webbrowser

thanks everyone, but now I have a new problem.. this program I'm making runs in the background (with me.hide), so sendkeys wouldn't work..

I searched the forum and found some code but can't get it to work

Code:

---

Private Sub Timer1_Timer()
  opendialog = FindWindow(vbNullString, "Choose file")
  If opendialog > 0 Then
    hEdit = FindWindowEx(opendialog, 0&, "Edit", vbNullString)
    Call SendMessage(hEdit, WM_SETTEXT, 0&, "C:\test.txt")
    Timer1.Enabled = False
  End If
End Sub

---

I also downloaded winspy++ to check if the name of the editbox was "Edit" and I'm pretty sure it is

But you wouldn't send the messages to the Edit window. You would send them to the Choose file window.

Code:

---

Private Sub Timer1_Timer()
  opendialog = FindWindow(vbNullString, "Choose file")
  If opendialog > 0 Then
    SendMessage opendialog, WM_SETTEXT, 0&, "C:\test.txt"
    Timer1.Enabled = False
  End If
End Sub

---

Edit: Also, have you declared WM_SETTEXT?

I don't think that's right.. you can't just send WM_SETTEXT to the choose file window
what if it had multiple editboxes? it woudn't know which one to type in
I tried your code and it didn't work

And yes, at the top I have

Code:

---

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, _
ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _
lParam As Any) As Long
Private Const WM_SETTEXT = &HC

Well, I am on holiday today (Monday) and will have check some code back at the office on Tuesday. Or maybe someone will cover it before me.

It's a lot more complicated. FindWindowEx can only find children directly under the window you're looking in. The Edit control isn't a first child. The actual hierarchy (from Windows XP and IE7's open dialog) goes:

#32770 "Choose file:"
ComboBoxEx32 ""
ComboBox ""
Edit ""

So you have to look in that order:

Code:

---

Private Sub Timer1_Timer()
  Dim opendialog As Long
  Dim hEdit As Long
  Dim hCombo As Long
  opendialog = FindWindow(vbNullString, "Choose file")
  If opendialog > 0 Then
    Do
      hCombo = FindWindowEx(opendialog, 0&, "ComboBoxEx32", vbNullString)
      If hCombo > 0 Then hCombo = FindWindowEx(hCombo, 0&, "ComboBox", vbNullString)
      If hCombo > 0 Then hEdit = FindWindowEx(hCombo, 0&, "Edit", vbNullString)
    Loop While hEdit = 0
    Call SendMessage(hEdit, WM_SETTEXT, 0&, ByVal "C:\test.txt")
    Timer1.Enabled = False
  End If
End Sub

---

You also have to pass the string ByVal or else it gets chewed up when it actually goes in to the text field.

This code could be improved upon, as there are a few potential pitfalls. And the open dialogs could be different depending on the application (not as likely) and the version of Windows (much more likely).

thanks, that worked. but now I can't figure out how to press enter!

Code:

---

        Call SendMessage(hEdit, WM_SETTEXT, 0&, ByVal "C:\test.txt")
        Call SendMessage(hEdit, WM_LBUTTONDOWN, VK_RETURN, 0)
        Call SendMessage(hEdit, WM_LBUTTONUP, VK_RETURN, 0)

it looks pretty simple.. but I can't figure out why it won't work
I even tried postmessage

WM_LBUTTONDOWN
The WM_LBUTTONDOWN message is posted when the user presses the left mouse button while the cursor is in the client area of a window.

---

Can't exactly replicate pressing Enter with a mouse click on an edit box.

I tried WM_KEYDOWN and WM_KEYUP in it's place, but the dialog wouldn't dismiss. You may just have to find the Open button and send the WM_LBUTTONDOWN and WM_LBUTTONUP to simulate a click on it.

I got it to close using the Open button.. but now I'm trying to figure out how to know when it's finished uploading

I don't think the page reloads or anything, they just use javascript to change part of the page and show you your download url (I think..)

I thought about using a timer to check when the length of downloadurl > 0, but I can't seem to access WebBrowser1 from my timer, or anything outside WebBrowser1_DocumentComplete

I used WebBrowser1.Document.getElementById("downloadurl").Value

At this point, you'll just have to see how it acts when you do an upload and see if the page redirects or just updates something on the page.

If it does redirect, you can use DocumentComplete (at this point, you'd have to have it check the URL to know whether it should do an upload or read the results), if it doesn't, you'll have to watch some object on the page for what you're waiting for.

does anyone have any ideas? I need it to close when it's done uploading
the page doesn't redirect to anything..
