  • Problem with connection to MS SQL Server database using SSMS

    - by Charles
    I have a database on line with Godaddy (who uses SQL Server 2005). They provide basic management tools, but tell you that for more advanced tools you can connect directly using SSMS. I followed their instructions to ensure my online database will accept remote connections, and can apparently log in using SSMS with success (after giving my hostname and access data). However: When attempting to expand the "Databases" folder tree, I get the following error: Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server& LinkId=20476 ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) The server principal "cmitchell" is not able to access the database "3pointdb" under the current security context.

  • How many layers are between my program and the hardware?

    - by sub
    I somehow have the feeling that modern systems, including runtime libraries, this exception handler and that built-in debugger build up more and more layers between my (C++) programs and the CPU/rest of the hardware. I'm thinking of something like this: 1 + 2 OS top layer Runtime library/helper/error handler a hell lot of DLL modules OS kernel layer Do you really want to run 1 + 2?-Windows popup (don't take this serious) OS kernel layer Hardware abstraction Hardware Go through at least 100 miles of circuits Eventually arrive at the CPU ADD 1, 2 Go all the way back to my program Nearly all technical things are simply wrong and in some random order, but you get my point right? How much longer/shorter is this chain when I run a C++ program that calculates 1 + 2 at runtime on Windows? How about when I do this in an interpreter? (Python|Ruby|PHP) Is this chain really as dramatic in reality? Does Windows really try "not to stand in the way"? e.g.: Direct connection my binary < hardware?

  • Exit Tks mainloop in Python?

    - by Olof
    I'm writing a slideshow program with Tkinter, but I don't know how to go to the next image without binding a key. import os, sys import Tkinter import Image, ImageTk import time root = Tkinter.Tk() w, h = root.winfo_screenwidth(), root.winfo_screenheight() root.overrideredirect(1) root.geometry("%dx%d+0+0" % (w, h)) root.focus_set() root.bind("<Escape>", lambda e: e.widget.quit()) image_path = os.path.join(os.getcwd(), 'images/') dirlist = os.listdir(image_path) for f in dirlist: try: image = Image.open(image_path+f) tkpi = ImageTk.PhotoImage(image) label_image = Tkinter.Label(root, image=tkpi) # ? label_image.place(x=0,y=0,width=w,height=h) root.mainloop(0) except IOError: pass root.destroy() I would like to add a time.sleep(10) "instead" of the root.mainloop(0) so that it would go to the next image after 10s. Now it changes when I press ESC. How can I have a timer there?

  • How to segue modal without losing tab bar controller

    - by Arian
    Okay, so I want to be able to have a TabBar Controller with two Tabs (like the template in Xcode), but inside the Second tab, I want to have a button that takes the view to a Third View Controller. I want the Third View Controller to have a back button to the Second Tab, I don't want the Third View to retain the TabBar, but when I go back to the Second Tab I want the TabBar to return. So this is what I actually did, and it doesn't work. I put a button in 2nd view and 3rd view, and I control clicked and dragged to the respective views, and clicked modal. Everything works, except when I go back to the 2nd view I lose the tab bar. Pictures of what I am talking about: http://s13.postimage.org/78gqghflj/Screen_Shot_2012_07_09_at_2_03_41_PM.png http://s16.postimage.org/gdwus4w6t/i_OS_Simulator_Screen_shot_Jul_9_2012_2_02_50_PM.png http://s10.postimage.org/5uq3ste7d/i_OS_Simulator_Screen_shot_Jul_9_2012_2_02_57_PM.png http://s8.postimage.org/gpmsx959x/i_OS_Simulator_Screen_shot_Jul_9_2012_2_03_54_PM.png

  • vb.net array for slideshow button

    - by StealthRT
    Hey all, i am in the middle of trying to figure out how to go about doing this... I have a form that i call like so: call frmSlideShow.showWhat(1,4,8,9,11,22) Each of the numbers represents a different image slide (slide1.png, slide4.png, etc..). The problem i am having is trying to create a "previous" and "next" button to flip through them all. Trying to figure out what number the user is on and going from there and seeing what numbers are still left from the list above that was sent, etc. If anyone has an idea how i would go about doing that then that would be awesome! :) David

