I get similar results. How do you interpret the value of $vt = 47663 (0xBA2F)? This seems to be an illegal value.

Since $iPropertyId = 30005 and 30005 means UIA_NamePropertyId which is represented by a BSTR, I would expect a value of vt = VT_BSTR (= 8). Or at least the last 8 bits to have a value of 8. And I would expect the data (the BSTR) to contain the value "Klok", because that's what we get from $oSender.

If we can't interpret $vt properly according to your link in post 358, how should we then be able to read the data of the variant. We need the variant type to read the data.

I still don't think we can use $newValue to get the data. That would have been much easier. I think we need $oSender to get the data.

[junkew]

think we need people like @Trancexx or @Progandy

• No clue how to get directly the data out of the $newValue which just should be a normal variant coming in
• for me the workaround by getting the property myself is fine not sure why getting it directly would be nicer/better/quicker if it could work

not sure if the  0x00000008 neccesarily refers to the VT_BSTR value,
I have seen multiple others flowing by for $newValue so assume its a pointer location

I'll make a test with some C++ code when I get the time for it. Then it's possible to inspect that variant more directly than it is in AutoIt.

[junkew]

c++code only reveals that tagVariant needs an unsigned short instead of word but makes no difference

code below in vc++10 express edition (and windows 7 sdk stuff)

 

reveals a standard variant type. Based on the variant you should be able to get data out of the variant $newValue

 

probably some messing up between 32 and 64 bit windows versions

please post a topic in general help and support and include output from simplespy.

Without any of that information its impossible to help

If possible find a generic reproducer of your problem

And do not forget to turn accessibility on in chrome

Hi,

So there is not any simple function to send an e-mail automatically. I hope a simple function like this will exists in AutoIt built-in functions. 

SendAnEmail("ID","Subject", "Attachment1_file_path", "Attachment2_file_path",....)

This function will automatically opens chrome, and login to my gmail id. If i already logged in, then press the compose button and fill the ID area and subject and attach all the attachments and send the email. Can i get a simple function like this one? 

[junkew]

yes, you can if you start coding with the simple functions in the iuiautomation library.

but for sure doing it thru UI interfaces is most likely not efficient and/or fast

suggestion is to post in general help and support of even in gmail forums

Hi junkew,

Thanks. let me read that links.

[krupa]

Hi. I have a problem with run examples.

 

UIAWrappers.au3"(978,81) : warning: $STR_REGEXPMATCH: possibly used before declaration.

$iMatch = StringRegExp($propertyActualValue, $propertyVal, $STR_REGEXPMATCH)

 

I wrote some scripts but every time I run it I get new logfile - How can I disable it?

Also I have some problem with grids (DataGridCell). I can read row, column etc - But how I can read value in that grid?

Thanks for helping me

[junkew]

Please post in general help and support and attach information as is requested in first post of this thread. Most likely you use incompatible autoit version.

[trekker]

I have installed the framework and simplespy seems to be working fine.

I adjusted all the variables, but not sure on this one:

const $cToolbarByName = "name:=Google Chrome Toolbar"  

What is the Toolbar element?

 

Running the code opens Chrome, but then i get this message:

"C:Documents and SettingsAdministratorDesktopchrome.au3" (35) : ==> Variable used without being declared.:

$oChrome=_UIA_getFirstObjectOfElement($oDesktop,"class:=Chrome_WidgetWin_1", $treescope_children)

 

 

Indeed i don't see oChrome declared anywhere? Should it be done by the includes or am i missing something?

 

EDIT must have a type as the downloaded example is working; will check tonight when more time

A month ago, we had a discussion of a matter in post 337: How do we get information directly from the $newValue variant parameter in the callback function for the property changed event handler? The relevant posts are 349 and 357 - 364.

