FindWindowEx Windows API returns nothing in AutoIt - autoit

I'm using the following code to return handle for a open file dialog box shown from Notepad.
Global $Result = DllCall("User32.dll", "HWND", "FindWindowExA", "HWND", WinGetHandle("[CLASS:Notepad]"), "HWND", Null, "STR", "#32770", "STR", "Open")
ConsoleWrite("FindWindowEx Return Value: " & String($Result[0]) & #CRLF)
This always returns 0x00000000, but given parameters seems correct.
Why does this function return nothing here?
UPDATE
The following syntax worked, but I still can't specify the parent window:
Global $Result = DllCall('User32.dll', 'HWND', 'FindWindowExW', 'HWND', Null, 'HWND', Null, 'WSTR', '#32770', 'WSTR', 'Open')
This finds every dialog box (Paint, WordPad etc.) , but I only want to get the handle to dialog box with parent as Notepad.

There is no single API to restrict the search to just Notepad. You will have to enumerate all available #32770 windows, looking for ones that belong to a Notepad process, until you find the one you are looking for.
To enumerate the windows, you can use either:
EnumWindows(), filtering in the callback function using GetClassName() and GetWindowText().
FindWindowEx() in a loop, initially setting hwndParent=0 and hwndChildAfter=0, and then setting hwndChildAfter to the last found window on each subsequent call.
To test if a given window belongs to Notepad, you can:
use GetWindowThreadProcessId() to get the window's owning process ID.
then use OpenProcess() to open a handle to the process.
then use GetModuleFileNameEx(), GetProcessImageFileName(), or QueryFullProcessImageName() to retrieve the path and filename of the EXE that created the process.
check if the filename is notepad.exe and the path is the Windows system folder.

What's wrong here?
Open notepad.exe first, type some text without saving, attempt to close notepad but leave resulting dialog (CLASS:#32770, asking so save) opened. Example, as per documentation (untested, no error-checking):
Global Const $g_sWnd = '[TITLE:Notepad; CLASS:#32770; INSTANCE:1]'
Global Const $g_hWnd = WinGetHandle($g_sWnd)
ConsoleWrite($g_hWnd & #CRLF)
Change TITLE:Notepad as required (to notepad's file-open dialog-box title).

Maxscript, backburner rendering renderElements

I have made a script that takes files from directory, and sends them to backburner for network rendering. When I run the script it renders fine but without the render elements they dont show in the backburner monitor nor do they save.
If I open some of the files manualy and send them to render with backburner it works fine, but not with the script?
The render element is VrayAlpha, but I dont think it matters.
This is the code Im using
on btnRender pressed do
(
outputFilesDir = textModelsOut.text + "*.max"
toRender = getFiles outputFilesDir
man = NetRender.GetManager()
man.connect #automatic "255.255.255.0"
man.GetControl()
for s in toRender do
(
renderModelPath = getFilenamePath s + filenameFromPath s
job = man.newJob file:renderModelPath
job.Submit()
)
man.Disconnect()
)
And this is quote from maxscript documentation, it says that render element data will not be available but it will be processed.
Jobs can not have maps included, and render element data will not be
available for submitted job but render elements will process
correctly. These problems are resent when submitting a job from a
file, but not when submitting the current scene.
Anyways my solution was to use job.newJob() to open each scene and submit the current scene.
You should always include your code (or at least some of it) so that we can check it for issues and test it our selves.
However, I usually use a struct called NetRenderAutomation, developed by Gravey.
You can find it here:
http://forums.cgsociety.org/showthread.php?f=98&t=1059510&page=1&pp=15
I haven't had any problems with it, and it is fairly easy to use, and you are even allowed to modify it, if you need some special features for your self.
Hope you can use the answer.
Else feel free to post some code, and I'll look into it.

