Hi I have a problem
When I call this function below, I get this error:
"Too few parameters. Expected 1."
What am I doing wrong here?
Here is the function:
void CMyTreeView::FillProducts()
{
CProductSet *pSet = &(GetDocument()->m_productSet);
pSet->m_strFilter = "[Categories].[CategoryID] = [Products].[CategoryID]";
if (pSet->IsOpen())
{
pSet->Close();
}
pSet->Open();
if (pSet->IsBOF())
return;
pSet->MoveFirst();
while (!pSet->IsEOF())
{
HTREEITEM hProductNode = FindNode(NULL, pSet->m_CategoryName);
InsertNode(pSet->m_ProductName, hProductNode);
pSet->MoveNext();
}
}
Here is the CProductSet:
void CProductSet::DoFieldExchange(CFieldExchange* pFX)
{
//{{AFX_FIELD_MAP(CProductSet)
pFX->SetFieldType(CFieldExchange::outputColumn);
RFX_Long(pFX, _T("[Categories].[CategoryID]"), m_CategoryID);
RFX_Text(pFX, _T("[CategoryName]"), m_CategoryName);
RFX_Long(pFX, _T("[ProductID]"), m_ProductID);
RFX_Text(pFX, _T("[ProductName]"), m_ProductName);
RFX_Text(pFX, _T("[ProductDescription]"), m_ProductDescription);
RFX_Long(pFX, _T("[Products].[CategoryID]"), m_CategoryID2);
RFX_Text(pFX, _T("[SerialNumber]"), m_SerialNumber);
RFX_Text(pFX, _T("[UnitSellingPrice]"), m_UnitSellingPrice);
RFX_Text(pFX, _T("[UnitCostPrice]"), m_UnitCostPrice);
RFX_Long(pFX, _T("[ReorderLevel]"), m_ReorderLevel);
RFX_Long(pFX, _T("[UnitsInStock]"), m_UnitsInStock);
RFX_Long(pFX, _T("[SupplierID]"), m_SupplierID);
//}}AFX_FIELD_MAP
pFX->SetFieldType(CFieldExchange::param);
RFX_Text(pFX, "ProductNameParam", m_ProductNameparam);
}

Your code doesn't match your table design. I suspect that one of the fields you have coded to read from doesn't exist in your table definition.

The first time a programmer logs into our network they download any software updates made the previous day by the other programmers. Now I have moved from a desktop to a notebook I need to be able to run the same download program when my machine comes out of hibernation. I currently have to log off and log back on again each day which is annoying. Any information you can provide would be greatly appreciated.

I am writing a class to display a grid in a view. This is not a database grid, but a grid that graphically illutrates which elements of a 35 element laser beam have been triggered over time.
So the width of the grid is 35 elements wide (constant) but the height is variable over time. I need to store the data to represent the state of each block within the grid (triggered = display grid element in blue OR not triggered = display grid element in gray for instance).
My plan is to store the the 35 element grid row in a:
vector<bool> Grid_Row;
since the size is predetermined, and store the collection of vectors in a deque:
deque < vector<bool> > Grid_Deque;
This works fine as it stands, but now I have to attach a time indicator to each row. My first plan was to convert the deque of vectors to a deque of structs (which would contain the vector and a timing variable:
struct GridRow
{
UINT time;
vector <bool> gridRow;
};
GridRow gr;
deque < gr > Grid_Deque;
Unfortunately this is not working to well.
Can someone help with this. Maybe tell me how to get this working(if it is possible) or maybe suggest a better solution.
Thanks
-Merle

deque < gr > Grid_Deque; Maybe I'm totally obfuscated, but ain't this to be
deque < GridRow > Grid_Deque; ?

The code doesn't compile? Monitor explodes when program runs? Something else?

Will not compile, too many erros to mention.

Post your declarations using 'no HTML' option. Without that, the > and < are missing.

If it were me, I would typedef the things I wanted to use as such
typedef vector <bool> GridVect;
typedef struct tagGridRow
{
UINT time;
GridVect gv;
} GridRow, *pGridRow;
typedef deque <gridrow> GridRowList;
and then instantiate these objects as you need them.
i.e.
GridRow gr;
GridRowList grl;
grl.push_front(gr);
In your first code, I do not see where you declare what you are putting in your vector.

I want to implement a control in my app similar to the Workspace in Visual Studio. In the Workspace, although your project (source files etc) are presented in a tree, you can select more than 1 node at a time. I don't think I can base my control on the TreeView control since it doesn't support multi-select. Any ideas? Thanks in advance. DEM.

Oct'96 issue of MSJ, C++ QA column by Paul DiLascia contains the code you need. The article may be in the MSDN installed on your disk. If it's not there, go to msdn.microsoft.com and search for CMultiTreeCtrl.

Hi.
I have programmed a Dialog box with a progress bar.
But I want the progress bar to run a soon as the dialog opens with no prompt from the user, how do i do this. InitDialog is too early if you get my drift.
I am using VC++ 6.0
Regards
Mark

How are you going to increment the progress bar value? Is it related to some background task?

It is surprising to me that you consider OnInitDialog too early to initiate your progress bar. This handler is on the very brink of the moment when the dialog is shown up!
Anyway you can handle WM_WINDOWPOSCHANGED, which is (if I'm not wrong) the very first message sent right after the dialog appears on the screen.

Put a timer in the Dialog box. Start it in the OnInitDialog....
In the OnTimer, Test if the Dialog is Visible and Ready....

There are two ways to write error-free programs; only the third one works.

I'm still fairly new to VC++
So do I create a member for a timer, is it a CTimer??
What function(s) do I need in my cpp??
Mark

Yes you need to Use the CWnd::SetTimer function and add the message CWnd::OnTimer

Beta. Software undergoes beta testing shortly before it's released. Beta is Latin for "still doesn't work."

Its actually greek if I'm not mistaken. Nice joke anyway.
.NET or not .NET? MFC is the question......

You should be able to access any control in a dialog box from the OnInitDialog method. All controls have been created at this point. UNLESS you have subclassed any of the controls (i.e. you created member variables for them with Class Wizard). They do not get connected until the first call to DoDataExchange. But this gets called by CDialog::OnInitDialog(). Use the code snippet below as a reference:
BOOL CCreateReportDlg::OnInitDialog()
{
CDialog::OnInitDialog();
}Hope this helps.

For modeless dialogs, subclassed controls get created after your overridden OnInitDialog() has finished executing.
When I want to initialize subclassed controls in a modeless dialog, I post a custom WM_COMMAND (like IDC_INIT_GUI) from OnInitDialog() and handle the initialization in the handler OnInitGui().

If you are manually subclassing controls then it is completely up to the programer to determine when to subclass and init controls. But if they are done through the Class Wizard they can be accessed from the OnInitDialog method after the base class call CDialog::OnInitDialog for modal or modeless dialogs. Here is some currently working code that works as modal or modeless.
void CMyDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_PROG_BAR, m_progBar);
}
BOOL CMyDlg::OnInitDialog()
{
CDialog::OnInitDialog();
m_progBar.ShowWindow(SW_HIDE);
CenterWindow();
return TRUE;
}This code works fine if you are displaying your dialogs the normal way.
CMyDlg dlg;
dlg.DoModal(); or
CMyDlg *pdlg = new CMyDlg;
pDlg->Create(IDD, pParent); No need to do any custom messages if they are not needed.
Of course, from the original message it hard to know what the author means by “I want the progress bar to run a soon as the dialog opens.” Writing code to updated a progress bar is a whole other discussion.