  • Compiling for older versions of Mac OS X

    - by Tristan
    I have recently started producing applications for the Mac, on my most recent release I got overwhelming suggestions to get the app working on OSX 10.5 as I'm working in and compiling for 10.6. I tried looking for the 10.5 SDK but couldn't find it anywhere to download! How can I go about compiling my app for older versions of Mac OS X using Xcode 2.2 and developing in 10.6? EDIT: ------ I will mention I don't have the to option to select different SDKs as I don't have any others installed and my problem is more not being able to find where to get those sdks from? then actually not know how to go about compiling for the older sdks

  • SSL confirmation dialog popup auto closes in IE8 when re-accessing a JNLP file

    - by haylem
    I'm having this very annoying problem to troubleshoot and have been going at it for way too many days now, so have a go at it. The Environment We have 2 app-servers, which can be located on either the same machine or 2 different machines, and use the same signing certificate, and host 2 different web-apps. Though let's say, for the sake of our study case here, that they are on the same physical machine. So, we have: https://company.com/webapp1/ https://company.com/webapp2/ webapp1 is GWT-based rich-client which contains on one of its screens a menu with an item that is used to invoke a Java WebStart Client located on webapp2. It does so by performing a simple window.open call via this GWT call: Window.open("https://company.com/webapp2/app.jnlp", "_blank", null); Expected Behavior User merrilly goes to webapp1 User navigates to menu entry to start the WebStart app and clicks on it browser fires off a separate window/dialog which, depending on the browser and its security settings, will: request confirmation to navigate to this secure site, directly download the file, and possibly auto-execute a javaws process if there's a file association, otherwise the user can simply click on the file and start the app (or go about doing whatever it takes here). If you close the app, close the dialog, and re-click the menu entry, the same thing should happen again. Actual Behavior On Anything but God-forsaken IE 8 (Though I admit there's also all the god-forsaken pre-IE8 stuff, but the Requirements Lords being merciful we have already recently managed to make them drop these suckers. That was close. Let's hold hands and say a prayer of gratitude.) Stuff just works. JNLP gets downloaded, app executes just fine, you can close the app and re-do all the steps and it will restart happily. People rejoice. Puppies are safe and play on green hills in the sunshine. Developers can go grab a coffee and move on to more meaningful and rewarding tasks, like checking out on SO questions. Chrome doesn't want to execute the JNLP, but who cares? Customers won't get RSI from clicking a file every other week. On God-forsaken IE8 On the first visit, the dialog opens and requests confirmation for the user to continue to webapp2, though it could be unsafe (here be dragons, I tell you). The JNLP downloads and auto-opens, the app start. Your breathing is steady and slow. You close the app, close that SSL confirmation dialog, and re-click the menu entry. The dialog opens and auto-closes. Nothing starts, the file wasn't downloaded to any known location and Fiddler just reports the connection was closed. If you close IE and reach that menu item to click it again, it is now back to working correctly. Until you try again during the same session, of course. Your heart-rate goes up, you get some more coffee to make matters worse, and start looking for plain tickets online and a cheap but heavy golf-club on an online auction site to go clubbing baby polar seals to avenge your bloodthirst, as the gates to the IE team in Redmond are probably more secured than an ice block, as one would assume they get death threats often. Plus, the IE9 and IE10 teams are already hard at work fxing the crap left by their predecessors, so maybe you don't want to be too hard on them, and you don't have money to waste on a PI to track down the former devs responsible for this mess. Added Details I have come across many problems with IE8 not downloading files over SSL when it uses a no-cache header. This was indeed one of our problems, which seems to be worked out now. It downloads files fine, webapp2 uses the following headers to serve the JNLP file: response.setHeader("Cache-Control", "private, must-revalidate"); // IE8 happy response.setHeader("Pragma", "private"); // IE8 happy response.setHeader("Expires", "0"); // IE8 happy response.setHeader("Access-Control-Allow-Origin", "*"); // allow to request via cross-origin AJAX response.setContentType("application/x-java-jnlp-file"); // please exec me As you might have inferred, we get some confirmation dialog because there's something odd with the SSL certificate. Unfortunately I have no control over that. Assuming that's only temporary and for development purposes as we usually don't get our hands on the production certs. So the SSL cert is expired and doesn't specify the server. And the confirmation dialog. Wouldn't be that bad if it weren't for IE, as other browsers don't care, just ask for confirmation, and execute as expected and consistantly. Please, pretty please, help me, or I might consider sacrificial killings as an option. And I think I just found a decently prized stainless steel golf-club, so I'm right on the edge of gore. Side Notes Might actually be related to IE8 window.open SSL Certificate issue. Though it doesn't explain why the dialog would auto-close (that really is beyong me...), it could help to not have the confirmation dialog and not need the dialog at all. For instance, I was thinking that just having a simple URL in that menu instead of have it entirely managed by GWT code to invoke a Window.open would solve the problem. But I don't have control on that menu, and also I'm very curious how this could be fixed otherwise and why the hell it happens in the first place...

