  • Android xml Array returning 0 for getIndexCount()

    - by user1459976
    i'm storing data in an xml array in this fashion <resources> <array name="myarray"> <item> <item>attribute1</item> <item>attribute2</item> <item>and so on</item> </item> <item> <item>attribute1</item> <item>attribute2</item> <item>and so on</item> </item> <item> <item>attribute1</item> <item>attribute2</item> <item>and so on</item> </item> </array> </resources> // in program TypedArray array = getResources().obtainTypedArray(R.array.myarray); when i call array.getIndexCount() in the program it returns 0, what is wrong?

  • crash when using stl vector at instead of operator[]

    - by Jamie Cook
    I have a method as follows (from a class than implements TBB task interface - not currently multithreading though) My problem is that two ways of accessing a vector are causing quite different behaviour - one works and the other causes the entire program to bomb out quite spectacularly (this is a plugin and normally a crash will be caught by the host - but this one takes out the host program as well! As I said quite spectacular) void PtBranchAndBoundIterationOriginRunner::runOrigin(int origin, int time) const // NOTE: const method { BOOST_FOREACH(int accessMode, m_props->GetAccessModes()) { // get a const reference to appropriate vector from member variable // map<int, vector<double>> m_rowTotalsByAccessMode; const vector<double>& rowTotalsForAccessMode = m_rowTotalsByAccessMode.find(accessMode)->second; if (origin != 129) continue; // Additional debug constrain: I know that the vector only has one non-zero element at index 129 m_job->Write("size: " + ToString(rowTotalsForAccessMode.size())); try { // check for early return... i.e. nothing to do for this origin if (!rowTotalsForAccessMode[origin]) continue; // <- this works if (!rowTotalsForAccessMode.at(origin)) continue; // <- this crashes } catch (...) { m_job->Write("Caught an exception"); // but its not an exception } // do some other stuff } } I hate not putting in well defined questions but at the moment my best phrasing is : "WTF?" I'm compiling this with Intel C++ 11.0.074 [IA-32] using Microsoft (R) Visual Studio Version 9.0.21022.8 and my implementation of vector has const_reference operator[](size_type _Pos) const { // subscript nonmutable sequence #if _HAS_ITERATOR_DEBUGGING if (size() <= _Pos) { _DEBUG_ERROR("vector subscript out of range"); _SCL_SECURE_OUT_OF_RANGE; } #endif /* _HAS_ITERATOR_DEBUGGING */ _SCL_SECURE_VALIDATE_RANGE(_Pos < size()); return (*(_Myfirst + _Pos)); } (Iterator debugging is off - I'm pretty sure) and const_reference at(size_type _Pos) const { // subscript nonmutable sequence with checking if (size() <= _Pos) _Xran(); return (*(begin() + _Pos)); } So the only difference I can see is that at calls begin instead of simply using _Myfirst - but how could that possibly be causing such a huge difference in behaviour?

  • Web Crawler C# .Net

    - by sora0419
    I'm not sure if this is actually called the web crawler, but this is what I'm trying to do. I'm building a program in visual studio 2010 using C# .Net. I want to find all the urls that has the same first part. Say I have a homepage: www.mywebsite.com, and there are several subpage: /tab1, /tab2, /tab3, etc. Is there a way to get a list of all urls that begins with www.mywebsite.com? So by providing www.mywebsite.com, the program returns www.mywebsite.com/tab1, www.mywebsite.com/tab2, www.mywebsite.com/tab3, etc. ps. I do not know how many total sub pages there are. --edit at 12:04pm-- sorry for the lack of explanation. I want to know how to write a crawler in C# that do the above task. All I know is the main url www.mywebsite.com, and the goal is to find all its sub pages. -- edit at 12:16pm-- Also, there is no links on the main page, the html is basically blank. I just know that the subpages exist, but have no way to link to it except for providing the exact urls.

  • Acessing a wordpress database from an iPhone App.

    - by Code
    Hi guys, I've been asked to create an app that will get data back from a database where the CMS will be Wordpress. I've never used a CMS so I'm trying to get a (overview)picture in my head of how it could all work and what each of the components would be. And what a CMS actually brings to the party. Creating the app itself is pretty clear. I've done a few already. I've made a database before and shouldnt cause a problem. But what is going to be in the middle between the app and the database? Part A: I'm guessing iphone apps typically would call some php file that's hosted on the server? The php then would make a call to the database and return the data somehow, maybe as xml. But this is really basic and wouldnt require a CMS. Just a database and a phpfile, or am I wrong? Part B: If i wanted to run a check on the database every minute to see if any of the data in database was no longer valid and remove it if needed, that would require somekind of program running on the server. So that program would be Wordpress, since it is managing the content, so a content management system is actually needed and is for these kind of taskes. Am i understanding the role of CMS? Many Thanks, -Code

  • Getting path of file copied after deployment in a unit test C#

    - by amitchd
    Hi, The connection string in my app.config for my C# project looks like Data Source=.\SQLEXPRESS;AttachDbFilename='|DataDirectory|\EIC.mdf';Integrated Security=True;User Instance=True" I am writing unit tests for the project and have the set the test run configuration to copy the EIC.mdf, but I do am not able to reference the Deployed copy of EIC.mdf to be referenced by the app.config I created for the test project. If I set it to Data Source=.\SQLEXPRESS;AttachDbFilename='EIC.mdf';Integrated Security=True;User Instance=True" It still does not find the mdf file.

