Re: System Memory Management??

You are absolutely right, but let say, we will have no more memory leaks, and the server should receive an increased ammount of traffic: should't be nice to set the server to send an allert to webmaster, warning that he need a better machine? Confused | :confused:

Programatically set Internet Explorer

Hello gurus!

I face the folowing problem: I develop an application and when user install it, the setup program has to change programatically the Internet Explorer Browser settings.

Can anyone point me in a direction??? I have no ideea, where to start. Are the settings stored in registers? Or is another way?? (More specifically: I want to change the settings of using a proxy).

And if is possible, the same question for Netscape Navigator.

Many thanks,

Mihai

I believe the proxy settings are stored in the registry. A while back I helped create a IE package at work and I am pretty sure all the proxy settings are stored in the registry. Sorry I can't be any more specific.. I'll see if I can dig something up and post it..

WinInet function InternetSetOption is your starting point.
As for Netscape, I'm afraid it is no simple task, you have to edit a file named prefs.js but the whole issue is rather messy.

Thanks for good point you told me, regarding Netscape prefs.js.

For Explorer, I will use the registry key, as I was pointed by another answer.

It is up to you which method you choose to use, but IMHO resorting to InternetSetOption increases your chances that your app will work with upcoming versions of IE.

Generally it is not a good idea to have your app's setup modify user settings. I would be very peeved to find my browser settings tweaked by a setup program without being notified and given the opportunity to cancel.

You can modify Netscape settings by removing it and installing IE. Big Grin | :-D

21-Jan-02 5:27

As already said, it better to not change the IE settings without asking agreement from the user!
Anyway if u still need to do that, it is in the registry under the key:

HK_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

and the values to change is : ProxyServer ( xxx.xxx.xxx.xxx:port )

If u need anything else post it!

MSHTML in app. Is it legal?

21-Jan-02 7:13

Thanks a lot for pointing me in the right direction!

You are absolutely true, I found the setting right where you point me.
And as you say, the user will be prompted about changes.

Am I allowed to distribute an app that uses Microsofts MSHTML or CHtmlView without contacting MS for pemission. I have seen some apps with this in their about box.
"Microsoft Internet Explorer components under licence from Microsoft"

.NET or not .NET? MFC is the question......

Hello!

According to
Redistributing Microsoft Visual C++ 6.0 Applications

Redistributing Web Applications
If your application uses the MFC classes implementing the WebBrowser control (for example, CHtmlView or CHtmlEditView), Microsoft Internet Explorer 4.0 or later must at least be minimally installed on the target computer.

So this means that the user has to install IE4 or later to use your product, but since IE is "free" ...

Two question about window's timer??

hemouse21-Jan-02 1:28

Two question:
1.
My program must monite the communication port in real-time mode,and display the trend-line in the screen,but when i do another long task,such as copy a big file to the floppy disk,
It seem that the program's interface can't updated until this long task has finished,
what shoud I do in such case?
2. when I drag another application's window, It seem that the WM_TIMER message only occured after I release the mouse-button,but I don't want this ,what do I do in such case?

Thanks a lot!

You should create a thread to perform time consuming tasks (such as the file copy) in the background. Alternatively, you can perform the file copy in small chunks, between which you should flush the Windows message queue. The separate thread is the preferred way.

hemouse wrote:

WM_TIMER messages are still being sent as you perform the drag. However, Windows will handle higher priority messages first (eg: WM_MOUSEMOVE). Eventually, all the WM_TIMER messages will be handled as a single one. You need to restructure your logic to account for this.

about first question:
perhaps you have misunderstood my meaning.
I didn't copy the big file in my application.Instead, I switched to the window's explore to do this task, so my application can't handle something(such as update the interface in real-time , send a signal to the comport's DTR when I received some special bytes from the comport),and these only can do after the file's copying is ended.

About question 2:
Can you give me some good advices ?

Hi,

If you must monitor the communication port in real-time mode, do not use WM_TIMER !
Use waitable timers(check the api SetWaitableTimer) or more precise than this
multimedia timers, do a check for this on MSDN.
Anyway WM_TIMER is meant to use in user mode gui applications , not on your type of project.
I've done this kind of development, and WM_TIMER doesn't work well, it have lower priority than waitable timers and multimedia timers(more precise)

Cheers,

I'm developing sth. similar: Data from Serial is displayed in a diagram.
I have a workerthread polling data from serial and adding it to a shreadsave queue. a GDI-thread takes data from the queue and draws a diagramm in the Client area.
