You mean that it doesn't create one for you? Aww! Frown | :(

Which headers do I include? Thanks! Wink | ;-)

Sorry, I have no idea what stdafx.h is there for... Dead | X|

But I looked at an example one for another app, and it looks quite simple... I thought it was a huge file with lots of weird stuff... :-P
But now I'm facing a new problem... Mad | :mad:

How do I run my dialog once the app started? First I got a runtime assertion error, I changed from Debug to Release and it fixed... Then it complained about not having a main() method, I added one, but how do I start the dialog? Thanks! Wink | ;-)

I think that you have serious problems. I suggest that you start by reading about the MFC. If you know how it works, you'll see the origin of your problems.

Hmm... do you know of any tutorial for the VC++ 1.52 version? All of them out there are either for 6.0 or 2003... Confused | :confused:

Hello,

I don't think MS supports that version anymore. Why do you want it anyway.

I search on Web, and did not get clear answer. Now here is the way to catch double click action by a ordinary button. Laugh | :laugh:

create CMyButton based on CButton.
add WM_LBUTTONDBLCLK message handler.
use wizard add variable for the IDC_BUTTON1. let it's type be CMyButton.
that's it.
You will catch Bouble Click action my CMyButton.

Easy huh!

Maybe so, but you need to question using double-click with a standard button. Windows users don't typically double-click buttons, so you're going to have a hard time training them to do so in your application. Presumably, the normal click on your buttons performs some other action. You'll also have the danger of that action being performed instead, even though the user thought they were performing a double-click.

Try to use BN_DOUBLECLICKED and your button need to be Notify.

Extremely basic ? about VS 2005.

I am currently familiar w/ VC 6.0.
I downloaded the trial of VS 2005 Express (just C++) to try out.
I created a new "Windows Forms App" and added a couple of controls.
When I add an event handler (such as _Click for a button), the IDE creates the entry in the .h file, but I don't see a .cpp file.

Here's what's in the .h file:

private: System::Void button1_Click(....

I don't think I am now supposed to put my code in the .h file, so... 1) am I supposed to create the .cpp file myself? or 2) did I miss something such that the .cpp file did not get created when it should have?

I know this is really simplistic, and I feel like I'm just overlooking something, but some advice to point me in the right direction would be nice.

Thanks.

PS: One other simple thing. I figured out the following to do a simple MessageBox:

System::Windows::Forms::MessageBox::Show("Button pressed!");

Surely there's a shorter way...!

Thanks again.

This is the VC++ forum, your questions are about C++/CLI, for which there is the C++/CLI forum.

Guess so. I tried it and got the same result.

Provided you have using namespace System::Windows::Forms in the translation unit, you can simply do MessageBox::Show(...)

Crap! I thought CLI was for regular (non-Visual) C++... where's that then? Unsure | :~

Thanks!

BTW, David, I don't know how to do it in C++, but in C# you used:
using System.Windows.Forms;
It should be quite similar... Wink | ;)

There is an icon ,and I want to set the icon as a item's image without backgroud color in a CTreeCtrl in MFC.
How do I do?
attaching my code:
hIcon=(HICON)LoadImage(NULL,GetIconFromFile ("CLSDFOLD"),IMAGE_ICON,16,16,LR_LOADFROMFILE|LR_DEFAULTSIZE);
iconIndex=m_DeviceImage.Add (hIcon);
HTREEITEM hti1=m_wndDeviceTree.InsertItem
(_T("CATEGORY"),iconIndex,iconIndex,hti);
DestroyIcon(hIcon);

The icon is able to display,but it is black backgroud color.why??
help me
would you write some code?

I have a number like 400

I have another number like 666

Is there anyway using bitwise operators I can extract ONLY the bits which are used to make 400 and determine if all those bits are set???

I have read PJ Arends bitwise article numerous times, but still I am missing something and I need this for a solution...

Basically MASK only certin bits and determine if all are set???

Is this possible? Can you show me how please??? Smile | :)

It's frustrating being a genius and living the life of a moron!!!

This makes no sense. If all of the bits of a number are set, then the number is 'fully intact' (i.e., there's nothing to test).

Basically whats happening here is I am trying to determine which checkboxes in an FTP program should be checked...

Based on the linux permissions of the file...

So, For example:

777 would require all the checkboxes RWX for Owner/Group/Other to be checked...

Whereas 400, would require ONLY the READ/Owner to be checked...

I have the permission bits, ie: 777 or 666 or 400...

Now i'm trying to use this number and programatically determine which of the corresponding checkboxes need to be checked...

I cannot use any FTP helper functions, etc...I must do this completely independant of any library...

The reason I asked if it's possible to localize a certain number inside another...is because...

400 in binary = 110010000 - 3 bits are SET, but ONLY one checkbox (READ/Owner is checked)

However, 666 in binary = 1010011010 - 5 bits are SET and all READ/WRITE for Owner, Group, Other are checked!!!

A trivial:
((666 & 400) == 400)

Doesn't work!!! I'm not sure why it doesn't work...but it doesn't work...atleast the last time I tried it it didn't work Smile | :)

Now does it make sense what I am trying to accomplish???

Any ideas???

666 => 1010011010
400 => 0110010000

bitwise & => 0010010000
It probably will not match 400 ( 0110010000 ).

In Unix, those permission are in octet.
So, you may want to try

((0666 & 0400 ) == 0400 )

If I understand your problem correctly, I probably will try
different approach.

You probably have 9 checkbox for all permissions.
I probably will have a function to take the
permission & all 9 checkbox.

Inside the function.

if ( permission & 0400 )
ownerRead->SetCheck ( TRUE);
if ( permission & 0200 )
ownerWrite->SetCheck ( TRUE);
& etc.

You're missing the fact that the Unix numerical permissions are octal (base 8) numbers. This means 400 octal is 100000000 in binary and 666 octal is 101101101 in binary.

Re: bitwise operations

Indeed. Each digit in an octal number, is represented by three bits in the binary number system. E.g: base 8: xyz => base 2: x₀x₁x₂y₀y₁y₂z₀z₁z₂

Correction. 666 in base 8 is 110110110 in base 2.

I need help with printing text from a view.

I have an SDI app with several views (mostly CFormView), one of which is a CEditView class. From this class I need to add a "centered" heading with a larger font and set a decent margin to print only text.

I would like some help understanding how to use OnPreparePrinting, OnBeginPrinting, and OnEndPrinting functions that are already in my edit class. I know there are a few classes for printing but if I don't understand how it all works, they are of little value to me.

Another problem is that the book stores in my area have mostly .NET stuff and I'm using VC++ 6.0.

Thanks!
