I am trying to make WatiN attach to an IE popup window (IE 10).
This popup contains a frameset --> a single frame --> a pdf document.
My goal is to save this pdf to my disk.
Dim winExists = IE.Exists(Of IE)(Find.ByUrl(Function(url) url.Contains("__ADFvDlg")))
If winExists Then 'this evaluates to true
Dim win = IE.AttachTo(Of IE)(Find.ByUrl(Function(url) url.Contains("__ADFvDlg"))) ' Timeout while waiting for frame document becoming available
End If
1) I have tried using the above code inline or in a STA thread
2) When coded inline, its parent thread is also STA
3) I have tried to increase the default timeout to 8 minutes, same result after 8 minutes have passed
There is no other option for me than to parse this particular popup, since it is a site built with Oracle ADF and, apart from the fact that it is A MESS, it is very strange at times...this popup has a URL that somehow works only once. If I try to use it in another window, no pdf is returned. The same happens when I refresh the popup.
I cannot fetch the PDF in the Temporary Internet Files since it is not there (I suppose this is because the website works under SSL).
Any guidelines or solutions even outside WatiN's scope is more than welcome since I've hit a brick wall.
Technologies: VS2012, WPF
Thanks a lot in advance.
I found it easiest when I tried the same thing by making the pop-up show up as a new tab. That way I could attach to it's URL. From there I would use
File.WriteAllText(fileName, responseDownLoad.Content.ReadAsStringAsync().Result);
Where responseDownload will be a HttpResponseMessage

I am attempting web automation with a platform called Robocorp using the Selenium library.
When I run my program, I have no issues until I encounter this page where I am trying to get the program to click on the icon that says SQL.
I want the <a> element with the #href attribute.
Here are some (of many) XPaths I have tried that have all failed:
xpath://a[contains(#href,'sql_form.jsp')]
xpath://*[text()='SQL']
xpath://a[#target='frame2]
Snapshot of the element:
I circled the element in red ^^^
I cannot get the selector to be recognized on this page. I have tried adding delays, waiting until the element is active, waiting until the element is visible, etc.
Nothing seems to work.
Here is an image of the elements I am trying to select.
(The link in the href element takes me to the page I am trying to access).
I thought that the third one would for sure work but is still failing.
I am using a platform called Robocorp which only needs the raw selector to work (CSS or XPath)
I was unaware that iframe needed to be handled differently or that it even existed
https://robocorp.com/docs/development-guide/browser/how-to-work-with-iframes
I first needed to switch frames.
To identify the element with text as SQL you can use you can use either of the following locator strategies:
Using Wait Until Element Is Visible:
Wait Until Element Is Visible xpath=//a[starts-with(#href, 'sql_form.jsp') and #target='frame2']/font[text()='SQL'] 10 seconds
Using Wait Until Element Is Enabled:
Wait Until Element Is Enabled xpath=//a[starts-with(#href, 'sql_form.jsp') and #target='frame2']/font[text()='SQL'] 10 seconds

I am kind of new to Silverlight and I am having some issues. I have been trying to figure this out for a few hours now...
I have a main page that waits for a packet from a server. When that packet arrives it is handled in a module. Depending on the packet data the module handles an action. Some of those actions involve subroutines on the main page. I access them via:
Dim MainPage As MainPage = App.Current.RootVisual
If strPacketData(1) = "0" Then
MainPage.Do_Sign_In(True, strPacketData(2))
Else
MainPage.Do_Sign_In(False, strPacketData(2))
End If
And this works fine.
Assuming the sign in works the main page calls
Me.Content = New Page2
And the page switches to Page2
The problem is that the same code doesn't work when trying to access subs and controls on page2.
If I try:
Dim Page2 As Page2 = App.Current.RootVisual
If strPacketData(1) = "1" Then
Page2.lblCreateError.Opacity = 100
End If
I get Unable to cast object of type 'SLClient.MainPage' to type 'SLClient.Page2'.
What I am getting from this is that App.Current.RootVisual is set to MainPage, but MainPage shouldn't be open...
I have tried setting App.Current.RootVisual to Page2 but that doesn't seem to do anything.
I am hoping that this issue is caused by my ignorance of silverlight and that there is an easy fix for this...
I guess what I need to do is detect which page is currently being displayed and manipulate the controls and functions\subroutines on that page.
Any Input would be greatly appreciated.
OK well I finally figured it out. Or at least I figured out a way to do it.
I used a dictionary to store the addresses of the pages once they were created in memory. I also modified the program so that rootVisual is its own grid instead of a page. Now the grid loads and clears the pages as children.
I don't know... Silverlight is kind of screwy. Whatever, it works now.
I am using GPUImage framework to record multiple videos one after other in close intervals with having various filters enabled in real time using GPUImageVideoCamera and GPUImageMovieWriter.
When I record the video, video starts with a jerk(freeze for half a seconds) and ends with a jerk also. I know the reason behind this are the statements in which I pass the movieWriter object to VideoCamera's audioEncodingtarget.
So In my case when I record multiple videos one after other(with different objects of GPUImageMovieWriter), the video preview view freezes at start and end of each recording.
If I remove the audio encoding target statement, conditions improves significantly but of course I don't get the audio.
