• Sending basic authentication information via form

  - by VolatileStorm

  I am working on a site that currently uses a basic authentication dialog box login system, that is the type of dialog that you get if you go here: http://www.dur.ac.uk/vm.boatclub/password/index.php I did not set this system up and am not in a position to easily/quickly work around it, but it DOES work. The issue however is that the dialog box is not very helpful in telling you what login information you have to use (that is which username and password combination), and so I would like to replace it with a form. I had been thinking that this wasn't possible but I wanted to ask in order to find out. Is it possible to set up an HTML form that sends the data to the server such that it accepts it in the same way that it would using this dialog box? Alternatively is it possible to set up a PHP script that would take normal form data and process it somehow passing it to the server such that it logs in? Edit: After being told that this is basic authentication I went around and have managed to find a way that works and keeps the user persistently logged in. However, this does not work in internet explorer. The solution was simply to redirect the user to: http://username:[email protected]/vm.boatclub/password/index.php But Internet Explorer removed it due to phishing uses about 3 years ago. Is there a way to use javascript to get the browser to access the site in this way? Or will I have to simply change my UI?

• Umlaute from JSP-page are misinterpreted

  - by Karin

  I'm getting Input from a JSP page, that can contain Umlaute. (e.g. Ä,Ö,Ü,ä,ö,ü,ß). Whenever an Umlaut is entered in the Input field an incorrect value gets passed on. e.g. If an "ä" (UTF-8:U+00E4) gets entered in the input field, the String that is extracted from the argument is "ä" (UTF-8: U+00C3 and U+00A4) It seems to me as if the UTF-8 hex encoding (which is c3 a4 for an "ä") gets used for the conversion. How can I retrieved the correct value? Here are snippets from the current implementation The JSP-page passes the input value "pk" on to the processing logic: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> ... <input type="text" name="<%=pk.toString()%>" value="<%=value%>" size="70"/> <button type="submit" title="Edit" value='Save' onclick="action.value='doSave';pk.value='<%=pk.toString()%>'"><img src="icons/run.png"/>Save</button> The value gets retrieved from args and converted to a string: UUID pk = UUID.fromString(args.get("pk")); //$NON-NLS-1$ String value = args.get(pk.toString()); Note: Umlaute that are saved in the Database get displayed correctly on the page.

• .net real time stream processing - needed huge and fast RAM buffer

  - by mack369

  The application I'm developing communicates with an digital audio device, which is capable of sending 24 different voice streams at the same time. The device is connected via USB, using FTDI device (serial port emulator) and D2XX Drivers (basic COM driver is to slow to handle transfer of 4.5Mbit). Basically the application consist of 3 threads: Main thread - GUI, control, ect. Bus reader - in this thread data is continuously read from the device and saved to a file buffer (there is no logic in this thread) Data interpreter - this thread reads the data from file buffer, converts to samples, does simple sample processing and saves the samples to separate wav files. The reason why I used file buffer is that I wanted to be sure that I won't loose any samples. The application doesn't use recording all the time, so I've chosen this solution because it was safe. The application works fine, except that buffered wave file generator is pretty slow. For 24 parallel records of 1 minute, it takes about 4 minutes to complete the recording. I'm pretty sure that eliminating the use of hard drive in this process will increase the speed much. The second problem is that the file buffer is really heavy for long records and I can't clean this up until the end of data processing (it would slow down the process even more). For RAM buffer I need at lest 1GB to make it work properly. What is the best way to allocate such a big amount of memory in .NET? I'm going to use this memory in 2 threads so a fast synchronization mechanism needed. I'm thinking about a cycle buffer: one big array, the Bus Reader saves the data, the Data Interpreter reads it. What do you think about it? [edit] Now for buffering I'm using classes BinaryReader and BinaryWriter based on a file.

