i have been looking for a while now, i have found a solution in csharp , but i couldn't translate it (implement it in my vb.net app).
My only aim is that when the user clicks a link no popups appear.
thank you for your help.
My vb.net coding skill is beginner level, c sharp no knowledge.
the working solution in c sharp:
using CefSharp;
using CefSharp.WinForms;
namespace popup_cefsharp
{
public partial class frm_main : Form
{
public frm_main()
{
InitializeComponent();
}
//variable
ChromiumWebBrowser chrome, chrome_popup;
private void initialize_browser()
{
try
{
CefSettings settings = new CefSettings();
Cef.Initialize(settings);
//main browser
chrome = new ChromiumWebBrowser(this.txt_url.Text.Trim());
LifespanHandler life = new LifespanHandler();
chrome.LifeSpanHandler = life;
life.popup_request += life_popup_request;
this.pan_container.Controls.Add(chrome);
chrome.Dock = DockStyle.Fill;
//second browser (popup browser)
chrome_popup = new ChromiumWebBrowser("");
this.pan_container_popup.Controls.Add(chrome_popup);
chrome_popup.Dock = DockStyle.Fill;
}
catch (Exception ex)
{
MessageBox.Show("Error in initializing the browser. Error: " + ex.Message);
}
}
private void carregar_popup_new_browser(string url)
{
//open pop up in second browser
chrome_popup.Load(url);
}
private void frm_main_FormClosing(object sender, FormClosingEventArgs e)
{
//close o object cef
Cef.Shutdown();
Application.Exit();
}
private void frm_main_Load(object sender, EventArgs e)
{
//initialize the browser
this.initialize_browser();
}
private void life_popup_request(string obj)
{
//function for open pop up in a new browser
this.carregar_popup_new_browser(obj);
}
}
}
link original post: https://www.codeproject.com/Articles/1194609/Capturing-a-pop-up-window-using-LifeSpanHandler-an
finally found the solution , if anyone is interested
here is the link, you will need to install the cefsharp nuggets packages, add lifespanhandler as a new class, the file is in the link, then copy the method to call the function from the mainform...
cheers...

My goal is to programmatically create .doc on Google Drive with text and generated shapes.
My first problem that I cannot overcome is that when I create a doc file the file is generated saved on google drive but can not be opened .
Before when I created plain text files everything was OK.
private void createFile() {
final Task<DriveFolder> rootFolderTask = getDriveResourceClient().getRootFolder();
final Task<DriveContents> createContentsTask = getDriveResourceClient().createContents();
Tasks.whenAll(rootFolderTask, createContentsTask)
.continueWithTask(new Continuation<Void, Task<DriveFile>>() {
#Override
public Task<DriveFile> then(#NonNull Task<Void> task) throws Exception {
DriveFolder parent = rootFolderTask.getResult();
final Task<MetadataBuffer> Createlist = getDriveResourceClient().listChildren(parent);
DriveContents contents = createContentsTask.getResult();
OutputStream outputStream = contents.getOutputStream();
try (Writer writer = new OutputStreamWriter(outputStream)) {
writer.write("Witaj z nuclearhelperaa");
}
MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
.setTitle("test6")
// .setMimeType("text/plain")
.setMimeType("application/msword")
.setStarred(true)
.build();
return getDriveResourceClient().createFile(parent, changeSet, contents);
}
})
.addOnSuccessListener(this,
new OnSuccessListener<DriveFile>() {
#Override
public void onSuccess(DriveFile driveFile) {
showMessage(getString(R.string.file_created,
driveFile.getDriveId().encodeToString()));
finish();
}
})
.addOnFailureListener(this, new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.e(TAG, "Unable to create file", e);
showMessage(getString(R.string.file_create_error));
finish();
}
});
// [END create_file]
}
Is my task possible? I mean after creating a doc put some images formatted text and generated shapes (I need to create very simple picture containing couple dots) is possible to fulfil and if yes do you know some good libraries to make it possible?
