  • UIActionSheet With PickerView not showing up in iPad

    - by user717452
    I am using the following code to add an actionsheet with a picker view on it to my app. From the iPhone, it displays perfectly, but when viewing on iPad (Universal app), it shows a very small pickerview with none of the other buttons right on the center of the page. UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Select Chapter" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Select" otherButtonTitles:nil]; // Add the picker UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0,185,0,0)]; pickerView.delegate = self; pickerView.showsSelectionIndicator = YES; // note this is default to NO [menu addSubview:pickerView]; [menu showFromTabBar:self.tabBarController.tabBar]; [menu setBounds:CGRectMake(0,0,320, 700)]; [pickerView release]; [menu release];

  • Multiple Context menus in PyQt based on mouse location

    - by Nader
    I have a window with multiple tables using QTableWidget (PyQt). I created a popup menu using the right click mouse and it works fine. However, I need to create different popup menu based on which table the mouse is hovering over at the time the right mouse is clicked. How can I get the mouse to tell me which table it is hovering over? or, put in another way, how to implement a method so as to have a specific context menu based on mouse location? I am using Python and PyQt. My popup menu is developed similar to this code (PedroMorgan answer from Qt and context menu): class Foo( QtGui.QWidget ): def __init__(self): QtGui.QWidget.__init__(self, None) # Toolbar toolbar = QtGui.QToolBar() # Actions self.actionAdd = toolbar.addAction("New", self.on_action_add) self.actionEdit = toolbar.addAction("Edit", self.on_action_edit) self.actionDelete = toolbar.addAction("Delete", self.on_action_delete) # Tree self.tree = QtGui.QTreeView() self.tree.setContextMenuPolicy( Qt.CustomContextMenu ) self.connect(self.tree, QtCore.SIGNAL('customContextMenuRequested(const QPoint&)'), self.on_context_menu) # Popup Menu self.popMenu = QtGui.QMenu( self ) self.popMenu.addAction( self.actionEdit ) self.popMenu.addAction( self.actionDelete ) self.popMenu.addSeparator() self.popMenu.addAction( self.actionAdd ) def on_context_menu(self, point): self.popMenu.exec_( self.tree.mapToGlobal(point) )

  • are there any tree libraries/widgets for (n)curses

    - by phatmanace
    Hi - I wondered if there were any tree libraries available for (n)curses. I'm trying to write a component that shows a tree of folders & was curious if there was a prebuilt curses component that could do this. I've checked 'core' curses as well as libraries like CDK - and I can't seem to find anything. If none exists, I'm not averse to building my own - but I can't seem to locate any decent tutorials on doing this, so any help in this regard would also be much appreciated. Thanks, Ace

  • Can't find a Wordpress image/photo gallery plugin

    - by mgroves
    I've been looking at Wordpress plugins for photo galleries (so maybe this is for superuser.com), and I've been very frustrated so far. It seems like what I'd like to do would be a very common use case: Admin: Be able to upload multiple pictures (at a time) Admin: Be able to assign a "gallery" to those pictures as I upload them User: Be able to go to a page with a (paged) list of all galleries User: Be able to click on gallery and view the images (again, probably paged) in that gallery User: Be able to click on an image to get larger/largest sizes User: Be able to leave comments on individual pictures (this is a "nice to have") The images/galleries could be totally independent of posts/pages, but it would be nice to be able to embed those images/galleries into posts/pages when necessary. Is there anything out there like this that I'm missing? I've tried a handful of plugins and none of them seem to be for a use case anywhere close to what I'm looking for. One of the reasons I'm trying to use Wordpress is to reduce time spent coding everything I want.

  • ValidateInput Attribute Doesn't Seem To Work in ASP.NET MVC

    - by JC Grubbs
    I'm trying to get around the "potentially dangerous Request.Form value" error and I'm having no luck. Yes, yes, I've read all the other StackOverflow related questions and none of them seem to get me closer to an answer. I am using [ValidateInput(false)] on all related controller actions...and I've checked many times. I'm using ValidateRequest='false' in all the related ASPX views. I am using ASP.NET MVC 2 Preview 1, but I don't think that's an issue since the error is being generated lower in the framework; Page.ProcessRequest to be exact. I can't see anything I'm doing wrong, I even set <page validateRequest='false'> in the web.config and that didn't solve it either. HELP!!!!!

  • Why do I get a "Day too big" error from Perl?