• C# vs C - Big performance difference

  - by John

  I'm finding massive performance differences between similar code in C anc C#. The C code is: #include <stdio.h> #include <time.h> #include <math.h> main() { int i; double root; clock_t start = clock(); for (i = 0 ; i <= 100000000; i++){ root = sqrt(i); } printf("Time elapsed: %f\n", ((double)clock() - start) / CLOCKS_PER_SEC); } And the C# (console app) is: using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { DateTime startTime = DateTime.Now; double root; for (int i = 0; i <= 100000000; i++) { root = Math.Sqrt(i); } TimeSpan runTime = DateTime.Now - startTime; Console.WriteLine("Time elapsed: " + Convert.ToString(runTime.TotalMilliseconds/1000)); } } } With the above code, the C# completes in 0.328125 seconds (release version) and the C takes 11.14 seconds to run. The c is being compiled to a windows executable using mingw. I've always been under the assumption that C/C++ were faster or at least comparable to C#.net. What exactly is causing the C to run over 30 times slower? EDIT: It does appear that the C# optimizer was removing the root as it wasn't being used. I changed the root assignment to root += and printed out the total at the end. I've also compiled the C using cl.exe with the /O2 flag set for max speed. The results are now: 3.75 seconds for the C 2.61 seconds for the C# The C is still taking longer, but this is acceptable

• Cocoa UI Elements Not Updating

  - by spamguy

  I have a few Cocoa UI elements with outlet connexions to an object instantiated within an NSView object, which is in turn put there by an NSViewController. These elements, a definite progress bar and a text label, are not updating: the progress bar is dead and empty despite having its value change constantly, the text label does not unhide through [textLabel setHidden:NO], the text label does not change its string. What I know: There's no difference between binding values and setting them in code. Nothing changes either way. I've checked outlet connections. They're all there. I've tried [X displayIfNeeded], where X has been the UI objects themselves, the containing NSView, and the main window. No difference. [progressBar setUsesThreadedAnimation:YES] makes no difference. Interestingly, if I look at progressBar mid-program, _threadedAnimation is still NO. The object holding all these outlets and performing an import operation is in an NSOperationQueue owned by the NSViewController object. Thanks! EDIT: As suggested, I called [self performSelectorOnMainThread:@selector(updateProgress:) withObject:[NSNumber numberWithInt:myObject] waitUntilDone:NO]. (I've also tried waitUntilDone:YES.) It's still not updating. The debugger clearly shows updateProgress: taking place in the main thread, so I don't know what's missing.

• Need to call original function from detoured function

  - by peachykeen

  I'm using Detours to hook into an executable's message function, but I need to run my own code and then call the original code. From what I've seen in the Detours docs, it definitely sounds like that should happen automatically. The original function prints a message to the screen, but as soon as I attach a detour it starts running my code and stops printing. The original function code is roughly: void CGuiObject::AppendMsgToBuffer(classA, unsigned long, unsigned long, int, classB); My function is: void CGuiObject_AppendMsgToBuffer( [same params, with names] ); I know the memory position the original function resides in, so using: DWORD OrigPos = 0x0040592C; DetourAttach( (void*)OrigPos, CGuiObject_AppendMsgToBuffer); gets me into the function. This code works almost perfectly: my function is called with the proper parameters. However, execution leaves my function and the original code is not called. I've tried jmping back in, but that crashes the program (I'm assuming the code Detours moved to fit the hook is responsible for the crash). Edit: I've managed to fix the first issue, with no returning to program execution. By calling the OrigPos value as a function, I'm able to go to the "trampoline" function and from there on to the original code. However, somewhere along the lines the registers are changing and that is causing the program to crash with a segfault as soon as I get back into the original code.

• How to convert struct to char array in C

  - by falcojr

  I'm trying to convert a struct to a char array to send over the network. However, I get some weird output from the char array when I do. #include <stdio.h> struct x { int x; } __attribute__((packed)); int main() { struct x a; a.x=127; char *b = (char *)&a; int i; for (i=0; i<4; i++) printf("%02x ", b[i]); printf("\n"); for (i=0; i<4; i++) printf("%d ", b[i]); printf("\n"); return 0; } Here is the output for various values of a.x (on an X86 using gcc): 127: 7f 00 00 00 127 0 0 0 128: ffffff80 00 00 00 -128 0 0 0 255: ffffffff 00 00 00 -1 0 0 0 256: 00 01 00 00 0 1 0 0 I understand the values for 127 and 256, but why do the numbers change when going to 128? Why wouldn't it just be: 80 00 00 00 128 0 0 0 Am I forgetting to do something in the conversion process or am I forgetting something about integer representation? *Note: This is just a small test program. In a real program I have more in the struct, better variable names, and I convert to little-endian. *Edit: formatting

• How to get smartcard reader name in Windows 7 using C# or C/C++?

