• Batch backup a harddrive without modifying access times C#

  - by johnathan-doena

  I'm trying to write a simple program that will backup my flash drive. I want it to work automatically and silently in the background, and I also want it to be as quick as possible. The thing is, resetting all the access times is useless to me, and something I want to avoid. I know I can read the access times and set them back, but I bet it will fail one day in the future. It would be much simpler to read the files without ever changing it. Also, what is the fastest way to do this? What differences would there be between, say, a flash drive and an external hard drive. I am writing this in C#, as it is the simplest way to do it and it will probably last more generations of Windows..

• why message box is always hidden behind main dialog and cannot be shown on the top

  - by Cougar_usa

  I am using MFC to write a GUI application. I chose dialog-based application, and put picture control, edit box and buttons on it. When the picture control is mapped to the class derived from CWnd using DDX_Control, all the message boxes (including default system message box pop up when you enter invalid input in the edit box) are hidden behind main dialog until you use "alt + tab" to bring them to front. If I map the picture control to the default CStatic class, the above problem disappeared. Do anyone has some hints to solve this problem? Thank you in advance for any help.

• How can I create a simple message box in Python?

  - by Carson Myers

  I'm looking for the same effect as alert() in JavaScript. I wrote a simple web-based interpreter this afternoon using Twisted.web. You basically submit a block of Python code through a form, and the client comes and grabs it and executes it. I want to be able to make a simple popup message, without having to re-write a whole bunch of boilerplate wxPython or TkInter code every time (since the code gets submitted through a form and then disappears). I've tried tkMessageBox: import tkMessageBox tkMessageBox.showinfo(title="Greetings", message="Hello World!") but this opens another window in the background with a tk icon. I don't want this. I was looking for some simple wxPython code but it always required setting up a class and entering an app loop etc. Is there no simple, catch-free way of making a message box in Python?

• xpath help substring expression

  - by NA

  Hi i have a document from which i am trying to extract a date. But the problem is within the node along with the date their is some text too. Something like <div class="postHeader"> Posted on July 20, 2009 9:22 PM PDT </div> From this tag i just want the date item not the Posted on text. something like ./xhtml:div[@class = 'postHeader'] is getting everything. and to be precise, the document i have is basically a nodelist of this elements for eg i will get 10 nodes of these elements with different date values but to be worse the problem is sometime inside these tags some random other tags also pops us like anchors etc. Can i write a universal expath which will just get the date out of the div tag?

• Tmp issues with java service on windows 2008 service

  - by Mans

  Hello! I am having a rather nasty problem with windows 2008 server. We have a java application that is running as a service using the local services user. The problem is this user does not have access to read/write to the specified java tmp directory (specified by the system). This means that every time the application tries to create a tmp file an IOException is thrown. Is there any way to make a java application that need access to the tmp directory run as a service without: Creating a new user specifically for the purspose Specifying a new tmp directory (which you will have to clean up yourself)

• Express highest floating point quantity that is less than 1

  - by edA-qa mort-ora-y

  I was doing some rounding calculations and happened upon a question. How can I express the highest quantity less than 1 for a given floating point type? That is, how I write/represent value x such that x < 1, x + y >= 1 for any y > 0. In fractions this would be x = (q-1)/q where q is the precision of the type. For example, if you are counting in 1/999 increments then x = 998/999. For a given type (float, double, long double), how could one express the value x in code? I also wonder if such a value actually exists for all values of y. That is, as y's exponent gets smaller perhaps the relation doesn't hold anymore. So an answer with some range restriction on y is also acceptable. (The value of x I want still does exist, the relationship may just not properly express it.)

• extension method phone format with country code as parameter

  - by frenchie

  Hi, I'm writing an extension method called ToPhoneFormat that formats a string of digits to phone numbers. Is it possible to add a parameter to the method that would enable me to call it like this: MyPhoneString.ToPhoneFormat(international code) That way, I could write MyPhoneString.ToPhoneFormat(1); to format a US phone number and MyPhoneString.ToPhoneFormat(33) to format a French phone number. I already wrote the method that does the formatting but I'm wondering how to build the constructor so that it works with a parameter when I'm calling it. Thanks.

