  • .NET: will Random.Random operate differently inside a static method

    - by Craig Johnston
    I am having difficulty with the following code which is inside a static method of a non-static class. int iRand; int rand; rand = new Random((int)DateTime.Now.Ticks); iRand = rand.Next(50000); The iRand number, along with some other values, are being inserted into a new row of an Access MDB table via OLEDB. The iRand number is being inserted into a field that is part of the primary key, and the insert attempt is throwing the following exception even though the iRand number is supposed to be random: System.Data.OleDb.OleDbException: The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again. Could the fact the method is static be making the iRand number stay the same, for some reason?

  • Bounce Email handling with PHP??

    - by mcfadder_09
    I am really new to this (not new to php). Here is my scenario: I have 2 emails accounts. [email protected] and [email protected]. I want to send email to all my users with [email protected] but then "reply to" [email protected] (until here, my php script can handle it). When, the email cant be sent, it sent to [email protected], the error message could be 553 (non existent email ...) etc. My question is: How do I direct all those bounce emails (couldn't sent emails) to [email protected] through a handling script to check for the bounce error codes? What programming language should I be for the "handling script"? What would the "handling script" looks like? Can give a sample? OR:(Big Question) What are the procedures I should follow to handle the bounce email ??

  • Mutex names - best practice?

    - by Argalatyr
    Related to this question, what is the best practice for naming a mutex? I realize this may vary with OS and even with version (esp for Windows), so please specify platform in answering. My interest is in Win XP and Vista. EDIT: I am motivated by curiousity, because in Rob Kennedy's comment under his (excellent) Answer to the above-linked Question, he implied that the choice of mutex name is non-trivial and should be the subject of a separate question. EDIT2: The referenced question's goal was to ensure only a single instance of an app is running.

  • How can I disable Ctrl+A (select all) using jquery in a browser?

    - by Keltex
    I'm trying to prevent information to be copied from a page (for non-technical users of course). I know how to disable selecting text using the mouse. The following jquery code works: $(function(){ $.extend($.fn.disableTextSelect = function() { return this.each(function(){ if($.browser.mozilla){//Firefox $(this).css('MozUserSelect','none'); }else if($.browser.msie){//IE $(this).bind('selectstart',function(){return false;}); }else{//Opera, etc. $(this).mousedown(function(){return false;}); }); }); $('.noSelect').disableTextSelect(); }); But users can still use Ctrl+A to select the entire page. Any workarounds for this?

  • Wordpress auto-generated "canonical" links - how to add a custom URL parameter?

    - by kiko
    Hello - Does anyone know how to modify the Wordpress canonical links to add a custom URL parameter? I have a Wordpress site with a page that queries a separate (non-Wordpress) database. I passed the URL parameter "pubID" to display individual books and it is working OK. Example: http://www.uglyducklingpresse.org/catalog/browse/item/?pubID=63 But the individual book pages are not showing up properly in Google - the ?pubID parameter is stripped out. I think maybe this is because all the item pages have the same auto-generated "canonical" URL link tag in the source - one with the "pubID" parameter stripped out. Example: link rel='canonical' href='http://www.uglyducklingpresse.org/catalog/browse/item/' Is there a way to perhaps edit .htaccess to add a custom URL parameter to Wordpress, so that the parameter is not stripped out by permalinks and the "canonical" links? Or maybe there's another solution ... Thank you for any ideas!

  • Java .doc generation

    - by bozo
    Hi, anyone knows an easy method to generate mail merge .doc file from Java? So, I want to create a Word (95/97) document in Word, put some simple placeholders in it (only single value, no iterators and other advanced tags) like the ones used with mailmerge option, and then at runtime replace those placeholders with values from Java. One option is to use Jasperreports, but this would require that I create exact replica of non-trivial Word document in Jasper format, which is not easy and is hard to change later. Is there some method of filling placeholders in Word from Java, which does not require low-level document alteration with positioning and others low-level .doc tags from code, but something like this: docPreparer.fillPlaceholder('placeholder1', 'my real value from runtime'); Some CRMs do this via ActiveX control for internet explorer, and it works great (they use Word's mailmerge) but I need an all-Java solution. Ideas? Thanks, Bozo

  • ASP.NET MVC SSL POST Error

    - by RyanFetz
    I have a Logon page in a MVC (1.0) application that I am securing with SSL, I have an attribute that inspects the request for the page and redirects to a https uri when it is requested with http. This all works, however when I post the form content i get the following error: The parameters dictionary contains a null entry for parameter 'rememberMe' of non-nullable type 'System.Boolean' for method 'System.Web.Mvc.ActionResult LogOn(System.String, System.String, Boolean, System.String)' in 'DAC.US.Web.Portal.Controllers.AccountController'. To make a parameter optional its type should be either a reference type or a Nullable type. Parameter name: parameters here is the controller code... // // GET: /Account/LogOn [RequiresSSL] public ActionResult LogOn(string ReturnUrl) { if (TempData["Message"] != null) ViewData["Message"] = TempData["Message"]; TempData["Message"] = null; ViewData["ReturnUrl"] = ReturnUrl ?? "/Home"; return View(); } Again, the RequireSSL Attribute works, but the POST from that SSL uri does not. What is not working?

