Tool - How to clear and write text into the log window part?

[highend]

Hi,

is there a small tutorial how to do that?

I would need to clear all lines from that gui part (#GADGET_ErrorLog) on invocation of the tool (one that would be running via menu - tools - configure tools...) and then write (line by line) content into it again...

Thanks!

Writing to the IDE is straightforward with WriteIDELog from here. Deleting the log is a little more tricky. Normally you would just use SendMessage(hWnd_IDE, #LB_RESETCONTENT, 0, 0) to clear the listbox, but PB stores the text lines so that they can be restored on a tab switch. Using WriteIDELog afterwards would just restore the previous text. It is therefore better to call the menu ID for “Clear log” directly and let PB do its thing... If #WM_COMMAND with id 73 doesn't clear the log in your IDE, you have to find the id yourself

Code: Select all

Procedure WriteIDELog(hWnd, text$)
  If hWnd
    Protected CopyData.COPYDATASTRUCT
    CopyData\dwData = ('L' << 16) | ('O' << 8) | 'G'
    CopyData\cbData = StringByteLength(text$, #PB_Ascii)
    CopyData\lpData = AllocateMemory(CopyData\cbData + 1)
    If CopyData\lpData
      PokeS(CopyData\lpData, text$, -1, #PB_Ascii)
      SendMessage_(hWnd, #WM_COPYDATA, #Null, @CopyData)
      FreeMemory(CopyData\lpData)
    EndIf
  EndIf
EndProcedure

hWnd_IDE = Val(GetEnvironmentVariable("PB_TOOL_MainWindow"))

If hWnd_IDE
  SendMessage_(hWnd_IDE, #WM_COMMAND, 73, 0) ;;; Clear the errorlog window. Use spyxx_amd64.exe (Messages) or similar to get the menu id
  WriteIDELog(hWnd_IDE, "Hello, I'm an Errorlog message...")
  WriteIDELog(hWnd_IDE, "... and another one")
EndIf

Thanks a lot chi!

On my system 73 is the correct id for that menu entry as well
Although a solution (from Fred) with a more general approach (a menu id could change in the future and then you can't easily support older and newer guis) to clear the log would be nice

Again, thank you, everything is working as expected atm

Happy to help

About the id: To iterate through all menu items with WinAPI, you can use GetMenu, GetMenuItemCount, GetMenuItemID and GetMenuString. After that it is quite easy to get the id for "Clear log" for past/future PB-IDE's...

Not necessarily

At least not without (a bit of) effort because of different menu languages...

And timing is also crucial. You shouldn't execute that menu entry and immediate write to the log window part again.
At least here the first line is normally lost when I don't use a Sleep_(xxx) after the SendMessage_()

True, to make it more bulletproof, you have to fiddle around a bit
