• Twitter oauth php problems

  - by Patrick Gates

  I'm writing some backend script for a twitter app and heres how it's going On the app you click a button that sends you to login.php on my server which logs into my database connects to twitter with my consumer key and secret: $to = new TwitterOAuth($consumer_key, $consumer_secret); $tok = $to->getRequestToken(); $request_link = $to->getAuthorizeURL($tok); and then writes the token and secret to the database, sets a session equal to the id in the database of the token and secret and then redirects to the "$request_link" You then go through the process of logging in and such on twitter and it redirects you to callback.php on my server Callback.php consists of logging into the database again, getting the new token and secret, and then writing the new token and secret to the database and then prompts you to go back to the app Then on the app, all I'm trying to do is access the basic credentials$to->get('account/verify_credentials') and it keeps coming back "could not authenticate you" What am I doing wrong?? Thank you for all the help :)

• Is it safe to use a subversion feature branch after reintegrate-merged to trunk?

  - by ripper234

  Must a feature branch be deleted after it's merged (reintegrated) back to trunk? I prefer to constantly merge changes back and forth from my feature branch - I believe this keeps the conflicts to a minimum. Yet I understand that once you use the reintegrate merge to trunk, a feature branch should be deleted. Is it so? Why? What can I do to circumvent this? Update I'm asking about technical problems that come from the tool, not "methodology concerns". I intend to keep working on the feature branch after the merge. Update the top answer indeed specifies a rather complex procedure (merge, delete & rebranch). Is there an easy way to accomplish this in TortoiseSVN? Shouldn't there be?

• Mvc3 IEnumerable<QuestionModel> have a List<QuestionOptionModel> property. When I post, I get null list

  - by user1649439

  There is a example here. I am trying to use this technique in a large form with a list(List) but when I post back, the Viewmodel.Order that should’ve contained list of items and activities return with the lists empty. My QuestionModel.cs like this. public int Id { get; set; } public string QuestionText { get; set; } public System.Nullable<bool> OptionType1 { get; set; } public System.Nullable<bool> OptionType2 { get; set; } public List<QuestionOptionModel> OptionList = new List<QuestionOptionModel>(); When I post back "IEnumerable questions" List OptionList comes null.

• git repository sync between computers, when moving around?

  - by Johan

  Hi Let's say that I have a desktop pc and a laptop, and sometimes I work on the desktop and sometimes I work on the laptop. What is the easiest way to move a git repository back and forth? I want the git repositories to be identical, so that I can continue where I left of at the other computer. I would like to make sure that I have the same branches and tags on both of the computers. Thanks Johan Note: I know how to do this with SubVersion, but I'm curious on how this would work with git. If it is easier, I can use a third pc as classical server that the two pc:s can sync against. Note: Both computers are running Linux. Update: So let's try XANI:s idea with a bare git repo on a server, and the push command syntax from KingCrunch. In this example there is two clients and one server. So let's create the server part first. ssh user@server mkdir -p ~/git_test/workspace cd ~/git_test/workspace git --bare init So then from one of the other computers I try to get a copy of the repo with clone: git clone user@server:~/git_test/workspace/ Initialized empty Git repository in /home/user/git_test/repo1/workspace/.git/ warning: You appear to have cloned an empty repository. Then go into that repo and add a file: cd workspace/ echo "test1" > testfile1.txt git add testfile1.txt git commit testfile1.txt -m "Added file testfile1.txt" git push origin master Now the server is updated with testfile1.txt. Anyway, let's see if we can get this file from the other computer. mkdir -p ~/git_test/repo2 cd ~/git_test/repo2 git clone user@server:~/git_test/workspace/ cd workspace/ git pull And now we can see the testfile. At this point we can edit it with some more content and update the server again. echo "test2" >> testfile1.txt git add testfile1.txt git commit -m "Test2" git push origin master Then we go back to the first client and do a git pull to see the updated file. And now I can move back and forth between the two computers, and add a third if I like to.

