHandle function creates a handle that identifies the string pointed to by the psz parameter. A dynamic data exchange (DDE) client or server application can pass the string handle as a parameter to other Dynamic Data Exchange Management Library (DDEML) functions.

Operating Systems Supported |

Requires Windows NT 3.1 or later; Requires Windows 95 or later |
- idInst
Specifies the application instance identifier obtained by a previous call to the DdeInitialize function.
- psz
Points to a buffer that contains the null-terminated string for which a handle is to be created. This string may be up to 255 characters. The reason for this limit is that DDEML string management functions are implemented using global atoms.
- iCodePage
Specifies the code page used to render the string. This value should be either CP_WINANSI (the default code page) or CP_WINUNICODE, depending on whether the ANSI or Unicode version of DdeInitialize was called by the client application. |
If the function succeeds, the return value is a string handle.
If the function fails, the return value is 0L. |
