Well GHI either needs an instance of ABC or you need to make that CString a static member of ABC. However based on your last comments in the post I have doubts about your design.

Thanks. Based upon your's and Mike's reply, I am going to have rethink my design. As well as remember a little more about nested classes.

You don't have a reference to an ABC object inside GHI's constructor. m_strErrorMessageText is an instance variable, not a static variable, so you need an ABC pointer/reference/object. Nested classes are only a definition scope - you don't automatically get a GHI instance member of ABC, for example.

Mike, thanks for your excellent response. It explains things exactly and coupled with led mike's response, I'm going to have to re-design things. Not sure why the original designer used the nested classes. It seems superflous considering the original design had no members for the ABC class. Appreciate the quick explanation and help.

If you are using nested class then consider using 'friend' to control acess to members of the other classes. But you will still need a pointer/reference to access the in the first place.

I have added a List control as a resource on a dialog box. It is multicolumn and i have been able to set its column headers and width.
Now in my OnIinitDialog function i want to insert first row where the second column should have a check box instead of having any value.
Dont know how to add a check box as a item to a multilist column.
Please help me.

Use a static control with the SS_BITMAP style.

For write a title on the bottom of image on your program you can use of CDC::(Textout or DrawText) and after any effect on the image you must get a hbitmap of it and use of it on any controls.

void CNgpptDialog::ReadSerialData(CString sIn)
{
CString pressure_data;
ptrCmdResp->SetRedraw(false);
pressure_data=sIn;
int counter = ptrCmdResp->GetItemCount();
ptrCmdResp->InsertItem(counter, "");// to insert a row
ptrCmdResp->SetItemText(counter, 0, pressure_data);// column0
ptrCmdResp->EnsureVisible(counter, FALSE); // Scrolls downwords.
if(counter > 150)// I start deleting first data when the number of items in the list control is > 150
{
ptrCmdResp->DeleteItem(0);
}
ptrCmdResp->SetRedraw(true);
int nIndex = ptrCmdResp->GetItemCount();
ptrCmdResp->RedrawItems(nIndex,nIndex);
}
}
Thanks in advance

I have an VC++ application connected to database. It does the database operations such as searching records, moving to next/previous record, add, update and delete records.
Problem: When i search for records (i.e with certain condition and with sort), i will get the records on the text fields.
For example, i have retrieved 1 2 3 7 9 (using select statement in code.)
These will be stored in recordset. Suppose if i update value 9 to 4. The sort order should be maintained in text fields.. How can i get the sort order (i.e 1 2 3 4 7) without reapplying select statement?

|

use Order By in select statement.

I asked without reapplying select statement...

Hello,
Even if no process is referring to a DLL after using it for some time, can we still keep it loaded in memory? How?

no, a DLL always requires a process to be loaded into else into which memory address space would it go ?
Why would you want to do this ?

Until FreeLibrary() is called, it will remain in your process' address space.