  • How to re-enable the context menu in this case?

    - by lemonedo
    document.addEventListener('contextmenu', function (e) { e.preventDefault() e.stopPropagation() e.returnValue = false e.cancleBubble = true }) No way? Edit: document.oncontextmenu = null does not work. P.S. I cannot have the reference of the listener function since I am not the owner of the site preventing the context menu.

  • wxPython: MainLoop() seems to hang

    - by BandGap
    Hi all, my problem stems from the use of wxApp as far as I can tell. Inside a litte subroutine I call a wx.MessageDialog to ask for a yes or no. I retrieve the answer an process some stuff acordingly. My example code below actually works (though it might be ugly) except that the Dialog box stays open after hitting one of the buttons... import wx from os import path def HasFile(filename): if path.isfile(filename ): app = wx.App() dial = wx.MessageDialog(None, 'Die Datei "'+filename+'" wurde gefunden.\nSoll sie eingelesen werden?', 'Bitte antworten', wx.YES_NO | wx.YES_DEFAULT | wx.ICON_QUESTION) result = dial.ShowModal() dial.EndModal(retCode=0) dial.Destroy() app.MainLoop() return result == wx.ID_YES else: return False So while the rest of the program does whatever is expected, the box just sits there. It also seems like my calls to matplotlib later on are producing errors (a Tkinter error to be precise), maybe because of the wx stuff? Edit: I tried to end the app with a call to app.Destroy(). This doesn't change the fact that the box is still there. When I issue a app.IsActive() afterwards the whole program exits (almost like a sys.exit())! How come? Edit 2: Adding a wxApp like this isn't a good idea since the other scripts get affected as well. Subsequent plotting commands don't get displayed and I don't know how to fix this. Thus I decided to remove the DialogBox alltogether.

  • Printing Images C# Overlapping Wrong

    - by Alen
    I have created a program much like Photoshop in the sense that you can place images (picture box) on a control, move them around, delete them, and so on... I have also managed to put together a method to print all the images on the control with no problems. But here is the weird part: When I click print, the program prints the image which was placed first, on top of the image which came second. On the screen the user can see the image which was placed second, on top of the first placed image (the way it should be) but when I print its opposite? I have no idea why it does this... I hope I've made my self as clear as possible, any help is appreciated! public void printToGraphics(Graphics graphics, Rectangle bounds) { graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit; graphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality; graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality; Bitmap bitmap = new Bitmap(newLabel.Width, newLabel.Height); newLabel.DrawToBitmap(bitmap, newLabel.DisplayRectangle); Rectangle target = new Rectangle(0, 0, bounds.Width, bounds.Height); target.Height = bitmap.Height; target.Width = bitmap.Width; graphics.PageUnit = GraphicsUnit.Display; graphics.DrawImage(bitmap,target); } void printDoc_PrintPage(object sender, PrintPageEventArgs e) { printToGraphics(e.Graphics, e.MarginBounds); }

  • Freeing of allocated memory in Solaris/Linux

    - by user355159
    Hi, I have written a small program and compiled it under Solaris/Linux platform to measure the performance of applying this code to my application. The program is written in such a way, initially using sbrk(0) system call, i have taken base address of the heap region. After that i have allocated an 1.5GB of memory using malloc system call, Then i used memcpy system call to copy 1.5GB of content to the allocated memory area. Then, I freed the allocated memory. After freeing, i used again sbrk(0) system call to view the heap size. This is where i little confused. In solaris, eventhough, i freed the memory allocated (of nearly 1.5GB) the heap size of the process is huge. But i run the same application in linux, after freeing, i found that the heap size of the process is equal to the size of the heap memory before allocation of 1.5GB. I know Solaris does not frees memory immediately, but i don't know how to tune the solaris kernel to immediately free the memory after free() system call. Also, please explain why the same problem does not comes under Linux? Can anyone help me out of this? Thanks, Santhosh.

