• SSRS Performance Mystery

  - by user101654

  I have a stored procedure that returns about 50000 records in 10sec using at most 2 cores in SSMS. The SSRS report using the stored procedure was taking 20min and would max out the processor on an 8 core server for the entire time. The report was relatively simple (i.e. no graphs, calculations). The report did not appear to be the issue as I wrote the 50K rows to a temp table and the report could display the data in a few seconds. I tried many different ideas for testing altering the stored procedure each time, but keeping the original code in a separate window to revert back to. After one Alter of the stored procedure, going back to the original code, the report and server utilization started running fast, comparable to the performance of the stored procedure alone. Everything is fine for now, but I am would like to get to the bottom of what caused this in case it happens again. Any ideas?

• 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.

• AudioTrack skipping after pause and resume

  - by Markus Drösser

  Hi, here is the problem. I play a wav file that i recorded earlier without problems. but when i call audiotrack.pause() and audiotrack.start() again after some waiting, it skips some frames of the file. why is that? here is my play listener // Start playback audioTrack.setPlaybackPositionUpdateListener(new OnPlaybackPositionUpdateListener() { @Override public void onPeriodicNotification(AudioTrack track) { try { if(ramfile!=null && ramfile.read(buffer)==-1) { audioTrack.release(); audioTrack = null; ramfile.close(); playing=false; } else { audioTrack.write(buffer, 0, buffer.length); } } catch (IOException e) { try { ramfile.close(); playing=false; } catch (IOException e1) { } } } @Override public void onMarkerReached(AudioTrack track) { playing=false; track.release(); } });

• problem with application after moving from local to hosting server

  - by marcin_koss

  I have an application developed with CodeIgniter that works perfectly on my local server. After uploading it to the hosting server I've run into few issues that I can't figure out. I removed the index.php from URL by changing $config['index_page'] = "" in config.php file and adding rewriterule in .htaccess file. Everything worked fine on a local server. On hosting server the webstie wouldn't load until I reverted those changes to defaults. Now the strangest thing. I test the website and all pages load fine except of one. When I point to that page the browser responds with "Connection closed by remote server" (That's from Opera, other browser gave similar response). After closing the browser when I try to load the website again, now it won't even load any page showing me CodeIgniter's styled error "404 Page Not Found" What he heck?

• Struts1 and Spring wiring question

  - by Dev er dev

  Recently I had a pleasure of working again on Struts 1.1 application. It uses Spring 2.5, but not for actions. I would like to hook it up to use Spring as DI for Struts Actions also, as it would make my life a loot easier. I found out DelegatingRequestProcessor could be used for this purpose, at least according to documentation, but seems it has been deprecated as of Spring 3.0. Switching to the new version of Struts is not an option. Does anyone have better idea then starting to use deprecated stuff?

• Can a shell loop unzip all the files in a directory?

  - by helpwithshell

  I've seen loops to unzip all zip files in a directory. However, before I run this, I would rather make sure what I'm about to run will work right: for i in dir; do cd $i; unzip '*.zip'; rm -rf *.zip; cd ..; done Basically I want it to look at the output of "dir" see all the folders, for each directory cd into it, unzip all the zip archives, then remove them, then cd back and do it again until there are no more. Is this something I should do in a single command or should I consider doing this in Perl?

• autosave pattern

  - by Mark

  I'm using localstorage to do gmail-style autosave on a webpage. So I basically save every 30 seconds to local, OK. The problem is recovery. I can't detect whether or not a user has crashed or incorrectly exited. So let's say the user crashed and loads up the form again, I can't just continue saving and overwriting the previous autosaves. I need to restore the previous save. But let's say the user didn't crash. He did everything correctly, but then used a different browser to edit the same file, so no new data to the previous browser's localstorage. He then loads up the file in the previous browser. The localstorage should not be restored in that case. Assuming there's no way to compare timestamps, how can I solve this problem? Thanks.

• AsyncTask won't stop even when the activity has destroyed

  - by Raja

  Hi all, I have an AsyncTask object which starts executing when the activity is created and does stuff in the background (downloads upto 100 images). Everything works fine but there is this peculiar behavior which i'm not able to understand. For eg: when the android screen's orientation changes then the activity is destroyed and created again. So I override the onRetainNonConfigurationInstance() method and save all the downloaded data executed in the AsyncTask. My purpose of doing this is to not have AsyncTask run each time activity is destroyed-created during orientation changes, but as i can see in my logs the previous AsynTask is still executing. (The data is saved correctly though) I even tried to cancel the AsynTask in the onDestroy() method of the activity but the logs still show AsynTask as running. This is really strange behavior and would really be thankful if someone can tell me the correct procedure to stop/cancel the AsynTask. Thanks

• Any valid use of goto in PHP?

