Don not post the same thing in two different places: it duplicates work and annoys people.
You have this in QA, leave it there.

Hi,
I've 4 years experience in C# with Winfroms,wpf,silverlight. I placed my goal as become good technical architect in next two years. If you know the route map to reach, please guide me, where to start.

Learn?

What you say?, i could not understand.

Study & practice, practice, practice. There is no simple route map, since it largely depends on your skills, experience and ability to learn.

Thank you Mr. @Richard . But what i have to study. I accept there is no simple rute map. but the map is there am right?. The peoples who are in that position they know, thay can guid where we can start. What are the things i have to study and what are the skills i have to improve. Guide me.

You are in the wrong place, this is a technical forum for C# questions.
If you want to become a technical architect you first need to decide which field you are going to specialise in and study the subjects that make up that field. As to the skills, you need to be an above average programmer, with a thorough understanding of the language(s) and framework(s) that you will work on. You need to be a good analyst who can identify the steps needed to turn a business problem into a discrete set of steps for automation. And you need to be a methodical problem solver, for those occasions when everyone comes to you to ask why things don't work.

my two cents.
experience goes above studying. (Which doesn't mean studying is not important.)
If you can try to be involved in more complex systems and preferably in systems where applications start interacting with one another be it through messages, database or an API.
I ussually try to map out the system in my head (or literally in VISIO or something). Even if I only have to design part of it.
My main goals in defining a system are:
- data flows (where is data saved, where does it come from, can anything go wrong?)
- "boxes" not boxing/unboxing, but encapsulating problems, creating frameworks, services, layers.
Anything to keep a problem as simple as possible. If the problem is too complex, divide it in subproblems.
- How can I figure out what went wrong (and fix it with the least impact possible)
- Who can touch it, who uses it and how?
...
for me, being an architect is more of seeing the big picture and working down from there, taking in account the pittfalls if I go down. The technology only comes in when you get down low enough.
To write down my design I use a plain old word document (and visio, excel, ...), but pre-defined as a template with chapters as define objects, define issues/risks, define hardware, define security, ...
You can also use methodologies like UML, ...
but again, experience is key. Probably you'll need to ask your boss to change from "software developer" to "technical analyst" first, which is similar to architect, but on a lower level basis.
Hope this helps.
(PS: for the record, I have 10 years of experience, but I wouldn't even call myself an architect, rather an experienced technical analyst  )

Thanks a lot @V. But when we interacting with particular problem or system, before we must be qualified with technologies and its frequent updation right?
|

Architect is one of those terms that doesn't have a specific meaning. The route there involves picking up knowledge and skills in technical aspects (i.e. writing code and dealing with source control, CI etc), knowledge of frameworks and different technologies (part of designing a system is deciding what technology to deploy), and skills in breaking down a problem into parts and designing the parts and interactions between them.
Most of that will come from working with people who do it already.

Hi friends,
I have to use domino mail server in my c# winform app.
but when ı searched I must add reference dll file. but ı cant find this file. I think I must install some files, but ı couldnt found it. Can you help me?

From that little? Probably not.
But...reading here: http://stackoverflow.com/questions/8644955/send-mail-using-c-sharp-and-lotus-notes-using-client[^] suggests that it isn't a .NET assembly (which would be understandable) so you would need to use interop and DLLImport.
Not tried it as I won't allow BloatusGoats anywhere near my pc...

Don't repost your question again and again all over the site. Once is enough.
I've never heard of anyone doing what you're attempting, so I can't comment on it.

hi,
I wanted to ask is there a universal api to connect to any or to many databases from MySQL, MS SQL to Oracle, etc without having to change the sqlConnection, sqlCommand, etc for every different database?
I am asking this question because my application will hjave an option to connect to MS SQL, MySQL or Oracle.
Please advise...
Thanks,
Jassim

Yeah, it's called ODBC.
The problem with it is that it's not optimized to connect to any one database type, and hence, performance suffers a bit.
The way it's normally done is you create a database provider layer for your application supporting the connection to the database type that's chosen. This is where a tiered application design approach comes in.
