Do you really neeed that (you can also use directly your DLL)?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

A DLL is self registering (ie. by calling its DLLRegisterServer known function, in your case regsvr32.exe call this function) when it is a COM server.

You can use native DLLs from .NET using P/Invoke. Following MSDN article may be of help -

Dear friends,
Can I use any alternate for DSO Framer control to display document, excel, ppt, pdf etc files. I tried aspose too, but it was
not meeting our requirements. Because they want a tool which takes the documents as it is like DSO Framer. In aspose to
change the document format we need to change the code also.
And I need to email this document too. So that document may be changed so frequently. And dont forget that document must have
to be made using .Net frame work library(com component is not preferable). What shoud I use in this case. Please help me.
Thank you.

Hi Sohail,
Thank you for ur valid information. Actually I have made an IE toolbar using
vc++ ATL COM. It cotains Threads, And many things that mfc supports.
For example,
It consists of a Ticker that shows some information from a server. The ticker
is
actually a class inherited from CStatic. And also Threads in VC++ , that
performs various functionalities like, Collecting data from Server. Showing
Advertisements live , from different sites etc. So I think, I cant perform
these things in Mozilla tool bar made from XML. Right na.
Thanks
George

well you can certainly do in Mozilla what you have so far created in IE.
From what you said, I beleive your UI logic and Business logic are clubbed together and created only for IE.
If you seperate out the UI logic of toolbar in your IE and put the business logic in a seperate COM dll which is callable from the UI logic then you can invoke the same business logic from within Mozilla toolbar. The UI logic of toolbar is written in XML but there is a way to call COM interface methods. Mozilla also has something called XPCom - COM variant.
I hope this helps

you want to use that COM dll .. right ?
then you have to register that COM dll in to your system.
To do that pres 'Start' button take 'Run' Applicaiotn, inside Run win type 'Regsvr32' then space your COM dll file location.
for example., you COM file location is C:\\app.dll then
in Run window, type 'regsvr32 c:\\app.dll' press enter
now your COM dll is register wit your system.
then write COM client program using api's like CoInitialize(NULL),CoCreateInsatnce() and CoUninitialize();
This is the way you have to use COM dll.
bye.

Hi Sakthiu,
That's fine, i have registered successfully but, i didn't know how to used to the client application. i didn't find good and cleared articles.
some articles tells that
AfxOleInit() - COM Initialize.
AfxOleTerm() - COM Uninitialize.
i have really confused. please send any cleared article URL or any sample code...
Thankx...

Hi Prasad,
I had read ur article.It's really usefull for me...
I followed correctly through ur sending article and successfully loading my dll,
but when i clicked the OK button,
1) MessageBox within "s" message and
2) MessageBox within "Failed" message showned and
3) assertion failed would be throwned.
my source code look like this...
void Ctest2_vcDlg::OnBnClickedOk()
{
// TODO: Add your control notification handler code here
CString s1,s2,s3;
s1=_T("c:\\p1.pdf");
s2=_T("c:\\pppp.jpg");
s3=_T("jpeg");
BSTR b1,b2,b3;
b1=s1.AllocSysString();
b2=s2.AllocSysString();
b3=s3.AllocSysString();
typedef HRESULT (WINAPI *pMakeFile) (BSTR,BSTR,BSTR);
pMakeFile MakeFile;
HMODULE hDll=LoadLibrary(_T("comgs.dll"));
if(hDll)
{
AfxMessageBox(_T("S"));
MakeFile = (pMakeFile)GetProcAddress(hDll,"MakeFile");
if(!MakeFile)
{
AfxMessageBox(_T("Failed"));
}
ATLASSERT(MakeFile);
MakeFile(b1,b2,b3);
FreeLibrary(hDll);
}
else
{
AfxMessageBox(_T("DLL Err"));
ATLASSERT(0);
}
OnOk()
}

No , you haven't.
You are mixing simple dll with COM dll.
In case of COM dll, there would interface(s) present. Which you need to use. This interface in your case is Igscript .
You haven't noticed how interface need to be used from C++ client. Look in to CMfcclientDlg::OnOk.
You need to use CoCreateInstance for this purpose.
Refer CMfcclientDlg::OnOk. from article and post back, if got any issue.

Could not load type StmtGeneratorNET.StatementGeneratorClass from assembly StmtGeneratorNet
