  • Remote desktop type software that the client need not install anything...

    - by allentown
    I am primarily a Macintosh user, and can usually walk a client though any troubles they may have because I have a Macintosh in front of me. If they are on a different OS, things are close enough, or I cam remember, that I can get by. When trying to help clients on Windows, I get stuck. I do not have access to windows, and even if I did, there are far too many versions of Outlook, all with their various esoteric settings and checkboxes, that I could never see exactly what they are seeing. I mostly need to just help them with email setup. Something like copilot.com may do the trick. What is the simplest remote control software out there, ideally, it would accomplish these: No software needed on remote end, or, a single .exe that they can toss when done. I need Mac based software on my end. I do have ARD, which support VNC Free :) If possible, it would be really nice Needs a port forwarding proxy run by the company. There is no way I can get the user to alter their router, or to even plug directly into their WAN for a short time. On the Mac, I just have them open iChat, and this is all built in, proxying through AIM, looking for the same for Windows and Mac.

  • Ubuntu: Multiple NICs, one used only for Wake-On-LAN

    - by jcwx86
    This is similar to some other questions, but I have a specific need which is not covered in the other questions. I have an Ubuntu server (11.10) with two NICs. One is built into the motherboard and the other is a PCI express card. I want to have my server connected to the internet via my NAT router and also have it able to wake from suspend using a Magic Packet (henceforth referred to as Wake-On-LAN, WOL). I can't do this with just one of the NICs because each has an issue - the built-in NIC will crash the system if it is placed under heavy load (typically downloading data), whilst the PCI express NIC will crash the system if it is used for WOL. I have spent some time investigating these individual problems, to no avail. My plan is thus: use the built-in NIC solely for WOL, and use the PCI express card for all other network communication except WOL. Since I send the WOL Magic Packet to a specific MAC address, there is no danger of hitting the wrong NIC, but there is a danger of using the built-in NIC for general network access, overloading it and crashing the system. Both NICs are wired to the same LAN with address space 192.168.0.0/24. The built-in ethernet card is set to have interface name eth1 and the PCI express card is eth0 in Ubuntu's udev persistent rules (so they stay the same upon reboot). I have been trying to set this up with the /etc/network/interfaces file. Here is where I am currently: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.3 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 auto eth1 iface eth1 inet static address 192.168.0.254 netmask 255.255.255.0 I think by not specifying a gateway for eth1, I prevent it being used for outgoing requests. I don't mind if it can be reached on 192.168.0.254 on the LAN, i.e. via SSH -- it's IP is irrelevant to WOL, which is based on MAC addresses -- I just don't want it to be used to access internet resources. My kernel routing table (from route -n) is Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 100 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 My question is this: Is this sufficient for what I want to achieve? My research has thrown up the idea of using static routing to specify that eth1 should only be used for WOL on the local network, but I'm not sure this is necessary. I have been monitoring the activity of the interfaces using iptraf and it seems like eth0 takes the vast majority of the packets, though I am not sure that this will be consistent based on my configuration. Given that if I mess up the configuration, my system will likely crash, it is important to me to have this set up correctly!

  • CLI package to replace Plesk

    - by dotancohen
    Myself and another programmer are tasked with maintaining a few webservers. I prefer CLI tools, she prefers Plesk. However, I am adamant about not installing Plesk for quite a few reasons. I have written a small Python script for adding new domains, and now I am about to add the ability to configure email addresses while abstracting the details of Postfix from her. Before I go that route, I have googled to see if anything already exists, and am surprised that I have come up with nothing! Are there any mature, stable "control panels" or "server admin" tools like Plesk, but which are accessed via the CLI over SSH? I am looking for the following features: Add / remove / configure domains served by Apache. Add / remove / configure email boxes and mail groups. Add / remove MySQL databases, users, and configure users to databases. Provide basic monitoring of "server health", that is: memory usage, disk usage, CPU usage, bandwidth usage. Possibly set up STFP accounts so that only specific FTP users could access specific /var/www/someSite/ directories. Note that I was unsure if this question is OT for ServerFault. As per the ServerFault about page (There seems to be no more FAQ) this question meets two of the "ask about" criterion and zero of the "don't ask about" with the possible exception of being opinion-based. Therefore, to keep on-topic, I would like to know about the available applications but we should be subjective and less opinionated. Thank you!

