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

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.

Hi guys and gurls,
Does anyone know how u can get two dates and then work out the difference s that it can display someones age?
|
|
|
|
|
In MFC:
To get two dates from controls on a dialog, look at: CDateTimeCtrl.
To work with date / times, use CTime.
To subtract them, you can use CTimeSpan also.
That should give you things to search for and learn from.

Why are you posting this in the C++ forum then ? 
|
|
|
|
|
sorry everyone i get them mixed up everytime visual studio
|
|
|
|
|
So, you are using Visual C++ then ?
Which kind of application did you create (console, win32 or MFC) ?

Good pun. 
BTW be aware: Visual Basic developers shouldn't taint this forum.

That's no sooo difficult. Like you are able to compute, inwardly, someone's age, given its date of birth, so you should be able to code the algo.

It actually doesn't look a good plan.