  - by AndrejaKo

  Hi! I'm trying to make a C# program which will use a C .dll (unfortunately, the .dll doesn't have good documentation) to access a smart card. One of the functions of the .dll uses name of the reader as argument. My problem is that I don't know how to get the name. After looking for answers I found something similar to what I need in an example here: http://msdn.microsoft.com/en-us/library/aa379803%28VS.85%29.aspx I'm looking for a way to get szReader value as described in the aforementioned example using C#. Can anyone help me or at least point me in the right direction? EDIT: Looks like nobody knows the answer so I'll expand the question: How do I get smartcard reader name using C/C++ and Windows API? I've read through MSDN site for smartcard API, but I couldn't find the function which will list readers. My idea is now to make a C/C++ .dll which will get in-between the smartcard .dll and C# program. It will produce list of readers, let user chose one and call the smartcard .dll using chosen name as argument.

• How to Get Specific Button pressed in a repeater when using ModalPopupExtender

  - by MemphisDeveloper

  I have buttons contained within a repeater. A ModalPopupExtender is used to confirm event for each button. I create standard panels outside of the repeater and I attach each button in the repeater to these panels from inside the repeater. The problem is once the button is pressed in the popup I can't figure out how to determine which row of the repeater to edit as I can't figure out how to identify which button was pressed. Panel: <asp:Panel ID="pnlRemoveAlert" runat="server" > <h1 align="center">Remove Phone</h1> <asp:Button ID="butRemove" runat="server" OnCommand="Handle_Click" CommandName="Remove" Text="Continue"/> <asp:Button ID="butRemoveCancel" runat="server" Text="Cancel"/> </asp:Panel> Repeater: <asp:Repeater ID="repPhoneNumbers" runat="server" OnItemDataBound="setButtonModals"> <ItemTemplate> ... <asp:Button ID="btnStatus" runat="server"/> <asp:Button ID="dummybutton" runat="Server" Visible="false" /> <ajaxToolkit:ModalPopupExtender ID="mpeEnable" runat="server" TargetControlID = "btnStatus CancelControlID="butEnableCancel" PopupControlID="pnlEnableAlert"/> ...

• DataGrid: dynamic DataTemplate for dynamic DataGridTemplateColumn

  - by Lukas Cenovsky

  I want to show data in a datagrid where the data is a collection of public class Thing { public string Foo { get; set; } public string Bar { get; set; } public List<Candidate> Candidates { get; set; } } public class Candidate { public string FirstName { get; set; } public string LastName { get; set; } ... } where the number of candidates in Candidates list varies at runtime. Desired grid layout looks like this Foo | Bar | Candidate 1 | Candidate 2 | ... | Candidate N I'd like to have a DataTemplate for each Candidate as I plan changing it during runtime - user can choose what info about candidate is displayed in different columns (candidate is just an example, I have different object). That means I also want to change the column templates in runtime although this can be achieved by one big template and collapsing its parts. I know about two ways how to achieve my goals (both quite similar): Use AutoGeneratingColumn event and create Candidates columns Add Columns manually In both cases I need to load the DataTemplate from string with XamlReader. Before that I have to edit the string to change the binding to wanted Candidate. Is there a better way how to create a DataGrid with unknown number of DataGridTemplateColumn? Note: This question is based on dynamic datatemplate with valueconverter

• ASP Menu driving me insane

  - by simplesimon

  Hi there, I am trying to create a menu using ASP (I have never used ASP before, im a PHP man) using values stored in a database. basically the html layout i want is as such: <ul> <li> <ul class="sub-menu"> <li class="sub-menu-li">Test</li> </ul> </li> </ul> I need to loop around the root menu items rs("AD_Level") which is equal to 0 for root objects, then inside that loop, lop around anything that has the same parent id eg if the current record is AD_Level =0 and AD_Parent=5 then loop around all items with AD_Parent 5 and AD_Level != 0 and insert the values into html and so on and so forth. Please help! I am struggling with a new language and cannot see a way to do this without losing sanity Edit (Extracted from Comment by OP) while not rsAdmin.eof sPar = rsAdmin("ad_parent" if rsAdmin("AD_Level")=0 then while not rsAdmin2.eof if rsAdmin2("AD_Level")<>0 and rsAdmin2("ad_parent")=sPar and rsAdmin2("AD_Sec_Level")=>2 then response.write rsAdmin("AD_Menu") end if rsAdmin2.movenext wend end if '' # if not rsAdmin.eof then sPar=rsAdmin("AD_parent") rsAdmin.movenext wend that is my code

• Browser-based application or stand-alone GUI app?

