I'm programming in C++ using Visual Studio 2010 using a Windows Form to create stuff. Friggin' hating it! I want to use vector arrays, which I can do easily enough in a native C++ program but I can't find any walk thru examples for use in a Form. I've included cliext/vector in the main.cpp. If I try and include in the Form.h it tells me I can't do it. When I try and create a vector array variable it tells me I have a syntax error missing ';' before '<' All I want to do is create 6 arrays (int/float/2 Point/2 String^) that I can easily add data too then read it back later. I just need an example of how to set it up. [Edit] Not sure how posting code that doesn't work is going to help in getting a link to a working example but sure... I'll go along with it. Oh, if I add using namespace cliext; at the top of my .h file I'm told that cliext isn't a class or namesapce. The first load of errors are all about how the vector syntax is wrong...then I get a load of errors stemming from the variables being undefined later on. <pre><code>#pragma once namespace Lab6_Draw_V1 { using namespace System; using namespace System::ComponentModel; using namespace System::Collections; using namespace System::Windows::Forms; using namespace System::Data; using namespace System::Drawing; /// <summary> /// Summary for Form1 /// </summary> public ref class Form1 : public System::Windows::Forms::Form { public: Form1(void) { InitializeComponent(); // //TODO: Add the constructor code here iPix=1; sColorLine="Black"; sColor="Black"; // } protected: /// <summary> /// Clean up any resources being used. /// </summary> ~Form1() { if (components) { delete components; } } private: System::Windows::Forms::Panel^ panel1; protected: private: System::Windows::Forms::ColorDialog^ colorDialog1; private: System::Windows::Forms::Label^ colorBox1; private: System::Windows::Forms::RadioButton^ BtnPix1; private: System::Windows::Forms::RadioButton^ BtnPix3; private: System::Windows::Forms::RadioButton^ BtnPix5; private: System::Windows::Forms::ToolStrip^ toolStrip1; private: System::Windows::Forms::ToolStripButton^ toolStripBtnLine; private: System::Windows::Forms::ToolStripButton^ toolStripBtnSquare; private: System::Windows::Forms::ToolStripButton^ toolStripBtnEllipse; private: System::Windows::Forms::ToolStripButton^ toolStripBtnColor; private: System::Windows::Forms::Label^ labelPos1; private: System::Windows::Forms::Label^ labelPos2; private: /// <summary> /// Required designer variable.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
