I need to write a small executable which loads IE8 with a specific URL, but also sets the page zoom to default and text size to default (medium).
I can hackishly set the page zoom by sending the ctrl+0 keystroke to the IE window, but there's not really any easy way that I can see to set the text size.
I could go through the menu with keystrokes: alt+z -> x -> m but this is just getting silly. I have no way of knowing whether the menu has shown and whether it's safe to send the next key.
I've looked at the IE command line arguments, but they're really limited.
Any ideas?
Take a look at HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Zoom. You can set a DWORD that corresponds to the zoom level of the page.

I'm able to set the font used to draw the drop-down part of a CMFCToolBarComboBoxButton combo box which is embedded in a CMFCToolBar toolbar. However, I'm not able to set/change the font used for the edit field control which is part of the combo box. I.e., when the combo box is collapsed the currently selected item is always drawn with the standard/default font no matter what font is used for the entries when expanding the box.
I successfully change the font of the drop down box part by using a pointer to the underlying CComboBox object retrieved via CMFCToolBarComboBoxButton::GetComboBox() (and then via CComboBox::SetFont(...)). But when using the method CMFCToolBarComboBoxButton::GetEditCtrl() to obtain a pointer to the edit control part (in order to change its font, too) this method always returns a nulltpr. Does anybody know why or more importantly: What is the correct way to set the font used for the edit control part of the box?
I've searched the web now quite a lot but cannot find a solution to the problem. Thanks for any advice!
Additional note: I need to change the used font(s) at run time in my MFC application.
OK, I finally came to the conclusion that it's better to leave these fonts up to the OS settings anyway and not explicitly set them by the application code.
This is not a technically correct answer to the (my own) question, certainly, but may be a good advide for others chasing the same problem.
I'd like to automate a video-player on a webpage using Selenium in Python.
I cannot locate the interactive parts of the player with driver.find_element_by_... I've decided to try and accomplish this by making browser specific logic that knows how to navigate the page and player via keyboard navigation (count tabs for Chrome, vs Safari, vs Firefox, etc.).
driver.find_element_by_tag_name('body').send_keys(Keys.TAB))
I am able to select each of the controls of the player with tab (play/pause, current position, mute-volume control, full-screen, and additional options) and have had moderate success manipulating the player's controls with ActionChains once selected with TAB navigation
actions = ActionChains(driver)
actions.send_keys(Keys.DOWN) # to reduce volume or
actions.send_keys(Keys.LEFT) # to rewind playback
An example of something that doesn't work as expected with this method is sending a Key.SPACE to the MUTE button when selected. Instead the space is applied as a page navigation action and scrolls down the page like pressing page down. I'm looking for a method that either makes the controls work as expected when manually navigating the page with a keyboard, ex. space on highlighted object interacts and would normally mute the video in this context, or a workaround that lets me accomplish the same thing. To that end I was thinking if I could get the windows coordinates of the TAB selected object within the video-player and simply perform a click that would at least let me interact with the control.
Also if I'm going about this all the wrong way let me know. Thanks!
What you're really looking for is how to navigate the Shadow DOM. Those are the web elements inside the video player.
I answered how to reach inside the Shadow DOM in an other question, albeit for Java. However the principle is the same.
You can read the whole thing at the link, but the basics are you create a "starting point" WebElement at the Shadow DOM via JavaScript, then all future look-ups reference it:
WebElement button = startingPoint.findElement(By.cssSelector("..."));
So im building a basic win32 GUI app and I have a vector of data that gets constantly updated through an external source via a port. Im interested in displaying that list of data to the user but im not sure the best approach to go about it without causing update flickering.
I originally had an edit box in which I build a string with the information and update the window. But it has proved troublesome as the amount of data grows since I cant scroll down to look at additional data. Any ideas?
My idea is no point of updating the visual control as the same speed you receive the data. Because even-though you update at the same speed the users cannot see that change at the speed of data receiving. Human eye does not see a change happening in speed as 1/8th of a second. So better to update the visual control in a controlled manner. Maybe using a timer.
Appending to the text of an edit control for each subsequent data point will lead to flickering as the whole control re-renders as the text has changed.