  - by crystalattice

  I'm sure this has been asked before, but I can't find it. What are the benefits/limitations of using a browser-based interface for a stand-alone application vs. using a normal GUI framework? I'm working on a Python program currently implement with wxPython for the GUI. The application is simply user-entry forms and dialogs. I am considering moving to PyQt because of the widgets it has (for future expansion), then I realized I could probably just use a browser to do much of the same stuff. The application currently doesn't require Internet access, though it's a possibility in the future. I was thinking of using Karrigell for the web framework if I go browser-based. Edit For clarification, as of right now the application would be browser-based, not web-based. All the information would be stored locally on the client computer; no server calls would need to be made and no Internet access required (it may come later though). It would simply be a browser GUI instead of a wxPython/PyQt GUI. Hope that makes sense.

• What is the best way to call a method right AFTER a form loads?

  - by Jordan S

  I have a C# windows forms application. The way I currently have it set up, when Form1_Load() runs it checks for recovered unsaved data and if it finds some it prompts the user if they want to open that data. When the program runs it works alright but the message box is shown right away and the main program form (Form1) does not show until after the user clicks yes or no. I would like the Form1 to pop up first and then the message box prompt. Now to get around this problem before I have created a timer in my Form, started the timer in the Form1_Load() method, and then performed the check and user prompt in the first Timer Tick Event. This technique solves the problem but is seems like there might be a better way. Do you guys have any better ideas? Edit: I think I have also used a background worker to do something similar. It just seems kinda goofy to go through all the trouble of invoking the method to back to the form thread and all that crap just to have it delayed a couple milliseconds!

• ListView Final Column Autosize creates scrollbar

  - by Courtney de Lautour

  Hi There, I am implementing a custom control which derives from ListView. I would like for the final column to fill the remaining space (Quite a common task), I have gone about this via overriding the OnResize method: protected override void OnResize(EventArgs e) { base.OnResize(e); if (Columns.Count == 0) return; Columns[Columns.Count - 1].Width = -2; // -2 = Fill remaining space } or via another method: protected override void OnResize(EventArgs e) { base.OnResize(e); if (!_autoFillLastColumn) return; if (Columns.Count == 0) return; int TotalWidth = 0; int i = 0; for (; i < Columns.Count - 1; i++) { TotalWidth += Columns[i].Width; } Columns[i].Width = this.DisplayRectangle.Width - TotalWidth; } Edit: This works fine until I dock the ListView into a parent container and resize via that control. Every second time the control size shrinks (IE, drag the the border one pixel), I get a scroll bar on the bottom which can't move at all (not even one pixel). The result of which is when I drag the size of the parent I am left with a flickering scroll bar in the ListView, and a 50% chance it will be there when the dragging stops.

• Listing serial (COM) ports on Windows?

  - by Eli Bendersky

  Hello, I'm looking for a robust way to list the available serial (COM) ports on a Windows machine. There's this post about using WMI, but I would like something less .NET specific - I want to get the list of ports in a Python or a C++ program, without .NET. I currently know of two other approaches: Reading the information in the HARDWARE\\DEVICEMAP\\SERIALCOMM registry key. This looks like a great option, but is it robust? I can't find a guarantee online or in MSDN that this registry cell indeed always holds the full list of available ports. Tryint to call CreateFile on COMN with N a number from 1 to something. This isn't good enough, because some COM ports aren't named COMN. For example, some virtual COM ports created are named CSNA0, CSNB0, and so on, so I wouldn't rely on this method. Any other methods/ideas/experience to share? Edit: by the way, here's a simple Python implementation of reading the port names from registry: import _winreg as winreg import itertools def enumerate_serial_ports(): """ Uses the Win32 registry to return a iterator of serial (COM) ports existing on this computer. """ path = 'HARDWARE\\DEVICEMAP\\SERIALCOMM' try: key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, path) except WindowsError: raise IterationError for i in itertools.count(): try: val = winreg.EnumValue(key, i) yield (str(val[1]), str(val[0])) except EnvironmentError: break

