If you need to ask this, I am not sure you need to be using Windows Forms. Unsure | :~

nish, it seems that the thread was moved from the VC++ forum, but it's not a managed question actually...

He wants to use MessageBox::Show which seems to indicate that he's using Windows Forms. Probably mixing that with MFC too - so most likely a mixed mode app.

yeah, it's what at thought at first, but finally, nothing indicated he want to use MessageBox::Show() above all.

i think much that he doesn't really know what he does, and is a little lost with all the existing APIs. maybe he say somewhere on the internet that MessageBox::Show() existed, thinking that it would work in every situation. though, when he asked me what Managed C++ was, it became obvious that he was absolutely not aware of the difference between managed and unmanaged code, and lesser what mixed code could be...

don't you feel it like this ??

I got that impression, too. So that is why I put up a link to wikipedia about managed code.

Perhaps, it's so. Let him ask a clearer question on the VC++ forum if he wants to. Let this thread remain here, so people will know how to use MessageBox::Show in a mixed mode app. Helps to improve search results.

Yup! I'm absolutly confused!
I have no clue what so ever what I'm doing when it comes to GUI design with Visual Studio.

I've been taught how to do console type design using emacs and compiling it with gcc but I've never used visual studio b4.

I'm sorry I'm asking so pretty dumb questions, it's just that there's no simple getting started with gui book.

I'm still trying to figure out MFC vs. windows form. I know with the windows form you can add dialogs and controls. With MFC it gives you a project whether it's MDI or SDI you choose but you also have the option to change the base class to CFormVew and then you can play with the dialog that way. Other wise I don't know how else to add dialogs and controls to and MFC...

Thanks Sigh | :sigh:

I've created a Button and what i'm trying to do is when I click the button I want a message box to pop up...

void ksclass::OnBnClickedButton1()
{
::AfxMessageBox(_T("Hello Wolrd !"));
// TODO: Add your control notification handler code here
}

the ::AfxMessageBox(_T("Hello Wolrd !")); helped with the errors but when I run then click the button... nothing happens...

Thanks Big Grin | :-D

If this is an ordinary C++ application, you can use:

::MessageBox( 0, "Hello, World!", "", 0);

It is the global scope operator. Instructs the compiler to use the global MessageBox function.

You need to #undef the MessageBox macro definition before using the .NET MessageBox class.

#undef MessageBox<br />
MessageBox::Show("hello");

You'll need #undef MessageBox after #include "stdafx.h" - it's trying to use the standard MessageBox rather than the .net one.

Hello,
I played a bit with the vcCodeModel and it is a great tool to gather information.

However, the one functionality I couldn't find is the one that's already supplied by the ObjectBrowser: Discovering which functions calls to which, the way ObjectBrowser does.

Anyone has an idea?

How to embed external document?

In the good old days I believe people were using the arcane technology which came to be known as COM+ to embed other application's document in their own document.

Like a Word with document a Windows Media Player or Excel or Visio document inside, double click on it and *bang* you coud start edit it using Excel/WMP/Visio toolbar.

Apparently even OpenOffice could do that.

Now here is my question:
I'm a new generation programmer. Blissfully ignorant of such thing.
But I would like to know and embed Word, Excel or other kind of document in my application's own document!

How could I do that?

And is there an up-to-date technology (i.e.: .NET API) to do that?

DataGridView in MFC

I seem to have a problem using the DataGrid/DataGridView within a MFC dialog (using the CWinFormsControl< > template).

I create a DataSet from a Xml file and then set it to the DataSource. I also set the DataMember to the appropriate table name, but nothing is displayed in the grid view. I tried other various approaches, but nothing seems to work.

I have no problem setting this up in WinForms - it just won't display in MFC. I know the data's there because I can actually step right into it from the DataGrid object - it just won't display - the ColumnCount is still 0.

Confused | :confused:

What's the problem? Has anyone else experienced this? If so, has anyone found a way around this?

I just don't understand why this won't work.

Using C# controls in managed C++

Hi there!

Newbie question: I want to develop an app using managed C++ and Windows Forms, is it possible to use some of the nice C# controls I see on this page in my app?

If this question is about "is it easy to use them", the answer is yes. As most C# controls are compiled into assemblies(DLLs), you should be able to use them in your C++ applications with no or little problems.

If your question is about copyright, consult with the author or CP staff about terms and conditions.