  • Mapping capslock to control on Mac OS X: works for some things, but not others?

    - by keflavich
    I've mapped my capslock key to control using the Modifier Keys mapping in System Preferences: Keyboard. I've also tried mapping to "right control" instead of "left control" as per http://hints.macworld.com/article.php?story=20060825072451882 using a plist editor. The mapping seems to work in all cases except one: I can't use capslock with left-shift to make key mappings or apparently do anything else. capslock (as control) with right-shift works. I'm primarily testing by using control-tab / control-shift-tab to switch between tabs. Using the on-screen-keyboard viewer, I can get capslock-shift-(just about anything) to work, but not capslock-leftshift-tab. My best guess is that somehow the particular keyboard I'm working on is faulty, but I'm curious whether anyone else can reproduce this or has any ideas.

  • Unexpected multiple network connections on Windows Vista

    - by Jens
    My Network and Sharing Center shows multiple connections to the internet, where only one is expected: My internet access works fine, but since the "Unidentified Network" is set to public after each boot, sharing and network discovery don't work as well. Similar questions on Google point mostly to the Bonjour service, but I am sure that this is not, and never was, installed on this machine. So: How can I get rid of the unidentified network?

  • Windows 7, enabeling IE for removal

    - by Thew
    For a while now, Windows Update has been prompting me to update IE9 to IE10. And every time I turn off my PC, It starts to install that one update wich allways fails. Why does it fail updating IE9? I don't know. So the solution I had in my mind was to remove IE9 and then install IE10 manually. THe problem is now, I can't find the uninstall file for IE9. I have looked in windows control panel / programs and features but it didn't show up, not even in the installed updates section. So after I clicked on Turn windows features on or off, I saw that the IE9 box wasn't checked. So I checked it, clicked OK, but then when I clicked on the Turn windows features on or off link again, it wasn't checked anymore. It's almost like Windows doesn't want me to uninstall IE9. but I have to in order to normally shut down my pc, because everytime I shut my PC off, it tries to install that stupid update again! What can I do to solve this?

  • How to configure SVN server for my own project

    - by user1729952
    I work with a team on an Android project using Eclipse IDE, we need to use a version control and we need to access the repo remotely, I have no experience using or installing servers, a little experience using SVN on Windows, but I still have problems connecting to it remotely. I need to use no-ip.com to change my IP, however; I failed to make VisualSVN server to work with no-ip. What options do I have? The best thing is to get it work with Windows if not, I have another computer that is running Ubuntu 12.4.1, I have installed apache2svn on it trying to get it work, the svn is installed, I went through tutorials to configure accessing protocols, but I can't figure out how to access it remotely from another computer? Can someone tell me the steps I need to get this job done and I can do my search for each step? (Please explain each step as some keywords or phrases I may not be familiar with) EDIT: Also worth noting, that my company has a website hosted on a remote server, can we use it as a repo? and how? It's running Linux

  • (SQL) Selecting from a database based on multiple pairs of pairs

    - by Owen Allen
    The problem i've encountered is attempting to select rows from a database where 2 columns in that row align to specific pairs of data. IE selecting rows from data where id = 1 AND type = 'news'. Obviously, if it was 1 simple pair it would be easy, but the issue is we are selecting rows based on 100s of pair of data. I feel as if there must be some way to do this query without looping through the pairs and querying each individually. I'm hoping some SQL stackers can provide guidance. Here's a full code break down: Lets imagine that I have the following dataset where history_id is the primary key. I simplified the structure a bit regarding the dates for ease of reading. table: history history_id id type user_id date 1 1 news 1 5/1 2 1 news 1 5/1 3 1 photo 1 5/2 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 If the user wants to select rows from the database based on a date range we would take a subset of that data. SELECT history_id, id, type, user_id, date FROM history WHERE date BETWEEN '5/3' AND '5/5' Which returns the following dataset history_id id type user_id date 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 Now, using that subset of data I need to determine how many of those entries represent the first entry in the database for each type,id pairing. IE is row 4 the first time in the database that id: 3, type: news appears. So I use a with() min() query. In real code the two lists are programmatically generated from the result sets of our previous query, here I spelled them out for ease of reading. WITH previous AS ( SELECT history_id, id, type FROM history WHERE id IN (1,2,3,4) AND type IN ('news','photo') ) SELECT min(history_id) as history_id, id, type FROM previous GROUP BY id, type Which returns the following data set. history_id id type user_id date 1 1 news 1 5/1 2 1 news 1 5/1 3 1 photo 1 5/2 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 You'll notice it's the entire original dataset, because we are matching id and type individually in lists, rather than as a collective pairs. The result I desire is, but I can't figure out the SQL to get this result. history_id id type user_id date 1 1 news 1 5/1 4 3 news 1 5/3 5 4 news 1 5/3 7 2 photo 1 5/4 Obviously, I could go the route of looping through each pair and querying the database to determine it's first result, but that seems an inefficient solution. I figured one of the SQL gurus on this site might be able to spread some wisdom. In case I'm approaching this situation incorrectly, the gist of the whole routine is that the database stores all creations and edits in the same table. I need to track each users behavior and determine how many entries in the history table are edits or creations over a specific date range. Therefore I select all type:id pairs from the date range based on a user_id, and then for each pairing I determine if the user is responsible for the first that occurs in the database. If first, then creation else edit. Any assistance would be awesome.

