Hi all
I want to enumerate all the ports of my PC( e.g. Primary IDE, secondary IDE,COM1, COM 2, LPT1, PS/2 etc.).
How can I achieve this, either by using MFC or any API or any other way.
Please Reply
Thanks & Regards.

Hello guys out there. I've been doing my project and have some additional functions/codes I added. When I try to compile it returns some error.
The compiling error is shown like this:
--------------------Configuration: WebJudge - Win32 Debug--------------------
Compiling...
MyProjectView.cpp
C:\Program Files\Microsoft Visual Studio\MyProjects\MyProject\MyProjectView.cpp(225) : error C2228: left of '.InsertRowTable' must have class/struct/union type
C:\Program Files\Microsoft Visual Studio\MyProjects\MyProject\MyProjectView.cpp(228) : error C2228: left of '.WriteHtmlFile' must have class/struct/union type
Error executing cl.exe.
MyProject.exe - 2 error(s), 0 warning(s)
-----------
From my MyProjectView.cpp (where the error is):
void CMyProjectView::CreateHtmlFile()
{
CPtrArray* pPageInfos = CDatabase::GetInstance()->GetPageInfo();
CHtmlEdit oHtmlEdit();
for (int nIndex = 0; nIndex < pPageInfos->GetSize(); nIndex++)
{
CPageInfo *pPageInfo = (CPageInfo*)pPageInfos->GetAt(nIndex);
oHtmlEdit.InsertRowTable(nIndex, pPageInfo->ToString());
}
oHtmlEdit.WriteHtmlFile("./demo.htm");
}
----------------
Can someone out there, what went wrong with my code? I really don't know how I will solve that.
Thanks and best regards.
With great power comes a great responsibility.

have u added header for class CHtmlEdit. that might be possible reason.

Hello
It seems to me you try to create an object of type CHtmlEdit . So, I think You have to remove () from the following statement:
CHtmlEdit oHtmlEdit();
If you omit the paranthesis, an object is created and the default constructor is automatically called.
I hope this solves your problem.

Hello,
I need to make my window to be the background window of some of currently running windows (eg. all notepad windows).
When the user activates the notepad (one of the running notepad or opening a new one), my application should come to top, but behind all the notepads.
Similarly if the user activates my window, the same thing should be happened.
In other words, my window needs to be the background of all the notepads.
Does anybody have an idea to solve this problem?

Do you mean, your window should be "behind" all notepads windows ? Or should the background of the notepad window (the white surface on which you write the text) be your window ?

Yes, I want my window to be behind all the notepad windows.

In my attempts to make my program as versatile as possible I followed all the advice given about using TCHAR's and the _T macro so that my code could be compiled in both the ansi standard and the UNICODE standard. However i have run into a wall now which suggests i am not understanding something.....
in this line:
sFontDetails.FaceName = _T("Times New Roman");
i get the error:
error C2440: '=' : cannot convert from 'const unsigned short [16]' to 'WCHAR [32]'
I was under the impression that the _T macro when used with a string literal should be automatically converted to the WCHAR[] type or the normal char[] type depending on whether i have the line #define UNICODE in my program or not..... what am i missing?
Thanks in advance,
Ed Bosher

did you defined those two constants :
stdafx.h :
#define _UNICODE
#define UNICODE
do it at the beginning of the stdafx.h file...

What is the type of 'FaceName'?

no, _T() is declared for both Unicode and ansi. this is for allowing compilation for unicode and ansi without changing the code...

Ok thx didn't know that but still, I have definately declared both the UNICODE macros, if I remove them it says:
error C2440: '=' : cannot convert from 'const char [16]' to 'CHAR [32]'
instead of (with #define _UNICODE and #define UNICODE):
error C2440: '=' : cannot convert from 'const unsigned short [16]' to 'WCHAR [32]'
So maybe the question is why is the UNICODE macros turning my string into and unsigned short and not a WCHAR?

because the operator = () don't copy the contents of the C-style strings but only the addresses of the pointers...
does this error occur with strcpy() ? i doubt...
you could use strncpy() also if you want to copy not the totality of the string but a part...

Yes it is WCHAR, I have already included the #define UNICODE and #define _UNICODE line, if I hadn't i believe it would have a different error along the lines that _T would not be a declared macro....

it is just as if you were doing this :
char* psz = "Hello";
char tab[10];
tab = psz;
use <a href = "http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_strcpy.2c_.wcscpy.2c_._mbscpy.asp" rel="nofollow">strcpy()</a>[<a href = "http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_strcpy.2c_.wcscpy.2c_._mbscpy.asp" target = "_blank" rel="nofollow">^</a>] and/or wcscpy()
