I have a form ( dialog ) that shows (among other things ) a simple Edit box and a Button to browse ( calls a file selector )
What should I show to the user in the Edit Box ?
The complete filename ( path and extension : c:\\MyPath\\MyFilename.Extension )
Only the filename ? With or without the extension ? ( MyFilename.Extension or MyFilename )
Should the Edit box be editable ?
The issue I have right now is that if I show the complete filename, and the user decide to type only a name ( no path or extension ) what should be the behaviour ?
Reject the filename and warn the user ?
Try to build a default path with the default extension ?
Thanks.

Have an edit box for the path, filled initially with some good default path
Have another edit box for the file name
have a third for the extension (defaulted as for the path)
when the user changes either the path or extension, save the changes as new defaults
Use a static/label to display the full path

Dear All,
We need to create an application for folder selection dialog and we have creted using SHBrowseForFolder concept.Using this concept we were able to compile and run the application in Emulator.Whereas when we are trying to run the application in CEPC(x86 processor), it just hangs and shows the message as "Unknown: DEBUGCHK failed in file C:\WINCE500\PUBLIC\SHELL\OAK\HPC\CESHELL\API\.\api.cpp at line 385".It happens when the application issues the api SHBrowseForFolder.Can anyone suggest an idea to solve this problem.
Thanks in Advance.

This really isn't the forum for this. Try the C++ forums instead.

Hi,
I have to come up with the architecture for very uncommon (by my opinion) framework:
1)I have to develop the MAPI store provider module for Outlook 2000/2007. This MAPI store provider has to be done with C++ (ATL) since Microsoft does not officially support .NET on MAPI store provider site.
2)There is the “data adapter” which has to supply the actual data to MAPI store provider (folders, list view, columns and more). This “adapter” has to be done on .NET/C# . The data could be retrieved from different data sources by “data adapter”. This could be the database, the file system or even web.
3)The .NET based “data adapter” has to be also flexible enough to supply data to different clients (I call them extensions), such as MAPI store provider, Windows explorer extension, Pocket PC and more.
In the COM word (which I know much better then .NET) I could design such architecture as a COM based MAPI store provider, COM based Windows explorer extension and COM based out-of-process server which will be the data source for “client site” extensions. I have a hard time making a decision regarding of the architecture which involves .NET data adapter. The problem here is the fact that:
1)I need the .NET replacement for COM based out-off-process server.
2)Connect C++ based MAPI provider with .NET out of process “data adapter”. I could use the C++/CLI in order to connect the MAPI store provider to “data adapter” component, but preferably NO .NET on the MAPI store provider site - it should be pure COM based.
3)The protocol between the data adapter and the client site should be really fast.
4)The replacement of COM based out-of process server (data adapter) should provide data to many concurrently running clients (Win Explorer and MAPI provider/Outlook for example)
The framework could be developed with any available .NET version - I just need the fastest way to communicate between COM based client and .NET out-of-process replacement.
I would really appreciate if you have some code example of such architecture for performances measurement (at least one C++/COM based client connected to .NET based “off-process” server).
Regards,
Dmitry

Hi,
The "Paint" application that is bundled with Windows distributions
is not open-source, so nobody will give you the sources.
Anyway, you can take a look at the Paint.NET:
http://www.getpaint.net/download.html
It is open-source, whole project is monitored by Microsoft,
so it'll give you the idea on how graphics editor works.
Hope it helps,
- Dmitry.

Hiya all.
I'm currently trying to find some sources/feedback upon various methods of designing a database.
Up to now, the database design I've been working with have been relatively simple and thus not so difficult in modeling, but now I think I'll be faced with a more difficult project and thus am trying to find some inspiration.
If I have to map a large amount of products to a database, and each product can have a (large) amount of various attributes across multiple languages. The attributes for one product might not all be used for any other product and vice versa - so I'm ponding what would be the best way of doing this.
To simplify:
Supposed we have product X and Y and Z.
Product X have attributes A, B, C
Product Y have attributes D, E, F
Product Z have attributes A, B, F
Now multiply this up with a factor 50 per attribute and thousands of products over various languages and markets and we get the scope.
Now, how I usually handle attributes is to normalise them out into a seperate table and use a connection table for the value, so I have a table for product, attribute and attribute value entity with a key from the product and attribute.
Pretty standard I think....
However, with a scope like this, we'd be looking at a big table of attributes, products and then subsequently a very big table of values. This would/could seriously hamper the lookup times from the database.
An alternative method I could think off would be to make some sort of dynamic table creation, so each product when created, got a table assigned to itself with the attributes.
So I'd have a product table, and for each of these a currentProduct_attribute table which would contain all the values. This would provide a faster lookup, from what I can see at the expense of a very large number of tables and various administrative problems if a product is to be move/deleted etc.
Another alternative could be to integrate the attributes into the product table with additional fields there. It would however cause huge product table with many unused fields in each row. Alternative one could sort of "bitmap" the attributes in the product table.
Does anybody have any feedback or pointers - or possible references (please, if possible) I could take with me in my considerations?
I've tried googeling my problem, but it is difficult finding something concrete and some relevant keywords to search for.
Thanks in advance.

