How does one debug an Application Wizard designed for Visual Studio 2003 .NET?
Mostly I want to debug the JScript part of it. On Internet Explorer I have set the option of "Disable Script debugging" to No. When I open one of the HTML files and I answer yes to the question of wanting to debug the script nothing happens.
I am the handsome one in the crowd.

Check maybe you need to define _WIN32_WINNT to be 0x0500

Thank you for the reply.
I have defined _WIN32_WINNT, but still it does not compile.
What I notice in my system is that QueueUserWorkItem(...) declaration is present in the "winbase.h" header file found in my [C:\Program Files\Microsoft SDK\include] folder. But the VC++ IDE is including the "winbase.h" from folder [C:\Program Files\Microsoft Visual Studio\VC98\Include] which does not have the declaration for QueueUserWorkItem(...)
Can you figure out what is wrong for my app not to compile?
Regards,
Senthil.

In the IDE you can change the order in which the Include folders are searched. Make sure the (February '01) SDK version is at the top of the list.

Go to Tools->Options and click on the "Directories" tab.
Change the order in the list.

Hi guys
I need to get an XML file from internet and parse it to get some values.
I'm newbie in these kind of things.
I've seen XmlViewer class here in CodeProject pretty good (it only read files from HD I think) but to read a file from internet what is supossed that I have to do?
I repeat that I'm newbie working with internet files.
Could you redirect me to an example that shows how to get and open an internet file, maybe with this and with the XmlViewer found here in Codeproject it will be enough to understand and do what I have to do.
Thanks in forwarding

Hello !
Looking in the MSDN for the documentation about using timeouts with serial ports (using the COMMTIMEOUTS structure), I found this line:
A value of zero for both the ReadTotalTimeoutMultiplier and ReadTotalTimeoutConstant members indicates
that total time-outs are not used for read operations.
But what does 'total time-outs are not used' means ? Does it means that the read operation will return immediately even if no bytes were received or does it wait an infinite amount of time (till all bytes are received) ? It is not really clear...
And the same question for write timeouts.
Any idea ?
Thanks

I am pretty sure, based on my experiences, that it means the read will WAIT nearly forever.
You really DO want some timeouts, and then just accept what characters you have and accumulate them into your own buffer until you have the desired amount of characters, or consider it an error condition if you have not received enough in the alloted time.
Same for writing. If they don't go out the port right away, in the alloted time frame, then something else is probably wrong, like the modem is off or the serial line is disconnected or something.
I would not recommend writing code that will 'wait forever' in either case if you can help it.
If you don't expect the same amount of data to be read or written constantly, there is the SetCommTimeouts() function you can call prior to each read and write. Use some math to adjust the time frame estimate based upon your current bit rate and the number of characters.

Need to write a driver(virtual serial port driver) in C/C++ which will fit in between the applications and the USB driver, and will try to expose virtual serial ports which the application can communicate with, and internally will pass on data to the USB layer, which will communicate with the USB end of the connector.
For applications, even though the serial devices are connected through a USB interface in between, the USB interface is transparent – i.e. the applications must behave as if they are communicating with serial devices through COM ports, USB is nowhere in the picture.

Hi.
I am creating the Outlook Object Library 11.0's application object in C++ and calling its CreateDispatch method in an MFC Regular DLL's exproted function. When i call that function from a windows application it is working fine, but when that function is called from a windows service the CreateDispatch function of the application object fails. Please tell me what is this problem. The windows service is configuered to run with a user of windows NT domain.
Here is the code
if(objApplication.CreateDispatch("{0006F03A-0000-0000-C000-000000000046}"))
{
objNameSpace = objApplication.GetNamespace("MAPI");
if(objNameSpace!=NULL)
{
isLoggedIn=TRUE;
return TRUE;
}
}
isLoggedIn=FALSE;
return FALSE;

Your SERVICE might be configured to run as the user of the domain, but that does not mean that the MAPI code does not make its own calls to try to resolve the 'current user' and it does not find one logged in. I think there are articles from Microsoft and some here and there on the Internet that discuss problems with using MAPI from a service.

It is time to admit that I am out of my element. I am new to Visual C++ .Net and need help.
How do you create and access Global Variables in a Windows Form Application. I have vaiables that I need to access from several different forms. It is possible?
Thanks

Thanks, I am closer.
When I follow those instrutions, I place the variable (int iTest;) in a .cpp file outside form1 and form2. Also, place "extern int iTest;" in stdafx.h It allows me to assign "iTest = 6;" in form1, but when I insert "iTest = 23;" in a button_click on form2 I get: " 'iTest' : undeclared identifier" and " 'iTest' : redifinition; different basic types".

Did you try rebuilding the application? Things in stdafx.h are precompiled and will be regenerated only by a rebuild.

Actually ther problem I caused is that I had included the Form2 *before* I declared my global in stdafx.h. This caused the program to try and reinitialize the variable again.
Whew! I think I can actually do this!
Thanks guys, I am learning, but apparently I used punchcards to many times in the early days.
