  • Building a Com addin for Office 2000 / Office 2007

    - by Stuart
    I am struggling to find a straight forward guide to creating office addins using VSTO and VB.net. Specifically I would like to know how to be able to create a addin/ dll which can either be referenced from VBA in the form:- Addin.method(argument) or Addin.property = X Or which would install its own custom toolbars/ ribbon interface to an aspect of office for example Word. I've checked MSDN and in terms of legibility and usability of the explanations I have drawn a blank so far. I currently have a requirement to create at least one addin for Office 2000 to run and manipluate SQL and then a suite of addins for a customized Office 2007 (Word) set-up.

  • What is the best way to read the uploaded files from Request.Files, StreamReader or BinaryReader or

    - by ramesh.nagul
    I have a form where the user can upload multiple files. I am using MVC 2.0 and in my controller I need to call a webservice that is a common import interface requires the files to passed in as byte[]. .NET exposes Request.Files as a HttpFileCollectionBase and I access the filehandle using HttpPostedFile or HttpPostedFileBase that provides access to the Stream member. What is the best way for me to read the bytes from the stream? BinaryReader? StreamReader? BufferedStream?

  • Design Time Attribute For CSS Class in ASP.net Custom Server Control

    - by Jon P
    Hopefully some Custom Control Designers/Builders can help I'm attempting to build my first custom control that is essential a client detail collection form. There are to be a series of elements to this form that require various styles applied to them. Ideally I'd like the VS 2005/2008 properties interface to be able to apply the CSSClass as it does at the control level, i.e. with a dropdown list of available CSS Clases. Take for example the Class to be applied to the legend tag /// <summary>Css Class for Legend</summary> [Category("Appearance")] [Browsable(true)] [DefaultValue("")] //I am at a loss as to what goes in [Editor] [Editor(System.Web.UI.CssStyleCollection), typeof(System.Drawing.Design.UITypeEditor))] public string LegendCSSClass { get { return _LegendCSSClass; } set { _LegendCSSClass = value; } } I have tried a couple of options, as you can see from above, without much luck. Hopefully there is something simple I am missing. I'd also be happy for references pertaining to the [Editor] attribute

  • physics game programming box2d - orientating a turret-like object using torques

    - by egarcia
    This is a problem I hit when trying to implement a game using the LÖVE engine, which covers box2d with Lua scripting. The objective is simple: A turret-like object (seen from the top, on a 2D environment) needs to orientate itself so it points to a target. The turret is on the x,y coordinates, and the target is on tx, ty. We can consider that x,y are fixed, but tx, ty tend to vary from one instant to the other (i.e. they would be the mouse cursor). The turret has a rotor that can apply a rotational force (torque) on any given moment, clockwise or counter-clockwise. The magnitude of that force has an upper limit called maxTorque. The turret also has certain rotational inertia, which acts for angular movement the same way mass acts for linear movement. There's no friction of any kind, so the turret will keep spinning if it has an angular velocity. The turret has a small AI function that re-evaluates its orientation to verify that it points to the right direction, and activates the rotator. This happens every dt (~60 times per second). It looks like this right now: function Turret:update(dt) local x,y = self:getPositon() local tx,ty = self:getTarget() local maxTorque = self:getMaxTorque() -- max force of the turret rotor local inertia = self:getInertia() -- the rotational inertia local w = self:getAngularVelocity() -- current angular velocity of the turret local angle = self:getAngle() -- the angle the turret is facing currently -- the angle of the like that links the turret center with the target local targetAngle = math.atan2(oy-y,ox-x) local differenceAngle = _normalizeAngle(targetAngle - angle) if(differenceAngle <= math.pi) then -- counter-clockwise is the shortest path self:applyTorque(maxTorque) else -- clockwise is the shortest path self:applyTorque(-maxTorque) end end ... it fails. Let me explain with two illustrative situations: The turret "oscillates" around the targetAngle. If the target is "right behind the turret, just a little clock-wise", the turret will start applying clockwise torques, and keep applying them until the instant in which it surpasses the target angle. At that moment it will start applying torques on the opposite direction. But it will have gained a significant angular velocity, so it will keep going clockwise for some time... until the target will be "just behind, but a bit counter-clockwise". And it will start again. So the turret will oscillate or even go in round circles. I think that my turret should start applying torques in the "opposite direction of the shortest path" before it reaches the target angle (like a car braking before stopping). Intuitively, I think the turret should "start applying torques on the opposite direction of the shortest path when it is about half-way to the target objective". My intuition tells me that it has something to do with the angular velocity. And then there's the fact that the target is mobile - I don't know if I should take that into account somehow or just ignore it. How do I calculate when the turret must "start braking"?

  • Calling a running C# application from VBA

    - by Robert
    I have some VBA code that needs to talk to a running c# application. For what it's worth, the c# application runs as a service, and exposes an interface via .net remoting. I posted a question regarding a specific problem I'm having already (http://stackoverflow.com/questions/2556163/from-vb6-to-net-via-com-and-remoting-what-a-mess) but I think I may have my structure all wrong... So I'm taking a step back - what's the best way to go about doing this? One thing that's worth taking into account is that I want to call into the running application - not just call a precompiled DLL...

