• Architecture Serviced component architecture issues (State management/ OOD).

  I've seen serviced components abused and misused due to inherent limitations in how COM operates and now I’m looking to architect a web based, OO, n-tier system and wish to avoid the same mistakes. In my system there are two architectural problems: Much of the data is common across users, complex and potentially quite large, which leads to a large number of objects when using standard OOD (not so good for COM as I understand). Some (but not all) update requests need to be processed in serial, all others concurrently. I’m considering a windows service application that can hold all the user independent dat ...Show All

• SQL Server SSIS: Inserting unknown members from fact table

  Looking up surrogate keys in a dimension table and adding these to your data flow is easy when there is a match in your dimension table for every key in your fact table. However, I am puzzled by how to manage the data flow when no match can be found for a specific key in the fact table when doing the lookup AND I then want to insert this unknown key as an unknown/inferred member in the dimension table. The problem is further complicated by the fact that when I have inserted the unknown member in the dimension table and it has been assigned a surrogate key there, I want to add this surrogate key to my fact table - just as if there h ...Show All

• Visual C# Increase Memory Pressure for Garbage Collection

  Dear all, I would like to ask if any API or efficient way for making GC run more frequently, without calling GC.Collect() What I am doing is I am checking if the objects are referenced by other objects, by using weak references. Unfortunately, it was found that as the latest made forms had not been garbage collected yet, and the Target in the weak reference still showed the object. I tried to increase the memory pressure by composing new garbages, but not successful. I found some posts saying that it is possible to increase CLR memory pressure for acheive this Is it right If yes, how to implement Thx a lot! Gabriel ...Show All

  My app plays sounds when it is running and works fine on my WinXP machines but when I use it on a Win98 machine it doesn't produce any sound.

• Windows Forms Draw on the screen itself

  Hello, Is there a way to draw a pixel or a graphic out side of my form so maybe even though my form (200px by 200px in size) is placed on 400,400 on the screen... But maybe I would like to draw a pixel on 10,10 on the screen, NOT the form... so that the pixel will be OUT of the form.. If any answers are available, it would be very appriciated! Thank You Keehun Nam Yes there is, but I would discourage you to use it. Use a p/invoke to GetDC with NULL as parameter.

• SQL Server How to stop a package

  Hi, In one of my packages, I have a script component to do a transformation and I am inserting the output to table. Within that script component, if the data does not match my requirement, I have to stop the job. For that, I am using 'componentmetadata.fireError' to raise an error. The problem is, now even when an error is raised, the job completes by loading the remaining records and then aborts. But I want to abort the job as soon it raises an error. How to do this Thanks. HI, sorry to jump in. But I looked in books online and did not found a way to stop the package in the dataflow using the system cancel variable. Is there a w ...Show All
