Auto3Lib

[PaulIA]

Hello! I try to run an example from the auto3lib manual and everytime i get error message:

-------------------------------------

Line 124 (File "C:\Program Files\AutoIt3\Include\A3LListbox.au3"):

$tBuffer.Text = $sText

$tBuffer^ERROR

Error: Variable must be of type "Object"

--------------------------------------

What is wrong here?

Welcome to the forum. You need the latest beta version of AutoIt that includes the new structure changes.

Paul,

How do I get the node handle by using the click mouse (left click). ?

The example "TreeView 1.au3" show how to handle right click but not how to get it by left click.

Can you please show me how do you do that with "TreeView 1.au3"? Thanks !!!

[perrin_goldeneyes]

I'm here so I can answer to you quicker than PaulIA:

You must use latest beta version of AutoIt.

Ok, thanks, I no longer get the error

There's a couple of ways to do this:

1. In the loop where I wait for the $GUI_EVENT_CLOSE message, look for $GUI_EVENT_PRIMARYDOWN too which tells you the primary mouse button was pressed. Then use _TreeView_GetSelection to return the currently selected node.

2. Use GUIRegisterMessage and register the $TVN_SELCHANGED message. This message is sent by the TreeView when the selection changes from one node to another. When you receive this message, use _TreeView_GetSelection to return the currently selected node. If you go this route, you need to comment out the line that registers the $WM_NOTIFY message.

I'll leave the coding to you as an exercise. Just use TreeView 1 as your guide and if you get stuck, let me know.

Paul, I have succeded to run the first option but it is not good solution for me.

It is not since when I click on the toolbar command buttons it is clicked on the selected node tree as well..the $GUI_EVENT_PRIMARYDOWN works for both of them and I did not find solution for it.

(BTW: I merged the "TreeView 1.au3" and "Tolbar 1.au3").

I have tried solution number two without much successful. I would be happy to get help on it.I was not able to get the node handle without using $WM_NOTIFY.

I must have been asleep when I answered this before. The $TVN_SELCHANGED message is sent via $WM_NOTIFY. What I SHOULD have said, is change the WM_NOTIFY handler to trap this message (not delete it). Here's a short piece of code to show you what you need to do. I will include the structure definition in the next release.

Paul, Something is wrong with the string ($tagNMTREEVIEW ) that create the struct. I am getting error # 2.

What's wrong?

Error 2 means that the data type isn't valid. Are you sure you didn't mess up the code when you copied it from the forum? Do you have the latest beta version of AutoIt? Edited April 8, 2007 by PaulIA

Hi,

I'm using Windows XP Pro SP2, AutoIt 3.2.2.0, Scite 1.72 and the Auto3Lib dated 04/04/2007

Bienvenue au forum! (Pardon my French) First, check to make sure you have the latest beta version of AutoIt installed. Next, make sure that when you installed Auto3Lib, that you deleted any old A3L*.au3 files from the include folder. Then, if the problem still exists, tell me which example in the help file that you are getting this error on. Edited April 8, 2007 by PaulIA

I remove AutoLib from AutoIT version

I installaed last beta v3.2.3.2

I re-installed AutoLib in beta version directory

Run in beta version = is OK

Thank You PaulIA

It was my beta synchronization problem

Thank you

Paul,

How do I create clientedge style for the TreeView control.

Something like $WS_EX_CLIENTEDGE in Autoit3?

Thanks

I had a working script Friday, but today I updated Auto3Lib using the new installer and the script now throws an error.

I did a:

del a3l*.au3

in the include directory and then reran the installer and chose "repair" and the problem remains.

I'll try to debug on my side, but can you take a quick look at this issue and see if you can come up with something?

I'll add this capability to the next release, which should be later today or tomorrow depending on how long it takes to finish the regression testing.

[tinjaw]

That's it! PEBCAK I overlooked that that was a requirement. Where can I get the old version of Auto3Lib as I am not using the Beta version of AutoIt?

I don't keep the old versions. You're better off just installing the beta version of AutoIt. I haven't found any problems with it yet and you'll get all the Auto3Lib bug fixes that way.

I have all old versions. So if somebody want, just send me PM.

But as PaulIA said best way is to use latest beta of AutoIt and latest version of Auto3Lib

[tinjaw]

I don't keep the old versions. You're better off just installing the beta version of AutoIt. I haven't found any problems with it yet and you'll get all the Auto3Lib bug fixes that way.

I will take Zedna up on the offer to get the older version and I will also install the Beta version of AutoIt to a separate folder and start to migrate my projects over as time allows.

thanx,
