  • "Blank SQL" error with phppgadmin

    - by Hoàng Long
    Here is my problem: I export a database A_DB using "export" function of Phppgadmin. The dump file A_dump.sql includes both the database structure and data. Then I try to create another blank database B_DB, and import A_dump.sql into it. Every time I do that, the transaction failed with no error reported: SQL error: In statement: Is there some logs that I can find in phppgadmin that would allow me to investigate this problem? I have tried searching for an hour, but still not find anything.

  • MonoTouch's Soft Debugger don't connect to App on iPhone - why?

    - by smokinharp
    Hi everyone, I'm quite new on MonoTouch, so please forgive me my question in doubt... ;-) I need help with the soft-debugger, because it's not connecting to the App on the device. While with iPhone Simulator everything is working as expected, the following happens when I start debugging against my device: The is uploaded and installed to the device. MonoDevelop comes up with a window saying the following: "Waiting for debugger to connect on 127.0.0.1:10000..." Please start the application on the device" When starting the app on the device, the device vibrates indicating that the debugger is not connected.... In the settings of my App on the iPhone I have set the IP-Adress to my Mac's IP. My iPhone is connected via WIFI to my network. I can ping my Mac from my iPhone and vice versa. In several screenshots where the debugger was obviously working I saw that the debugger came up with the Mac's IP address and not the 127.0.0.1.... Do I have to configure my IP-address somewhere in MonoDevelop? BTW: I'm using the latest version of MonoDevelop - it's 2.4.1 I have tried anything.... re-installing MonoDevelop, cleaning up the project several times, setting up a new project.... nothing... Please, please help....

  • Would there be a market for this idea (cross platform VM for iPhone OS)

    - by Tzury Bar Yochay
    For a long time I wondered if the following idea worth a nickel or just a waste of time and energy. I am willing to start a project which will provide a kind of a VM for all iPxxx apps - so developed once for iPxxx can run on a Macbook, iMac, Linux, Android and windows (desktop and mobile). You get the idea, right? I want to do to the current iPhone SDK, the same as what Mono did to Microsoft .Net and perhaps a more complete set of implementation. I tend to believe that if overnight all apps on appstore become available on the android market as well that would be a mini revolution. Think about running iPad apps on every tablet that will come out to the market in the future. Wouldn't it be fantastic to all the developers, which from now on, can write once and sell everywhere? The main questions which I ask myself repeatedly is: "Is This Legal?" - I mean, say I have done this, would apple's lawyers will start sending me all kinds of nasty emails? I am willing to hear your opinion about this idea as well as if some of you willing and able to join forces and start this open source project.

  • How to trigger the specific controller action using a button?

    - by Eugene
    I'm creating a simple training project. I've implemented a controller method, which deletes an item from the list. The method is looking like this: @Controller @RequestMapping(value = "/topic") public class TopicController { @Autowired private TopicService service; ... @RequestMapping(value = "/deleteComment/{commentId}", method = RequestMethod.POST) public String deleteComment(@PathVariable int commentId, BindingResult result, Model model){ Comment deletedComment = commentService.findCommentByID(commentId); if (deletedComment != null) { commentService.deleteComment(deletedComment); } return "refresh:"; } } This method is called from the button-tag, which is looking in the following way: _form> _button formaction = "../deleteComment/1" formmethod = "post">delete_/button> _/form> Sorry, but in the form tag I've changed all the '<' characters with the '_', because the tag was invisible. In my project the form-tag is looking like a cliuckable button. But there is a serious problem: controller's method is never triggered. How can I trigger it, using a button-tag? P.S. the call is performed from the page with URI http://localhost:8080/simpleblog/topic/details/2 and controller's URI is the http://localhost:8080/simpleblog/topic/deleteComment/2

  • Flattening out a lib directory using jarjar

    - by voodoogiant
    I'm trying to flatten out the lib directory of a project using jarjar, where it will produce a jar file with my main code and all my required libraries inside of it. I can get the project code into the jar, but I need to find a way to get every jar in the './lib/' directory extracted to the base directory of the final output jar. I don't want it flattened in the sense that I still want the package hiearchy preserved. I could manually list every jar file using zipfileset, but I was hoping to do it dynamically. I would also like to include any *.so files flattened into the base directory of the output jar so I can extract them into a temp dir easily without having to search through the jar. For example my lib directory... ./lib/library1.jar ./lib/library2.jar ./lib/foo/library3.jar ./lib/foo/bar.so would look like this when cracked open in the output jar file... /..library1_package_hierarchy../lib1.class /..library1_package_heirarchy../lib2.class ... (and so on) /..library2_package_hierarchy../lib1.class /..library2_package_heirarchy../lib2.class ... (and so on) /..library3_package_hierarchy../lib1.class <-- foo gone /..library3_package_heirarchy../lib2.class <-- foo gone /bar.so <-- foo gone

  • How classes are secure than structures ?

