• Launching default browser with html from file, then jump to specific anchor

  - by Holman716

  I need to open an html file from the program root directory and have it jump to a specified anchor. I can open the file perfectly fine with a simple System.Diagnostics.Process.Start("site.html") but as soon as I try to add the anchor to the end it ceases to be able to find the file. I was able to put the anchor in there and still have it launch with string Anchor Anchor = "file:///" + Environment.CurrentDirectory.ToString().Replace("\", "/") + "/site.html#Anchor"; System.Diagnostics.Process.Start(Anchor); However as soon as the browser launches it drops the anchor. Any suggestions?

• Is Learning the win32 API Worthwhile?

  - by kronoz

  I was certain that somebody would have specifically asked this question, but from what I can see no-one has (there's been a question about learning win32 but that doesn't cover whether it's worthwhile doing so). I am very interested in gaining a deeper understanding of all the systems I use (I mostly program in C#, at least professionally), so I wondered, very simply - is learning win32 worthwhile, or is it overkill? Am I wasting my time? Is the knowledge I'd gain worth the effort? Similar / related questions on StackOverflow: Does it still make sense to learn low level WinAPI programming? How relevant is Win32 programming to modern professionals?

• How to have a run in an Service?

  - by user1497664

  I have implemented an service that runs in a seperate process. This service contains a separate thread where i have a socket connection. This thread has a run() where it is continuously sending data to the port. My problem is after triggering the run() in the thread i don't get any contact with it anymore, i can see in the program that have open the socket that it consciously sends the data but the idea was that i while it is running i could change data that it sends for an example time. here is my run in the external thread: public void run() { if(run) { // Team and player names message is sent when entering in a game setBaseMessage(); SendMessageToCOMPort(base_message + CalculateCRC(base_message)); sleep(); // waits for 100 ms } } Anyone have any idea what might be wrong ?

• ExtJS (4.0) dynamic / lazy loading

  - by Paul

  Given a border layout with a west (navigation) and a center region. Let say I click on topic A in the west region, I want to replace (replace as in 'delete last topic') the center region with 'extjs' program code named topic_a.js I succeed in loading with this code: dynamicPanel = new Ext.Component({ loader: { url: '/www/file.htm', renderer: 'html', autoLoad: true, scripts: true } }); var oMainContainer = Ext.getCmp('maincontainer'); oMainContainer.show(); oMainContainer.add(dynamicPanel); But calling this the second time 'adds' things up in the center region and of course fails short in 'deleting', what would be a good approach?

• 3D Mesh Joining

  - by morlst

  I have 2 (or more) intersecting meshes, which require joining into 1 mesh object. I want to have some control over the resulting seam vertex insertion, so looking to write myself rather than use a library. Has anyone come across some open source code to base the algorithm on / ideas on the process? Initial impressions are: 1. Present in every 3D modelling program - mostly reinventing existing process (hence search for examples) 2. Potential for fiddly-ness around the polygon face direction and just touching conditions. (see above point)

• Crash when checking BOF property of pessimistic locked ADO recordset

  - by Patrick

  Bit of an odd one for you: I've got two connections to a database, on one I've opened a _RecordsetPtr with a pessimistic lock. I can no longer send an UPDATE command on the other connection. I can send a SELECT command on the second connection and data is returned. If I use a read only lock then there are no problems however when I use a pessimistic lock on the second connection as well I can check the State == adStateOpen but the program hangs when I test the BOF property! If I don't test the BOF property and try to call moveNext on the second connection the software hangs If I do neither of these I am able to access the data via the second connection but trying to access the data from the first connection causes the software to hang. Any one seen anything similar as I'm a bit stuck? EDIT : it wasn't hanging, someone had put a 30 minute timeout on the connection and I wasn't waiting that long while testing...

