The GetNextForm continues the custom forms enumeration started with GetFirstForm. HRESULT GetNextForm( [out] LPWSTR* p_pwsFormName, [out] LPWSTR* p_pwsFormDescription, [out] FLOAT* p_pfWidth, [out] FLOAT* p_pfHeight, [out] BOOL* p_pbVisible );
Parameters: p_pwsFormName [out]pointer to a pointer to a null terminated Unicode string that will contain the name of the custom form. The allocated memory must be freed by the caller with CoTaskMemFree p_pwsFormDescription [out]pointer to a pointer to a null terminated Unicode string that will contain the description of the custom form. The allocated memory must be freed by the caller with CoTaskMemFree p_pfWidth [out] will contain the width of the form in millimeters p_pfHeight [out] will contain the height of the form in millimeters p_pbVisible [out] will be TRUE if this form is visible in the printing preferences dialog
Return values: S_OK on success or COM error code NV_NOT_INITIALIZED - Initialize was not called NV_ENUM_NOT_INIT - GetFirstForm was not called NV_NO_MORE_FORMS - no more forms to enumerate
Remarks: GetFirstForm along with GetNextForm are used to enumerate all custom forms like in the code sample below: hr = GetFirstForm(&pName, ...) while (SUCCEEDED(hr) && hr != NV_NO_MORE_FORMS) { // do something with pName, and the other parameters // ... CoTaskMemFree(pName); // get next form if it exists hr = GetNextForm(&pName); } |
