  • how to download vim script in command line

    - by HaiYuan Zhang
    whenever I want to install a new vim script to the linux server I'm working in , my typical workflow is as the following: surf the plugin's homepage in vim online using fireXXXX download a right version of the plugin to my laptop by click some highlighted link upload the downloaded plugin from my laptop to linux server using winscp which is really inconvenient. I don't know what is the magic behind this : I mean for the same hyperlinki click it in web browser I can let you download it but use wget plus the hyperlink in linux commandline will end up with nothing but error indication. hyperlink in web browser . otherwise I can get the link in web browser and then use wget or some similar tool to actually do the downloding. I try new cool vim scripts quite often , so you can imagin my dismay when have to repeat the tedious action all the time. So if anyone of you knows some tips which can let me downloading the vim scripts in a more "professional" way, I'll appreciate it a lot. post edit : My problem is not find a tool like wget or curl . The problem I met is quite specific to use these tools to download vim script. let's take http://www.vim.org/scripts/script.php?script_id=30 as an example, it's the normal place where one can get the script, at least for me. but I can't find an working url from this page that can feed to wget .

  • Problem with derived ControlTemplates in WPF

    - by Frank Fella
    The following xaml code works: <Window x:Class="DerivedTemplateBug.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:DerivedTemplateBug" Title="Window1" Height="300" Width="300"> <Button> <Button.Template> <ControlTemplate> <Border BorderBrush="Black" BorderThickness="2"> <TextBlock>Testing!</TextBlock> </Border> </ControlTemplate> </Button.Template> </Button> </Window> Now, if you define the following data template: using System.Windows.Controls; namespace DerivedTemplateBug { public class DerivedTemplate : ControlTemplate { } } And then swap the ControlTemplate for the derived class: <Window x:Class="DerivedTemplateBug.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:DerivedTemplateBug" Title="Window1" Height="300" Width="300"> <Button> <Button.Template> <local:DerivedTemplate> <Border BorderBrush="Black" BorderThickness="2"> <TextBlock>Testing!</TextBlock> </Border> </local:DerivedTemplate> </Button.Template> </Button> </Window> You get the following error: Invalid ContentPropertyAttribute on type 'DerivedTemplateBug.DerivedTemplate', property 'Content' not found. Can anyone tell me why this is the case?

  • C# "Enum" Serialization - Deserialization to Static Instance

    - by Walt W
    Suppose you have the following class: class Test : ISerializable { public static Test Instance1 = new Test { Value1 = "Hello" ,Value2 = 86 }; public static Test Instance2 = new Test { Value1 = "World" ,Value2 = 26 }; public String Value1 { get; private set; } public int Value2 { get; private set; } public void GetObjectData(SerializationInfo info, StreamingContext context) { //Serialize an indicator of which instance we are - Currently //I am using the FieldInfo for the static reference. } } I was wondering if it is possible / elegant to deserialize to the static instances of the class? Since the deserialization routines (I'm using BinaryFormatter, though I'd imagine others would be similar) look for a constructor with the same argument list as GetObjectData(), it seems like this can't be done directly . . Which I would presume means that the most elegant solution would be to actually use an enum, and then provide some sort of translation mechanism for turning an enum value into an instance reference. How might one go about this?

  • Does Len function only evaluate numerical results?

    - by Mel
    Why does the following code not output "Error" if the form is submitted with a blank field? Does Len only evaluate numerical values? <cfif NOT Len(Trim("Form.myField"))> <cfoutput>Error</cfoutput> </cfif> The following also does not evaluate as expected: <cfif Len(Trim("Form.myField")) IS 0> <cfoutput>Error</cfoutput> </cfif> HTML: <input type="text" name="myField" value="">

  • Problems with MySQL OR clause

    - by Simon
    I have a problem with AND and OR clause in SQL. Here is my query: SELECT `act1`.`name`, `act1`.`surname`, `act2`.`name`, `act2`.`surname`, `act3`.`name`, `act3`.`surname` FROM `videos`, `actors` AS act1, `actors` AS act2, `actors` AS act3 WHERE `videos`.`ident` = 'somethink' AND ( `act1`.`id` = `videos`.`id_actor1` OR `act2`.`id` = `videos`.`id_actor2` OR `act3`.`id` = `videos`.`id_actor3` ) It returns me all variations of {name, surname}, but I want the name and surname of first exactly, second and thirth, if they exist.

