Parameters

formTemplateLocation

Exceptions

If the form template that currently exists in the cache matches the form template from the published location, no caching takes place. If the computer is offline and the form is already in the cache, the cache is kept and no update will occur.

This member can be accessed only by forms opened from a form template that as been configured to run with full trust using the Security and Trust category of the Form Options dialog box.

This type or member can be accessed only from code running in forms opened in Microsoft Office InfoPath 2007.

{ 
   @"\\MyServer\MyForms\MyForm.xsn", 
   @"\\MyServer\MyForms\manifest.xsf" 
};

private void someFunction()
{
...
   CacheMyFormTemplates(_forms);
...
}

private void CacheMyFormTemplates(string[] forms)
{ 
   foreach (string form in forms)
   {
      this.Application.CacheFormTemplate(form);
   }
}
