如何在可视C ++控制台应用程序中使用zedgraph.dll? [英] how to use zedgraph.dll in a visual c++ console application?

问题描述

您好，我使用Visual Studio，Visual C ++ 6和Visual C ++ 2008进行即时编程，这是一个计算数学方程式的控制台应用程序，我想用zedgraph.dll绘制响应，但我做不到.

如何在控制台项目的Visual C ++ 2008中使用zedgraph.dll(绘制图形功能的dll)?我无法将这些dll加载为参考.

在devloper的Wiki中，有一个控制台示例，但它在C#中，并且它们使用简单的添加引用"来添加控制台.和c ++没有这个功能，您能帮我吗?

解决方案

Vielen Dank！好的，谢谢，但是我已经在VS C ++ 2008中创建了一个控制台应用程序项目，然后单击project-> Properties ...--> Framework and reference.并且有:

具有按钮添加新引用..."的框
具有添加路径..."和删除路径"文本的按钮.

如果单击第一个，则只有一个对话框，显示项目"，其他都没有.

如果单击添加路径..."，则会出现一个对话框，显示添加参考搜索路径"和浏览"按钮.

这仅对于-win32控制台应用程序是一个问题，因为我已经使用-CLR控制台应用程序完成了您的解决方案，并且效果很好！

非常感谢！

构建VS 2008 C ++控制台应用程序确实非常简单.创建一个控制台应用程序项目.在项目属性对话框中，选择公共属性"，然后选择框架和参考".您将必须添加System.Drawing，System.Data和ZedGraph.前两个是从".NET"寄存器中添加的.对于最后一个，您必须更改为浏览"寄存器，并同时添加您的ZedGraph dll.

这是进入应用程序主要功能所在文件的源代码(此代码替换了主要文件中的所有内容):

 //  ConsoleZedGraph.cpp:主项目文件.

给出了winforms C ++应用程序的源代码以及ZedGraph网站上的说明，提出此解决方案并不是什么大问题.

Hello, im programming with visual studio, visual c++ 6 and visual c++ 2008 a console aplication that compute mathematical equations and I want to plot the response with zedgraph.dll, but i can`t to do it.

How can I to use zedgraph.dll (a dll that plot graphic functions) in visual c++ 2008 in a console project? I can´t load these dll how a reference.

In the wiki from devloper there is an example of a console but it is in C# and they use the easy "add reference" and c++ doe´snt have this, can you help me?

解决方案

Vielen Dank! Aufwiederschreiben.

Ok thank you, but I have created a console application project in VS C++ 2008, and then click project-->Properties...-->Framework and references. And there are:

A box with a button "Add New Reference..."
Buttons with "Add Path..." and "Remove Path" text.

If I click the first there is only a dialog that says "Projects" and nothing else.

If I click "Add Path..." appears a dialog that says "add reference search path" and a "Browse" button.

This is a problem only with a -win32 console application- because I have done your solution with -CLR console application- and it works great!

Thank you very much!

Building a VS 2008 C++ console application is really quite straight forward. Create a console application project. In the project properties dialog select "Common Properties" and then "Framework and References". You''ll have to add System.Drawing, System.Data, and ZedGraph. The first two are added from the ".NET" register. For the last one you''ll have to change to the "Browse" register and add your ZedGraph dll also.

Here is the source code that goes into the file where your applications main function was (this code replaces everything in the main file):

// ConsoleZedGraph.cpp : main project file.