  • how to invoke onclick function in html from vb.net or C#

    - by vbNewbie
    I am trying to invoke the onclick function in an html page that displays content. I am using the httpwebreqest control and not a browser control. I have traced the function and tried to find the link it calls but looking at the code below I tried inserting the link into the browser with the main url but it does not work. <div style="position:relative;" id="column_container"> <a href="#" onclick=" if (! loading_next_page) { loading_next_page = true; $('loading_recs_spinner').style.visibility = 'visible'; **new Ajax.Request('/recommendations?directory=non-profit&page=**' + next_page, { onComplete: function(transport) { if (200 == transport.status){ $('column_container').insert({ bottom: transport.responseText }); loading_next_page = false; $('loading_recs_spinner').style.visibility = 'hidden'; next_page += 1; if (transport.responseText.blank()) $('show_more_recs').hide(); } } }); } return false; Any ideas would be deeply appreciated.

  • SQL Server: Can INFORMATION_SCHEMA Tell Me When a SQL Object Was Created?

    - by Jim G.
    Given: I added a non-nullable foreign key to a table. I settled on a way to populate the foreign key with default values. I checked in both changes to a re-runnable DB creation script. Other developers ran this script, and now they have the foreign key populated with default values on their developer machines. A few days later however... I changed my mind. Now I'd like to populate the foreign key's default values differently. My Question: Can SQL Server or INFORMATION_SCHEMA tell me when SQL objects were created? Ideally, I'd like to drop and re-add the foreign key if it was created before a certain date/time. Any help or alternative strategies would be greatly appreciated. Obviously, I'd like to avoid going to each developer's cube, asking them to drop the foreign key manually.

  • NO-SQL reliable for small bussines app?

    - by mamcx
    I'm deciding between go for a NON-SQL engine or a regular SQL one for a document managment system for small bussines. I have experience with firebird/sql server and found a good track of reliability (specially with firebird). This market is full of crappy "servers" (clon-made PC, the mayority), cheap harddisk, rarely use of RAID or anything like that, some are in locations where a power-off is normal, some not have a UPS, etc... (I will include off-site auto-backup to external servers, but that no change the internal setup). (I know about end-user education about such proper setups, but is stupid depend on that, so stick to te point) From the desing point of view, a schema-less database is the way to go for my system, but, I worry if any of the actual solutions (MongoDb, Tokyo Cabinet, etc) are like firebird and survice crash, malfunctions & abuse so data corruption is very rare. The plan is store the office documents there & provide a central repository.

  • Unbuffered subprocess output (last line missing)

    - by plok
    I must be overlooking something terribly obvious. I need to execute a C program, display its output in real time and finally parse its last line, which should be straightforward as the last line printed is always the same. process = subprocess.Popen(args, shell = True, stdout = subprocess.PIPE, stderr = subprocess.PIPE) # None indicates that the process hasn't terminated yet. while process.poll() is None: # Always save the last non-emtpy line that was output by the child # process, as it will write an empty line when closing its stdout. out = process.stdout.readline() if out: last_non_empty_line = out if verbose: sys.stdout.write(out) sys.stdout.flush() # Parse 'out' here... Once in a while, however, the last line is not printed. The default value for Popens's bufsize is 0, so it is supposed to be unbuffered. I have also tried, to no avail, adding fflush(stdout) to the C code just before exiting, but it seems that there is absolutely no need to flush a stream before exiting a program. Ideas anyone?

  • Obtaining C++ Code Coverage

    - by anon
    I'm on Linux. My code is written in C++. My program is non-interactive; it runs as "./prog input-file", processes the file, and exits. I have various unit tests "input-file0, input-file1, input-file2, ..." For designing new unit tests, I want to know what lines of code existing tests do not cover. Question: Given that I control how "prog" is compiled/run; how can I get list of the lines of code that "./prog input-file" does not hit? Thanks!

  • Limitations in running Ruby/Rails on windows

    - by johnc
    In the installation documentation to RoR it mentions that there are many limitations to running Ruby on Rails on Windows, and in some cases, whole libraries do not work. How bad are these limitations, should I always default to Linux to code / run RoR, and is Iron Ruby expected to fix these limitations or are they core to the OS itself? EDIT Thanks for the answer around installation and running on Linux, but I am really trying to understand the limitations in functionality as referenced in the installation documentation, and non-working libraries - I am trying to find a link to the comment, but it was referenced in an installation read me when I installed the msi package I think

  • python: using __import__ to import a module which in turn generates an ImportError

    - by bbb
    Hi there, I have a funny problem I'd like to ask you guys ('n gals) about. I'm importing some module A that is importing some non-existent module B. Of course this will result in an ImportError. This is what A.py looks like import B Now let's import A >>> import A Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/tmp/importtest/A.py", line 1, in <module> import B ImportError: No module named B Alright, on to the problem. How can I know if this ImportError results from importing A or from some corrupt import inside A without looking at the error's string representation. The difference is that either A is not there or does have incorrect import statements. Hope you can help me out... Cheers bb

