Hey
I have an app that needs to be able to connect to the internet at anytime, unattended, day or night. What I have done in the past is called InternetAttemptConnect(). But in order for this to work I had to make sure that I allowed my dialup connection to connect automatically. But thanks to some poorly written apps (Firefox, ZoneAlarm) that option is no longer becoming viable as those apps are also able to connect at any time (and they do). So what I did was change the connection call from InternetAttemptConnect() to InternetAutodial(INTERNET_AUTODIAL_FORCE_UNATTENDED,...) which allows me to clear the automatically connect flag in the dialup dialog and still be able to make the internet connection my app has to make, but stop the other apps from doing the same.
But that has lead to another problem. If the dialup dialog is started by one of the other apps and is waiting for user input, InternetAutodial will also hang, waiting for the same user input.
So what I would like to know is if there is an API or other way of telling if the dialup dialog is already present, and if so how can I kill it so that my call to InternetAutodial() will succeed? I could use FindWindow to look for a dialog with the caption "Dial-up Connection" but to me that just doesn't seem to be a very safe or portable way to it.

Do you know what process owns that dialog?

Agreed.

No, If I did I could do a search by processID.

Does the dialog show up on the Applications tab of Task Manager?

No, but according to Spy++ it is a top level window.

That's unfortunate. One of my computers uses AT&T Global Network Client and its process is netclient.exe.

It's the standard windows/IE dialup connection dialog box. It is used by almost every app I have that needs an internet connection. Only MS Outlook 2000 uses a different one that does not interfere with my app.

Ahhh, it's been a while since I used that one. It seems like it would belong to the explorer.exe process. Yes? Not that that's any more help, however.

One would think so. But according to spy++ it belongs to the process that started it. That is how I figured out that firefox and zonealarm are popping the dialog up at random points in time.

No, it's not.

This might be overkill, but perhaps you could set up a second (non-default) connection that will be used only by this program, and connect through it using InternetDial()?

That may just work!
Now all I have to do is figure out how to programatically set up a second connection. It would have to be either through my app or have a seperate app that does this via my app's installer.
I am not a network/dialup person so any hints as to APIs to use would be helpful.
Thanks Josh for the pointer in the hopefully right direction.

I'm not really familiar with any of this either... just glancing over the Remote Access APIs is a bit intimidating. Might still be worth a look though, especially if you can dig up some sample code.

Use:
RASENTRY re = {0};
re.dwSize = sizeof(re);
lstrcpy(re.szAreaCode, ???);
lstrcpy(re.szLocalPhoneNumber, ???);
RasSetEntryProperties(NULL, "Second Connection", &re, sizeof(re), NULL, 0);You might then have to call:
RASDIALPARAMS rdp = {0};
rdp.dwSize = sizeof(rdp);
lstrcpy(rdp.szUserName, "PJ");
lstrcpy(rdp.szPassword, "pwd");
lstrcpy(rdp.szEntryName, "Second Connection");
RasSetEntryDialParams(NULL, &rdp, FALSE);

Thanks David, I will look into these functions.

I am writing a program that does installations similar to InstallShield or MindVision's Installer VISE. I know that a good installer should have an option to allow the user to select an install directory but I was wondering if there was any alternative to SHBrowseForFolder() that is more flexible to browse for folders without writing a total custom dialog.
Pplshero54 thanks you for your assistance

What is it (not) doing?

Sorry, i meant that is there a way to specify a starting folder, create folders, and/or limit the user to select locations on a hard drive by using SHBrowseForFolder().

What's wrong with:
BROWSEINFO bi = {0};
char szFolder[MAX_PATH];
bi.hwndOwner = GetSafeHwnd();
bi.lpszTitle = szFolder;
bi.ulFlags = BIF_USENEWUI;
SHBrowseForFolder(&bi);pplshero54 wrote: ...and/or limit the user to select locations on a hard drive by using SHBrowseForFolder().
I prefer to do this at the OS level. You have more control and the code does not need to change if more/less security is needed.

Hi,
I have a litle problem with compiling my help files. The application I'm developing is an MDI app created with the Visual studio wizard and has WinHelp. I created my own html help and I don't have the need for winhelp in my program any more so the question is how can I compile my program without winhelp or let's say how can I extract winhelp from the app?
Thanks

Remove it from the project's dependencies.

I know in a program , you can create some threads,and assign different priority
my question is: how to programmtically give your main thread the highest priority? Thanks alot!
|
|
|
|
|
The SetPriorityClass function sets the priority class for the specified process. This value together with the priority value of each thread of the process determines each thread's base priority level.

Why would you want to do this? It would all but totally disable the OS.

Here is the reason:
Say I am testing the speed (I/O reading writting).
I want the Max performance , the code would be like:
tStart = getCurrentTime();
do{
reading();
writting();
}
span = getCurrentTime()- tSpan;
How can I ensure those steps are not interupted?
|

|
|

The first thing to note is that GetCurrentTime() has been deprecated by GetTickCount(). Second, calling SetThreadPriority() with a priority greater than 11 may cause disk caches to not flush, hang the mouse, and so on.

By using a critical section (e.g., InitializeCriticalSection()). I'm not sure you actually want to do this, however.
If you are simply wanting to time a section of code, GetTickCount() is the way to do this. Since Windows is not a RTOS, you'll not ever get 100% accuracy. For example, let's say that, per your watch, the code took 5 seconds to execute. However, span had a value of 6000, or 6 seconds. That means that the code was preempted for a total of 1000 ms. This is not necessarily a bad thing. It's much like weighing yourself at home on a scale that is not 100% accurate. Whether it shows you to be too heavy or too light, it doesn't matter as long as it's consistent. By comparing one weigh with another from the same scale, you can judge for yourself whether you are gaining or losing weight. Make sense?
