Brother DCP-145C printer problem

- by erkan

I have a Brother DCP-145C printer installed and it does not print black ink. I tried running diagnostics and test pages, the driver is installed properly. It doesn't matter if I send the data from the pc, or use the scanning function. What could be the problem? Printer is brand new by the way, should i return it?

web server and database server distance

- by Erkan

I want to seperate my server into two parts: web server and dbserver. My web server is located in Turkey and my dbserver is located in Germany. I cant change my web server because my agreement is based on my Ip adresses. I want to locate my dbserver in Germany because more cheap then Turkey. But... I have a problem in here. When you call a db action, first, you are going to Turkey for IIS and IIS is going to Germany for Dbserver. It is too far and so slow to response back. Any idea? Is it wrong that the distance is so far between web server and dbserver? Or Are there any solutions for this problem?

How to set default values to the properties of dynamically loaded types at runtime for XML serializa

- by Erkan Y.

I need to serialize dynamically loaded types' classes using XMLSerializer. When using XML serializer non initialized values are not being serialized. I dont have control over the assemblies I am working with so can not use XML attributes for specifying default values on properties. So I think I need to set all properties and sub properties to their default values recursively and then serialize. ( Please let me know if there is any better way ) Followed this : Activator.CreateInstance(propType); but above line complains about not having a parameterless constructor for some types. Tried this : subObject = FormatterServices.GetUninitializedObject(propType); but this one gives an error "value was invalid" with no inner exception. Please let me know if you need any further information.

Aggregate Functions in Index with IBMDB2

- by Erkan

Is there any way to pre aggregate results of aggregate functionts (f.i. count()) and store it in an index? The background is: i want to speed up count() queries. So that: Select count(users) from TE123 where region = 'A'; would be supported by an index like Region Count(Users) A 548 E 458 I know that MQTs would also help for this problem. However, in this case it is not possible to use MQT, as we use kind of an ORM and we don't want to define Entities on MQTs. I just slightly remember - one DBA told me - that there is such a function planned for DB2 V10.

Computing e^(-j) in C..

- by Erkan H

I need to compute imaginary exponential in C. As far as I know, there is no complex number library in C. It is possible to get e^x with exp(x) of math.h, but how can I compute the value of e^(-j), where j = sqrt(-1)?
