• Starting x11vnc remotely when X server is already running

  - by Madiyaan Damha

  I have a ubuntu linux machine that I have already logged into and X server is running (it is pass the login manager like gdm). I can access this machine through ssh. My goal is to start x11vnc on this machine and attach it to the X server that is already running. When I ssh into the machine and start x11vnc, it says: X11 was unable to open the X DISPLAY ":0", it cannot continue. How can I start x11vnc on the remote machine if I don't have physical access to it and Xserver has already started. The reason I want to do this is because the remote machine has several windows open that I want to work on. Thanks,

• Upload image with Photoshop scripting

  - by cosmorocket

  Is that possible to upload an image from Photoshop (for example, an open image exported to jpeg) to some web place - REST service, FTP etc by using scripting features of Photoshop? For example - I have an image open in Photoshop and then execute some special script that sends an exported version of it to some place over the web. I saw something like this but it uses an automatically generated batch file that executes ftp command on Windows. I would like to use something more beautiful if it's possible. Or may be there are some info to know how to make a simple plugin for just this task. Thanks.

• How to prevent multiple browser windows from sharing the same session in asp.net.

  - by Barry

  I have ASP.net application that is basically a data entry screen for a physical inspection process. The users want to be able to have multiple browser windows open and enter data from multiple inspections concurrently. At first I was using cookie based sessions, and obviously this blew up. I switched to using cookie-less sessions, which stores the session in the URL and in testing this seemed to resolve the problem. Each browser window/tab had a different session ID, and data entered in one did not clobber data entered in the other. However my users are more efficient at breaking things than I expected and it seems that they're still managing to get the same session between browsers sometimes. I think that they're copying/pasting the address from one tab to the other in order to open the application, but I haven't been able to verify this yet (they're at another location so I can't easily ask them). Other than telling them don't copy and paste, or convince them to only enter one at a time, how can I prevent this situation from occurring?

• What are the requirements for HTA files?

  - by SLC

  They seem to open in an internet explorer type window, does anyone know: How long have HTA files been around? Have they been around since Windows 98? Do they rely on Internet Explorer being installed, and/or a certain version of it? If you choose another browser on the browser selection screen update for Windows 7, will HTA files still work? Do HTA files open on other browsers? Are HTA files windows-only? There is a huge lack of documentation on google about HTA files, so it's tricky to work out. I need to present the client with a list of minimum requirements to ensure our HTA content CD will work.

• Exception while opening file

  - by viswanathan

  Hi I have a VC++ application and in my application i have some basic file operations. Below is the defaulting code CStdioFile cFile; CFileException e; CString sReport; CString sHtmlfile = "testreport.html" OutputDebugString((sHtmlfile)); if (!cFile.Open(sHtmlfile,CFile::modeCreate | CFile::modeWrite, &e )) { } The problem is my application executes this piece of code every few minutes. and it works fine. After several runs of the code the cFile.Open() function fails. I tried to get the error message TCHAR szError[1024]; e.GetErrorMessage(szError,1024); OutputDebugString((szError)); The irony is the szError error message is "No error occured". This again works once i restart my application. Any idea why this occurs. Thanks in advance.

• Which is the best .NET image capture API for me to use?

  - by David

  I have been tasked with integrating image acquisition into a .NET application and I have been looking for an API to use for performing this function. I have come across several "standard" APIs, some have been in existence for a long time, some not so long. I have looked at references to ISIS, TWAIN, WIA, and SANE (said to be mostly *nix). They all appear to be Win32 libraries except for SANE, and I was wondering what the current recommendations are for talking to image acquisition devices (scanners)? Feel free to recommend something else if you feel it is better. I'm looking for open source options. Edit: I put open source, when what I actually meant was free. using WIA or TWAIN is fine since they are free even though they are proprietary interfaces.

• How can I redirect the output of Perl's system() to a filehandle?

  - by syker

  With the open command in Perl, you can use a filehandle. However I have trouble getting back the exit code with the open command in Perl. With the system command in Perl, I can get back the exit code of the program I'm running. However I want to just redirect the STDOUT to some filehandle (no stderr). My stdout is going to be a line-by-line output of key-value pairs that I want to insert into a mao in perl. That is why I want to redirect only my stdout from my Java program in perl. Is that possible? Note: If I get errors, the errors get printed to stderr. One possibility is to check if anything gets printed to stderr so that I can quite the Perl script.

• Dreamweaver - template not recognising child files until they are opened

  - by Chris

  Hi I've got a new section for a website which I have generated for a data source and it has markup for using a Dreamweaver template. When I add the new files and folders to the site , then update my template , it doesn't find the new files to update. If I open one of the new files , make a change in the template , then it recognises the new file is using the template. So it's almost like I have to touch all the files with Dreamweaver first. I've tried to open all the new files which need to use the template but then Dreamweaver CS4 crashes, I presume because of the number of files it's opening. Anyway, does anyone know if there is a way to make Dreamweaver recognise that a block of new files belong to the template , it doesn't seem to just work automatically Thanks Chris

• Opening a text file in browser - error on server

  - by Lehan Coetzee

  I'm trying to open a text file in my browser, when doing it from my local machine it works perfectly but when I upload my files to my web server the link to the text file no longer works and I get a broken link error from the browser. Here is my code for opening the txt file: <div style="width: 100%; background-color: #CCC;text-align: center;"> <a href="code.txt" onclick="window.open(this.href,this.target,'height=300, width=500');return false;">Code</a> </div>

• Is there a Windows API to modify file type associations for an extension?

  - by JohnFx

  I'm looking for a way to programatically tweak the particulars of a file association on a Windows system. For example, the "Application User to Perform this Action" setting for the "Open" action for a particular file type. Clearly I could do this by modifying the registry directly, but if there is an API I'd prefer to use that as it would likely be more resilient to changes in the OS handling of mapping extensions to applications. For my purposes I'm needing to write this in VBScript (.VBS) file because it is part of a package to be used with VMWare ThinApp that mandates it. However, I'll port/wrap/whatever I need to make this week, so I am open to any solution (including using the .NET framework)

• WPF Standard Commands - Where's Exit?

  - by Andrew Shepherd

  I'm creating a standard menu in my WPF application. I know that I can create custom commands, but I know there are also a bunch of standard commands to bind to. For example, to open a file I should bind to ApplicationCommands.Open, to close a file I should bind to ApplicationCommands.Close. There's also a large number of EditCommands, ComponentCommands or NavigationCommands. There doesn't seem to be an "Exit" command. I would have expected there to be ApplicationCommands.Exit. What should I bind to the "Exit" menu item? To create a custom command for something this generic just seems wrong.

• How do I view application directories and directories that begin with dot in Netbeans on OSX?

  - by moorej

  How do I view directories that begin with dot and how do I browse application directories in Netbeans? I can't seem to view directories that begin with a "dot" through the open file dialog in Netbeans. Similarly, I can't browse any application directory e.g. File-Open File-"someapp.app". Attempting to browse "someapp.app" gives the error "someapp.app is a directory". Altering or removing the regex under Preferences-Miscellaneous-File-Ignored Files Pattern has no effect; directories that begin with dot stay invisible. I'm on OSX 10.5.8 and I've tried to get this working on netbeans 6.5-6.8 to no avail. I posted this to the on the netbeans irc and mailing list but haven't heard anything back. Any help would be appreciated!

• Unable to connect to a local MYSQL server on wireles LAN.

  - by Arnab

  Ok, Here is the technical description. My laptop's config: Ip Adress:192.168.2.5 Mysqlserver 5.0 on port : 3306 Operating system: Ubuntu jaunty (9.04) 3306 is open for both incoming and outgoing. My friend's laptop config: Ip Adress:192.168.2.4 Mysqlserver 5.0 on port : 3306 Operating system: Windows XP pro 3306 is open for both incoming and outgoing. Both are on a wireless LAN connected through a belkin router (192.168.2.1) Both the MYSQL servers have been given the sufficient GRANT privileges. I am also able to connect from 192.168.2.4 to 192.168.2.5's MYSQL instance but the vice versa is not happening. I am getting an (100061) error. Tried Telnetting on 3306; again happening from 192.168.2.4 to 192.168.2.5 but not the vice versa. Am I doing something wrong? Kindly suggest.

• perl split on empty file

  - by Casey

  I have basically the following perl I'm working with: open I,$coupon_file or die "Error: File $coupon_file will not Open: $! \n"; while (<I>) { $lctr++; chomp; my @line = split/,/; if (!@line) { print E "Error: $coupon_file is empty!\n\n"; $processFile = 0; last; } } I'm having trouble determining what the split/,/ function is returning if an empty file is given to it. The code block if (!@line) is never being executed. If I change that to be if (@line) than the code block is executed. I've read information on the perl split function over at http://perldoc.perl.org/functions/split.html and the discussion here about testing for an empty array but not sure what is going on here. I am new to Perl so am probably missing something straightforward here. Thanks.

