I'm trying to send a message from my ListBox custom class to another class which utilizes the control. In the Listbox control I build a LV_DISPINFO struct and then pass it to a SendMessage method to be used by the OnNotify message in the calling class. In this example CCreateWorldStep1Dlg uses the ListBox custom control whereas the ListBox custom control passes a message back to CCreateWorldStep1Dlg as a Notify message.
<br />
void CCreateWorldStep1Dlg::OnNotify(UINT message, LPARAM lParam) <br />
{<br />
CString Buffer;<br />
LV_DISPINFO *pInfo = (LV_DISPINFO *)lParam;<br />
<br />
pListBox->GetText(pListBox->GetCurSel(), Buffer);<br />
if(pListBox->GetCurSel() == pListBox->GetCount() - 1)<br />
pRegionsArray->Add(Buffer);<br />
else<br />
pRegionsArray->SetAt(pListBox->GetCurSel(), Buffer);<br />
}<br />
The problem is that variable pInfo contains garbage when I look at it. May I be converting the lParam incorrectly?
This is how I am sending the message
GetParent()->GetParent()->SendMessage(WM_NOTIFY, m_DlgID, (LPARAM)&dispinfo);<br />
Thanks for the help

Hello,
I have a smiple dialog box with a edit control(multiple line).. I pump strings into the edit control and start filling it up.. each string I put into the control goes on a new line below the previous line.. How do I get the control to auto-scroll down so that each new line that is inserted is displayed with out having to manually scroll to the bottom of the control.
Thanks!

Try with m_youredit.SetSel(-1,-1,TRUE).

 Didn't work.. I have tried even tried SetScrollPos(SB_VERT,1,TRUE); to scroll the bar down only one click.. but it doesn't seem like anything is effecting the scroll bar.

hadi,
I understand that you can set the readonly feature in the connection string.
"Provider=Microsoft.Jet.OLEDB.4.0;Password="""";User ID=Admin;Data Source=C:\test.mdb;Mode=Read;Extended Properties="""";Jet OLEDB:System database="""";Jet OLEDB:Registry Path="""";Jet OLEDB:Database Password="""";Jet OLEDB:Engine Type=4;Jet OLEDB:Database Locking Mode=0;Jet OLEDB:Global Partial Bulk Ops=2;Jet OLEDB:Global Bulk Transactions=1;Jet OLEDB:New Database Password="""";Jet OLEDB:Create System Database=False;Jet OLEDB:Encrypt Database=False;Jet OLEDB:Don't Copy Locale on Compact=False;Jet OLEDB:Compact Without Replica Repair=False;Jet OLEDB:SFP=False";

Hello Alex
Thanks for reply, i'll test it and then tell you the result ...
About the connection string ...
I don't most of connection string parameters that you wrote 
for example:
Extended Properties, Jet OLEDB:System database, Registry Path and etc ...
Could you explain about connection string parameters ?
I have other question, too.
I have problem in opening database from CD !!!
Because as you know, when i open the access database, the access database makes a .LDB file beside the access database !
So can you tell me, how can i open access database from CD ?
Is opening access database as read-only good way ?
Regards,

The parameters are those generated from C# when addition a OleDBConnection object to a form.
I am sure I succeeded in reading an Access database from a CD in the past. However, performance is not good.
Cheers,
Alex

I have an MDI app, CMyEditDoc (from CDocument), and CMyEditView (from CEditView).
In CMyEditDoc, I have a CStringArray with text I want displayed.
How do I actually get the view updated from the doc?
I seem to have a block in understanding this. Can someone help a brother out, here?

the usual way is to call CMyDoc::UpdateAllViews. this function takes a couple of parameters that you can use to use to pass a flag or a CObject-dervied class (or actually, anything because you can cast to a CObject* to pass and then cast back to the real type in the view).
anyway, you call UpdateAllViews with your flags/data and then in your view's OnUpdate handler, you look at the parameters that were passed and act accordingly.
most of my apps will just send a flag in UpdateAllViews. the views look at that flag, decide what to do and call back to the doc to get any data they need. i rarely pass much data in the CObject* parameter (sometimes i pass a little bit of state info, but rarely do i pass the real document data).

Hello Everybody:
I want to have a group box that becomes visible and invisible by clicking another object (it could be a button or even an Bitmap with WM_LBUTTONDOWN maybe). Is there a way that I can do this? If so, can you give me a quick example?
Regards,
Luis E. Cuadrado

The thing seems simple. Where are you stuck? Showing/hiding a control (or any window) can be achieved with ShowWindow.

Thanks for the quick reply. Well, I'm stuck in showing and hiding the control itself. I'm not sure if a group box is considered a CStatic class, or a CButton class. But what I'm planning to do is in a Dialog, to have a Button or a Bitmap control and when I click that control the group box will appear.
If you need more info, let me know.
Gracias,
Luis E.

Insert the group box into your dialog resource. Then, anywhere inside the dialog code, GetDlgItem(IDC_YOUR_GROUP_BOX) (or whatever identifier the box has) will give you a CWnd * on which you can call ShowWindow.

Just to make sure. Are you aware that showing and hiding a group box will not show or hide the controls in that box?

Hi all,
Is TAPI 2 capable of dialing digits on a line while a call is in progress, i.e. to respond to voice mail options?
Thanks!

Yes, use lineGenerateDigits()

Can VS7 optimize compilation for a dual-processor machine?
I have a dual-processor machine here, and I have some analysis code that completely peaks out performance - but between the 2 processors, it's only 50% system performance.
Now I'm an assembly programmer, so I don't mind doing some low-level coding to hand-optimize it, but I have this horrible feeling that WinNT is going to shout at me if I try to take it over.
Any thoughts? Do I need a new compiler?

Just from the top of my head.
If you have only one thread, I think a second processor is useless. Having multiple processors is usefull only for multi-threaded apps or when running multiple processes.

I'm not 100% sure, but I'd say Windows OSs do not distribute a given process execution among different processors --they only assign processes across processors to balance the load. So to take advantage of a 2-CPU machine in a single program, you should be launching processes from the app, much the same ay as you would with threads.

Hmmm. This is my understanding as well... So it's going to be a major pain in the ass to share the data between processes.

It is not that hard. Use shared data segments for accessing and named mutexes for synchronization.
