    @Dante-Pham You want to combine multiple docx files into one? It is not possible with Qt. It will for sure not work if you just append them, even not in binary mode. You either need a library which understands docx format or you need to write docx parser by yourself.

    @jsulm Do you know any other platform like Qt that can read and write multiple docx files like what i mentioned ?

      @Dante-Pham No I don't. Maybe Microsoft provides something? It is their format. And you can take a look at LibreOffice - it can read/write docx.

        docx is a zip file so you can understand how your method cannot possibly work.
        There is currently no free library in C++ that lets you handle it (a few commercial ones claim to be able to but I never tested them).
        The LibreOffice/OpenOffice code to handle MS office files is too linked to the application to be used easily.
        There's a .Net library that lets you handle them: https://github.com/WordDocX/DocX so you can use it with C++/CLI if you are ok being tied to .Net

          @VRonin Would you mind telling me exactly how to use this ? I'm not very familiar with .NET.

            Hi. Even with DocX you will need to understand the actual structure of the document and
            merge it by hand adding text to the target doc.
            There is no tool i have ever seen that can BINARY merge word docs. (only in very old times)
            Also note that DocX only goes to word 2007. Not newer. ( or docs not updated)
            But DocX seems very high level.

            I have never used .NET from c++. Im sure its pretty easy in Visual Studio but cant confirm.

            Can I ask why you want to merge them ?
            Also is it a requirement that your app can do it when no Office installed?

              @mrjj Basically I'm trying to make a program that can copy lots of small documents and put it into just one file. It's like you have multiple questions and you merge them into just one test.
              Office should always be installed with this program ( except for when it has already been installed )

                Ok. i see.
                Would it be option to do it via pdf or must end result be a doc?

                I did something the same with
                https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
                (the free command line version)
                so made small VBA macro that printed/saved the docs to pdf and then just
                ran tool on it. and got perfect pdf from it.

                  @mrjj Input and Output should be .doc or .docx so that it will be easier for users to modify the files. Changing .doc to .pdf and vice versa is good but doesn't help very much because the core features I intend to implement will, in most cases, involve in working with .doc and .docx

                    Ok. well DocX or something like it seems the way to go then.

                    There is also the option of a pure VBA project. But the widgets you
                    get there is not as advanced as Qt versions but the merging of docs would
                    be easy.

                      @mrjj After doing some research I think DocX may just work. However, I have never had any exprience dealing with .dll files, let alone using it in Qt. Do you have any suggestions on how to use it ?

                        Hallo, I think to understand the binary docx structrue is a very hard stuff.
                        Much more easy it would be to use the AcxtiveX interface for word.
                        Code something like this:

                        Open Doc1, select all text, copy to clipboard, close Doc1
                        open Doc2, set cursor to the end of the document, paste text, save doc2.

                        The AciteveX interface of Qt is very good and I have much experiences with it. I use it for Excel (fill Tables) and for Access (open Report an export to PDF.

                        You can hide the office windows by this task, so that the user sees nothing of you tasks.

                          @Dante-Pham
                          Hi.
                          Using a DLL involves loading it and resolve symbols.
                          Meaning to be able to run functions from it.
                          You also need a .h file. (didnt see any?)
                          You should also get a copy of visual studio as .NET is best/easy/to used from that IDE.
                          Then you shall google calling a .net DLL from C++ as there might be other things to look out for.

                          Maybe @VRonin knows a easier way to use the .DLL in Qt.

                          Update:
                          Its available via Nuget
                          so it should be easy to install and try the samples directly in VS.
                          Then try to mix with Qt.

                          Update 2:
                          Using VBA, this short code can merge all docs from a folder.

                          Sub MergeDocs()
                              Dim rng As Range
                              Dim MainDoc As Document
                              Dim strFile As String, strFolder As String
                              Dim Count As Long
                              With Application.FileDialog(msoFileDialogFolderPicker)
                                  .Title = "Pick folder"
                                  .AllowMultiSelect = False
                                  If .Show Then
                                      strFolder = .SelectedItems(1) & Application.PathSeparator
                                  Else
                                      Exit Sub
                                  End If
                              End With
                              Set MainDoc = Documents.Add
                              strFile = Dir$(strFolder & "*.docx") ' can change to .doc
                              Count = 0
                              Do Until strFile = ""
                                  Count = Count + 1
                                  Set rng = MainDoc.Range
                                  With rng
                                      .Collapse 0
                                      If Count > 1 Then
                                          .InsertBreak 2
                                          .End = MainDoc.Range.End
                                          .Collapse 0

                            For what you need to do I'd point you to http://stackoverflow.com/questions/18351829/merge-multiple-word-documents-into-one-open-xml/18352219#18352219

                            Using .Net dlls in visual studio is extremely easy, just open the project property and add a reference to the .dll, then right click on the .cpp file you need to use the library in, go into properties and activate /clr in the "Common Language RunTime Support" field under general. Now you can use C++/CLI in it which is quite close to C#

                              @Andy314 I am using ActiveX but i have no idea what functions are used to do what you describe. Would you mind giving me some examples ? How do I copy and paste ? How to hide the window ?

                                Maybe @VRonin knows a easier way to use the .DLL in Qt.

                                Update:
                                Its available via Nuget
                                so it should be easy to install and try the samples directly in VS.
                                Then try to mix with Qt.

                                Update 2:
                                Using VBA, this short code can merge all docs from a folder.

                                Sub MergeDocs()
                                    Dim rng As Range
                                    Dim MainDoc As Document
                                    Dim strFile As String, strFolder As String
                                    Dim Count As Long
                                    With Application.FileDialog(msoFileDialogFolderPicker)
                                        .Title = "Pick folder"
                                        .AllowMultiSelect = False
                                        If .Show Then
                                            strFolder = .SelectedItems(1) & Application.PathSeparator
                                        Else
                                            Exit Sub
                                        End If
                                    End With
                                    Set MainDoc = Documents.Add

                                        Set rng = MainDoc.Range
                                        With rng
                                            .Collapse 0

                                _ DocX only has a .DLL file and a documentation (.chm file) which is very unfinished. Lots of explainations in there are missing. After a while I found myself lost and my code messed up. I tried emailing the guy and he hasn't replied to me yet. Still, I did try adding library into Qt but it only takes .lib files. I found a documentation which show me how to add .dll files but it still didn't work after numerous tries
                                _ I don't think Nuget and VBA are going to work for me because I don't know anything about them, which makes it difficult for me to modify and make tweaks to them ( which i am definitely going to ). Still, I have to do more research on them. I will be back very soon

                                  @Dante-Pham said in How to read and write docx files in Qt:

                                  Nuget

                                  That is just a system to easy get a lib for Visual Studio.
                                  Click and Play , so to speak :)

                                    Ok so thanks to @VRonin , I found this https://youtu.be/qOfiiYP2JTI?t=2m11s , in which is pretty much what I'm looking for ! The only problem is I don't know C# . Is there any way we can do that in Qt in C++ ??

                                      Well if you know c++ then C# is pretty easy.
                                      https://msdn.microsoft.com/en-us/library/yyaad03b(v=vs.90).aspx

                                      I think you can do it almost same way with Visual Studio and c++ but of course the syntax will be
                                      different.
