  • ADO.net, Check if ObjectContext is writeable

    - by user287107
    I have an embedded database in an asp.net mvc project. If I try to write to the file, I sometimes get a write failed exception because the SQL Server can't write to the file. How can I check an ObjectContext, if its writeable, without actually writing something to the database?

  • Mechanize Javascript ...

    - by Horace Ho
    I try to submit a form by Mechanize, however, I am not sure how to add necessary form valuables which are done by some Javascript. Since Mechanize does not support Javascript yet, and so I try to add the variables manually. The form source: <form name="aspnetForm" method="post" action="list.aspx" language="javascript" onkeypress="javascript:return WebForm_FireDefaultButton(event, '_ctl0_ContentPlaceHolder1_cmdSearch')" id="aspnetForm"> <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__LASTFOCUS" id="__LASTFOCUS" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/..." /> <script type="text/javascript"> <!-- var theForm = document.forms['aspnetForm']; if (!theForm) { theForm = document.aspnetForm; } function __doPostBack(eventTarget, eventArgument) { if (!theForm.onsubmit || (theForm.onsubmit() != false)) { theForm.__EVENTTARGET.value = eventTarget; theForm.__EVENTARGUMENT.value = eventArgument; theForm.submit(); } } // --> </script> <script language="javascript"> <!-- var _linkpostbackhit = 0; function _linkedClicked(id, key, str, a, b) { if (!b || !_linkpostbackhit) { if (!a) { __doPostBack(key, id); _linkpostbackhit = 1; } else { if (window.confirm(str)) { __doPostBack(key, id); _linkpostbackhit = 1; } } } return void(0); } // --> </script> ... <a href="JavaScript:_linkedClicked('123456','_ctl0:ContentPlaceHolder1:Link', '',0,1);">123456</a> ... </form> I tried to add the 2 variables: page.forms.first['__EVENTTARGET'] = '_ctl0:ContentPlaceHolder1:Link' page.forms.first['__EVENTARUGMENT'] = '123456' and submit the form: page.forms.first.click_button(page.forms.first.buttons.first) The result returned only (re)show the current list of links as if I have not clicked on any of the links.

  • Error inflating class android.widget.CompoundButton

    - by snctln
    [Disclaimer: This has been cross posted on the Android Developers Google Group I am trying to use a CompoundButton in a project I am working on. Every time I try and use it by declaring it in my layout xml file I receive the error "01-04 12:27:46.471: ERROR/AndroidRuntime(1771): Caused by: android.view.InflateException: Binary XML file line #605: Error inflating class android.widget.CompoundButton" After fighting the error for a half an hour I decided to try a minimalistic example. I am using the latest eclipse developer tools, and targeting android 2.2 makign the minimum sdk required 2.2 (8). Here is the activity java code: package com.example.CompoundButtonExample; import android.app.Activity; import android.os.Bundle; public class CompoundButtonExampleActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } Here is the layout xml code: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <CompoundButton android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> Here is the manifest xml code: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.CompoundButtonExample" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".CompoundButtonExampleActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="8" /> </manifest> As you can see it is just the default hello world project that eclipse creates for you when you start a new Android project. It only differs in the fact that I add a "CompoundButton" to the main layout in a vertical LinearLayout. Can anyone confirm this bug? Or tell me what I am doing wrong?

Thanks.

  • Catching an exception class within a template

    - by Todd Bauer
    I'm having a problem using the exception class Overflow() for a Stack template I'm creating. If I define the class regularly there is no problem. If I define the class as a template, I cannot make my call to catch() work properly. I have a feeling it's simply syntax, but I can't figure it out for the life of me. #include<iostream> #include<exception> using namespace std; template <class T> class Stack { private: T *stackArray; int size; int top; public: Stack(int size) { this->size = size; stackArray = new T[size]; top = 0; } ~Stack() { delete[] stackArray; } void push(T value) { if (isFull()) throw Overflow(); stackArray[top] = value; top++; } bool isFull() { if (top == size) return true; else return false; } class Overflow {}; }; int main() { try { Stack<double> Stack(5); Stack.push( 5.0); Stack.push(10.1); Stack.push(15.2); Stack.push(20.3); Stack.push(25.4); Stack.push(30.5); } catch (Stack::Overflow) { cout << "ERROR! The stack is full.\n"; } return 0; } The problem is in the catch (Stack::Overflow) statement. As I said, if the class is not a template, this works just fine. However, once I define it as a template, this ceases to work. I've tried all sorts of syntaxes, but I always get one of two sets of error messages from the compiler. If I use catch(Stack::Overflow): ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2316: 'Stack::Overflow' : cannot be caught as the destructor and/or copy constructor are inaccessible EDIT: I meant If I use catch(Stack<double>::Overflow) or any variety thereof: ch18pr01.cpp(89) : error C2061: syntax error : identifier 'Stack' ch18pr01.cpp(89) : error C2310: catch handlers must specify one type ch18pr01.cpp(95) : error C2317: 'try' block starting on line '75' has no catch handlers I simply can not figure this out. Does anyone have any idea?

