I'm curious what some methods being used are and which ones work for you. I've worked with SVN, TFS, and currently/unfortunately VSS. I've seen version control implemented very poorly and just OK, but never great.
Just to get the ball rolling, here is a review of things I've seen.
This example is SVN-based, but applies to most VCS's.
1. branch the individual projects that are part of site
/division/web/projectName/vb/src/[trunk|branches|tags]
2. branch the whole site, in the case I've seen, the whole site except for core components was branched.
/division/[trunk|branches|tags]/web/projectName/vb/src/
3. Use main-line a default, only branch when necessary for **huge** changes. | version-control | null | null | null | null | null | open | Structure of Projects in Version Control

I love it, but there is one tiny thing that is annoying to me about this feature: *the window stays around after releasing the ctrl key*. When doing an alt-tab in windows, you can hit tab to get to the item you want (while still holding down the alt key), and then when you find what you want, *lifting up* on the alt key selects that item.
I wish VS 2008 would do the same. For me, when I lift off of ctrl, the window is still there. I have to hit enter to actually select the item. I find this annoying.

- Experienced guys in Delphi and/or COM, do you have any workrounds to work with the buggy TLB interface ?
Some of the bugs are: IDE crashing during edition of a large TLB, lost of methods IDs, TLB corruption, etc.
Here, we haven't found any good solution. Actually we tried do upgrade do the new 2007 version. But the new IDE TLB interface has the same bugs that we found before.
- How do you control TLBs versions ? The TLB file is in a binary format and conflict resolutions are very hard to do. We tried to do it exporting the interfaces descriptions to IDL and commiting into CVS, but we didn't found any good way to generate TLBs from IDL using Delphi. Additionaly, the MIDL tool provided by Microsoft, didn't parse correctly the IDL files that we exported from delphi.

This is undesirable since we are using [CruiseControl][1] to do an automatic daily build and this is causing false build failures.
As a quick-and-dirty solution I have created 2 separate tasks, compiling portions of the project in each. I really don't think this solution will hold as more classes are added in the future, and I don't want to be adding new compile tasks every time we hit the "compile limit".

We have one solution with multiple applications, multiple dependencies. We're on SourceSafe currently and are planning to move to subversion but are finding it difficult to organize our source the right way.

We also have a configuration management system which deploys (via copy from database) depending on which workload the operator is working. We mark an application "release" with a version and to that release we add multiple file dependencies. Bear in mind the solution we have in place now is an attempt to band-aid the old (windows 3.1 developed) solution to work with .NET file/dependency structure.
In the case of App1 we have App1.exe, BizObjects.dll, DataAccess.dll, and CustomControls.dll.
We have the same set of dependencies for App2 due to BizObjects referencing DataAccess -- but this is defined manually. We don't have a system in place to identify the dependency tree.
Each of the dependencies for a "release" is a file and version id. And the same application could contain different versions for each file for a different workload.
1. Where in the world have we gone wrong? Did we go wrong?
2. How can we structure a svn source tree to accommodate the deployment requirements?
- or
3. how can we re-structure the code the better support a deployment strategy which makes sense for our setup?
We have an old and over-engineered solution to (it would seem) a relatively simple problem. Can anyone steer me/us in the right direction?

I find a multi-monitor setup indispensable both in the office and at home (for hobby development). Since I start dividing my time 50/50 between development and management I'm beginning to feel that I'm doing a lot more Alt+Tabbing and am considering a third monitor.
On that note - aside from installing a second graphics card are there any other solutions for a triple monitor setup?

int doMoreWonderfulThings(const int* fantasticData)
{
if(!fantasticData)
return ERROR_VALUE;
// ...
return AHA_VALUE;
}
TEST(TDD_Enjoy)
{
ASSERT_EQ(ERROR_VALUE, doMoreWonderfulThings(0L));
ASSERT_EQ(AHA_VALUE, doMoreWonderfulThings("Foo"));
}
Just with my experiences first approaches let me remove so many subtle bugs.
But TDD approaches are very smart idea to handle legacy codes.
"Google" - they compare "FIRST METHOD" to "Walk the shore with life-vest, swim ocean without any safe guard".
Which one is better?
Which one makes software robust?