• How to use SSRS to retrieve HTML snippets with embedded images the easy way

  - by Ram

  I have a web-app that retrieves reports from our SSRS server dynamically - we hit a URL and out pops some HTML4.0 which I stuff into a div for the user to view. I recently tried adding a report that has an embedded image (in the RDL itself) and the image doesn't make it through. What does make it through is an IMG SRC reference back to the SSRS box but we do not allow end users to hit the SSRS box directly... users query the web-app and the web-app interacts with the SSRS service. There is an option to render in MHTML (note that we typically use rs:command=RenderHTML with rs:format=HTML4.0) - the blob returned appears to be valid MIME but does not seem friendly for stuffing into a DIV... am I missing something obvious? My next step is to parse the MIME, swizzle the references and stuff the whole thing back into the page but I feel like this is the hardway. What is the easy way to retrieve HTML snippet reports out of SSRS with embedded images?

• Android service puts multiple instances of an activity in the history

  - by HenryAdamsJr

  I'm making a music player. When you press play, it loads a notification into the OnGoing section. When you go anywhere else in the system, I want the music to keep playing. All of this is fine. The problem is that when I relaunch my activity from the Notification, it adds a task to the history stack each time, so if I hit back, I have to see the instance of Activity B from where I pressed play, and from every time I clicked on the notification to go back to Activity B. I want the instance of Activity B that I launch from the notification (via the service) to be the only copy of that Activity in the history. I've been playing around with various Intent flags and Activity attributes in the manifest, but I haven't found the proper combination.

• Is it stable to change I/O direction on microcontroller repeatedly?

  - by SS

  I'm new to microcontroller programming and I have interfaced my microcontroller board to another device that provides a status based on the command send to it but, this status is provided on the same I/O pin that is used to provide data. So basically, I have an 8-bit data line that is used as an output from the microcontroller, but for certain commands I get a status back on one of the data lines if I choose to read it. So I would be required to change the direction of this one line to read the status thus converting this line as an ouput to an input and then back to an output. Is this acceptable programming or will this changing of the I/O pin this frequently cause instability? Thanks.

• Doing a lot of input validation in VB.NET

  - by Andy

  I have a form set up where users can enter their booking for a room at my college. I want to validate the user input to avoid SQL injection (my program uses a MS Access database) and also stop numbers and synbols in their name, etc. I can do the validation fine, but there is to be a lot of validation and then methods executed only if all validation tests come back as true. I did have something like this: If txtName.Text = "" Then frmBookErr.SetError(txtName, "Name field cannot be left blank.") fail = 1 Else frmBookErr.SetError(txtName, "") fail = 0 End If And then check the fail variable, but it obviously gets overridden later in the form if one of the validation tests come back as true. Can anyone provide some input into this? Thanks.

• Redirect to prevent dup submission...but then you loose existing data

  - by coffeeaddict

  Here's the scenario User is on your checkout.aspx page Somewhere in the process, when clicking the pay button, you redirect the user to an intermediate page (before the confirmation page) to do some other logic. That intermediate page performs whatever logic based on a querystring flag you sent with the redirect from the checkout page This intermediate page also serves as an error page. So if any logic in the intermediatePage.aspx.cs fails I'm setting a message to be displayed on this page to the user If I refresh, that querystring value is still in the url..hence when it hits my Page_Load again, then the server-side logic is called & run again and I don't want this to happen The avoid this behavior/problem, the logical next step is to do a redirect back to the same page if they refresh (not sure how you'd catch that) to get rid of that querystring But when you redirect back to the same page your error message is gone, lost in the redirect therefore you end up showing them the same page but all values for the error message are now gone I do not want to solve this with Javascript either. I am not sure the best way to handle this.

