There's no rule that states an application needs to make a registry entry when it is installed.
There may be a way, maybe not - this is vendor-specific.

Hi,
if there is a registry entry you can find it, if there is a Start-Menu entry you can use it too. If not... you have problems  But there is still ways to know it, the problem is they are difficult

Hi,
I want to use a common Database for my Application installed on different Systems in Network. I am using ODBC Connection for Database access through my Application ( application developed in VC++ ).
What should I do for this? ( What is my applicaiton is developed in C# 2005? )

If the database ODBC driver supports network connections then you should be able to adjust
your connection strings to connect to the database over a network.

I am currently working in a office as network supervisor. In office, we are sharing one internet connection. In the meantime, out internet is very much slow due to some virus/Trojan attacked some of our computers.
For monitoring the our computers, I want to make a program in VB6. I need help for making a DLL (activeX if possible) for following task.
-- can detect network card(s).
-- can detect internet request on Main Computer (from which, internet is shared)
-- can show client IP/MAC address.
-- can drop/pass the request.
-- can redirect to another destination in case of porn site.

I think that detecting internet request from other computers to one computer needs NDIS Hook system and this is possible only from C/C++. But I don't know C/C++.

When I try to start my application developed in VC++ .Net 2003 in Vista System,
an error message saying "The application failed to initialize properly (0xc0000142). Click on OK
to terminate the application." is displayed and I cannot run in both mode(administrator/compatibility).
My application need some DLL files in the same folder if DirectX is not installed.
Any help would be greatly appreciated!!

i have a question to ask!
I,m having some trouble with Ftp error code, After i catch error from 'SetCurrentDirectory()' (error code 12031- connection to the server was reset)
I try to display it (using my 'DisplayErrorString' function with below code in):
'FormatMessage (FORMAT_MESSAGE_FROM_SYSTEM,NULL,dwError,<br />
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), <br />
achBuffer, 120, NULL) ;'
but I get nothing, empty string!
Enyone know what to do?
Thanx!

I hope you have got the dwError from the API GetLastError.
You should call the GetLastError function immediately when a function's return value indicates that such a call will return useful data.

Paresh.

Jes I do. I Call GetLastError immediately
if (!theApp.m_pConn->SetCurrentDirectory(voxftpdir))<br />
{<br />
CString str;<br />
err=GetLastError();<br />
...<br />
|

err=GetLastError();
Please change the order. Hope this will serve your purpose.

I think we misunderstand, so I'll recreate my question.
I switched off lan-cable on purposely to see how will my app react!
When I tried to get something from web server I used SetCurentDirectory() which trow error code 12031, but when i tried to get text explaining using:
'FormatMessage (FORMAT_MESSAGE_FROM_SYSTEM,NULL,dwError,MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),achBuffer, 120, NULL) ;'
which puts it in 'achBuffer' i've got nothing!!!!
Afterward i've searched the web and find out that 1203 error code stands for 'connection to the server was reset'.
My problem is how can I get it from a above solution (FormatMessage) and post it with AfxMessageBox???
Thanks!

There's probably no message available in the system. If FormatMessage fails (returns 0) then
call GetLastError()...you'll probably get error code 317 ("The system cannot find message text
for message number ...").
You'll need to supply your own error strings.
