  • String replacement in PHP

    - by [email protected]
    This is my first question on this wonderful website. Lets say I have a string $a="some text..%PROD% more text" There will be just one %..% in the string. I need to replace PROD between the % with another variable content. So I used to do: $a = str_replace('%PROD%',$var,$a); but now the PROD between % started coming in different cases. So I could expect prod or Prod. So I made the entire string uppercase before doing replacement. But the side effect is that other letters in the original string also became uppercase. Someone suggested me to use regular expression. But how ? Thanks, Rohan

  • Read nested Lua table who key is a System.Double

    - by Robert Kerr
    Using C# and LuaInterface, I am trying to read a nested table, but am getting a null LuaTable when I try to open the key containing the table. The .lua file: DB = { ["inventory"] = { [10001] = { ["row"] = 140, ["count"] = 20, }, [10021] = { ["row"] = 83, ["count"] = 3, }, [10075] = { ["row"] = 927, ["count"] = 15, }, } } I can successfully foreach the entries under inventory, by opening that table with: LuaTable tbl = lua.GetTable("DB.inventory"); foreach (DictionaryEntry de in tbl) ... What I cannot do is open an inventory item and enumerate its entries the same way. Is this because the key is a System.Double type? This fails: LuaTable tbl = lua.GetTable("DB.inventory.10001"); foreach (DictionaryEntry de in tbl) with an exception, because tbl is null. Effectively, once I enumerate the keys (inventory items), I then want to drill down into the nested table and work with those contents. As you can see, I am not able to get a reference to the nested table the way I am doing it.

  • Why is the form action attribute empty on production server?

    - by Ozzy
    After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem: xmlRequest.open("POST", action, true); The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like: <form method="post" action="" id="Form1"> However, on my developer machine I get the following: <form method="post" action="default.aspx" id="Form1"> So, why would the action-attibute render on my dev.machine but not on the production server? This seems to be the case only for one specific web form, when I look on other pages the action-attribute renders correctly. Any suggestions or ideas would be helpful!

  • R: ggplot2, how to add a number of layers to a plot at once to reduce code

    - by John
    library(ggplot2) This code produces a nice looking plot: qplot(cty, hwy, data = mpg, colour = displ) + scale_y_log2() + labs(x="x axis") + labs(y="y axis") + opts(title = "my title") But I want to setup variables to try and to reduce code repetition: log_scale <- scale_y_log2() xscale <- labs(x="x axis") yscale <- labs(y="y axis") title <- opts(title = "my title") my_scales <- c(log_scale, xscale, yscale, title) # make a variable to hold the scale info changes above So that I can do this and add a bunch of things at the same time: qplot(cty, hwy, data = mpg, colour = displ) + my_scales # add these to your plot. but I get this error: Error in object$class : $ operator is invalid for atomic vectors I realize that the things going into my_scales need to be layers / different types of objects, but I don't see what they should be.

  • Memory cleanup on returned array from static method (objective-c)

    - by Michael Bordelon
    In objective-c, I have a utility class with a bunch of static methods that I call for various tasks. As an example, I have one method that returns an NSArray that I allocate in the static method. If I set the NSArray to autorelease, then some time later, the NSArray in my calling method (that is assigned to the returned pointer) losses it's reference because the original form the static method is cleaned up. I can't release the NSArray object in the static method because it needs to be around for the return and assignment. What is the right way to return an object (like the NSArray) from a static class, and have it hang around for the calling class, but then get cleaned up later when it is no longer needed? Do I have to create the object first in the caller and pass in a pointer to the object and then return that same object form the static method? I know this is a basic O-O problem, I just never had this issue in Java and I do not do much C/C++. Thanks for your help.

  • Appscript to write iTunes artwork

    - by Kartik Aiyer

  • How do I avoid an infinite loop when overriding a virtual property?

    - by cbsch
    Is it possible to ignore set and get when I'm assigning to or retrieving a value? In specific, I'm inheriting from a class that has a property declared like this: virtual public Int32 Value { get; set; } What I'd like to do is to override it and do something useful in those set and get's. The problem appears when I override it, I also have to manually assign, or return the value from the property. If I do something like this: override public Int32 Value { get { return this.Value; } set { this.Value = value; // do something useful } Then I'm creating an infinite loop. Is there a way to set or get the value without invoking the code in set and get, or do I have to make a separate name for the actual variable?

