Hi,
I've done a couple of syntax colorizers, most of them without using a RichTextBox at all.
RTB is rather slow, as it performs complex parsing and formatting jobs, and requires all text to be concatenated.
Here is what I typically do:
- implement the colorizer logic on my own data structures, tailored for that purpose;
- store each line in a separate object, all of them in a list;
- a line would consist of the text itself, plus some extra information, e.g. "this line opens a multi-line comment", "this line closes a multi-line comment", etc.
- scan the document from start till current view point to determine state (e.g. am I in the middle of a
multi-line comment)
- only execute the actual coloring logic on visible lines (that is a few dozen, whatever the size of the current document is)
- and when the output were an RTB, I would probably generate the RTF string myself, rather than doing lots of selections and modifications.

GIDS is India's Biggest Polyglot Conference for Software Developer Professionals
Bangalore, March 25, 2010: Every year, Great Indian Developer Summit is a game changer for several thousands of IT professionals, providing them with a competitive edge over their peers, enlightening them with bleeding-edge information most useful in their daily jobs, helping them network with world-class experts and visionaries, and providing them with a much needed thrust in their careers. At GIDS 2010, to be held 20-23 April in Bangalore, Vice Presidents of Goldman Sachs' technology division speaks about acceptance test driven development and collections renaissance.
Acceptance test driven development can work really well. Users give their requirements as inputs and a table of results, and you can show them directly that they are done. John Tobin and Mohammed Mohsinali of Goldman Sachs say FitNesse, an open-source framework from ObjectMentor, is a great tool for this. Users can put their expected results in a wiki, press the page test button and see results. At GIDS, on the 22nd of April, John and Mohammed will conduct an example-driven session on FitNesse and how it can be used in large, business-critical applications.
In another session, Vlad Zakharov and Donald Raab will dwell on Java collection frameworks, why is there a sudden emergence of frameworks and what should you look for in a collections framework. They will explain the historical perspective – from the pre-Java days through the dark ages of early Java to today's collections renaissance. How the "minimal interface" philosophy of the Java API has lead to some unfortunate decisions. Why modern languages all have closures, and how the "humane interface" is fighting back. You will see examples of the power and simplicity you can bring to your code, and find out how to design collections classes. After this session, you will never look at a for loop in the same way again.
With several decades of software development experience between them, the speakers are a powerhouse of knowledge on software development and the ICT industry. John Tobin has extensive Java enterprise development experience with companies ranging from start-ups through product companies to large global corporations. A Vice President at Goldman Sachs Technology Division, he is particularly interested in reducing development time and production issues by building the partnership with users. Mohammed has several years of experience in developing enterprise oriented software. Mohammed is a VP at Goldman Sachs Technology Division and is focused on developing framework components to enable users to complete their tasks in an efficient and effective manner.
Vlad Zakharov, a VP at Goldman Sachs' Technology Division, has programmed in Java, Smalltalk and a number of other more obscure languages. His areas of expertise include application architecture, object-oriented analysis and design, and software development. Donald Raab has 20 years of experience in technology and software development and is a VP at Goldman Sachs' Technology Division. He has programmed in Java, Visual Basic, Smalltalk, and a number of other more obscure languages. His areas of expertise include application architecture, object-oriented analysis and design, Test Driven Development, and collections framework design and implementation.
From 20th to 23rd April 2010, immerse yourself in over 80 sessions from the world of Rich Web, Java and Microsoft computing technologies at India's biggest polyglot conference for Software developers. Attend Great Indian Developer Summit to gain the information, education and solutions you seek. From post-conference workshops, breakout sessions by expert instructors, keynotes by industry heavyweights, enhanced networking opportunities, and more.

Create a new Win32 project and select static lib or dll in the project type page. VS2005 will set the build options automatically to build the selected library type.

Just add the library to your Linker options in the project properties. Obviously time to go through either the VS help files or the entire properties lists to get familiar with some of the basics.