  • What is the right way to process inconsistent data files?

    - by Tahabi
    I'm working at a company that uses Excel files to store product data, specifically, test results from products before they are shipped out. There are a few thousand spreadsheets with anywhere from 50-100 relevant data points per file. Over the years, the schema for the spreadsheets has changed significantly, but not unidirectionally - in the sense that, changes often get reverted and then re-added in the space of a few dozen to few hundred files. My project is to convert about 8000 of these spreadsheets into a database that can be queried. I'm using MongoDB to deal with the inconsistency in the data, and Python. My question is, what is the "right" or canonical way to deal with the huge variance in my source files? I've written a data structure which stores the data I want for the latest template, which will be the final template used going forward, but that only helps for a few hundred files historically. Brute-forcing a solution would mean writing similar data structures for each version/template - which means potentially writing hundreds of schemas with dozens of fields each. This seems very inefficient, especially when sometimes a change in the template is as little as moving a single line of data one row down or splitting what used to be one data field into two data fields. A slightly more elegant solution I have in mind would be writing schemas for all the variants I can find for pre-defined groups in the source files, and then writing a function to match a particular series of files with a series of variants that matches that set of files. This is because, more often that not, most of the file will remain consistent over a long period, only marred by one or two errant sections, but inside the period, which section is inconsistent, is inconsistent. For example, say a file has four sections with three data fields, which is represented by four Python dictionaries with three keys each. For files 7000-7250, sections 1-3 will be consistent, but section 4 will be shifted one row down. For files 7251-7500, 1-3 are consistent, section 4 is one row down, but a section five appears. For files 7501-7635, sections 1 and 3 will be consistent, but section 2 will have five data fields instead of three, section five disappears, and section 4 is still shifted down one row. For files 7636-7800, section 1 is consistent, section 4 gets shifted back up, section 2 returns to three cells, but section 3 is removed entirely. Files 7800-8000 have everything in order. The proposed function would take the file number and match it to a dictionary representing the data mappings for different variants of each section. For example, a section_four_variants dictionary might have two members, one for the shifted-down version, and one for the normal version, a section_two_variants might have three and five field members, etc. The script would then read the matchings, load the correct mapping, extract the data, and insert it into the database. Is this an accepted/right way to go about solving this problem? Should I structure things differently? I don't know what to search Google for either to see what other solutions might be, though I believe the problem lies in the domain of ETL processing. I also have no formal CS training aside from what I've taught myself over the years. If this is not the right forum for this question, please tell me where to move it, if at all. Any help is most appreciated. Thank you.

  • Passing multiple parameters in an MVC Ajax.ActionLink

    - by mwright
    I am using an Ajax.ActionLink to call an Action in a Controller, nothing special there. I want to pass two parameters to the Action. Is this possible using an Ajax.ActionLink? I thought that it would just be a matter of including multiple values in the AjaxOptions: <%= Ajax.ActionLink("Link Text", "ActionName", "ControllerName", new { firstParameter = firstValueToPass, secondParameter = secondValueToPass }, new AjaxOptions{ UpdateTargetId = "updateTargetId"} )%> Is it possible to pass multiple parameters? Where is a good place to learn more about the AjaxOptions?

