The EnableWindow function enables or disables mouse and keyboard input to the specified window or control.
Are you creating the combo box and have the handle to that window
EnableWindow(hwndCombo,true); will enable the combo box

Is your purpose?
<br />
include AtlImage.h<br />
HDC hdc=CreateCompatibleDC(GetDC()->m_hDC);<br />
HBITMAP hbit=CreateCompatibleBitmap(GetDC()->m_hDC,100,100); <br />
SelectObject(hdc,hbit);<br />
FillRect(hdc,CRect(0,0,100,100), (HBRUSH)GetStockObject(WHITE_BRUSH) ); <br />
TextOut(hdc,0,0,"test",4); <br />
CImage m_Image; <br />
m_Image.Attach(hbit); <br />
m_Image.Save("D:\\test.bmp"); <br />
DeleteObject(hbit); <br />
DeleteDC(hdc);<br />

I should implement Hit Testing in a Region.

So see,a image in 800x600 and a square on thr image
<br />
CImage m_Image;<br />
m_Image.Load("d:\\0.bmp");<br />
m_Image.BitBlt(GetDC()->m_hDC,0,0,800,600,0,0);<br />
<br />
FillRect(GetDC()->m_hDC,CRect(0,0,100,100), (HBRUSH)GetStockObject(BLACK_BRUSH) );

Hi all,
I have drawn a Circle by using cdc::Ellipse(...) in a Dialog. I have a Button Control in the Dialog, when i click the button how can i erase the ellise which i have drawn with the Mouse.
I don't want to use Invaldate(..), InvalidateRect(...) for this method.
Is it possible with dc.SetRop2(...) method. if possible please provide a solution for it.
uday.

if you dont want to use Invalidate did you see CDC::RestoreDC and CDC::SaveDC
|

Hi whitsky,
Please give a snippet of code so that i can understand how to erase the Ellipse when i click the Button in a CDialog.
Please help me out.

Drawing with an XOR operation is the usual way of restoring the original bitmap - just do the same XOR draw again. Otherwise, the original draw overwrites the bits where the ellipse goes, and you have to redraw the window to remove the ellipse.

Hi
I m using RFX_Text function to retrieve the resultset from the query sp_who (back end is SQL Server 2000). But 3 columns of sp_who returns me nchar data due to which I m getting "Unicode conversion failed" error.
Please suggest me a way to deal with unicode characters.
The member variables m_strLoginame, m_strHostname and m_strDbname are declared as CString.
My sample code snippet:
void CTestdgSet::DoFieldExchange(CFieldExchange* pFX)
{
//{{AFX_FIELD_MAP(CTestdgSet)
pFX->SetFieldType(CFieldExchange::outputColumn);
RFX_Long(pFX, _T("[spid]"), m_nSpid);
RFX_Text(pFX, _T("[status]"), m_strStatus);
RFX_Text(pFX, _T("[loginame]"), m_strLoginame,500); // nchar
RFX_Text(pFX, _T("[hostname]"), m_strHostname,500); //nchar
RFX_Long(pFX, _T("[blk]"), m_nBlk);
RFX_Text(pFX, _T("[dbname]"), m_strDbname,500); //nchar
RFX_Text(pFX, _T("[cmd]"), m_strCmd);
//}}AFX_FIELD_MAP
}

Have you stepped into the RFX_Text() method to see why it is failing?

if i am working with dialog based applicatuion and want to call function like these how to use these means which class should should b include and how??
CMain* m_Main=(CMain*)GetParent();

GetParent() allows you to retrieve a handle to the specified window's parent or owner.So with this pointer that you create ,you will be able to access the data(of the public section)and the member functions of the class that are in the public section of the owner.
Suppose class A is your class from where you are calling another dialog.Then the header file for your called class should be included in A.h(Believing that this is the default header file for class A that you create.)

your problem is open a dialog or send a data?
|
|
|
|
|
my prob is opening a new window and display data coming from server.

Do you want to open an external application eg Notepad to display the text file(Use ShellExecute in this case)
If you want to show the text somewhere else you need to pass a pointer to another class from where you want to access the functions.
eg:
in wartzDlg.h include MyNewDlg.h(Supposing you name your class this way)
in MyNewDlg.h include wartzDlg.h . Create a pointer for wartzDlg in the header file MyNewDlg.h like CwartzDlg *myDlg;
Now when you call this new dialog from wartzDlg
CMyNewDlg *newDlg=new CMyNewDlg();
newDlg->myDlg=this;
newDlg->DoModal();
Now with the help of myDlg pointer you would be able to access the variables/member functions of the wartzDlg in MyNewDlg

See
<br />
WIN32_FIND_DATA find;<br />
HANDLE handle=FindFirstFile("*.bmp",&find);<br />
while(FindNextFile(handle,&find)!=0)<br />
m_List2.AddString(find.cFileName);
FindClose(handle);<br />
<br />

Since it appears that you are using MFC, check out the CFileFind class. For each file found, use CListCtrl::InsertItem() to insert the item in the list control.
