Hello all,
I'm trying to use Microsoft Win32 Detours library (API interception library). Because it is a production of their research lab, they offer no formal support.
At the beginning I had problems compiling the latest version (version 2.1) of the library with MS C++ Express - however, it compiles fine on VS2003.
When compiling the DLL which contains the custom functions (the detour DLL) I get the errors:
<br />
detours.lib(detoured.obj) : error LNK2005: _DllMain@12 already defined in testC.obj<br />
LINK : warning LNK4098: defaultlib 'LIBC' conflicts with use of other libs; use /NODEFAULTLIB:library<br />
Release/testC.dll : fatal error LNK1169: one or more multiply defined symbols found<br />
I did try to use /FORCE:MULTIPLE, which caused a successful compilation. However, when I load the DLL using one of the destours samples (withdll.exe) I get the error:
<br />
Error: testC.dll does not export function with ordinal #1.<br />
I know that this is a library specific question and this forum is for C++ general discussion. However, I have no other place to ask. I was also hoping that I can get an answer since this *looks* like a settings problem.
I did use an older version of Detours library a long time ago and I had no problems.
Detours website: http://research.microsoft.com/sn/detours/
Many thanks in advance,
- Naimi
SOLVED
I did not use a .def file which exports the functions (I did not need to do this with Detours version 1.5)

I develope applications which are mostly standalone Desktop applications. Few applications are of GDI+ and few serial ommunications applications.
If i wanna upgrade from VC6.0 to VS2005
Should i buy Professional Edition which is $799.00
or i would go for Standard edition which is $299.00
Will my applications work properly in standard edition mostly i am worried about GDI+ applications.
Thanks,
Sandip.

they will work fine in both, the editions are not limited by technology, except the express one. They are limited by other features. There would be a feature matrix on the MS site, I am sure.

Ya i went through the Features set i didnt understand few things from there so i was confused.
Will there be much migration issues??.
Thanks,

If there are any, they will be the same for both Professional and Standard.

Hi,
I have a listbox containing strings items. When the user selects an item in the listbox using keyboard character, there is a vertical cursor/caret displayed at the end of first character. E.g. If the listbox has String items as "One", "Two", "Three", "Four", "Five", "Six", "Seven" etc... and the user press character "s/S" after bringing the focus on the listbox, a vertical line similar to the one shown in the following word "S|ix" is dispalyed.
Basically a veritical line is shown after the first character of the item if it exists in the listbox
How do I get rid of this cursor? I have tried using "HideCaret", SetCaretPos API in selectchange message handler, onfocus message handler but the vertical line is still vistible, though it goes away automatically in a second or two, I do not want it to be displayed at anytime.
Thanks.

What does the code look like that creates the control?

Hi Mark,
It is a standard code generated with VC++ 2005. I had simply created a dialog based application. Added a listbox to the dialog and added the code in the InitDialog method to insert the strings in the listbox. When I compile and execute the application the dilaog comes up with the listbox and strings in it, nothing special other than this. Anyways you can see the InitDialog code below where the list box is initialized with strings
CListBoxDialog::OnInitDialog()
{
CDialog::OnInitDialog();
// Other code add by the wizard....
// my code
const TCHAR* Strings[10] = {_T("One"),
_T("Two"),
_T("Three"),
_T("Four"),
_T("Five"),
_T("Six"),
_T("Seven"),
_T("Eight"),
_T("Nine"),
_T("Ten") };
for(int i = 0; i < 10; i ++)
{
m_List.AddString(Strings[i]);
}
return TRUE; // return TRUE unless you set the focus to a control
I didn't made any changes in the properties of the listbox.
Thanks
}

Thanks! Can you post the code from the resource (rc) file for the dialog resource?
That's where the control styles are.
I'm curious because I can't get a caret to appear in a listbox.

Hi Mark,
Here is the code for the Dialog resource
IDD_LISTBOX_DIALOG DIALOGEX 0, 0, 320, 200
STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU
EXSTYLE WS_EX_APPWINDOW
CAPTION "ListBox"
FONT 8, "MS Shell Dlg", 0, 0, 0x1
BEGIN
DEFPUSHBUTTON "OK",IDOK,263,7,50,16
PUSHBUTTON "Cancel",IDCANCEL,263,25,50,16
LISTBOX IDC_LIST,72,31,90,113,LBS_SORT | LBS_NOINTEGRALHEIGHT | WS_VSCROLL | WS_TABSTOP
END
If you want I can send you the zipped code at your mail address
Thanks

Just what I needed, thanks!
 I've never seen that before. I had to look real close to see the caret.
For me, the caret blinks once and goes away (I'm on XP Pro SP2).
I removed the SORT style (set the Sort property to false in the resource editor) from the listbox
control and I don't see the caret now.
I'll look at it more in a bit...

Thanks Mark.
Strange I also do not see the caret if I set the SORT style to false !!
I am also on WinXP Pro SP2 and it goes for me also with in a second. But I had hard time explaining to my usability team about the caret stuff, they are bit rigid on it not appearing at all. And since I also do not know the reason for the caret to appear I thought of creating a seprate project and try to solve the issue and it seems a bit overkill to go for ownerdraw listbox for this issue
But after trying for sometime without luck I had posted it here. Anyways I now have partial solution and till I do not find a proper solution/reason I can set the listbox SORT style to false, sort the items externally and add it to the list.
Regards

The docs for the control mention the caret but I think it's silly on a control that you can't
enter text
WM_SETFOCUS Turns the caret on and sends an LBN_SETFOCUS notification message to the owner of the
list box.
WM_KILLFOCUS Turns the caret off and destroys it. Sends an LBN_KILLFOCUS notification message to
the owner of the list box.
WM_KEYDOWN Processes virtual keys for scrolling. The virtual key is the index of the item to move
the caret to. The selection is not changed.
Cheers,
Mark

you have to use Rpcrt4.lib as stated in the Requirements section of the MSDN page.
(Menu Project->Settings, select the Link, add Rpcrt4.lib in the Object/Library modules textbox).

Hi everyone,
I am using OLEDB APIs (such as CTable, CDynamicAccessor etc) for retrieving data from a text file (say abc.txt).
The problem is while retrieving date value.
When date in "Regional and Language Options in Control Panel" is "M/d/yyyy" format, GetValue of CDynamicAccessor returns correct date value. If i change date format to "d/M/yyyy", GetValue returns NULL.
Can anyone tell me the reason for this behaviour?
Thanks

What format is the date value inside the text file?
The problem recognising D/M/Y versus M/D/Y is that there are a large number of values (where both M and D are <= 12) where it cannot be categorically determined which format is in use.
If the data driver you are using is expecting M/d/yyyy, then in theory you could call SetThreadLocale() while you do the retrieval, and set it back again afterwards, but there's no guarantee that it isn't using LOCALE_SYSTEM_DEFAULT or LOCALE_USER_DEFAULT, rather than calling GetThreadLocale() internally.
