# Upgrading Visual Studio .NET Projects

undefined

## Content



When you install Spread and you have used previous versions of the product, you might need to update Microsoft Visual Studio .NET and your existing projects. See the section "To upgrade your existing VS.NET projects" below for details

## To update the Toolbox in Visual Studio .NET

For new projects, you might need to remove the existing Spread component from your Toolbox and add the new Spread component. To do so, follow these instructions:

1.  Right-click on the Toolbox, and choose the **Choose Items** option.
2.  In the **Customize Toolbox** dialog, choose the .NET Framework Components tab.
3.  In the list of Components, clear the check box in front of FpSpread where the assembly name indicates the old version, and select the check box in front of FpSpread where the assembly name indicates the current version.
4.  Click **OK** to close the dialog and place the updated FpSpread in your Toolbox.

## To upgrade your existing VS.NET projects

For existing projects, make sure the reference path is correct, and add the new FpSpread assemblies. To do so, follow these instructions:

1.  Open the project in VS.NET and close all the open forms.
2.  In VS.NET in your project, open the Solution Explorer (Ctrl+Alt+L).
3.  Right-click the Project and choose **Properties**.
4.  From the Project's Property Pages, select **Reference Path** and modify the Reference Path so it points to the location where you installed the latest assemblies. Then click **OK**.
5.  Click **OK** to close the **Add Reference** dialog and add these assemblies to your project.

Verify that the version number in the licenses.licx file is correct. For example:

Change:

`FarPoint.Web.Spread.FpSpread, FarPoint.Web.Spread, Version=8.40.20143.0, Culture=neutral, PublicKeyToken=327c3516b1b18457`

To:

`FarPoint.Web.Spread.FpSpread, FarPoint.Web.Spread, Version=15.0.20212.0, Culture=neutral, PublicKeyToken=327c3516b1b18457`
