setStoreHandle Method
[This feature was first implemented for MSXML 5.0.]Sets a certificate store handle on the signature object, so that certificate information can be inserted into the <ds:KeyInfo> element.
This method is callable in C/C++ applications only.
C/C++ Syntax
HRESULT setStoreHandle (void* hCertStore);
Parameters
- hCertStore
- Handle to a certificate store created using CryptoAPI functions, such as
CertOpenSystemStoreorCertOpenStore.
Return Values
- S_OK
- Certificate store handle was set without error.
- E_FAIL
- Failed to set the certificate store handle.
Remarks
Calling this method releases all the certificates previously assigned to this object.
Example
The example below is functionally similar to the store property example. It shows the effect of setting the certificate store on an IXMLDigitalSignatureEx object by calling the setStoreHandle method. When a signature is signed without calling this method and the CERTIFICATES flag is set in the call to the sign method, the resultant signature document contains the certificate of the key used in sign. However, when the signature is signed after this method is called to set the certificate store, the resultant signature document contains all the certificates in the store, in addition to the certificate of the key used in sign.
In this example, the certificate store has three certificates. So the signed signature document contains four <ds:Certificate> entries, two of which are identical.
