Outlook Calendar for Trello is Released

David E. CraigLeave a comment

I have really enjoyed writing this bit of code because it stretched from Trello API to Office 365 API, two of my favorite programming interfaces. This Power-Up is similar to the default Trello Calendar Power-up, the key difference being is that it connects to your Outlook Calendar. So, you can see all your Trello Tasks and your Outlook appointments/meetings, side by side in one place, you can link your appointments to Trello cards and vice-versa. With a month view and a weekly view, you can manage your calendar easily by dragging and dropping your Trello Cards on the calendar to create linked appointments for specific tasks all in one place.

Check it out here:

New Outlook Add-in: Send to Trello

David E. CraigLeave a comment

I have been using Trello for a while now and one of the features I have found most useful is to take an email I received and turn it into a Kanban item on my backlog to address later. This allows me to archive the email but keeps it on my “Trello radar” as I work at my own pace through my personal backlog.

Recently, Trello removed their add-in from the Microsoft Office store. If you have the add-in installed, you will see this error:

Well, since they say necessity is the mother of all invention and I really had to fill the gap as it is part of my routine, I rolled my own. 🤓 To add a degree of difficulty, I wrote this in VS Code in Linux running in Windows Subsystem for Linux (WSL). See my previous post. It was a fun exercise as I am on vacation and using the time tom learn new things, engage in self-improvement and relax (coding is relaxing to me 🤓🤓🤓). In the end, I learned something and created something for everyone to enjoy.

Say hello to the recently published: Send to Trello Outlook Add-in.

Give it a try and let me know what you think.

Disabling your Web Add-in if you have an Equivalent COM/VSTO Add-in

David E. Craig3 Comments

In previous post, I described how you can add code to your VSTO/COM add-in to disable your Web Add-in loaded from maniferst via the Office Portal:
Removing Web Add-in Ribbon Customization in Outlook for Windows (theofficecontext.com)

Well with Outlook for Windows, Office 365, version 16.0.13728.36136, you can now disable your Web Add-in via Policy settings.

Download Administrative Template files (ADMX/ADML) and Office Customization Tool for Microsoft 365 Apps for enterprise, Office 2019, and Office 2016 from Official Microsoft Download Center

Here is the path in the policy editor for this setting:

Once in the policy editor, you would set the value. If your OfficeJS Web Add-in has a GUID of {c5bc7737-0d79-4302-9e73-2a614941e914} and the COM add-in is called “My Full Featured Outlook Add-in“, you would set the values like this:

Specifically, the registry key it puts in place is this:

PATH: HKCU\SOFTWARE\Policies\Microsoft\Office\16.0\Outlook\addins\equivalentcomaddin
KEY (string/REG_SZ): {OfficeJS GUID}
VALUE: Prog.ID

For example, if I have an Outlook Web Add-in called “My Outlook Add-in” and it has the following manifest entry:

<?xml version="1.0" encoding="UTF-8"?>
<OfficeApp 
          xmlns="http://schemas.microsoft.com/office/appforoffice/1.1" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
          xmlns:bt="http://schemas.microsoft.com/office/officeappbasictypes/1.0" 
          xmlns:mailappor="http://schemas.microsoft.com/office/mailappversionoverrides/1.0" 
          xsi:type="MailApp">
	<Id>c5bc7737-0d79-4302-9e73-2a614941e914</Id>

Let’s say I have a full VSTO add-in called “My Full Featured Outlook Add-in” and it is registered as the following:

If you were to look at the Policy key after it is set you would have an entry like this:

KEY: {c5bc7737-0d79-4302-9e73-2a614941e914}
VALUE: My Full Featured Outlook Add-in

If it were an older traditional COM Add-in, like the top item: AccessAddin.DC, then it would look like this:

KEY: {c5bc7737-0d79-4302-9e73-2a614941e914}
VALUE: AccessAddin.DC

That is all you have to do if you have the newest builds of Outlook for Windows. 

NOTE: Coming later in the year, will be an option to add this entry to your Web Add-in Manifest file the way you can with Excel and Word. 
NOTE: This is all covered in the latest Office add-ins community call.

easyEws Updated to 1.0.20

David E. Craig2 Comments

This was more than a patch this time. It was a minor update to two functions:

  • sendMailItem
  • sendPlainTextEmailWithAttachment

There was an issue reported (#12) where the sendMailItem function was not working in IE11. This was because it was created to take an inline object (ES6). Well on IE11 (which only supports ES5), it broke.

So, I fixed sendMailItem to support ES5 and also took the opportunity to add two often requested features of this function:

  • It will now allow you to submit HTML body content or Text. It will also parse the HTML for you if you submit it as is.
  • It will also now allow you to send both file attachment (new), and mail item attachments (original).

Please see the documentation for more information on the updates to this function: https://github.com/davecra/easyEWS#sendMailItem

Also I updated the sendPlainTextEmailWithAttachment function. Under the covers this uses the sendMailItem function. So I had to update it to use the new format so it would work as well. There was no change to it’s features/functionality however.

