• How can I pass a raw System.Drawing.Image to an .ashx?

  - by Mike C

  I am developing an application that stores images as Base64 strings in xml files. I also want to allow the user to crop the image before saving it to the file, preferably all in memory without having to save a temp file, and then delete it afterwards. In order to display the newly uploaded image, I need to create a HTTP handler that I can bind the asp:Image to. The only examples for doing this online require passing the .ashx an ID and then pulling the image from a DB or other data store. Is it possible to somehow pass the raw data to the .ashx in order to get back the image? Thanks, Mike

• Wrap text around a right-aligned icon?

  - by user246114

  Hi, Is it possible to make a small box (which will be a row element in a list for me) with an icon in the upper right corner, and text wrapped around it? Something like: ------------------------------------------------- | Some text here which may wrap around [icon] | | if it were to get too long, but then fit well | | around the icon in the upper right corner? | ------------------------------------------------- I was going to use this as a row in a list, and the user could click the icon in the upper-right to delete the row. I could use either a <div> or a <table>, I'm not sure which will be better?: <div> <p>The text</p> <img src="close.png" align="upper-right"> </div> Thanks

• How to optimize erasing from multimap

  - by Dominating

  I have two multimaps defined so multimap phoneNums; and multimap numPhones; they are some kind of phone registry - phoneNums contains Key name, and second argument phonenumber, numPhones contain Key phonenumber and second is name. I want to optimize erase from both of them when i want to delete string Key form phoneNums, which is also second element in numPhones. When i enter data it is entered in both multimaps so they are actually the same but with swapped first and second when i put it on tests it says that erasing is too slow - N*N and must be only N cin>>stringToErase; phoneNums.erase(stringToErase); multimap<string, string>::iterator it; multimap<string, string>::iterator tmpr; for(it = numPhones.begin(); it != numPhones.end();it++) { if(it->second == tringToErase) { tmpr = it; numPhones.erase(it,tmpr); } }

• Django save, column specified twice

  - by realshadow

  Hey, I would like to save a modified model, but I get Programming error - that a field is specified twice. class ProductInfo(models.Model): product_info_id = models.AutoField(primary_key=True) language_id = models.IntegerField() product_id = models.IntegerField() description = models.TextField(blank=True) status = models.IntegerField() model = models.CharField(max_length=255, blank=True) label = models.ForeignKey(Category_info, verbose_name = 'Category_info', db_column = 'language_id', to_field = 'node_id', null = True) I get this error because the foreign key uses as db_column language_id. If I will delete it, my object will be saved properly. I dont quite understand whats going on and since I have defined almost all of my models this way, I fear its totally wrong or maybe I just missunderstood it... Any ideas? Regards

• Can't Add LINQ to SQL classes to projects in VS2010

  - by MisterJames

  I just ran into something in Visual Studio 2010 RC that wasn't previously happening (like, yesterday). No software changes here, but I did run into some muck yesterday when compiling that required a reboot. I am unable to add LINQ to SQL classes to any project through the add dialog. I have created ASP.NET web sites, ASP.NET MVC projects - both of these as 'templated' and as 'empty' - and there appear to be no templates installed or available. I have made sure that the project targets the 4.0 Framework. I can easily add a new database and the ADO.NET entity framework templates are there. As a workaround I can copy a DBML file to my project, delete all tables and sprocs, update the connection string and use the leftover shell (the designer works fine like this), but it's a pain. Has anyone else had their templates drop? Figured out how to reinstall them?

• Git strange behaviour

  - by pocoa

  git status # On branch master # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: readme.txt # modified: requirements.txt # no changes added to commit (use "git add" and/or "git commit -a") I didn't make any changes on those files. But I'm getting this message even if I try: git checkout -- readme.txt git checkout -- requirements.txt When I run: git diff it shows the whole file as updated. But the contents are the same. I tried to delete them and checkout again, but it didn't work.

• AS2 acts randomly when changing scenes on the first frame

  - by fabieno

  I have a flash movie containing to scenes: scene1, scene2. I have chosen the order so that scene1 starts first, I was requested to add a functionality to allow flashvars to be passed, if fv_change equals one then scene2 should be the first to appear when the movie is loaded. I have included the following code in scene1 first frame of some layer: this.onEnterFrame = function() { delete this.onEnterFrame; if (isset==undefined && _root.fv_change && _root.fv_change==1) { isset = true; gotoAndStop("scene2",1); } } when testing in my flash environment everything worked fine, when I exported it to an HTML & SWF combo I got random results, I refreshed the page several times and some of the times scene2 appeared and some of the times it stayed with scene1. Am I doing something wrong? what is the correct way to change scene order using AS2 and external data(flashvars for that matter).

