    @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.

                        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$(strFolder & "*.docx") ' can change to .doc
                            Count = 0
                            Do Until strFile = ""
                                Count = Count + 1
                                Set rng = MainDoc.Range
                                With rng
                                    .Collapse 0
                                    If Count > 1 Then
                                        .InsertBreak 2
                                        .End = MainDoc.Range.End
                                        .Collapse 0
                                    End If
                                    .InsertFile strFolder & strFile
                                End With
                                strFile = Dir$()
                            Loop
                            MsgBox ("Files are merged")

                          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#

                              _ 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

                                Nuget

                                That is just a system to easy get a lib for Visual Studio.

                                  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.

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

                                          As mentioned above you'll need to use a dialec of C++ called C++/CLI.
                                          You can download visual studio from https://www.visualstudio.com/vs/community/ you can find a crash course in the dialect here: https://www.codeproject.com/articles/19354/quick-c-cli-learn-c-cli-in-less-than-minutes
                                          Given the name googling it is a nightmare you are better off just googling stuff in C# and either translate it (it's not that hard) or if you go on msdn the examples are often available in C#, VB.Net and more importantly C++/CLI (see for example https://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient(v=vs.110).aspx?cs-save-lang=1&cs-lang=cpp)

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

                                          DocX only has a .DLL file and a documentation

                                          That's all you need, you use #using <DocX.dll> to include it in the source file (that needs to be compiled with the /clr option )

                                          Here you can find a small example of a qmake project using this paradigm

                                          "La mort n'est rien, mais vivre vaincu et sans gloire, c'est mourir tous les jours"
                                          ~Napoleon Bonaparte