  • How to store user preferences? Cookie becomes bigger..

    - by ari
    My application (Asp.Net MVC) has great interaction with the user interface (jQuery/js). For example, setting various searches charts, moving the gadgets on the screen and more .. I of course want to keep all data for each user. So that data will be available from any page in the Dumaine and the user will accepts his preferences. Now I keep all data in a cookie because it did not seem logical asynchronous access to the server each time the user changes something and thet happens a lot.When the user logout from the application I save the cookie to the database. The problem is the cookie becomes very large. The thought that this huge cookie is attached to each server request makes me feel that my attitude is wrong. Another problem cookies have size limit. It varies from your browser but I definitely have been close to the border - my cookie easily become 4kb Is there another solution?

  • Can a Flash-based CFGRID render basic HTML in the cells?

    - by richardtallent
    (I'm very new to both Flex and CF -- more a .NET/ExtJS guy, so I'm a duck out of water.) I'm tweaking someone else's CFGRID code. It uses Flash format--HTML isn't an option since it would require redesigning the entire interface around the grid. Tha data I want to put in the grid have some very simple HTML elements-- <sub>, <sup>, and HTML entities like &deg;. I can imagine <i> or <b> might be there in the future. How can I tell a particular CFGRIDCOLUMN to render its contents as HTML? I've heard this is possible, but Google is not my friend tonight. Stuck with CF7 for a few more weeks, so if there are any CF8/CF9-specific solutions, please let me know those as well, but that won't help my immediate need.

  • What is common case for @dynamic usage ?

    - by Forrest
    There is previous post about difference of @synthesize and @dynamic. I wanna to know more about dynamic from the perspective of how to use @dynamic usually. Usually we use @dynamic together with NSManagedObject // Movie.h @interface Movie : NSManagedObject { } @property (retain) NSString* title; @end // Movie.m @implementation Movie @dynamic title; @end Actually there are no generated getter/setter during compiler time according to understanding of @dynamic, so it is necessary to implement your own getter/setter. My question is that in this NSManagedObject case, what is the rough implementation of getter/setter in super class NSManagedObject ? Except above case, how many other cases to use @dynamic ? Thanks,

  • How to mimic SMPP connection

    - by vijay.shad
    Hi, I have a situation. My application is sending multiple SMSes to end client this number varies from 50000 to 100000 SMSes at any point of time. To achieve this functionality i am using Kannel as sms sender interface. So My solution is complete. But only in development environment! Before going to be in production I supposed to do a testing of this solution environment. Is there any suggestion to created a testing environment? To give more input to my environment; kannel is using an smpp connection to deliver messages to end client. So, I think i need to mimic some smpp server for kannel.

  • Is there a Novatel Wireless Modem Emulator or something similar?

    - by David Brown
    Novatel Wireless provides their NovaCore SDK for developers wishing to interface with their line of modems. I'm currently developing an open source managed wrapper for it, but I'm having difficulties with testing. I own a Novatel MiFi and have mobile broadband service through Sprint, but that can only get me so far. The device is already activated, thus I can't test the network activation features of the NovaCore SDK. There are also certain features only available for HSPA modems, which I am not able to get in my area. Is there an emulator capable of emulating a Novatel Wireless modem so that I can test my library without physical hardware and an actual data connection? If not, do you have any other suggestions that might help in this situation? I've contacted Novatel Wireless via email and their developer forum, but have not received a response. Thanks!

  • How write an ads server

    - by Nisanio
    Hi everyone I want to write an ads server (like OpenX), just for fun and learning (they aren't the same). But my idea, more than writing an entire application with web interface and so on, is to write a very tiny core that provides the basic functionality in the most efficient way, like a library that other people can use to write a complete application more fitted to their needs. The objective is to make it small, very efficient and fast. Can someone help me with a list of the minimal functionality needed for this kind of application?. An Ads Server isn't only a banner delivery, there are differents methods (for example OpenX uses a very weird javascript code that i don't understand completely) Any help or guidance is more than welcome...Thanks

  • Application crash when using an NSTimer and pushViewController

    - by Cesar
    I'm using an NSTimer to implement a 3 seconds splash screen. If a don't use a timer the view it's correctly pushed but if I use the timer for adding a little delay the application crash with a EXC_BAD_ACCESS. I'm pretty sure the answer contains "memory management" but I can't get the point... @interface RootViewController : UIViewController { NSTimer *timer; } -(void)changeView:(NSTimer*)theTimer; @property(nonatomic,retain) NSTimer *timer; ... @implementation RootViewController @synthesize timer; - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [[self navigationController] setNavigationBarHidden:YES]; timer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(changeView:) userInfo:nil repeats:NO]; } -(void)changeView:(NSTimer*)theTimer { NSLog(@"timer fired"); //Crash here, but only if called using a timer [[self navigationController] pushViewController:list animated:YES]; }

  • What's the best version control system for handling projects with graphics?