• Image rendering on browser or temporary images?

  - by Muralha

  I'm trying to make a statistics page where it will show several data and charts. The charts need to be pictures so that the user can save it/drag-and-drop to his/her personal reports. I'm using Gruff Graphs for Ruby to produce the charts but I don't know the best way to display the results safe and protected. Some of my ideas/tries are: save the chart to a file (jpg, png)? problem: data is available to anyone (don't have access to cron, to delete data from time to time) render in the browser (has to work on IE)? Use javascript (Raphaël—JavaScript Library) or Google API and output a PDF report (need plugin or gem, right)? use send_data? i've tried to output other way than inline, because I needs to show other data, is it possible? Thanks for any help.

• windows I/O manager - IRP's classification in read-like and write-like

  - by clyfe

  I am writing a windows filesystem minifilter driver that must fail IRP's in a preoperation callback. How can I find out from the callback parameters if the operation is read-like ( only reads data ) or it's write-like ( modifies data on the disk - write, delete etc ) ? I'm thinking on: Data->Iopb->TargetFileObject->ReadAccess Data->Iopb->TargetFileObject->WriteAccess But I'm not sure, I think thees are available only in postoperation callback. The documentation is really cumbersome. Code sample: FLT_PREOP_CALLBACK_STATUS Fail ( __inout PFLT_CALLBACK_DATA Data, __in PCFLT_RELATED_OBJECTS FltObjects, __deref_out_opt PVOID *CompletionContext ) { FLT_PREOP_CALLBACK_STATUS status = FLT_PREOP_SUCCESS_NO_CALLBACK; if ( IS WRITE_LIKE(Data, FltObjects) ) { // ??? HOW DO I FIND OUT???? if( FLT_IS_FASTIO_OPERATION(Data) ){ status = FLT_PREOP_DISALLOW_FASTIO; } else { status = FLT_PREOP_COMPLETE; } Data->IoStatus.Status = STATUS_ACCESS_DENIED; Data->IoStatus.Information = 0; return status; } return status; }

• Self-extracting Delphi program

  - by Steve

  I'm writing an updater program in Delphi7 which will be run once, but needs many files to run. What I'd like the achieve: 1, User runs exe 2, Exe unpacks files, runs updater 3, If updater detects and error, prompts the user to send log in e-mail 4, After the updater is run, temporary files are deleted (some of these files are dlls used by the updater program, so the updater has to be closed before the files can be deleted) Can anyone recommend a good solution? I've thought about using Inno Setup (too complicated for such an easy task) or using a self-extracting zip file (but how to delete the files afterwards)? Thanks!

• IE 8 Caching Problem

  - by Jeff Catania

  One of my javascript sources had an extra comma that was throwing an error in IE8. So I opened up my editor, deleted the comma, and saved. I reloaded IE8, but it was still pulling the old js file. I deleted everything in "Delete Browsing History...", and restarted the browser. It is still pulling the old file. I even set up a log on my server to show whenever the js file was requested. When reloading with IE, the js file is never requested. I tried doing the same process in Chrome and FF, and it pulled the new file and logged properly on the server. Is there some other cache that I am failing to clear in IE that would cause this problem?

• Whats wrong with this task queue setup?

  - by Peter Farmer

  I've setup this task queue implementation on a site I host for a customer, it has a cron job which runs each morning at 2am "/admin/tasks/queue", this queues up emails to be sent out, "/admin/tasks/email", and uses cursors so as to do the queuing in small chunks. For some reason last night /admin/tasks/queue kept getting run by this code and so sent out my whole quota of emails :/. Have I done something wrong with this code? class QueueUpEmail(webapp.RequestHandler): def post(self): subscribers = Subscriber.all() subscribers.filter("verified =", True) last_cursor = memcache.get('daily_email_cursor') if last_cursor: subscribers.with_cursor(last_cursor) subs = subscribers.fetch(10) logging.debug("POST - subs count = %i" % len(subs)) if len(subs) < 10: logging.debug("POST - Less than 10 subscribers in subs") # Subscribers left is less than 10, don't reschedule the task for sub in subs: task = taskqueue.Task(url='/admin/tasks/email', params={'email': sub.emailaddress, 'day': sub.day_no}) task.add("email") memcache.delete('daily_email_cursor') else: logging.debug("POST - Greater than 10 subscibers left in subs - reschedule") # Subscribers is 10 or greater, reschedule for sub in subs: task = taskqueue.Task(url='/admin/tasks/email', params={'email': sub.emailaddress, 'day': sub.day_no}) task.add("email") cursor = subscribers.cursor() memcache.set('daily_email_cursor', cursor) task = taskqueue.Task(url="/admin/tasks/queue", params={}) task.add("queueup")

