I am trying to use radio buttons in Studio 2008 and I don't find it as easy as it used to be in VC++ 6.0 or maybe even in Studio 2005.
Here is what I have. I have a group box that contains three sets of radio buttons.
Set 1: (altitude) meters or feet
Set 2: mach or velocity
Set 3: (if velocity, units) ft/sec, m/sec, mph, knots
I layed this out by creating a label for each set and then putting down the buttons for the current set I was building.
Static label 1: Altitude is: (then I put two radio buttons - meters, feet)
Static label 2: Specify: (then I put two radio buttons - mach, velocity)
Static label 3: Units for velocity: (then I put down 4 radio buttons....)
When I click a button in Set 1, i want it to update a variable - m_nAltitudeFormat.
When I click a button in Set 2, i want it to update a variable - m_nMachOrVelFormat.
When I click a button in Set 3, i want it to update a variable - m_nVelOptFormat.
Studio2008 doesn't do the simple things (??) that previous versions of Studio used to like create the message mapping.... help! (when i tried cut/paste old method, got into more trouble.)
Thanks,
John John

When you group your radio buttons, you can have only one control variable. Upon DDX the variable gets updated based on the option selected. 0,1 or 2. What do you miss here?

I would try three separate group boxes, but since I can't even see a listing of the IDC_ resource for any of these buttons, I'm totally infuriated  with Studio 2008.
You all probably have a general idea of how I'm trying to tie each set of buttons to a single integer variable. So when I click a choice for altitude (either meters or feet), that variable will be set to 0 or 1. Likewise with the other sets of radio buttons.
I can't even assign a variable for the control itself so that I can disable/enable each of the 4 velocity units - enable them when velocity chosen, disable when Mach chosen.
Studio2008 gets my goat

Stay cool  . Select the control, right click, "properties". You will get it's ID from the ID property. Any control you drop on the dialog will have it's ID.
Also,you might know, you can enable/disable any control without creating a control variable.
GetDlgItem(RESOURCE_ID)->EnableWindow(true/false);
Also, I'm just noticing. The member variable for Radio button DDX is by default is BOOL! quite misleading. It should've been int rather.  God only knows why they changed it to BOOL.
Also any beginners who would think BOOL as bool will have an excellent day

Thanks for this advice! I will try it out.
Regarding the single group box, I think I will create separate group boxes for the 3 sets of radio buttons I have, but just make them NOT VISIBLE (hide the group boxes).
Thanks again.

Hi All,
Anyone have c code for Boyer-Moore or BMH? I don't want to take the time to translate (and debug) pseudo code from my Algorithm Analysis textbook. I'd like to paste and compile.
No wiki please. I already know their stuff is broken. How much crap can one site publish and claim it is fit for consumption?

I ran across these. Unfortunately, some assembly is required and there are no instruction on calling 'void* p = Find(needle, haystack)'. Perhaps I am asking for too much.

Run it: Wiki's Boyer-Moore Horspool[^] implementation.
Here's one of the best examples. A fellow claimed Dr. Adler's ADLER-32 reference implementation was wrong because it did not agree with wiki: Need peer review: May have found mistake in Adler-32![^].

Hi Joe,
That was it. I did modify a bit to get a compile under boring old 'C': pSkipTable[(unsigned)pSearchStr[i]]
Thanks.

I've been using Visual C++ V6.0 for some years now. I believe it's not possible to reuse the code for a dialog box created in one app in another. Is this true? If not, how do I do it? If it is true, is there a more recent version of C++ that permits reuse? Many thanks, David George

What do you mean by "code for a dialog box"? Do you mean the class derived from CDialog or do you mean the resource of the dialog that sits in an .rc file?

That was quick! I think I mean both of them. First the dialog resource created in the dialog editor and the class, based on CDialog, used to manage it. Many thanks for a speedy response. DG

Unless you're not telling us all of your requirements, the two pieces you mention can be put into another project with little to no changes.

The requirement I have is simply to copy the code (both resource and management class) from a prototype program and paste it into another different program, so it can be used with little or no modification. I have no specific program in mind at the moment. But I would like to build a library of dialog resources for future programs I write if this is possible. I have no idea how it could be done. Once again, many thanks, DG

As other speedy people already pointed out, you can reuse dialog resources and classes, unless they are not written to be reusable. I used an .rc2 file, giving a "string ID" to the dialog resource instead of a numeric one, placing the control/commond IDs into a "custom resource.h" and of course the .h and .cpp for the class of the dialog to move commonly used things around projects and this works fine, you just have to remember that you have to explicitly set the .rc2 to be compiled by the resource compiler tool otherwise the resource won't be added to your executable and then you can scratch your head why your dialog does not get displayed when it should.

oh yea!
that brought nostalgic memory when we did all sorts of resource sharing in RC2 files in the late 90's.

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

As I recall, you can copy a dialog box from the resources of one VC6 project to another. You open them both with the dialog resources visible, hold down Ctrl, click on the resource for the dialog you want to copy, and drag it to the resources window of the other project.

Hi,
I've reused dialogs where I made a .h and .cpp file that defined the class and a .rc file to define the dialog layout. I based the class on ATL::CDialogImpl<...>. Though I couldn't use a .rc file straight from one project in another, I had to do some work to make sure the .rc file for the dialog contained nothing but information on the actual dialog. I then #include'd the .h and added the .rc as a resource to a new project.