It seems you've got a handle on the three basic alternatives:
(1) A single table with all the attributes, many of the columns containing nulls in many of the rows.
(2) A single table with the common attributes and additional, separate tables for attributes specific to each product (or product type).
(3) A single table with the common attributes and an additional table keyed by product and attribute type with attribute value in a third non-key column.
The fact that you're having trouble deciding between these means that your application would probably benefit from a carefully crafted combination of the three. So, assuming you can't break the whole application into separate and consistent "subsystems", I would recommend that you:
Push as much as you can into option (1) - even if some nulls result. For many of the products, this may be all that is necessary, resulting in a simple and easy-to-query database of "basic" products; then
Add some option (2) tables for those products that are unique enough to warrant them - products with well-defined attributes that are likely to be queried. To minimize the number of addtional tables, allow yourself some nulls in the new tables as well. Finally,
Use option (3) for descriptive attributes that are less likely to be queried but are necessary primarily for display purposes.
Don't fall into the typical designer's trap that says a single storage paradigm is appropriate in all cases; this simply isn't true. A typical product catalog will contain items with descriptions only, some with descriptions and a table of measurements, some with descriptions, measurements, and special shipping instructions, etc. Think of how you would present the information on paper, and your thinking will clear up. A good carpenter will use a hammer here, a screwdriver there, and a chisel somewhere else - all on the same job.

Thanks for your feedback - it is very much valued from me 
So basically your suggestion to the problem is that I attempt to analyze which data is most used, and optimize the read/query of these while using more "traditionally/school example normalization" for the remainder, less used data?

Basically, yes, if I understand you correctly (and you've understood me). But...
The important thing is to think like your users and their customers, not like a developer. These people are simply trying to get something done: the customer wants to place an order, the user wants to fill it. Your job is to make that easy for them. They don't care about abstract database design considerations, normalization, etc. If you say to them, "this is handled differently than that because it is different" they won't object; but if you make them handle similar things in different ways, they will not be happy. Likewise, if you unnaturally force different things into a single mold they will think you are making things unnecessarily difficult (and they'd be right); only when things are essentially the same should they be treated the same.
I recommend, again, that you think in terms of a printed catalog with an order form inside. Get some catalogs - not websites, but real printed catalogs that someone has put some thought into - and look them over. Here in the States I would get a hardware catalog (Home Depot or Lowes), a media catalog (Circuit City or Media Play), a general-purpose catalog (Sears or Penny's), and perhaps an auto-parts catalog (Pep Boys). If my client already had a printed catalog, I would use that too - but I wouldn't limit myself to that. I would study the different kinds of items in the different catalogs and how they are presented. Then I would make up a similar catalog and order form for my application. By the time I was done, the form that the database should take would be obvious.

Yeah - I know the "thinking like..." and it is funny you should mention thinking from the perspective of a printing catalogue, as that is excatly what the scope of the project is, creating a new catalogue. So that is very much my approach to the situation/problem/project
The "problem" is however as mentioned, that the amount of data is very large with the variable attributes, so instead of attempting to fit it into some standard design (what I would label as "school/textboox solutions"), which I upfront would know are very sluggish and slow performing for extraction of this amount of data (however, would be easier to update and manage) - I am attempting to draw inspiration as to the various other methods of designing the database; such as pro and cons with dynamic table creation, many nullables in each row of a table and so on.
I'm attempting to keep it on a somewhat abstract level to better get the whole picture.
But as always - thanks for your feedback.

Our company, years ago, developed a program specifically designed to handle large amounts of printed information of all kinds in the simplest possible way - we call it a wysiwyg "pagebase" and since the pages themselves are the database, it is fast, efficient, easy to understand and use, etc - there is no "translation" from database format to viewing format and back, and the user's idea of the thing is identical to the developer's. We've been using it for all of our corporate data for almost ten years now.
I can send you a PDF of the documentation (about 100 pages) if you're interested in this kind of "inspiration", but you'll have to email me directly so I have a place to send it (you can use the email button below).

I need a user/password pair to connect to a RDBMS through my application.
Now I want to store those informations in a secure manner and I have thought to store them inside an encrypted archive using a strong encryption algorithm (may be AES, for example).
Now, what is the smartest way to store the encyption key needed to access the user/password pair ?
Inside the application binary ? In which secure way ?
Into another kind of container ?
Thanks

It's the same solution I have thought, in some way.
And now I'm reading some articles about DPAPI to see if it can help me for this kind of problems.
Thanks a lot

If you have .NET 2.0 it can do the encryption/decryption for you as well as store it in the registry I believe.

I'm using VC++ without managed code.
However it seems that DPAPI could solve this problem, either using a machine-store or a user store.
For the latter, a point is not clear for me:
for user-store it seems DPAPI use the windows user logon credentials to generate the master and session keys. The CryptProtectData and CryptUnprotectData functions have the chance to show a dialog to allow the user to insert a password. Is this only necessary if the windows user has no password set (may be a standalone machine) ?