  • Read data from form

    - by Superhuman
    This is a strange question, I've never tried to do this before. I have a repetitive process requiring that I copy and paste data from text boxes in one program into another program for further processing. I'd like to automate this process using VB .NET. The application from which the data is gathered isn't mine, so I don't have ActiveX-like access to its controls. How would you write an application to gain access to a form from another application, to be able to find the controls on the form, and gather the values from them? Just experimenting, I've used the following code. This resulted in only the name of the form to which this code belongs. It didn't find the names of any other forms I have open, and I have a lot open to choose from. This is frustrating because it's only step one of what I'll need to do to make my life easier... Public Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As CallBack, ByVal lParam As Integer) As Integer Public Delegate Function CallBack(ByVal hwnd As IntPtr, ByVal lParam As IntPtr) As Boolean Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim cb As New CallBack(AddressOf MyCallBack) EnumWindows(cb, 8) End Sub Public Function MyCallBack(ByVal hwnd As Long, ByVal lparam As Long) As Boolean Dim frm As System.Windows.Forms.Control frm = System.Windows.Forms.Form.FromHandle(hwnd) If frm Is Nothing Then Return True If frm.Text <> "" Then TextBox1.Text += frm.Text & ", " End If Return True End Function Does anyone have a recommendation? Thanks, SH

  • Finding the Largest and Smallest Integers In A Set- Basic

    - by Ka112324
    I'm kind of on the right track, however my output is not quite right. The program asks for the number of integers you have and then it asks for those numbers. For an example is says please enter the number of integers, you can put 3. And then you enter 3 numbers. I can't use arrays because I am a beginner student and we have not learned those yet. Using count is the only way that allows me to input integers. What do I need to add to my program? Again I am a general computer science student so I can't use anything advanced. I used include iostream, namespace int main and all that you just cant see it int data; int num; int count=0; int max=0; do { cout<<"Enter the number of intergers"<<endl; cin>>num; while (count<num) { cout<<"Please enter a number"<<endl; cin>>data; count++; if (data<min) { min=data; } if (data>max) { max=data; } } cout<<"Smallest integer:"<<min<<endl; cout<<"Largest integer:"<<max<<endl; cout<<"Would you like to continue?"<<endl; cin>>ans; } while ((ans=='y')||(ans=='Y')); return 0; }

    How to declare a static dictionary object inside a static class? I tried public static class ErrorCode { public const IDictionary<string , string > ErrorCodeDic =new Dictionary<string, string>() { {"1","User name or password problem"} }; } But the compiler complains that "A const field of a reference type other than string can only be initialized with null".

  • How to set up an Eclipse P2 server using Google Sites?

    - by PaulB
    I'm trying to use Google Sites to host an Eclipse P2 site. However, Install New Software fails to the site because the features and plugins directories are not found. It seems that Google Sites only simulates subdirectories on FileCabinet pages. Is there an alternative Google Sites approach? Or is there a way to set up a P2 site without subdirectories or so that Install New Software will reference a zip file? Any alternative recommendations?

  • Same random numbers from instantiated class

    - by user1797202
    I'm learning C# and created a class within my program that holds a random number generator: class RandomNumberGenerator { Random RNG = new Random(); // A bunch of methods that use random numbers are in here } Inside this class are a few methods that use the RNG. Data gets sent here from other parts of the program, gets processed, then gets returned. One of the methods does the following: // Method works something like this int Value1 = RNG.Next(x, y); int Value2 = RNG.Next(x, y); int Value3 = RNG.Next(x, y); The x, y values are to be sent here from another class. So, I have to create an instance of the RandomNumberGenerator within that class so I can call its methods and pass the x and y values to it. class DoStuff { RandomNumberGenerator Randomizer = new RandomNumberGenerator // Here I call a bunch of Randomizer methods that give me values I need } The problem in the above method is that I get the same numbers every time for all three values. I'm not sure if it's because they're so close together and Randomizer's seed value hasn't had time to change or if I'm doing something wrong when I create a new instance of the RandomNumberGenerator class. I've gone through a bunch of answers on here already and typically problems like this are due to people creating many new Random objects when they run methods (thus setting the seed for all of them to the same value), but the only new Random object I create is within the RandomNumberGenerator class. I then instantiate that once within the other class so I can pass it data and use its methods. Why is this happening and how would I fix this?

  • Can the size of a structure change after compiled?

    - by Sarah Altiva
    Hi, suppose you have the following structure: #include <windows.h> // BOOL is here. #include <stdio.h> typedef struct { BOOL someBool; char someCharArray[100]; int someIntValue; BOOL moreBools, anotherOne, yetAgain; char someOthercharArray[23]; int otherInt; } Test; int main(void) { printf("Structure size: %d, BOOL size: %d.\n", sizeof(Test), sizeof(BOOL)); } When I compile this piece of code in my machine (32-bit OS) the output is the following: Structure size: 148, BOOL size: 4. I would like to know if, once compiled, these values may change depending on the machine which runs the program. E.g.: if I ran this program in a 64-bit machine, would the output be the same? Or once it's compiled it'll always be the same? Thank you very much, and forgive me if the answer to this question is obvious...
