C# Signature:

[DllImport("shell32.dll")]
static extern IntPtr FindExecutable(string lpFile, string lpDirectory, [Out] StringBuilder lpResult);

VB Signature:

<DllImport("shell32.dll")> _
Private Shared Function FindExecutable(ByVal lpFile As String, ByVal lpDirectory As String, ByRef lpResult As StringBuilder) As IntPtr
Private Shared Function FindExecutable(ByVal lpFile As String, ByVal lpDirectory As String, <Out()> ByVal lpResult As StringBuilder) As IntPtr
End Function

VBA Signature:

Private Declare Function FindExecute Lib "shell32.dll" Alias _
"FindExecutableA" (ByVal lpFile As String, ByVal lpDirectory _
As String, ByVal lpResult As String) As Long

User-Defined Types:

None.

Notes:

1) When using VB, one cannot place the declaration for FindExecutable within

the code portion of a form. If one needs to search for an executable from

within a form, though, it is easy enough to open a module and place the

declaration there. From the form code, make a call to a function in the

module. Within the module function, execute FindExecutable and return any

results to the form routine. steveapub@pineclifftech.com

2) Make sure the following references are available:

Imports System.Runtime.InteropServices
Imports System.Text

Tips & Tricks:

Error Codes that can be returned:

    Public Enum FindExecutableErrorCodes
    ''' <summary>The specified file was not found.</summary>
    SE_ERR_FNF = 2

    ''' <summary>There is no application associated with the given file name extension. This error will also be returned if you attempt to print a file that is not printable. </summary>
    SE_ERR_NOASSOC = 31

    ''' <summary>There was not enough memory to complete the operation.</summary>
    SE_ERR_OOM = 8
    End Enum
