On Windows, the entry point to programs is frequently called WinMain.

In an MFC Application, the entry point is CWinApp::InitInstance() - the WinMain entry point is in the MFC libraries.

There are lots of files with lots of different names. I guess the main
file is called q_main.c

But still can not find any WinMain() or other main() method in the file.
Any ideas?

We are using the cad library for developing the Auto cad application.We are in need to read the Dxf file using your library.Just explain how to read the dxf file.

Never let anything go for granted. <>

File Properties ->Summary

Does anyone now about MFC/Win32 API to get and set the File Properties in the summary tab like, Subject, Title, Category etc.

The closest I was able to get was DSOFile library(dll) provided by Microsoft but I don't want to use a third part library (which I will have to ship along with my binaries).

Any API valid for Windows NT/2000 to get File->Proprties-.Summary will be highly beneficial.

Thanks and Regards,
Amol

Thanks a lot Mike for the help.

I was successfully able to get summary and custom information out of this.
But I have one problem with this regards. The file (format) whose File->Properties I want to extract has something called "Configurations" in addition to "General", "Summary", and "Custom" tabs in it's File properties.
This TAB is exactly the same as "Custom" tab in File->Properties. The help documentation of my file-format mentions that these properties are written to the file in an 'OLE Property' way. But the source code you provided doesnot mentions any way to get the "user-defined" tab information.

Can you please help me out in extracting such information of a file.

Best wishes and Regards,
Amol

When you declare the function, wrap it in an extern "C":

<br />
extern "C" {<br />
extern void the_c_function() ; <br />
}<br />

This should be in library or in my class if so i don't have c library source code
then how can modify it
thax..

Wrap the header file:

<br />
extern "C" {<br />
#include "api.h"<br />
}<br />

Or just duplicate the declarations you want.

If you're writing a C library, it's good form to put the extern "C" *inside* the header file but not every one does it.

Database Problem

Hi there,

I have a problem with the MS Access ODBC driver.

My code looks something like this
First, i open the database using the Acces driver
CDatabase database;
CString SqlString;
CString sDriver = "MICROSOFT ACCESS DRIVER (*.mdb)";
CString sDsn;
CString sFile = "d:\\MyDB\\MyDB.mdb";
sDsn.Format("ODBC;DRIVER={%s};DSN='';DBQ=%s",sDriver,sFile);
database.Open(NULL,false,false,sDsn);

Then I create the recordset (the class MyRS is derived from CRecordset)

MyRS rs (&database);
SqlString = "SELECT * From Table1";

What works:
rs.Open(CRecordset::forwardOnly, SqlString);
THis however does not allow using MoveFirst, MoveNext and so on nor to edit and updata records.

These two do not work. I get told that the driver does not support dynamic or dynaset pointers.
rs.Open( CRecordset::dynaset, SqlString, CRecordset::none );
rs.Open( CRecordset::dynamic, SqlString, CRecordset::none );

This works, and I can edit and move back and forward in the recordset, but i cannot filter the recordset with an Sql statement:
rs.Open( CRecordset::snapshot);

does not work : rs.Open( CRecordset::snapshot, SqlStatement);

I did not find in the MSDN that the driver i use does not support dynasets.

Thanks a lot

rs.Open( CRecordset::dynamic, SqlString, CRecordset::none );

is there any way to determine a window has standard scrollbar or scrollbar control? in other word, how to scroll a window that does not belong to my app?

sure, you are right
but i want to get some information about the scrollbar(range,pos etc.)
Do you know how can i do it???

thanks

Why don't you use GetScrollRange with the HWND of scroll bar
MSDN says
If the specified window does not have standard scroll bars or is not a scroll bar control, the GetScrollRange function copies zero to the lpMinPos and lpMaxPos parameters.

this might help Smile | :)
