For client/server socket programs.
Clients are on local area network (inside the company) and from the internet (outside the company).
Should the Server program uses network IP address or internet IP address or both to accept all clients? why?

No. The IP address that you get through internet is the Proxy's address. Not the client machine (that's inside a lan)'s address. To know more about it, search for NAT- Network Address Translation.
But the client machine can connect to a machine that's outside the lan. The initiat-er makes the difference. If a machine waits outside the lan, (A Server) , you can connect it from a machine inside the lan. But you cannot do the reverse. [My networking data are fading out, so better check it up]

If your IP address is part of a private block (10.0.0.0/8; 172.16.0.0/12; 192.168.0.0/16) then there is no way for an IP address outside that network to connect to your IP address unless your gateway router is set up to do port forwarding or NAT or some other IP aliasing. If your IP address is not within these blocks, then it may or may not be route-able from the internet depending on firewall/gateway settings.

ipconfig displays 3 IP addresses in 3 lines, such as:
//-------------------------------------------
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.101
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.254
//-------------------------------------------
what do the 3 addresses stand for?
which one is Networking IP address?

This is what I called as "Proxy".. you get it? To check it, from your lan, from multiple machines, open IPchicken.com and check the IP adress. it will all be the same. That's what is actually getting exposed to the internet.

A bitwise ANDing of the IP Address and the subnet mask will give you the network address. In this case: 192.168.1.101 AND 255.255.255.0 = 192.168.1.0.

Can anyone tell me how to convert a modeless dialog to a modal dialog?? And vise versa?? Is it possible??
Thanks for any help.
|
|
|
|
|
There's no difference between the code for a modeless dialog or a modal dialog. The difference lies in how the dialog is created. A modal dialog is 'run' by calling the dialog class DoModal() function, while a modeless dialog is created by calling CreateWindow() followed by ShowWindow(). Once created, they 'run' in that fashion until destroyed.
What are you trying to accomplish by converting from one to the other?
|
|
|
|
|
I was asked that question in an interview, i told him the creation part that there is difference in creating the dialog but i was not sure about converting one to the other.
Thanks for your answer. Appreciate it.

You can read from the USB port via ReadFile().

This is not absolutely correct. What you do in fact is access the driver of a specific device that sits on the bus. I am not sure, but I think the driver can answer what it wants to the ReadFile() 'request'.
Also, you will only access one device on the bus, not be able to read the USB port activity.

I realize that. The device will need to be located using the SetupDiXXX() functions to enumerate all instances of the device's interface and get the device path to them. The path can then be passed to CreateFile(). With the handle that CreateFile() returns, ReadFile() can be used.

Right, that's why I clarified the OP's request.

Hi,
I want to make a program for Arabic language.I know that arabic is written from right to left.I tried some ways to do that but I was not successful.I think this code should do that:
m_edit1.ModifyStyleEx(NULL,WS_EX_RTLREADING);
But it is not working.What could be the problem?Is there any way to make right-to-left everything on the screen?
Thanks,
ibrahim

Which means what? Have you tried adding that style at design time rather than at run time?
