Introduction Hi Friends, Today morning I need to create an application which is build in VB 6.0 and I wanted to open another VBP file from my existing project. I Googled it a lot but couldn't found anything, however I managed to achieve it anyhow, so this would be helpful to you also. Background On Button Click, It will open a new VBP Project. The code Code: VB 6.0 Code: 'in General-Declarations: Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" ( _ ByVal hWnd As Long, _ ByVal lpOperation As String, _ ByVal lpFile As String, _ ByVal lpParameters As String, _ ByVal lpDirectory As String, _ ByVal nShowCmd As Long) As Long Private Sub Form_Load() 'open a file ShellExecute Me.hWnd, "open", "C:\Test1.vbp", vbNullString, "C:\", ByVal 1& End Sub Private Sub OpenAFile(strFileLocation As String) 'Just call the OpenAFile sub with the path of the file to open as its parameter. If Dir$(strFileLocation) = "" Then Exit Sub End If ShellExecute Me.hWnd, "open", strFileLocation, vbNullString, "C:\", ByVal 1& 'Example code (same effect as the examples above) Call OpenAFile("C:\Test1.vbp") End Sub Private Sub Command1_Click() OpenAFile ("C:\Test1.vbp") End Sub Thanks