I'd advise one of the following options:
1) use a ListBox or ListView control; when you add another row item, it only re-draws the new/changed/scrolled item. https://learn.microsoft.com/en-us/windows/desktop/controls/create-a-simple-list-box and https://learn.microsoft.com/en-us/windows/desktop/controls/list-view-controls-overview
2) If you only want an always-scrolling list of data, consider just having a command-line application that writes to the standard output and saves you a lot of trouble - cout or printf your data.
You can also use EM_SETSEL and EM_SCROLLCARET to automatically scroll, but also check the position of the scroll bar before doing that. If not at the bottom, it means that the user wanted to pause, so you can scroll.
Also, you can have the scroll lock key checked in order whether to scroll or not, after all that is what it's name is supposed to do.
We have a rendering listing the selected items in a TreeSelect in the current item. In our case we call them "Tags" (1)
We have added a Field Editor Button to the component to let the editor change selected items. (2) (As described on for example Adding a custom component)
When an editor clicks (2) the editor window (3) it is opened in a dialog. The editor may select different items(called tags in our case) using the TreeSelect.
When the editor presses the ok-button (4) the values are set.
Now to the problem:
The values are actually set as they get stored when the editor presses the Save button but we want our list on the page (1) to immediately reflect the set items when the editor presses the ok-button (4), i.e. before having to actually save the whole item.
How do we achieve that?
(I am in contacts with Sitecore support but so far I have not gotten any answers...)
Update
After a lot of conversation with the support we still have no useful solution.
We tried turning it into a field renderer displaying the links.
What worked was:
The field do get updated when you have edited it in the popup field editor. (but...)
It looks good the first time when page is loaded.
You can make a WebEdit button with commands to edit the field and add it as Custom button to the field (register <command name="webedit:fieldeditor" type="Sitecore.Shell.Applications.WebEdit.Commands.FieldEditor, Sitecore.Client"/> and set Click on the button to webedit:fieldeditor(command={3473DDA1-2983-493C-AF7A-054C75AA7AD3},fields=NameOfField where the guid points to itelf and an "Icon" is set on it.)
What didn't work was:
The field get updated by the raw value, not what I want to display. Server code is involved, but not in the rendering of html-code.
When I want to edit the value in the field editor, the value sent to the field editor is not the raw value but what actually is displayed on the page. (I guess this can be solved somehow)
The issue to the support turned into a feature request to let the server be involved in rendering the field, not just sending a new value to the JavaScript updating it. The server does the first rendering so when it already is involved in updating, it should be allowed to do the rendering the following times too.
We have decided to not spend more time on this right now (we have other things to do too.) and have a bad editor experience as the field not get updated until the editor actually saves the item.
Still we have no suitable solution for this issue. If you want to keep working on it and want a reference to my issue it is 439059.
This may not be useful here. I've done this in normal sites, but not in Sitecore. But, here's one possibility....
This is a situation where you would pass a callback function to the child popup window. This callback will cause the caller / parent window to re-read/re-load the information that was just updated by the child.
Example:
User presses (2) to open Editor Window(3) (Editor window is opened and the Callback function is passed as a parameter)
User presses "OK" button (4). The "OK" button event handler updates the changes, then calls the Callback function which re-loads the now updated information, and closes the popup window.
Once the popup closes, the parent window now displays the information that the popup/editor just updated.
This takes some client side javascript (jquery) development but it is quite do-able normally.
I'm building a VCL c++ builder application. I would like to see if anyone knows of a component that can load data in the lookup upon drop down only after a user has typed a few letters to limit the rows queried? Preferably after pressing Tab, or Enter.
What I would like best is to get a behaviour similar to what Linux command line has, but that might be wishful thinking. The way it would work is to drop down the combo list after user presses tab only if there is multiple options available, and to fill in additional text till the point where characters are not the same anymore, then if user presses tab again, drop down list.
The next best would be if the drop down would only allow drop down if user has typed a few letters, then pressing a specific button opens the dataset with the parameter of the typed text so far, then drops down the combo.
Does a component like this exist?
You can check out TMS Software. I'm not sure if it has something exactly for you, but their components are quite flexible. And you can send a feature request to them - to consider for next update. If you are lucky they might add it to next release.