  • jQuery stopPropagation bubble down

    - by Jasie
    I have a div with a link inside of it: <div id="myDiv"> <a href="http://www.lol.com">Lol</a> </div> Clicking the <div /> should go somewhere, but clicking the child <a /> should go to www.lol.com. I've seen from previous questions and the jQuery website that .stopPropagation prevents bubbling upwards, but how do I prevent a bubble downwards (isn't that what's necessary here?).

  • Popping multiple levels in UITableViewController

    - by LavaSlider
    I would like to be able to pop multiple views from a UITableViewController stack. For example in the Apple DrillDownSave example, when viewing Level 3 to go back to Level 1 or when viewing an Item to go back to Level 2 when a button is pushed. I tried: [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; [self.navigationController popViewControllerAnimated: NO]; and [self.navigationController popViewControllerAnimated: NO]; [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; but these leave me the same place as just a single popViewControllerAnimated:. Is there an easy way to do this?

  • How can I build a Truth Table Generator?

    - by KingNestor
    I'm looking to write a Truth Table Generator as a personal project. There are several web-based online ones here and here. (Example screenshot of an existing Truth Table Generator) I have the following questions: How should I go about parsing expressions like: ((P = Q) & (Q = R)) = (P = R) Should I use a parser generator like ANTLr or YACC, or use straight regular expressions? Once I have the expression parsed, how should I go about generating the truth table? Each section of the expression needs to be divided up into its smallest components and re-built from the left side of the table to the right. How would I evaluate something like that? Can anyone provide me with tips concerning the parsing of these arbitrary expressions and eventually evaluating the parsed expression?

  • Why use MySQL over flatfiles?

    - by John
    A friend and I were debating about whether he should use MySQL or a flatfile database for his website's backend. I told him to go with MySQL because it was structured, held records well, and was consistent. He on the other hand said that he would rather go for speed. Reading files is a lot quicker than connecting to MySQL and it made me wonder whether he was right. For example, why not just create a folder for each table, like so: users/ groups/ posts/, within the folders have the files named by ID (1, 2, 3) and then for the data use a format like so: username: John\npassword: e2fc714c4727ee9395f324cd2e7f331f\nemail: [email protected]? In other words, what are the advantages of MySQL over flatfiles?

  • Google app engine or Amazin ec2 for Restful services and direct access to datastore

    - by imran
    I'm thinking of building a Restful app on either App engine or ec2 devloped in Java. I'm interested in opinions/experience of using the two options for this. The primary purpose is to create web services to write and retrieve data through a mobile device...basically creating an API for the service I want to create. It seems to me it would be quicker and cheaper in the beginning to go with google app engine using either restlet or grails.But I also think that I could run into problems in the future when I want to so somthing more advanced and might be restricted by app engines environment. I also want to be able to do data analysis on the data in the datastore as well. It seems that with app engine this would be hard as I don't have direct access to the datastore ( in Amazon I could still have access to the underlying db if I go with MySQL ) .

  • T-SQL foreign key check constraint

    - by PaN1C_Showt1Me
    When you create a foreign key constraint in a table and you create the script in MS SQL Management Studio, it looks like this. ALTER TABLE T1 WITH CHECK ADD CONSTRAINT FK_T1 FOREIGN KEY(project_id) REFERENCES T2 (project_id) GO ALTER TABLE T1 CHECK CONSTRAINT FK_T1 GO What I don't understand is what purpose has the second alter with check constraint. Isn't creating the FK constraint enough? Do you have to add the check constraint to assure reference integrity ? Another question: how would it look like then when you'd write it directly in the column definition? CREATE TABLE T1 ( my_column INT NOT NULL CONSTRAINT FK_T1 REFERENCES T2(my_column) ) Isn't this enough?