• Windows theme affecting ListView header

  - by LihO

  I've created new Windows Forms Application (C#) with one simple form containing ListView. Then I changed the View Property to Details and increased the size of the font used in this ListView and here's the result: This is how it looks on Windows XP with Windows Classic theme: and here's the result with Windows XP theme: Creating the same Windows Forms Application in Visual C++ instead of C# yields same result. EDIT : Thanks to Kamil Lach, we already know that Visual Styles is what makes the appearance of ListView change. This can be avoided either by removing Application.EnableVisualStyles() call or by changing the Application.VisualStyleState. Both of these solutions yield the following result: This looks fine, but this change affects the appearance of other controls which is not good. I'd like my ListView to be the only control that is not affected by Visual Styles. I've also found similar questions that try to deal with it: Can you turn off visual styles/theming for just a single windows control? How do I disable visual styles for just one control, and not its children? Unfortunately, none of mentioned solutions works. Any C# solution that would make the ListView header have the correct height would be appreciated.

• Help understanding .NET delegates, events, and eventhandlers

  - by Seth Spearman

  Hello, In the last couple of days I asked a couple of questions about delegates HERE and HERE. I confess...I don't really understand delegates. And I REALLY REALLY REALLY want to understand and master them. (I can define them--type safe function pointers--but since I have little experience with C type languages it is not really helpful.) Can anyone recommend some online resource(s) that will explain delegates in a way that presumes nothing? This is one of those moments where I suspect that VB actually handicaps me because it does some wiring for me behind the scenes. The ideal resource would just explain what delegates are, without reference to anything else like (events and eventhandlers), would show me how all everything is wired up, explain (as I just learned) that delegates are types and what makes them unique as a type (perhaps using a little ildasm magic)). That foundation would then expand to explain how delegates are related to events and eventhandlers which would need a pretty good explanation in there own right. Finally this resource could tie it all together using real examples and explain what wiring DOES happen automatically by the compiler, how to use them, etc. And, oh yeah, when you should and should not use delegates, in other words, downsides and alternatives to using delegates. What say ye? Can any of you point me to resource(s) that can help me begin my journey to mastery? EDIT One last thing. The ideal resource will explain how you can and cannot use delegates in an interface declaration. That is something that really tripped me up. Thanks for your help. Seth

• Does Java 6 open a default port for JMX remote connections?

  - by Bob Cross

  My specific question has to do with JMX as used in JDK 1.6: if I am running a Java process using JRE 1.6 with com.sun.management.jmxremote in the command line, does Java pick a default port for remote JMX connections? Backstory: I am currently trying to develop a procedure to give to a customer that will enable them to connect to one of our processes via JMX from a remote machine. The goal is to facillitate their remote debugging of a situation occurring on a real-time display console. Because of their service level agreement, they are strongly motivated to capture as much data as possible and, if the situation looks too complicated to fix quickly, to restart the display console and allow it to reconnect to the server-side. I am aware the I could run jconsole on JDK 1.6 processes and jvisualvm on post-JDK 1.6.7 processes given physical access to the console. However, because of the operational requirements and people problems involved, we are strongly motivated to grab the data that we need remotely and get them up and running again. EDIT: I am aware of the command line port property com.sun.management.jmxremote.port=portNum The question that I am trying to answer is, if you do not set that property at the command line, does Java pick another port for remote monitoring? If so, how could you determine what it might be?

• Looking for good PHP editor or IDE with 'IntelliSense'

  - by Andrew

  Hello, I'm looking for suitable PHP Editor or IDE with syntax auto-completion. I've tried trial versions of programs like Zend Studio, PHPDesigner, NetBeans PHP, NuSphere PhpED, and similar -- but none of them fully satisfied me. I quite liked hint window with detailed info about what function does and what it returns. Also I liked the way NetBeans auto-complete code (for example inserts all required parameters in function declaration as "dummy fields" and then you can jump between them using TAB in order to edit them). On the other hand, environment of NetBeans doesn't belong to the nicest. In this regard I prefer PHPDesigner with its sleek and light interface. At this moment I don't use any of the debugging options, since I don't know yet how to use profiller, breakpoints, watches and what not, so at this point my only concern is good autocompletion. For this purpose NetBean would be great choice, but with future in mind I am not sure debugging will be good in NetBeans, especially as I would prefer to use remote Linux server for this. So in short, I'm looking for editor that: Have similar code auto-completion (IntelliSense) like NetBeans Allow you to debug code using remote server (or sets up own debugging server like PHPDesigner does) without need to run Apache and similar on local computer Is preferably easy to use / intuitive interface Any ideas?

• How do I get Ctrl-Backspace to delete a word in vim within gnome-terminal?

