I have the same question as the guy below this form, but my question has to do with MDIparents and childs. I followed a guide that told you how to, but I kept getting errors everytime I built it.
http://www.functionx.com/vcnet/Lesson07.htm[^]
I used this guide, but it gave me errors saying its a mix between Managed and nonManaged C++.
I'm new to MDIParents+childs and was wondering if i can get some help with this.
And when i used what you told the guy below me i got these 2 errors.
System.InvalidOperationException: Starting a second message loop on a single thread is not a valid operation. Use Form.ShowDialog instead.
System.InvalidOperationException: Form that is already visible cannot be displayed as a modal dialog box. Set the form's visible property to false before calling Show.
I did what it said both times, but still got same problem.

I don't know what you already tried to do.
But I think it is quite easy to add a MDI child form.
In the MDI-Parent, set IsMdiContainer = true.
And to create a new Child (e.g. from a event handler
within the MDI-Parent):
Child^ child = gcnew Child();
child->MdiParent = this;
child->Visible = true; Alex

Hi, I need use two forms in application. Is some easy way exists? I do that in Delphi, but in C++/CLI Win Form app is something understandable. I was googling for some easy practise, but not found it.
Is there something who help me with piece of code for two forms?

you can use multiple forms in C++/CLI. Just right click on your project and click "Add new Item..."

Sure, but I cant use (in example) in Form1 ->
Form1.Visible = true; OK
Form2.Show = true; it doesnt know Form2
(I maybe use :: )
I must include something to Form1?

You can create 2 separate forms just as teejayem suggested, but if you want them completely independent of each other (i.e. Form2 is not a child of Form1), then you need to modify your <project_name>.cpp file that opens your main form. This file contains your main loop, and probably has a line like
Application::Run(gcnew Form1());
You would need to change this to create your Form1 and Form2 objects, show them, and then start your application. You might need a DoEvents loop, but there might be a way around that.

You have to include the form2.h in your form1.h file for you to be able to use it
#include "Form2.h"
also "Show" isn't a property, it is a method. You shouldn't be trying to assign a boolean to it

Thank you, it works, but there is still little problem.
Form1::Visible = false;<br />
<br />
<br />
Form2->Show();

I'm guessing that is because your varaible name is the same as your class name. so the compiler is thinking your trying to call a static method. Change your variable name to something more unique
System::Windows::Forms::Form^ myFrm2 = gcnew System::Windows::Forms::Form()
myFrm2->Show()

Oh, thank you for your help. I was googling with "c++\cli" AND "#include"Form2.h"" and I found solution. It was that what you wrote. Same name Form2. THANK YOU

I need a simple example on how to use OpenFileDialog(). I don't want to extend it or enhance it (I did search for articles), just use it. Even after searching the entire Visual Studio directory, I cannot find the right files to include so that the compile stops telling me that OpenFileDialog is an undeclared identifier.
Do you have a link that will help me out?
Thank you.
Thanks for your time

example
to use this class you need to include the System.Windows.Forms assembly and add the namespace on top of your .h

Hello teejayem,
I feel like there are too many questions to ask. I check your example link, but Microsoft leaves so much out and is so different from my code that I don’t understand it.
RE: to use this class you need to include the System.Windows.Forms assembly and add the namespace on top of your .h
Does this mean to put the below at the top of my .h file?
#include “System.Windows.Forms”
using System.Windows.Forms
The on button function in my code, created by VS, starts like this:
void Ctest1Dlg::OnBnClickedSelectLogFileButton()
{
And does not look anything like the example code:
void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
I read about the ^ character and still don’t make any sense of that.
I wonder why we need more obscure characters in C++. It seems like we are trying to turn C++ into APL.
And just to be certain, I am using Visual Studio 2008 under Windows XP Home.
Thanks for your time

"RE: to use this class you need to include the System.Windows.Forms assembly and add the namespace on top of your .h"
you need to add the namespace like:
using namespace System::Windows::Forms;
"I read about the ^ character and still don’t make any sense of that."
"In C++/CLI the only type of pointer is the normal C++ pointer, and the .NET reference types are accessed through a "handle", with the new syntax ClassName^ instead of ClassName*"

"I wonder why we need more obscure characters in C++. It seems like we are trying to turn C++ into APL."
Hopefully you are talking about C++/CLI and not pure C++! You cannot use managed classes in a pure C++ application.

C++/CLI should be treated as a separate language.
C++ is still C++. No obscure characters have been added.
Are you sure C++/CLI is what you want to use? There's also
a way to use the open file common dialog from native C++.

Hello Mark,
RE: Are you sure C++/CLI is what you want to use? There's also

No, I am not sure at all I want to mess with this. I activated Help from my Visual Studio to find out how to open a dialog for opening a file. I wound up here, but I am not at all sure where I want to be.
Thanks for your time

Hi,
I am writing a pure C++ programe. I need to use strcpy_s() in my programe. As of now my compiler is not supporting strcpy_s(), what should I need to do if i wan u to use strcpy_s(). Do i need to download any library of standard (ISO/IEC TR 24731 ), is it free?
I don know how to go about it, so please let me know how to get more info about it?

You cannot use strcpy_s in versions of C++ before VS 2005. Download Visual Studio Express for C++ if you want to use it for free. However, you loose MFC and ATL, for example. Please, direct your "native" C++ questions to the C++/MFC forum.
