Hi Leslie,
I would suggest you add an options dialog, that lets the user choose the maximum capture
period (say radio buttons for 10 sec, 1 min, 10 min; or a textbox); then have the record
button record to memory for that time (or until clicked again), then do the save/saveto
dialog stuff you described.
I would not automatically save to temp file on disk, unless you take some precautions
limiting both the size and the number of such files; without limits, you may find yourself
cleaning up the disk quite often.

That sounds excellent. Will do. Thanks!

Glad to help.
The more challenging option could be: record for ... sec/min
or [checkbox] until 3 sec of silence occurs.

Also, you could add in support for both. This way for people who wish to record large amounts they have the option of recording to hard disk. But also include a restraint option in the config dialog similar to what you'll have for in memory recording.
This statement was never false.

Hello guys, i'd like to implement the undo and redo function(like Undo and Redo in MS Word) by combination Command and Memento design pattern. I've found a quite useful article about this but it did not mention Memento.Can anyone tell me how to combine these two design pattern?I've also searched around but these articles are either about Command or Memento not both of them.
Thank you

It's not common to combine the two patterns to perform Undo/Redo. I would suppose that you would need to identify against each action whether or not it was specified with a Memento or a Command. This is not a good design.
Deja View - the feeling that you've seen this post before.

Had this question in the wrong forum.
I'm at a breakpoint with my architecture and could use some guidance in finishing up my vision. I will give a rundown of the current architecture so far:
This is a plug-in architecture, that automates the loading and un loading of plug-ins for the users and developers. By using a defined interface and custom attributes my architecture will auto load plug-ins without the use of ini files or configuration files.
The current issue I have is security and applying security filters to screens as they display. What basically will happen is an admin will setup security and access points for roles. Roles are then assigned to a user. What I need is to be able to disable, hide, unhide or re-enable elements on the form at the time the page is loaded based on that users security role. This is simple if I have every developer call a set of security procedures, but what I want is the framework to automatically do this for the developer.
The one idea so far is the use of “Application Event Handler” which is looking for a certain windows message to be sent.
I was wondering if anyone else had any other ideas that might be worth looking into. ( IE: any patterns or such)
Thanks for the Help.

Class Diagrams? That is what the code is generated from.

I'd suggest asking on Ibm's rose forum.

Hallo,
my company works on Rational Suit 2003
if you created the class digram, you should open it then go to tools menu,and select the programming language, then you can see the Create Code option, select it, so the code will be generated if there is no errors in your digram.
Best Wishes, Good Luck

We have a section of our application that deals with reporting, using MS reporting services. We also have a custom data extension that performs some post processing on the datasets returned (basically stripping out records that the runtime user would not be authorised to see).
The current method we are using is to run the sql, generate a dataset, check to see if it contains sensitive data (looking at column names) and then loop through the rows, removing those that are not required.
Obviously, this is a lot slower than it would be to just alter the sql to remove these rows using criteria in the where clause, but we can't see a way to robustly parse the sql to establish
A) That the query is actually accessing sensitive data.
B) Where we can insert our chunk of sql into the where clause.
For simple reports, this is relatively easy, but as some of the reports are considerably more complex and the sql will contain calls to functions and in some cases creating temp tables, it rapidly becomes more complex.
So, the question - does anyone know of a robust method of taking a string of arbitrary sql and parsing to allow us to alter the where clause of whichever part of it returns data?

I don't have a real solution for your problem but a simple idea.
After reading your message I assume that you know the structure of the result (schema).
Therefore it should be possible to wrap your query:
select <only permitted="" columns="">
from <the original="" query="">where <additional restrictions="">
This way you can get rid of the unwanted data on the db server.

no risk no funk

No, and this is really the problem, the sql that we are passed could contain largely anything.

I'm not sure if this is the right place to ask, I think it is, but feel free to move it mr(s) admin if need to be to somewhere more appropriate.
I was really just after peoples thoughts, so here goes....If I have a page/area divided up into subareas but these are changeable in size what would be the best way to do it? I was thinking originally about just drawing lines (having the x/y of the start point and the length), but then throught its not really the line I'm interested in but the area it encloses so I suppose I would want to be able to draw boxes (similar to divs in a webpage is the best way of decribing it, its basically for laying out information within the application but allowing the user to resize areas) so I would need x/y and w/h. Would that be a more sensible approach ? Or ...(and heres hoping  is there something already within the windows api that would handle this - some sort of table type structure would probably do it, just so long as i could return the values of each of the cells. Could I do something with multiple panels maybe, I'd need to maintain the coords etc of them but at least that would give me something *physical* to work with, suppose I should go and play around a bit and see what comes of it.
anyway, like I said it was really just to see if anyone thought I was barking up the wrong tree, had completely missed something that was out there or thought maybe i was going in the right direction.
cheers

You don't say what you're using. In WinForms, .NET 2.0, you can use a nested set of SplitContainer controls to host whatever else you need in the divisions you mention.

hi brady
sorry, i suppose that might have helped....doh!
SplitContainer controls sound exactly like the thing I was after, I knew there'd be something rather than me bodging in some sort of tawdry effort that only kind of half works.
thanks for the pointer

I was arguing with my friends about sending the business object over a web service.
Some of my friends said that they don't pass the busineess object (eg: Employee ) to Webservice. Instead, they used to pass the individual parameter (eg: empId, empName, empAddress ) to WebService. Because they think that sending the business object over a webservice is not good practice.
I don't understand why this is not good practice. I used to send the custom business object to webservice in several project. It works fine.. Plus, it's so easy if I wanna add some properties (eg: empPhone, empEMail ) to my business object because I dont need to add the individual parameter in each and every webmethods whenever I made changes to my BO.
I'd like to hear your opinion about this. What do you think?
Thanks in advance.

Nope - your business object is the way that I'd go. As long as it's serializable, you should be fine. I suspect that they are thinking along the lines that the serialized object is going to be much more information that individual parameters, and hence is going to take more bandwidth - but if you are dealing with corporate systems this tends not to be too much of an issue.
Really, you've got to ensure that your business object doesn't grow to be too big and balance this with the convenience of passing this over.

That is not really tracking for me. There is not really a "object" approach to WebServces. There are really only Two types and then of course the REST approach which in now considered a Third type. The two main types are RPC versus Document Centric (now referred to as Service Oriented Architecture as in this definition[^])
Anyway if what you guys are arguing about is RPC vs Document Centric, the RPC approach has been recognized as inferior for a few years now as pointed out in that Wikipedia page.

OK - I let the last one pass, but I've got to point out to you that this is a forum and Design and Architecture. How does your query relate to this in any way?
