ImportFromFile Method
Loads a certificate from a file.
Syntax
int ImportFromFile(const QString& qsPath, const QString& qsPassword);
Remarks
This method can load certificates saved in one of the following formats: DER, PEM, PFX, SPC.
Use the Path parameter to provide a path to the certificate, and Password to specify the password. The Password parameter is optional. If it is omitted and it is later discovered that the certificate is password-encrypted, the PasswordNeeded event will be fired to request it.
Error Handling
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
