Although Delphi has served me very well in the past I now only use it for this one application and find my skills with the language diminishing. It's syntax is too different from my 'day job' languages of Java/Ruby so it takes me longer to get into the groove of writing new code, plus it is so old I have not used many **interface**s so the code is not managed which seems ancient to me now!
Many of my users are moving to Vista which may run the app in compatibility mode or may have GPF problems depending on how their PC is configured by their IT department, so I have to do some maintenance on the application. I'm wondering if I should jump to a more familiar stack.
Is there an automated tool that will do the legwork of converting the code base to C#, leaving me to concentrate on the conversion on any non-standard components? I'm using an embedded database component called [AbsoluteDatabase][1] which is BDE compatible and using standard SQL throughout, and a native Delphi HTML browser component which can be swapped out with something from the Microsoft world.
How good are these conversion tools?

I personally don't like my applications in Hebrew, since I'm used to the English UI conventions embedded in me since long ago by:
1. **The lack of choice:** Most programs don't offer interfaces in multiple languages and when they do, those languages are usually English and the developer's native tongue.
2. **Programming languages** which are almost completely bound to the English language.
My question then is this:
1. If you translate your applications, would you limit the UI to the user's native tongue or give them the choice by enabling more than one language pack by default?
2. Which language would your application default to (which is interesting mostly if you only install one language pack with your application)?

There is occasional support for development from contractors, but for the most part, if code is written in the office, I am writing it.
Many of the articles and such on here talk extensively about the tools and techniques used for collaboration of developers in teams, but that is a non-issue with me, as there is no one to (technically) collaborate with. Yet, I feel that in many ways, there are things that could be adjusted for efficiency. Our small office doesn't participate in many of the meetings/team constructions that most of the techniques rely heavily upon....we mostly just walk around and talk to one another when something is needed.
This works great for all of the Just-In-Time, 15 minute fix stuff that probably populates 50% of my day, but I am also constantly working on major projects that require my total concentration, and between a flurry of tiny fixes, and being the primary admin on the 4-6 servers that we own, I find it almost impossible to get real, heavy lifting done.
What suggestions can you some of you offer to help me/us become more productive/efficient, without adopting all of the corporate/teamwork practices that we are trying desperately to avoid? At what cost for efficiency is our total relaxation? | productivity | performance | solo-developer | null | null | null | open | What tools/techniques can benefit a solo developer?

When should the lock be used?
For instance it makes sense with multi-threaded applications because it protects the data. But is it necessary when the application does not spin off any other threads?
Is there performance issues with using lock?
I have just inherited an application that is using lock everywhere, and it is single threaded and I want to know should I leave them in, are they even necessary?
Please note this is more of a general knowledge question, the application speed is fine, I want to know if that is a good design pattern to follow in the future or should this be avoided unless absolutely needed. | c# | locking | designpatterns | null | null | null | open | lock keyword in C#

Pre-SP1, this was working fine (and still works fine on our developer machines). Now that we've done some testing post-SP1 I've been pulling my hair out since yesterday morning.
First off, our NSIS installer script pulls the dlls and manifest files from the redist folder. These were no longer correct, as the app still links to the RTM version.
So I added the define for <code>\_BIND\_TO\_CURRENT\_VCLIBS\_VERSION=1</code> to all of our projects so that they will use the SP1 DLLs in the redist folder (or subsequent ones as new service packs come out). It took me hours to find this.
I've double checked the generated manifest files in the intermediate files folder from the compilation, and they correctly list the 9.0.30729.1 SP1 versions. I've double and triple checked depends on a clean machine: it all links to the local dlls with no errors.
Running the app still gets the following error:
>>The application failed to initialize properly (0xc0150002). Click on OK to terminate the application.
None of the searches I've done on google or microsoft have come up with anything that relates to my specific issues (but there are hits back to 2005 with this error message).
Any one had any similar problem with SP1?
Options:<ul>
<li>Find the problem and fix it so it works as it should (preferred)

