• Turning a spreadsheet into array and loop and call a function

  - by Anders

  This is related to generate groups in BuddyPress. I have a spreadsheet with (in this case) a group name, group description and slug. I need to grab the information from the file, turn it into an array, then loop through it and call groups_create_group() every time. I can find that function in bp-groups.php (http://www.nomorepasting.com/getpaste.php?pasteid=35217). It tells me all the parameters you need to fill in. I'm quite new to this and looking for how I can do this. Do you know how I can grab this information and turn it into an array? An loop it through and call groups_create_group() every time?

• Programatticaly grabing text from a web page that is dynamically generated.

  - by bstullkid

  There is a website I am trying to pull information from in perl, however the section of the page I need is being generated using javascript so all you see in the source is <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it!

• MySQL, return only rows where there are duplicates among two columns.

  - by Richard Waite

  I have a table in MySQL of contact information ; first name, last name, address, etc. I would like to run a query on this table that will return only rows with first and last name combinations which appear in the table more than once. I do not want to group the "duplicates" (which may only be duplicates of the first and last name, but not other information like address or birthdate) - I want to return all the "duplicate" rows so I can look over the results and determine if they are dupes or not. This seemed like it would be a simple thing to do, but it has not been. Every solution I can find either groups the dupes and gives me a count only (which is not useful for what I need to do with the results) or doesn't work at all. Is this kind of logic even possible in a query ? Should I try and do this in Python or something?

• problem in reading output of dd command using pipe

  - by Ummar

  I am developing an application, in which I want to redirect the output (progress information) of dd command to my C++ program, but it is not actually getting the output, here is the code FILE * progressInfo = popen("gzip -dc backup/backup.img.gz | pv -ptrbe -i 2 -s 2339876653 | dd of=/dev/sdb","r"); if(!progressInfo) { return -1; } char buf[1024]; while(fgets(buff, sizeof(buff),progressInfo)!=NULL) { std::cout << buff << endl; } but the problem is the progress information is not received in buff, and the output is continuously printed on terminal, and above program halts on while(fgets(buff, sizeof(buff),progressInfo)!=NULL), and as soon as the dd operation is completed, the very next line to loop block is executed. if anyone has any idea why the output is not returned to buff, and its continuously retuned on terminal?

• Crystal Reports not included in Visual Studio 2010 – What are the consequences for the introduction

  - by Dirk

  Yesterday I stumbled over the information that Crystal Reports will no longer be included in Visual Studio 2010. Instead – it will be provided as a free download, but with a separate installation and a separate release date. According to the linked information the release of CR will be later than that of VS. My projects depend in parts on CR and I want to shift early to VS 2010. So there are some related questions: Can I use VS 2010 with the older 2008 version of CR? Do I need a workstation with a preinstalled VS 2008 or is the installation of the CR redistribution package sufficient to run that? Are there any experiences with the VS Beta concerning that?

• Connect android to database

  - by danny

  I am doing a school project where we need to create an android application which needs to connect to a database. the application needs to gain and store information for people's profiles on the database. But unfortunatly we are a little bit stuck at this point because there are numerous ways to link the application such as http request through apache or through the SOAP/REST protocol. But it's really hard to find good instructions or tutorials on the problem since I can't really find them. Maybe that's cause i'm probably using the wrong words on google. Unfortunately I have little relevant information. So if anyone can help me with finding relevant links to good online tutorials or howto's than those are very welcome.

• Creating a view linking three different node types with two node references

  - by mikesir87

  I have the following content types: Camp - the top level type Registration Information - contains node reference to Camp called Camp Medical Release Form - contains node reference to registration information called Camper I would like to create a View that takes the nid for the Camp, and pulls out all the fields for the Registration Info and Medical Release Form. I'm having trouble figuring out how to set up the various arguments/relationships. I haven't done something that's referenced more than two types. I know it would be smart/best to just combine the Registration Info and Medical Release Form, since it's a 1:1 mapping, but we can't. So... any help would be appreciated!

• Visually Viewing and Editing a Two-Dimensional Array - VB/C#

  - by Jeffrey Kern

  I've never personally used any of the Data controls within Visual Studio. I need to view and edit a two-dimensional byte array, 16x15 objects. Is there any control capable of editing this information? I've tried to access data with the DataViewGrid, but am not sure how to use it. It would be great to edit this information via rows and columns, like how you can in Excel. Thank you! Times like this I wish I could just use multiple text boxes and assign them each an index value. Oh VB6 how I miss you :P

• Asp.net Page and control Events

  - by andrewWinn

  I have looked all over the web and I can not find the information I am looking for and I was hoping that someone could give me a hand. Specifically, I am looking for a comprehensive list of what events occur in the page and control life cycles and what is "available" in each event. Like when can I get a dropdownlists selected value, when can i databind, when can I get at values in view state and what not. Can anyone point me to a comprehensive list for both page and control life cycles? Or even provide that information for me? Thanks in advance.

