help you fix your problem Well, I found the answer days ago.
There are two windows of Google Chrome with the same class name "Chrome_WidgetWin_1" and I was trying to active the first one, when the useful windows is the second one. So, I searched for the second window and later used SetForegroundWindow() with that window.
code :
//Getting the HWND of Chrome
HWND chromeWindow = FindWindow("Chrome_WidgetWin_1", NULL);
HWND chrome = GetWindow(chromeWindow, GW_HWNDNEXT);

//Setting the window to the foreground (implies focus and activating)

Does that help I have some JavaScript that is being used to open a new window and display a PDF file. This is working fine apart from the title of the new window being open. I am using the window.open function and I have set the title of the page using the document.write function (see code below). The code works fine for FF and IE but for some reason Google Chrome just displays 'Untitled - Google Chrome' , Works for me when I set the 1st parameter of open() to 'about:blank'

Does that help I want to set different browserAction icons in different windows. The only method I found for this is: , Here is my solution, I hope it will be helpful:
code :
function setIcon(state, getIconNameCallback) {

    // we need to set the icon globally first, 
    // to avoid blinking to default icon

    chrome.windows.getLastFocused(null, function(window) {
        chrome.tabs.getSelected(null, function(tab) {
                'path': getIconNameCallback(state, tab.url)

    // then we must set the icon for each tab,
    // without that the extension wont behave
    // properly with multiple windows

    chrome.tabs.query({}, function(tabs) {
        for (var i = 0; i < tabs.length; i++) {
                'path': getIconNameCallback(state, tabs[i].url), 
                'tabId': tabs[i].id

This might help you UPDATE- chrome.tabs.update(tabId, {selected: true}); achieves what I needed. Here's the final code:
code :
chrome.browserAction.onClicked.addListener(function(tab) {
    var found = false;
    var tabId;
    chrome.tabs.query({}, function (tabs) {
        for (var i = 0; i < tabs.length; i++) {
            if (tabs[i].url.search("www.pandora.com/") > -1){
                found = true;
                tabId = tabs[i].id;
        if (found == false){
            chrome.tabs.executeScript(null,{file: "buy.js"});
        } else {
            chrome.tabs.update(tabId, {selected: true});

Setting focus when control's top level parent window is the active window?

Setting focus when control's top level parent window is the active window?

should help you out There are two levels of "focus". One is "focus" of Control inside form. And one is "focus" of Form inside whole composition of windows on desktop.
The Control use these members:
code :
public class MyControl : FlowLayoutPanel {
    private TextBox textBox1;
    private TextBox textBox2;

    public MyControl() {
        this.textBox1 = new TextBox();

        this.textBox2 = new TextBox();

        this.BackColor = Color.Blue; // not required

        this.MouseEnter += this.MyControl_MouseEnter;

    private void MyControl_MouseEnter(object sender, EventArgs e) {
        this.textBox1?.Focus(); // sets focus to the control

        var parentForm = this.FindForm();
        parentForm?.Activate(); // activates the form
