Yeah I thought that might be the case too. So I checked this in the Display options and tried with it turned on and turned off. It made no difference on my machine at all.

You may want to use GetCharABCWidths to calculate the sizing for the width. Also, are you subtracting any scrollbar area, borders or 3D bevel edge sizes (GetSystemMetrics())? These can be different with the new XP themes.

New to Visual C++ and Win32 - How to bring up a window as activated?

Hi,

I'm trying to bring the window of Excel to the foreground. I've tried SetForegroundWindow(), but don't work. I tried SendMessage(), but it seems too complicated to me.

What should I do? I have the hWnd of the excel application, I'm sure it is possible.

Also, where can I get more information on how to send messages to other windows, like submitting mouse clicks and key inputs, much like Sendkeys of VB? When I google "Windows Programming", I only get those discussing message loops, Windows proc etc, but not much about the message sending thing.

Thanks in advance.
Regards,
David Chan

I'm not sure, but probably it isn't because "The process was (not) started by the foreground process(my program)".

Yeah, I read that too, that's why I ask the question here for alternatives other than SetForegroundWindow, or for stuffs that fix the problems that make setfgwindow fail.

DavidCrow wrote:

Actually my code makes Excel run, I use getObject to get the COM object of an Excel Application (say xlApp), and set xlApp.visible to true.

I got hWnd from the xlApp object itself (xlApp.hWnd).

Hi ,
If you have created the excel through code then you can actually ask the COM interface to give the user the control and make it visible(if not visible),
Check this link also regarding Messages :-
http://www.flounder.com/messaging.htm[^]

Following code sets the yahoomessenger in the forground

HWND hwnd = ::FindWindow (NULL,"Yahoo! Messenger with Voice");<br />
::SetForegroundWindow (hwnd);

Automated testing?

Hey thanks! It is a very detailed page on Message API.
However, I have a question. In the article, it said one shouldn't "fake" the system by submiting event msgs like "WM_LBUTTONDOWN", coz I have to make sure that "all the rest of the system state is correct".

However, if I want to do automated testing, and I want to simulate the user's GUI input(just like what the Rational Robot does), I wonder if it is ok for me to do such faking? I mean, would it be very troublesome to achieve that said "all the rest of the system state is correct"?

Or, only better, is there any existing open source automatic GUI testing framework available? I don't mean those xUnit Unit testing frameworks, I mean the GUI ones and provide an API for doing things like getButton(buttonID).click, getWindow(windowID).GetCombo(cboID).selectItem(1), much like the SQABasic scripts?

Thanks!

Including a class in an MFC project

Lilith.C19-Jan-06 5:39

19-Jan-06 5:39

I've made this work but I'm wondering if there's a better way that I'm overlooking.

So, I've developed a sub-class of a CEdit control in a development environment. I've got the two files MyCEdit.cpp and MyCEdit.h sitting in a directory of my development environment. My latest and greatest (at least most time consuming) project needs to use the new class object. I can't use New Class because that means I have to start from scratch. I can't add the class from a type library coz it isn't in one. So all I can do, and have done, is include the two files in my project. At this point the class wizard doesn't appear to know that CMyCEdit exists. Under Member Variables/Add Variable the Variable Type doesn't know that I've just introduced CMyEdit. I include MyCEdit.h in the ??????Dlg.h file and no difference.

In order to make the class appear in the class wizard I have to make sure that the class header file is #included in either the dialog or view header. I then delete/rename the .CLW file, invoke the class wizard which then offers to rebuild the class data from the files involved.

Certainly there has to be a better way to do this more directly through VC++. Confused | :confused:

TIA,
Lilith

Not necessarily. Deleting a project's temporary files (e.g., ncb, opt, clw, aps) is actually quite common.

Another COM port question

How can I check if a device is connected to my serial port?

Using CreateFile on COM1 I can get a HANDLE to the file, but I don't know how to use that to tell if something is actually connected.

Thanks!

Send some command to ur device. if it did not respond then its not working either connected or not connected.

The problem is that I know basically nothing about the device. I was hoping there was a generic WinAPI command or something that I could send to see if it was responding, like a ping or whatnot.

CreateFile should succeed as long as there is a COM port. The only problem you will have is if the COM port is already being used by another application. If it is, CreateFile will fail. If the COM port does not exist, CreateFile will fail.

What exactly do you want to detect is on the COM port and why?

You have to get informations regarding the device connected to your COM port. Otherwise there is now way to detect the device is connected or not. But in case of USB device, u can get information of USB device connected without knowing the details.

This is just a guess, but does the following help:

OVERLAPPED ov = {0};
HANDLE hCom = CreateFile("COM1", ..., FILE_FLAG_OVERLAPPED, ...);
SetCommMask(hCom, EV_CTS | EV_DSR);
o.hEvent = CreateEvent(NULL, FALSE, FALSE, NULL);
if (WaitCommEvent(hCom, &dwEventMask, &o))
{
}

What is that you want to do with that DOS interrupt? what service are you trying to use?

Windows has pretty much all the APIs that you could do with DOS interrupt 21h, Try that intead.

they are not text files, they are binary files, so, if you use fscanf(), cin or such basic functions, you'll get "strange" data.