  - by nikic

  I know, there are other questions about the goto statement introduced in PHP 5.3. But I couldn't find any decent answer in there, all were of the type "last resort", "xkcd", "evil", "bad", "EVIL!!!". But no valid example. Only statements that there aren't any uses. Or statements that there are some rare use cases (again, without examples). So, the question is: "Which are the valid uses of goto in PHP". Answers for "Is goto evil" are not welcome and will get downvoted. Thanks :) Or does somebody have a link to an RFC where the decision is explained - I couldn't find one.

• Registry based components with Inno Setup

  - by cyxou

  Hello guys! I'm creating an application for my company. And the goal is to create a universal installer that will be checking user's registry for specific apps installed and according to these apps would create a list of available installation components in "Select Components" window. And that's the particular problem I'm stacked with. I've already created the installer, but a user have to check/uncheck components he doesn't need because he doesn't use specific app. That is definitely not a good way of doing thing I guess... So I'm asking for help, please. Could this be implemented through "Select Components" window and how or I should create custom wizard page with checkboxes (again - How)? Many thx in advance.

• Shouldn’t GridView’s RowStyle-HorizontalAlign property overwrite CSS’s text-align property?

  - by AspOnMyNet

  a) As far as I know, GridView’s RowStyle-HorizontalAlign property should overwrite CSS’s text-align property, and thus text inside GridView's cells should be located on the left side of the cells, but is instead moved to the right side. Why is that? b) Similarly, RowStyle-Font-Bold should overwrite CSS’s font-weight property and thus fonts shouldn’t be in bold. But again, CSS’s property overwrites RowStyle’s Font-Bold property. Why? <div id="someClass"> <asp:GridView ID="gvwShowUsers" runat="server" > <RowStyle BackColor="#FFFBD6" ForeColor="#333333" Font-Bold="false" HorizontalAlign="Left" /> <Columns> <asp:BoundField DataField="UserName" HeaderText="UserName" /> </Columns> </asp:GridView> </div> CSS file: #someClass td { font-weight:bolder; text-align:right; } thanx

• How to complete a git clone for a big project on an unstable connection?

  - by LaPingvino

  I am trying to git clone the LibreOffice codebase, but at the moment I have an internet connection by mobile phone of about 300kbps and it's just anything but stable. I can get the connection back any moment, but then the git clone process already stopped working, and no way to get it running again. Is there some way to have a more failure-resistant git clone download? One option I considered myself is to download someone else's .git directory, but that is overly dependent of others and doesn't seem like the best possible solution to me.

• .BAT Switches Parsing

  - by giiYanJ

  Erm.. I'm working with a switches parsing in BAT files, which goes like this: <commands> -a -b -x -y -z -u abc ...... The user may input a lot of switch, or none. So I used looped shift to make parsing infinite switches possible: :loop IF "%1"=="-a" ... SHIFT GOTO loop But when the script ends, I always get cmd executing the switches and showing up error like '-n' is not recognized as an internal... So, someone got any idea? Thanks a lot... P/S: Make solution sticks with BAT script if possible as using other language may cause dependencies problem as this script is aimed on ANY computer with Windows. Finally, thanks again =) EDIT: Tried shf301 suggestion, i found out that I used DEL %0 to delete itself but it seems the %0 is shifted into the arguments because of the SHIFT command.

• Changing window focus on OS X

  - by MatsT

  As part of an InstallationCheck script on OS X I need to use finder dialogs to let the user browse for files. When I'm done I want to move the installer application up front again so that the user can easily continue with the installation. I have already tried the simple: tell application "Installer" to activate This does not work because as long as I am inside the script the Installer application is unresponsive and when i try to activate it the applescript will try to wait until Installer responds, effectively locking the program until the InstallationCheck script times out. So basically I need a way to focus an application that works even if it is currently unresponsive. Is there any way to do this either from an applescript or directly from the perl script?

• Google Play: how dev can give (already purchased) app to customer as a gift?

