Hi,Support:
Does the API support adding a datetime text element on pdf page and the added datetime text element can auto-update as the OS current date and time?
If so,how to reach it on VB.net?
Thanks for your help.

@ducaisoft,

Can you clarify what you mean by element? Are you referring to a field?

Here is some code example in C#

private void Logic()
{
    var doc = new Document();

    var page = doc.Pages.Add();

    // Create a date field
    DateField dateField = new DateField(page, new Aspose.Pdf.Rectangle(100, 700, 450, 800));
    dateField.PartialName = "dateField1";
    dateField.Value = DateTime.Today;

    // Create a Border
    var border = new Border(dateField);
    border.Width = 5;
    border.Dash = new Dash(1, 1);
    dateField.Border = border;

    dateField.Color = Color.Red;

    // Add field to the document
    doc.Form.Add(dateField, 1);

    // JS cumstom action
    string JS = @"var w = this.getField('" + dateField.PartialName + "'); w.value = new Date();";
    doc.OpenAction = new JavascriptAction(JS);

    doc.Save($"{PartialPath}_output.pdf");
}

Here is a translation to VB(not a VB developer)

Private Sub Logic()
    Dim doc As New Document()

    Dim page As Page = doc.Pages.Add()

    ' Create a date field
    Dim dateField As New DateField(page, New Aspose.Pdf.Rectangle(100, 700, 450, 800))
    dateField.PartialName = "dateField1"
    dateField.Value = DateTime.Today

    ' Create a Border
    Dim border As New Border(dateField)
    border.Width = 5
    border.Dash = New Dash(1, 1)
    dateField.Border = border

    dateField.Color = Color.Red

    ' Add field to the document
    doc.Form.Add(dateField, 1)

    ' JS cumstom action
    Dim JS As String = "var w = this.getField('" & dateField.PartialName & "'); w.value = new Date();"
    doc.OpenAction = New JavascriptAction(JS)

    doc.Save($"{PartialPath}_output.pdf")
End Sub

Yes, The element is a data field that can be auto-updated whiling the document is loaded.
And I want to know whether the data field added by the above codes can be auto-updated to the OS current date and time?

@ducaisoft,

You can add to the current code a custom Javascript action:

I edited the code above. You can modify the javascript to the format you want.

Thanks for your help.
And Else, what version of the API supports DateField feature? I use v21.4, and it does’n support DateField feature, therefore, I did not get the try result.