• Git ignore file for vb.net projects

  - by John C

  Placing a vb.net project under git control in windows (was previously under VSS - long sad story of repository corruption, etc). How should I set up the ignore file? The exclusions I'm thinking of using are: *.exe *.pdb *.manifest *.xml *.log (is git case sensitive on windows? Should I exclude *.Log as well?) *.scc (I gather these were left over from VSS - maybe I should delete them?) Is this a sensible list? Should I be excluding directories?

• Quick / Built-in method for detecting table change in SQL Server?

  - by the-locster

  Is there a quick and easy way of telling if a table has changed in SQL Server? (I'm using SQL Server 2005). Something like an incrementing ID somewhere that updates on each INSERT, DELETE or UPDATE that I can keep track of. I noticed there is a sys.objects.modify_date column for each table, but I don't think it's quite what I want because the docs say: Date the object was last modified by using an ALTER statement. If the object is a table or a view, modify_date also changes when a clustered index on the table or view is created or altered.

• ActiveMQ - Removing queues programatically

  - by Eduardo Z.

  Fellow StackOverflowers, is there a way for me to remove a queue or a topic in ActiveMQ programatically? I am using ActiveMQ's standard persistency, and my application requires that, on startup, all new queues be dynamically re-created (unless there are messages stored in the queue, in which case, the queue should remain to exist). I am also creating all queues programatically through sessions. Is there an equivalent to that procedure, only to delete a queue? Querying and iterating through the existing queues would also be useful, but i haven't found a way to do that yet. Please help an ActiveMQ noob! =)

• Textmate bundle to remove a directory and build with Jekyll

  - by m1755

  I am looking for a simple Textmate bundle that will do the following two tasks in order: Delete the entire contents (including folders) of a directory (eg. ~/Sites/my_site). Run the jekyll command in the directory of the Textmate project. I am going to associate this with a "save current file" and use it to auto build my Jekyll site into the specified directory each time I save a file inside the project. Notes If #2 isn't possible, then cd into a specified directory and run the jekyll command. Would prefer bash or ruby.

• Sugar CRM integration with Java - How to add relationship

  - by Arun P Johny

  Hi, I'm trying to integrate Sugar CRM with one of my projects. I'm using Apache Axis as my SOAP client. I've created the Sugar CRM client Stub classes using Apache Axis. I'm able to login and add Leads, Opportunities, Accounts and Contacts. But I'm unable to add a relation ship between my Account and Opportunity. I've found following method in the SugarsoapPortType port.set_relationship(session, module_name, module_id, link_field_name, related_ids, name_value_list, delete) but I cannot understand the different parameters required by this method. Most of the online documents suggests a simple way as given below $result = $client->call('set_relationship',array("session"=>$session _id,array("module1"=>"Emails","module1_id"=>"<module1_id>","module2"=>"Accounts","module2_id"=> "<module2_id>"))); how can I achieve this using Java Thanks

• How does SQL Server treat statements inside stored procedures with respect to transactions?

  - by Sleepless

  Hi All! Say I have a stored procedure consisting of several seperate SELECT, INSERT, UPDATE and DELETE statements. There is no explicit BEGIN TRANS / COMMIT TRANS / ROLLBACK TRANS logic. How will SQL Server handle this stored procedure transaction-wise? Will there be an implicit connection for each statement? Or will there be one transaction for the stored procedure? Also, how could I have found this out on my own using T-SQL and / or SQL Server Management Studio? Thanks!

• [Unsolved] RowsDeleting event doesn't fire

  I have a gridview with a onrowdeleting="SellersGridView_RowsDeleting" switch.

I tried to change the first line to Response.Redirect("foo") just to check if the event itself is fired, and it turns out that it doesn't. I can't get The reason.

• Remove certain keys from a dictionary in python

  - by Margaret

  I'm trying to construct a dictionary that contains a series of sets: {Field1:{Value1, Value2, Value3}, Field2{Value4}} The trouble is, I then wish to delete any fields from the dictionary that only have one value in the set. I have been writing code like this: for field in FieldSet: if len(FieldSet[field]) == 1: del(FieldSet[field]) But receive the error "RuntimeError: dictionary changed size during execution". (Not surprising, since that's what I'm doing.) It's not the be-all and end-all if I have to knock together some sort of workaround, but is it possible to do this?