    - by azp74
    I have been helping someone debug some code where the error message was "Day too big". I know that this springs from localtime and the Y2038 bug (most google results appear to be people dealing with cookies expiring well into the future). We appear to have 'fixed' the problem by using time to get the current date. However, given that none of our original dates should have hit the 2038 issue I'm sceptical that we've actually fixed the problem ... Are there other instances that anyone knows of where one would hit "day too big"? OS is Solaris. Sample code - the actual code is quite large and the person I'm working with hasn't actually isolated the offending part (which is why I'm worried the 'fix' is not actually a fix). If I can put together something concise which reproduces the issue I will post!

  • How to set the size of a wx.aui.AuiManager Pane that is centered?

    - by aF
    Hello, I have three panes with the InfoPane center option. I want to know how to set their size. Using this code: import wx import wx.aui class MyFrame(wx.Frame): def __init__(self, parent, id=-1, title='wx.aui Test', pos=wx.DefaultPosition, size=(800, 600), style=wx.DEFAULT_FRAME_STYLE): wx.Frame.__init__(self, parent, id, title, pos, size, style) self._mgr = wx.aui.AuiManager(self) # create several text controls text1 = wx.TextCtrl(self, -1, 'Pane 1 - sample text', wx.DefaultPosition, wx.Size(200,150), wx.NO_BORDER | wx.TE_MULTILINE) text2 = wx.TextCtrl(self, -1, 'Pane 2 - sample text', wx.DefaultPosition, wx.Size(200,150), wx.NO_BORDER | wx.TE_MULTILINE) text3 = wx.TextCtrl(self, -1, 'Main content window', wx.DefaultPosition, wx.Size(200,150), wx.NO_BORDER | wx.TE_MULTILINE) # add the panes to the manager self._mgr.AddPane(text1, wx.CENTER) self._mgr.AddPane(text2, wx.CENTER) self._mgr.AddPane(text3, wx.CENTER) # tell the manager to 'commit' all the changes just made self._mgr.Update() self.Bind(wx.EVT_CLOSE, self.OnClose) def OnClose(self, event): # deinitialize the frame manager self._mgr.UnInit() # delete the frame self.Destroy() app = wx.App() frame = MyFrame(None) frame.Show() app.MainLoop() I want to know what is called when we change the size of the panes. If you tell me that, I can do the rest by myself :)

  • Why compressed xps are corrupt?

    - by Gio
    compressed xps documents do not pass isxps.exe test and do not display in xpsviewer. i'm using Windows 7 and vs2010. Dim ms = New MemoryStream() Dim P As Package = Package.Open(ms, FileMode.Create, FileAccess.ReadWrite) Dim DocumentUri As Uri = New Uri("pack://document.xps") PackageStore.AddPackage(DocumentUri, P) Dim document As XpsDocument = New XpsDocument(P, CompressionOption.Maximum, DocumentUri.AbsoluteUri) If i change CompressionOption.Maximum to CompressionOption.None all works perfectly. IsXps.exe says "Unable to open Zip archive Error code: 0x8000FFFF", same with default W7 XpsViewer. what i'm doing wrong? (i've also installed latest 7zip program, but i do not think that it may corrupt the default windows zip capability......or not?)

  • sql server datetime

    - by cvista
    hey i have the following query: select * from table where table.DateUpdated >='2010-05-03 08:31:13:000' all the rows in the table being queried have the following DateUpdated: 2010-05-03 08:04:50.000 it returns all of the rows in the table - even though it should return none. I am pretty sure this is because of some crappy date/time regional thing. if i swap the date to be select * from table where table.DateUpdated >='2010-03-05 08:31:13:000' then it does as it should. How can i force everything to be using the same settings? this is doing my head in :) This is sql generated by NHIbernate from my WCF service if that matters. w://

  • VS2008: Disable asking whether to reload files changed outside the IDE

    - by SealedSun
    Hi, I have a Visual Studio 2008 project where some code files are generated with each build (a parser, integrated via MSBuild aka editing the *.csproj file). VS does not know about the generated nature of these files (i.e. they are not the result of a "Custom Tool). So they "change" with every build, naturally. And VS2008 asks me after every build if I would like to reload those files: This file has been modified outside the source Do you want to reload it? That would be ok if I had one of those files opened and in front of me, but I get these modal dialogs even with none of the code files opened. So my question is: Is there a way to disable this dialog, per project, per solution or globally? Thanks!

