(I do work in c++, and I do know how to use classes...classes is the answer for my problem but it's a lot of work).
I didnt say that Im not using classes...I said I want to do it without using classes...meaning:
the question is "can I do it in a simple and more primitive way ?" maybe something like "namespace" or structures ?

Yes, I can see that you're working in C++, but, again, this is the C++/CLI forum, and you are not using C++/CLI as far as I can see.
Of course you can write anything you like without using classes, just like I can walk to the store instead of driving. You are not forced to use the tools that make yuor job easier.
Oh, and a struct IS a class, they are the same thing, the only difference is the default access modifier.

I made my algorithm in visual c++2005, now I want to do an interface in VC++2005 to this algorithm but the code has only functions not classes or something like this and I put my functions in the main application source file(forminterface.cpp) ...a short example is written like this...:
#include "stdafx.h"
#include "Form1.h"
using namespace forminterface;
.................
void prepareitems(item *f, item *l, int *w, int *h, int *d, int *ra, int *rb, int *rd)
{
item *i;
int k;
for (i = f, k = 0; i != l+1; i++, k++) {
w[k] = i->dx; h[k] = i->dy; d[k] = i->dz;
ra[k]=i->rx;rb[k]=i->ry;rd[k]=i->dz;
}
}
..............
[STAThreadAttribute]
int main(array<system::string ^=""> ^args)
{
// 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;
}
I want to call this function in my "start button"(private: System::Void StartPackingbutton_Click(System::Object^ sender, System::EventArgs^ e) {} ......of the interface but I don't know how or if I must declare this function in other place because it give me error like"prepareitem is not a member of global namespace"....please help me I am disperate ...I don't know where to put the functions of my algorithm and in this way to make the conection with my interface...

Looks to me like it's not visible from where you call it ( assuming that it's prepareitems and not prepareitem in the error ). Why not wrap this in a class, so you have a header file you can include to make it visible ?

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.

Hello ,
This piece of code is meant to browse for a file , display the path and display the content , its browsing but not displaying the filepath and content , can anyone help with this?
OpenFileDialog^ fileChooser = gcnew OpenFileDialog();
try{
fileChooser->InitialDirectory = "C:\\My Documents";
}
catch( ... ){
MessageBox::Show("No C:\\ drive", "Error", MessageBoxButtons::OK, MessageBoxIcon::Error);
}
fileChooser->DefaultExt = "*.rtf";
fileChooser->Filter ="Rich Text Format (*.rtf)|*.rtf|"
"Text Files (*.txt)|*.txt|"
"All Files (*.txt; *.rtf)|*.txt;*.rtf;";
fileChooser->FilterIndex = 1;
Windows::Forms::DialogResult result = fileChooser->ShowDialog();
if(result == System::Windows::Forms::DialogResult::OK)
return;
//get specified file name
fileName = fileChooser->FileName;
//show error is user specified invalid file name
if(fileName=="")
{
(MessageBox::Show("Invalid File name","Error!", MessageBoxButtons::OK, MessageBoxIcon::Error)); } else
{
file_richTextBox->Text ="";
ReadFileInfo(fileName);
}//end of else
}//end of browseButton_Click
try{
input = gcnew FileStream(filenam, FileMode::Open, FileAccess::Read);
FileInfo^ fInfo = gcnew FileInfo(filenam);
//Display filepath
String^ fname = fInfo->FullName;
file_textBox->Text = fname;
//Check file extension and load file info
fname = fInfo->Extension->ToLower();
if (fname->Equals(".rtf"))
file_richTextBox->LoadFile(input, RichTextBoxStreamType::RichText);
else
file_richTextBox->LoadFile(input, RichTextBoxStreamType::PlainText);
input->Close();
}
catch( ... ){
MessageBox::Show(String::Format("{0} is not a valid text file.", filenam),
"Error!", MessageBoxButtons::OK , MessageBoxIcon::Error);
}
}

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.

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.

If I have this code made in the Form.h of may project, how can i make the conection in
the main project file(.cpp) for variable "W".....please help.....can you give me a link or something like that where I can learn to do the conections between the variables from interface(form) and my algorithm(code)....
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.
