void Foo(params object[] items)

When I pass two object arrays to this method, it works fine:

// Output: System.Object[]

From what Joel was saying, the first few steps are pretty standard:
1. One server running both the webserver and the database (the current Stackoverflow setup)
2. One webserver and one database server
3. Two load-balanced webservers and one database server
They didn't talk much about what comes next though. Do you add more webservers? Another database server? Replicate this three-machine cluster in a different datacenter for redundancy? Where does a web startup go from here in the hardware department?

At least, that's what I'm hoping for...
I don't want to wrap (practically) every single line in try...catch statements, so I think my best bet is to make a custom error handler for the beginning of my files.
I'm testing it out on a practice page:
function customError($level,$message,$file,$line,$context){
echo "Sorry, an error has occured on line $line.<br />";
echo "The function that caused the error says $message.<br />";
die();
}
set_error_handler("customError");
echo($imAFakeVariable);

===
I'm taking the leap: my php scripts will ALL fail gracefully!
At least, that's what I'm hoping for...
I don't want to wrap (practically) every single line in try...catch statements, so I think my best bet is to make a custom error handler for the beginning of my files.
I'm testing it out on a practice page:
function customError($level,$message,$file,$line,$context){
echo "Sorry, an error has occured on line $line.<br />";
echo "The function that caused the error says $message.<br />";
die();
}
set_error_handler("customError");
echo($imAFakeVariable);
This works fine, returning:

The idea is the user inputs a string that contains digits and the output should return only the digits.
So, if the user inputs
`te12abc` the output should be `12`.
This is my first try:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#define SIZE 10
int main()
{
char palavra[SIZE];
char palavra2[SIZE];
char *pont = palavra;
char *pont2 = palavra2;
printf("Insert the string\n");
scanf("%s", palavra);
do{
if (isdigit(*pont)){
strcat(palavra2, *pont);
}
*pont++;
}while (*pont != '\0');
printf("\nThe number is:\n%s\n", palavra2);
return 0;
}
I believe that the pointer is working as expected but can't understand why strcat is not working.
Made a second try that is the program finds a number, stores that char in one variable and only then try to use strcat with that variable. Here is the code:
int main()
{
char palavra[SIZE];
char palavra2[SIZE];
char temp;
char *pont = palavra;
char * pont2 = &temp;
printf("Insert the string\n");
scanf("%s", palavra);
do{
if (isdigit(*pont)){
temp = *pont;
strcat(palavra2, pont2);
}
*pont++;
}while (*pont != '\0');
printf("\nThe number is:\n%s\n", palavra2);
return 0;
}
Once again it gives me problems at strcat.
Made one last attempt but without pointer and still strcat does not work. Here is the code:
int main()
{
int i = 0;
char palavra[SIZE];
char palavra2[SIZE];
char temp;
printf("Insert the string\n");
scanf("%s", palavra);
do{
if (isdigit(palavra[i])){
temp = palavra[i];
strcat(palavra2, palavra[i]);
}
i++;
}while (palavra[i] != '\0');
printf("\nThe number is:\n%s\n", palavra2);

#define MAX_INDEX 8
int GetStuff(IN char* index[MAX_INDEX], OUT char* buf, IN size_t size);
The first argument is populated with pointers into the buf argument where specific strings are stored. The size indicates how long each string is expected to be in the buf buffer. My C# P/Invoke method for this currently looks like this:
[DllImport("Path/To/Dll", CharSet = CharSet.Ansi)]
private static extern int GetStuff(IntPtr indecies, IntPtr buf, Int32 size);
The C# P/Invoke method is private because I'm wrapping it's functionality in a public "getter" method which handles the allocation/deallocation of memory for the caller. When I use this method in C++, iterating is quite simple actually. I simply do something like:
char* pIndecies[MAX_INDEX];
char* pBuffer = new char[MAX_INDEX * 256 + 1]; // +1 for terminating NULL
GetStuff(pIndecies, pBuffer, 256);
// iterate over the items
for(int i(0); i < MAX_INDEX; i++) {
if(pIndecies[i]) {
std::cout << "String for index: " << i << " " << pIndecies[i] << std::endl;
}
}
Because of how these are used in C++, I decided I should probably use IntPtr objects and just allocate the memory that I'll need from the heap, call into the native code, and iterate over it the way I would in C++. Then I remembered that chars in C# are unicode characters and not ASCII characters. Would iteration in C# work the same even if I placed the iteration in an unsafe code block? My first thought was to do the following:
IntPtr pIndecies = Marshal.AllocHGlobal(MAX_INDEX * 4); // the size of a 32-pointer
IntPtr pBuffer = Marshal.AllocHGlobal(MAX_INDEX * 256 + 1); // should be the same
NativeMethods.GetStuff(pIndecies, pBuffer, 256);
unsafe {
char* pCStrings = (char*)pIndecies.ToPointer();
for(int i = 0; i < MAX_INDEX; i++) {
if(pCStrings[i])
string s = pCStrings[i];
}
}
My question then is, "How should I iterate over what this native code method returns?" Is this the right way to marshal to this function? Should I use a StringBuilder object for the second argument? One constraining problem is that the first argument is a 1:1 mapping of a structure behind the GetStuff() method. The value of each index is crucial for understanding what you're looking at in the second buffer argument.
I appreciate any suggestions.