I have made a test with the following C++ code:

expandcollapse popup

// Defines an event handler for property-changed events, and listens for
// ToggleState property changes on the element specifies by the user.
#include <windows.h>

}

Because the issue in post 337 is about name property changes, I'm using UIA_NamePropertyId instead of UIA_ToggleToggleStatePropertyId.

To test the code you need some name property changes. A control where the name changes regularly, so you can see some events. You can find such controls in Windows Task Manager. In the status bar in the bottom of the window you find three labels that shows some numbers. These numbers are added directly to the label name. When the numbers are updated and added to the label name, it generates name property change events.

This is the output for the CPU Usage:

expandcollapse popup

-Use the mouse to point to the element you want to listen from.
-Adding Event Handler.
-Press any key to remove event handler and exit
>> Property 30005 changed. newValue.vt = 8. newValue.bstrVal = CPU Usage: 1%.

The output is as expected: 30005 is the name property, the variant type vt = 8 is a BSTR, and the variant value bstrVal = "CPU Usage: 1%" matches the name property from the sender object (pSender).

The $newValue variant parameter with a value of 0x00000008 is expected to be a pointer. But this is not a pointer. This is the first element of the variant structure, which is the variant type. Here we have a variant type with a value of 8, which means that the data in the variant is a BSTR.

We expect a pointer, but we are not getting a pointer. There is definitely something wrong with the AutoIt code.

Why do we expect a pointer? Because a variant is replaced by a pointer in the ObjectFromTag function by trancexx (in the regular expression).

Why have trancexx replaced a variant with a pointer? Because the callback function is implemented with DllCallbackRegister. This function takes only simple variables as parameters. A variant can't be used as parameter.

A variant is defined as a structure:

Global Const $tagVARIANT = "word vt;word r1;word r2;word r3;ptr data; ptr;"

This is a 16 byte/128 bit structure on a 32 bit system, and a 24 byte/192 bit structure on a 64 bit system. But DllCallbackRegister can't take a structure as parameter. It can take a pointer as parameter. That's the reason why trancexx have replaced the variant with a pointer.

And now we are approaching the real problem. The HandlePropertyChangedEvent method of the IUIAutomationPropertyChangedEventHandler interface object does not take a pointer to a variant as parameter. It takes a variant structure as parameter.

HandlePropertyChangedEvent is implemented with DllCallbackRegister. HandlePropertyChangedEvent needs a variant structure as parameter. DllCallbackRegister can't handle a variant structure.

There seems not to be an easy solution for this problem.

[junkew]

Although not working as expected whats wrong by retrieving the property within the event instead of using newvalue parameter. In other words what am i missing as usefull information now newvalue has not the information directly but just retrieving the actual value gives me same resukt.

[LarsJ]

Nothing wrong with this at all. But it would be easier and faster to get the new value directly from the $newValue parameter without the need to create the $oSender object.

[mLipok]

I see there is partialy support for AFX controls.

I just trying to get text from "Afx:StatusBar:400000:8:10003:10"

And I have only negative results.

But maybe I'am doing something wrong ?

[LarsJ]

Is the Spy tool able to identify and mark the control with a red box? If this is the case then please post the output.

If not then try to identify the control with Inspect.exe from Windows SDK.

[mLipok]

I PM you this because "some way" , for me, it is restricted content.

EDIT: There is Company name and Phone number, and maybe some other data.

Hi, I am interested in your udf. However, I cannot use it well. I want to automate firefox and the autoit report the following information:

>"C:Program Files (x86)AutoIt3SciTE..autoit3.exe" /ErrorStdOut "E:autoittestff.au3"    

"E:autoittestff.au3" (48) : ==> Variable used without being declared.:

$oFF=_UIA_getFirstObjectOfElement($oDesktop,"class:=MozillaWindowClass", $treescope_children)

$oFF=_UIA_getFirstObjectOfElement(^ ERROR

>Exit code: 1    Time: 14.41

My system is Win7 x64 firefox is Ver 36.0.4. 

How can I resolve this problem?