  • Visual Studio 2008 freeze after save

    - by Klay
    I recently added about a dozen classes from another solution into my current solution in Visual Studio. After adding these classes, Visual Studio started freezing for about 10 seconds whenever I Save. The cursor disappears and mouse clicks and keys do nothing. Some interesting points: Even after I removed the classes, the freezing behavior is still there. Freezing occurs whether I've made changes to the code or not. This behavior ONLY seems to affect this particular version of this solution. No other solutions exhibit this behavior. Older versions of this solution are not affected. In Sysinternals Process Explorer, whenever I save in Visual Studio, the I/O bytes graph jumps from 0 to 2MB for about 5 seconds, then drops to about 1 MB for a split second, then jumps back to 2MB for another 5 seconds. Processor use goes up to about 3-5% during this time. Here are the details of my setup: C# Silverlight project (maybe 20 classes), .NET version 3.5 SP1, Visual Studio 2008 v9.0.30729 SP1. EDIT: I edited this question extensively to reflect the more detailed information. I thought this might be preferable to starting a new question.

  • UITextField in UIAlertView doesn't respond to cut/copy/paste on second showing

    - by Jesse Grosjean
    I"m adding a UITextView to a UIAlertView with the following code: UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter Name Here" message:@"this gets covered!" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"OK!", nil]; UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)]; CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60); [alert setTransform:myTransform]; [myTextField setBackgroundColor:[UIColor whiteColor]]; [alert addSubview:myTextField]; [alert show]; [alert release]; [myTextField release]; If I place that code in a standard action method: - (IBAction)testAlertView:(id)sender { ...the above code... } Then the first time I show the alert view the cut/copy/paste popup menu will show in the text fields that's been added to the alert view. (For instance if I tap and hold, then "Paste" will popup after I release. The problem is after working correctly the first time, none of the cut/copy/paste buttons will show up again when I show the alert view unless I restart the app. Does anyone know why, or how to fix this problem? Bonus information I just found out that I can get things to always work if I create an show the alert within a UIActionSheet delagate callback. For instance this always works (cut/copy/paste always shows up when in the UITextField when appropriate) - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { ...the above code... } Any idea what might be happening in this second case that make things work? I don't want to use a UIActionSheet in my app, so I'd like to find a way to make it work from a plain old action method. Thanks, Jesse

  • NSButton Aligned to the Right

    - by dave-gennel
    Hi, I want to have a check box, like the standard one (first the check box and on the right its title) but I want it to be aligned from the right. If I change the alignment to the right then only the text will move to the right but the button itself will still be at the left.. How would I achieve this without knowing the bounds of the NSButton? Thanks in advance.

  • How do i make form data not disappear after hitting refresh?

    - by acidzombie24
    I went to test my page on another browser. On google chrome i can fill out a form, hit back and forward and still have the data there. Now i need to refresh the page so certain data is correct (such as session id if the cookie expires or user logs out before submitting). I refresh and lose all data. Is there some option i can set so all data is kept?

  • Indesign and XML - how to auto flow into multiple pages with differing styles?

    - by MetaDan
    Hi guys, I've got a bit of a problem at the moment. I'm trying to work with indesign (cs3) and xml. Basically i have a template which is has 1 master dps, both pages have the same data (fields 1-5) but one is left aligned, one right - hence mildly different paragraph styles. What i want to be able to do is import xml and have indesign flow the data from the individual nodes into many pages. eg xml format: root day field1 field2 field3 field4 field5 day field1 field2 field3 field4 field5 day ... I can almost make this work by tagging the frames on the master pages, then creating pages and importing the xml, however it only flows the first 2 nodes into the pages reptitively for the total count of all the nodes. I can also almost make it work by creating a page from the untagged masters and then tagging the frames with the field1-5 tags then importing the xml. This populates the first page, however i then can't find a way to make the rest of the data flow into new pages... Am I missing something? Am I being a complete dumbass? If anyone can offer any help it will be greatly appreciated...

  • Codaset, Codebasehq, Unfuddle, Trac or Redmine?

    - by Alex
    I have a handful of small Git repositories I would like to host remotely. They're all private projects, most of them in Java. Codaset, Codebasehq, Unfuddle, Trac, Redmine.. There seems to be an abundance of solutions out there. They're all packed with features and useful functionality. Putting aside pricing and the glossy layouts, what is the best way of comparing these options?

