embedding object (jepg, png and pdf etc) in word document by openXML.

≪ Previous: transitional or strict format ?

Hi All,

In Open XML, there are basically 2 different classes provided to embed any file or object in Open XML Document.
1. EmbeddedPackagePart
2. EmbeddedObjectPart
EmbeddedPackagePart is used to embed Open XML Packages inside document, for e.g. docx, xlsx files.
Using EmbeddedObjectPart, we can add any file as an Object inside document.

Scenarios:

Embed Open XML package inside document

In this case, we can use EmbeddedPackagePart class and use feeddata method of same class, which will create a package file (extension: .package). And store it into embeddings folder under document folder of Open XML package.

As package is an Open XML package, OpenXML SDK easily can cache it and store it inside document package.

MSDN Code Ref. https://msdn.microsoft.com/en-us/library/ee355229(v=office.12).aspx

Embed Object inside document

In this case, we use EmbeddedObjectPart with application/vnd.openxmlformats-officedocument.oleObject content type. When we use feeddata method of this class, it will create a Bin file (extension: .bin) and store it in embeddings folder.

Now issue is Open XML itself not able to create bin cache file. It’s not get linked with Object tag in document, as Microsoft Office does not recognized bin file created by Open XML SDK.

So we use Open XML Productivity Tool shipped with Open XML SDK from MSDN ( https://www.microsoft.com/en-us/download/details.aspx?id=30425 ). And use that tool to regenerate code of Docx file, which have an embedded Object using Microsoft word.

In code we have found, a Base 64 String, which is used to generate object. When we convert that Base 64 String to check file type, we have found that file signature (Magic Number: https://en.wikipedia.org/wiki/Magic_number_(programming) ) of Base 64 was related to Old file extensions e.g. Doc, xls.

List of file signatures : https://en.wikipedia.org/wiki/List_of_file_signatures

Can someone help me on this?

space inside Internal hyperlink fieldcode text

January 11, 2017, 9:12 am

≫ Next: Write with position

≪ Previous: embedding object (jepg, png and pdf etc) in word document by openXML.

Hello,

We have a application where we have to count the length of the fieldcode text in word document for which we are counting the text inside the InstrText tag which is working fine so far. But we are not able to calculate the fieldcode text of the internal hyperlink field. we using below code snippet to manually build instrText of the hyperlink field.

string HyperlinkFC = string.Empty;
if (element.Attributes().Any(a => a.Name.LocalName == “anchor”))
{
string s = @”HYPERLINK \l”;
HyperlinkFC = string.Format(” {0} \”{1}\” “, s, element.Attribute(W.anchor).Value);
}
fieldCodeText.Append(HyperlinkFC);

Above code is working fine for some cases like below:
{HYPERLINK \l “_Toc165886552”}

But it is failing for some cases where there is a trailing and leading white space inside the curly braces of Hyperlink fieldcode in the begining and end as below

{ HYPERLINK \l “_Toc165886552” }

It is giving 2 characters length difference than expected.

Any help will be truly appreiciated!!

Thanks

Hello,

I'm new to Open XML.

I'm trying to create an Excel file using a text input file.

I'm just trying to Bold the top row, but I don't seem to be having any success using a stylesheet.

Using VB.NET

My Stylesheet contains 2 fonts.

The first, size is 13, font is bold.

The 2nd, size is 13, font is not bold.

If I'm in the first row, I want to use the first font, any other rows I want to use the 2nd font.

The data gets written to the spreadsheet but it will only use the first font definition.

≪ Previous: Slow process

The Open XML SDK 2.5 Productivity Tool does some amazing things for me, but it would be even better if there could be some way to automatically fill in the Browse Files to Compare dialog box, such as with the last files opened. I could probably add this highly useful feature if somebody knows where the source code is.

What I tried:

Google search for: Open XML SDK Productivity Tool command line
I used the Spy++ program that comes with Visual Studio. It only recognizes the dialog box, not the dialog box controls.
I wrote a program to find the dialog using EnumWindows(). I can find the dialog and move the control focus by sending it tab characters, but EnumChildWindows() doesn't find the dialog controls, and sending keystrokes to the dialog doesn't fill in the dialog controls.

Hello together,

I have a rather tricky problem. I need to find the enumeration symbol in front of a paragraph, like

1) This is the first line

2) this is the second line

In this case the 1) and 2) is not contained within the paragraph itself, but hidden somewhere else.

Is there any way to get this information?

Kind regards,

So I'm trying to open a word document and replace a block of text in the bottom right side of the first page with a picture. I am able to replace the image, but it is not positioned the way I want it to be. Changing the frame properties/paragraph properties doesn't seem to help. Is there another approach that I seem to be missing?

if (text.Text == "text match")
{
paragraph.RemoveAllChildren();
ParagraphProperties paraProp = new ParagraphProperties

KeepNext = new KeepNext(),
FrameProperties = new FrameProperties
{
HeightType = HeightRuleValues.Auto,

XAlign = HorizontalAlignmentValues.Right,
YAlign = VerticalAlignmentValues.Bottom
}
};
paragraph.ParagraphProperties = paraProp;
paragraph.Append(new Run(element.CloneNode(true)));
break;
}

Edit: I forgot to mention, this block is running in a large nested foreach loop iterating through every text in every run in every paragraph. In this context, paragraph is the current paragraph.

Starting with 2.8, the nuget package forces the install of a bunch of packages from (and including) Core. I understand and support the fact that Core is supported.

Hi, I have a project where i need to add plain text as well as the content of small .docx files to a main .docx.
I have created a test case, and with the use of AlternativeFormatImportParti I can successfully perform the following code to add plain text in my files.

string chunkId = "D"+Regex.Replace(DateTime.Now.ToString(), @"[^\d]", "");

AlternativeFormatImportPart chunk = _mainDocPart.AddAlternativeFormatImportPart(
AlternativeFormatImportPartType.TextPlain, chunkId);

	chunk.FeedData(memstream);

AltChunk altChunk = new AltChunk();
altChunk.Id = chunkId;

parent.InsertBefore(altChunk, placeHolder);

It seems like when i do this the saved file cannot be opened by Word (Corrupt file)

I can add paragraphs and other stuff, but not AltChunck when I initiate the WordprocessingDocument as follows

var byteArrayWithFileFrom360 = ProcessFileHandler.GetFileContent(204735);
