In Visual Studio 2010, on the File menu, point to New, and then click Project to open the New Project dialog box.

From the list of Visual C#, Windows projects, select the Windows Control Library project template, and then type ConfigMgrTSAction in the Name box.

Click OK to create the Visual Studio project.

In Solution Explorer, right-click UserControl1.cs, click Rename, and then change the name to ConfigMgrTSActionControl.cs.

In Solution Explorer, right-click References, and then click Add Reference.

In the Add Reference dialog box, click the Browse tab, navigate to %ProgramFiles%\Microsoft Configuration Manager\AdminUI\bin, and then select the following assemblies:

• Adminui.osdcommon.dll
  
  
• Adminui.tasksequenceeditor.dll
  
  
• Adminui.wqlqueryengine.dll
  
  
• Microsoft.configurationmanagement.exe
  
  
• Microsoft.configurationmanagement.managementprovider.dll
  
  

Click OK to add the assemblies as project references.

In Solution Explorer, right-click ConfigMgrTSActionControl.cs, and then click View Code.

Add the following code to include the required namespaces:

	Copy Code
using Microsoft.ConfigurationManagement.AdminConsole; using Microsoft.ConfigurationManagement.AdminConsole.TaskSequenceEditor;

Change the class ConfigMgrTSActionControl so that it derives from SmsOsdEditorPageControl.

In ConfigMgrTSActionControl.cs, add the following new constructor to the ConfigMgrTSActionControl class:

	Copy Code
public ConfigMgrTSActionControl(SmsPageData data) : base(data) { InitializeComponent(); }

Add the following method to initialize the control:

	Copy Code
public override void InitializePageControl() { base.InitializePageControl(); }

In Solution Explorer, right-click ConfigMgrTSActionControl.cs, and then click View Designer.

In the Toolbox, click the Common Controls tab, and then double-click TextBox. A button named textBox1 is added to your control on the User Control Designer.

Double-click the text box. An event handler named textBox1_TextChanged is added to the class ConfigMgrTSActionControl. Add the following code to ensure that changes are saved to the action's property manager:

	Copy Code
SetDirtyFlag(true);

In the class ConfigMgrTSActionControl, add the following method to write the text box value to the User property defined in the custom action MOF. This is called when the OK or Apply button is clicked.

Copy Code

protected override bool ApplyChanges(out Control errorControl, out bool showError) { // You can check the error here and return false. if (this.HasError(out errorControl) == true) { this.ShowMessageBox( this.GetErrorString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning); errorControl = null; showError = true; return false; } this.PropertyManager["User"].StringValue = textBox1.Text; return base.ApplyChanges(out errorControl, out showError); }

In the design view for the control, double-click the control to create the method ConfigMgrTSActionControl_Load.

Add the following code to the method. This code loads the text box with an existing User value. This happens when the task sequence action is edited after it is created.

	Copy Code
textBox1.Text = this.PropertyManager["User"].StringValue;

In Solution Explorer, on the Project menu, click Properties.

Click the Resources tab. If the resources file does not exist, create it by selecting the message that is displayed on the Resources tab.

On the Resource Designer toolbar, point to the resource view drop-down, click the arrow, and make sure it is set to Strings (which is the default). A settings grid appears, displaying the strings that are maintained by that instance of the Resource Designer.

Click the Name column of the last row in the grid, which is marked with an asterisk (*).

In the Name column, enter DefaultDisplay_ConfigMgrTSAction as the string name.

In the Value column, enter the string Custom Action. This is the string displayed in the list of task sequence actions.

Click the Name column of the last row in the grid, which is marked with an asterisk (*).

In the Name column, enter ConfigMgrTSAction as the string name.

In the Value column, enter Custom Action. This is the string that is displayed when you add the custom action.

Build the project. Visual Studio creates the assembly as \Visual Studio 2005\Projects\ConfigMgrControl\ConfigMgrTSAction\bin\Debug\ConfigMgrTSActionControl.dll.

Copy the assembly to the folder %ProgramFiles%\Microsoft Configuration Manager\AdminUI\bin.
