Because of the pace of work I get very little chance to look at this discussion group but it's one of the single most useful resorces on the Net and has never let me down.

Does anyone know if there is any CD archive of the past threads or are there any plans to capture one. I would be willing to pay for such a service and I'm sure many others would be as well. I don't mean any fancy searchable database or anything like that - just a copy of the whole discussion group. It would be one of the most valuable resources for me.

Have Fun!

Problem around usage of RUNTIME_CLASS

Hello all...

I'm lost... maybe because I'm searching to deep, but anyway. My collega came to me for help, but unfortunately.. Confused | :confused:

Let's take a look to this sample:

class CMySystems{
  // Anything
};

class CMyDetails{
  // Anything
};

void xxx::SomeMethod( void )
{
  ...
  // Sets up the (docking) TabControlBar
  m_wndMyCtrlBar.AddView("Systems", RUNTIME_CLASS(CMySystems));
  m_wndMyCtrlBar.AddView("Details", RUNTIME_CLASS(CMyDetails));  
  ...
}

Now the problem:
In the class CMySystems I want to be able to use methods from the class CMyDetails.

How can I at runtime pass the 'this' pointer of the CMyDetails class to the CMySystems?

Thanks in advance,

EiSl

It seems that TabControlBar creates CMySystems and CMyDetails objects for you - one of the CRuntimeClass responsibilities is creating CObject-derived objects. If your question is how to get actual object after it is created by CRuntimeClass, the answer is: you depend on TabControlBar. This class should give you access to its views; I'd expect something like TabControlBar::GetFirstView/GetNextView. Since it's 3rd party class, I can't help you futher.

How declare a Function with 8 Inputs and 4 Outputs ??

Hi,

I would like to create a function with 8 Inputs and the result is in 4 Ouputs.

How can I declare it?

Best Regards

Re: How declare a Function with 8 Inputs and 4 Outputs ??

26-Jul-01 21:50

Hi Are you really shure that you want to have that many in and outputs in one function? Maybe the function is doing too much and you should consider splitting it up in several functions.
Else, while a function only can return one value you have to get the result through the parameters in the function using pointers or references. Something like: myFunction(in1,in2,in3,in4,in5,in6,in7,in8,*out1,*out2,*out3,*out4).

the other asy is to group your values into structures or clases (input and output)

then it's easy...

Preprocessor defines and MFC

Hi!
Does anyone know, how to determine (until preprocessor defines) the app use MFC or not, if included support MFC in static library ?

When using the DLL version of MFC, the symbol _AFXDLL is defined. When using the statically-linked version, it's not defined.
As for whether MFC is being used or not... it looks like you can check for __AFX_H__, which is defined when afx.h is #include'd.

How to Inport A Resource and its Class

Hi,
I know how to import say a dialog box from another project,
project->add to project->files->the_resource_file.rc
But don't know how to import that dialog's class from the other project.
I want to be able to import a dialog box and it's class, so I wont have to recreate member variables and all the rest of them things. How can I go about that?
Thanks

nulldreamer26-Jul-01 19:50

26-Jul-01 19:50

I did, that didn't work, might there be something wrong with my compiler?
Because even though I could see the dialog class in the class view, when I right clicked on the dialog box (in the resource editor) and chose class view, that gave me the options:
1)create a new file and
2)Choose an existing one
when I chose to associate it with and existing one, the class (of that same dialog box-imported)that was supposed to be there WASN'T, and I repeat, I could see it in the class view, and I could see the .cpp and .h files in the file view.
Now, what is going on? I really need help, I wouldn't like to waste a whole day remaking the old things.
Thanks a lot
P.S. I hope I make sense

Copy both the .CPP and .H files. And then use Project->Add to project-> files to add these files in to ur project.

I think, u have to import the resource.h file also.

nulldreamer26-Jul-01 20:07

nulldreamer

26-Jul-01 20:07

Rejeesh,
I'll do that, but you can't copy the whole resource.h there can be only one at a project. But Christian gave me an exact advice of how to do it.
Thank you guys I hope that'd work.

KingsGambit26-Jul-01 23:13

Cut and paste will work. But there should not be same values in ur existing resource.h file.

One more thing. Better u open the new .rc file in any text editor and copy the required data from the old. Do the same with resource.h also (without ID conflict).

Happy coding.

If you're only importing the rc file, you probably need to recreate the resource definitions from the old resource.h file, I would have thought. I always do this by physically copying the dialog definition from the old .rc file and pasting into the new, and then creating the new definitions directly in the resource.h file.

Hi,
I can't manage to do the importing so far.
When I import a class into the project, why doesn't it let me associate a dialog box with it. It's not in the list of existing ones (in the class wizard), even though it's in the class view. I know someone will get pissed because I'm repeating myself, but I just can't seem to figure it out.
I tried to edit resource.h, but ... well, couldn't do it
Thanks

Remove the old .clw file from u project directory. Then activate the class wizard. Just press ok in the dialog shown. UR imported classes will be available in the class wizard.

Read from the console window

26-Jul-01 12:44

I'm starting a console window application from a dialog based application, using CreateProcess, because I need to hide the DOS window. Do you guys have any idea how can I capture the output of the DOS window to display it in my dialog?
I tried to pipe the DOS application to a file, and then read from the file, but there's one problem: the DOS application writes to the file when it finishes. I need to get info from it while it is still working.

To give you a better understanding of what I'm trying to do, here's an example: I start an external compiler, and I want to display in my dialog the data that the compiler shows in its DOS window.

Thanks!
