On the uninstall section of an application I wrote I have added a shellexecute command which opens the application.
When I run the uninstall from the add\remove programs on win 2000/XP the add\remove programs window , the add\remove program window remaines locked even though the uninstall process has terminated - it seems that running the shellexecute command from the uninstall process is causing this problem.
Can you offer an advise how to overcome this problem?

Hi,
My name is Michael. I am trying to find a way I can print out an opened browser's x,y,width and length coordinates (like I can with a regular mainframe using the CWnd::GetWindowRect function call). I also want to do other things like count how many images are currently in the browser and get each x,y,width and length from all the images.
What I tried doing was use a loop with a CWnd pointer called wnd that was initialized to point at 'this' (the program's dialog box) before the loop started. Then, I used..
wnd = wnd->GetNextWindow(GW_HWNDPREV);
to point at previous windows in the memory bank, stored the name of each window on a string and kept getting previous windows until ::IsWindow(wnd) was false or until the string "- Netscape" was found within the string. Then I used another loop with...
wnd = wnd->GetNextWindow(GW_HWNDNEXT);
in it instead (to get next windows). Then, when the computer finally found the pointer to any Netscape Browser that was opened, the loop would then terminate. I then used
wnd->GetWindowText(str);
AfxMessageBox(str);
to test it out and it worked! but when I used
wnd->GetWindowRect(size);
I would get some strange numbers until I either minimized or maxamized the browser. Then I would get 0, 0, 600, 800 when the browser was minimized and a constant values between 0 and 600 (for x), 0 and 800 (for y), 0 and 600 (for width), 0 and 800 (for height) and no matter if I resize the browser window, I would get the same numbers. Also, SetWindowText wouldn't work. I found out I need to use something like...
CComPtr<iwebbrowser2> browser;
CComPtr<iserviceprovider> isp;
but I don't know how to use these.
Thank you for any help,
Michael S. Lowe

How do we detect tone/pulse coming into a modem from a standard telephone? I am using CreateFile to connect to the modem and ReadFile/WriteFile for I/O.
|
|
|
|
|
Typically you need to program the modem to go into voice mode and then it will send you escaped character sequenes to indicate which tones have been detected.

How can we make the modem go into voice mode?

This is found in winioctl.h.

This question is a bit vague, but does NetUserGetInfo() do what you require?

Hello all,
I am stuck at a problem where I am supposed to communicate with a telephone using a modem. I am using the API functions of CreateFile, ReadFile, and WriteFile for this purpose. I need to send phone pulses to the other end and receive pulses from the other end. I have managed to establish connection and send pulses to the remote telephone but I cannot receive the pulses the remote telephone is sending me. Is there a special modem command for this? Do I need a special setting? Help, I am stuck!

You should use TAPI (Telephony API) instead of Win32 CreateFile. See Visual Studio docs or MSDN for a reference and examples. TAPI is installed with Platform SDK, so it comes bundled with most Visual Studio distributions, and/or you can download it from the Internet as well.
TAPI has a function pair called lineGenerateDigits and lineGatherDigits that generate and gather pulse sequences that represent numbers. You can also send and monitor individual pulses with lineGenerateTone and lineMonitorTone.
These functions only exists in TAPI version 2.x. In version 3.x, the COM model is introduced, and everything running on the phone line is considered a stream, with terminal objects acting as sinks. For your case, I suggest TAPI 2.x, if possible. The COM model is too complex for the functionality you require.

How can I implement timer in in Windows (2000/XP )with resolution of 1 milisecond
or better. Multimedia timer seems to be not accurate enough, but may be I am not using it right?
Thanks

Bear in mind that although you can use QueryPerformanceCounter() to get an accurate elapsed time, you *cannot* get things to happen regularly at for example 1ms intervals.
Windows has an internal "clock" of (from memory) 12.5ms, and doing anything more often than that (reliably) just doesn't work.

Close. For Windows 9x/Me, the system clock ticks at 55 ms. For Windows NT, it ticks at 10 ms. This is the best that can be obtained with a non-RTOS system.

Hi,
I'm trying to custom draw a list control. I'm also using it as a virtual list supplying data handling the LVN_GETDISPINFO message. I've handled the NM_CUSTOMDRAW to custom draw only specific Items the problem is the iSubItem variable in the LPNMLVCUSTOMDRAW structure is always zero when I'm expecting it to change. I'm depending on it to idententify which item / subitem it is currently drawing. this I'm doing when dwDrawStage == CDDS_ITEMPREPAINT. am i doing something wrong here. I've seen a sample application XListCtrl in this site which seems to work. am i doing something wrong here. please give me directions as to how to resolve this problem. thanks in advance.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

I'm working on a filter funtion which filters the items in the list control. The items that I inserted into the list control have three attributes which is "creation time", "readed or not" and "item color"(because these attribute are specific to me, so I generalized them a little). what I'm trying to accomplish is to filter what appears in the list control according these three attribute of each item.
I'v got three comboboxs as the user interface which is according to the three attributes. They have the following content.
"creation time" combobox "readed or not" combobox "item color"
->today ->all ->red
->recent 3 days ->readed ->green
->recent week ->not readed ->black
->recent month
->all time
I am not famaliar with algorithm, but I am sure with algorithm I can come up with a very concise and clear flitering logic.But now I just trying to solve the problem too;)!
Can anybody provide a pseudo code or simple algorithm?
thanks!

Here is a generalization:
PopulateListControl()
{
date = value from "creation time" combobox
read = value from "read or not" combobox
color = value from "color" combobox
for (int x = 0; x < number_of_items; x++)
{
if (item.date == date && item.read == read && item.color == color)
insert item into list control
}
}Does this make sense?