• FTP .NET Sockets

  - by Jojo

  Hi Everyone, I have an FTP auto downloader program. It downloads new files from a given FTP folder. The application was successful for some FTP folders that i have tested. These folders contain 30 - 50 files. However, when i tried an FTP folder with 150 and 18000 files, i receive this error message: An established connection was aborted by the software in your host machine. My first assumptions will be because of firewalls or anti virus. I don't have administrative access to this computer so I would like to ask if there are other reasons for this before i raise this to our systems dept? Need anyone's help asap. Thanks :)

• SQL Server 2008 error message from stored procedure

  - by George2

  Hello everyone, I am using SQL Server 2008 Enterprise. When we met with such error message from stored procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim. Rerun the transaction. I am wondering whether such messages are stored in log files? I searched log folder of my SQL Server 2008 installation root (in my environment, it is C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Log), but can not find such files. thanks in advance, George

• Applet in client-server infrastructure

  - by Andrey

  Hello! I have a general question concerning client-server design. We have a Java server with Spring, a GWT client program and some HTTP-servlets for our site. At the moment we also want to develop an applet which would communicate with that server in such a way GWT-client and site requests do. Is it a good idea to communicate with the server from applet by RMI? I.e. to create some Remote services, register them with Spring and call them from applet? Thanks in advance!

• Passing a multi-line string as an argument to a script in Windows

  - by Zack Mulgrew

  I have a simple python script like so: import sys lines = sys.argv[1] for line in lines.splitlines(): print line I want to call it from the command line (or a .bat file) but the first argument may (and probably will) be a string with multiple lines in it. How does one do this? Of course, this works: import sys lines = """This is a string It has multiple lines there are three total""" for line in lines.splitlines(): print line But I need to be able to process an argument line-by-line. EDIT: This is probably more of a Windows command-line problem than a Python problem. EDIT 2: Thanks for all of the good suggestions. It doesn't look like it's possible. I can't use another shell because I'm actually trying to invoke the script from another program which seems to use the Windows command-line behind the scenes.

• How do you pass an enum by reference?

  - by Darkenor

  I have an enum with four keys I'm taking as input for an interface program and I'd like to pass the enum by value to the interface function, which has become quite long. The enum is like this: enum MYKEYS { W, S, O, L }; There's also a boolean array that I have to pass by reference, which is also a little tricky. bool key[4] = { false, false, false, false }; Does anyone know the proper syntax to pass both of these as reference in a function, similar to: function(int & anintreference);

• What is a Custom Class?

  - by John Saunders

  Many questions here on SO ask about custom classes. I, on the other hand, have no idea what they're talking about. "Custom class" seems to mean the same thing I mean when I say "class". What did I miss, back in the '80s, that keeps me from understanding? I know that it's possible to purchase a packaged system - for Accounting, ERP, or something like that. You can then customize it, or add "custom code" to make the package do things that are specific to your business. But that doesn't describe the process used in writing a .NET program. In this case, the entire purpose of the .NET Framework is to allow us to write our own code. There is nothing useful out of the box.

• Operations on 64bit words in 32bit system

  - by Vilo

  I'm new here same as I'm new with assembly. I hope that you can help me to start. I'm using 32bit (i686) Ubuntu to make programs in assembly, using gcc compiler. I know that general-purpose-registers are 32bit (4 bytes) max, but what when I have to operate on 64 bit numbers? Intel's instruction says that higher bits are stored in %edx and lower in %eax Great... So how can I do something with this 2-registers number? I have to convert 64bit dec to bin, then save it to memory and show on the screen. How to make the 64bit quadword at start of the program in .data section?

• How do I make a project built into a downloadable Cd?

  - by Dcurvez

  hi all I just got finished making my first project in visual studio 2008. what I want to do is put it on a CD and let another person run it. I went to the clean and build and publish and all went well. When I took it to my friends house to put it on her computer..i never got a "download" and "install" screen. We were able to see it and use it on her computer (which is good cuz she doesnt have Visual on her machine) but I wanted her to be able to use it without keeping the CD in the drive. Is there some setup or something I have to do to make my program download and install? The whole shibang was all done with starting a new windows application..and then just adding windows forms to the original. Thanks :)

• How to maintain 2 lists of object

  - by michael

  Hi, My c++ program needs to maintain 2 list of objects. list inuse; list free; So objects A can even in 'inuse' list or in 'free' list, but not both. http://www.cplusplus.com/reference/stl/list/ I am think of using 'list' as the data structure for my lists. My questions are 1. why i can't randomly access an elmenet in the list, I look at the above api, I don't see a way to get inuse[2]; 2. How can I remove an element in the list? There is an erase(), but how can I use it to remove element #2? And after I remove element 2? will STL list fill the erased spot automatically? e.g. #3 will become #2, #4 will become #3 and so on? Thank you.