Set default language for new files

Newly created files in Atom are always "Plain Text". How can I change this so that new files will automatically be in another language, for example "Shell Script (Bash)"? I want to do this because auto indentation does not work with Plain Text files.
Had this problem as well, there is a plugin called default-language that will do this for you.
Search atom for default-language, install and open its settings. Type the name of the language you want Atom to default to, e.g. Shell Script (if in doubt, copy from the language selection menu) in the Default Language field. Next time you open a script with no extension (or shebang) it'll default to the language you set.
The following code, added to your init.coffee, will do what you're asking:
atom.workspace.observeTextEditors (editor) ->
default_scope = 'source.shell'
original = editor.getGrammar()
# If the editor has "null" grammar (aka unset)
if original? and original is atom.grammars.grammarForScopeName('text.plain.null-grammar')
default_grammar = atom.grammars.grammarForScopeName(default_scope)
if default_grammar? # check if desired grammar is already loaded
editor.setGrammar(default_grammar)
else
# grammar was not loaded yet, so add a callback as grammars load
callback = atom.grammars.onDidAddGrammar (grammar) ->
if grammar.id is default_scope
# once we've loaded the grammar, set it and dispose of the callback
editor.setGrammar(grammar)
callback.dispose()
Things to note:
The init.coffee file is where you can customize Atom without having to write a package
The observeTextEditors method sets a callback that is called upon each TextEditor creation for currently open and future editors
The code above:
Checks the grammar that the editor was created with
If and only if it is the default ("null") grammar, it sets the editor's grammar to the Shell grammar once it's loaded
Disposes of the callback to check for grammar loading once it's done with it
This should solve the TypeError: Cannot call method 'getScore' of undefined that happens for the first file opened in a new window.
To default to a different grammar, just change the default_scope = 'source.shell' line to use the scope of whatever grammar you'd like.
Firstly, CTRL+SHIFT+L is your friend. It's unfortunately not a permanent solution, but nice to know about.
Of course, we'd prefer a more permanent solution. A couple of the other answers are now obsolete due to API changes in Atom. Below is a more up-to-date version. Inspiration initially came from this discussion, but the other answers here seem to follow the same concept as well.
Place this in your init.coffee file (File -> Open Your Init Script):
extname = require("path").extname
fileTypes =
".wxs": "text.xml"
".wxi": "text.xml"
".wixobj": "text.xml"
nullGrammar = atom.grammars.selectGrammar("text.plain.null-grammar")
atom.workspace.observeTextEditors (editor) ->
grammar = atom.grammars.selectGrammar(fileTypes[extname(editor.getPath())])
editor.setGrammar grammar if editor.getGrammar() is nullGrammar and grammar isnt nullGrammar
Basically, you define have an array of file types, and the grammars (AKA syntax highlighting) that you want to associate them with. Find each editor, find out if it has a selected grammar already, and if not, attempt to give it one if we find one.
The one issue I've had with this is that the syntax highlighting only works if you open files after you've already launched Atom; if you open a file that results in Atom launching (say by double clicking on it's icon in your favourite OS), syntax highlighting won't for that file until you re-open it.
You need to create a mapping in your config.cson file.
"*":
core:
customFileTypes:
"source.shell": [
"sh"
"shell"
]
For mapping .sh and .shell files to shell script syntax.
Have a look at this bit of code: (you can can then change 'text.html.basic' to whichever syntax you require)
editor = atom.workspace.getActiveTextEditor()
cursor = editor.getLastCursor()
valueAtCursor = atom.config.get(cursor.getScopeDescriptor(), 'my-package.my-setting')
valueForLanguage = atom.config.get(editor.getRootScopeDescriptor('text.html.basic'), 'my-package.my-setting')

How to type text on text fields and click on a button using AutoIt

I have a JNLP file (say Test.jnlp). I have opened that file using AutoIt. My code for opening Test.jnlp file:
$d = "D:\Ripon\"
$f = "Test.jnlp"
Run("cmd /c " & " """ & $d & $f & """ ", "", #SW_HIDE)
After opening .jnlp file a Login screen comes. My requirement is to type Username and Password -> Click Login button.
As I couldn't find the identity of elements (text fields, button) I failed to do that. Please help me.
There are a few types of GUI that don't give you ids for controls, almost all Java toolkits are an example of that.
There are several methods of automating them still:
Assuming the window is always the same size (which is often a pretty safe assumption to make) then AutoIt will allow you to click the window at a given position, or send text just to that window. For example in the above case you could try the following code:
ControlSend("Window Title", "", "", "MyUsername{TAB}MyPassword{ENTER}")
Another solution is using accessibility features. If you google 'autoit java accessibility bridge' I'm sure you'll get some results like this one. I've never tried this personally.
There is also a java access bridge no idea how this works either, but other people have been using it for a while.
As a last resort, you have to mimic user mouse and keyboard actions. This really isn't the best solution but at least you can be very sure it will work.
The following snippet of code should work:
Send("username")
Send("{TAB}")
Send("password")
Send("{ENTER}")