  • Drupal auto change user role in module

    - by Marques
    I am trying to write a module that will change a user's permissions once a node form is inserted into the database. I already have a role assigned when a user registers, but i want that role to be changed once they create a 'company' profile in this case which is when they fill out a cck form of 'company_post' type. My code is below... switch ($op) { case 'insert': if ($node->type == 'company_post') { } ? im not sure what to put in the if statement because I don't really know how to reference the users roles or how to change them. ? So my question is what code can I use to change the users current role to a new role? (Both roles are already created in drupal and have seperate permissions)

  • debug javascript in release mode with yui compressions

    - by mickyjtwin
    In our build scripts, we are using YUI compressor to minify/compress javascript and css files. As this combines the js into one file, it needs to be referenced in the Master Layout script, e.g. First question is what is best way to use both, so that if we are developing (in debug mode) it will reference each js file individually? Second question, is once on production, would there be any steps/solution to debugging the javascript on the production server, i.e. conditionallly load the javascript files based on setting a "debug=true" setting in either js or .net?

  • Visual studio winform designer shows design errors as text rather than html

    - by Miki Watts
    All of the sudden, visual studio displays designer errors as plain html text, for example: <DIV id="div1" class="ErrorStyle" width="100%"><span style="font-weight: 600"><br>Object reference not set to an instance of an object. </span><br><a href="" instead of displaying the usual html formatted. I haven't been able to find anything similar to it on google. Before getting this problem, when I tried opening the winform designer, I would get the run/save/cancel dialog of internet explorer for a .tmp file, instead of the designer window. That went away when I found out that I had notepad assigned to the .tmp file type and removed that. Any ideas how to fix this?

  • Need an ASP.NET MVC long running process with user feedback

    - by Jason
    I've been trying to create a controller in my project for delivering what could turn out to be quite complex reports. As a result they can take a relatively long time and a progress bar would certainly help users to know that things are progressing. The report will be kicked off via an AJAX request, with the idea being that periodic JSON requests will get the status and update the progress bar. I've been experimenting with the AsyncController as that seems to be a nice way of running long processes without tying up resources, but it doesn't appear to give me any way of checking on the progress (and seems to block further JSON requests and I haven't discovered why yet). After that I've tried resorting to storing progress in a static variable on the controller and reading the status from that - but to be honest that all seems a bit hacky! All suggestions gratefully accepted!

  • WCF - WebReferences not working

    - by JMSA
    At the client end, I have generated a Proxy using SvcUtil.exe and it is working fine. Then I have added a WebReference to the client assembly and calling the same method. But it is not working. My program is running in console mode and the method is suppose to return a string. It is not returning the string. I just see a blank console window. No exception is thrown. And after setting a debug point on the method call I see that, program is halted on the method call for ever. What should I look for to solve the problem? I am using VS2005. And adding the webReference by right-clicking the client project and then clicking "Add Web Reference" pop-up menu.

  • Nexus: removing repository

    - by David
    Hi, I accidently removed a hosted snapshot repository from Nexus containing a few artifacts needed by other developers on my team. Fine, I'll be able to recreate it fairly easy, but when I tried to add the repository again with the same name as the one I removed, the "Upload Artifact" tab did not show. I tried to clean the cache and reindex the public and public snapshot repos, but that didn't help. I also tried setting an alternative storage path by entering an alternative path on "Override Local Storage Location", same result. Will I have to create a brand new repository with a different name and change all repository reference in my projects? Thanks, David

  • How does one inject variables into page templates from a custom Drupal module?

    - by Michael T. Smith
    We've created a custom module for organizing and publishing our newsletter content. The issue I'm running into now -- and I'm new to theming and Drupal module development, so it could just be a knowledge issue as opposed to a Drupal issue -- is how to get each newsletter themed. At this point the URL structure of our newsletter will be: /newsletters/{newsletter-name}/{edition-name}/{issue-date} which means that we can create template files in our theme using filenames like page-newsletters-{newsletter-name}-{edition-name}.tpl.php, which is great. The one issue I'm running into is that all of the content comes through in the $content variable of the theme. I'd like to have it come through as different variables (so that I can, inside the theme, place certain content in certain areas.) Is there a proper way for doing this?