#include "stdafx.h"

using namespace System;
using namespace System::Collections;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::Drawing::Imaging;
using namespace ZedGraph;

void CreateGraph(String^ fileName);

int main(array<System::String ^> ^args)
{
    String^ fileName;
    if(args->Length > 0)
    {
        fileName = args[0];
    }
    else
    {
        fileName = "C:\\temp\\TestGraph.png";
        //Console::WriteLine("You have to supply a filename for your graph!");
        return -1;
    }
    CreateGraph(fileName);
    return 0;
}

void CreateGraph(String^ fileName)
{
    // Create a GraphPane is really all you have to do
    // when using ZedGraph in a console application
    RectangleF rect = RectangleF( 0, 0, 640, 480 );
    GraphPane ^myPane = gcnew GraphPane( rect, "Überschrift", "X Titel", "Y Titel" );

    // Set the titles and axis labels
    myPane->Title->Text = L"Zwei Kurven in einem Graphen";
    myPane->XAxis->Title->Text = L"Zeit, Tage";
    myPane->YAxis->Title->Text = L"Wert A";
    myPane->Y2Axis->Title->Text = L"Wert B";

    // Make up some data points based on the Sine function
    PointPairList ^list = gcnew PointPairList();
    PointPairList ^list2 = gcnew PointPairList();
    for ( int i = 0; i < 36; i++ )
    {
        double x = (double)i * 5.0;
        double y = Math::Sin( (double)i * Math::PI / 15.0 ) * 16.0;
        double y2 = y * 13.5;
        list->Add( x, y );
        list2->Add( x, y2 );
    }

    // Generate a red curve with diamond symbols, and "Alpha" in the legend
    LineItem ^myCurve = myPane->AddCurve( L"Eins",
        list, Color::Red, SymbolType::Diamond );
    // Fill the symbols with white
    myCurve->Symbol->Fill = gcnew Fill( Color::White );

    // Generate a blue curve with circle symbols, and "Beta" in the legend
    myCurve = myPane->AddCurve( L"Zwei",
        list2, Color::Blue, SymbolType::Circle );
    // Fill the symbols with white
    myCurve->Symbol->Fill = gcnew Fill( Color::White );
    // Associate this curve with the Y2 axis
    myCurve->IsY2Axis = true;

    // Show the x axis grid
    myPane->XAxis->MajorGrid->IsVisible = true;

    // Make the Y axis scale red
    myPane->YAxis->Scale->FontSpec->FontColor = Color::Red;
    myPane->YAxis->Title->FontSpec->FontColor = Color::Red;
    // turn off the opposite tics so the Y tics don't show up on the Y2 axis
    myPane->YAxis->MajorTic->IsOpposite = false;
    myPane->YAxis->MinorTic->IsOpposite = false;
    // Don't display the Y zero line
    myPane->YAxis->MajorGrid->IsZeroLine = false;
    // Align the Y axis labels so they are flush to the axis
    myPane->YAxis->Scale->Align = AlignP::Inside;
    // Manually set the axis range
    myPane->YAxis->Scale->Min = -30;
    myPane->YAxis->Scale->Max = 30;

    // Enable the Y2 axis display
    myPane->Y2Axis->IsVisible = true;
    // Make the Y2 axis scale blue
    myPane->Y2Axis->Scale->FontSpec->FontColor = Color::Blue;
    myPane->Y2Axis->Title->FontSpec->FontColor = Color::Blue;
    // turn off the opposite tics so the Y2 tics don't show up on the Y axis
    myPane->Y2Axis->MajorTic->IsOpposite = false;
    myPane->Y2Axis->MinorTic->IsOpposite = false;
    // Display the Y2 axis grid lines
    myPane->Y2Axis->MajorGrid->IsVisible = true;
    // Align the Y2 axis labels so they are flush to the axis
    myPane->Y2Axis->Scale->Align = AlignP::Inside;

    // Fill the axis background with a gradient
    myPane->Chart->Fill = gcnew Fill( Color::White, Color::LightGray, 45.0f );

    Bitmap^ bm = gcnew Bitmap( 1, 1 );
    Graphics^ g = Graphics::FromImage( bm );
    myPane->AxisChange( g );
    // Retrieve the image
    Image^ img = myPane->GetImage();
    // Save image as PNG
    img->Save(fileName, ImageFormat::Png);//, ImageFormat::Bmp);
}

Given the source code for the winforms C++ application and the instructions on the ZedGraph website it wasn''t to big a problem to come up with this solution.

Enjoy! :cool:
