Dear Friends,
We have an application which is developed using VC++ 2008. This application will refer the database with in the intranet network. Now I want to access this database from different network(via internet). For example, similar to "Form" getting user details and store it in the server and retrieve data back.
Kindly anyone suggest or guide me.
Thanks and Regards,
S.Shanmuga Raja

Assuming the server holding your database is accessible across the internet it would be just the same.

I want to access database from different network.. like web application.

Repeating the same vague question is not helping your cause. What exact technical problem are you facing? Connecting from one system to another through a network, whether intra or inter is exactly the same. All you need to ensure is that each system can connect to the other through subnets and firewalls.

My Database in India n my user access database from some other country. Plz tell me, for this scenario what connective needed to access the database.

I already told you. And since you have given no information, other than a vague "I want to" it is impossible to offer any further suggestion.

Right now Application connected with database using OLEDB(connective). User are using this application within the same network(same building). Now they want to access the database from different place(not in the same network and different country). My question is same connective(OLEDB) procedure helpful for this scenario?

And he has a CodeProject article on sockets.

And he is asking how to conect two machines on an IP network!

WTF? You got to be kidding!

First I am getting doubt whether you are engineers??? you don't know to behave in general forum.. If you are not interest to answer to my question then nothing Problem.. Thanks for your comments.. Richard MacCutchan, ThePhantomUpvoter, Erudite_Eric I am sure this engineers spoil and pull down the code project respect and dignity.
Dear Friends (Richard MacCutchan, ThePhantomUpvoter, Erudite_Eric) please go through "
HOW TO ANSWER A QUESTION" by Mr.Chris Maunder
I hope code project take necessary action against them..

You just answered the question yourself. You create a web-server-application (ASP.NET / PHP / CGI / Java etc.) on the same network as the database. Now the web-client-application can access the database through the web-server-application over the internet.

Don't do that.
It would require exposing the database to the internet. Although it is possible to expose a database safely to the internet is VERY unlikely that you will succeed at doing it safely.
Instead you write an application which talks to the database. Then your 'clients' talk to the application. This doesn't insure that it will be safe but by limiting functionality you at least narrow the attack venues and with care it can be made safe.

Hello,
I came across something i don't understand one little bit, and i hope you can help me understand it.
The code is in the function OnDraw with parameter CDC* pDC and i have the following code
rectPreviewClient.SetRect(0, 0, pDC->GetDeviceCaps(HORZRES), pDC->GetDeviceCaps(VERTRES));
...
CDC dc;
dc.Attach(pDC->GetSafeHdc());
And the CRect rectPreviewClientis given to a function which draws some stuff.
The map mode isn't changed and it remains MM_ANISOTROPIC even until the drawing of the elements.
The thing i don't understand is how come i can print stuff for example
dc.TextOut(0, rectPreviewClient.bottom - tm.tmHeight,....)
when its clear the both CDC members have different dimensions.
The dpi's are different pDC have 600 dpi and dc has 96.
If i use GetDeviceCaps(HORZRES) and GetDeviceCaps(VERTRES)on dc i get smaller numbers and yet i can print stuff with a lot higher coordinates.
Note: The dc is used for PrintPreview. Currently i am trying to change the font size and i need to change the map mode to MM_TEXT but when i call TextOut with the coordinates normally used the text is drown outside the CDC. If the MM_TEXT is removed the text is shown but too small
Edit: I fixed the Font size without changing the map mode with CreatePointFont and height of the Font size but the question remains How can i use coordinates from one CDC to another with different dpi and dimensions.
Any help will be appreciated. Thank you in advance.

In a running process say “ProcessOne “
Loaded a module say “DllOne.dll” and calls its exported function say “DllOnesFunction1”
In “DllOnesFunction1” Calls Loadlibray and dynamically loads another module say “DllTwo.dll” and calls it function say “DllTwosFunction2”
In “DllTwosFunction2” Calls Loadlibray and dynamically loads another module say “DllThree.dll” and calls it function say “DllTthreesFunction3”
if so how I can Hook “DllTthreesFunction3” with “MyDllTthreesFunction3”
First whether it is possible ? is start from IAT of “ProcessOne “ Then what ? is EAT of “DllTwo.dll” ...
If possible please give me what way I may start to find answer or just give brief idea or link to learn about it
Expecting a valuable reply, Thanks in advance,
Regards,
Dileep S

A module function may be imported by many other modules. I've used 2 different approaches:
1. I hooked the import table of all modules that imported the function of my interest.
2. If there were too many modules that imported the function then I did the following: I've hooked the function of my interest by writing a jump into the first few bytes of the function that jumps to my code. Of course before the hook code jumps back to the original function it must execute the instructions that have been overwritten by teh jump, depending on the first few instructions you may have to copy more than a few bytes.
Advantages of #1: You don't have to mess around with the instructions of the hooked function like you have to with #2.
Disadvantages of #1: You have to find and hook the import table of all modules that import the specified function.
A possible mistake in both cases: The program may unload/reload hooked DLLs and in this case you have to be aware of this and you have to repatch after reload.
Almost forgot to mention: approach #1 is often called "API redirection". You can find good stuff by googling this.
And another thing I forgot: if it wouldn't be obvious this task is easiest to perform by injecting your own DLL with the hook code into the guest process. Work inside the hookable process and not from outside.

Is it possible by hooking GetProcAddress() function?
Hook GetProcAddress with my myGetProcAddress(). Now myGetProcAddress will be notified on calling GetProcAddress. You can return the address of MyDllThreeFunction on receiving a getprocaddress() for DllThreeFunction.