  - by Michael Gundlach

  I'd like Ctrl-Backspace to delete the current word in vim insert mode. From within xterm I can pull this off via :inoremap <C-H> <C-W> but in gnome-terminal I cannot figure out a way to make it happen. When in vim insert mode, if I type control-v and then press backspace, I get ^H in xterm, and ^? in gnome-terminal. Unfortunately, :inoremap <C-?> <C-W> doesn't do the trick in gnome-terminal; control-backspace just erases a single character no matter what. Regarding ASCII codes: Gnome-terminal lets you change the backspace character under Edit - Profile Preferences - Compatibility. Unfortunately, no option works, as far as I can tell: whatever character I apply to Backspace via the settings, if I try mapping the character itself, like :inoremap <C-H> <C-W> then regular backspace and control-backspace both erase an entire word; and if I try mapping control plus that character, like :inoremap <C-^H> <C-W> then regular backspace and control-backspace just erase a single character.

• Jquery .val() for input only works once.

  - by Bolt_Head

  I'm trying to create a chat box for my game. The user type's their chat into the input:text feild and by ither pressing Enter or clicking the button submits the chat text. This all works, however for some reason after the first time a user submits a chat message it fails to get the text from the input field. Here is my code. $(document).ready(function() { $("#chatEnter").live('click',function(){ var chat = $('#chatText').val(); sendChat(chat); }); }); $(document).ready(function() { $("#chatText").keypress(function(e){ if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { var chat = $('#chatText').val(); sendChat(chat); return false; } else return true; }); }); function sendChat(chat) { alert(chat); //temp test alert $.getJSON("includes/boardUpdate.php",{chat: chat, bid: bid}); $('#chatText').val(""); } It doesn't matter if i first submit a text by clicking the button or pressing enter, all future attempts submit blank entrys until I refresh the page. Edit: I've tried it with and without the line to clear the text box, same results both ways. Your help is appreciated.

• Removing NSLog breaks compiler

  Okay, so this is weird I have this code - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { switch (indexPath.row) { case 1: NSLog(@"Platform Cell Selected"); AddGamePlatformSelectionViewController *platformVC = [[AddGamePlatformSelectionViewController alloc] initWithNibName:@"AddGamePlatformSelectionViewController" bundle:nil]; platformVC.context = context; platformVC.game = newGame; [self.navigationController pushViewController:platformVC animated:YES]; [platformVC release]; break; default: break; } } Which works fine.

• Remove "Flash" between pages while using Internet Explorer modal boxes

  - by AaronS

  I have an internal web application, that is IE specific, and uses a lot of IE specific modal boxes: (window.showModalDialog). I recently received a request to remove the "flash" when navigating between pages of the site. To accomplish this, I just added a meta transition tag to my master page: <meta http-equiv="Page-Enter" content="blendTrans(duration=0.0)" /> This works perfectly except for the modal boxes. When you launch a modal box, and then move it around, the web page behind it keeps a trail of the modal box instead of re-drawing the web page content. This prevents the user from moving the modal box to read anything that was behind it. Is there a way to prevent the "flash" between pages in an IE specific site and have the site still work with modal boxes? Please note, this is a large and complex site, so re-architecting it to not use modal boxes isn't an option.

• How do I find Microsoft APIs?

  - by Stephen

  I'm a java programmer, and if I see something that: I don't know about or just want to find a method description without opening an ide or am on support I type java [classname] into google, and there it is. If I try this crazy stunt for C# I'll come up with a whole heap of tutorials (how do I use it etc). If I manage to get to MSDN, I have to wade through a page describing every .net technology to see how their syntax references the same object, and then I have to find the appropriate page from there ([class name] Constructor) for example. This is even more pronounced, because I don't have Visual Studio, so I've got nothing to make it easier. There must be something I'm missing or don't know... how does this situation work for Microsoft developers? how can I make my life easier/searches better? are there techniques that work no matter what computer I'm on (e.g. require no computer setup/downloads) Notes It could be thought that java is just "java", but it's just that the java apis are only referenced/defined in the core language. For all the other languages on the JVM, it's assumed that you will just learn the correct syntax to use the java apis. I presume that .Net only lists a whole heap of languages as the api classes are actually different and have different interfaces capabilities (or some approximation of this presumption). Edit While searching msdn works... in the java space I can type 'java [anyclass]' and it will generally be found... whether it's a java core api or a third party library
