KB190502 - PRB: Missing Files Dialog Box Appears When Running PDW

CAUSE

The Package and Deployment Wizard scans a project's files for Declare statements to determine if any additional dependency files need to be distributed. If any such files are not found, the user is prompted for the location of the files with the "Missing Files" dialog box.

If any declarations for 16-bit DLLs are found in the project's files, the user is prompted for the location. For example, if the following 16-bit declaration appears in the project the PDW will prompt the user for the location of the Kernel DLL:

   Declare Function GetWindowsDirectory Lib "Kernel" _
      (ByVal lpBuffer As String, ByVal nSize As Integer) As Integer

This is a very common problem with applications converted from 16-bit Visual Basic to Visual Basic 5.0 or 6.0, or with Visual Basic 4.0 applications that use conditional compilations that have been converted to Visual Basic 5.0 or 6.0. The PDW does not take into consideration the compiler directives when looking for Declare statements, as in the following example:

   #If Win32 Then
      Declare Function GetWindowsDirectory Lib "Kernel32" _
         Alias "GetWindowsDirectoryA" _
         (ByVal lpBuffer As String, ByVal nSize As Long) As Long
   #Else
      Declare Function GetWindowsDirectory Lib "Kernel" _
         (ByVal lpBuffer As String, ByVal nSize As Integer) As Integer
   #End If

Steps to Reproduce Behavior

Create a new Standard EXE project in Visual Basic. Form1 is created by default.

Add a new module (Module1) to the project.

In the General Declarations section of Module1, add following code:

      #If Win32 Then
         Declare Function GetWindowsDirectory Lib "Kernel32" _
            Alias "GetWindowsDirectoryA" _
            (ByVal lpBuffer As String, ByVal nSize As Long) As Long
      #Else
         Declare Function GetWindowsDirectory Lib "Kernel" _
            (ByVal lpBuffer As String, ByVal nSize As Integer) As Integer
      #End If

Save the project, compile it, and then exit Visual Basic.

Start the Package and Deployment Wizard and proceed to the form entitled "Package and Deployment Wizard - Package Folder." Select a folder and click the Next button. Note that a dialog box entitled "Missing Files" is displayed, with Kernel.Dll in the list of missing files.
