HHOOK SetWindowsHookEx(
int idHook, // type of hook to install
HOOKPROC lpfn, // address of hook procedure
HINSTANCE hMod, // handle to application instance
DWORD dwThreadId // identity of thread to install hook for
);
The fourth parameter is a thread id,not a process id.
While I give it explorer.exe's process id ,the function can't succeed.
How can I do?
In DLL and use Detours.

Hi,
dwThreadId Specifies the identifier of the thread with which the hook procedure is to be associated.U cannot give processid in place of thread.
A process can have only one process id. In a process is a main thread and one or more child threads. So both are different.If you want to hook Explorer window set the threadId(in SetWindowsHook) to 0 then in HookProc check the class name of the Window and if it is "CabinetWClass" using GetClassName API and hook it.
thanks

Thank you very match.
I will try an experiment on it with you said.
But how to get a main thread id with process id?

Hi all,
What function can I use that is similar to URLDownloadToCacheFile but with the ability to download the part of a file that wasnt downloaded if an internet disconnection happens. I am thinking of a windowsupdate type of download which if I stop downloading the updates I can resume where i stopped.
thanks,
Jj

I am having problems with INSERTING 'err' value, where the value always change(dinamic).
The error I am getting at runtime is "too few parameters expected 1". This is a part of the inserting program.
float err;
CDatabase db;
CString SqlString;
db.Open("ODBC;DSN=db");
SqlString="INSERT INTO report(ERROR_VALUE,STATUS) VALUES(err,'OK')";//value of 'err' not statis
db.ExecuteSQL( SqlString );
the program will run properly if syntax of inserting like this.
SqlString="INSERT INTO report(ERROR_VALUE,STATUS) VALUES('err','OK')";
but the output not value of "err", but string "err".
anyone can help me????

I used the following code to show an image in the row of a listcontrol.
LV_ITEM lvi;
CString item,symbol;
symbol = card.Right(1);
int len = card.GetLength();
item = card.Left(len-1);
lvi.mask = LVIF_IMAGE | LVIF_TEXT ;
lvi.iItem = 0;
lvi.iSubItem = isubItem;
lvi.pszText = item.GetBuffer(item.GetLength());
lvi.stateMask = LVIS_STATEIMAGEMASK|LVM_SETITEMSTATE;
if(symbol.CompareNoCase("C")==0)
lvi.iImage = 0;
else if (symbol.CompareNoCase("D")==0)
lvi.iImage = 1;
else if(symbol.CompareNoCase("H")==0)
lvi.iImage = 2;
else if (symbol.CompareNoCase("S")==0)
lvi.iImage = 3;
player1.SetItem(&lvi);
There are 13 columns in the row. and there is only one row.
I wanted the image to be shown in every column of that row. But the image is being shown only in the first column. How to make it.
Thank you

You have to set LVS_EX_SUBITEMIMAGES style inorder to display images in subitem.
player1.SetExtendedStyle( player1.GetExtendedStyle()|LVS_EX_SUBITEMIMAGES );

Hi,
I am getting the problem to select multiple files.And DoModal is returning 2(IDCANCEL). Code is below:
<br />
<br />
TCHAR szFilters[]=_TEXT("All Files (*.*)|*.*||");<br />
CFileDialog fileDlg (TRUE, _TEXT(""), _TEXT(""),OFN_FILEMUSTEXIST|OFN_EXPLORER|OFN_ALLOWMULTISELECT|OFN_HIDEREADONLY, szFilters, this);<br />
<br />
TCHAR * pc = new TCHAR[4096]();<br />
fileDlg.m_ofn.lpstrFile=pc;<br />
fileDlg.m_ofn.nMaxFile = 4096;<br />
int nResVal=fileDlg.DoModal();<br />
<br />
What is the problem with it?

The preblem is in
fileDlg.m_ofn.lpstrFile=pc;<br />
fileDlg.m_ofn.nMaxFile = 4096;
ASAIK you dont have to those parameter. You can get all the files selected using the GetStartPosition and GetNextPathName function.
TCHAR szFilters[]=_TEXT("All Files (*.*)|*.*||");<br />
CFileDialog fileDlg (TRUE, _TEXT(""), _TEXT(""),OFN_FILEMUSTEXIST|OFN_EXPLORER|OFN_ALLOWMULTISELECT|OFN_HIDEREADONLY, szFilters, this);<br />
int nResVal=fileDlg.DoModal();<br />
POSITION pos = fileDlg.GetStartPosition();<br />
while( pos )<br />
{<br />
CString cs = fileDlg.GetNextPathName( pos );<br />
}

Without spacifying size of buffer, how could you get the all files path.
I read to define as on another forum.

Ok. MFC sets a buffer of length 256 in its constructor. But in your case that buffer will not be enough.
Any way just set the first element of the buffer as 0 after allocationg the buffer. Like..
TCHAR szFilters[]=_TEXT("All Files (*.*)|*.*||");<br />
CFileDialog fileDlg (TRUE, _TEXT(""), _TEXT(""),OFN_FILEMUSTEXIST|OFN_EXPLORER|OFN_ALLOWMULTISELECT|OFN_HIDEREADONLY, szFilters, this);<br />
TCHAR * pc = new TCHAR[4096];<br />
pc[0] = 0;<br />
fileDlg.m_ofn.lpstrFile=pc;<br />
int nResVal=fileDlg.DoModal();

I was not able to spot any problem with the code so I just tried your code in a new MFC dialog based application and it is working fine. So I guess problem is somewhere else.

If the number of files you select is causing it to fail, then your buffer is probably too small. With a buffer of 4096 and 160 files, that's only 25 characters per file.
Acccording to MSDN:
If the buffer is too small, the function returns FALSE and the CommDlgExtendedError function returns FNERR_BUFFERTOOSMALL. In this case, the first two bytes of the lpstrFile buffer contain the required size, in bytes or characters.
Hope that helps.

I am trying with VS 2008 under Vista and even if buffer is small I do not get FNERR_BUFFERTOOSMALL. CFileDialog simply return files it can with the given buffer. I couldn't find anything specific to this in MSDN.

I am using VS 2008 on Vista and it works even with 1000 files.

You can call
DWORD error = CommDlgExtendedError();
to find out what exactly is the problem.