  - by Tertium

  Yes, SO, I know, it's not a "programmer's" question:) But customers sometimes help us (devs) with our code, so we (devs) shold be grateful. I think answer to my question will be useful for all fellow android devs. User has purchased my app. Refund period (15min) is over of course. Now I'd like to return money to him as a gift, because he helped me in testing a little. If I refund the entire order in Checkout-Orders will user keep my app 'purchased'? I mean will he be able to uninstall and install it again from GooglePlay-MyApps and will app be marked "purchased"? Will Google LVL accept him to run the app? I've done such refunds before, but then they called it "Android Market", and refund was 12h, and there were no LVL. Maybe somebody know another way to make a small gift using Google Play?

• Require help with program for edutainment game

  - by Ender

  I am working on a factorisation problem and for small numbers it is working well. I've been able to calculate the factors (getting the answers from Wolfram Alpha) for small numbers, like the one on the Wikipedia page (5959). Along with the Wikipedia page I have been following this guide. Once again, as my Math knowledge is pretty poor I cannot follow what I need to do next. EDIT: It finally works! I'll post the working code up here once I've got it fully working so that others in my predicament can learn from it.

• How do you increase Internet Explorer 7's "Select as you type" timeout for comboboxes?

  - by Iain Fraser

  In Internet Explorer 7, you can select options from comboboxes by typing the first few letters of the value you're looking for. However, some people in our organisation are a bit slow and can't type their selection quick enough, with the result that the timeout is triggered and the "select as you type" process starts all over again. Example: If I type A-R-M-A (looking for Armadale) then wait half a second and type D, I'll get selections beginning with the letter D. What I want to do is increase this timeout to allow for slow typers. (We're in a corporate environment so rolling out these changes to all machines won't be a problem).

• Is it possible to talk to the iPhone simulator/device.

  - by Plumenator

  I need to automate the build/deploy process for my iphone applications from a script. I can use xcodebuild to build the project, then use Applescript to deploy and debug/run the application. Assuming the application will stop by itself after a while, I need to collect the generated logs for verification. But the problem is I have no way to know when the application ended from outside of the application itself. If the running time is fixed, I can again use Applescript to stop the application (Cmd+Shift+Enter). So there has to be a way to connect to the device/simulator and wait on the application somehow.

• Crystal Report | Printing | Default Printer

  - by Akshay J

  I am making one application where user will print invoices which I am displaying using Crystal Report. The user showed me his current application made using ForPro. In that application, under Printer Options form, one can see all the printers currently installed and the user could select default printer. When the invoice is made, the user presses the print button, then there is one dialog asking for no. of copies. When it's entered, the invoice gets printed directly, without any Print Dialog Box. If the user wants to change the printer again he/she will change it in the Printer Option form. I want to know if similar thing is possible in Crystal Report and need guidance on how to approach for it.

• Rails view error "invalid byte sequence in US-ASCII" error after upgrading Ruby to 1.9.2

  - by Jon

  Running Rails 2.3.9 and just upgraded to Ruby 1.9.2p0. I have been putting: # encoding: utf-8 in a bunch of my .rb files where ever "£" character is used, and this seems to be working. But i just got my first view error: invalid byte sequence in US-ASCI for this line of code: <%= number_to_currency(product.price, :unit => "£", :precision => 0) %> I don't think its a coincidence that the "£" character is involved again. Any ideas on how to solve this please? Thanks

• Creating objects and referencing before saving object to db

  - by Flexo

  Sorry about the vague title, but i didnt know how to ask the question in one line :) I have an order with nested itemgroups that again have nested items. the user specify the amount of item that he would like to have in each itemgroup. I would like to create these items in the create method of the orders controller when the order itself is being created. I kinda have 2 problems here. First, how do i set the reference of the items, or better yet, put the items into the @order object so they are saved when the @order is saved? the items are being stored in the db as the code is now, but the reference is not set because the order is not stored in the db yet so it doesnt have an id yet. Second, im not sure im using the correct way to get the id from my itemgroup. @order = Order.new(params[:order]) @order.itemgroups.each do |f| f.amount.times do @item = Item.new() @item.itemgroup_id = f.id @item.save end end

• Which character is first among 4 characters in c++

  - by Ashiqur Rahman

  In my project I take a string from user and then I need to check if vowels a, e, I, O, U are present. If so, I have to find out which one comes first in the string and which one comes next after that. For example, if a user gave input something like this: char expr[] = "this is for something real"; I comes first, then I again, then O and so on. I checked whether the characters are in the string or not using strchr(expr,'character here'). To find which character comes first, I find the index of each character using const char *ptr = strchr(expr, characters here); if(ptr) { int index = ptr - expr; } After that I check which index is bigger. But this is very long process. Is there a smarter way to do this?
