BUG: Visual C++ .NET Custom Wizard [!loop=n] directive crashes Visual Studio .NET (810304)

[!loop = n]
...
[!endloop]

[!loop = symbol]
...
[!endloop]

MORE INFORMATION

Wizards that are based on the Visual Studio .NET wizard engine, such as those produced by the Visual C++ .NET Custom Wizard, recognize a template directive loop as follows:.

[!loop = n]
...
[!endloop]

When n is a literal number, the directive causes Visual Studio .NET to crash. The crash occurs during project or code generation when the directive is encountered in a template file.

How to Specify the Loop Counter

As an alternative method to specify the loop counter, define a symbol with a numeric value and then use this symbol in the loop directive. The numeric value indicates the number of loops the wizard executes.

The following examples provide three ways to define the symbol named NUM_LOOPS with a numeric value 5. The numeric value 5 is the number of loops to be executed.

• In the OnFinish function located in the Default.htm file, use the AddSymbol function to add a symbol with an appropriate value:

  function OnFinish(document)
  	{
  		window.external.AddSymbol("NUM_LOOPS", 5);
  		OnWizFinish(document);
  	}

• In the OnFinish function located in the Default.js file, use the AddSymbol function to add a symbol with an appropriate value:

  function OnFinish(selProj, selObj)
  {
  	try
  	{
  		var strProjectPath = wizard.FindSymbol('PROJECT_PATH');
  		var strProjectName = wizard.FindSymbol('PROJECT_NAME');
  
  		wizard.AddSymbol("NUM_LOOPS", 5);
  		...
  	}
  	...
  }

  For more information about the VCWizCtl object and its AddSymbol method, see the "References" section.
• In the template file (such as Templates.inf or a template specified in Templates.inf), create a symbol using the syntax [!symbol = n], where symbol is the symbol name used to control the loop and n is the number of loops to process:

  [!NUM_LOOPS = 5]
  
  

  Note: The directive [!symbol = n] is currently undocumented.

The loop directive can now be specified with the NUM_LOOPS symbol, instead of a numeric value:

[!loop = NUM_LOOPS]
...
[!endloop]
