Insert Image on the header in the word doc

dineshbali · April 14, 2008, 10:59am

Hi alexey.noskov,

This is Dinesh, We were discussing about replacing Image on the header on the word doc using Aspose.

But for some reason chat was disconnected.

I tried your code but then you find that I am using older verison of Aspose,
I have downlaoded the latest version and it is now giving me errors at many places in the application

Mainly I have below 2 errors, I am also pasting my old code on which I am getting the errors

I am also attaching the chat which we had

Many thanks for your co-operation

My email is dinesh@bizzybit.co.uk

The type or namespace name ‘Word’ could not be found (are you missing a using directive or an assembly reference?)
The type or namespace name ‘app’ could not be found (are you missing a using directive or an assembly reference?)

‘Aspose.Words.SaveFormat’ does not contain a definition for ‘FormatDocument’

// COde which was running with older version.
private Document OpenDoc()
{
    Word app = new Words(); 
    return app.Open(Server.MapPath("Templates_Office/dispatchnote.doc"));
}

Document doc;
doc = CreateInvoiceFromDataSet();
doc.Save(
"DispatchNote.doc",
SaveFormat.FormatDocument, // Is it fine If here I write "SaveFormat.Doc" 
SaveType.OpenInBrowser, Response);
Response.End();

Awaiting your reply

Hi

Sorry, internet connection was lost on my side. There are some differences in API.

The breaking changes in Aspose.Words for .NET 5.x.x are:

All collection classes, such as Paragraphs, Runs, Tables, Bookmarks etc have been renamed into ParagraphCollection, RunCollection, TableCollection, BookmarkCollection, CellCollection accordingly.
New namespaces Aspose.Words.Fields, Aspose.Words.Lists, Aspose.Words.Markup, Aspose.Words.Properties and Aspose.Words.Tables were introduced and classes moved into the new namespaces.

Please try using the following code instead yours.

private Aspose.Words.Document OpenDoc()
{
    Aspose.Words.Document doc = new Aspose.Words.Document(Server.MapPath("Templates_Office/dispatchnote.doc"));
    return doc;
}

Document doc;
doc = CreateInvoiceFromDataSet();
doc.Save("DispatchNote.doc",
    Aspose.Words.SaveFormat.Doc, // Is it fine If here I write "SaveFormat.Doc" 
    Aspose.Words.SaveType.OpenInBrowser, Response);
    Response.End();

Best regards.

Hi Alexey Noskov,

Many thanks for your great help.

But I am still getting the same error

The type or namespace name ‘Shape’ could not be found (are you missing a using directive or an assembly reference?)

AT LINE

(shapes[0] as Shape).ImageData.SetImage(HttpContext.Current.Server.MapPath("") + “\Images\assets\logo_nucleus.gif”);

In below code:

Document doc = OpenDoc(strTemplate); doc.MailMerge.ExecuteWithRegions(dataSet); 
HeaderFooter myHeader = doc.FirstSection.HeadersFooters[HeaderFooterType.HeaderPrimary]; 
NodeCollection shapes = myHeader.GetChildNodes(NodeType.Shape, true);

(shapes[0] as Shape).ImageData.SetImage(HttpContext.Current.Server.MapPath("") + "\\Images\\assets\\logo_nucleus.gif"); 

doc.Save(HttpContext.Current.Server.MapPath("") + "\\pdf\\Supplier\\TestDoc.doc");

Now what is the problem

Regards
Dinesh

Hi

Thanks for your request. Please try adding Aspose.Words.Drawing namespace or using Aspose.Words.Drawing.Shape.

Best regards.

Hi,

Many thanks for your quick reply.

I am now getting error

System.Web.HttpUnhandledException: Exception of type System.Web.HttpUnhandledException was thrown. —> System.NullReferenceException: Object reference not set to an instance of an object.

at line

NodeCollection shapes = myHeader.GetChildNodes(NodeType.Shape, true);

because

HeaderFooter myHeader = doc.FirstSection.HeadersFooters[HeaderFooterType.HeaderPrimary]; 

myHeader is comming null.

HeaderFooter myHeader = doc.FirstSection.HeadersFooters[HeaderFooterType.HeaderPrimary]; 
NodeCollection shapes = myHeader.GetChildNodes(NodeType.Shape, true);

Why header is null when my doc has the header in it?

Thanks again

alexey.noskov · April 15, 2008, 4:34am

Hi

There are three types of header in word document: HeaderPrimary, HeaderFirst and HeaderEven. Maybe your document doesn’t contains primary header.

Try using

HeaderFooter myHeader = doc.FirstSection.HeadersFooters[HeaderFooterType.HeaderFirst];

Or

HeaderFooter myHeader = doc.FirstSection.HeadersFooters[HeaderFooterType.HeaderEven];

Also please attach your document for testing.

Best regards.

dineshbali · April 15, 2008, 4:52am

Many Thanks for your great help.

It was

HeaderFooter myHeader = doc.FirstSection.HeadersFooters[HeaderFooterType.HeaderFirst];

My problem is solved

Thanks again