Currently I am using a AVAudioRecorder while recording to save audio tracks but I believe this is not a ideal work around.
Is there any way to solve this problem.
-- I looked at the RosyWriter example by Apple, their app work almost similarly but smoothly at almost constant 30 fps. I tried to use the RosyWriter code(after removing the code that add purple effect) to save the required videos while showing GPUImageVideoCamera's filtered view to user but in vain. When applied unmodified rosywriter code just records two videos and rest video fails. I also tried to pass in the rosywriter code the capture session from GPUImageVideoCamera but only gets videos with black frames and no audio.
Please help on how can I can record GPUImage filtered videos with audio without this jerkiness. Thanks in advance
I faced the same issue and here is my workaround.
As you pointed out, this problem happened because setAudioEncodingTarget method internally calls addAudioInputsAndOutputs to set audio in/output to the capture session.
To avoid this issue, I created justSetAudioEncodingTarget method for VideoCamera as below,
(on GPUImageVideoCamera.m)
// just set
-(void)justSetAudioEncodingTarget:(GPUImageMovieWriter*)newValue {
if( newValue == nil ) {
return;
}
addedAudioInputsDueToEncodingTarget = YES;
[super setAudioEncodingTarget:newValue];
}
The following steps is my scenario and I checked out it smoothly worked.
Called VideoCamera's addAudioInputsAndOutputs after the VideoCamera was created.
This is not right before starting the recording. :)
Set MovieWriter to the VideoCamera by justSetAudioEncodingTarget that I made above.
I have a WPF WebBrowser Control in a WPF app, on a web page (visited in the WPF browser) I have a VBScript Print() sub to print a receipt without promoting the user.
<script language='VBScript'>
Sub Print()
OLECMDID_PRINT = 6
OLECMDEXECOPT_DONTPROMPTUSER = 2
OLECMDEXECOPT_PROMPTUSER = 1
call WB.ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER,1)
End Sub
document.write "<object ID='WB' WIDTH=0 HEIGHT=0 CLASSID='CLSID:8856F961-340A-11D0-A96B-00C04FD705A2'></object>"
</script>
Since adding this VBScript Print() I now am prompted with the following in my WPF Browser:
internet explorer blocked an activex control so this page might not
display correctly
How can I either prevent the message and just run the script, or at very worst show a prompt?
The solution for us in the end was to use Silverlight 5 to print the page without prompting the user as Silverlight 5 provides a way to print without prompting the user using ElevatedPermissions.
I am trying to figure out how to make a hyperlink in a Livecycle Form which points to a URL which will change on different days that the form is rendered. For example on one day I might want the hyperlink to point to:
mywebsite/mypage?option=XXX
and on another day I want it to point to:
mywebsite/mypage?option=YYY
The XXX and YYY can be passed into the form's data pretty easily as XML, but I just don't know how to make it so that the hyperlink is changed to correspond to this.
Any suggestions?
This can be accomplished with JavaScript in LiveCycle Designer. The following script, placed on the Form's docReady event will let you dynamically change the URL of a text object.
form1::docReady - (JavaScript, client)
// If this code is running on the server, you don't want it to run any code
// that might force a relayout, or you could get stuck in an infinite loop
if (xfa.host.name != "XFAPresentationAgent") {
// You would load the URL that you want into this variable, based on
// whatever XML data is being passed into your form
var sURL = "www.stackoverflow.com"; // mywebsite/mypage?option=xxx
// URLs are encoded in XHTML. In order to change the URL, you need
// to create the right XHTML string and push it into the Text object's
// <value> node. This is a super simple XHTML shell for this purpose.
// You could add all sorts of markup to make your hyperlink look pretty
var sRichText = "<body><p>Foo</p></body>";
// Assuming you have a text object called "Text1" on the form, this
// call will push the rich text into the node. Note that this call
// will force a re-layout of the form
this.resolveNode("Text1").value.exData.loadXML(sRichText, false, true);
}
There are a couple of caveats: URLs in Acrobat are only supported in Acrobat 9.0 and later. So if someone using an older version of Acrobat opens your form, the URLs won't work.
Also, as you can see from the "if (xfa.host.name !=...)" line, this code won't run properly if the form is being generated on the server, because forcing a re-layout of a form during docReady can cause problems on certain older versions of the LiveCycle server. If you do need to run this script on the server, you should probably pick a different event then form::docReady.
I a number of complaints from users in WorkSpace that clicking links opened them in the same tab so they lost their WorkSpace form, and there's no option to change that in Designer 11. I think the solution I came up with for that would work for you too.
I made buttons with no border and no background, and in their click event have this line (in Javascript, run at client)
app.launchURL("http:/stackoverflow.com/", true);
It would be easy to add some logic to choose the right URL based on the day and it doesn't cause any form re-rendering.
In some spots where the hyperlink is in line with other text, I leave the text of the link blue and underlined but with no hyperlink, and just place the button (no background, no border, no caption) over it. Does require positioned and not flowed subforms for that to work, so depending on your layout it could get a little clunky.
Wow, just realized I am super late to the party. Well, for anyone using ES4 facing a similar problem . . .
Ended up using a 3rd party component to manipulate the PDF's hyperlinks...wish there was a better solution as this one costs about $1000.
