I'm developing a Add-in for PowerPoint that inserts images in the document.
I'm currently able to insert the image, but what I'm not able to do is to replace a current selected image.
So, for example, imagine that:
The user added an image available on the Add-in, inside an empty slide
He then selected this image and wants to replace it with another one also available on the Add-in.
He clicks/selects the slide image, and then clicks on the image inside the Add-in that he wants to replace.
The thing is that I'm not able to get his selection with the Office API.
Can someone help me?
My current code looks like this:
const insertFile = (binaryStr: string) => {
Office.context.document.setSelectedDataAsync(
binaryStr,
{
coercionType: Office.CoercionType.Image,
},
(result) => {
if (result.status === Office.AsyncResultStatus.Failed) {
console.error(result.error.message);
}
}
);
};
Try to use the getSelectedDataAsync method which reads the data contained in the current selection in the document.

I am developing an add-in for PowerPoint which receives data from a server with WebSockets. When data is received, I update the slide.
But, I want to know if it's possible to update slide content (Text, XmlSvg...) after the presentation is started? And how?
Currently, I update content like this but when I try during presentation, I got an internal error:
Office.context.document.setSelectedDataAsync(
myText,
{
coercionType: Office.CoercionType.Text
},
result => {
if (result.status === Office.AsyncResultStatus.Failed) {
console.error(result.error.message);
}
}
);
Thanks for your help.
After going over ANY option possible, I can't find a solution to a simple problem :
Letting a user select a photo from a large gallery and save it to collection.
Like an image picker, you pick an image from a gallery and the window is closed.
No photo selection option on "user input" menu.
No way to connect any gallery including Wix Gallery to a data set as INPUT.
3rd apps let you do that but it's being saved in their own servers, and its limited to just a few photos, not to a large set
We basically have more than 100 photos in an album that a user should be able to somehow pick.
Another option is to open some kind of window with Pinterest stream and collect the URL of a selection, which also seems impossible.
There is no built-in image picker, but you can roll your own with a bit of code.
Here's a bit of code that should get you started in the right direction:
import wixData from 'wix-data';
import wixUsers from 'wix-users';
$w.onReady(function () {
$w('#gallery').clickAction = "none";
$w("#gallery").onItemClicked( (event) => {
let imageSrc = event.item.src;
let toInsert = {
"user": wixUsers.currentUser.id,
"image": imageSrc
}
wixData.insert("SelectedImages", toInsert)
.then( () => {
$w('#gallery').hide("fold");
} );
} );
} );
This code assumes you have a collection where you want to store "selected" images. That collection has at least two fields that have the following keys: user and image.
When an image in the gallery is clicked an event handler gets the src of the image and inserts it into the collection along with the current user's ID. Then the gallery is hidden.
All of the above can be customized to fit your specific situation, but this should give you an idea of what can be done.
I have a screen where we have 4 tabs, each tab should be displayed as per the login priority.
Ex:Department,Role,Employee,Screen are the tabs.
Each tab is having buttons to add,edit,remove the data.
by default when i log with any user its going to the first tab, but not all the users are having the first tab as their requirement.
how can i resolve this to do it dynamically in html client application
As covered towards the end of the following LightSwitch Team blog post, you can programmatically change the tab by using the screen.showTab method:
Creating a wizard-like experience for HTML client (Andy Kung)
However, in order to use this showTab API command when your screen is loading, its use needs to be delayed until the screen has fully displayed. This can be achieved in your screen's created method by using a combination of the jQuery mobile pagechange event (as the LightSwitch HTML Client uses jQuery mobile) and a setTimeout with a zero timeout (to delay the showTab until the loading screen is rendered).
The following shows a brief example of how you can use this approach to dynamically set the initial screen tab:
myapp.BrowseScreen.created = function (screen) {
var initialTabName = localStorage.getItem("Rolename") + "Tab";
$(window).one("pagechange", function (e, data) {
setTimeout(function () {
screen.showTab(initialTabName);
});
});
};
Based on your earlier post it appears that you're using LocalStorage to track your logged in user and their role.
On this basis, the above example assumes that the user's role will be the factor dictating the tab they are shown when the screen loads (the screen is named BrowseScreen in the above example).
It also assumes that your tabs are named after each employee role (suffixed with the text 'Tab') e.g. a user who is assigned the role 'DepartmentManager' would be directed to a tab called 'DepartmentManagerTab'.
Whilst slightly more involved, if you'd prefer to avoid the pagechange and setTimeout it's possible to customise the LightSwitch library to introduce a new navigationComplete screen event. This new event is ideal for executing any operations dependent upon the screen having fully rendered (such as navigating to a different tab using the showTab function).
If you'd like to introduce this additional event, you'll need to reference the un-minified version of the LightSwitch library by making the following change in your HTML client's default.htm file (to remove the .min from the end of the library script reference):
<!--<script type="text/javascript" src="Scripts/msls-?.?.?.min.js"></script>-->
<script type="text/javascript" src="Scripts/msls-?.?.?.js"></script>
The question marks in the line above will relate to the version of LightSwitch you're using.