How to Right click of File in Windows Explorer by AutoIt

I wish to simulate a right click on a file. This is done by opening a Windows Explorer window and then right clicking on it.
The main issue is finding the location of the file in Windows Explorer. I am currently using Autoit v3.3.8.1.
My code 's first line:
RunWait (EXPLORER.EXE /n,/e,/select,<filepath>)
The next step is the problem. Finding the coordinates of the file.
After that, right clicking at that coordinates (it seems to me at this time) is not a problem....
Some background:
OS: Windows 7 64-bit
Software Languages: C#, Autoit (for scripting)
The Autoit script is called by a code similar to that below:
Process p = new Process();
p.StartInfo.FileName = "AutoItScript.exe";
p.StartInfo.UseShellExecute = false;
p.Start();
The code is compiled into a console class file which is run at startup. The autoit script runs as the explorer window opens up.
It seems as though you are taking the wrong approach to the problem, so I'll answer what you are asking and what you should be asking.
First up though, that line of code is not valid, and is not what you want either. You want to automate the explorer window, and RunWait waits for the program to finish. Furthermore you want those items to be strings, that code would never work.
Finding the item in explorer
The explorer window is just a listview, and so you can use normal listview messages to find the coordinates of an item. This is done most simply by AutoIt's GUIListView library:
#include<GUIListView.au3>
Local $filepath = "D:\test.txt"
Local $iPid = Run("explorer.exe /n,/e,/select," & $filepath)
ProcessWait($iPid)
Sleep(1000)
Local $hList = ControlGetHandle("[CLASS:CabinetWClass]", "", "[CLASS:SysListView32; INSTANCE:1]")
Local $aClient = WinGetPos($hList)
Local $aPos = _GUICtrlListView_GetItemPosition($hList, _GUICtrlListView_GetSelectedIndices($hList))
MouseClick("Right", $aClient[0] + $aPos[0] + 4, $aClient[1] + $aPos[1] + 4)
As has already been mentioned, sending the menu key is definitely a better way than having to move the mouse.
Executing a subitem directly
This is how it should be done. Ideally you should never need an explorer window open at all, and everything can be automated in the background. This should always be what you aim to achieve, as AutoIt is more than capable in most cases. It all depends on what item you want to click. If it is one of the first few items for opening the file in various programs, then it is as simple as either:
Using ShellExecute, setting the verb parameter to whatever it is you want to do.
Checking the registry to find the exact command line used by the program. For this you will need to look under HKCR\.ext where ext is the file extension, the default value will be the name of another key in HKCR which has the actions and icon associated with the filetype. This is pretty well documented online, so google it.
If the action is not one of the program actions (so is built into explorer) then it is a little more complex. Usually the best way will be to look at task manager when you start the program and see what it runs. Other things can be found online, for example (un)zipping. Actions like copy, delete, rename, create shortcut, send to... They can all be done directly from AutoIt with the various File* functions.
With more information, it would be possible to give you more specific help.
First, you might want to look at the Microsoft Active Accessibility SDK. In particular look at this interface...
http://msdn.microsoft.com/en-us/library/accessibility.iaccessible.aspx
You can use this to walk the items in the control and find the one with the file name you are looking for and its screen location.
From there, maybe try something like this for simulating the right click.
How can I use automation to right-click with a mouse in Windows 7?
Once you have done the right click, use accessibility again to find the right option on the context menu.
Maybe there's an easier way, you should be able to cobble something together like this if you don't find one. Good luck!
Suppose I have a file named test.txt on D drive. It needs to right click for opening Context Menu. To do this, the following code should work:
Local $filepath = "D:\test.txt"
Local $iPid = Run("explorer.exe /n,/e,/select," & $filepath)
ProcessWait($iPid)
Sleep(1000)
Send('+{F10}')

Opening a file using AutoIt

I am using an AutoIt script to automate my application. Following is the command which I am running:
FileOpenDialog ("File Upload", "C:\Documents and Settings\abhishek.kumar\Desktop\Quadrillion work", "Images (*.jpg;*.bmp)", "","WESTF12433.jpg","" )
Send("{ENTER}")
The first command works as it opens up the file open dialog with WESTF12433.jpg file as selected. Now I want to click on open button. How can I do it?
Send("{ENTER}") is not working.
Send is not a good method as it requires the window to be focused, which you can't guarantee. From what you have posted, I would say the best method would be this:
ControlClick("File Upload", "", "Button1")
Edit in response to comments:
Your problem: The fileOpenDialog is blocking execution. You need to think of it as though AutoIt Reads a line, Runs it, then reads the next.
In this case: AutoIt Reads line 1. It creates a FileOpenDialog and WAITS for you to close it. Once it as been closed it reads the next line, and runs that.
Try the following: Create two au3 files, and put the first line in 1.au3 and the second in 2.au3. Run them in that order and see what happens. Send will struggle as the dialog doesn't have focus, but the ControlClick versions should work.
You're not using FileOpenDialog() properly. Its purpose is to interact with the user. If you don't need that, there's no need for it in the first place.
All it does is return the name(s) of the selected files, which you defined already. Can't you just assign the file path to the variable from the start? As per Documentation - Function Reference - FileOpenDialog() :
Success: Returns the full path of the file(s) chosen. Results for
multiple selections are "Directory|file1|file2|..."
This will never work, because AutoIt is not multi-threaded.
Once you open the dialog, it pauses script execution until the user clicks ok, so a Send() function on the next line won't do anything until after.
What you can do is make another script, compile it, and run it just before you open the dialog.
Run("clickOpen.exe")
FileOpenDialog ("File Upload", "C:\Documents and Settings\abhishek.kumar\Desktop\Quadrillion work", "Images (*.jpg;*.bmp)", "","WESTF12433.jpg","" )
This is what would get executed:
WinWaitActive("File Upload")
Send("{ENTER}")
Simple as that! Hope it helps.