  • C# multi CPU for ThreadPool.QueueUserWorkItem

    - by ikurtz
    I have a program that uses: ThreadPool.QueueUserWorkItem(new WaitCallback(FireAttackProc), fireResult); On Windows7 and Vista it works fine. When I try to run it on XP the result is a bit different from the others. I was just wondering in order to execute QueueUserWorkItem properly do I need a dual CPU system? The XP I tried to test on had .Net 3.5 installed. Inputs most welcome.

  • How to draw onto a PictureBox image when control resizes?

    - by Sam Mackrill
    I am using the pictureBox_Paint event to try and draw an overlay onto the image in a PictureBox. This is working fine until I resize the PictureBox (set to use SizeMode.Zoom), when I do this the overlay graphic is drawn off position by the margin between the image and the edge of the PictureBox. I guess I need to use the ImageRectangle somehow but this is not public.

    Usually when you try to add a marker to an unknown/ambiguous address you just get an error from the api. It would be much nicer if i could display a list of suggestions related to the address that was not found. The Google maps site has this feature but i do not know how to do with the api. Any help would be appreciated.

  • PyGTK: dynamic label wrapping

    - by detly
    It's a known bug/issue that a label in GTK will not dynamically resize when the parent changes. It's one of those really annoying small details, and I want to hack around it if possible. I followed the approach at 16 software, but as per the disclaimer you cannot then resize it smaller. So I attempted a trick mentioned in one of the comments (the set_size_request call in the signal callback), but this results in some sort of infinite loop (try it and see). Does anyone have any other ideas? (You can't block the signal just for the duration of the call, since as the print statements seem to indicate, the problem starts after the function is left.) The code is below. You can see what I mean if you run it and try to resize the window larger and then smaller. (If you want to see the original problem, comment out the line after "Connect to the size-allocate signal", run it, and resize the window bigger.) The Glade file ("example.glade"): <?xml version="1.0"?> <glade-interface> <!-- interface-requires gtk+ 2.16 --> <!-- interface-naming-policy project-wide --> <widget class="GtkWindow" id="window1"> <property name="visible">True</property> <signal name="destroy" handler="on_destroy"/> <child> <widget class="GtkLabel" id="label1"> <property name="visible">True</property> <property name="label" translatable="yes">In publishing and graphic design, lorem ipsum[p][1][2] is the name given to commonly used placeholder text (filler text) to demonstrate the graphic elements of a document or visual presentation, such as font, typography, and layout. The lorem ipsum text, which is typically a nonsensical list of semi-Latin words, is a hacked version of a Latin text by Cicero, with words/letters omitted and others inserted, but not proper Latin[1][2] (see below: History and discovery). The closest English translation would be "pain itself" (dolorem = pain, grief, misery, suffering; ipsum = itself).</property> <property name="wrap">True</property> </widget> </child> </widget> </glade-interface> The Python code: #!/usr/bin/python import pygtk import gobject import gtk.glade def wrapped_label_hack(gtklabel, allocation): print "In wrapped_label_hack" gtklabel.set_size_request(allocation.width, -1) # If you uncomment this, we get INFINITE LOOPING! # gtklabel.set_size_request(-1, -1) print "Leaving wrapped_label_hack" class ExampleGTK: def __init__(self, filename): self.tree = gtk.glade.XML(filename, "window1", "Example") self.id = "window1" self.tree.signal_autoconnect(self) # Connect to the size-allocate signal self.get_widget("label1").connect("size-allocate", wrapped_label_hack) def on_destroy(self, widget): self.close() def get_widget(self, id): return self.tree.get_widget(id) def close(self): window = self.get_widget(self.id) if window is not None: window.destroy() gtk.main_quit() if __name__ == "__main__": window = ExampleGTK("example.glade") gtk.main()

  • Is deep Java knowledge needed for Android?

    - by MigNix
    Hi, I am C++ developer interested in Android. As I understand the only possibility to develop applications for Android is Java. There is NDK also, but as I can see it is just something like JNI for Java. Is it mandatory to learn Java or to have deep knowledge in Java then try Android SDK, or it would be possible to learn Java while developing for Android. Thank you.