I'm having an issue with duplicated content from redirected output.
In my forms I have two buttons: Run and Clear.
public partial class BatchRun : Form
{
Process process = new Process();
public BatchRun()
{
InitializeComponent();
}
private void RunBTN_Click(object sender, EventArgs e)
{
//initiate the process
this.process.StartInfo.FileName = sMasterBATname;
this.process.StartInfo.UseShellExecute = false;
this.process.StartInfo.CreateNoWindow = true;
this.process.StartInfo.RedirectStandardOutput = true;
this.process.OutputDataReceived += new DataReceivedEventHandler(StandardOutputHandler);
this.process.StartInfo.RedirectStandardInput = true;
this.process.Start();
this.process.BeginOutputReadLine();
}
public void StandardOutputHandler(object sender, DataReceivedEventArgs outLine)
{
BeginInvoke(new MethodInvoker(() =>
{
Label TestLBL = new Label();
TestLBL.Text = text.TrimStart();
TestLBL.AutoSize = true;
TestLBL.Location = new Point(10, CMDpanel.AutoScrollPosition.Y + CMDpanel.Controls.Count * 20);
CMDpanel.Controls.Add(TestLBL);
CMDpanel.AutoScrollPosition = new Point(10, CMDpanel.Controls.Count * 20);
}));
}
private void ClearBTN_Click(object sender, EventArgs e)
{
CMDpanel.Controls.Clear();
this.process.CancelOutputRead();
this.process.Close();
this.process.Refresh();
}
}
This works great if I want to run process only once i.e. close the forms once process has completed.
However, I need to allow user to rerun the same process or run a new one hence I have added a clear button the clear various controls etc.
The problem I'm having is that after clicking clear button, I want to click run button again without closing which should then run the sMAsterBAT file(CMD).
StandardOutputHandler seems to be including content of the previous run as well as the new one resulting in duplicated labels in my CMDpanel.
Is this stored in some kind of buffer? If so, How do i clear it to allow me a rerun?
Could someone explain why this is happening and how to resolve it please.
Spoke to someone at work who fixed it for me. So easy lol
private void ClearBTN_Click(object sender, EventArgs e)
{
CMDpanel.Controls.Clear();
this.process.CancelOutputRead();
this.process.Close();
this.process.Refresh();
this.process = new Process(); // this line resolved my issue!!
}
}
I have developed a s keyword driven framework. It has a action keyword to switch the frame.
It works fine with Mozilla. But when it comes to IE it is not switching. It logs error.
IE driver -IEDriverServer_x64_2.44.0
IE version -9
Selenium version -selenium-java-2.44.0
Thanks in advance.
public static void switchFrame(String object,String data)throws Exception{
try{
driver.switchTo().frame("Ifrm");
Log.info("Switched the frame");
}
catch(Exception e){
Log.error("Not able to switch the frame--- " + e.getMessage());
DriverScript.bResult = false;
}
}
Here exception occurs.
I assume, the value you specified in frame is id/name/etc. You have to access the frame by calling the driver with specified value. Code would be
driver.switchTo().frame(driver.findElement(By.id("Ifrm")));
Selenium won't let me switch to the iframe by ID on Internet Explorer, but it does allow me to switch by index. If you have some sort of property that you can check that it is only available on the iframe you can do the following
new WebDriverWait(driver, 5).until(
new Predicate<WebDriver>() {
#Override
public boolean apply(WebDriver input) {
try {
int i = 1;
while (true) {
driver.switchTo().defaultContent();
driver.switchTo().frame(i);
String aClass =
driver.findElement(By.xpath("/html/body"))
.getAttribute("class");
if (aClass.contains("modal")) {
return true;
}
++i;
}
} catch (NoSuchFrameException e) {
return false;
}
}
}
);
In my case I was looking for a body class of modal
I am new to UCMA and I am learning as I go through examples. I am trying to build 2 Lync clients A and B with the scenario as follows,
A calls B
B answers
A plays audio
B records it using Recorder.