• A strange issue... No code changes getting reflected.

  - by sachin

  I am using netbeans to develop an applet, i have a piece of code which looked like this: ipAddresss = DEFAULT_IP; System.out.println("portlet.services.hostname:" + ipAddresss); Now I changed it to something like this: ipAddresss = DEFAULT_IP; System.out.println("portlet.services.hostname using default IP Address:" + ipAddresss); But no matter what I do, it sill keep on printing: portlet.services.hostname:null I have tried deleting all .netbeans folder from documents and settings, tried creating new project, but now i am completely baffled by this issue... So, the problem is, no matter what I do, no change is getting reflected when I run the program. Can there be a java applet cache, netbeans cache, i am not sure why...

• Staticly linked libraries not running code inside to setup static variables.

  - by MJD

  In a c++ project I am working on, I have a simple c++ file that needs to run some code at the beginning of the progam execution. This file is linked into a static library, which is then linked into the main program. I have similar code in other files running fine, that looks something like: bool ____nonexistant_value = executeAction(); However, it does not work inside this file unless I make use of a function implemented in this file. It does work if the library is compilied as a shared library. I'd prefer to link this statically as the library is only a convience as the file is in a different directory.

• SetWindowLongPtr with DialogBoxParam?

  - by templatetypedef

  Hey all- A while back I was writing a C++ program with the Win32 API that would display a dialog box and then listen to the messages it generated. At one point, I was interested in associating a piece of data with the dialog window. Were I manually creating the window and attaching a window proc, I'd just use SetWindowLongPtr to set the GWLP_USERDATA field to a pointer to the data to associate. However, in this case I was creating and displaying the window with DialogBoxParam, and it wasn't clear whether this function was associating that data with its own internal state. Since the MSDN didn't have a description of what would happen in this case, I ended up using some other approach to solve the problem. My question is this - is it safe to use SetWindowLongPtr to overwrite the GWLP_USERDATA value in a window created by DialogBoxParam? Thanks!

• Sending a Java object from my Android phone to my Computer

  - by TehGoose

  Hi, I was wondering what the simplest program for sending an object from my Andriod phone to my computer wirelessly (via LAN) would be. I have created Java RMI programs with a server and multiple clients, so I have a grasp of the concept. However with android I'm just not sure where to start. What I am aiming to do is send some sort of information (could simply be text) to my computer and my computer will do an action. I have the GUI interface's and the actions to be carried out all worked out, just the sending of some sort of information is getting me. Could anyone help me out?

• Splitting up input using regular expressions in Java

  - by Joe24

  I am making a program that lets a user input a chemical for example C9H11N02. When they enter that I want to split it up into pieces so I can have it like C9, H11, N, 02. When I have it like this I want to make changes to it so I can make it C10H12N203 and then put it back together. This is what I have done so far. using the regular expression I have used I can extract the integer value, but how would I go about get C10, H11 etc..? System.out.println("Enter Data"); Scanner k = new Scanner( System.in ); String input = k.nextLine(); String reg = "\\s\\s\\s"; String [] data; data = input.split( reg ); int m = Integer.parseInt( data[0] ); int n = Integer.parseInt( data[1] );

Am I missing something?

• Swing: Programmatically select a text

  - by HH

  Hey everyone, I have a very simple Swing GUI with just a JTetxtArea. I am trying to programmatically select a part of text using: textArea.select(startSelection,endSelection); This work. However as soon as I add some other components to the GUI I do not see selection anymore frame.getContentPane().add(button); frame.getContentPane().add(textArea); textArea.select(startSelection,endSelection); I suspect that during layouting the gui, some event causes the text to be deselected. Am I right? And could anybody suggest a solution? My goal is to have a program which displays a text, and allows the user to input start and end selection position, and a selection appears between these two position. Thank you.

• vb express / visual studio - is it possible to run / debug one form only in a multi form application

  - by Luay

  hi, I have a vb application consisting of several winForms and code files. Is it possible to run / debug only one form without having to run the whole application? To be more specific, one of the forms in my application is the settings form where the user sets his/her desired options. These options are read/written to an xml file. Is it possible to debug just this one form (and not the whole program) to see if the reading/writing went well, if everything displayed correctly... ? If I am thinking the wrong way about this, could you point me in the right direction? By the way, I am using visual basic express / visual studio.
