I solve the problem in follow way :

class CMyComboBox : public CComboBox
{
// ...
afx_msg HBRUSH CtlColor(CDC* pDC, UINT nCtlColor);
// ...
};

and

//...
ON_WM_CTLCOLOR_REFLECT()
//}}AFX_MSG_MAP
END_MESSAGE_MAP()

/////////////////////////////////////////////////////////////////////////////
// CMyComboBox message handlers

HBRUSH CMyComboBox::CtlColor(CDC* pDC, UINT nCtlColor)
{
HBRUSH hBrush = NULL;
switch(nCtlColor)
{
case CTLCOLOR_EDIT:
{
pDC->SetBkColor(RGB(255, 0, 0));
pDC->SetTextColor(RGB(255, 255, 255));
hBrush = m_brush;
}
break;
//...
}
return hBrush;
}

There is a method to get m_hWnd of dropdown list of CComboBox , of course , except GetComboBoxInfo(...) ? I need to get that handle to work on Windows NT SP6 , and there I haven't COMBOBOXINFO struct and GetComboBoxInfo ... :( I try this[^] method , but is not good for me for two reason : 1. Don't function 'nCtlColor == CTLCOLOR_LISTBOX' part , I don't know why 2. This handle will be avaiable only after I clicked to dropdown button of CComboBox , and I needed in PreSublclassWindow already . Thank you .

In fact , I try to deturn LB_FINDSTRING from dropdown list into LB_FINDSTRINGEXACT , and there must be an solution that function for Windows NT ... :(

Then perhaps you give me an alternative for this issue : I need to have ComboBoxInfo.hwndList handle for the follow function :

void CComboBoxExt::PreSubclassWindow()
{
// TODO: Add your specialized code here and/or call the base class

CComboBox::PreSubclassWindow();

COMBOBOXINFO ComboBoxInfo;
ComboBoxInfo.cbSize = sizeof(ComboBoxInfo);
GetComboBoxInfo(m\_hWnd,&ComboBoxInfo);

// m_Edit.SubclassWindow(ComboBoxInfo.hwndEdit);
m_List.SubclassWindow(ComboBoxInfo.hwndList);
SetProp(ComboBoxInfo.hwndList, WndPropertyComboBoxEx, this);
fNextListProc = (WNDPROC)SetWindowLong(ComboBoxInfo.hwndList, GWL_WNDPROC, (LONG)WinProcForList); // <- here I need ComboBoxInfo.hwndList
}

and implementation of WinProcForList is here :

LRESULT CComboBoxExt::WinProcForList(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
CComboBoxExt* pInstance = (CComboBoxExt*)GetProp(hWnd,WndPropertyComboBoxEx);
ASSERT(pInstance != NULL);

if(msg == LB\_FINDSTRING)
{
	TRACE("Replacing LB\_FINDSTRING with LB\_FINDSTRINGEXACT when looking for: \\"%s\\"\\n", (LPCTSTR)lParam);
	msg = LB\_FINDSTRINGEXACT;
}

return CallWindowProc(pInstance->fNextListProc, hWnd, msg, wParam, lParam);

}

any help or hint I will very appreciated !

Hi everyone ! Can you give an help hand , please ? I need an source code of GetComboBoxInfo function from here[^] Why ? Because I use that function in a project that I need compile on Windows NT SP6 , and there I don't have this function ... thank you very much .

I try

#include <Windows.h>

but didn't work.

Hi everyone . I try to use SetWindowLongPtr function to change behaviour of CComboBox control , but I get an error :

error C2065: 'SetWindowLongPtr' : undeclared identifier

what I can do ? I read somewhere that I need to install SDK , it's really necesary ? I mention that I use VC6 .

The problem is that when I type 'O' , the control autocompletion 'One' in editbox , select all text and put the mouse cursor at the end of the 'One' string .. is annoynig , because I want to type myself all string ... for more details , I put here[^] an source code .. .just type 'O' in combobox ....

I forget to say something : I use this , may me this cause weird behaviour ?

void CComboBoxExt::OnEditchange()
{
// TODO: Add your control notification handler code here

CString sText;
GetWindowText(sText);
if(sText.IsEmpty())ShowDropDown(FALSE);
else ShowDropDown();

}

I have an CComboBoxExt derived from CCOmboBox .. but I have an small problem , perhaps you can help me :

CComboBoxExt	m\_Combo;

void CTestComboView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
GetParentFrame()->RecalcLayout();
ResizeParentToFit();

m\_Combo.AddString("One");
m\_Combo.AddString("Two");
m\_Combo.AddString("Three");

}

and when I type 'O' in combobox , it select me automatically 'One' item from the list ... well , I try this one :

void CComboBoxExt::OnEditupdate()
{
// TODO: Add your control notification handler code here

CString sText;
GetWindowText(sText);
DWORD dwCurSel = GetEditSel();
WORD dStart = LOWORD(dwCurSel);
WORD dEnd = HIWORD(dwCurSel);
if(dStart == 0 && dEnd == sText.GetLength())
	SetEditSel(sText.GetLength(),sText.GetLength());

}

but have no effect ....