<table>
<tr><th>Category</th><th>Revenue</th><th>Yearh</th><th>Month</th></tr>
<tr><td>Bikes</td><td>10 000</td><td>2008</td><td>1</td>
<tr><td>Bikes</td><td>12 000</td><td>2008</td><td>2</td>

<tr><td>Bikes</td><td>15 400</td><td>2007</td><td>4</td>
</table>
<br/>
... And so forth
The view has a product category, a revenue, a year and a month. I want to create a report comparing 2007 and 2008, showing 0 for the months with no sales. So the report should look something like this:
<table>
<tr><th>Category</th><th>Month</th><th>Revenue This Year</th><th>Revenue Last Year</th></tr>
<tr><td>Bikes</td><td>1</td><td>10 000</td><td>0</td></tr>
<tr><td>Bikes</td><td>2</td><td>12 000</td><td>11 000</td></tr>
<tr><td>Bikes</td><td>3</td><td>12 000</td><td>11 500</td></tr>
<tr><td>Bikes</td><td>4</td><td>0</td><td>15 400</td></tr>
</table>
<br/>
The key thing to notice is how month 1 only has sales in 2008, and therefore is 0 for 2007. Also, month 4 only has no sales in 2008, hence the 0, while it has sales in 2007 and still show up.
Also, the report is actually for financial year - so I would love to have empty columns with 0 in both if there was no sales in say month 5 for either 2007 or 2008.
The query I got looks something like this:
SELECT
SP1.Program,
SP1.Year,
SP1.Month,
SP1.TotalRevenue,
IsNull(SP2.TotalRevenue, 0) AS LastYearTotalRevenue
FROM PVMonthlyStatusReport AS SP1
LEFT OUTER JOIN PVMonthlyStatusReport AS SP2 ON
SP1.Program = SP2.Program AND
SP2.Year = SP1.Year - 1 AND
SP1.Month = SP2.Month
WHERE
SP1.Program = 'Bikes' AND
SP1.Category = @Category AND
(SP1.Year >= @FinancialYear AND SP1.Year <= @FinancialYear + 1) AND
((SP1.Year = @FinancialYear AND SP1.Month > 6) OR
(SP1.Year = @FinancialYear + 1 AND SP1.Month <= 6))
ORDER BY SP1.Year, SP1.Month
The problem with this query is that it would not return the fourth row in my example data above, since we didn't have any sales in 2008, but we actually did in 2007.
This is probably a common query/problem, but my SQL is rusty after doing front-end development for so long. Any help is greatly appreciated!
Oh, btw, I'm using SQL 2005 for this query so if there are any helpful new features that might help me let me know. | sql | database | query | reporting | null | null | open | SQL query to compare product sales by month

Hi All,
OK, further into my adventures with custom controls...
In summary, here is that I have learned of three main "classes" of custom controls. Please feel free to correct me if any of this is wrong!
1. **UserControls** - Which inherit from _UserControl_ and are contained within an _ASCX_ file. These are pretty limited in what they can do, but are a quick and light way to get some UI commonality with designer support.
2. **Custom Composite Controls** - These are controls that inherit from _WebControl_ where you add pre-existing controls to the control within the _CreateChildControls_ method. This provides great flexibility, but lack of designer support without additional coding. They are highly portable though since they can be compiled into a DLL.
3. **Custom Rendered Controls** - Similar to Custom Composite Controls, these are added to a Web Control Library project. The rendering of the control is completely controlled by the programmer by overriding the _Render_ method.
##My Thoughts..
OK, so while playing with custom composites, I found the following:
* You have little/no control over the HTML output making it difficult to "debug".
* The _CreateChildControls_ (and subsequent methods) can get real busy with _Controls.Add(myControl)_ everywhere.
* I found rendering tables (be it for layout or content) to be considerably awkward.
##The Question(s)..
So, I admit, I am new to this so I could be way off-base with some of my points noted above..
* Do you use Composites?
* Do you have any neat tricks to control the HTML output?
* Do you just say "to hell with it" and go ahead and create a custom rendered control?
**Its something I am keen to get really firm in my mind since I know how much _good_ control development can cut overall development time.**
I look forward to your answers ^_^ | c# | .net | asp.net | controls | usercontrols | null | open | ASP.NET Custom Controls - Composites