I have a dynamically created image that I am saving to a stream so that I can display it on a ReportViewer surface.
Setup:
* Report datasource is an object datasource, with a dynamically generated stream as a property (CustomImage)
* Report.EnableExternalImages = true
* Image.Source = Database
* Image.MIMEType = image/png
* Image.Value = =Fields!CustomImage.Value
This is not working, but is not reporting any errors, just showing an empty image icon on the report surface. All other fields are displaying correctly.
Does anyone have a working code sample of this scenario?

The line should start with a `$` sign, and end with an `*` and a two character hex checksum. I don't care if the checksum is correct, just that it's present. It also needs to ignore "ADVER" sentences which don't have the checksum and are at the start of every file.

This was a pretty good backup system, and allowed me easily work on any of the machines. I could checkout a specific project, commit and it updated the 'master' project, or I could checkout the entire thing.
Now, I have a bunch of git repositories, for various projects, several of which are on github. I also have the SVN repository I mentioned, imported via the git-svn command..
Basically, I like having all my code (not just projects, but random snippets and scripts, some things like my CV, articles I've written, websites I've made and so on) in one big repository I can easily clone onto remote machines, or memory-sticks/harddrives as backup.
The problem is, since it's a private repository, and git doesn't allow checking out of a specific folder (that I could push to github as a separate project, but have the changes appear in both the master-repo, and the sub-repos)
I *could* use the git submodule system, but it doesn't act how I want it too (submodules are pointers to other repositories, and don't really contain the actual code, so it's useless for backup)
Currently I have a folder of git-repos (for example, ~/code_projects/proj1/.git/ ~/code_projects/proj2/.git/), and after doing changes to proj1 I do `git push github`, then I copy the files into ~/Documents/code/python/projects/proj1/ and do a single commit (instead of the numerous ones in the individual repos).

We have had several cases with ~25,000 rows, which works relatively smoothly, but a potential customer needs to have many times that much in a single list.
To figure out how well we scale right now, and how (and how far) we can realistically improve, I'd like to implement a simulation: instead of displaying actual data, have the SQL Server send fictional, random data. The client and transport side would be mostly the same; the view (or at least the underlying table) would of course work differently. The user specifies the amount of fictional rows (e.g. 100,000).
For the time being, I just want to know how long it takes for the client to retrieve and process the data and is just about ready to display it.
What I'm trying to figure out is this: how do I make the SQL Server send such data?
Do I:
1. Create a stored procedure that has to be run beforehand to fill an actual table?
2. Create a function that I point the view to, thus having the server generate the data 'live'?
3. Somehow replicate and/or randomize existing data?
The first option sounds to me like it would yield the results closest to the real world. Because the data is actually 'physically there', the `SELECT` query would be quite similar performance-wise to one on real data. However, it taxes the server with an otherwise meaningless operation. The fake data would also be backed up, as it would live in one and the same database — unless, of course, I delete the data after each benchmark run.
The second and third option tax the server *while* running the actual simulation, thus potentially giving unrealistically slow results.
-----
In addition, I'm unsure how to create those rows, short of using a loop or cursor. I can use `SELECT top <n> random1(), random2(), […] FROM foo` if `foo` actually happens to have `<n>` entries, but otherwise I'll (obviously) only get as many rows as `foo` happens to have.

I have been playing around with the Windows API and came across a couple of examples on how to initialize create windows and such.

wndClass.cbSize = sizeof( wndClass );
wndClass.style = CS_HREDRAW | CS_VREDRAW;

// Create dialog box
DialogBox(hInstance,

The second example does not contain any call to the register function. It just creates the DialogBox with its DialogProc process attached.
This works fine, but I am wondering if there is a benefit of registering the window class and then creating the dialog box (if this is at all possible).