  • How to Setup an RSS Feed using Feedburner?

    - by Derick K.
    I've searched Google, but only found information on how to setup a feedburner for wordpress or other blogging services. I've also searched stackoverflow, but not found the right information. I'm creating a website, for which I want to have an RSS. Feedburner seems to be a good, free option - so I'd like to use that. When I go to feedburner, using my google account, it says the website I want to claim is invalid. And it's not clear how to make it valid. I also have no experience with RSS (and really websites in general), so I'm not sure where to go from here. What are the steps I need to take, starting from scratch, to add an RSS feed (with feedburner) to a website?

  • External Javascript Timeout

    - by yummm
    I have a number of tracking scripts and web services installed on my website and I noticed when one of the services goes down, it still tries to call the external javascript file hosted on a different server. In Firefox, Chrome and other new browsers, there doesn't seem to be any issues when one of the services go down. However, in IE7 and IE8, my pages don't load all the way and time out before everything is displayed. Is there any way to add a time out on these javascript calls to prevent them from breaking my pages when they go down?

  • Is there a lightweight multipart/form-data parser in C or C++?

    - by Hongli
    I'm looking at integrating multipart form-data parsing in a web server module so that I can relieve backend web applications (often written in dynamic languages) from parsing the multipart data themselves. The multipart grammar (RFC 2046) looks non-trivial and if I implement it by hand a lot of things can go wrong. Is there already a good, lightweight multipart/form-data parser written in C or C++? I'm looking for one with no external dependencies other than the C or C++ standard library. I don't need email attachment handling or buffered I/O classes or a portability runtime or whatever, just multipart/form-data parsing. Things that I've considered: GMime - depends on glib, so no go. libapreq - too large, depends on APR, badly documented, no unit tests. I've also looked at writing a parser with Ragel, but I can't figure out how to do it because the grammar is not static: the boundary can change arbitrarily.

  • Weird ViewControllers - iPhone SDK

    - by Kevin
    Hello everyone, I have a Tab-Bar Application for this iPhone application I am making. I make a simple button on the 3rd view (3rd tab), and give it an IBAction to give an alert view. When I press build and go, everything works out fine. I go onto the 3rd tab, and I press my button. It simply crashes... Why is this happening? Everything I put in this 3rd tab crashes. I create a simple view controller, and write the class files to start over, but I keep getting the same errors.. Everything works fine on my first tab, where I originally got the first view controller.. P.S It also says Incomplete Implementation of Class 'ThirdViewController'. I don't know why its there.. If anyone can help me out here, i would greatly appreciate it. Kevin

  • browser cookie issue

    - by George2
    Hello everyone, In my previous understanding, for a web site, only login user of a web site (no matter what login/authentication approach is used) could have cookie as persistent identifier, so that if the user close the browser, open browser again to go to the same web site, the web site could remember the user. But I learned recently that it seems for non-login user, there could still be a cookie associated with the user (after the user close browser, and then open the browser again to go to the same web site, the web site could remember the user), and it is called browser cookie? Is that true? If it is true, who is responsible to set the browser cookie? i.e. need some coding/config at web server side, client browser configuration (without coding from server side), or both? How could web server access such cookie? Appreciate if any code samples. thanks in advance, George

  • Recommended way to remove events on destroy with jQuery UI Widget Factory

    - by user1031947
    I'm using the jQuery UI Widget Factory to build a jQuery plugin. My plugin binds custom events to the window... _subscribe: function() { $(window).on("dragger.started", function() { ... }); } I am wondering how to go about removing these events, when a particular instance of the plugin is destroyed. If I use... destroy: function() { $(window).off("dragger.started"); } ...then that will mess up any other instances of the plugin on the page, as it will remove all "dragger.started" events. What is the recommended way to go about destroying only those events that are associated with an instance of the plugin? Thanks (in advance) for your help.