  • Defining multiple values in DefineConstants in MsBuild element?

    - by Sardaukar
    I'm currently integrating my Wix projects in MSBuild. It is necessary for me to pass multiple values to the Wix project. One value will work (ProductVersion in the sample below). <Target Name="BuildWixSetups"> <MSBuild Condition="'%(WixSetups.Identity)'!=''" Projects="%(WixSetups.Identity)" Targets="Rebuild" Properties="Configuration=Release;OutputPath=$(OutDir);DefineConstants=ProductVersion=%(WixSetups.ISVersion)" ContinueOnError="true"/> </Target> However, how do I pass multiple values to the DefineConstants key? I've tried all the 'logical' separators (space, comma, semi-colon, pipe-symbol), but this doesn't work. Has someone else come across this problem? Solutions that don't work: Trying to add a DefineConstants element does not work because DefineConstants needs to be expressed within the Properties attribute.

  • jstree dynamic JSON data from django

    - by danspants
    I'm trying to set up jsTree to dynamically accept JSON data from django. This is the test data i have django returning to jstree: result=[{ "data" : "A node", "children" : [ { "data" : "Only child", "state" : "closed" } ], "state" : "open" },"Ajax node"] response=HttpResponse(content=result,mimetype="application/json") this is the jstree code I'm using: jQuery("#demo1").jstree({ "json_data" : { "ajax" : { "url" : "/dirlist", "data" : function (n) { return { id : n.attr ? n.attr("id") : 0 }; }, error: function(e){alert(e);} } }, "plugins" : [ "themes","json_data"] }); All I get is the ajax loading symbol, the ajax error response is also triggered and it alerts "undefined". I've also tried simpleJson encoding in django but with the same result. If I change the url so that it is receiving a JSON file with identical data, it works as expected. Any ideas on what the issue might be?

  • WinForms Web Browser control forcing refocus?

    - by Corey Ogburn
    I'm trying to automate a web process where I need to click a button repeatedly. When my code "clicks" that button (an HtmlElement obtained from the WebBrowser control I have on my form) then it brings focus back to my application, more specifically the WebBrowser control. I wish to better automate this process so that the user can do other things while the process is going on, but that can't happen if the window is unminimizing itself because it's attaining focus. The code associated with the clicking is: HtmlElement button = Recruiter.Document.GetElementById("recruit_link"); button.InvokeMember("click"); I've also tried button.RaiseEvent("onclick") and am getting the exact same results, with focus problems and all. I've also tried hiding the form, but when the InvokeMember/RaiseEvent method is called, whatever I was working on loses focus but since the form is not visible then the focus seems to go nowhere. The only non-default thing about the webbrowser is it's URI being set to my page and ScriptErrorsSuppressed being set to True.

  • RowFilter.regexFilter multiple columns

    - by twodayslate
    I am currently using the following to filter my JTable RowFilter.regexFilter( Pattern.compile(textField.getText(), Pattern.CASE_INSENSITIVE).toString(), columns ); How do I format my textField or filter so if I want to filter multiple columns I can do that. Right now I can filter multiple columns but my filter can only be of one of the columns An example might help my explanation better: Name Grade GPA Zac A 4.0 Zac F 1.0 Mike A 4.0 Dan C 2.0 The text field would contain Zac A or something similar and it would show the first Zac row if columns was int[]{0, 1}. Right now if I do the above I get nothing. The filter Zac works but I get both Zac's. A also works but I would then get Zac A 4.0 and Mike A 3.0. I hope I have explained my problem well. Please let me know if you do not understand.