    - by Asad Hanif
    Structure's member are public by default ans class's members are private by default. We can access private data members through a proper channel (using member function). If we have access to member functions we can read/write data in private data member, so how it is secure...we are accessing it and we are changing data too.....

  • Java: I've created a list of word objects to include the name and the frequency, but having trouble

    - by adam08
    Hi Everyone, I'm working on a project which has a dictionary of words and I'm extracting them and adding them to an ArrayList as word objects. I have a class called Word as below. What I'm wondering is how do I access these word objects to update the frequency? As part of this project, I need to only have one unique word, and increase the frequency of that word by the number of occurrences in the dictionary. Word(String word) { this.word = word; this.freq = 0; } public String getWord() { return word; } public int getFreq() { return freq; } public void setFreq() { freq = freq + 1; } This is how I am adding the word objects to the ArrayList...I think it's ok? String pattern = "[^a-zA-Z\\s]"; String strippedString = line.replaceAll(pattern, ""); line = strippedString.toLowerCase(); StringTokenizer st = new StringTokenizer(line); while (st.hasMoreTokens()) { String newWord = st.nextToken(); word.add(new Word(newWord)); count++; }

  • NoSQL vs Relational Coding Styles

    - by Chris Henry
    When building objects that make use of data stored in a RDBMS, it's normally pretty clear what you're getting back, as dictated by the tables and columns being queried. However, when dealing with NoSQL, document-based systems, it's less clear what is being retrieved. What are common methods of keeping track of structure in which data is stored?

  • Can someone answer this for me?

    - by Dcurvez
    okay I am totally stuck. I have been getting some help off and on throughout this project and am anxious to get this problem solved so I can continue on with the rest of this project. I have a gridview that is set to save to a file, and has the option to import into excel. I keep getting an error of this: Invalid cast exception was unhandled. At least one element in the source array could not be cast down to the destination array type. Can anyone tell me in layman easy to understand what this error is speaking of? This is the code I am trying to use: Dim fileName As String = "" Dim dlgSave As New SaveFileDialog dlgSave.Filter = "Text files (*.txt)|*.txt|CSV Files (*.csv)|*.csv" dlgSave.AddExtension = True dlgSave.DefaultExt = "txt" If dlgSave.ShowDialog = Windows.Forms.DialogResult.OK Then fileName = dlgSave.FileName SaveToFile(fileName) End If End Sub Private Sub SaveToFile(ByVal fileName As String) If DataGridView1.RowCount > 0 AndAlso DataGridView1.Rows(0).Cells(0) IsNot Nothing Then Dim stream As New System.IO.FileStream(fileName, IO.FileMode.Append, IO.FileAccess.Write) Dim sw As New System.IO.StreamWriter(stream) For Each row As DataGridViewRow In DataGridView1.Rows Dim arrLine(9) As String Dim line As String **row.Cells.CopyTo(arrLine, 0)** line = arrLine(0) line &= ";" & arrLine(1) line &= ";" & arrLine(2) line &= ";" & arrLine(3) line &= ";" & arrLine(4) line &= ";" & arrLine(5) line &= ";" & arrLine(6) line &= ";" & arrLine(7) line &= ";" & arrLine(8) sw.WriteLine(line) Next sw.Flush() sw.Close() End If I bolded the line where it shows in debug, and I really dont see what all the fuss is about LOL

  • Entity Relationships - Can a weak entity take part in a 'one to many' relationship as the 'one'

    - by jonos
    Hi, With the following entity relationship structure I'm struggling to figure out if the relationship between the LOAN and ITEM is valid? The weak entity of Loan uses a partial key of 'loan_dateLeant' and the primary keys from CUSTOMER and ITEM to form its primary key. However LOAN has a 'one to many' relationship with ITEM as a loan can consist of more than one item. But surely this means that if more than one item is loaned, then the loan record will have two item_id values for part of its primary key?

  • What is the best Networking implementation for my application?