• x86 and Memory Addressing

  - by IM

  I've been reading up on memory models in an assembly book I picked up and I have a question or two. Let's say that the address bus has 32 lines, the data bus has 32 lines and the CPU is 32-bit (for simplicity). Now if the CPU makes a read request and sends the 32bit address, but only needs 8 bits, all 32 bits come back anyway? Also, the addresses in memory are still addressed per byte correct? So fetching one byte would bring back 0000 0001 to address 0000 0004? Thanks in advance

• Having onFocus do several things.

  - by Jakob

  So I have this input tag <input ... onFocus=...> and what I want is for a warning popup to come up if somebody clicks to write in the input field. After the person has read the warning he/she closes the popup and can continue to write in the field. I have managed to implement the popup just fine but my problem is that I lose focus on the input field when the popup comes up so the next time I click the field the popup comes back again and im back on square one. The system I work on uses php and javascript so and I cannot use anything other than that to solve the problem and my experience with both php and javascript is limited.

• Retrieve value of one column in a table

  - by user327094

  Here is my problem: I have 2 tables Accounts and Transaction Logs. in Accounts table, it has column "Amount" which is a base amount of an account. and in Trans Logs table, it also has column "Amount" which is additional (add or minus to the base amount) amount of the account. and I don't know how to retrieve that base amount to edit it, then save it back to the table. That means I need to get a value of the right column by using Acc_No to find. I'm using DataSet, by the way. i think it should go like this: Dim Amount as Decimal Amount = *the code to retrieve the base amount* Amount = Amount + txtAmount.Text *the code to save the new amount back to Accounts table* Thank you!

• What conditions cause a web browser to display the "Page Expired" message?

  - by RichardHowells

  I assumed that sending a page out with an expiry (a la)... Response.Cache.SetExpires(System.DateTime.Now.AddSeconds(5)); Response.Cache.SetCacheability(HttpCacheability.Public); Response.Cache.SetValidUntilExpires(true); ...would mean that if the user hit the back button they would see the expired page. It does not seem to work that way. I found that using the back button would simply show the old (IMO expired) page. In fact in experimenting with different combinations of caching/not caching and expiry times I NEVER managed to get the "Page Expired" message out of the browser. What conditions provoke that message? Server Environment ASP .Net. I've only tested in IE8 - I'm assuming that other browsers are consistent here.

• Ideal way/architecture to deliver large data over Web Services

  - by zengr

  We are trying to design 6 web services, which will serve another client component. The client component requires data from the web service we are implementing. Now, the problem is, there is not 1 WS we are implementing, there is one WS which the client component hits, this initiates a series (5 more) of WSs which gather data from their respective data stores and finally provide the data back to the original WS, which then delivers the data back to the client component. So, if the requested data becomes huge, then, this will be a serious problem for our internal communication channel. So, what do you guys suggest? What can be done to avoid overloading of the communication channel between the internal WS and at the same time, also delivering the data to the client component.

• What is the best way to restore(rollback) data in an application to a specified state(date) ?

  - by panzerschreck

  Hello, An example would set the context right, the example below captures the various states of the entity, which needs to be reverted(rolled back) . State 1 - Recorded on 01-Mar-2010 Column1 Column2 Data1 0.56 State 2 - Recorded on 02-Mar-2010 Column1 Column2 Data1 0.57 State 3 - Recorded on 03-Mar-2010 Column1 Column2 Data1 0.58 User notices that state3 is not what he intended to be in, decides to revert back to state2. One approach that I can think of, without modifying the entity is via "auditing" all the inserts/updates, as below, the rollback information captures the data just before the updates/modifications on the entity, so that it can be applied in an order when you need to revert.Please note that changing the entity's schema, is not an option. Rollback - R1 recorded on 01-Mar-2010 Column1 Column2 Data1 0.56 Rollback - R2 Recorded on 02-Mar-2010 Column1 Column2 Data1 0.56 Rollback - R3 Recorded on 03-Mar-2010 Column1 Column2 Data1 0.57 So, to get to state2 , we would start with rollback information R1,apply R2 onto it. Is there a better approach to achieve this ? Thanks for your time.

