LinkToQuery

MailMergeSettings.LinkToQuery property

Not sure about this one. The Microsoft Word Automation Reference suggests that this specifies that the query is executed every time the document is opened in Microsoft Word. But the OOXML specification suggests that this specifies that the query contains a reference to an external query file which contains the actual query. The default value is false.

public bool LinkToQuery { get; set; }

Examples

Shows how to execute a mail merge with data from an Office Data Source Object.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Write("Dear ");
builder.InsertField("MERGEFIELD FirstName", "<FirstName>");
builder.Write(" ");
builder.InsertField("MERGEFIELD LastName", "<LastName>");
builder.Writeln(": ");
builder.InsertField("MERGEFIELD Message", "<Message>");

// Create a data source in the form of an ASCII file, with the "|" character
// acting as the delimiter that separates columns. The first line contains the three columns' names,
// and each subsequent line is a row with their respective values.
string[] lines = { "FirstName|LastName|Message",
    "John|Doe|Hello! This message was created with Aspose Words mail merge." };
string dataSrcFilename = ArtifactsDir + "MailMerge.MailMergeSettings.DataSource.txt";

File.WriteAllLines(dataSrcFilename, lines);

MailMergeSettings settings = doc.MailMergeSettings;
settings.MainDocumentType = MailMergeMainDocumentType.MailingLabels;
settings.CheckErrors = MailMergeCheckErrors.Simulate;
settings.DataType = MailMergeDataType.Native;
settings.DataSource = dataSrcFilename;
settings.Query = "SELECT * FROM " + doc.MailMergeSettings.DataSource;
settings.LinkToQuery = true;
settings.ViewMergedData = true;

Assert.AreEqual(MailMergeDestination.Default, settings.Destination);
Assert.False(settings.DoNotSupressBlankLines);

Odso odso = settings.Odso;
odso.DataSource = dataSrcFilename;
odso.DataSourceType = OdsoDataSourceType.Text;
odso.ColumnDelimiter = '|';
odso.FirstRowContainsColumnNames = true;

Assert.AreNotSame(odso, odso.Clone());
Assert.AreNotSame(settings, settings.Clone());

// Opening this document in Microsoft Word will execute the mail merge before displaying the contents. 
doc.Save(ArtifactsDir + "MailMerge.MailMergeSettings.docx");
