Hi,
I like a lot of having this: Data Layer / Bussiness Layer / and GUI Layer... for a web based project I understand how it works but....
What about a Desktop approach... this case: I need to show in a DB Grid, a query or table, that can have 5, or 5000 thousand elements, how can I do this in a Layered approach ?
Should I make a control that gives me the number of elements, and pages of b.g. 50 rows..., and Have one special control that will show the 50 and simulate the scroll for 5000 thousand ?, Is that already done somewhere ?
Or should I pass a Recordset as a parameters from the ActiveX control to the App ( then what about the open Database Connections... ?).
Thanks in advance, Greetings

From within an event handler in an SDI main frame class, how do I get a pointer to a modal dialog box or property sheet where pointer->IsKindOf will return the dialog box / property sheet class?
I have tried
CWnd * pForeWin = GetWindow(GW_HWNDNEXT);
if (pForeWin->IsKindOf(RUNTIME_CLASS(CMyPropertySheet)))
{
But GetWindow returns a pointer to a CtempWnd.
Thanks in advance

The compiler information me that  :\microsoft visual studio\msdev98\myprojects\newprint\cprinter.h(71) : error C2011: 'CPrinter' : 'class' type redefinition
Why did the error appear?
|
|
|
|

MSDN:
Compiler Error C2011
'identifier' : 'type' type redefinition
The specified identifier was already defined as type type.
The following is an example of this error:
struct S;
union S; // error

It could be a number of reasons. One of the most usual is that you forgot to insert safeguards against multiple inclusion:
#ifndef CPRINTER_H
#define CPRINTER_H
#endif

Hello,
I am learning socket programming in windows right now, however, I have some problems with the second parameter when I using this function: listen(socket, int). I don't understand what the second parameter for and how to use it. Thanks for someone to help!

MSDN :
int listen (
SOCKET s,
int backlog
);
backlog
[in] The maximum length of the queue of pending connections. If this value is SOMAXCONN, then the underlying service provider responsible for socket s will set the backlog to a maximum "reasonable" value. There is no standard provision to find out the actual backlog value.
So its the number of pending connection on the server side, cos a listening socket is on server side!
its up to u to know how manny u need in the queue waiting to be served by the server!

I am sorry, what do you mean pending connection? Would you mind to give me an example, let say Iset the blacklog to 3, what will happen? Thanks!

Pending means waiting inthe queue on server side,
let say Iset the blacklog to 3, what will happen?
A maximum of 3 will stay in the queue untill they are served!
U can accept a conection with the accept function

I have an Edit control for hex input, and I'd like draw it with spaces between every two characters (the user doesn't actually type any spaces):
43 4F 44 45 50 52 4F 4A ... etc
I'd rather not use SetWindowText to shove the spaces directly into the text, since I'd have to have special handling for editing, cutting, pasting, undo, validate and all.
Is it possible to do the formatting at display time instead? I looked through the MFC source and I didn't see any CEdit draw methods that I could override.
|
|
|
|
|
Look in the CEdit section here, there are several masked edit classes if memory serves.
|
|
|
|
|
The masked edit classes keep the literals within the data, and so they have to have special processing for all edit and cursor functions. I could adapt one of these useful classes to insert that space every two characters, but it seems like overkill. 
I'd like to keep the text data the way the user enters it, and mess only with how it would get displayed. My idea is to grab the draw method for CEdit and override it with a function that formats a copy of the text right there, and displays it. I like minimal added logic.
Problem is, I don't have any idea where the CEdit control is drawing itself. I looked in the MFC sources and I can't find anything like CEdit::OnPaint(). Can anyone offer any clues on this?
|
|
|
|
|
Mabe you can handle EN_UPDATE and reset the text in the control to have every third letter a blank?
|
|
|
|
|
That's an idea I can try. Not as clean as I hoped, but if it does the job, I'll use it.

Hello fellas
Which GDI+ class lets you open a bmp file and draw it on your CView derived class? And will it take care of painting or do we have to keep re-rendering it in the OnDraw?
Regards,
Nish
p.s. I went through the GDI/GDI+ sections on CP. Haven't been able to find what I wanted

Ha! Straight from MSDN:
Image image(L"Grapes.jpg");
graphics.DrawImage(&image, 60, 10);
Go and do likewise...

Ok, more browsing through MSDN - try skipping the whole "new" thing, & using Bitmap::FromFile() to produce the Bitmap*.