    - by acrosman
    I'm part of a small team (usually just two people), I handle the code, he handles the graphic design. In the past I've used CVS to handle version control of the code files, and while we've included the graphics in the repository, he hasn't derived nearly as much value from it as I have. Are there other packages that provide the better features for supporting graphics? The system would need to have an easy to use GUI interface, as I don't think it's fair to expect a graphic designer to learn command-line tools. Additional aspect: The client software needs to run smoothly on OS X (for the designer), and Windows (for the programmer).

  • Alternate datasource for django model?

    - by slypete
    I'm trying to seamlessly integrate some legacy data into a django application. I would like to know if it's possible to use an alternate datasource for a django model. For example, can I contact a server to populate a list of a model? The server would not be SQL based at all. Instead it uses some proprietary tcp based protocol. Copying the data is not an option, as the legacy application will continue to be used for some time. Would a custom manager allow me to do this? This model should behave just like any other django model. It should even pluggable to the admin interface. What do you think? Thanks, Pete

  • Confusion on using django socialauth

    - by Fedor
    http://github.com/uswaretech/Django-Socialauth/tree/master/socialauth/ I'm a bit confused on how I should use this. Of course, I read the notes at the bottom but I'm a Django novice so I'll need a little hand holding. The structure of this looks like a project structure since it contains a urls.py but I'm also aware that applications can also have that. It also has a manage.py which leads me to believe it's a project ( plus the subdirectories ). So should I just be integrating portions of this into my existing project? This isn't an application, right? The README also mentions grabbing API Keys. So if I want a standard interface where you click on a google/yahoo logo and it forwards itself via Javascript to the authentication page where you login if you already aren't logged in, kicks you back to your own page, would I need API keys? Any other special tips are appreciated.

  • WCF Web Service chnage wsdl name and targetNamespace

    - by Graham
    All, I'm a little new to WCF over IIS but have done some ASMX web services before. My WCF service is up and running but the helper page generated by the web service for me has the default names, i.e. the page that says: You have created a service. To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://localhost:53456/ServicesHost.svc?wsdl In a standard ASMX site I would use method/class attributes to give the web service a name and a namespace. When I click on the link the WSDL has: <wsdl:definitions name="SearchServices" targetNamespace="http://tempuri.org/" i.e. not the WCF Service Contract Name and Namespace from my Interface. I assume the MEX is using some kind of default settings but I'd like to change them to be the correct names. How can I do this?

  • Sqs vs SqsGen2 using RightScale right_aws GEM

    - by Fitter Man
    I'm trying to use the right_aws (1.10.0) GEM with Rails, and I've reduced my problem to a 3-line irb session. The following works require 'rubygems' require 'right_aws' sqs = RightAws::Sqs.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") while this fails require 'rubygems' require 'right_aws' sqs = RightAws::SqsGen2.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") with NameError: uninitialized constant RightAws::SqsGen2. I see the class definition in the GEM source, the documentation is old but seems accurate, but I can't figure out what I'm doing wrong. And while you're at it, is there any reason if I'm building something new, I'd want to use the older interface?

  • solution for COMET and PHP

    - by codemaker
    Is there a real solution for COMET AND PHP combination? Basically, I've come to a point that I need to update a user home page periodically whenever there is new data in the database. As far as I understand, I need to open a persistent connection between my server and my clients browsers to update the contents of their home page as soon as new info. available without dedicating a lot of resources but I had no luck finding anything clear about this issue. I read many articles suggests that PHP is not a good language to implement COMET. My web application is completely programmed in PHP and I don't want to learn another language but if I'm forced to, Would you suggest a good language to start with? Do you think that I can program an interface just to handle this issue? Thanks in advance.

  • How safe am I signing into Google Spreadsheets with yeroon.net/ggplot2

    - by Farrel
    I am impressed by what I have seen of yeroon.net/ggplot2 which is a web interface for Hadley Wickham's R package ggplot2. I want to try it out on my own data. The part that has me very excited is that one can use data stored in one's own Google spreadsheet as the data. One just signs into their Google Account so that yeroon.net/ggplot2 can access the spreadsheet list. I have been hesitant to do it. If I sign in whilst on yeroon.net am I handing over my username and password to a third party? It would not be wise of me to divulge my google password to third parties since Google is fast becoming my repository of everything. How do I know if Jeroon's application is using ClientLogin or OAuth? My understanding is very basic and may be wrong but nevertheless here it is. OAuth would be better since it does not actually pass the password onto the third party application.

  • How can I detect if the Solution is initializing using the DTE in a VisualStudio extension?

    - by justin.m.chase
    I am using the DTE to track when projects are loaded and removed from the solution so that I can update a custom Test Explorer extension. I then trigger a container discovery process. But when the solution is first loaded it does an asynchronous load of some projects and fires a lot of Project Added events. What I would really like to do is to ignore all of these events until the solution is done loading. I can't quite figure out the order of events such that I know for sure that this initialization process has completed. It would be really nice to be able to just query the solution object and ask it. Does anyone know if there is a property or interface or event that I can use to determine this?