  • Git subtree not properly using .gitignore when doing a partial clone

    - by D W
    I am a graduate student with many scripts, bibliography data in bibtex, thesis draft in latex, presentations in open office, posters in scribus, and figures and result data. I would like to put everything in one project under version control. Then when I need to work on a portion such as the bibliography data, I would like to check that subdirectory out, modify it as necessary and merge it back.I would like the ability to check out one version to my home computer, and a different one to my work computer and make changes to each independently and eventually merge them back. I would also like to be able to check out a piece of code from this big project and import it with versioning into a separate project. If I may changes I'd like to be able to merge them back to the original project. Based on my understanding git subtree can do this. http://github.com/apenwarr/git-subtree There is an example that is along the lines of what I'm trying to do at: http://psionides.jogger.pl/2010/02/04/sharing-code-between-projects-with-git-subtree/ Say the trunk of my project contained the directories: (bib bin cfg data fig src todo). When I use git subtree split -P bib -b export git checkout export I get a the bib directory, plus all files that should have been ignored or considered binary based on .gitignore such as the src directory and everything in it that ends in a tilde or the ./data directory. dwickrama@DWwork:~/research/trunk$ ls * -r biblography.bib JabRef src: script1.sh~ README~ script2.sh~ script3.sh~ script4.R~ script5.awk~ script5.py~ cfg: cfgFile1.ini~ cfgFile2.ini~ cfgFile3.ini~ bin: bigBinaryPackage1 bigBinaryPackage2 dwickrama@DWwork:~/research/trunk$ My .gitignore file is as follows: *.doc diff=word *.tex diff=tex *.bib diff=bibtex *.py diff=python *.eps binary *.jpg binary *.png binary ./bin/* binary *~ How do I prevent this?

  • How to filter the jqGrid data NOT using the built in search/filter box

    - by Jimbo
    I want users to be able to filter grid data without using the intrinsic search box. I have created two input fields for date (from and to) and now need to tell the grid to adopt this as its filter and then to request new data. Forging a server request for grid data (bypassing the grid) and setting the grid's data to be the response data wont work - because as soon as the user tries to re-order the results or change the page etc. the grid will request new data from the server using a blank filter. I cant seem to find grid API to achieve this - does anyone have any ideas? Thanks.

  • Machine learning challenge: diagnosing program in java/groovy (datamining, machine learning)

    - by Registered User
    Hi All! I'm planning to develop program in Java which will provide diagnosis. The data set is divided into two parts one for training and the other for testing. My program should learn to classify from the training data (BTW which contain answer for 30 questions each in new column, each record in new line the last column will be diagnosis 0 or 1, in the testing part of data diagnosis column will be empty - data set contain about 1000 records) and then make predictions in testing part of data :/ I've never done anything similar so I'll appreciate any advice or information about solution to similar problem. I was thinking about Java Machine Learning Library or Java Data Mining Package but I'm not sure if it's right direction... ? and I'm still not sure how to tackle this challenge... Please advise. All the best!

  • WPF Focus In Tab Control Content When New Tab is Created

    - by Phil Sandler
    I've done a lot of searching on SO and google around this problem, but can't seem to find anything else to try. I have a MainView (window) that contains a tab control. The tab control binds to an ObservableCollection of ChildViews (user controls). The MainView's ViewModel has a method that allows adding to the collection of ChildViews, which then creates a new tab. When a new tab is created, it becomes the active tab, and this works fine. This method on the MainView is called from another ViewModel (OtherViewModel). What I am trying to do is set the keyboard focus to the first control on the tab (an AutoCompleteBox from WPFToolkit*) when a new tab is created. I also need to set the focus the same way, but WITHOUT creating a new tab (so set the focus on the currently active tab). (*Note that there seem to be some focus problems with the AutoCompleteBox--even if it does have focus you need to send a MoveNext() to it to get the cursor in its window. I have worked around this already). So here's the problem. The focusing works when I don't create a new tab, but it doesn't work when I do create a new tab. Both functions use the same method to set focus, but the create logic first calls the method that creates a new tab and sets it to active. Code that sets the focus (in the ChildView's Codebehind): IInputElement element1 = Keyboard.Focus(autoCompleteBox); //plus code to deal with AutoCompleteBox as noted. In either case, the Keyboard.FocusedElement starts out as the MainView. After a create, calling Keyboard.Focus seems to do nothing (focused element is still the MainView). Calling this without creating a tab correctly sets the keyboard focus to autoCompleteBox. Any ideas? Update: Bender's suggestion half-worked. So now in both cases, the focused element is correctly the AutoCompleteBox. What I then do is MoveNext(), which sets the focus to a TextBox. I have been assuming that this Textbox is internal to the AutoCompleteBox, as the focus was correctly set on screen when this happened. Now I'm not so sure. This is still the behavior I see when this code gets hit when NOT doing a create. After a create, MoveNext() sets the focus to an element back in my MainView. The problem must still be along the lines of Bender's answer, where the state of the controls is not the same depending on whether a new tab was created or not. Any other thoughts?