I'm using a brute force method, where the computer generates some random daily polling data and then calculates three day averages to see if the average of the random data matches pollsters numbers. (Most companies poll numbers are three day averages)
Currently, it works well for one iteration, but my goal is to have it produce the most common simulation that matches the average polling data. I could then change the code of anywhere from 1 to 1000 iterations.
And this is my problem. At the end of the test I have an array in a single variable that looks something like this:
[40.1, 39.4, 56.7, 60.0, 20.0 ..... 19.0]
The program currently produces one array for each correct simulation. *I can store each array in a single variable, but I then have to have a program that could generate 1 to 1000 variables depending on how many iterations I requested!?*
How do I avoid this? I know there is an intelligent way of doing this that doesn't require the program to generate variables to store arrays depending on how many simulations I want.
Thanks,

I want to turn the screen off when the user places his iphone upside down on q desk. At the same time I do not want to have the proximity monitor enabled all the time as this is very uncomfortable for the user and miss fires a lot of times depending on how you grab the device.

I am thinking of is to use the accelerometer to determin if the face is down, if so activate the proximity censor. Simple stuff...

In practice the workaround does not work, It seams that if the censor is "occluded" when you activate it, it will not register its current state.

The most common method for corrupting compressed files is to inadvertently do an ASCII-mode FTP transfer, which causes a many-to-one trashing of CR and/or LF characters.

The tests on my development machine have shown the average load time to be between 3 and 5 seconds, during which the application is totally locked. While this isn't totally unacceptable, it's an awfully long time to lose control of the application. Also, because the GUI thread is locked, I cannot show a loading dialog or something to mask the load time.

axMappointControl1.NewMap(MapPoint.GeoMapRegion.geoMapNorthAmerica);
I've tried executing the NewMap method on another thread but the GUI thread still ends up being blocked.
My questions are:
- What can I do to speed up MapPoint when it loads?
- Is there any way to load MapPoint so that it won't block the GUI thread?

If the querysource you do the contains with has more than 10 items in it, it does not pass the items correctly to the SQL query. It is hard to explain what it does, an example will show it best.
If you look at the raw query, the parameters look like this:
@P0 = 'aaa'
@P1 = 'bbb'
@P2 = 'ccc'
... [@P3 through @P9]
@P10 = '111'
@P11 = '222'
... [@p12 through @P19]
@P20 = 'sss'
... [@P21 through @P99]
@P100 = 'qqq'
when the values are passed into the final query (all parameters resolved) it has resolved the parameters as if these were the values passed:
@P0 = 'aaa'
@P1 = 'bbb'
@P2 = 'ccc'
...
@P10 = 'bbb'0
@P11 = 'bbb'1
...
@P20 = 'ccc'0
...
@P100 = 'bbb'00
So it looks like the parameter resolving looks at the first digit only after the @P and resolves that, then adds on anything left at the end of the parameter name.
At least that is what the Sql Server Query Visualizer plugin to Visual Studio shows the query doing.
Really strange.

In the past for projects that required encryption, I encrypted/decrypted in the application code. However, this was generally for encrypting passwords or credit card information, so only a handful of columns in a couple tables. For this application, far more columns in several tables need to be encrypted, so I suspect pushing the encryption responsibilities into the data layer will be better performing, especially given MSSQL 2005's native support for several encryption types. (I could be convinced otherwise if anyone has real, empirical evidence.)
I've consulted BOL, and I'm fairly adept at using google. So I don't want links to online articles or MSDN documentation (its likely I've already read it).
One approach I've wrapped my head around so far is to use a symmetric key which is opened using a certificate.
So the one time setup steps are (performed by a DBA in theory):
1. Create a Master Key
2. Backup the Master Key to a file, burn to CD and store off site.
3. Open the Master Key and create a certificate.
4. Backup the certificate to a file, burn to CD and store off site.
5. Create the Symmetric key with encryption algorithm of choice using the certificate.
Then anytime a stored procedure (or a human user via Management Studio) needs to access encrypted data you have to first open the symmetric key, execute any tsql statements or batches, and then close the symmetric key.
Then as far as the asp.net application is concerned, and in my case the application code's data access layer, the data encryption is entirely transparent.
So my questions are:
1. Do I want to open, execute tsql statements/batches, and then close the symmetric key all within the sproc? The danger I see is, what if something goes wrong with the tsql execution, and code sproc execution never reaches the statement that closes the key. I assume this means the key will remain open until sql kills the SPID that sproc executed on.
2. Should I instead consider making three database calls for any given procedure I need to execute (only when encryption is necessary)? One database call to open the key, a second call to execute the sproc, and a third call to close the key. (Each call wrapped in its own try catch loop in order to maximize the odds that an open key ultimately is closed.)
3. Any considerations should I need to use client side transactions (meaning my code is the client, and initiates a transaction, executes several sprocs, and then commits the transaction assuming success)?

