CERT_SELECT_STRUCT_W structure (cryptdlg.h)
The CERT_SELECT_STRUCT structure contains criteria upon which to select certificates that are presented in a certificate selection dialog box. This structure is used in the CertSelectCertificate function.
Syntax
typedef struct tagCSSW {
DWORD dwSize;
HWND hwndParent;
HINSTANCE hInstance;
LPCWSTR pTemplateName;
DWORD dwFlags;
LPCWSTR szTitle;
DWORD cCertStore;
HCERTSTORE *arrayCertStore;
LPCSTR szPurposeOid;
DWORD cCertContext;
PCCERT_CONTEXT *arrayCertContext;
LPARAM lCustData;
PFNCMHOOKPROC pfnHook;
PFNCMFILTERPROC pfnFilter;
LPCWSTR szHelpFileName;
DWORD dwHelpId;
HCRYPTPROV hprov;
} CERT_SELECT_STRUCT_W, *PCERT_SELECT_STRUCT_W;
Members
dwSize
The size, in bytes, of this structure.
hwndParent
A handle to the parent window of any dialog boxes that CertSelectCertificate generates.
hInstance
A handle to the module whose executable file contains the dialog box template.
pTemplateName
If the CSS_ENABLETEMPLATE flag is set in the dwFlags member, set pTemplateName to a pointer to a global memory object that contains the template that DialogBoxIndirectParam uses to create the dialog box. A dialog box template consists of a header that describes the dialog box. The header is followed by one or more additional blocks of data that describe each of the controls in the dialog box. The template can use either the standard format or the extended format.
If the CSS_ENABLETEMPLATEHANDLE flag is set in dwFlags, pTemplateName specifies the dialog box template. pTemplateName is either the pointer to a null-terminated character string that specifies the name of the dialog box template or an integer value that specifies the resource identifier of the dialog box template. If the specifies a resource identifier, its high-order word must be zero and its low-order word must contain the identifier. One way to create this integer value is to use the MAKEINTRESOURCE macro.
dwFlags
This member can be one or more of the following values.
| Value | Meaning |
|---|---|
|
Hide the Properties button. |
|
Pass a hook procedure in pfnHook. |
|
Enable multi-selection of certificates. This option is not currently supported and is ignored. |
|
Show the Help button. |
|
Cause CertSelectCertificate function to call the DialogBoxIndirectParam function to create a dialog box. For more information, see pTemplateName. |
|
Cause the CertSelectCertificate function to call the DialogBoxParam function to create a dialog box. For more information, see pTemplateName. |
szTitle
A pointer to a string that contains the text for the title of the dialog box.
cCertStore
The number of elements in arrayCertStore array.
arrayCertStore
A pointer to the array of certificate stores that the dialog box enumerates and displays the certificates from. The cCertStore member contains the number of elements in this array.
szPurposeOid
A pointer to a string representation of an object identifier (OID) for an enhanced key usage (EKU). If an OID is provided, only certificates that include this EKU will be displayed.
cCertContext
The number of elements in the arrayCertContext array. After the CertSelectCertificate function returns, this member contains the number of certificates that were selected by the user. Currently, only one certificate can be selected by the user.
arrayCertContext
A pointer to an array of CERT_CONTEXT structures. The cCertContext member specifies the number of elements in this array. This array must contain at least one element.
The certificates represented by these structures are selected when the dialog box displayed by the CertSelectCertificate function is initially displayed. Currently, only the first certificate in this array is used. The first certificate in this array will be released with the CertFreeCertificateContext function if the CertSelectCertificate function is successful. If the first element in this array is NULL, no certificates are initially selected in the dialog box.
After the CertSelectCertificate function returns, this array contains the certificates that were selected by the user. Currently, only one certificate can be selected by the user.
lCustData
A pointer to an array of byte values that hold custom data that is passed through to the filter procedure referenced by pfnFilter. This custom data is not used by the CertSelectCertificate function.
pfnHook
A PFNCMHOOKPROC function pointer to the Hook callback function. This function is called before messages are processed by the dialog box. For more information, see Hooks.
pfnFilter
A PFNCMFILTERPROC function pointer to the filter callback function. This is called to determine which certificates will be displayed by the dialog box.
szHelpFileName
A pointer to a null-terminated string that contains the full path to the Help file.
dwHelpId
The context identifier for the topic. For more information, see
WinHelp.
hprov
A handle to the Cryptographic Service Provider (CSP) to use for certificate verification.
Remarks
Note
The cryptdlg.h header defines CERT_SELECT_STRUCT as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