  • qT quncompress gzip data

    - by talei
    Hello, I stumble upon a problem, and can't find a solution. So what I want to do is uncompress data in qt, using qUncompress(QByteArray), send from www in gzip format. I used wireshark to determine that this is valid gzip stream, also tested with zip/rar and both can uncompress it. Code so far, is like this: static const char dat[40] = { 0x1f, 0x8b, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x03, 0xaa, 0x2e, 0x2e, 0x49, 0x2c, 0x29, 0x2d, 0xb6, 0x4a, 0x4b, 0xcc, 0x29, 0x4e, 0xad, 0x05, 0x00, 0x00, 0x00, 0xff, 0xff, 0x03, 0x00, 0x2a, 0x63, 0x18, 0xc5, 0x0e, 0x00, 0x00, 0x00 }; //this data contains string: {status:false}, in gzip format QByteArray data; data.append( dat, sizeof(dat) ); unsigned int size = 14; //expected uncompresed size, reconstruct it BigEndianes //prepand expected uncompressed size, last 4 byte in dat 0x0e = 14 QByteArray dataPlusSize; dataPlusSize.append( (unsigned int)((size >> 24) & 0xFF)); dataPlusSize.append( (unsigned int)((size >> 16) & 0xFF)); dataPlusSize.append( (unsigned int)((size >> 8) & 0xFF)); dataPlusSize.append( (unsigned int)((size >> 0) & 0xFF)); QByteArray uncomp = qUncompress( dataPlusSize ); qDebug() << uncomp; And uncompression fails with: qUncompress: Z_DATA_ERROR: Input data is corrupted. AFAIK gzip consist of 10 byte header, DEFLATE peyload, 12 byte trailer ( 8 byte CRC32 + 4 byte ISIZE - uncompresed data size ). Striping header and trailer should leave me with DEFLATE data stream, qUncompress yields same error. I checked with data string compressed in PHP, like this: $stringData = gzcompress( "{status:false}", 1); and qUncompress uncompress that data.(I didn't see and gzip header though i.e. ID1 = 0x1f, ID2 = 0x8b ) I checked above code with debug, and error occurs at: if ( #endif ((BITS(8) << 8) + (hold >> 8)) % 31) { //here is error, WHY? long unsigned int hold = 35615 strm->msg = (char *)"incorrect header check"; state->mode = BAD; break; } inflate.c line 610. I know that qUncompress is simply a wrapper to zlib, so I suppose it should handle gzip without any problem. Any comments are more then welcome. Best regards

  • idioms for returning multiple values in shell scripting

    - by Wang
    Are there any idioms for returning multiple values from a bash function within a script? http://tldp.org/LDP/abs/html/assortedtips.html describes how to echo multiple values and process the results (e.g., example 35-17), but that gets tricky if some of the returned values are strings with spaces in. A more structured way to return would be to assign to global variables, like foo () { FOO_RV1="bob" FOO_RV2="bill" } foo echo "foo returned ${FOO_RV1} and ${FOO_RV2}" I realize that if I need re-entrancy in a shell script I'm probably doing it wrong, but I still feel very uncomfortable throwing global variables around just to hold return values. Is there a better way? I would prefer portability, but it's probably not a real limitation if I have to specify #!/bin/bash.

