how can i speed my database and fill in my CListCTtrl ?
because i need all the data in my CListCtrl i can t use a virtual list ok !
it is simple i need all the data in my Clistctrl at once !
for now i fill 60 000 records in my CListCtrl in 1 min. and i need more speed because i want to fill more data and i will have more time to load and i don t want this i need more speed !
- for my database
- for my CListCtrl
Database = VisualFoxPro 6.0 .
for now this is my code :
void CNcontabile::FillList()
{
CDatabase_Plan* pPlan = new CDatabase_Plan();
if (!pPlan->Open())
return;
if (pPlan->IsOpen())
{
pPlan->SetRowsetSize(25);
while (!pPlan->IsEOF() )
{
int nRowsFetched = pPlan->GetRowsFetched();
m_list.InsertItem(nRowsFetched, pPlan->m_name);
m_list.SetItemText(nRowsFetched, 1, pPlan->m_city);
pPlan->Move(SQL_FETCH_NEXT);
pPlan->MoveNext();
}
}
//m_list.UnlockWindowUpdate();
m_list.Invalidate();
m_list.UpdateWindow();
pPlan->Close();
delete pPlan;
}
if you have an ideea on how can i get more speed please tell me !
i will wait your answer !
Thank you !

Hi Flaviu_2006,
You have 60,000 records in your database but i dont think you need to all records at a time you said you cant use of virtual list so i think its a good idea you show each 250 or 500 records at each the moment and also i search and i see you can see a lot of explains on the internet for speed up your database did you seach about it

Why? I don't recall ever having the need to operate on such information en masse.

Why? Do you simply not know how, or do you know for certain that it cannot be used?

Hi guys!
I'm begginer thus I'm really appreciate if you concern my question.
I got two dialog. The first one is Dlg1, the other is Dlg2.
There is a variable which calls root in Dlg1. It was declared when the Dlg1 was first appreared.
There is a variable which calls temp in Dlg2.
The problem is, I cant do:
temp=root;
Thanks for reading my question
hehe

What's the type of the variable? Is it the object of the class.

What's root?

???
If you can better explain your query or post some code some one here would help you in a better manner.

typedef struct point
{
CString code;
CString name;
float previous;
float present;
point *next;
} pointer;
pointer *root = new pointer;
I want temp in Dlg2 has the same type and data as root!
thanks for concerning my question

You can pass a pointer from Dlg1 to Dlg2 and then access the variables of root directly in Dlg2.

I do have that kind of idea in mind but the problem is how to do so!

Create a pointer variable for Dlg1 in Dlg2.h. Also #include "Dlg1.h"
Say Dlg1 *pDlg1; // This is to be done in Dlg2.h
Add #include "Dlg2.h" in Dlg1.h
Now when you are giving a call to Dlg2 you can write
Dlg2 *p2=new Dlg2;
p2->pDlg1=this;
p2->DoModal();
Then you would be able to access the variables for root from Dlg2.

Dlg2 *p2=new Dlg2;
p2->pDlg1=this;
p2->DoModal();
I tried to put these code in Dlg1. Everything seems to be fine but the only line:
p2->pDlg1=this;
with the error message: "pDlg1 is not a member of Dlg2"
What should I do?
Thanks for concerning my question

Probably you are missing to include a file some where. Either in Dlg1 or in Dlg2.
Check it out....

in PointerAppDlg dialog:
#include "stdafx.h"
#include "PointerApp.h"
#include "PointerAppDlg.h"
#include "Search.h"
typedef struct point
{
CString code;
CString name;
float previous;
float present;
point *next;
} pointer;
extern pointer *root = new pointer;
but in Search dialog:
it failed at
#include "stdafx.h"
#include "PointerApp.h"
#include "PointerAppDlg.h"
#include "Search.h"
pointer *root;
Thanks for concerning my question!

return hbr;

Try this for the edit box. I think I answered the same question yesterday. Didn't this solve your problem.

Does no vtables depends on no of objects of the Virtualclass ?
|
|
|
|
|
|
The number of vtables created are one for the base class and one for each of the subsequent classes that are derived from the base class.
Suppose Base and Derived are two classes. Class Derived is derived from Base.
then there would be two virtual tables that would be created. It does not depend on the number of objects.

that means can i assume that Virtual base class Contains one Vtable, And the Entire hierarchy contains one VTable.
Totally two VTables
|
|
|
|
|
No!
Each of the classes that are derived from the base class would have a vtable of their own
Suppose Base, Derived1, Derived2 would be the three classes. Derived1 and Derived2 are classes that are derived from the base class. Now in this case there would be 3 vtables. One for base. One for Derived1 and one for Derived2.
