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
End Function
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
