Really challenging ODBC problem

31-Jul-01 21:06

Hai,
I made a program to input .txt into MS Access.The text file is an output of a math program.Fine.
Now another program retrieves the data and displays it in the list control.Not fine.

The problem is the numbers displayed in the list contains an additional point other than the one already present.
When I checked in the database,it was correct ie same as that in the text file but the point gets added in the list control.Why?Whats the point?
The database fields are strings.
This problem occurs only to certain numbers in random.
I am confused.I need to use this in further calculations but it will harm my other calculations.
Help me.

And this,both the programs DONOT work simultaneously.The first was just a tool to help inputting thousands of numbers from text.

Thanx.

Hi.
I'm not about to answer your question, but to remind you, that posting the same message under different titles and more than once (I think I counted at least 10) isn't nice style. If you want to correct a message or add something,
reply on your own message thread. And if you did hit 'Submit' more than once, because it seemed like the server hang, delete the message posted additionally.

Query builder component

for my application i need to develop a component which allows the user to select the table,fields inside the table and based on his selection a sql query needs to be build. This is similar to the query builder in ms-access. Is there any component available for the above purpose or is it possible through some com interfaces.Any pointers, references i can get is most welcome.

thanks in advance.

Cheers
kannan

we built our own that shows as a dialog box with fields specific to the app we develop that allows users to select various groups of items to filter views by and buils a sql statement based on that

i was going to try and generalize it and post it here but i have no time at the moment what with work committments and all but i will get around to it asap

as for any components that i know of ... unfortunately not ... there are some that you have to pay for ... try posting on the database newsgroups for more details

sorry i cant be more help

The control does not contain enough information for you to reuse it. I'd suggest this is by design.

I've been looking through the examples her at Code Project, but I can't see one that shows me how to create a button or a test edit window entirely in code (i.e. not on the dialog template).

Can someone help me out here ?

OK - got that working like this:

RECT rc = {10, 10, 50, 50};
m_btn.Create(m_hWnd, rc, "", WS_CHILD | WS_VISIBLE);
m_btn.ShowWindow(SW_SHOW);

I actually didn't notice that I was creating a button on screen in the corner - why isn't WS_CHILD a default value ?

Anyhow, now I need to know how to get messages from the button in my dialog. From memory it's subclass window, is that right ?

I'm editing this message now - it's not SubclassWindow, which allows me to attach a variable to a control on the dialog. I want to create a CButton and capture it's being pressed ( actually I want to be able to do that to lots of them ). Can anyone suggest how this is done ?\

Editing yet again. I discovered if I overrode WM_COMMAND I could catch the button press, with lParam equalling the hWnd of the button. I've used this prototype:

LRESULT OnCommand(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& /*bHandled*/)

and found that wParam is always 0 and uMsg is 0x0111 ( WM_COMMAND ). Surely WM_COMMAND will be called for things other than buttons ? How can I tell how I got there so I can respond intelligently to the event ?

Thanks

I tried to do like you did:

RECT rc = {10, 10, 50, 50};
m_btn.Create(m_hWnd, rc, "", WS_CHILD | WS_VISIBLE);
m_btn.ShowWindow(SW_SHOW);

But I'm using a CView class to display the button, not a CDialog. Is that a problem?

If I want a button to be visible "on" a CView client area, where would I call m_btn.ShowWindow(SW_SHOW)?

Thx,

I'm not sure how ( or why ) you'd put a button onto a normal CView.

I am actually using the Windows Template Library, but to put buttons onto a CView in MFC, you can use a CFormView, which allows you to set them up using a dialog template.

Um... not quite. There you (very helpfully) showed me how to hook up buttons and so on into a message map. Now I want to create them dynamically, not by putting them on a dialog template and calling SubclassWindow, but by having a vector of controls to which I can dynamically add them, and have the code able to respond to their being pushed. The idea is that we create a set of classes by which people can script the creation of a dialog box and it's controls, so it needs to be ultra flexible.

I've worked out that I can respond to OnCommand, and the lParam ( from memory, the code is at work and I am not ) is the HWND of the control, but none of the other paramters seen to contain anything meaningful. Is this the way to capture buttons I've created on the fly, and if so, does OnCommand respond to anything but controls being pushed ? Either way, when I have a lot of different elements on the dialog, I'm not sure how I'm going to be able to figure out what was interacted with and how, in order to respond to it meaningfully. The Create method didn't seem to take an ID I could assign, for example, and I'm trying not to think about intercepting messages on a dynamically created listview, for example.

Any suggestions you may have on how to deal with a variable number of controls on a dialog that will not be known until runtime will be greatly appreciated.

Ah, gotcha, I see what you're asking now. Smile | :)

Here's a snippet that creates a button at runtime. This came from the CP toolbar, actually, and creates an edit box on the toolbar.

  // m_wndToolbar is a CContainedWindow<ATLControls::CToolBarCtrl>
  // m_wndSearchEdit is a CContainedWindowT<ATLControls::CEdit>
 
    m_wndToolbar.GetItemRect ( 1, &rect );
 
DWORD dwEditStyle = WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER | ES_AUTOHSCROLL;
DWORD dwEditExStyle = WS_EX_CLIENTEDGE;
HWND hwndEditbox = CreateWindowEx ( dwEditExStyle,  _T("EDIT"), _T(""), dwEditStyle,
                                    rect.left+5, rect.top, rect.right - rect.left-10,
                                    rect.bottom - rect.top, m_wndToolbar,
                                    (HMENU) uSearchEditboxID, NULL, 0 );
 
    m_wndSearchEdit.Attach ( hwndEditbox );

This uses member variables for the windows (CContainWindow objects) but this would work equally well for objects you create at runtime.

As for your WM_COMMAND question - lParam is the HWND of the button, HIWORD(wParam) is BN_CLICKED (which is 0), and LOWORD(wParam) is the button control ID. If wParam is coming in as 0, I'd say double-check the control IDs in your CreateWindow() or analogous calls.
