What does 'not working' mean ? This is full of MFC calls, without knowing what the objects are, it's very hard to comment. Even harder when we don't know what's going wrong.

CDatabase_Mydatabase *pBun = new CDatabase_Mydatabase;
CRecordset !!!!
its call from my CDialog !
where i have 1 CEdit and 1 CListCtrl ;
Bravoone

Why this:
pBun->Move(AFX_MOVE_REFRESH);
Have you stepped through in debugger?
Is sTemp valid before copying it to the field variable?
Any exceptions thrown from database classes?
Is the recordset cursor on a valid record when you call Edit()?
What is happening or not happening that makes you think it's not working?
|
|
|
|
|
yes is on Cur record but no changes on record field after i finish!
lets say forget about pBun->Move...
its still not working no exceptions , no errors,nothing but my records are the same !

i have an error from my database :
SQL statement too long ! what is that ?

There is nobody who can help me , please !!!!!!!!!!!

hey, can't you wait a little ???
most people here are either t work, or still sleeping, so wait at least one day to be sure that nobody can answer.
since then, ask yourself WHY people didn't answer your question. it can be because no one is able to, but also because the question is badly formulated...
in any case, wait dude !! 2 hours is really a too small time span for a forum

ok !
i have another question !
what is that mean ?
SGL : Statement too long !
this is what i have when i access the database !
this is my code :
CDatabase_Mydatabase pBun;
...............................
//this i found the field
//now all i wanth is to replace a field from my database with sTemp + the field !
pBun.Edit();
m_city.GetWindowText(sTemp);
pBun.m_rcd12.Replace(pBun.m_rcd12,pBun.m_rcd12 + sTemp);
pBun.Update();
pBun.MoveNext();
pBun.Close();
but is not working i have this error:
SQL : Statement too long;

You shouldn't be calling Edit()/Update on a CDatabase object. Should be a CRecordset.
You haven't shown yet perhaps the most important part - the query (and/or recordset open).
I'll try and help as fast as I can but I had to sleep 
|
|
|
|
|
The database is open and after that close.
but what is wrong ?
i have this message: "SQL : statement too long"
Bravoone
|
|
|
|

Sounds like the SQL statement is too long.
You still haven't posted any code that would either work properly or show the problem so
that's the best guess I have.
The database is open, ok. What about the recordset?

Hi
I have CMyComboBox derived from CComboBox.
Using it in CMyFormView in VC++6/MFC/Win98/2K project.
In my invoice form, I need to have multiple combos with 40000+ products.
Virtual list for combo can make it possible. (multi column virtual list for combobox)
What I am trying to achieve is :
- show dynamically created CListCtrl* m_pMyListCtrl (with LVS_OWNERDATA) instead of default ListBox of CMyComboBox
- that CListCtrl in virtual mode should get data from CMyFormView
- same member of CMyFormView (CArray of products) used to show data in virtual list (m_pMyListCtrl)
Problem is how to pass-on LVN_GETDISPINFO message from m_pMyListCtrl to CMyFormView so as to get item info (m_pMyListCtrl is dynamically created virtual list control - member of CMyComboBox).
I truly appreciate any idea or help.
Thanks
Anand

overide the WindowProc() of the formview inside it check
1. message is WM_NOTIFY
2. if so check wParam is LVN_GETDISPINFO
3. if so cast the lparam to LPNMLVDISPINFO

Thank you for helping.
In fact, I am trying to use list of following multi-column combo control in virtual mode.
Multi column Combo box (2) (CodeGuru Article)
http://www.codeguru.com/cpp/controls/combobox/multicolumncombos/article.php/c1819/
What I tried is:
1. Added LVS_OWNERDATA style to defaultListControlStyle
2. Added my new view (CFormView)
3. Added custom control in view and subclassed (as suggested in article) for Multi column Combo
Still I am unable to pass-on LVS_GETDISPINFO to my form view.
(i.e. I could use list of this combo in normal mode in my form
but unable to use it in virtual mode)
Please help...(Urgent help needed).

