no, it wasn't that simple... I did run into same problem sometimes

The best way is to get a new object via new.
Everything else makes your application crashing after some time.
i've tried many solutions but that one is the best, but you have to care about deleting at the right time.

Could you explain this problem a little more detailed? I use dynamic and static socket objects, my app runs stable... well, I think it does.
Thanks, Moak

Anybody can give me a sample code of IE horizontal band (at the bottom of IE)?
|
|
|
|
|
I dont know but the only thing I see at the bottom of IE is a standard statusbar. (IE 5.5 so maybe there is another bar in newer versions)
But the top Bar is a CReBar in case you're wondering.
I used to have a life ... now I have a computer

yeah..the bar is so common...but what do you exactly mean?

Hi i've just started learning c++ with visual c++.net standard, after programming in java for about 3 years.
Im trying to build a simple QT example, copyed and pasted from there site. but im getting heaps of errors from qstring, qapplication,...
I have set the project director setting with the qt/lib, /include, /bin directorys.
This has to be a simple problem.
Any advice?
thanks.

This is the most simple example i wanted to start off with.
I created a new win32 project, the other project files are blank ( resources.h ,QT2.h )
Is it the way im creating the project?
The QT .lib,.h file paths are added to the project settings.
Is there a particular order they should be in?
Thanks for any help!
// QT2.cpp
#include "stdafx.h"
#include "QT2.h"
#include <qapplication.h>
#include <qpushbutton.h>
int main( int argc, char **argv )
{
QApplication a( argc, argv );
QPushButton hello( "Hello world!", 0 );
hello.resize( 100, 30 );
a.setMainWidget( &hello );
hello.show();
return a.exec();
}

I need some advice.
I am working on an application that needs to have customizable forms (Visual C++ MFC GUI). This application is targeted at the general population. One of my goals for this app is that 95%+ of the users will be able to easily customize the forms to their needs. This is, infact, a key requirement for the app.
I have worked with my own form designer engine (yuck!), Dundas Hyperforms (yuck!), VBA and a couple others from this site and others. The main problem with all of these is that my experience indicates that the average user won't be able to figure out how to customize them. Each of these form engines tries to be everthing to everybody. (One size fits all).
What I am thinking of doing is creating a form designer which will allow the user to add fields to it but it will automatically position them. The user would use a simple dialog with 2 listboxes (side-by-side) and about 6-7 buttons to design the form. The left list box would contain the available fields and the right list box would contain the fields included on the form. Buttons would be present to reorder the fields on the form, add new fields and add/remove fields from the form.
This form engine would not support activeX controls, scripting or anything fancy. Just a standard set of controls (edit, label, date picker, combo box, etc.)
My question is this: Do you think the averate user can figure out how to do this? AND will the more advanced users be frustrated by this?
What's your advice?

The ones that need it will. The ones that don't might complain about not being able to figure it out, but if you include a comprehensive set of pre-defined configurations, they should be alright. Just make sure the form editor isn't *annoying*, i.e., if you have buttons that jog field position, make them autorepeat if they're held down, allow drag&drop if it makes sense to do so, etc.

You could have an advanced mode, which is turned off by default, that would let an advanced user modify more stuff (such as the positioning)
If you just want to experiment with UI stuff, then probably the best thing to do would be to knock together a simple prototype, and get assorted people to play with it, and give feedback

Hi,
I just wonder if I can use PThread (or any PThread class) in VC++. How about java and visual basic?
Thanks

Sorry, this is not an answer but a question : what´s a PThread ? ("You still have to learn a lot, young Padawan")

You can find a Win32 pthreads library at http://sources.redhat.com/pthreads-win32/

The problem is that the dialog has not been created yet so you can't set its text, and SetWindowText isn't a member function of the CColorDialog class. It should be something like this:
CColorDialog clrDlg;
clrDlg.m_SomeMemberVariable.NameVariable = "Select Object Color";
clrDlg.DoModal();
-Raffi

Well, this is a rather common misundertanding about MFC dialogs and the underlying windows. When you construct a CColorDialog (or some other type of dialog, for that matter), it is only the MFC wrapper that gets created. It is in the middle of DoModal that the underlying HWND is actually created and attached to the MFC object. Unfortunately, after calling DoModal is all too late for setting the caption (the dialog has already exited.) The way out of this dilemma is as follows:- Create a class derived from
CColorDialog, say CMyColorDialog.
- Provide a constructor accepting the caption that stores it in some member variable defined to that purpose, say
m_caption.
- Add an
OnInitDialog handler and set there the new caption with SetWindowText(m_caption).
Good luck!

I want to save some information in SYSTEM REGISTRY and then retrieve.
any one?

Why don't you use one of the classes available here at CP ?

You can use a registry class as Colin Davies suggested but if you want to directly use API, look up the following functions on MSDN
RegOpenKeyEx
RegCloseKey
RegEnumKeyEx
RegCreateKeyEx
RegDeleteKey
RegQueryValueEx
and
RegSetValueEx

How about the Old style WriteProfileString, WriteProfileInt and to retrieve use the GetProfileInt and GetProfileString. It works for me and it will work for you too. Make sure that in the App's InitInstance change the SetRegistryKey function if you don't want the stuffs to get saved in the "Local AppWizard.. Bla bla".

Hi: I am trying to create a window using Microsoft, Visual C++ with MFC. I created the window with an “edit” box that is supposed to receive input from the keyboard. I also created a variable under the “edit” box IDC_BUTTON1 so that when I input data to the “edit” box, it can be transferred into the variable associated with the IDC_BUTTON1 and used in a C++ program. However, when I execute the program, nothing gets into the variable created. I am not sure of how I input data and transfer it to my C++ program. Any help will be appreciated.;P