I am stuck at trying to record the call at B. For B its an incoming call. I need to attach the audiovideoflow to the recorder, but I am not sure on how to do it. I will appreciate any help.
Apologies on the unformatted code, I am not sure how to format it properly, I tried.
Thanks.

I think I have figured out what's not quite right here.
Your Code
// Create a user endpoint, using the network credential object
// defined above.
_userEndpoint = _helper.CreateEstablishedUserEndpoint("Lync UAS" /*endpointFriendlyName*/);
_userEndpoint.RegisterForIncomingCall<AudioVideoCall>(On_AudioVideoCall_Received);
Console.WriteLine("Waiting for incoming call...");
_autoResetEvent.WaitOne();
Console.WriteLine("came after call is connected");
//start recording for audio.
Recorder recorder = new Recorder();
recorder.StateChanged += new EventHandler<RecorderStateChangedEventArgs>(recorder_StateChanged);
recorder.VoiceActivityChanged += new EventHandler<VoiceActivityChangedEventArgs>(recorder_VoiceActivityChanged);
//**********This is the issue, currently _audioVideoFlow is null, it is not attached to the flow //So this will fail, how to attach _audioVideoFlow to an incoming call ?? HELP !!!
// recorder.AttachFlow(_audioVideoFlow); ------------> HELP!
Looking good so far. I'm assuming you're establishing and such in your CreateEstablishedUserEndpoint method, but I'm not seeing where you're getting the value for _audioVideoFlow.
I'm guessing you might be doing it elsewhere, but on the off chance that's actually where you're running into problems, here's that bit:
Simplest pattern to get AVFlow
public static void RegisterForIncomingCall(LocalEndpoint localEndpoint)
{
localEndpoint.RegisterForIncomingCall
<AudioVideoCall>(IncomingCallDelegate);
}
private static void IncomingCallDelegate(object sender, CallReceivedEventArgs<AudioVideoCall> e)
{
e.Call.AudioVideoFlowConfigurationRequested += IncomingCallOnAudioVideoFlowConfigurationRequested;
}
private static void IncomingCallOnAudioVideoFlowConfigurationRequested(object sender, AudioVideoFlowConfigurationRequestedEventArgs e)
{
AudioVideoFlow audioVideoFlow = e.Flow; // <--- There's your flow, gentleman.
}
Now, instead of registering for your incoming call, just call RegisterForIncomingCall(_userEndpoint);.
Your AVFlow will be hanging off e.Flow above, you could then pass that into your recorder: recorder.AttachFlow(e.Flow) or simply assign the flow to a field in your class and autoResetEvent.WaitOne(); and set that up where you're setting that up now.
Obviously this is a pretty naive implementation. A lot can go wrong in those few lines of code (exception handling/static event handler memory leak comes immediately to mind); don't forget to wire up events related to status changes on the conversation/call and endpoints, as well as any of the recovery related items.
I have following two methods. When user clicks on start button from ui, the step geoLocator_PositionChanged in geoLocator_PositionChanged method is fired and calls the other method geoLocator_PositionChanged.But when it comes to try block while executing the first statement it throws the following error:
"The application called an interface that was marshalled for a different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD))"
private async void btnStartStop_Click_1(object sender, RoutedEventArgs e)
{
geoLocator.PositionChanged += geoLocator_PositionChanged;
}
async void geoLocator_PositionChanged(Geolocator sender, PositionChangedEventArgs args)
{
MessageDialog msgdlg = null;
bool bDisplayDialog = false;
try
{
lblAltValue.Text = args.Position.Coordinate.Altitude.ToString();
}
catch
{
}
}
Any help how can I fix this issue ?
You try to access the UI-Thread from another one.
Try something like ths
Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync
(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
{
//HERE GOES THE UI ACCESS LIKE this.textbox.text = "MY AWESOME TEXT";
});