• Interviews that include Algorithms and Data Structures

  - by EricFromSouthPark

  I want to start looking for jobs in great companies and I have four years of enterprise corporations development, three years with C#.NET and alomst one year with Ruby On Rails, JS, etc... But when I look up interview questions from Google, Amazon, Fog Creek, DropBox, etc... they are really targeted at students that are coming fresh out of college and still remember what was Dynamic Programming and Dijkstra algorithms ... but I don't! :( It has been a while for me ... If a I need a sort algorithm I would either Google it or there already is a library and method that does it for me. So what should I do? Do they realize that this guy is not coming from college and will ask more general questions about software architecture or nop! I should go back find my old Data structures book from the storage and read them? In that case wht books and language do you recommend to hone my skills?

• Why is Postgres doing a Hash in this query?

  - by Claudiu

  I have two tables: A and P. I want to get information out of all rows in A whose id is in a temporary table I created, tmp_ids. However, there is additional information about A in the P table, foo, and I want to get this info as well. I have the following query: SELECT A.H_id AS hid, A.id AS aid, P.foo, A.pos, A.size FROM tmp_ids, P, A WHERE tmp_ids.id = A.H_id AND P.id = A.P_id I noticed it going slowly, and when I asked Postgres to explain, I noticed that it combines tmp_ids with an index on A I created for H_id with a nested loop. However, it hashes all of P before doing a Hash join with the result of the first merge. P is quite large and I think this is what's taking all the time. Why would it create a hash there? P.id is P's primary key, and A.P_id has an index of its own.

• How to enforce a site-wide license?

  - by Roy Tang

  We have a small .Net program that we sell with individual licenses. The individual licenses are enforced by registering a key file that is generated using information from the machine used to install the program (MAC address, etc.) Now, we have a customer request for a site-wide license, such that they can deploy to as many machines on their site as possible. From the technical POV I'm not sure what are the usual approaches for this; our old approach won't work since we can't map the license to any machine-specific information. Any suggestions? A few more details: the program is a client-side program that includes an Office Add-In the machines to be installed on may or may not have internet access we aren't restricted to .Net-only approaches, I'm just looking for a general idea of how this sort of thing is usually handled

• Free Tool(s) / Tips to assist me in filling out forms on Win7?

  - by MedicineMan

  I am doing some web development on some long forms. There are many fields for me to fill out to get through the form. Instead of typing out the same things every time (contact information, address, business information) I'm hoping there is some tool out there / combination of tools that will assist me in filling this out. Requirements: I am doing development / testing in FF, IE, and Chrome on a Win 7 system, so the tool would leverage one of those platforms. Oh yeah, one more thing: It's got to be free and lightweight, otherwise, I'd rather just type out responses to the form fields.

• How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

  - by shaz

  I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.

• Problem with variable argument function in C++

  - by Freezerburn

  I'm trying to create a variable length function (obviously, heh) in C++, and what I have right now works, but only for the first argument. If someone could please let me know how to get this working with all the arguments that are passed, I would really appreciate it. Code: void udStaticObject::accept( udObjectVisitor *visitor, ... ) { va_list marker; udObjectVisitor *i = visitor; va_start( marker, visitor ); while( 1 ) { i->visit_staticObject( this ); //the if here will always go to the break immediately, allowing only //one argument to be used if( ( i = va_arg( marker, udObjectVisitor* ) ) ) break; } va_end( marker ); } Based on my past posts, and any help posts I make in general, there is probably some information that I did not provide that you will need to know to help. I apologize in advance if I forgot anything, and please let me know what you need to know so I can provide the information.

• Connecting two DialogBoxes in GWT

  - by Apophenia Overload

  In my GWT project, I'm trying to get it so two DialogBoxes can pass information between each other. One of them holds a MapWidget, and when a button is pressed in the other DialogBox, the position information is received from that other DialogBox's MapWidget. Does anyone have any tips for how I should coordinate between having two different DialogBoxes show up? Should I wrap the code for the two in a Composite? Furthermore, is there an example anywhere of dealing with two DialogBoxes at once in GWT? For example, if I click outside of the two boxes, both should be dismissed. I'm wondering if there's a way to keep both of them in focus at once, so I can switch between the two without causing either to disappear.