• Ctrl+Click / Command+Click not working with analytics

  - by user347998

  Hi All, I created my own analytics for my site to track outbound click events using jquery. Now the thing with preventDefault() is that it does not allow for the Ctrl+Click or COmmand+click operation in the browser to open the link in new tab/window. So my solution was to detect e.metaKey || e.ctrlKey and use window.open. This does not work very great with safari unless the user changes browser behavior. I am wondering if anyone here knows what other analytics users do - like how does google etc deal with this problem in tracking outbound links? From this link: http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55527 - looks like google will also face the same problem. Thoughts?

• Using one sqlconnection/sqlcommand through 2 DB-bound methods

  - by dotnetdev

  I have a class with a method which gets data from a database through a SELECT stored proc. This method uses a SqlDbReader by returning ExecuteReader() on a SqlCommand. The connection and everything is made in this method, with fields (such as connection string) set as class level fields. I now need to populate an array based on the results of this query (so the columns of each row will go into the array with its own index). However, this query will not select all of the data from one table which is involved. I can write the queries to get what I need, but how can I use one connection throughout the class? If I instantiate the connection object and call Open() in the constructor, I get an exception @ runtime. I'm hoping for something like this: // At class level: sqlconn.Open(); // sqlcommand set up Method() { // Fire stored proc // Insert results in a collection } Method2() { // Pass same collection in (use same one), // Add new row columns into same collection } How can I do this with strict performance in mind? Thanks

• Sharepoint checkin/checkout

  - by Prashanth

  We have a sharepoint based application that uses a custom database for storing metadata/files (which could also be on a file share) My question is how can the standard file checkin/check out option in document library be customized? The javascript file ows.js in the layouts folder contains the functions that provide checkin/check out/ open file functionality. Behind the scenes it relies on a combination of HTTP Post/GET methods + SOAP + an activeX control to achieve the desired functionality. Customizing these javascript function seems tedious/error prone. Note that we have a web service that exposes endpoints, for retrieving necessary file information/data from the backend. The difficulty is in integrating it with the sharepoint js functions, due to lack of proper documentation. (Also the js functions might change over different versions of sharepoint) Also is it possible to create files/open files etc from the cache area on the client machine from server side code?

• Why Read In UTF-16LE File Won't Convert "\r\n" Into "\n" In Windows

  - by Dbger

  I am using Perl to read UTF-16LE files in Windows 7. If I read in an ascii file with following code: open CUR_FILE, "<", $asciiFile; Then each "\r\n" in file will be converted into a "\n" in memory; if I read in an UTF-16LE(windows 1200) file with following code: open CUR_FILE, "<:encoding(UTF-16LE)", $utf16leFile; Then "\r\n" will keep unchanged. This inconsistency cause problems when I trying to regexp lines with line breaks. My questions is: Is this how unicode works in Perl & Windows? Or Am I using the wrong code? Thanks so much!

• Print ms access data in vb.net

  - by user225269

  How do I print the ms access data(.mdb) in vb.net? Here is the code that I'm using to view the data in the form. What I want to do is to be able to print what is currently being viewed. Perhaps automatically save the .pdf file and the pdf viewer installed on the system will open that newly generated pdf file Dim cn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\search.mdb") Dim cmd As OleDbCommand = New OleDbCommand("Select * from GH where NAME= '" & TextBox6.Text & "' ", cn) cn.Open() Dim rdr As OleDbDataReader rdr = cmd.ExecuteReader If rdr.HasRows Then rdr.Read() NoAcc = rdr("NAME") If (TextBox6.Text = NoAcc) Then TextBox1.Text = rdr("IDNUMBER") If (TextBox6.Text = NoAcc) Then TextBox7.Text = rdr("DEPARTMENT") If (TextBox6.Text = NoAcc) Then TextBox8.Text = rdr("COURSE") End If -some sites for beginners regarding this topic would help a lot:)

• "Look" of page changes a bit after uploading it to IIS - looks good on computer same IE8

  - by J Smith

  No it's not a path issue...or else the site won't have a design. The website looks fine if I open it with IE8 in my computer. But after I upload it to IIS 6.0 two things change on positioning. I see a rendering problem. But if I open it with IE 8.0 on my machine it looks good, but opening it when uploaded to IIS , it changes a bit. Same exact files. Same browser, same computer. The only different thing is that it has been uploaded to IIS. IT has no programming in aspx whatsoever just .html .css and .js
