<p>Well I would like to make a custom run dialog within my program so that the user can test commands without opening it themselves. The only problem is, msdn does not provide any coverage on this. If I cannot make my own custom run dialog and send the data to shell32.dll (where the run dialog is stored) I will settle ... | <p>VBScript's CreateObject() function just creates an instance of a COM object.

| <p>Creating a simple RUn dialog is not a big problem (the user interface). The data entered by the user can be run via <a href="http://msdn.microsoft.com/en-us/library/bb762153(VS.85).aspx" rel="nofollow noreferrer">ShellExecute</a>. If you want to call the Run dialog then you should use COM.</p>

<p>I was getting bad data from an application I was writting using C++ in Visual Studio 2k3 so I decided to debug it. Then I found it was throwing an exception but one I can't track down.</p>
