Public MustOverride Sub CacheFormTemplate ( _
    formTemplateLocation As String _
)
'Usage

public abstract void CacheFormTemplate(
    string formTemplateLocation
)

Parameters

• formTemplateLocation
  Type: System.String

  Specifies the Uniform Resource Identifier (URI) of the form template. This parameter can be specified as a form definition (.xsf) file or a form template (.xsn) file.

Exceptions

Exception	Condition
FileNotFoundException	The form template file cannot be found.

ArgumentException	The parameter passed to this method is not valid. For example, they are of the wrong type or format.

Remarks

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 has been configured to run with full trust using the Security and Trust category of the Form Options dialog box. This member requires full trust for the immediate caller and cannot be used by partially trusted code. For more information, see "Using Libraries from Partially Trusted Code" on MSDN.

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

private string[] _forms = 
{ 
   @"\\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);
   }
}
