Check out InternetGetConnectedState() on MSDN.

You can check for open PPP-(Point To Point Protocol) connections by calling RasEnumConnections() (see help for params). The function will return the number of active connections. If there is none, you can dial up one by calling RasDial().
Hope this will help you.

Pseudocode is code to demonstrate a concept, not designed to be run.

Has anyone have an idea if there is a Windows API to use in order to Enable/Disable the "Start->Shut down ..." menu in the windows task bar.
In my application, to use it, the user have to enter a code or have an access right.
Thanks

I'm quite new to ATL. I want to know how to implement a C++ like class inheritance in ATL. I understood that we can implement an interface inheritance (e.g. Multiple Dual Interfaces) but this method would only expose one IDispatch to clients not using vtable binding.
Example: I want to have Shape object (or interface) then I want Rectangle and Ellipse objects to inherit the properties of Shape and implement/override methods like GetClipRect, Rotate etc.

Has anyone ever installed a network protocol driver (or any other driver for that matter) programmatically. Our application will require the addition of a network protocol we include with the release and we want to make the installation seamless to the user.
I already have an .INF file and .SYS (driver) file. What I need are some Win32 functions specific to NT which will use the INF file to install the driver. I'm trying to avoid having the user enter the Network Control Panel applet, accessing the Protocol tab and pressing Add Protocol.
Specific sample code would help greatly, but additional direction wouldn't hurt.
I've read all the documentation I can find on SetupDi* API functions, but can't quite come up with a solution which works.
Thanks in advance for ANY help.

I'd like to see some code for doing antialiased lines, polygons, etc., preferably using only GDI. OpenGL and/or DirectX methods would be good too, as long as they are simple and compatible with GDI-based apps

Please send me a link/code piece or full source how can I grab the whole desktop into memory?
I implemented a code what can get the desktop image to memory and it can grab about 2-3 times a second. (awful slow.) I'd like to grab all sizes of desktop and any colors.
(VC++, noMFC, WinNT4.0 SP6, source:1024x768x32, in memory 1 pixel=3bytes RGB and 1 empty byte)
Please reply me if only if you have faster solutions!!!

how do i change the BackGround color of a TitleBar ???
while I'm at it - How do I change the color of the text in
the TitleBar ?
|

You'll need to handle the WM_NCPAINT message, and draw the title bar when that message arrives.

can anyone please give me an axample of starting an application located on the hard drive (c:\myapp.exe) from a button located on a dialog. If the class has already been written plesae point it out to me.
thanks

Very simple -- use the Win32 API CreateProcess() in the button's OnClick() method. CreateProcess() is fully
documented in MSDN -- either on-line with your MSVC 6 compiler, or go to www.msdn.microsoft.com

I would like to see some C++/MFC code that displays an XMLdocument, using the windows IE control. The trick (I think) is that I'd like to use an xsl file to format the data, but just use an IStream to hold the actual XML, rather than a file. I don't think this should be too hard, but I cannot find any examples that use a single application (ie no client server) and a stream, rather than a file for the XML.
Thanks,
|
|

|
|
What I have done is use the CMemFile class and read my data in from a HTTP or FTP stream. I then send that "file" to be processed. I have not used the IE control.
|
|
|
|
|
My problem is connecting the memory object (IStream, I thought, but a CMemFile may be as good, or better) with the xml object (I guess you can use the DOM stuff)and the IE object. I know little/nothing about the available functionality of IE and DOM, except for a quick flick through the documentation. I was hoping some one knew (and had used?) the stuff and could point me in the correct direction.

Hi,
I'm working on writing a text file viewer. Currently in MFC 6.0. It needs to be able to open text files of any size, so can't load it all into RAM at once. If someone has this written already, that would be helpful. I need to be able to adapt it to other file types in the future, but right now just getting it to view (and scroll) a single file of unlimited size is a start.
Thanks for any help.

MSDN contains a free version of MS WordPad with source as an example program. It should be on your MSDN
CD or you can probably download it from www.msdn.microsoft.com.

When installing applications under Windows NT Terminal Server you need to switch the operating system into install mode to ensure all registry settings are replicated out for all users. This can be done from the command line using the command 'change user /install'. The MSDN document that explains this also claims that this can be done progmmatically but doesn't explain how. Does anybody know the Win32 API call to use or registry key to set to acheive this.

Hello,
I've downloaded and used the BandObjs MSDN sample which shows how to create an Explorer Bar.
However, what the sample fails to show is how to communicate between the Explorer Bar and Internet Explorer itself.
What I need to know how to do is the following:
1. When the user enters a new address or clicks on a Favorite, I need my Explorer Bar to know what the new address is.
2. I would like to also be able to *Set* the address of the Browser (IOW "goto" a new website in the same browser window that my Explorer Bar resides).
Thanks much for any articles or help.
- Robert Thompson

You do that by setting up an event handler and listen for "document complete" etc events...
To set a new URL, you use the IWebBrowser2 interface, or even the DHTML Object model (DOM) it exposes.
You get the browser interface passed in the IObjectWithSite::SetSite call.
For a sample of an ATL implementation of an IE Desk band, look at my site:
http://www.viksoe.dk under "ATL, Projects".