  • Make PATH variable changes permanent on openSuse

    - by Marlon
    Okay, so I'm trying to do something that should be rather simple but for some reason I can't quite seem to make it work. All I simply want to do is add a path to the PATH environment variable in openSuse. So far, I've edited the following line in /etc/default/su : PATH=/usr/local/bin:/bin:/usr/bin with this line : PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/php/bin:/usr/local/mysql/bin Basically, all I want to do is have access to php and mysqld regardless of how I log in directly from the command prompt without having to type trailing /usr/local/php/bin/ every time. Am I even editing the right file? I'm a bit of a Linux newbie and to achieve something as trivial as this is eluding me. Server gods out there, drop be a crumb, please? :-)

  • MySQL replication Slave_IO_Running: No

    - by Christy
    Hi all, I have two servers that I am trying to get replication of one database between. I found a setup guide on sourceforge that I followed and I have tried various other settings since then, but no matter what I do, when I start the slave, the 'Slave_IO_Running' setting is always No.... I have no idea why or what to look at, any suggestions are appreciated. The slave setup was: CHANGE MASTER TO MASTER_HOST='myserver.mydomain.net', MASTER_USER='slave_user', 'MASTER_PASSWORD='mypassword', 'MASTER_LOG_FILE='mysql-bin.000011', MASTER_LOG_POS=1368363 (last data from today, trying to do setup again. I deleted and recreated the database on the slave from a new dump and tried to redo the setup.) I have slave_user setup for %, localhost, and the specific IP of the slave computer but nothing seems to be working... Thanks in advance for any advice or suggestions

  • Move 53,800+ files into 54 separate folders with ~1000 files each?

    - by ane
    Trying to import 53,800+ individual files (messages) using Gmail's POP fetcher. Gmail understandably refuses, giving the error: "Too many messages to download. There are too many messages on the other server." The folder in question looks like similar to: /usr/home/customer/Maildir/cur/1203672790.V57I586f04M867101.mail.net:2,S /usr/home/customer/Maildir/cur/1203676329.V57I586f22M520117.mail.net:2,S /usr/home/customer/Maildir/cur/1203677194.V57I586f26M688004.mail.net:2,S /usr/home/customer/Maildir/cur/1203679158.V57I586f2bM182864.mail.net:2,S /usr/home/customer/Maildir/cur/1203680493.V57I586f33M740378.mail.net:2,S /usr/home/customer/Maildir/cur/1203685837.V57I586f0bM835200.mail.net:2,S /usr/home/customer/Maildir/cur/1203687920.V57I586f65M995884.mail.net:2,S ... Using the shell (tcsh, sh, etc. on FreeBSD), what one-line command can I type to split this directory full of files into separate folders so Gmail only sees 1000 messages at a time? Something with find or ls | xargs mv maybe. Whatever is fastest. The desired output directory would now look something like: /usr/home/customer/Maildir/cur/1203672790.V57I586f04M867101.mail.net:2,S /usr/home/customer/Maildir/cur/1203676329.V57I586f22M520117.mail.net:2,S ... /usr/home/customer/set1/ (contains messages 1-1000) /usr/home/customer/set2/ (contains messages 1001-2000) /usr/home/customer/set3/ (etc.) Ideally, cron could run another command to automatically reverse the process in 1000 message increments every hour. So Gmail only sees & downloads 1000 at a time.

  • How can I start an off PC remotely?

    - by serena
    I am using Team Viewer to control my PCs remotely. It lets me restart my PC, and this is a good feature. Is it possible to remotely start a PC which is already turned off? Maybe it's impossible but I like to ask Superusers. All I can think of is something like sending a signal to PC's BIOS. Assume that all components of PC is connected to electrical socket and the router is on.

  • MacBook hangs when restarting to Vista through BootCamp

    - by John
    I have Vista Pro installed on my Macbook and while it mostly works well, sometimes when I select Windows from the boot screen after turning the thing on, the screen just goes black and it all stops. If I hold the power button until it powers down and repeat, it works. It's not getting as far as Windows at all, I think, because if Windows was previously shut down to Hibernate, it still restores fine... and I'm pretty sure if Windows' startup had hung and been force-rebooted my session would be borked?

  • Do a database query on Textbox onblur event

    - by user279521
    I am using asp.net 3.5 with C#. I need to do a database lookup when a user enters ProductID in txtProductID. I guess doing javascript is out of the question since this will have to be server side call. I wrote this code in the page_load event of the webpage: protected void Page_Load(object sender, EventArgs e) { txtProductID.Attributes.Add("onblur", "LookupProduct()"); } protected void LookupUser() { //Lookup Product information on onBlur event; } I get an error message: Microsoft JScript runtime error: Object expected How can I resolve this ?

  • Please explain syntax rules and scope for "typedef"

    - by unknown google user
    What are the rules? OTOH the simple case seems to imply the new type is the last thing on a line. Like here Uchar is the new type. typedef unsigned char Uchar; But a function pointer is completely different. Here the new type is pFunc: typedef int (*pFunc) (int); I can't think of any other examples offhand but I have come across some very confusing usages. So are there rules or are people just suppose to know from experience that this is how it is done because they have seen it done this way before? ALSO: What is the scope of a typedef. Thanks to everyone.