* Adding more functionality

So let's say a class instantiates another class, that class instance is now referenced with an object. From that child object, what is the best way to reference back to the parent object? Currently I know of a couple ways that I use often, but I'm not sure if A) there is a better way to do it or B) which of them is the better practice
The first method is to use getDefinitionByName, which would not instantiate that class, but allow access to anything inside of it that was publicly declared.
_class:Class = getDefinitionByName("com.site.Class") as Class;
And then reference that variable based on its parent to child hierarchy.
Example, if the child is attempting to reference a class that's two levels up from itself:
_class(parent.parent).function();
This seems to work fine, but you are required to know the level at which the child is at compared to the level of the parent you are attempting to access.
I can also get the following statement to trace out [object ClassName] into Flash's output.
trace(Class);
I'm not 100% on the implementation of that line, I haven't persued it as a way to reference an object outside of the current object I'm in.
Another method I've seen used is to simply pass a reference to this into the class object you are creating and just catch it with a constructor argument
var class:Class = new Class(this);
and then in the Class file
public function Class(objectRef:Object) {
_parentRef = objectRef;
}
That reference also requires you to step back up using the child to parent hierarchy though.
I could also import that class, and then use the direct filepath to reference a method inside of that class, regardless of its the parent or not.
import com.site.Class;
com.site.Class.method();
Of course there the parent to child relationship is irrelevant because I'm accessing the method or property directly through the imported class.
I just feel like I'm missing something really obvious here. I'm basically looking for confirmation if these are the correct ways to reference the parent, and if so which is the most ideal, or am I over-looking something else?

I have an ASP.Net application that has a couple hundred users. Aspects of it are fairly processor intensive, but thus far we have done fine with only one server to run both SqlServer and the site. It's running Windows Server 2003, 3.4 GHz with 3.5 GB of RAM.
But lately I've started to notice slows at various times, and I was wondering what's the best way to determine if the server is overloaded by the usage of the application or if I need to do something to fix the application (I don't really want to spend a lot of time hunting down little optimizations if I'm just expecting too much from the box). | asp.net | webserver | null | null | null | null | open | Best way to determine the number of servers needed

I have a single command-line based executable that performs some unit of work. I want to call that executable with the .net process library, as I can do with any other executable.
However, it dawned on me that there is potential for the dll to become useless or break with unintended updates to the executable or a non-existant executable.
Is it possible to run the executable from the Process object in the .net framework, as I would an external executable file? | .net | command-line | dll | resources | null | null | open | Is it possible to embed and use a portable executable in a .net DLL?

CREATE TABLE Parent (id BIGINT NOT NULL,
PRIMARY KEY (id)) ENGINE=InnoDB;
CREATE TABLE Child (id BIGINT NOT NULL,
parentid BIGINT NOT NULL,
PRIMARY KEY (id),
KEY (parentid),
CONSTRAINT fk_parent FOREIGN KEY (parentid) REFERENCES Parent (id) ON DELETE CASCADE) ENGINE=InnoDB;

CONSTRAINT fk_child FOREIGN KEY (childid) REFERENCES Child (id)) ENGINE=InnoDB;
Notice there is no ON DELETE CASCADE for the Uncle-Child relationship; i.e. deleting a Child does not delete its Uncle(s) and vice-versa.
When I have a Parent and an Uncle with the same Child, and I delete the Parent, it *seems* like InnoDB should be able to just "figure it out" and let the cascade ripple through the whole family (i.e. deleting the Parent deletes the Uncle and the Child as well). However, instead, I get the following:
ERROR 1451 (23000): Cannot delete or update a parent row: a foreign key constraint fails (`cascade_test/uncle`, CONSTRAINT `fk_child` FOREIGN KEY (`childid`) REFERENCES `child` (`id`))
InnoDB is trying to cascade-delete the Child before the Uncle(s) that refer to it.
Am I missing something? Is this *supposed* to fail for some reason I don't understand? Or is there some trick to making it work (or is it a bug in MySQL)? | mysql | database-design | innodb | null | null | null | open | In what order are ON DELETE CASCADE constraints processed?
