Hello
I have a program written in Borland c++. It uses graphics.h to draw some rectangles and lines on console. Can this program run on MS Visual C++.
I tried it but it does not recognize graphic.h
Thank you

graphics.h is borland properitary header file... which doesn't come with visual studio... now you either have to give up dos programming or stay with borland compiler

OK i gave up dos programming...

Hi,
I'm new to Visual C++ database programing.
I'm using ODBC cursor to connect to an Access database *.mdb file.
retcode = SQLSetStmtAttr(hstmt1, SQL_ATTR_CURSOR_SCROLLABLE,SQLPOINTER)SQL_SCROLLABLE, SQL_IS_INTEGER);
I used the above line of code to make the cursor scrollable to I can do SQLFetchScroll to go backward and forward.
However I got the following error message: Optional feature not implemented.
Please help.
Thank you very much

It probably means access doesn't support scrollable cursors.

In MFC handle the WM_CTLCOLOR. Use class wizard then add code like the following:
HBRUSH CMFCDialogDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (nCtlColor == CTLCOLOR_EDIT)
{
pDC->SetTextColor(RGB(255,0,0));
}
return hbr;
}

Using Visual C++ (6.0) MFC, there is more than one way. If you search for "CEdit background", you will find 17 possible answers (see "Change the Background Color of an MFC Edit Control" ID: Q117778).
At the current time I am studying VB.Net (no choice) and in that you just call "sender.BackColor = color" ("sender" is an object derived control), which probably applies to C# as well (through the framework).
You could derive a class from a CEdit control and override the "OnEraseBkgnd" method, but there should be a better way.
That is the best I can do at the moment.

Where is the most appropriate place to save the placement of the MDI Frame window when the app is closing?
CWinApp->ExitInstance?
FrameWnd->DestroyWindow?
FrameWnd->OnCmdMsg?

I use the following so it gets stored on a per user basis...
void CMainFrame::OnClose()
{
// TODO: Add your message handler code here and/or call default
WINDOWPLACEMENT windowPlacement;
GetWindowPlacement(&windowPlacement);
AfxGetApp()->WriteProfileBinary("Settings","Window",(BYTE*)&windowPlacement,
sizeof(WINDOWPLACEMENT));
CMDIFrameWnd::OnClose();
}
BOOL CYourApp::InitInstance()
{
// Other stuff removed for clarity
// The main window has been initialized, so show and update it.
// Also get previous settings from registry for position
UINT unSize;
WINDOWPLACEMENT * pWindowPlacement;
if (GetProfileBinary("Settings","Window",(LPBYTE*)&pWindowPlacement,&unSize)) {
pMainFrame->SetWindowPlacement(pWindowPlacement);
} else {
pMainFrame->ShowWindow(SW_SHOWMAXIMIZED);
}
pMainFrame->UpdateWindow();
return TRUE;
}

I know how to change an icon, I was just wondering if anybody knows how to generate new icons at runtime, or ideally how to create a new icon identical to the previous but with different colours? Alternatively, is it possible to change display colours of an icon without creating a new one?
When I die I'd like to go peacefully in my sleep like my father, not screaming in terror like his passengers!!!

You can create a bitmap using the CreateBitmap API. Then you can use GDI to draw to it. Then you add it to the image list of the tree control using the ImageList_Add function. MFC has wrappers for there APIs.

CImageList *m_ImageTree;
TV_INSERTSTRUCT TreeItem;
HTREEITEM hTreeItem;
CBitmap bit;
m_ImageTree = new CImageList();
m_ImageTree->Create(15,15, ILC_COLORDDB,0,0);
TreeItem.hParent = TVI_ROOT;
TreeItem.hInsertAfter = TVI_LAST;
TreeItem.item.mask = TVIF_TEXT | TVIF_PARAM|TVIF_IMAGE|TVIF_SELECTEDIMAGE;
TreeItem.item.pszText = _T("TEST");
TreeItem.item.lParam = 0;
TreeItem.item.iImage=0;
TreeItem.item.iSelectedImage=0;
hTreeItem = m_Tree1.InsertItem(&TreeItem);
bit.LoadBitmap(IDB_BITMAP1);
m_ImageTree->Add(&bit,RGB(255,0,255));
m_Tree1.SetImageList(m_ImageTree, LVSIL_NORMAL);

and you can replace
HBITMAP hBmp = (HBITMAP)LoadImage(NULL,"c:\\a.bmp",
IMAGE_BITMAP,0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION);
bit.Attach(hBmp);
instead
bit.LoadBitmap(IDB_BITMAP1);

I am using DLL in one project. I built two DLLs and conresponding libs, but one dll works well and the other does not. That is one dll exports functions correctly, the other produces link error 2019. I checked the dlls by dumpbin, and found the export functions in the right dll look like "FileWrapper_Close" same as the defination of the function, but the other functions in the wrong dll look like "_CopyResamplerState@4", additional letters '@', '4' and '_' added to the name. I built the two dlls in the same way, I could not figure out why they are different. Thanks for your help.