You'll then need to locate the section of code in your Scripts/msls-?.?.?.js file that declares the completeNavigation function and change it as follows:
function completeNavigation(targetUnit) {
msls_notify(msls_shell_NavigationComplete, { navigationUnit: targetUnit });
var screen = targetUnit.screen;
var intialNavigation = !screen.activeTab;
var selectedTab = targetUnit.__pageName;
if (screen.activeTab !== selectedTab) {
callNavigationUnitScreenFunction(targetUnit, "navigationComplete", [intialNavigation, selectedTab]);
screen.activeTab = selectedTab; // Set at the end of the process to allow the previous selection to be referenced (activeTab)
}
}
function callNavigationUnitScreenFunction(navigationUnit, functionName, additionalParameters) {
var screenObject = navigationUnit.screen;
var constructorName = "constructor";
var _ScreenType = screenObject[constructorName];
if (!!_ScreenType) {
var fn = _ScreenType[functionName];
if (!!fn) {
return fn.apply(null, [screenObject, navigationUnit].concat(additionalParameters));
}
}
}
You can then use this new event in your screens as follows:
myapp.BrowseScreen.navigationComplete = function (screen, navigationUnit, intialNavigation, selectedTab) {
if (intialNavigation) {
var initialTabName = localStorage.getItem("Rolename") + "Tab";
screen.showTab(initialTabName);
}
};
This event fires whenever a navigation event completes (including a change of tab) with the initialNavigation parameter being set to true upon the initial load of the screen and the selectedTab parameter reflecting the selected tab.
Although modification to the LightSwitch library aren't uncommon with some of the more seasoned LightSwitch developers, if you decide to go down this path you'll need to thoroughly test the change for any adverse side effects. Also, if you upgrade your version of LightSwitch, you'll need to repeat the library modification in the new version.
Morning,
We have literally searched all over Stackoverflow and Google to find this solutions but still don't have the right answer.
We're trying to auto-set the Base, Small and Thumbnail options on the first uploaded image, so when uploading multiple images the first image will always have all three options checked.
If anyone has tried and succeeded with find this answer and advice, Thank you.
It is very easy. Example's here. Replace in root/js/mage/adminhtml/product.js in the end of handleUploadComplete around 120 row code
this.container.setHasChanges();
this.updateImages();
},
updateImages : function() {
with
this.container.setHasChanges();
this.updateImages();
$$('tr#media_gallery_content-image-1 td.cell-image.a-center input')[0].setAttribute('checked','checked');
$$('tr#media_gallery_content-image-1 td.cell-small_image.a-center input')[0].setAttribute('checked','checked');
$$('tr#media_gallery_content-image-1 td.cell-thumbnail.a-center input')[0].setAttribute('checked','checked');
},
updateImages : function() {
And enjoy autoselect first image after upload
If you have already uploaded your images and need to set the first one as thumb/base/small try the sql command in this post:
Just follow the instructions given by stereo_world and nhahtdh and then refresh your cache.
Thanks to Fabian and Doug for the groundwork. I just published an extension, which does exactly what you are trying to achieve in a clean way: https://github.com/customgento/CustomGento_AutoSelectImages
It simply adds a JS file on the admin product edit page. In the JS file, the mentioned method Product.Gallery.createImageRow is wrapped, so that the radio buttons can be selected after the first image has been uploaded. Here is the JS "magic":
if (typeof Product.Gallery !== 'undefined') {
Product.Gallery.prototype.createImageRow = Product.Gallery.prototype.createImageRow.wrap(function (parentMethod, image) {
// first call the parent method
parentMethod(image);
// auto-select the radio buttons for the first uploaded image
$H(this.imageTypes).each(function (pair) {
if (this.images.length === 1) {
this.getFileElement(image.file, 'cell-' + pair.key + ' input').checked = true;
}
}.bind(this));
this.setProductImages(image.file);
});
}
I'm trying to change the default behavior of Drupal when adding an image through image field on a content type.
When you choose an image to assign to a node, it's not directly uploaded. You also need to click "upload" to display the preview of your image, and this is not really user friendly.
How can I change this (programmatically) to make Drupal start uploading directly the image after choosing the file.
Thank you for help
You can do it this way:
(function ($) {
Drupal.behaviors.autoUpload = {
attach: function(context, settings) {
$('.form-item input.form-submit[value=Upload]', context).hide();
$('.form-item input.form-file', context).change(function() {
$parent = $(this).closest('.form-item');
setTimeout(function() {
if(!$('.error', $parent).length) {
$('input.form-submit[value=Upload]', $parent).mousedown();
}
}, 100);
});
$('.form-item input.form-submit[value=Transférer]', context).hide();
$('.form-item input.form-file', context).change(function() {
$parent = $(this).closest('.form-item');
setTimeout(function() {
if(!$('.error', $parent).length) {
$('input.form-submit[value=Transférer]', $parent).mousedown();
}
}, 100);
});
}
};
})(jQuery);
This solution works with either english and french browsers. Unlike AutoUpload module, which only works on browsers configured in english. Note the [value=Upload] / [value=Upload] attribute
I found a similar post:
https://drupal.stackexchange.com/questions/31121/how-can-i-automatically-upload-images-on-file-selection-rather-than-pressing-the
It's exactly what I need..
You should be able to use http://drupal.org/project/imce for your needs.
I am not sure about the Image field but when I encountered this issue I decided letting users add images in body since it is a much easier option for durpal - When inserting images in text They will show immediately .
IMCE + filefield seems like a viable option for your direct needs,They do mention AJAX support.