// Create dialog box
DialogBox(hInstance,
MAKEINTRESOURCE(IDD_MAIN_DLG),
NULL,
(DLGPROC)DialogProc);
}
</pre>
The second example does not contain any call to the register function. It just creates the DialogBox with its DialogProc process attached.
This works fine, but I am wondering if there is a benefit of registering the window class and then creating the dialog box (if this is at all possible).

As a means of improving my lacking skills in this area, I have started a [project](http://Telharmonium.devjavu.com/) to create an Eclipse-based front-end for [xmms2](http://xmms2.xmms.se).
I've implemented a protocol abstraction which I call ['client'](http://telharmonium.devjavu.com/browser/trunk/xmms2-client) (for legacy reasons) which allows me to access most exposed features using method calls which I am happy with even if it's far from perfect.
The features provided by the xmms2 daemon are things like track searching, meta-data retrieval and manipulation, change playback state, load playlists and so on and so forth.
I'm in the middle of updating to the latest stable release of xmms2, and I figured I might as well fix some of the glaring weaknesses of my current implementation.
My plan is to build a better abstraction on top of the protocol interface, one that allows a more natural interaction with the daemon. The current ['model'](http://telharmonium.devjavu.com/browser/trunk/xmms2-model) implementation is hard to use and is frankly quite ugly (not to mention the UI-code which is truly horrible atm).
So, the question is; how should I expose the remote interface as a neat data model (In particular track management and event handling)?
Today I have the [Tracks](http://telharmonium.devjavu.com/browser/trunk/xmms2-model/src/se/fnord/xmms2/model/Tracks.java) interface which I can use to get instances of [Track](http://telharmonium.devjavu.com/browser/trunk/xmms2-model/src/se/fnord/xmms2/model/Track.java) classes based on their id. Searching is performed through the [Collections](http://telharmonium.devjavu.com/browser/trunk/xmms2-model/src/se/fnord/xmms2/model/Collections.java) interface (unfortunate namespace clash) which I'd rather move to Tracks, I think.
Any data can be modified by a third party at any time, and this should be properly reflected in the model and change-notifications distributed
These interfaces are exposed when connecting, by returning an object hierarchy that looks like this:
* Connection
* Playback getPlayback()
* Play, pause, jump, current track etc
* Expose playback state changes
* Tracks getTracks()
* Track getTrack(id) etc
* Expose track updates
* Collections getCollection()
* Load and manipulate playlists or named collections
* Query media library
* Expose collection updates
I welcome anything from generic discussions to pattern name-dropping or concrete examples and patches :)

We often read textbooks & novels linearly, perhaps taking notes along the way. What do you do when trying to understand how a program works?
* Try the user-facing version of the program with your own inputs
* Read the API
* Trace through the core functions in your head, transforming imaginary inputs
* Start at "main" and fire off the debugger!
I read the Ruby on Rails source code when I studied the [MVC pattern][2]. Many discussions leave out critical parts of MVC as done in Rails:
* The **web server** negotiating the communication with the browser (the controller's HTML output has to get to the browser somehow)
* The **dispatcher** translating the incoming HTTP request to function parameters and instantiating the controller (you don't want this logic in the web server!)
When people say MVC they really mean "MVC + the subsystem to run it". Since I'd used Rails for a while before digging in, I had an idea of what to expect but this was nevertheless enlightening. But if I had never touched Rails (or MVC) and used it for a few projects I wouldn't be sure where to start.
I'm curious: How do you go about understanding the source for a project?

[Reading source code][1] is a good way to improve as a programmer, but I've never seen a great explanation of how to do it. We often read textbooks & novels linearly, perhaps taking notes along the way. What do you do when trying to understand how a program works?
* Try the user-facing version of the program with your own inputs
* Read the API
* Trace through the core functions in your head, transforming imaginary inputs
* Start at "main" and fire off the debugger!
I read the Ruby on Rails source code when I studied the [MVC pattern][2]. Many discussions leave out critical parts of MVC as done in Rails:
* The **web server** negotiating the communication with the browser (the controller's HTML output has to get to the browser somehow)
* The **dispatcher** translating the incoming HTTP request to function parameters and instantiating the controller (you don't want this logic in the web server!)
When people say MVC they really mean "MVC + the subsystem to run it". Since I'd used Rails for a while before digging in, I had an idea of what to expect but this was nevertheless enlightening. But if I had never touched Rails (or MVC) and used it for a few projects I wouldn't be sure where to start.