  • Add animation when user control get visible and collapsed In Wpf

    - by sanjeev40084
    I have two xaml files MainWindow.xaml and other user control WorkDetail.xaml file. MainWindow.xaml file has a textbox, button, listbox and reference to WorkDetail.xaml(user control which is collapsed). Whenever user enter any text, it gets added in listbox when the add button is clicked. When any items from the listbox is double clicked, the visibility of WorkDetail.xaml is set to Visible and it gets displayed. In WorkDetail.xaml (user control) it has textblock and button. The Textblock displays the text of selected item and close button sets the visibility of WorkDetail window to collapsed. Now i am trying to animate WorkDetail.xaml when it gets visible and collapse. When any items from listbox is double clicked and WorkDetail.xaml visibility is set to visible, i want to create an animation of moving WorkDetail.xaml window from right to left on MainWindow. When Close button from WorkDetail.xaml file is clicked and WorkDetail.xaml file is collapsed, i want to slide the WorkDetail.xaml file from left to right from MainWindow. Here is the screenshot: MainWindow.xaml code: <Window...> <Grid Background="Black" > <TextBox x:Name="enteredWork" Height="39" Margin="44,48,49,0" TextWrapping="Wrap" VerticalAlignment="Top"/> <ListBox x:Name="workListBox" Margin="26,155,38,45" FontSize="29.333" MouseDoubleClick="workListBox_MouseDoubleClick"/> <Button x:Name="addWork" Content="Add" Height="34" Margin="71,103,120,0" VerticalAlignment="Top" Click="Button_Click"/> <TestWpf:WorkDetail x:Name="WorkDetail" Visibility="Collapsed"/> </Grid> </Window> MainWindow.xaml.cs class code: namespace TestWpf { public partial class MainWindow : Window { public MainWindow() { this.InitializeComponent(); } private void Button_Click(object sender, RoutedEventArgs e) { workListBox.Items.Add(enteredWork.Text); } private void workListBox_MouseDoubleClick(object sender, MouseButtonEventArgs e) { WorkDetail.workTextBlk.Text = (string)workListBox.SelectedItem; WorkDetail.Visibility = Visibility.Visible; } } } WorkDetail.xaml code: <UserControl ..> <Grid Background="#FFD2CFCF"> <TextBlock x:Name="workTextBlk" Height="154" Margin="33,50,49,0" TextWrapping="Wrap" VerticalAlignment="Top" FontSize="29.333" Background="#FFF13939"/> <Button x:Name="btnClose" Content="Close" Height="62" Margin="70,0,94,87" VerticalAlignment="Bottom" Click="btnClose_Click"/> </Grid> </UserControl> WorkDetail.xaml.cs class code: namespace TestWpf { public partial class WorkDetail : UserControl { public WorkDetail() { this.InitializeComponent(); } private void btnClose_Click(object sender, System.Windows.RoutedEventArgs e) { Visibility = Visibility.Collapsed; } } } Can anyone tell how can i do this?

  • Setting a WebControls TabIndex based on the ControlId of another control

    - by Daniel Ballinger
    I have an ASP.NET Webforms site that is regularly having features added. The majority of time a new WebControl is added to the page and I need to increment the TabIndex to all subsequent controls on the page. I'd prefer a more robust solution than choosing an arbitrary gap between the initial assigned tab indexes. Setting the tab indexes using the designer tab order functionality is one option but I'd prefer to stay in the source view. Ideally, if I had three check boxes I'd like to be able to define the tabindex based off the previous controls tabindex. Then I'd only need to insert the new control and change one existing control. <asp:CheckBox ID="checkBoxA" runat="server" TabIndex="0"/> <asp:CheckBox ID="checkBoxB" runat="server" TabIndexAfterControlId="checkBoxA"/> <asp:CheckBox ID="checkBoxC" runat="server" TabIndexAfterControlId="checkBoxB"/> My first thought was to extend System.Web.UI.WebControls.WebControl with a new property, but extension properties aren't supported.

  • Where is the WPF Numeric UpDown control?

    - by AngryHacker
    Getting into the first serious WPF project. It seems like there are a lot of basic controls flat out missing. Specifically, I am looking for the Numeric UpDown control. Was there an out of band release that I missed? Really don't feel like writing my own control. I do not want to use the WindowsFormHost and plop a WinForm ctl on it. I want it to be fully WPF without any legacy junk. Thanks

  • SQLPlus - spooling to multiple files from PL/SQL blocks

    - by FrustratedWithFormsDesigner
    I have a query that returns a lot of data into a CSV file. So much, in fact, that Excel can't open it - there are too many rows. Is there a way to control spool to spool to a new file everytime 65000 rows have been processed? Ideally, I'd like to have my output in files named in sequence, such as large_data_1.csv, large_data_2.csv, large_data_3.csv, etc... I could use dbms_output in a PL/SQL block to control how many rows are output, but then how would I switch files, as spool does not seem to be accessible from PL/SQL blocks? (Oracle 10g)