  • Is it professional to have funny looking logging messages

    - by JCH
    Hi, Recently I have joined a new project team where in the java application logs have logged messages in a non-formal way[can't think of suitable word]. here how they look :-) <message> for info messages :-| <message> for warn :-( <message> for error besides there's also ASCII art drawing , different one for each log when that particular service starts up or is killed .And there many more styles for certain application events. iam not sure if it has any significant overhead on the application or not. I would like to ask you folks if you come across such unique styles of logging messages or do you also practice any styles.what is your opinion about it. BR /jon

  • Rebuilding lazily-built attribute when an underlying attribute changes in Moose

    - by friedo
    I've got a Moose class with a lazy_build attribute. The value of that attribute is a function of another (non-lazy) attribute. Suppose somebody instantiates the class with a value of 42 for the required attribute. Then they request the lazy attribute, which is calculated as a function of 42. Then, they have the nerve to change the first attribute! The lazy one has already been built, so the builder will not get called again, and the lazy attribute is now out-of-date. I have a solution now where I maintain a "dirty" flag on the required attribute, and an accessor on the lazy one checks the dirty flag and rebuilds it if needed. However, this seems like a lot of work. Is there a way to handle this within Moose, e.g. using traits?

  • How to capture any key in X?

    - by cz-david
    Hi, I am building an application for which I need to periodically get information about users keyboard. It is going to be user idle detection application. I have a fairly simple solution to periodically check if the mouse has been moved. But I can't figure any reasonable non root way to detect if the keyboard has been pressed. I was thinking about registering a hook every timer timeout and on any key press to unregister it. So if there is no key press for a long time then my program will know if the user is idle. Anyway, I couldn't find any global hooks for any key, including modifiers. Is there an easy way to do this? Or would someone have a better way to detect keyboard idleness? Thanks, David Polák

  • How can I make a case-insensitive regexp match for Russian letters?

    I have list of catalog paths and need to filter out some of them. My match pattern is in a non-Unicode encoding. I tried the following: require 5.004; use POSIX qw(locale_h); my $old_locale = setlocale(LC_ALL); setlocale(LC_ALL, "ru_RU.cp1251"); @{$data -> {doc_folder_rights}} = grep { # catalog path pattern in $_REQUEST{q} $_->{doc_folder} =~/$_REQUEST{q}/i; } @{$data -> {doc_folder_rights}}; setlocale(LC_ALL, $old_locale); What I need is case-insensitive regexp pattern matching when pattern contains russsian letters.

    our client needs to shortcuts to particular pages We need to redirect non existent urls like http://site.com/promotion1 to the actual URL similar to http://site.com/promotions/promotion1/tabid/799/language/en-AU/Default.aspx ...

In the mean time they still submitting requests to us to create redirects for them. if there's no cost involved then i wont have to wait for them to get back to me. so I'm looking for a Quick and free way to enable the clients to set these up on this own.

  • Using ed to manipulate files matched by find

    - by TheOsp
    Following the bash-hackers wiki's recommendation, I want to edit files using ed. In particular I want to do the following with ed instead of sed: find . -type f -exec sed -i -e 's/a/b/g' {} \; I see that ed doesn't have opt like sed's -e, so as far as I know, pipes and io redirections are the only way to work with it non-interactively. So, using ed from a bash script to do the same as the above sed command would look like: ed file_name <<<$'g/a/s//b/g\nw' Or echo $'g/a/s//b/g\nw' | ed file_name But as far as I know it is impossible to involve pipes or io redirections within find's -exec. Do I miss something? or is the only way to overcome this is to use loops? for file in $(find . -type f -print); do ed $file <<<$'g/a/s//b/g\nw'; done;

  • Problem with javascript in firefox when moving google ads

    - by thomas woelfer
    hi. i have a website with google ads on it. i would like to make it load faster. thus i moved all the google scripts to the bottom of the page. i also have a placeholder at the location where the ad(s) should be displayed and other divs that (initially) get the ads. finally (in window.onload) i'm moving the ads that have just be fetched from google to their target locations. (a simple example page is here: http://www.nickles.de/temp/ads.html ) this works in ie, but it doesn't work in ff. (that is, in firefox, non-text ads show up fine, while text-ads don't. [or at least, not in a reliable way.]) any ideas what would be causing this? Thanks! -thomas woelfer

  • How Moles Isolation framework is implemented?

    - by Buu Nguyen
    Moles is an isolation framework created by Microsoft. A cool feature of Moles is that it can "mock" static/non-virtual methods and sealed classes (which is not possible with frameworks like Moq). Below is the quick demonstration of what Moles can do: Assert.AreNotEqual(new DateTime(2012, 1, 1), DateTime.Now); // MDateTime is part of Moles; the below will "override" DateTime.Now's behavior MDateTime.NowGet = () => new DateTime(2012, 1, 1); Assert.AreEqual(new DateTime(2012, 1, 1), DateTime.Now); Seems like Moles is able to modify the CIL body of things like DateTime.Now at runtime. Since Moles isn't open-source, I'm curious to know which mechanism Moles uses in order to modify methods' CIL at runtime. Can anyone shed any light?
