I have an application, programmed in vb6 that needs some dll-files and ocx-files installed in windows 7.

I already have an installer created with innosetup that includes all needed files and also installs the mysql Connector-ODBC for Windows (x86, 64-bit)

If I just put all files into one folder the installation doesent work, I get the error

Component MSDATGRD.OCX or one of its dependencies not correctly registered: a file is missing or invalid

I tried a search for msdatgrd.ocx portableapp but no Idea

Is there an easy workaround to make this app running without installation?

You can download the files I want to pack into a PortableApp here.

I tried opening the Setup.exe with dependency walker, but unfortunately I have not enough expertise to use that tool. here a screenshot

Although the output of dependency walker seems to be deceptive, see here:

Win 7, 64 bit, dll problems

anyway: I downloaded those 9 files here and packed them , now it shows even more other files missing: pastebin.com/8LawEbuk 7 this doesent seem to lead anywhere cause the dependency walker is too old

I am looking for something really simple to create, no matter the filesize in the end, as I am not a windows programmer

  • Here is another [example without myodbc](http://www31.zippyshare.com/v/21311637/file.html) It also complains about MSDATGRD.OCX, it just creates a grid without mysql: http://i.stack.imgur.com/Hdp4v.png – rubo77 Aug 19 '13 at 08:12

The error below:

Component MSDATGRD.OCX or one of its dependencies not correctly registered: a file is missing or invalid

is probably because you haven't registered the ocx component. If you are manually distributing this component, then you also need to register it in the user's machine. To do so you issue the following command:

regsvr32 msdatgrd.ocx from the command line (note that you need to have admin rights).

If you don' want to install the application in a typical application directory (i.e.: C:\Program Files) you can use the %APPDATA% or %LOCALAPPDATA% variables to get Romaming (if on a network) and Local user's application directory, respectively. You can also use Windows API to do that. For example: 

if (SUCCEEDED(SHGetFolderPath(NULL, CSIDL_COMMON_APPDATA, NULL, 0, szPathName)))
{
    PathAppend(szPathNam, _L"\\YourCompany\\YourProduct\\") );
}

Besides the .ocx (which is a Dll that implements specific interfaces), you should note that if you use other methods from a DLL you wrote inside your setup.exe then you have to export them. Nice articles below:

c++ exporting and using dll function

EDIT:

I found this:

Use OCX without registering it

Be aware the Windows XP will be descontinued in April 2014!! Also note that doing this is a dirty hack and should be avoided. I don't know what happens on Windows 7 and Windows 8 (honestly you shouldn't spend time with tricks, but changing to a portable dll component)

Also I heard about http://boxedapp.com/ I've never used but it worth a look.

  • it could be, that's why I explained about getting local user's path. But to register the ocx you must have at least Power User privilege. – jyz Aug 19 '13 at 12:05
  • isn't there a way to include it all in one directory without registering?? It wouldnt matter if that functions would already be available in systemwide files. I think thats what a PortableApp should run like. – rubo77 Aug 19 '13 at 12:08
  • It could also be a somehow virtual surrounding, where i will just run that one program. (I am looking for something really simple to create, as I am not a windows programmer) – rubo77 Aug 19 '13 at 12:10
  • Why do you need an ocx? Can't it be just a simple dll? OCX is the top-most Windows stuff. Why don't you build a simple dll (without implementing the COM CoClasses) that do whatever you need? Then you can put it at the same directory as you want. – jyz Aug 19 '13 at 12:15
  • can you somehow convert an OCX into DLL? Without gnoing the code? – rubo77 Aug 19 '13 at 12:30
  • Without changing code? I don't think so... The easiest way is create a new C++ DLL Project Wizard and copy the code from the ocx project into he new dll one. Then you can use `LoadLibrary()` and `GetProcAdress()` Windows API functions to get the exported symbols from the dll. – jyz Aug 19 '13 at 13:53

You can use the Visual Basic Package and Deployment Wizard (PDW) to create an Standard Setup Package for your program, then check what appear in the dependency list. The package would require Admin rights to install.

To use the OCX without admin rights, you need to check if you can activate the ActiveX via Registration-Free COM. You can generate the manifest via mt.exe from Windows SDK, but Make My Manifest has better support for a VB6 project. You need to isolate not only the grid control but whatever COM object required by the control.

MSDATGRD.OCX requires these files: msstdfmt.dll and Msbind.dll.