  • Access 2003 - Embedded ppt slide or Excel Spreadsheet in a form, how do I communicate?

    - by Justin
    So if I was to take a an access form, and embed either an excel spreadsheet into it, or a powerpoint slide/pres, how would I reference it in VBA code? So I know I have to set the libraries, name the frame of the OLE object, and use applicable syntax to whatever I want to do, with whatever I stick in the form, however the only things I have ever done with excel and/or powerpoint is automate the opening of a seperate window/application from access, not within the access form....so I am not sure?? if I said its a new Excel.Application, then set xls = to (the ss in the file, and not some file path of another excel file somewhere)? does that make sense?

  • How do I synchronize access to shared memory in LynxOS/POSIX?

    - by GrahamS
    I am implementing two processes on a LynxOS SE (POSIX conformant) system that will communicate via shared memory. One process will act as a "producer" and the other a "consumer". In a multi-threaded system my approach to this would be to use a mutex and condvar (condition variable) pair, with the consumer waiting on the condvar (with pthread_cond_wait) and the producer signalling it (with pthread_cond_signal) when the shared memory is updated. How do I achieve this in a multi-process, rather than multi-threaded, architecture? Is there a LynxOS/POSIX way to create a condvar/mutex pair that can be used between processes? Or is some other synchronization mechanism more appropriate in this scenario?

  • Distribute EXE without config file (Webservice in WinForm)

    - by Marc vB
    I have created a WinForm app (VB.NET 2008) that references to a webservice which was added via "Add Service Reference". The app works ok. Question is about distribution of the app. It looks like I need to install the app's config file with the EXE, however I don't want that because the config files shows the actual url of the web service which is not whatt I want. So, is it possible to use a webservice in a WinForm app and only have to install the resulting EXE?

  • DataBinding a DropDownList in ASP.NET MVC 2

    - by Daniel Coffman
    I'm extremely frustrated trying to switch to MVC after a couple years of webforms development. Here's my extremely simple problem that I can't manage to solve: I have a list of States in a table called StateProvince. I have a DropDownList. I want the DropDownList to display all of the States in the StateProvince table and post the selected state back on HTTP PUT. This is what I'm doing: <%: Html.DropDownListFor(model = model.StateProvinceId, new SelectList(Model.StateProvinces, "StateProvinceId", "Name") )% I'm getting an Object reference not set to an instance of an object. Why? How can I make this work? Keep it simple, I know nothing about MVC.

  • Change a subform's recordsource from another subform in Access

    - by Dkellygb
    I am using MS Access 2003 and I have a form with two subforms (subform1 and subform2) which are not nested. They both display tabular data on them so they cannot be nested. I would like to change the recordsource on subform2 based on a value in the current record on subform1. I have tried to put the code in the oncurrent event of subform1 but I cannot seem to refer to the recordsource in subform2 from subform1. From subform1 I have tried me.parent!subform2.form.recordsource but I get a runtime error ‘2455’ You have entered an expression that has an invalid reference to the property form/report. Any ideas?

  • Select dynamic string has a different value when referenced in Where clause

    - by David
    I dynamically select a string built using another string. So, if string1='David Banner', then MyDynamicString should be 'DBanne' Select ... , Left( left((select top 1 strval from dbo.SPLIT(string1,' ')) //first word ,1) //first character + (select top 1 strval from dbo.SPLIT(string1,' ') //second word where strval not in (select top 1 strval from dbo.SPLIT(string1,' '))) ,6) //1st character of 1st word, followed by up to 5 characters of second word [MyDynamicString] ,... From table1 Join table2 on table1pkey=table2fkey Where MyDynamicString <> table2.someotherfield I know table2.someotherfield is not equal to the dynamic string. However, when I replace MyDynamicString in the Where clause with the full left(left(etc.. function, it works as expected. Can I not reference this string later in the query? Do I have to build it using the left(left(etc.. function each time in the where clause?
