Quickly enter command-line parameters for Visual Studio debugging?

Macro below should help. Open "Tools->Macros->Macro Explorer", then create new module, edit it, and copy-paste code below. Required command is SetCommandArgsProperty. UI is not nice, but it works (VS 2005, I hope this will also work in VS 2010). Then add any shortcut you like to run this macro.

Here are some details:

• Find startup project
• Select it active configuration and find property with name "CommandArguments"
• Create edit box with the current value in it

• Update property if OK is selected

  Sub SetCommandArgsProperty()
      Dim newVal As Object
      newVal = InputValue(GetCommandArgsPropertyValue())
      If TypeOf newVal Is String Then
          SetCommandArgsProperty(newVal)
      End If
  End Sub
  
  Function InputValue(ByVal defaultText As String)
      Dim frm As New System.Windows.Forms.Form
      Dim btn As New System.Windows.Forms.Button
      Dim edit As New System.Windows.Forms.TextBox
  
      edit.Text = defaultText
      edit.Width = 100
  
      btn.Text = "OK"
      btn.DialogResult = System.Windows.Forms.DialogResult.OK
  
      frm.Text = "Input command line properties"
  
      frm.Controls.Add(btn)
      btn.Dock = System.Windows.Forms.DockStyle.Bottom
  
      frm.Controls.Add(edit)
      edit.Dock = System.Windows.Forms.DockStyle.Top
  
      frm.Height = 80
      frm.Width = 300
  
      If frm.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
          Return edit.Text
      End If
      Return System.DBNull.Value
  End Function
  
  Function GetCommandArgsProperty() As EnvDTE.Property
      Dim solution As Solution
      Dim project As Project
      Dim sb As SolutionBuild
      Dim str As String
      Dim cm As ConfigurationManager
      Dim config As Configuration
      Dim properties As Properties
      Dim prop As EnvDTE.Property
  
      solution = DTE.Solution
      sb = solution.SolutionBuild
      For Each str In sb.StartupProjects
          project = solution.Item(str)
          cm = project.ConfigurationManager
          config = cm.ActiveConfiguration
          properties = config.Properties
          For Each prop In properties
              If prop.Name = "CommandArguments" Then
                  Return prop
              End If
          Next
      Next
  End Function
  
  Function GetCommandArgsPropertyValue()
      Return GetCommandArgsProperty().Value
  End Function
  
  Sub SetCommandArgsProperty(ByVal value As String)
      GetCommandArgsProperty().Value = value
  End Sub
  

The extension CLIArgsMadeEasy 2010/2012 is a great little thing that puts the project's debug session's command line arguments right in a little text box on the visual studio toolbar, IMO, its alot easier and less tedious than using macros.

You can just type CLIArgsMadeEasy in your search box in the extensions manager which will find it fairly quickly in the gallery, thats how I installed it, if you need to know. Hope this helps!
