  1. Program to solve for variable algebraically eg: v=u+a*t -> a=(v-u)/t

    I would like to make a program which solves for an unknown in an equation, which seems easy to do on paper, but I have no idea how to make the computer do it.
    Here's an example: I start with a...
  2. Re: [RESOLVED] Can you use sendmessage to change datepicker value in external app?

    I've just realised that I got type mismatch because i used both " and # now it's ok. Although it assumes the date is in American format when I put it this way:

    Disable printing of another/all workbooks

    I can use this code to disable printing on a macro eanabled workbook:


    Private Sub workbook_BeforePrint(Cancel As Boolean)
    Cancel = True
    MsgBox "You cannot print this workbook"
    End Sub

  5. Re: [RESOLVED] Can you use sendmessage to change datepicker value in external app?

    I got type mismatch after putting "#".

    I may have done it incorrectly, but changing LT to ST didn't work for me. In excel 0 = 00/01/1900, and I know in some systems 0 = 30/12/1899. Assuming mine...
  6. Re: Can you use sendmessage to change datepicker value in external app?

    I'm sorry I didn't read your post properly. When I looked at DTM_SETSYSTEMTIME I assumed it only changes the system time. Since then I tried and it worked, without the reliability issues associated...
  7. Re: Can you use sendmessage to change datepicker value in external app?

    Changing system time doesn't work this time as this program doesn't get it's date from windows. The handle is "ctrl1". This one didn't work:


    Call SendMessage(ctrl1, WM_SETTEXT, 0&, "01/01/2010")...
  8. [RESOLVED] Can you use sendmessage to change datepicker value in external app?

    You may be right about bringing it to the top. About not finding the handle I was not completely clear. Knowing the handle of the main window is enough for simulating mouse click with mouse_event (I...
  10. simulate mouse click when the target window is in background

    I've been doing a lot of automation lately. In some cases I can't avoid using simulated mouse clicks. Unfortunately at my workplace there are programs which randomly pop up to steal the focus and...
  11. Re: If a program was made in VB, is there an easier way of controlling it with macros

    Thanks for the info. I'll just continue with what I've been doing so far. I believe that being able to send controls to other applications is useful anyway.

  13. [RESOLVED] If a program was made in VB, is there an easier way of controlling it with macros?

    I suspect that this program was made in VB because there are ThunderRT6 classnames in it. Eg.: instead of Class: Button, it has Class: ThunderRT6CommandButton. Once it has also returned an error...

    Thanks. After ticking "Trust access to the VBA project object model" in the macro settings of the trust center I learned what I wanted. (it was 7.00)

  22. Re: Event doesn't fire when filling external combobox with sendmessage, only text cha

    I used sendmessage to double-click on the combobox, which fires the Click event. I'm sure this is not the "official" solution, but it works and I believe it's reliable.

    On the cmb.text line I get the "Variable not defined." error. If I leave that part out the code does the same as it used to.
  24. Re: Event doesn't fire when filling external combobox with sendmessage, only text cha

    I changed the variable name from "combobox", and &O0 to 0&. The result is still the same. If I put .hwnd after the variable name in sendmessage I get "Invalid Qualifier" error.
