Hello:

I am trying to use toolbar buttons to open the Folder dialog box. I have tried using value from $iItem to initiate the fileselectfolder. The problem starts after I close the folderdialog box. Clicking anywhere on the Toolbar even where there are no controls initiates the folderdialog box.

Could someone help me with a way out or an alternative to my method. I have posted the script from helpfile as it is.

Please help.

Regards

Ajit

Hi:

I have posted my modified code. It is a single line to initiate fileselectfolder dialog box.

Please see that after closing the dialog box clicking anywhere on the Toolbar "line" initiates the fileselectfolder dialog box.

ajit,

Major problem with your code. Did you not read the Remarks section under GUIRegisterMsg? :P

"Warning: blocking of running user functions which executes window messages with commands such as "Msgbox()" can lead to unexpected behavior, the return to the system should be as fast as possible !!!"

FileSelectFolder is a blocking function - so it is hardly surprising that you are getting weird results after blocking the Windows message stream. Try using a flag like this - then you return quickly from the message handler and the problem goes away: :party:

Melba, could you explain this

Warning: blocking of running user functions which executes window messages with commands such as "Msgbox()" can lead to unexpected behavior, the return to the system should be as fast as possible !!!

more detailed? (Just for learning purposes... I don't quite understand it... Thank you in advance!) Edited by taietel

Things you should know first...In the beginning there was only ONE! And zero...

Please read my post above - you still have a blocking function within the message handler! :mellow:

taietel,

This is an extract from the tutorial I wrote about GUIRegisterMsg in the Wiki:

"Windows works by sending messages to everything on the system, so that everything knows what is going on. By messages, I mean things like the $GUI_EVENT_CLOSE we look for when we exit a GUI - but the possible range is much, much wider; change of focus, change of state, mouseclicks, mousemoves, key presses, etc, etc, etc.

GUIRegisterMsg allows us to intercept certain of these messages as they are sent by the GUIs we have created, so we can see who sent what. So when you see a GUIRegisterMsg($WM_COMMAND, "MY_WM_COMMAND") line in a script, this translates as "Whenever a WM_COMMAND message is sent by my GUI, please intercept it and pass it through the MY_WM_COMMAND function in this script". The actual message title is denoted by the constant $WM_COMMAND which is stored in WindowsConstant.au3 include file. Of course, you can use other message types as well (such as $WM_NOTIFY) - and call your function whatever you wish!

[...]

Now, what about the use of a flag in the second example? Well, if you read the Help file for GUIRegisterMsg you will see the following:

"Warning: blocking of running user functions which execute Windows messages with commands such as "Msgbox()" can lead to unexpected behavior, the return to the system should be as fast as possible !!!"

Basically, if you spend too long in your message handling function, the rest of the system gets behind and becomes unstable. So you should get out of it as quickly as you can - and certainly never create anything that waits for user input. If you set a flag as in the second example you can then check for the flag in your While...WEnd loop, or via an Adlib function, and then run your long and complicated function without blocking the rest of the system."

Does that help?
