• Removing the image from an IKImageView

  - by Brian Postow

  I have an IKImageView that is coming up effectively un-initialized. This is happening effectively in an error-state (The user is unregistered) so I haven't had a chance to put an image in it yet. In 10.6, this comes up fine, with a black rectangle. In 10.5, however, it comes up with garbage. some rectangles of noise, some rectangles of copies of the desktop, etc. I've tried setting the ZoomFactor to 0.0, I've tried setting the image to nil, but it appears that the problem is beyond that. any ideas? (My next kludge is going to be to ship tiny blank image with the app, and try to get it to load that... but that's kind of silly)

• DoDragDrop disables MouseMove Events

  - by stefan.at.wpf

  After having started a Drag & Drop operation by DragDrop.DoDragDrop(...) no more MouseMove Events are fired. I even tried AddHandler(Window.MouseMoveEvent, new MouseEventHandler(myControl_MouseMove), true); where the last parameter means I even opt in for handled events. No chance, seems like the MouseMove Event is never fired at all! Any way to still get MouseMove Events while using Drag & Drop? I'd like to Drag & Drop a control, while dragging this control it shall follow the mouse pointer. Any idea how to do this in this case?

• How are .NET 4 GUIDs generated?

  - by mafutrct

  I am aware of the multitude of questions here as well as Raymond's excellent (as usual) post. However, since the algorithm to create GUIDs was changed apparently, I found it hard to get my hands on any up-to-date information. The MSDN seems to try and provide as few information as possible. What is known about how GUIDs are generated in .NET 4? What was changed, and how does it affect the security ("randomness") and integrity ("uniqueness")? One specific aspect I'm interested in: In v1, it seems to be about impossible to generate the same GUID on a single machine again since there was a timestamp and counter involved. In v4, this is no longer the case (I was told), so the chance to get the same GUID on a single machine ... increased?

• tetris rotation

  - by Samuel

  Hey, For university we're supposed to write a game (the language is modula2 little chance you know it). Each tetromino is defined through a central piece and 3 relative pieces, Now when it comes to rotation i just rotate the relative blocks (linear algebra). What i am asking myself is how to handle the rotations a user does when the piece has already "landed" because than the user has a little time left to move his pieve quickly into the desired position but in tetris versions all over the web you can "rotate over" other pieces, but i dont seem to get it with my rotation. Over what piece do i need to rotate? are there guidelines? Thanks

• "Tool tip" covered by ToolStripItems if they have dropdown items?

  - by Theis

  In Windows Forms - if the dropdown items of a MenuStrip has tooltips and dropdown items themselves the tooltip will have about a 50% chance of showing up below the ToolStripItems. What is the workaround? To repro you can create the MenuStrip in Visual Studio or just add the following code to a form and then try to hover your mouse over the menu items to get a tooltip: //Make a menu strip MenuStrip menu = new MenuStrip(); this.Controls.Add(menu); //Add category "File" ToolStripMenuItem fileItem = new ToolStripMenuItem("File"); menu.Items.Add(fileItem); //Add items for (int i = 0; i < 10; i++) { ToolStripMenuItem item = new ToolStripMenuItem("item"); item.ToolTipText = "item tooltip"; item.DropDownItems.Add("sub item"); fileItem.DropDownItems.Add(item); } I am using .NET 3.5

• How to use CFUUID, can CFUUID be traced back to a unique individual. security/privacy

  - by Kevin

  Hi, i an new to iphone Dev and the concept of CFUUID, so thought i should ask, before i start implementing it. so the string returned by CFUUID is it really unique or can it be traced back to a unique individual. meaning lets say, i generate a CFUUID object and convert it to string(using the methods provided) , and then this info is used in my app or stored on a server database. and how unique is it, i mean is their a chance it can be similar to one generated on some other device. is it a good idea to use this info freely or are their some security/privacy aspects that i am not thinking about here. any help is greatly appreciated thanks

• Quadratic bezier curve: Y coordinate for a given X ?

  - by stefan.at.wpf

  Hello, I have a quadratic bezier curve and I need the Y coordinate of a point on the bezier curve for a given X coordinate. I know that in pure maths this can be easily done, but I'm wondering is there's a simple / another way for this in C# / WPF? Is it possible to get the single points used by C# / WPF for drawing the bezier curve and then maybe just loop them and compare the X coordinate of each point with the given X coordinate? BTW for the mathematical way it would be good to know which step for the parameter t of the bezier curve has been choosen by C# / WPF? Any chance to find this out? Probably t is just scaled by / steps for t are 1/(distance of P0 and P2) ? Thank you very much for any hint!

