Hello everyone, I'm rather new to MySQL so I've a question in a basic thing that is that the way I guess a procedure should be defined is giving an error in the DECLARE _valorOld VARCHAR(100); about an unexpected if and even an unexpected end even if I eliminate the if section. The code is the...

I suppose it's a windows cmd command or maybe it's a system call. I'm searching for the command that allows to cancel the movement/copy on a file (what happens if you press the cancel button on the windows dialog box while copying/moving that file). Greetings.

I'd like to know if there's a way to limit the number of times you can input a password to open an access database. I mean you get your textbox for inputting your password and if you fail it, for example, three times, you get a message "the database has been blocked for an hour" and you cannot...

I have a file mod_foo.c in the folder foo in the bin directory of Apache, this file together with its components has been created with ./apxs-g-n foo. The process I have seen that it is necessary to generate it is: ./apxs-c foo/mod_foo.c gcc-fpic-DSHARED_MODULE -I/usr/local/apache/include-c...

I'm sure this is a truly simple thing to do but I'm getting a serious headache with it. I prefer being told the whole process to do it, until now I've done this way: a)I have my Apache source on /usr/src/http-2.0.63 I have inputted the following commands: ./configure -prefix=/usr/local/apache...

This may look as a very lame question, but I mean, if I create a database with MySQL it seems to be nowhere. In fact I've searched the hard disk using the name I've given to the database and nothing appears. To make my application work on another computer I could save the database info into a...

I want to declare the following thing in an XSD file: Let's suppose we have a <field></field> item. This field can choose between three different types of attributes, but can just have one of them or none. I mean: <field name_attribute="value"> <field name_attribute2="value"> <field...

Using the following code: xslt.Transform(archxml, xslArg, XmlWriter.Create(archhtml) xslt.TemporaryFiles.KeepFiles() = True archhtml keeps occupied by, I suppose the Transform method, the method KeepFiles doesn't also work into freeing the file. I could work around this problem by using a...

I'm trying to build an user-made exception, I have the following code: class CalcError extends Exception { function __construct($message) { parent::Exception($message); } } try { $i=2; if ($i==1)...

Anyone knows how is this function used? It's supposed to create an identical copy of an existing and it's also supposed that the function doesn't have to be declared on it's corresponding class. But in real I do the following thing and it doesn't work: $first=new Prueba2("9","2","3","4")...

Let's suppose I have an application with several formularies, before submitting the formulary the user can check what he has introduced, all non-sensible information in those formularies that was given before by the user must be filled automatically. I've tried doing it this way: <?php if...

This is not really a PHP question but it's related so I think it's worth putting on here. Also I believe anyone that has wanted to test this function or PHPMailer has fallen into the same situation. It would also be ok if someone knows an online SMTP server to practice but I suppose that's...

¿Why doesn't XInclude add the content of the file it refers to the master file? I have those two xml files: master.xml <?xml version="1.0" encoding="UTF-16"?> <?xml-stylesheet href="master.xsl" type="text/xsl"?> <a xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"...

¿How can this process be done? I believe the following code should work nicely: XML document <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE ecosistemas SYSTEM "C:Documents and SettingsUsuarioEscritorioPruebas XMLsimplexlink.dtd"> <?xml-stylesheet href="simplelink.xsl" type="text/xsl"?>...
