My first 10 days into EA14 have passed by and I am discovering some issues ranging from nuisances to real distractors … So here is my list of bugs and SO questions. I will update the list as I receive updates from Sparx or other sources. CaseId 18058962 – confirmed Package Validation in Enterprise Architect […]
Enterprise Architect allows you to create custom document templates to be used in your reports. Internally EA uses the oldie-goldie RTF document format for these templates. When exporting these templates via Export Reference Data they are included as base64 encoded zipped RTF documents which in turn are again base64 encoded. For the untrained eye it […]
It has been some time since I have last posted something on our blog, so I will start with something easy: today I made the switch from Sparx Enterprise Architect v13.5 to v14.0. And yes, it really paid off since I now can actually decipher all those small connector icons on my Surface Book 2 […]
After playing around with the Office 365/Exchange 2016 REST API I decided to summarize the knowledge and the experiences I gained in this blog post. The goal of the tryout session was to check out the Outlook endpoints for messages and calendars. To be more precise, I wanted to try out the following features. Reading […]
One of the requirements our WPF project had to meet describes the ability to create a sketch of the sewage shaft for which data is collected. The functional acceptance criteria are the following. There has to be an area on the form to create a sketch of the sewage shaft using Surface Pen, touchscreen or […]
When we used ListBox controls in our WPF project we faced the same problem as described in the previous post. Like DataGrid, ListBox control also has a property called SelectedItems, which isn’t a dependency property and therefore not bindable too. This post shows how ListBox control can be extended with a bindable version of the […]
According to MVVM pattern the ViewModel interacts with the Model but doesn’t know anything about its View. As a result dependency properties of controls get bound to ViewModel properties by specifying bindings in the corresponding View (XAML). DataGrid control has a property called SelectedItems, which in multi selection mode holds the items that are selected. […]
As we often use Data Annotations for basic validation purposes in context of C#/.NET applications (i.e. required, max length, …), we searched for a solution that allows using Data Annotations in WPF ViewModels for client side validation. Fortunately we found such a solution, which I would like to describe in this blog post. Implement IDataErrorInfo […]
Today my boss asked me to extend the session lifetime for Outlook Web App to have a lower login frequency. As described in the article Session timeouts for Office 365 the session timeout is set to 6 hours by default. To change the session timeout the following steps have to be executed. Connect to Exchange […]
While developing an UWP application I wanted to log unhandled exceptions. My coach mentioned that in WPF you can register a exception handler to handle unhandled exceptions globally. In UWP it works exactly the same way. Add Unhandled Exception Handler NOTE: This solution does not prevent your app from crashing and exiting. This solution only […]
