ControlTreeView GetText doesn't work in C# 64-bit

[MathieuT]

Hi all,

 

While building a program in C# with the inclusion of AutoItX, I discovered an issue with ControlTreeView GetText.

Normally I start testing some AutoIt functionality in AutoIt itself (using SciTE-Lite), before implementing it in my code in C#. There is a SysTreeView32 in the application I'm trying to automate, so did some testing using the ControlTreeView function. The function and all the commands I tried are working perfectly.

Then I moved to C#, everything seems okay until I tried the GetText command. This always returns an empty string and it sets the AutoItX.ErrorCode() to 1.

 

So I did some more testing in AutoIt, executing the GetText command in SciTE-Lite and AutoIt3.exe works perfectly, but it doesn't in AutoIt3_x64.exe.

So apparently the GetText command doesn't work when executing the AutoIt code as 64-bit. Obviously, my C# program is also 64-bit and the AutoItX source code checks for 32 or 64-bit and then executes the corresponding code (AU3_ControlTreeView64 vs AU3_ControlTreeView32).

If it matters, the application that contains the SysTreeView32 is 32-bit.

 

Forgive me if it is a stupid question, but is it possible to get the GetText command working without changing my C# program to 32-bit?

Thank you in advance.

What version of AutoIt(X) are you using? It works correctly for me using AutoIt 3.3.16.1 in both 32 bit and 64 bit. Show us the script you are using for testing if you still can't make it work.

I'm also using AutoIt 3.3.16.1.

This is the code I tested in AutoIt, this prints the first first three levels of the TreeView to the console (I know the code can be cleaner and shorter 😛). I added the message box to get some feedback while running the script using AutoIt3.exe and AutoIt3_x64.exe. As I said earlier, it works in SciTE-Lite and AutoIt3.exe, but not in AutoIt3_x64.exe.

The other commands work fine in SciTE-Lite, AutoIt3.exe and AutoIt3_x64.exe.

Some examples I use in C#:

AutoItX.ControlTreeView(windowHandle, treeviewHandle, "Select", currentTreeViewItem, ""); // works as expected
int count = int.Parse(AutoItX.ControlTreeView(windowHandle, treeviewHandle, "GetItemCount", currentTreeViewItem, "")); // works as expected

string treeviewItemText = AutoItX.ControlTreeView(windowHandle, treeviewHandle, "GetText", treeviewPosition, ""); // doesn't work as expected, returns an empty string

I also tried the alternative function which takes "string title, string text, string control..." instead of "IntPtr winHandle, IntPtr controlHandle...".

I was hoping that you would post a short snippet of code that demonstrated your claim that GetText fails in 64 bit mode. FWIW, my previous tests were performed with a modified version of the help file example for ControlTreeView.

Thank you for the suggestion.

 

I used the help file example for ControlTreeView and made the following script to manipulate the TreeView created in the ControlTreeView example.

Example()

Func Example()
    Local $hGUI = WinGetHandle("ControlTreeView Example")
        Local $hTreeView_1 = ControlGetHandle($hGUI, "", "[CLASS:SysTreeView32; INSTANCE:1]")   
    WinActivate($hGUI)
    
    ControlTreeView($hGUI, "", $hTreeView_1, "Collapse", "Root|Item 4")
        
EndFunc   ;==>Example

 

When both scripts are run in the same mode, Item 4 is collapsed. If one is run in 32-bit and the other in 64-bit Item 4 is not collapsed. Repeat for other commands.

It is strange that none of the ControlTreeView commands are working when mixing 32-bit and 64-bit. Because using AutoItX in C# (64-bit), I'm able to use most of the commands on a TreeView in a 32-bit application. Except of course the GetText command.