Thanks . Goes well.

I try to make an CComboBoxExt derived from CCOmboBox . In

void CComboBoxExt::OnEditchange()
{
// TODO: Add your control notification handler code here

CString sText;
GetDlgItemText(this?,sText);
ShowDropDown();

}

I try to retrive the text that user entered in combobox , and if text is not empty show drop down list , if is empty then hide drop down list .. but I stuck on GetDlgItemText method : how can I retrieve the text that user entered ? Can you help me please ? Thank you !

I found the solution , and for those hwo have the same issue , I post the code :

BOOL CMyDoc::UploadFile(CString sFileName)
{
CString sTemp;
BOOL bRet = FALSE;
CInternetSession session;
CFtpConnection* pConn = NULL;
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
sTemp = sFileName.Right(sFileName.GetLength() - sFileName.ReverseFind('\\') - 1);

try
{
	pConn = session.GetFtpConnection(\_T("ftp.domain.com"),\_T("username"),\_T("password"),INTERNET\_INVALID\_PORT\_NUMBER,TRUE);
	bRet = pConn->PutFile(sFileName,\_T("./httpdocs/temp/") + sTemp);
}
catch(CException\* pException)
{
	pException->GetErrorMessage(sTemp.GetBuffer(255),255);
	sTemp.ReleaseBuffer();
	pException->Delete();
	pFrame->SetMessageText(sTemp);
}

if(pConn)
{
	pConn->Close();
	delete pConn;
}

return bRet;

}

Maybe ( or for sure ) I don't understand something : I have an address to an server : 'http://www.testserver.com/testfolder/' and in this location ( path ) I want to upload an PC local path file : 'D:/Flaviu/test.txt' ... How can I adapt download code from above to write strings into server file ? First , create an mirror text file on server , and there write strings from PC local txt file ?

David , you are very prompt ! Thank you ! But , if I need to upload an file , don't need an login data to access upload server ?

Ok , here is my download code , which goes perfectly : ( I don't know if is corectly , but does function )

BOOL CMyDoc::GetXmlFile(CString sAddress, CString& sResult)
{
CString sTemp;
CInternetSession ISession;
CInternetFile* pIFile = NULL;
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();

try
{
	pIFile = (CInternetFile\*)ISession.OpenURL(sAddress);
	while(pIFile->ReadString(sTemp))sResult += sTemp;
	pIFile->Close();
	delete pIFile;
}
catch(CException\* pException)
{
	delete pIFile;
	pException->GetErrorMessage(sTemp.GetBuffer(255),255);
	sTemp.ReleaseBuffer();
	pFrame->SetMessageText(sTemp);
	return FALSE;
}

return TRUE;

}

I will be very glad if you can help me . Thank you very much !

I test MFC classes to download files from internet server , but how can I upload it ? Can I use the same classes / tehnique ?

Thanks , works fine ! Thank you all !!!

I don't know if is corect , but I think that I solve it :

// CMyDoc.h
typedef CTypedPtrArray CDumpArray;
class CMyDoc : public CDocument
{
protected: // create from serialization only
CMyDoc();
DECLARE_DYNCREATE(CMyDoc)

// Attributes
public:
CDumpArray m_arrDump;
...
};

// CMyDoc.cpp
CString sText = "one";
CStringArray* pTable = NULL;
pTable = new CStringArray();
pTable->Add(sText);
sText = "two";
pTable->Add(sText);

m\_arrDump.Add(pTable);

pTable = new CStringArray();
sText = "three";
pTable->Add(sText);
sText = "four";
pTable->Add(sText);

m\_arrDump.Add(pTable);

void CMyDoc::OnCloseDocument()
{
// TODO: Add your specialized code here and/or call the base class

TRACE("\\n m\_arrDump %d \\n",m\_arrDump.GetSize());

CString sTemp;
for(int n = 0;n < m\_arrDump.GetSize();++n)
{
	TRACE("\\n StringArray no %d \\n",n);
	CStringArray\* pTable = m\_arrDump.GetAt(n);
	for(int t = 0;t < pTable->GetSize();++t)
	{
		sTemp = pTable->GetAt(t);
		TRACE("\\n %s \\n",sTemp);
	}
}
int nCount = m\_arrDump.GetSize();
for(int i = 0;i < nCount;++i)delete m\_arrDump.GetAt(i);
m\_arrDump.RemoveAll();

TRACE("\\n m\_arrDump %d \\n",m\_arrDump.GetSize());

CDocument::OnCloseDocument();

}

At this code :

#if defined(DEBUG) || defined(_DEBUG)
_CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);
#endif

give me the follow error :

error C2501: '_CrtSetDbgFlag' : missing storage-class or type specifiers

Because I use VC6 ?
