IWMSContext.CopyValues (C#)

The CopyValues method copies specified values to another context.

Syntax

Parameters

pDest

IWMSContext object to copy the values into.

pstrName

Reference to a string array containing the names of the attributes to copy. This can be set to null.

lNameHint

Reference to an Int32 array containing the corresponding optional key values of the values to copy. This can be set to null.

lNames

int the count of values to be copied. This can be set to zero.

Return Values

This method does not return a value.

If this method fails, it throws an exception.

Number Description
0x80070057 pDest is not a valid context.

Remarks

Specifying a value of zero for the lNames parameter will copy the entire context to the destination context.

Example Code

Guid ContextGuid = typeof(IWMSContext).GUID;
IWMSContext     Context;
IWMSContext     CopyContext = null;
IntPtr          pUnknown;
int             iHint = 0;
string          strName = "";

try
{          
    m_ClassFactory.AllocIWMSContext(ref ContextGuid,
                                   WMS_CONTEXT_TYPE.WMS_USER_CONTEXT_TYPE,
                                   pUserContext, out pUnknown);
    Context = (IWMSContext)Marshal.GetTypedObjectForIUnknown(pUnknown,
                                                     typeof(IWMSContext));
            
    Context.SetStringValue(WMSDefines.WMS_CONTENT_DESCRIPTION_TITLE,
                           WMSDefines.WMS_CONTENT_DESCRIPTION_TITLE_ID,
                           "My Title", 0);
    Context.SetLongValue(WMSDefines.WMS_CONTENT_DESCRIPTION_NO_SKIP,
                         WMSDefines.WMS_CONTENT_DESCRIPTION_NO_SKIP_ID,
                         1, 0);

    Context.CopyValues(CopyContext, ref strName, ref iHint, 0);
}
catch( Exception e )
{
    // TODO: Handle exceptions.