Don't remove questions if they already got replies, it results in a messy forum. See the forum guidelines.
Your original post was:
hi ,
can anyone tell me how to build an object file library in VS2005 framework.
for ex :libBasicUsageEnvironment.lib, how to build this library..?
i am a newbie to .net . kindly help me

one of my spiders takes a snapshot of www.codeproject.com on an hourly base;
and a second one posts replies to the questions that match some filter criteria.
More seriously, yes there are ways to see what isn't there any more. I only use it to tell them of though.

i am having a doubt on the Difference between the Tier and layer architecture ????
Thanks and regards
Mahendran Chandramohan
|
|
|
|

I don't know what the definition says in the books, but.. Different tiers often run on different machines (client/server etc), whereas layers (DAL, BL, CL, UI) are often on the same machine.
The UI-layer sometimes becomes a tier, if that makes sense
I are Troll

|

Wrong forum for your question....this is the .Net framework forum.
Layers means way to organizing the code logically not physically. Tiers means code separation on network or process boundaries.
|
|
|
|

It is a grey area. It appears that many articles use the terms tier and layer interchangeably.
Some people distinguish the two as multi-layer describing the separation of code into functional areas such as GUI, Business Logic and Data Access; and multi-tier describing a physical separation by process boundary, sometime accompanied by distribution of the tiers on separate hardware. This distinction is moot, as the code in each tier is the same code as in each layer, just separated by process boundary. Therefore a multi-tier application is also multi-layer, and many multi-layer applications are multi-tier. I would argue that whether or not there is a process separation is irrelevant, and often confuses matters. The big question from an architectural point of view is are you using a client-server architecture.
Multi-tier architecture[^]

Hi
I've noticed a performance problem in my application. My application does some calculation inside a 'for' loop and show that answer on the canvas. When I minimize the application it executes fast.If it is in maximized then it takes too much time to finish the for loop.
Inside the for loop I've used Control.Invalidate(). Will it make the performance changes when it is minimized and maximized?
Thank You.
Regards,
R.Sumanan

|

Absolutely.
Control.Invalidate causes the visible portions of the control to redraw. As the app is minimised there is therefore nothing for it to do at that point. When maximised the work load increases due to paint event processing. You will get the same effect by bringing another window to the front of the display stack.
Unless you really need to show the calculation in progress don't invalidate until you have finished processing.
|
|
|
|
|
It's exactly the same if the form was minimized or not.
Invalidate does NOT cause the control to be repainted. Invalidate (simplified description) tells Windows that the control NEEDS to be repainted and (optionally) what region of the control needs it. Windows will eventually send a WM_PAINT message to the app's message pump which will eventually get around to your control so it can repaint the specified region of the control. If the control is not visible, the WM_PAINT message doesn't get processed, so no painting gets done.

Hi!
I have a Motorola MC7090 that runs a .Net Compact Framework - application.
On the mainform i catch the "KeyDown"-Event, which work fine for "regular" keys.
As the MC7090 (as most Windows Mobile devices) has some custom keys, two for volume (+/-) on the left side, and another key on the right side.
When i open the application i get a key-down-event from this key on the right side.
After klicking a button on the touchscreen the event is not longer thrown.
All other keys (keypad 1-9, etc...) work fine.
Just this one key is not working.
Unfortunately my customner wants exacly this key to work.
Does anyone have any idea how i could make this key work?
Thanx!
J.

Try overriding WndProc and checking for the message manually?
|
|
|
|
|
That was my emergency-solution.
The big question is why an event is raised in the beginning, but not after a button was pressed...
That´s kind of strange to me...

Hi folks 
Would higly appreciate your help on this.
Suppose a C# Windows Service is running with some domain user login/password...
Now suppose the user's password expires...
Will the service keep running? or will it stop as soon as the password expires?
|
|
|
|
|
I don't know for sure but I would suspect the service will continue to run since it had already started and authenticated, however, if it restarts it should not.

Domain services should run under the Network service account or a domain account with no password expiry duration. If you use any other account service will stop running not start once the password expires.

are you sure? It seems to me it would keep running until restarted. The process has already been started and I'm not aware of a mechanism that continues to check if the service has been authenticated

Yes. It won't happen suddenly. But it will not run start once password is expired.
Still, I guess it would depend on the kind of the service. I guess if the service tries to do any kind of file operations, since the account has already expired it should not be allowed to.

Makes sense to me also.