  • gwt typeahead missing

    - by arinte
    I have a GWT app with a bunch of textboxes. In firefox I would expect that when I type a word in a textbox that I have already typed in and submitted, that firefox would offer to autocomplete that text. But for this GWT app it is not happening. Also in IE it seems that none of my css stuff is loaded. And when I IE developer tools on my GWT page, it can focus in on any of the textboxes it just focuses on the encompassing DIV around all the textboxes.

  • Connection to DB2 in Python

    - by Mestika
    Hi, I'm trying to create a database connection in a python script to my DB2 database. When the connection is done I've to run some different SQL statements. I googled the problem and has read the ibm_db API (http://code.google.com/p/ibm-db/wiki/APIs) but just can't seem to get it right. Here is what I got so far: import sys import getopt import timeit import multiprocessing import random import os import re import ibm_db import time from string import maketrans query_str = None conn = ibm_db.pconnect("dsn=write","usrname","secret") query_stmt = ibm_db.prepare(conn, query_str) ibm_db.execute(query_stmt, "SELECT COUNT(*) FROM accounts") result = ibm_db.fetch_assoc() print result status = ibm_db.close(conn) but I get an error. I really tried everything (or, not everything but pretty damn close) and I can't get it to work. I just need to make a automatic test python script that can test different queries with different indexes and so on and for that I need to create and remove indexes a long the way. Hope someone has a solutions or maybe knows about some example codes out there I can download and study. Thanks Mestika

  • How popular is C++ for making websites/web applications?

    - by Vilx-
    I don't know why this is question is bugging me, but time after time I come back to the though - why not make websites in C++? So far I know of none (except a rumor about Yahoo). Most use PHP, Java or ASP.NET. Some are built on Ruby or Python, but even those are minorities. At the same time, looking at StackOverflow, it seems that C++ is still a very popular language with many projects written in it. Why not for webpages? So - what do you know about this subject? Are there any websites written in C++? Are there any framewroks/libraries that help doing this? Have YOU ever done it? If yes, did you run into any fundamental problems and would you recommend this to others?

  • getResourceAsStream not loading resource in webapp

    - by mangst
    I have a web application that uses a library which resides in TOMCAT_HOME/common/lib. This library looks for a properties file at the root of the classpath (in a class called ApplicationConfig): ApplicationConfig.class.getResourceAsStream("/hv-application.properties"); My Tomcat web application contains this properties file. It is in WEB-INF/classes, which is the root of the classpath right? However, at runtime, when it tries to load the properties file, it throws an exception because it can't find it (getResourceAsStream returns null). Everything works fine if my application is a simple, standalone Java application. Does Tomcat cause the getResourceAsStream method to act differently? I know there's a lot of similar questions out there, but none of them have helped unfortunately. Thanks.

  • Plugin architecture in .net: unloading

    - by henchman
    Hello everybody, I need to implement a plugin architecture within c#/.net in order to load custom user defined actions data type handling code for a custom data grid / conversion / ... from non-static linked assembly files. Because the application has to handle many custom user defined actions, Iam in need for unloading them once executed in order to reduce memory usage. I found several good articles about plugin architectures, eg: ExtensionManager PluginArchitecture ... but none of them gave me enough sausage for properly unloading an assembly. As the program is to be distributed and the user defined actions are (as the name states) user defined: how to i prevent the assembly from executing malicious code (eg. closing my progra, deleting files)? Are there any other pitfalls one of you has encountered?

  • How can I vertically center an element with GWT?

    - by Camille
    Perhaps I haven't been searching the right way but I cannot figure out for the life of me how to center an element using GWT Layout Panels. I'm using UiBinder and I've tried all panels that implement HasVerticalAlignment (DockPanel, HorizontalPanel, VerticalPanel). None of them seem to have any impact from setting vertical alignment (or even horizontal). I've made sure they're taking 100% width and height, inspected the resulting DOM layout from my browser and nothing seems to be changed from those properties. The quick and dirty fix I've figured out is to create my own "CenterPanel" widget which basically is a wrapper around a HTMLPanel with a HTML table with a valign="middle" cell. However, this basically feels like a throwback to the classical css-layout middle centering problems. Surely GWT has something to do this that I've completely overlooked?

  • X11: How do I REALLY grab the mouse pointer?

