IEnumCERTVIEWCOLUMN::Reset method (certview.h)

The Reset method moves to the beginning of the column-enumeration sequence.

Syntax

HRESULT Reset();

Return value

VB

If the method fails, it returns an HRESULT value that indicates the error. For a list of common error codes, see Common HRESULT Values.

Remarks

Upon successful completion of this method, call the IEnumCERTVIEWCOLUMN::Next method to reference the first column in the enumeration. After this second call is made, the information in the column can be obtained by calling one of the following methods:

• IEnumCERTVIEWCOLUMN::GetName: Retrieves the nonlocalized name of the column.
• IEnumCERTVIEWCOLUMN::GetDisplayName: Retrieves the localized name of the column.
• IEnumCERTVIEWCOLUMN::GetValue: Retrieves the data in the column.
• IEnumCERTVIEWCOLUMN::GetType: Retrieves the type of data in the column.
• IEnumCERTVIEWCOLUMN::GetMaxLength: Retrieves the maximum length, in bytes, of the column.

Examples

// pEnumCol is previously instantiated IEnumCERTVIEWCOLUMN object
HRESULT    hr;
LONG        Index;
hr = pEnumCol->Reset();
if (S_OK != hr)
    printf("Unable to reset pEnumCol\n");
    // call appropriate error handler / exit routine
else
{
    // now at the beginning of the columns
    // enumerate each column
    while (S_OK == pEnumCol->Next(&Index))
    {
        // Use each column as needed.
    }
}