    - by CaptainPhil
    I am in the planning phases of a project for myself, it is to be a single and multi-player card game. I would like to track statistics for each person such as world rankings etc... My problem is I do not know the best approach for the client - server architecture and programming. My original goal was to program everything in C# as I want to get proficient in that language. My original idea was to have a back-end database and a back end server run on some sort of hosting on the internet, however that seems costly for such a small project that may or may not make any money. I have tried looking into cloud services however I am unfamiliar with the technology, and I am not sure I can make them suit my needs, especially since most like Google's cloud wants you to use their coding architecture from what I understand. Finally my last problem is that I would like an architecture that can be used for different languages so that I can port it from PC to IPhone, Xbox etc... So does anyone have any advice on the best architecture and language to do this in? Am I worrying about architecture and back-end costs to much and should just concentrate on getting the game running any which way?

  • CSS to Make 2 Column Content Areas

    - by Joe Majewski
    I'm trying to stray away from using tables to form the layout of my content, and I can think of two alternatives that I'd like to better learn: (1) styling list items to be side-by-side, and (2) using div blocks that float onto the same line. Both of these would have their own uses for what I'm working on. I'm already using div tags to form the entire layout of my three-column template, but what I need to do now is a bit different. In case it helps, my project can be found here. In short, here's my question; how would I style a div so that the width of it is 50% of the width of the area it occupies, rather than 50% of the width of the page? As for my other question, what would be the best approach to styling list items so that they are side-by-side? I'm working on a registration script now, and instead of using a table with "Username" on the left and the input text on the right, I can use two list items. It's late and I've been working on this project of mine for about 8 hours straight now, so I apologize if I'm asking anything confusing. Feel free to ask me any questions about what I'm trying to do. Thanks, friends. :)

  • [boost::filesystem] performance: is it better to read all files once, or use b::fs functions over an

    - by rubenvb
    I'm conflicted between a "read once, use memory+pointers to files" and a "read when necessary" approach. The latter is of course much easier (no additional classes needed to store the whole dir structure), but IMO it is slower? A little clarification: I'm writing a simple build system, that read a project file, checks if all files are present, and runs some compile steps. The file tree is static, so the first option doesn't need to be very dynamic and only needs to be built once every time the program is run. Thanks

  • C# recursive programming with lists

    - by David Torrey
    I am working on a program where each item can hold an array of items (i'm making a menu, which has a tree-like structure) currently i have the items as a list, instead of an array, but I don't feel like I'm using it to its full potential to simplify code. I chose a list over a standard array because the interface (.add, .remove, etc...) makes a lot of sense. I have code to search through the structure and return the path of the name (i.e. Item.subitem.subsubitem.subsubsubitem). Below is my code: public class Item { //public Item[] subitem; <-- Array of Items public List<Item> subitem; // <-- List of Items public Color itemColor = Color.FromArgb(50,50,200); public Rectangle itemSize = new Rectangle(0,0,64,64); public Bitmap itemBitmap = null; public string itemName; public string LocateItem(string searchName) { string tItemName = null; //if the item name matches the search parameter, send it up) if (itemName == searchName) { return itemName; } if (subitem != null) { //spiral down a level foreach (Item tSearchItem in subitem) { tItemName = tSearchItem.LocateItem(searchName); if (tItemName != null) break; //exit for if item was found } } //do name logic (use index numbers) //if LocateItem of the subitems returned nothing and the current item is not a match, return null (not found) if (tItemName == null && itemName != searchName) { return null; } //if it's not the item being searched for and the search item was found, change the string and return it up if (tItemName != null && itemName != searchName) { tItemName.Insert(0, itemName + "."); //insert the parent name on the left --> TopItem.SubItem.SubSubItem.SubSubSubItem return tItemName; } //default not found return null; } } My question is if there is an easier way to do this with lists? I've been going back and forth in my head as to whether I should use lists or just an array. The only reason I have a list is so that I don't have to make code to resize the array each time I add or remove an item.

  • Mercurial "server"

    - by user85116
    I've been using mercurial for a little while, but mainly for my own usage. Now though, I have a project I'm working on where two of us are building the same project, and we will probably be modifiying each other's files. I would like to setup a mercurial repo on a server, make that repo the "server", so my changes and the other editor's changes both push to that server (so basically the subversion / cvs model); I like mercurial though, and don't want to switch to something like subversion. Here in my own network, everything is done on linux, and my "server" has openssh installed. So pushing my changes (I work on multiple computers) from one computer to the server is just a matter of "hg push"; the protocol used is ssh for transfering the changes. The problem is that I use linux, the server will be windows (so no openssh, right?) and the other editor will be using windows too. As far as I know, the best way of working in mercurial in these types of setups is for the repo to pull changes from the source, rather then the source pushing to the "server". I'm behind several firewall's (not entirely my network) and my computer won't be visible from the server, and I'm assuming the other editor will be behind a firewall too (so we can't just start up the local mercurial http server and get the "server" computer to pull from that). What's the best way for both editors to get our changes to the server repo? (I should add that the server is a server on the internet, so just as visible as something like google.com. It's a hosted windows server, but I would probably have permission to install software if needed for this)