• VBScript Issue Help Required.

  - by MalsiaPro

  I need a script that can run and pull information from any drive on a Windows operating system (Windows Server 2003), listing all files and folders which contain the following fields: The server is quite big and is within our domain. The required information is: Full file path (e.g. C:\Documents and Settings\user\My Documents\testPage.doc) File type (e.g. word document, spreadsheet, database etc) Size When Created When last modified When last accessed Also the script will need to convert that data to a CSV file, which later on I can modify and process in Excel. I can imagine that this data will be huge but I still need it. I am logged in as an administrator on the server and the script will need to also process protected files. As in previous posts I have read that the script will stop if such files are processed. I need to make sure that not a single file is skipped. Please note I have asked this question before but still have not got a working script. This is the script I got so far, file Test.vbs: Set objFS=CreateObject("Scripting.FileSystemObject") WScript.Echo Chr(34) & "Full Path" &_ Chr(34) & "," & Chr(34) & "File Size" &_ Chr(34) & "," & Chr(34) & "File Date modified" &_ Chr(34) & "," & Chr(34) & "File Date Created" &_ Chr(34) & "," & Chr(34) & "File Date Accessed" & Chr(34) Set objArgs = WScript.Arguments strFolder = objArgs(0) Set objFolder = objFS.GetFolder(strFolder) Go (objFolder) Sub Go(objDIR) If objDIR <> "\System Volume Information" Then For Each eFolder in objDIR.SubFolders Go eFolder Next End If For Each strFile In objDIR.Files WScript.Echo Chr(34) & strFile.Path & Chr(34) & "," &_ Chr(34) & strFile.Size & Chr(34) & "," &_ Chr(34) & strFile.DateLastModified & Chr(34) & "," &_ Chr(34) & strFile.DateCreated & Chr(34) & "," &_ Chr(34) & strFile.DateLastAccessed & Chr(34) Next End Sub I am currently using the command-line to run it: c:\test> cscript //nologo Test.vbs "c:\" > "C:\test\Output.csv" The script is not working. I don't know why.

• Approach to data wrapping

  - by Mikhail

  I'm developing in PHP and MySQL. The information about the currently logged in user is stored in many different tables. The information that I need on each page, I preload. However if something is needed from a rarely accessed table - then I do $newdata = $db->Query('SELECT * FROM rare_table WHERE user_id='.$user->id); I would like to simplify the above to a point where I don't have to specify that the query should be limited to this particular user. An ideal function call would be: $newdata = $user->Query('SELECT * FROM rare_table'); Obviously I'd have to parse the SQL and add a WHERE clause. Or add to the already existing clause. Questions: are there tools to do this? How can I develop this? Is this even a good idea?

• Webservice for uploading data: security considerations

  - by Philip Daubmeier

  Hi everyone! Im not sure about what authentification method I should use for my webservice. I've searched on SO, and found nothing that helped me. Preliminary Im building an application that uploads data from a local database to a server (running my webservice), where all records are merged and stored in a central database. I am currently binary serializing a DataTable, that holds a small fragment of the local database, where all uninteresting stuff is already filtered out. The byte[] (serialized DataTable), together with the userid and a hash of the users password is then uploaded to the webservice via SOAP. The application together with the webservice already work exactly like intended. The Problem The issue I am thinking about is now: What is if someone just sniffs the network traffic, 'steals' the users id and password hash to send his own SOAP message with modified data that corrupts my database? Options The approaches to solving that problem, I already thought of, are: Using ssl + certificates for establishing the connection: I dont really want to use ssl, I would prefer a simpler solution. After all, every information that is transfered to the webservice can be seen on the website later on. What I want to say is: there is no secret/financial/business-critical information, that has to be hidden. I think ssl would be sort of an overkill for that task. Encrypting the byte[]: I think that would be a performance killer, considering that the goal of the excercise was simply to authenticate the user. Hashing the users password together with the data: I kind of like the idea: Creating a checksum from the data, concatenating that checksum with the password-hash and hashing this whole thing again. That would assure the data was sent from this specific user, and the data wasnt modified. The actual question So, what do you think is the best approach in terms of meeting the following requirements? Rather simple solution (As it doesnt have to be super secure; no secret/business-critical information transfered) Easily implementable retrospectively (Dont want to write it all again :) ) Doesnt impact to much on performance What do you think of my prefered solution, the last one in the list above? Is there any alternative solution I didnt mention, that would fit better? You dont have to answer every question in detail. Just push me in the right direction. I very much appreciate every well-grounded opinion. Thanks in advance!
