Steps to Reproduce Behavior
Start a new Standard EXE project. Form1 is created by default. Add the following code:
Public Sub AddURL(ByVal sURL As String, _ Optional ByVal sTitle As String = "", _ Optional ByVal sSize As String = "", _ Optional ByVal lSizeUnit As Long = 0) inetDownload.Execute sURL, "GET" End Sub
- From the Project menu, click Components, and select the Internet Transfer Control 5.0 into the project if it is not already loaded.
Place an Internet Transfer Control 5.0 (Inet1) on Form1 and add the following code:
Private Sub Inet1_StateChanged(ByVal State As Integer) Const lCHUNKSIZE As Long = 1024 Dim vtData As Variant ' Data variable. Select Case State ' ... Other cases not shown. Case icError ' 11 ' In case of error, return ResponseCode and ' ResponseInfo. vtData = Inet1.ResponseCode & ":" & _ Inet1.ResponseInfo Case icResponseCompleted ' 12 Dim strData As String: strData = "" Dim bDone As Boolean: bDone = False ' Get first chunk. vtData = Inet1.GetChunk(lCHUNKSIZE, icString) DoEvents Do While Not bDone strData = strData & vtData ' Get next chunk. vtData = Inet1.GetChunk(lCHUNKSIZE, icString) DoEvents If Len(vtData) = 0 Then bDone = True End If Loop Case icDisconnected Debug.Print "* Disconnected" Unload Me End Select End Sub
Add another form to your project. By default, it will be called Form2. IMPORTANT: Make Form2 your startup form by changing the properties of the project. Add the following code:
Private Sub Form_Load() Load form1 End Sub Private Sub Form_Unload(Cancel As Integer) Unload form1 End Sub
Place a CommandButton (Command1) on Form2 and add the following code:
Private Sub Command1_Click() form1.AddURL "http://www.microsoft.com" End Sub
- From the Run menu, click Start (ALT, R, S), or press the F5 key to run the program. Click the Command1 button and you will see error described above.