  • Social Networking & Network Affiliations

    - by Code Sherpa
    Hi. I am in the process of planning a database for a social networking project and stumbled upon this url which is a (crude) reverse engineered guess at facebook's schema: http://www.flickr.com/photos/ikhnaton2/533233247/ What is of interest to me is the notion of "Affiliations" and I am trying to fully understand how they work, technically speaking. Where I am somewhat confused is the NetworkID column in the FacebookGroups", "FacebookEvent", and "Affiliations" tables (NID in Affiliations). How are these network affiliations interconnected? In my own project, I have a simple profile table: CREATE TABLE [dbo].[Profiles]( [profileid] [int] IDENTITY(1,1) NOT NULL, [userid] [uniqueidentifier] NOT NULL, [username] [varchar](255) COLLATE Latin1_General_CI_AI NOT NULL, [applicationname] [varchar](255) COLLATE Latin1_General_CI_AI NOT NULL, [isanonymous] [bit] NULL, [lastactivity] [datetime] NULL, [lastupdated] [datetime] NULL, CONSTRAINT [PK__Profiles__1DB06A4F] PRIMARY KEY CLUSTERED ( [profileid] ASC )WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY], CONSTRAINT [PKProfiles] UNIQUE NONCLUSTERED ( [username] ASC, [applicationname] ASC )WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] One profile can have many affiliations. And one affiliation can have many profiles. And I would like to design it in such a way that relationships between affiliations tells me something about the associated profiles. In fact, based on the affiliations that users select, I would like to know how to infer as many things as possible about that person. My question is, how should I be designing my network affiliation tables and how do they operate per my above requirements? A rough SQL schema would be appreciated in your response. Thanks in advance...

  • __declspec(dllimport) causes compiler crash on MSVC 2010

    - by Zero
    In a *.cpp file, trying to use a third party lib: #define DLL_IMPORT #include <thirdParty.h> // Third party header has code like: // #ifdef DLL_IMPORT // #define DLL_DECL __declspec(dllimport) // fatal error C1001: An internal error has occurred in the compiler. Alternative: #define NO_DLL #include <thirdParty.h> // Third party header has code like: // #elif defined(NO_DLL) // #define DLL_DECL // Compiles fine, but linker errors as can't find DLL functions // I can reproduce results by remove macros and #define all together and manually editing the third party files to have __declspec(dllimport) or not Has anyone come across anything similar, or can hint at the cause? (which is created using CMake). Above is actual example of 2 line *.cpp that crashes so it's narrowed down to something in the #include. The following also work fine: Compile the examples provided by the third party (they provide a *.sln) that use dllimport/export so it doesn't appear to be the fault of the library Compile the third party lib as part of the production project (so dllexport works fine) I've trawled the project settings pages of the two projects to try and spot differences, but have come up blank. Of course, it's possible I'm missing something as those settings pages are not the easiest to navigate. I'll get access to VS2008 in a day or so, so can compare with that. The third party library is MySql++.

  • Compiling 32-bit Program on VS 2008

    - by gordonwd
    I've been developing on VC++ 2003 on an XP PC but am now on Windows 7 and bought a cheap legal copy of VS 2008 to continue work on the same project. My product has to continue to run on customers' XP systems, so I'm strictly interested in a 32-bit executable. The first issue I ran into was the PRJ0003 error "spawning cl.exe". I had to add the path to this file to the VC++ Directories settings (it appears in both a bin\amd64 and bin\x86_amd64 directory, but I don't think it matters output-wise which I use?). The issue I now have (not counting a tedious cleanup to convert strcpy to strcpy_s, etc.) is that I'm not clear on whether I'm generating a 32-bit or 64-bit exe out of this. My project properties are set to a target of "Win32", so I assume that all is well. Is this correct? I have read some discussions about this, but it's never quite clear if they are talking about whether the compiler itself is running x64 vs. x86, or whether the compiled code is x64 vs. x86, and how this is differentiated. So am I doing the right thing to generate a 32-bit, Win32, x-86 program?

Does anybody know how to do this - at the moment because the days are going along the top, the package is assuming these are seperate data columns when they are not really and the mapping is not working.