The problem is that CryptEncrypt can produce NULL's in the output, meaning that when it's stored in the database, the string manipulations will at some point truncate the ciphertext.
Ideally we'd like to use an algo that will produce cyphertext that doesn't contain NULLs as that will cause the least amount of change to the existing databases (changing a column from string to binary and code to deal with binary instead of strings) and just decrypt existing data and re-encrypt with the new algo at database upgrade time.
The algorithm doesn't need to be the most secure, as the database is already in a reasonably secure environment (not an open network / teh interwebs) but does need to bebetter than ROT13 (which I can almost decrypt in my head now!)

Since the web-viewer built into VisualSVN server is a minimalistic subversion browser, I'd like to install [WebSVN](http://websvn.tigris.org/) on top of my repositories.
The problem, however, is that I can't seem to get authentication to work. Ideally I'd like my current repository authentication as specified in VisualSVN to work with WebSVN, so that though I see all the repository names in WebSVN, I can't actually browse into them without the right credentials.

(the main blog page seems to have been destroyed, domain of the topmost page I'm referring to is the-wizzard.de)
There I found some php functions I could tack onto one of the php files in WebSVN. I followed the modifications there, but all I succeeded in doing was make WebSVN ask me for a username and password and no matter what I input, it won't let me in.

Since the web-viewer built into VisualSVN server is a minimalistic subversion browser, I'd like to install [WebSVN](http://websvn.tigris.org/) on top of my repositories.
The problem, however, is that I can't seem to get authentication to work. Ideally I'd like my current repository authentication as specified in VisualSVN to work with WebSVN, so that though I see all the repository names in WebSVN, I can't actually browse into them without the right credentials.
By visiting the cached copy of the topmost link on [this google query](http://www.google.com/search?q=WebSVN+authentication+with+IIS+and+VisualSVN) you can see what I've found so far that looks promising.
(the main blog page seems to have been destroyed, domain of the topmost page I'm referring to is the-wizzard.de)
There I found some php functions I could tack onto one of the php files in WebSVN. I followed the modifications there, but all I succeeded in doing was make WebSVN ask me for a username and password and no matter what I input, it won't let me in.
Unfortunately, php and apache is largely black magic to me.
So, has anyone successfully integrated WebSVN with VisualSVN hosted repositories? | 0 |

OK, following on from my other question on [ASP.NET Web Service Results, Proxy Classes and Type Conversion](http://stackoverflow.com/questions/6681/aspnet-web-service-results-proxy-classes-and-type-conversion). I've come to a part in my project where I need to get my thinking cap on.
Basically, we have a large, complex custom object that needs to be returned from a Web Service and consumed in the client application.
Now, based on the previous discussion, we know this is going to then take the form of the proxy class(es) as the return type. To overcome this, we need to basically copy the properties from one to the other.
In this case, that is something that I would really, really, _really!_ like to avoid!
So, it got me thinking, **how else could we do this?**
My current thoughts are to enable the object for complete serialization to XML and then return the XML as a string from the Web Service. We then de-serialize at the client. This will mean a fair bit of attribute decorating, but at least the code at both endpoints will be light, namely by just using the .NET XML Serializer.

Obviously, each project is unique, so my question here is **not** so much **whether** assertions should be kept, **but in which cases** this is recommendable/not a good idea.
By assertion, I mean:
- A run-time check that tests a condition which, when false, reveals a bug in the software.
- A mechanism by which the program is halted (maybe after really minimal clean-up work).
I'm not necessarily talking about C or C++.
My own opinion is that if you're the programmer, but don't own the data (which is the case with most commercial desktop applications), you should keep them on, because a failing asssertion shows a bug, and you should not go on with a bug, with the risk of corrupting the user's data. This forces you to test strongly before you ship, and makes bugs more visible, thus easier to spot and fix.
What's your opinion/experience?
Cheers,
Carl
