Thanks for that, i have resolved one of my problem.

Hi!
You can do it lie this:
CString er="rui\r\n";
CString ff="santiago";
AfxMessageBox(er+ff);
you'll get
rui
santiago
Using \r\n you'll get the line feed.
Hope this helps

Hi,
I am using Visual C++ 6.0, in my project I create a ListControl which has 3 Header columns as Column1, Column2,Column3 (very simple).
When program is running, I would like to detect which "Header" Column that the user is selecting (Column1, 2 or 3) to proceed one particular function for that column
For now I am using Event: OnColumnclick() and success to know the user click on Header Columns ... but I still do not know which Column?
Can someone help me on this?
Note: Please remember detect mouse position is not help in this case, because user can adjust the column width on run time and it is difficult to calculate update range on Run Time. Imagine there are more columns & some out of the screen, then the user move Horzontal scroll bar to see the last 10 then selecting one ...!
I appreciate any one can help in this case.

iSubItem member of NM_LISTVIEW (or NMLISTVIEW) identifies the column clicked.

add the message handler..
ON_NOTIFY(HDN_ITEMCLICK, 0, OnHdnItemclickMylist)
add the function.. basicly you just check what column it was that was clicked.. i dunno how you would do it if you could rearrange the columns.. but as long as the columns stay in the same order you should be alright..
void CMyDialog::OnHdnItemclickMylist(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMHEADER phdr = reinterpret_cast<LPNMHEADER>(pNMHDR);
if (phdr->iItem == 1)
OnSortNum();
else if (phdr->iItem == 0)
OnSortName();
*pResult = 0;
}

Thank you for your help it works ... even the LPNMHEADER phdr = reinterpret_cast(pNMHDR); compile error I changed to this: HD_NOTIFY *phdn = (HD_NOTIFY *) pNMHDR;
Thank you for help, I am really appreciate it!

Hi! I'm working on a application that uses MSAccess database, i run SQL commands like :
kl.Format("%s%s%s","SELECT Maquina.nicname FROM Maquina WHERE Maquina.maquinaid='", machineid,"'");
pRst->Open((_bstr_t)kl, strConn, adOpenStatic, adLockReadOnly, adCmdText);
Therefor, to use this commands i need this two variables :
_RecordsetPtr pRst("ADODB.Recordset");
_bstr_t strConn("DRIVER={Microsoft Access Driver (*.mdb)};DBQ=proteres.mdb");
I've been defining them locally in all my functions, but now i was trying to make them global for the all application, or even the same class, but i get always the same compile errors for the declaration:
error C2059: syntax error : 'string'
error C2059: syntax error : 'string'
I tried to declare them like:
class CMachine_financial_information : public CDialog
{
// Construction
public:
CMachine_financial_information(CWnd* pParent = NULL, CString maquina=""); // standard constructor
// Dialog Data
//{{AFX_DATA(CMachine_financial_information)
enum { IDD = IDDU_MACHINE_FINANCIAL_INFORMATION };
CListCtrl m_lstcFinanceiro;
CString m_static_tempo;
CString m_static_collected_money;
//}}AFX_DATA
// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CMachine_financial_information)
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
//}}AFX_VIRTUAL
public:
LVITEM lvi;
SortInfo m_SortInfo;
CCtrlSort m_CtrlSort;
----> _RecordsetPtr pRst("ADODB.Recordset"); <------
----> _bstr_t strConn("DRIVER={Microsoft Access Driver <------(*.mdb)};DBQ=proteres.mdb");
// Implementation
protected:
//{{AFX_MSG(CMachine_financial_information)
virtual BOOL OnInitDialog();
afx_msg void OnSelchangecomboperiod();
virtual void OnCancel();
afx_msg void Oncancel();
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
private:
void dinheirocofre(CString, int);
void enchelistctrl(CString);
CString machine;
};
Can anyone help me with this problem?
Thank you in advance

I don't think you can initialize the _bstr_t in the header at least not with that syntax
----> _RecordsetPtr pRst("ADODB.Recordset"); <------
----> _bstr_t strConn("DRIVER={Microsoft Access Driver <------(*.mdb)};DBQ=proteres.mdb");

Thanks, do you think i should cast them into another data tye, which should be the best option?
Thank you

How can I get the name of the program that have created a window given its HWND

Thanks you.
It seems more difficult than I thought!!!

Yea it is. Getting the PID is not the problem, as you can see. Getting the process name from the PID is difficult.
But there is an easier solution if PSAPI.DLL is installed. By default it is there on W2K and XP, redistributable for NT is available. No support for 95/98/Me. Here is how I use it:
In my constructor I have something like
HINSTANCE hInst;
m_pfGetModuleBaseName = NULL;
m_pfEnumProcessModules = NULL;
hInst = LoadLibrary (_T("psapi.dll"));
if (hInst != NULL)
{
m_pfGetModuleBaseName = (GETMODULEBASENAME) GetProcAddress (hInst, _T("GetModuleBaseNameA"));
m_pfEnumProcessModules = (ENUMPROCESSMODULES)GetProcAddress (hInst, _T("EnumProcessModules"));
FreeLibrary (hInst);
}
}
Then I use it as follows
HANDLE hProc;
HMODULE ahMod[10];
DWORD dwNeeded;
BOOL bStatus = FALSE;
char szProcessName[80];
rStrProcessName = "";
if (m_pfEnumProcessModules == NULL || m_pfGetModuleBaseName == NULL)
return (FALSE);
// Need to get a handle to the process so we can query the modules
hProc = OpenProcess (PROCESS_QUERY_INFORMATION|PROCESS_VM_READ, FALSE, dwPID);
if (hProc)
{
// Get the first few modules. The .exe is always the first one.
if (m_pfEnumProcessModules (hProc, ahMod, sizeof(ahMod), &dwNeeded))
{
// Get the exe name. It is always the first module.
if (m_pfGetModuleBaseName (hProc, ahMod[0], szProcessName, sizeof(szProcessName)))
{
rStrProcessName = szProcessName;
bStatus = TRUE;
}
}
CloseHandle (hProc);
}
return (bStatus);
}

In the source code from the URL: The function RegQueryValueEx has as first parameter HKEY_PERFORMANCE_DATA but this key is only available for NT/2k/XP. How can I make this function works with 98/NT/2000/XP?

Ah the joys of enumerating process under the different versions of Windows. For 95/98 the best method is to use the ToolHelp API. See the example on MSDN under Process32First().
What we have done here is wrap all of the messy platform specific details into a class.

I've already seen it but it's written that it is running on Windows CE!!
When I try to compile the code from the URL the compiler doesn't know the structure PPERF_DATA_BLOCK, PPERF_OBJECT_TYPE, PPERF_INSTANCE_DEFINITION, PPERF_COUNTER_BLOCK and PPERF_COUNTER_DEFINITION. And I don't find it in the MSDN.

I'm not sure I understand your first sentence. Be careful with MSDN, there are usually two definitions when you search for something. One is for CE and one is for standard Win32. The ToolHelp API functions work under CE and 98 so you might have been looking at the CE example.
The PPERF_* structures are defined in WinPerf.h. The "PP" mean pointer to structure so if you take the first "P" off, you can see them in MSDN (look for PERF_DATA_BLOCK instead of PPERF_DATA_BLOCK).

I have been looking for "toolhelp" and there was only "toolhelp module" in the MSDN...
Now, it's working.
Thank you.

I found an "easier" way using windows hook that works both on 98 and on NT.
I create a dll to hook messages from the window and in the dll function that get the messages, i can call GetModuleFileName as the dll is maped to the process adress space  .