    - by Drew Hall
    I've implemented a horizontal splitter widget in Xlib. I'm trying to grab the mouse when the user clicks & drags on the splitter bar (so that the user can dynamically move the split & thus resize the windows on either side of the splitter bar). I've used XGrabPointer() after receiving a left click, in hopes that all future mouse motion (dragging) will be diverted to the splitter window until the left button is released. Unfortuntately, it doesn't seem to work like that. If the user drags too quickly and the mouse pointer enters one of the windows on either side of the split, the MotionEvent messages are diverted to that (child) window rather than the splitter window. What have I done wrong? My XGrabPointer() call is as follows: ::XGrabPointer(mDisplay, window, True, ButtonPressMask | ButtonReleaseMask | PointerMotionMask | FocusChangeMask | EnterWindowMask | LeaveWindowMask, GrabModeAsync, GrabModeAsync, RootWindow(mDisplay, DefaultScreen(mDisplay)), None, CurrentTime);

  • [C#] SerialPort not taking input. It throws it back at me!

    - by Mashew
    When I try to write an AT command to my GSM modem, it does not seem to take the command. I have used PuTTY to check that the command words, it does. I have checked to see if the port is opening, it does. What could I possibly be doing wrong? NOTE: The "lol" part is for debugging purposes. ;3 SerialPort sp = new SerialPort("COM3"); sp.BaudRate = 9600; sp.DataBits = 8; sp.StopBits = StopBits.One; sp.Parity = Parity.None; sp.Open(); if (sp.IsOpen == false) { sp.Open(); } Thread.Sleep(1000); sp.WriteLine("AT+CMGF=1"); Thread.Sleep(1000); string lol = sp.ReadExisting(); sp.Close(); return lol;

  • How to pass interface type/GUID reference to an automation method in Delphi

    - by Alan Clark
    In Delphi you can pass class references around to compare the types of objects, and to instantiate them. Can you do the same with interface references being passed to a COM automation server? For example, you can define a method taking a GUID parameter using the type library editor: function ChildNodesOfType(NodeType: TGUID): IMBNode; safecall; In this function I would like to return automation types that support the interface specified by NodeType, e.g. if Supports(SomeNode, NodeType) then result := SomeNode; But the Supports call always fails, I tried passing in the Guids defined in the type library but none of the different types (Ixxx, Class_xxxx, IId_Ixxxx) seem to work.

  • How do I set the timeout on the standalone Flash player in FlexBuilder?

    - by Joshua Fox
    I am using FlexBuilder 3 (which works as an Eclipse plugin). To debug, I launch the standalone Flash players for Flash 9 and 10 from Eclipse. I find that an HTTPService connection on both these version times out after 30 seconds. Flash does not time out when I run the same application in Flash in Firefox or Chrome (I have the debug version of Flash 10 installed there). How can I set the timeout in the standalone Flash player? There seem to be very few config options in the GUI, and none in the Windows registry. Setting HTTPService.requestTimeout programmatically does not help. Alternatively, is there a way to download and install a second copy (which might give me some other default timeout). (I know of the downloadable debug player, but that does not run as a standalone exe.)

  • Condition checking vs. Exception handling

    - by Aidas Bendoraitis
    When is exception handling more preferable than condition checking? There are many situations where I can choose using one or the other. For example, this is a summing function which uses a custom exception: # module mylibrary class WrongSummand(Exception): pass def sum_(a, b): """ returns the sum of two summands of the same type """ if type(a) != type(b): raise WrongSummand("given arguments are not of the same type") return a + b # module application using mylibrary from mylibrary import sum_, WrongSummand try: print sum_("A", 5) except WrongSummand: print "wrong arguments" And this is the same function, which avoids using exceptions # module mylibrary def sum_(a, b): """ returns the sum of two summands if they are both of the same type """ if type(a) == type(b): return a + b # module application using mylibrary from mylibrary import sum_ c = sum_("A", 5) if c is not None: print c else: print "wrong arguments" I think that using conditions is always more readable and manageable. Or am I wrong? What are the proper cases for defining APIs which raise exceptions and why?

  • .NET Thank you/confirmation page best practise

    - by sooty
    Hi, whats the best practise for implementing a confirmation page in .Net? I've used response.redirect("Thankyou.aspx") a lot in the past I've also used something like this for hiding form controls and outputting a message: outResult.Attributes.Remove("style") outResult.Attributes.Add("style", "display:block;") outEntry.Attributes.Remove("style") outEntry.Attributes.Add("style", "display:none;") For the above you have to consider post backs that may occur if the user click refresh though. Does anybody have a better option? thanks!