• imageview draw issue with asynctask

  - by alexb

  Have the following asynctask that i'm using to download some images. Works fine except for the very first image, which doesn't always appears unless I do something like move to the next image and then back again. public class DownloadImageTask extends AsyncTask { static ImageView _imageView=null; public DownloadImageTask(ImageView ctl){ _imageView=ctl; } protected void onPostExecute(Bitmap result) { _imageView.setImageBitmap(result); } ... } I thought this might be an issue with updating the UI on a background thread, so I reworked this using an abstract class that invokes a method on the UI thread that calls .setImageBitmap() but I still get the same behaviour - works fine for all images except the first, unless I move to the next image and back again. Is there a way to force a redraw on the imageview after i set the image?

• Dynamic added elements double effect after page transition

  - by Emil Moe

  I have added dynamic from jQuery in my code, but when I go back one page and return to the page where the 's are added and you press them, they somehow click twice now. I have tried with an alert('something'); when I click: $(document).on('click', '#products a', function() { alert('something'); } And it's shown twice when you return to the page. I have tried $('#products a').remove(); When you click the 'Back' button, because I thought all elements where added twice, but that made no difference. I don't have anything around these lines, maybe I need $(document).ready(); or something with pageinit?

• Android TranslateAnimation resets after animation

  - by monmonja

  I'm creating something like a SlideDrawer but with most customization, basically the thing is working but the animation is flickering at the end. To further explain, I got an TranslateAnimation then after this animation it returns back to the original position, if i set setFillAfter then the buttons inside the layout stops working. If i listen to onAnimationEnd and set other's layout to View.GONE the layout fickers. Judging from it is that on animation end, the view goes back to original position before the View.GONE is called. Any advice would be awesome. Thanks

• Can I save my app's state at close time in iPhone OS?

  - by Steve

  I have an app that functions much like an ebook. I have a bunch of textual information in various languages that is accessible through a number of drill down methods. When a user wants to get into where they were reading last, they currently have to navigate through the section and chapter menus to get back to where they were. An ideal solution for this would be to setup a bookmark system, which I am considering. But if I remember correctly, when iPhone OS 4 was announced, they seemed to make a big deal of the added ability to save the state of an app. Does that mean that someone using my reader app would be able to just exit right out, do whatever, and then when they came back in, it would be the reading screen just as they left it? I don't know much about how to setup a bookmarking system, I suppose it would be worth investigating, but I would probably want to just hold off for iPhone OS 4 if that is indeed what it will be capable of doing. Any thoughts or insights would be appreciated!!

• Are string resource ID values guaranteed to be consistent over different projects?

  - by jax

  I have some messages being passed back from my server through php. The problem is that the messages are in English and if the user is using another language they will still get the message in English. So I had an idea that maybe instead of passing back the message I would instead pass the String resource Id from the android app, that way the app will get the correct string id for their language. I will use this in a number of apps so I just want to know if the string id is guaranteed to be the same across different android projects?

• Git: How do I rewind the Master branch on the remote origin

  - by user277260

  I made 5 commits to Master branch when bug hunting on a private project and pushed them to the remote origin (my own private vps). Then I saw that commits 4 and 5 were going to cause trouble elsewhere and I need to undo them, so I checked out commit 3 again, made a new branch "Dev" from that point, and did a few more commits fixing the issue properly. Then I did git reset --hard HEAD~2 on Master to pull it back to the point that I branched Dev. Then I did git merge to fast forward Master back to the end of the Dev branch. So now I have a local repository, with Dev and Master both pointing to the same, up to date version of the project with the latest bug fix. Problem is, when I try to push the project now to the origin, it fails and gives me an error message: ! [rejected] master - master (non-fast forward) error: failed to push some refs to 'myserver...myproject.git' What have I done wrong, and how do I fix it? Thanks
