IE Proxy Switcher Deskband

I am currently developing a little IE deskband that gives the user the ability to hotswap between proxy settings with the click of a button, the button then changes to the user knows what the current proxy setting is(Green Means Proxy On|Red Means Proxy off). The one problem I am running into is the fact that it is able to determine the proxy setting when I start IE and thus the button is correctly set, but if I manually change the proxy through IE via Tools -> Internet Options -> Connection Tab -> Lan Settings, the button doesn't update. I was wondering if there is anyway I could envoke a ilstener that would be able to notice when I manaully change the proxy and then set the button based on its current setting after said event. Might be a difficult explanation to understand but if anybody is interested please e-mail me if you want further explanation.

Use RegNotifyChangeKeyValue() to watch this registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

Thanks for pointing me in the right direction Gerald. but I can't quite seem to figure out how to exactly write something that would actively monitor for a change in this registry key. Any help with this would be greatly appreciated. I'm not an expert developer so you'll have to bear with me.

RegNotifyChangeKeyValue monitors the registry key for you. If you use the RegNotifyChangeKeyValue synchronously, then it waits until a subkey has changed before continuing execution. You could use a loop and continue to moniter. If you use RegNotifyChangeKeyValue asynchronously, then you wait on the event instead.

Run the code below. It will wait during the call to RegNotifyChangeKeyValue. Then change your proxy setting through IE and click ok. Then you will see the MessageBox.

#include <tchar.h>
#include <windows.h>


INT WINAPI
  _tWinMain (
    HINSTANCE hInstance,
    HINSTANCE hPrevInstance,
    LPTSTR lpCmdLine,
    INT nCmdShow
)
{
    LONG l = 0L;
    HKEY hKey = {0};
    
    l = RegOpenKeyEx (
            HKEY_CURRENT_USER,
            _T("Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings"),
            0, 
            KEY_NOTIFY,
            &hKey );
            
            
    if(l == ERROR_SUCCESS)
    {
        // The following call will wait until a change is made to the registry key.
        l = RegNotifyChangeKeyValue ( 
                hKey,
                FALSE,
                REG_NOTIFY_CHANGE_LAST_SET,
                NULL,
                FALSE );
                
        MessageBox(NULL, _T("Registry key changed"), _T("Registry key changed"), 0);
        RegCloseKey(hKey);                
    }                

    return 0;
}

Sorry no code. Sigh | :sigh:

(USING TAPI)
I have a program (I wrote) that makes a call via modem to download data. The program has been working on Wind9x/NT4.0 and above for a few years. Now we have an XP machine here that will download with the internal modem, but will cause the program to crash if you use an external modem. Confused | :confused:

If anybody has any ideas! Please pass them on!

Question about GDI+

19-Apr-05 7:24

hi,everyone.
I am learining how to use GDI+.
I do the following things in my programme:
1. Include gdiplus.h
2. Add the gdiplus.lib in Project->Settings->Link-> Object/library modules .
3. Add "using namespace Gdiplus;" at the beginning of the source code.
4. Initialize GDI+ using GdiplusStartup.

but I got a lot of errors:

TryGdipp.exe - 17 error(s), 3 warning(s)

So I includeed
typedef unsigned __int64 ULONG_PTR;
in stdafx.h and there left one error:

Linking...
LINK : fatal error LNK1104: cannot open file "C:\Program.obj"
Error executing link.exe.

TryGdipp.exe - 1 error(s), 0 warning(s)

Can someone tell me how to solve the problem?
Thank you!

to PJ Arends ,thanks your answer.

You need to get the Platform SDK. Alternatively, you can add the right definition of ULONG_PTR:

typedef unsigned long ULONG_PTR;

however you're eventually going to have other compilation errors with your old header files.

MS-DOS Press any key to continue

Is there any way to stop "Press any key to continue" from showing on the MS-DOS window upon the termination of a program written in C++?

Run it from a command prompt rather than the IDE.

Don't run it from the IDE. The "press any key" feature is there so you can read the output of your program before the console disappears, but in a regular cmd session you'll just be back at the command prompt. In VS2005, you'll actually be able to keep the console window around between sessions.

None thatI know of, but there are lots of utilities you can Google for that do this.

I had already seen a few of these utilities, but I just wanted to see if there was something in an existing API that would suit my needs (something I wouldn't have to pay for to distribute w/ my other software). Looks like that isn't possible, Thanks.

Where's Secur32.lib located?

I'm building some code with the following function calls

AcquireCredentialsHandle()
FreeCredentialsHandle()

I've included the header

#include <sspi.h>

which the documentation indicates, however it also says that the "Secur32.lib" library is needed to link with? While the header file is resolved okay, I can not even locate such a library file on my machine. Any thoughts on what could be not setup correctly? I'm using version 6 on Windows 2000, incidentally. Thanks.