• Django: way to test what class a generic relation content_object is?

  - by bitbutter

  In my project I have a class, NewsItem. Instances of NewsItem act like a wrapper. They can be associated with either an ArtWork instance, or an Announcement instance. Here's how the NewsItem model looks: class NewsItem(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') date = models.DateTimeField(default=datetime.datetime.now,) class Meta: ordering = ('-date',) def __unicode__(self): return (self.title()) In a template I'm dealing with a NewsItem instance, and would like to output a certain bunch of html it it's 'wrapping' an Artwork instance, and a different bunch of html if it's wrapping an Announcement instance. Could someone explain how I can write a conditional to test for this? My first naive try looked like this: {% if news_item.content_object.type=='Artwork' %}do this{% else %}do that{% endif %}

• Drag and drop + custom drawing in Android

  - by Rich

  I am working on something that needed custom drag-and-drop functionality, so I have been subclassing View, doing a bunch of math in response to touch events, and then rendering everything manually through code on the canvas in onDraw. Now, the more functionality I add, the more the code is growing out of control and I find myself writing a ton more code than I would expect to write in a high level environment like Android. Is this how it's done, or am I missing something? If I'm not doing anything fancy in the UI, the framework handles the majority of my interactions. Built-in controls handle the touches and drags, and my code is pretty much limited to business logic and data. Is there a way to leverage the power of some of the UI controls and things like animations while also doing some of it manually in the onDraw canvas? Is there an accepted standard of when to use one or the other (if indeed the two approaches can be mixed)?

• How to obtain specific Excel object library without the corresponding Office version installed.

  - by james-h-l

  I am developing a Excel automation app that read and write to Excel spreadsheet. I have Office 2007 installed on my machine. I therefore can reference the Excel 12.0 Object Library and the Excel 5.0 Object Library. I don't want to use Excel 5.0 because it's really quite old and poorly documented. Therefore I'm referencing Excel 12.0. However the target machine have Office 2003 installed and therefore only have Excel 11.0. So when I compile my program it crashes on the target machine since the referenced library are different. I was wondering is there a way I could obtain the Excel 11.0 without installing Office 03? I tried to find answers from msdn and microsoft support page but couldn't find anything? This is quite strange since it could also happen in the future where developers has newer editions of Office than clients?

• Best Ruby ORM for Wrapping around Legacy SQL Server Database?

  - by Technocrat

  Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support SQL Server through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in SQL Server. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the SQL Server app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with SQL Server but never to do anything quite like this. Any suggestions?

• windows service

  - by zubin71

  I need to write a windows service which executes an application after a certain amount of time. I have checked out the code in MSDN and found an example in which the System.ServiceProcess.ServiceBase class is sub-classed. I did the following. created a new C# console application copied the code from the MSDN example Run I get the following error The type or namespace name 'ServiceProcess' does not exist in the namespace 'System'(are you missing an assembly reference?) As i had copied the example from MSDN, i have no idea why the code still does not work. This is my first experience writing services and i`d love some guidance. thnkx!

• Problems with noobs putting my GA code into their sites

  - by dclowd9901

  I don't mean for the title to be derogatory, but this is a rather frustrating problem, and I'm looking for a good workaround, given a language barrier involved. I have a site set up for a plugin I wrote, and, rather than use the site's resources to write their own code, I've had people simply rip the code from the samples on the site. Normally, this wouldn't be any issue at all, but they are also taking my Google Analytics instantiation, so my Analytics data is getting very skewed by incorporating visitation data from their websites. I've been able to contact the English-speaking site owners with little issue. The problem lies in the Japanese language sites that are yanking the code. I have no idea how to ask them to take down the analytics portion. Long-term, I'm providing a package that streamlines the learning-to-use process, but in the meantime, what can I do about this language barrier? Is there a way around this problem that I haven't thought of?

• Unlock a file with unlocker from a c# App?