Naveen, Thanks a lot for helping.
What I tried is:
1. Downloaded sample from following article and unzipped
Multi column Combo box (2) (CodeGuru Article)
http://www.codeguru.com/cpp/controls/combobox/multicolumncombos/article.php/c1819/
2. Removed code which displays Multi-column Combo in toolbar (from Mainframe.h and Mainframe.cpp) as I don't need that
3. Added LVS_OWNERDATA style to defaultListControlStyle
4. Created new dialog resource (Set style to Child and Border None), and
added custome control IDC_CUSTOM1 (class MultiColumnComboBox)
5. Created new view class CMyTestView (derived from CFormView)
5. Added protected member to CMyTestView ->> CMultiColumnComboBox m_combo;
6.
void CMyTestView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
// subclassed custom control (as suggested in article)
m_combo.SubclassDlgItem(IDC_CUSTOM1);
// add columns to list
// do not insert items in list (as it is virtual)
CListCtrl* pList = m_combo.GetListCtrl();
pList->InsertColumn(0, _T("Col 1"), LVCFMT_LEFT, 100);
pList->InsertColumn(1, _T("Col 2"), LVCFMT_LEFT, 100);
}
8. To make view class as parent of list control,
In CMultiColumnComboBox::OnInit() (where ListControl is created)
I replaced following line
// if( m_pListCtrl->Create(WS_BORDER|WS_CHILD|defaultListControlStyle, Crect(0,0,0,0), GetDeskTopwindow(), IDLISTCTRL) )
with
if( m_pListCtrl->Create(WS_BORDER|WS_CHILD|defaultListControlStyle, Crect(0,0,0,0), this->GetParent(), IDLISTCTRL) )
7. Then tried as you suggested in CMyTestView.
In view, I am getting LVN_GETDISPINFO notification
I am setting item text
but list is not getting even single item
I am unable to get data through LVS_GETDISPINFO to list of combo in form view.
(i.e. I could use list of this combo in normal mode in my form
but unable to get data from view in list of combo in virtual list mode)
Please help...(Urgent help needed).
I truly appreciate any idea/help.

can u show me the code u used in the CMyTestView for getting the LVN_GETDISPINFO notifications and setting the text..?
Also i hope u have inserted two columns in the list ctrl...
nave

|
|
|
|
pls asure CListCtrl::SetItemCountEx() has been called with proper value
nave
|
|

Thanks Naveen for taking me into right direction.
I did forget to set count for list with SetItemCountEx()
I did it and now I am able to show 100000+ items in the virtual list of CMultiColumnComboBox.
Thanks a lot for helping me.
One Question..?
I have custom control IDC_CUSTOM1 in dialog resource of my view.
I have subclassed IDC_CUSTOM1 to CMultiColumnComboBox
In my project value for IDC_CUSTOM1 is 1005
In MultiColumnComboBox.h value for IDLISTCTRL is 0x3E8 (i.e. 1000)
View gets LVN_GETDISPINFO message directly from IDLISTCTRL
(i.e. with control-id == IDLISTCTRL)
But I need LVN_GETDISPINFO with id of custom control IDC_CUSTOM1
(i.e. with control-id == IDC_CUSTOM1)
How to modify CMultiColumnComboBox::ParentWndProc or MultiColumnComboBox::ListCtrlWndProc so that I get LVN_GETDISPINFO with ID of parent custom control and not of ListCtrl ?
So I can distinguish LVN_GETDISPINFO message in case of multiple combos. Because I need to use multiple combos IDC_CUSTOM1 , IDC_CUSTOM2, IDC_CUSTOM3 etc. and each of them in virtual mode.
Thank You.

i think thats not possible. but there is turn around
I hope u use a listctrl derived class object as virtual list(if not so, derive a class from clistctrl and use bject of that class as virault list )
Add a member variables in that class say m_nParentComboId;
After u create the listctrl for a combo, set the correponding combos id into listctrl member variable(m_nParentComboId).
So when ever u get a LVN_GET... message. check the m_nParentComboId to find which combox is associated with the list ctrl

Nice idea to add m_nParentComboId for parent combo identification. I may do that.
But One thing...
In CMultiColumnComboBox::OnInit(), after creating list control, with ::SetWindowLong statement... it stores pointer to CMultiColumnComboBox as a long.
::SetWindowLong( m_pListCtrl->m_hWnd, GWL_USERDATA, long(this) );
(Whenever LVN_GETDISPINFO message comes in view from list ctrl)
Can I get that value and use that value to identify control id or parent combo ?
Thanks for all your help. I learnt nice tricks for handling virtual list.
