I don't know how to do this ...I go to Source file->add class->visual c++(c++ class)->and I create a new class and a new header like this?
#include "StdAfx.h"
#include "gt.h"
gt::gt(void)
{
}
#pragma once
ref class gt
{
public:
gt(void);
};
how can I call this function or this class in my ...StartPackingbutton:
private: System::Void StartPackingbutton_Click(System::Object^ sender, System::EventArgs^ e)
{.........?}....please help me if you know...
|

|

#include "gt.h"
Assuming the method is static:
gt.MyMethod(whatever);
If you don't know how to call a method in a class, I recommend buying a book on C++ and working through it.

How do you think it'll work if you return when the user clicks OK? Perhaps you meant to do a != check?

If you're using C++/CLI ( and if you're not, you're in the wrong forum ), you can still use STL, and the STL list class ships with full source.

I was wondering how to totally take out the title bar windows uses and replace it with a new one in a program like winamp and sonic recordnow does.

Odds are then high that you're not using C++/CLI. Try the Visual C++ forum.

Can I code in C or C++ for the Macintosh? I have borland tools. I also have Visual C++ in the Visual Studio, but have never used it. thanks, joeinorange2@aol.com

Why not? Apple claims a Mac does everything better than a PC, and a Mac has everything you will ever need preinstalled. By the way, you are in the wrong forum since this is the "C++/CLI" forum.

You are in the wrong forum, but the answer is yes, of course. In fact, the Mac I used 6 years ago came with a highly standards compliant C++ compiler.

Is there any builtin button classes in c++? If yes than please do help me.
|
|
|
|

Depends. You're asking in the C++/CLI forum, in which case the answer is yes. If you mean C++, then the answer is that there is NO GUI support in C++, you need to use frameworks ( like Winforms or MFC ) to write code specific to a platform, in order to render a UI.
Sounds like you need to better phrase your question, and perhaps ask it in the Visual c++ forum.

private: System::Void StartPackingbutton_Click(System::Object^ sender, System::EventArgs^ e) {
int W;//Container Width
try {
W=Convert::ToInt32(ContainerWidthtextBox->Text, CultureInfo::CurrentCulture);
}
int main()
{ int W;
// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
// Create the main window and run it
Application::Run(gcnew Form1());
return 0;

is there a libary or something where i can get numbers which have like 50 digits without truncation, for a program for find prime numbers etc???
also why i'm here
***************************************************

i'm trying to use the .clear() with vectors but they never work
Code:
#include <iostream>
#include <vector>
using namespace std;
int main()
{
vector<int>numbers;
int createindex = 100;
while(createindex)
{
numbers.push_back(createindex);
createindex--;
}
cout << numbers[20] << endl;
numbers.clear();
cout << numbers[20] << endl;
system("PAUSE");
return 0;
}
what am i doing wrong?
thanks i'n advanced

Yes, such classes exist.
I recommend asking for more information in the right forum ( this is the C++/CLI forum, you want the Visual C++ forum )

Can anyone help me with saving a text introduced in a text button in a different file?
|
|
|
|

You need to be more clear. Are you in the right forum ( are you using C++/CLI ) ? What do you mean by 'a different file' ? Assuming you're talking about a GUI control, you can ask it what it's Text value is, for C++/CLI the property is .Text.

You want this code in C++/CLI, or in C++ ?

If I want to appeal a windows form, from another form when I push a button, what I should do? I tried this code and I have the following error: Error error C2061: syntax error : identifier 'Results'
private: System::Void ResultsButton_Click(System::Object^ sender, System::EventArgs^ e)
{
Application::Run(gcnew Results());
}
|
|
|
|
|
private: System::Void ResultsButton_Click(System::Object^ sender, System::EventArgs^ e) <br />
{<br />
Results^ resultForm = gcnew Results();<br />
resultForm->ShowDialog();<br />
} <br />
Also, you should include the form header at the top of the form:
#include "Results.h"