I did not get to the last item I have had requests for:

  • ability to specify recipients as To/CC/BCC. I will update this at some future date. Also, please let me know if you would like to see this.

Overall, the goal is to have the sendMailItem() function be a full multi-purpose function at some point. It is almost there, but please keep the suggestions coming.

Script Lab for Outlook. Yeah!

David E. CraigLeave a comment

OMG! This is a day I have been waiting for.

I do a LOT of Outlook Web Add-in development. A lot. I have made the move from Visual Studio to Visual Studio Code, from C# to JavaScript and have not looked back. However, there are a few things that make development in this new area difficult and that is rapid prototyping.

For C#, I could always go into VBA and see how the object model would behave when I needed to test a hypothesis. I was able to use VBA as a laboratory for ideas before I codified them into solid C# code in a VSTO Add-in. But there was no such laboratory in the JavaScript web add-in world, until now…

…Script Lab for Outlook has been released. And the best part, it is available in Outlook on Windows, Outlook on Mac and Outlook on the web!

Script Lab in Outlook for Windows
Script Lab for OWA

If you do a lot of Outlook development this will be a godsend. You will now be able to go into Script Lab and test your code ideas before you add them to your more complex add-in.

Open Outlook, go into the Office Store and type “Script Lab” and Script Lab for Outlook should come up in your list. Select and install it. Then open a message in Outlook and you should see the Script Lab items on the Home tab.

Happy coding!

Detecting Print in Outlook (VSTO/C#)

David E. Craig1 Comment

This is a common problem in Outlook. You might have tried to override the Ribbon settings for Print in Outlook to find that your code never gets run when the user clicks Print.

There is also not any events in the Outlook object model to detect Print either. So if you need to detect the user pressing the print button, you are out of luck.

While it is still not possible to detect the print button being pressed, you can at least detect when the user has selected the Print tab on the backstage.

The following code uses a background thread and a series of Windows API calls to FindWindow/FindWindowEx to detect when the Print tab on the backstage is opened:

[DllImport("user32.dll")]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll", SetLastError = true)]
public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle);
/// <summary>
/// Startup for Outlook Add-in
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
// we start by creating a background thread and look for a specific
// set of windows to appear, then we know the user clicked print
new Thread(() =>
{
while (true)
{
Thread.Sleep(1000);
CheckForPrint();
}
}).Start();
}
/// <summary>
/// Checks to see if the user has opened backstage and
/// selected the Print tab
/// </summary>
private void CheckForPrint()
{
try
{
// depending on whether we have an inspector active, or the explorer
// active we will need to get the caption to FindWindow
string LstrCaption = "";
if(Application.ActiveWindow() is Outlook.Inspector)
{
// Active inspector caption
LstrCaption = ((Outlook.Inspector)Application.ActiveWindow()).Caption;
}
else if(Application.ActiveWindow() is Outlook.Explorer)
{
// Active explorer caption
LstrCaption = ((Outlook.Explorer)Application.ActiveWindow()).Caption;
}
// get the window handle
IntPtr LintHostHandle = FindWindow(null, LstrCaption);
if (LintHostHandle == IntPtr.Zero) return; // if we cannot find it – nevermind
// create a list of windows to find (in reverse order)
// 4) rctrl_renwnd32 – is the print preview window
// 3) NetUICtrlNotifySink – is whole Print options and preview
// 2) NetUIHWND – is the the entire print tab
// 1) FullpageUIHost – is the backstage page
Stack<string> LobjWindowClasses = new Stack<string> (
new string[] { "rctrl_renwnd32", "NetUICtrlNotifySink", "NetUIHWND", "FullpageUIHost" });
// recursive call back to find each window in the stack.
// if all of them are found, then present a message to the user
if(FindWindowStack(LintHostHandle, LobjWindowClasses))
{
MessageBox.Show("You have clicked on the Print Tab in Outlook.");
}
}
catch { }
}
/// <summary>
/// RECURSIVE
/// This function will take the window classnames in the provided stack

IntPtr LintNewHandle = FindWindowEx(PintHandle, IntPtr.Zero, PobjStack.Pop(), "");
if(LintNewHandle != IntPtr.Zero && PobjStack.Count == 0)
{
return true; // found it
}
else if(LintNewHandle!= IntPtr.Zero)
{
// found a window, but the stack still has items, call next one
return FindWindowStack(LintNewHandle, PobjStack);
}
else
{
// did not find it
return false;
}
}
catch
{
// oops
return false;
}
}

easyEws v1.0.16 Published

David E. CraigLeave a comment

I have made a few minor updates to easyEws. First, was a fix for distribution lists with an “&” in the name. The second is a few minor JSDoc updates for better linting. And finally, I changed a couple forEach loops to traditional for loops for performance reasons.

I have published the update to NPM and to my GitHub.

Please let me know if you have any issues or questions.
