Walkthrough: Collecting Data Using a Windows Form
This walkthrough demonstrates how to open a Windows Form from a document-level customization for Microsoft Office Excel, collect information from the user, and write that information into a worksheet cell.
Applies to: The information in this topic applies to document-level projects and application-level projects for Microsoft Office 2010 and the 2007 Microsoft Office system. For more information, see Features Available by Office Application and Project Type.
Although this walkthrough uses a document-level project for Excel specifically, the concepts demonstrated by the walkthrough are applicable to other Office projects.
You need the following components to complete this walkthrough:
An edition of Visual Studio 2010 that includes the Microsoft Office developer tools. For more information, see Configuring a Computer to Develop Office Solutions.
Microsoft Office Excel 2007 or Excel 2010.
Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Working with Settings.
The first step is to create an Excel Workbook project.
To create a new project
Create an Excel Workbook project with the name WinFormInput, and select Create a new document in the wizard. For more information, see How to: Create Office Projects in Visual Studio.
Visual Studio opens the new Excel workbook in the designer and adds the WinFormInput project to Solution Explorer.
To add a named range to Sheet1
Select cell A1 on Sheet1.
In the Name box, type formInput.
The Name box is located to the left of the formula bar, just above column A of the worksheet.
A NamedRange control is added to cell A1. There is no visible indication on the worksheet, but formInput appears in the Name box (just above the worksheet on the left side) and in the Properties window when cell A1 is selected.
Create a Windows Form to prompt the user for information.
To add a Windows Form
Select the project WinFormInput in Solution Explorer.
On the Project menu, click Add Windows Form.
Name the form GetInputString.vb or GetInputString.cs, and then click Add.
The new form opens in the designer.
Select the button, find the property Text in the Properties window, and change the text to OK.
Next, add code to ThisWorkbook.vb or ThisWorkbook.cs to collect the user's information.
Create an instance of the GetInputString Windows Form and display it, and then write the user's information into a cell in the worksheet.
To display the form and collect information
Right-click ThisWorkbook.vb or ThisWorkbook.cs in Solution Explorer, and then click View Code.
In the Open event handler of ThisWorkbook, add the following code to declare a variable for the form GetInputString and then show the form.
Create a method called WriteStringToCell that writes text to a named range. This method is called from the form, and the user's input is passed to the NamedRange control, formInput, on cell A1.
Next, add code to the form to handle the button's click event.
To send information to the worksheet
Right-click GetInputString in Solution Explorer, and then click View Designer.
Double-click the button to open the code file with the button's Click event handler added.
Add code to the event handler to take the input from the text box, send it to the function WriteStringToCell, and then close the form.
This walkthrough shows the basics of showing a Windows Form and passing data to a worksheet. Other tasks you may want to perform include:
Use Windows Forms controls on an Excel workbook or a Word document. For more information, see Windows Forms Controls on Office Documents Overview.