  - by netadictos

  I am trying to unlock a file from a C# program, using unlocker. In my UI, I put a button to unlock the file the app couldn't delete. When the user pushes the button, I want unlocker (the famous app) to be opened. I have read about in the Unlocker web, and there is some explanations about the commandline to use but nothing works. I write the following code but nothing happens: "c:\Program Files\unlocker\unlocker.exe" -L "PATHFORTHEFILE.doc" Nothing happens. I have tried without parameters and with -LU. Any idea? Something more efficient than unlocker to integrate it with software?

• generic function for extracting values from an array with one particular key in PHP

  - by Sabya

  Is it possible in PHP to extract values from an array with a particular key path and return an array of those values? I'll explain with an example: $user = array ( array( id => 1, email =>'[email protected]', project => array ('project_id' => 222, 'project_name' => 'design') ), array( id => 2, email =>'[email protected]', project => array ('project_id' => 333, 'project_name' => 'design') ) ); /** I have to write a function something like: */ $projectIds = extractValuesWithKey($user, array('project', 'project_id')); print_r($projectIds); Output: Array( [0] => 222, [1] => 333 )

• How to deal with 'bad' decision forced on you regarding basic software for your product

  - by raticulin

  Here is my situation, our product used to support several of the major databases. Now management has decided to move all products to MaxDB (aka SapDB previously), and even if we keep supporting some of the previous dbs, all new installations are on MaxDB. I am sure MaxDB is a great db and can support huge SAP installations. But from the point of view of a software developper, its a nightmare. Every time you need to do something not trivial (write an stored procedure, some fancy trigger...) and you google for some info, you get like 0.1% of the hits you would with things like MySql, PostgreSql or MSSql. Mailing lists are nearly non existant. SAP does support it commercially but it is not clear wether we'll buy support. And the decision cannot be rolled back. The product works with MaxDB, but with lots of inefficiency on development and a lot of frustration, is there something one could do?

• vba excel copy subtable from sheet to sheet

  - by user429400

  I realize that this is probably a duplicate, but I've been searching for an hour and I can't to get the syntax right. I have a sheet with several tables. There is at least one empty column and one empty row between one table to the other. I know the start row and start column of each table, and I know that each table has 3 columns. I don't know how many rows it has. I want to write a sub that receives: table start row table start column and copies the table into another sheet (let's say that the destination is sheet2 starting at A1). I know I can do it with a loop, but I suspect there is a better syntax right? (The main issue here is that I need to find the number of rows each table has) Thanks. Li

• Powershell 2.0 - Running scripts for the command line call vs. from the ISE

  - by Gromix

  Hi, After writing deployment scripts from within the ISE, we need our CI server to be able to run them automatically, i.e. from the command line or via a batch file. I have notice some significant differences between the following calls: powershell.exe -File Script.ps1 powershell.exe -Command "& '.\Script.ps1'" powershell.exe .\Script.ps1 Some simple examples: When using -File, errors are handled in the exact same way as the ISE. The other two calls seem to ignore the $ErrorActionPreference variable, and do not catch Write-Error in try/catch blocks. When using pSake: The last 2 calls work perfectly Using the ISE or the -File parameter will fail with the following error: The variable '$script:context' cannot be retrieved because it has not been set Could someone help me understand the implications of each syntax, and why they are behaving differently? I would ideally like to find a syntax that works all the time and behaves like the ISE. Thanks, Romain

• passing values to pages

  - by Indranil Mutsuddy

  Hello friends, What i am trying here is to pass values to other pages. When i include the following code private void Button1_Click(object sender, System.EventArgs e) { // Value sent using HttpResponse Response.Redirect("WebForm5.aspx?Name="+txtName.Text); } if (Request.QueryString["Name"]!= null) Response.write( Request.QueryString["Name"]); everything works fine the name gets displayed. Now if use MemberId instead, though i can see the Id in the Url, but while checking for Null in other page, its true. Whats wrong?? Now I tried the same thing using session i.e. Session["MemberId"] = this.TxtEnterMemberId.Text; if (MemberSex.Equals("M")) Response.Redirect("PatientDetailsMale.aspx",false ); Page_load event of the other page if (Session["MemberId"] != null) mid = Session["MemberId"].ToString(); IT Works..Could u guys explain the behaviour please? P.S. Can anyone give a breif in layman words about SessionId and its usage. Thanking you, Indranil
