I keep pointing you to MSDN and various related pieces of documentation, but you keep coming back here asking for the same thing. Try using the tools at your disposal (Google, Bing etc) to find what you are looking for.
One of these days I'm going to think of a really clever signature.
I have asked a lot about how to read PDF files(just like JAWS, a quit good screen reader), what I want to ask is that does anybody know how JAWS make it. I mean,what kind of tech does JAWS take advantage of. I guess it used MSAA.
I'm trying to do the same thing with JAWS now, so I need your help, if anybody has done such things, please help! Appriciate it.
I made a .NET COM DLL (VS2012, C#) it registers fine with regasm, but not with regsvr32. Also when I add the .tlb into installer and extract the com stuff (Installshield 2012) there is no registry entries after I have ran the installer. DLL is 32-bit and I'm using 64-bit Windows.
I am using office 2007 interop DLL to create an Excel sheet in c#.NET.
when I tried to test my app on a machine with office 2003 installed I get an exception because of the version number of the DLL . How can I determine in runtime what version of office is installed and then load the appropriate interop DLL for that version ?
If you do not need features which became available in Office 2007, just use an interop dll for old versions of Office also when current Office is installed! A PIA created with Office XP still works with Office 2010.
Otherwise, you have to find out the registry keys of Excel...
