(3) How to use Office in Silverlight applications

Lista postări despre Office interop pe Silverlight:
Si iată ca am ajuns la ultimul post din seria de 3 posturi despre Office Interop pe Silverlight.
Am rămas dator cu doua topice:
  • cum sa închidem un proces office;
  • cum sa scriem unit teste;
Pentru a putea închide procesul pe care îl avem pornit ajunge sa apelam direct metoda Quit(). Atenție, când se apelează aceasta metoda orice modificare deja făcuta nu o sa fie salvata. Pentru a putea face și save trebuie sa apelam și metoda metoda de salvare:
excelApp.Save();
excelApp.Quit();
In cazul în care dorim sa închidem doar un document separat putem sa apelam la metoda Close, care poate sa fie accesibila pentru fiecare document separat.

Testarea automata a unei aplicații care lucrează direct cu interop-ul de Office este destul de dificila. De exemplu cum putem sa testam dacă un document a fost deschis și este vizibil user-ului? Trebuie sa verificam ca avem în Windows o fereastra deschisa (lista de procese pornite în Windows nu este relevanta în acest caz).
Cu cat flow-ul dintre user și interop-ul de Office se bazează direct pe editarea documentelor direct dintr-o fereastra de Office, cu atât testarea este mai dificila. In cazul în care deschidem documentele Office pentru a editate sau vizualiza documente direct din aplicația noastră, atunci testarea este mult mai sigura, și mai ușor de făcut. Iar partea de mock pentru interop o sa fie mult mai ușor de scris.
Cea mai mare problema care poate sa apară este în momentul în care deschidem un document de doua ori, din doua procese separate, iar al doilea proces nu o sa poată sa facă save. In cazul în care pățim acest lucru și nu avem o referința la primul proces nu recomand sa închidem forțat primul proces care face lock pe document, deoarece s-ar putea ca userul sa îl fi deschis manual.

Why Database Modernization Matters for AI

  When companies transition to the cloud, they typically begin with applications and virtual machines, which is often the easier part of the process. The actual complexity arises later when databases are moved. To save time and effort, cloud adoption is more of a cloud migration in an IaaS manner, fulfilling current, but not future needs. Even organisations that are already in the cloud find that their databases, although “migrated,” are not genuinely modernised. This disparity becomes particularly evident when they begin to explore AI technologies. Understanding Modernisation Beyond Migration Database modernisation is distinct from merely relocating an outdated database to Azure. It's about making your data layer ready for future needs, like automation, real-time analytics, and AI capabilities. AI needs high throughput, which can be achieved using native DB cloud capabilities. When your database runs in a traditional setup (even hosted in the cloud), in that case, you will enc...

Cloud Myths: Migrating to the cloud is quick and easy (Pill 2 of 5 / Cloud Pills)

The idea that migration to the cloud is simple, straightforward and rapid is a wrong assumption. It’s a common misconception of business stakeholders that generates delays, budget overruns and technical dept. A migration requires laborious planning, technical expertise and a rigorous process.  Migrations, especially cloud migrations, are not one-size-fits-all journeys. One of the most critical steps is under evaluation, under budget and under consideration. The evaluation phase, where existing infrastructure, applications, database, network and the end-to-end estate are evaluated and mapped to a cloud strategy, is crucial to ensure the success of cloud migration. Additional factors such as security, compliance, and system dependencies increase the complexity of cloud migration.  A misconception regarding lift-and-shits is that they are fast and cheap. Moving applications to the cloud without changes does not provide the capability to optimise costs and performance, leading to ...

Cloud Myths: Cloud is Cheaper (Pill 1 of 5 / Cloud Pills)

Cloud Myths: Cloud is Cheaper (Pill 1 of 5 / Cloud Pills) The idea that moving to the cloud reduces the costs is a common misconception. The cloud infrastructure provides flexibility, scalability, and better CAPEX, but it does not guarantee lower costs without proper optimisation and management of the cloud services and infrastructure. Idle and unused resources, overprovisioning, oversize databases, and unnecessary data transfer can increase running costs. The regional pricing mode, multi-cloud complexity, and cost variety add extra complexity to the cost function. Cloud adoption without a cost governance strategy can result in unexpected expenses. Improper usage, combined with a pay-as-you-go model, can result in a nightmare for business stakeholders who cannot track and manage the monthly costs. Cloud-native services such as AI services, managed databases, and analytics platforms are powerful, provide out-of-the-shelve capabilities, and increase business agility and innovation. H...
