i thought the full duplex project was a voip application and was using it as a reference to build my own voip system, however i have now discovered that it only works over the data link layer and as such is not a voip system. Could you please tell how i could modify it, or how i would be able to implement a system which sends voice traffic over the IP layer using UDP as i have no idea where to start. i probably have to create and bind sockets with datagrams or something like that butim not sure how i would incorporate it into the project.
I would be very grateful for any help.
thanks

Gee, this is a very precise explanation of the problem. What do you mean by 'work well' ?

ShellExecute. This is surely in the FAQ ?

Yes, you need to work out what dependancies your project has ( such as MFC ) and ship your program with the DLL's that it is attempting to load.

It was OK until this point actually I think you mean 'English'.

Can you make it read-only or disabled?

How would it be possible to send a "Print Screen" keydown message or whatever?
Which message should I send with which params (if possible)
Thanks a lot

You could manually send a WM_KEYDOWN and a WM_KEYUP message, but it's a bit tricky setting up all the flags and what have you.
A better way is to use a function for that specific purpose, keybd_event. Look it up in MSDN. Use it something like keybd_event(VK_PRINTSCREEN, ...);
If you are trying to simulate a printscreen to do a screen capture and put it onto the clipbopard, a better way is to call GetDc(NULL) to get the DC for the desktop, then grab the bitmap out of the DC and slap it on the clipboard.

Thanks a lot, just a little more question about it.
I want to simulate that printscreen key in a specific window that is minimized... I've tried adding ' :: ' in front of the keybd_event function, however it still does not take any HWND parameter....

|

Found it!!!
Thanks a lot man, without that keybd_event function I couldn't have guessed it.
Thanks!!

Hi,
I was trying to build an ATL VC++ program in .net 2003 and I keep getting LNK 2019 errors. In the MSDN I searched for that error and I found the following. Can anybody tell me where I can find _check_commonlanguageruntime_version function and where to put that?
In Visual C++ .NET 2003, this error will be generated when /clr is used and the CRT is not linked into your executable. Any object code generated by the compiler that is not built with /clr:initialAppDomain contains a reference to the _check_commonlanguageruntime_version function, which is defined in the C Runtime Library (CRT). This function provides for an error message if your application is run on version 1 of the runtime. Code generated by the current compiler is not compatible with version 1 of the common language runtime. So, if you compile without the CRT in Visual C++ .NET 2003, you should include a definition of the _check_commonlanguageruntime_version function in your code. As an alternative to using the _check_commonlanguageruntime_version function, you can link with nochkclr.obj, which contains an empty version of the function and does not provide for an error message if you run your application on version 1 of the runtime. To build an application with the current compiler version to run on the previous version of the runtime, use /clr:InitialAppDomain.

I was trying to build a atl program in .net, I got this error
error C3861: '_L': identifier not found, even with argument-dependent lookup
on the line
if( lstrcmpiW(szName, _L("Output")) == 0 )
..............
What should I use instead of _L ()?

"string" = ascii 8-bit character string
L"string" = unicode 16-bit character string
#ifdef _UNICODE
_T("string") = L"string" = unicode 16-bit character string
#else
_T("string") = "string" = ascii 8-bit character string
#endif

Shouldn't it be:
if (lstrcmpiW(szName, L"Output") == 0) or
if (lstrcmpiW(szName, _T("Output")) == 0)

Thanks to those who answered my last message. Now, I've found a way to actually LOOK at the database, and I can connect to the DSN. The only problem is: How do I connect to the actual database that I want. I mean, there's like 6 databases in that DSN, and only one of them is the one I want, the rest are master, model, msdb, etc.... How to I access the one I want. I tried doing an INSERT INTO statement to the table I wanted, but it failed (I can only assume it's because I don't yet know how to specify which database it is). Thanks for any help you can give me.

You have many options:
1)Specify the database in the ODBC DSN
2)Specify the full qualifier in your statements (select * from MyDB..MyTable, insert into MyDB..MyTable...)
3)Do a SQLExecDirect of "use MyDB"
onwards and upwards...

A DSN is tied to only one database at a time. When you created the DSN through the ODBC applet in Control Panel, you were asked to pick the database. I've used DSNs with both Access and SQL databases, and aside from how the actual DSN dialog box looks and behaves, it's a 1:1 relationship.
I may be way off base here. If so, please provide a small code snippet to help clarify the issue(s).

Hello,
Over the last few weeks I have been writing a win32 application not using MFC and I have come up against a problem. I'm trying to figure out how to add a toolbar with icon buttons and a combo box below it. To get an idea of what I want here's a picture: http://k1studios.com/images/trav.gif.As you can see I want to have that exact layout but I have no idea how to develope that since I don't have the help of MFC. So if anybody has any idea I would REALLY appreciate it.  Thank you, Caleb