• Master / Detail datagridview with relation from type string in C#

  - by Daniel

  Hello, I want to show a master / detail relationship using two datagridviews and DataRelation in C#. The relation between the master and the detail table is an ID from type string (and there is no chance to change the ID to type integer). It seems like the DataGridView is not able to update the detail view when changing the row in the master table. Does anybody know if it is possible to achieve a master / detail view using a string ID and if yes, how? Or do I have to use an external DataGrid from another company? Thanks for any help Daniel

• XML output from MySQL

  - by NumberFour

  Hi, is there any chance of getting the output from a MySQL query directly to XML? Im referring to something like MSSQL has with SQL-XML plugin, for example: SELECT * FROM table WHERE 1 FOR XML AUTO returns text (or xml data type in MSSQL to be precise) which contains an XML markup structure generated according to the columns in the table. With SQL-XML there is also an option of explicitly defining the output XML structure like this: SELECT 1 AS tag, NULL AS parent, emp_id AS [employee!1!emp_id], cust_id AS [customer!2!cust_id], region AS [customer!2!region] FROM table FOR XML EXPLICIT which generates an XML code as follows: <employee emp_id='129'> <customer cust_id='107' region='Eastern'/> </employee> Do you have any clues how to achieve this in MySQL? Thanks in advance for your answers.

• Element binding in Silverlight

  - by Matt

  Where can I find some good documentation on data/element binding? My Google searches haven't turned much up. I had a custom class with two properties named Text and Value. When I tried binding a list to a listbox it wouldn't work. By chance I modifed my datatemplate from this <TextBox Text="{Binding Text}"></TextBox> to this <TextBox Text="{Binding Path=Text}"></TextBox> and then everything worked great. I need some indepth documenation/samples to data/element binding. I don't understand why some examples have the path set whereas others do not. A full explanation of this, and all other nice to know tips would be much appreciated.

• How to make a secure game in javascript ?

  - by rnaud

  Hello, I'm working on games using javascript some html and css, and I was wondering if there was any way to secure the game so that the user can't just call game.php?result=victory to finish the game and earn some point. As of right now here are the solution I have. For a chance game, start the page with the result already in place, win or loose, then just do some animations to show it, but all the score and win/loose stuff is done server-side. For a battle game, just get the action from the javascript call, and do the damage calculation, reaction of the oponent on the server and just send back the data. but the last solution imply that I will have to send actions each time the user do anything. This might work for a turn by turn battle game, but I think it would be to slow for any other kind of game. So my question is, is there some kind of secure way I can prep my javascript to secure the infomation sent.

• Installing a source control without admin rights

  - by Simon T.

  I'm forced to use SourceSafe at my job. There is no way this is going to change. I would like to use another source control for my own need in parallel. I want to be able to keep an history of my modifications, branch easily and merge. I can install any application that doesn't requires admin rights. I cannot install Python or anything that integrates in File Explorer. I'm not much of a command line guy so a GUI is a must. I managed to install Mercurial but not TortoiseHG. There is a chance msysgit would install but the GUI isn't very good. Any suggestions?

• How to find connected hosts at network (vpn or lan)

  - by Javier Novoa C.

  Hello, I'm looking for possible solutions to the following need: I have a VPN configured (using openVPN over Linux, BTW), and I want to know at any moment which hosts are connected to it. I recognize that it probably is the same thing as trying to know which hosts are connected to a lan, so any of the solutions might do the job... The fact is that I once used a hamachi vpn on linux and with it I had the chance to know which hosts were connected to a particular network where I belonged, so I was wondering if something similar might be possible in openVPN (or even any VPN and/or any LAN). Preferably, I'm looking for opensource/free sw solutions, or maybe the hints to program it myself (in the most simple way if possible, not that I don't know how to program, but I'm trying to achieve this in a simple manner). But anyway, if there are no os/fsw solutions, any other one might do... Thanks a lot! Javier, Mexico city

• Android AccountManager API

  - by Steph

  Hi everyone, I'm struggling to understand the Android AccountManager API. As far as I got thinks working I can use the blockingGetAuthToken method and specify whether Android should provide a notification for user to allow or deny the request. Another possibility is to use getAuthToken and check if KEY_INTENT is returned. If that's the case I could start a new Activity where the user can confirm my request. My problem is that I would like to call one of these two methods from within a Service. Is there any chance to get a callback once the user has made a decision? Thanks for your help

• Maven: How to create assembly with snapshot artifacts without timestamps file name?

  - by marabol

  I've a repository containing snapshot artifacts with timestamps. I want to create an assembly, that contains the dependencies. This works fine. But the artifact names contains the timestamp. So i wonder how to remove the timestamp from filename for the assembly only. I've used this dependencySet: <outputFileNameMapping>${artifact.artifactId}-${artifact.version}.${artifact.extension}</outputFileNameMapping> But version seams to contain already the timestamp. So is there any chance to get a 1.1.1-SNAPSHOT instead of 1.1.1-20100323.071348-182?

• Is it possible to "merge" the values of multiple records into a single field without using a stored

  - by j0rd4n

  A co-worker posed this question to me, and I told them, "No, you'll need to write a sproc for that". But I thought I'd give them a chance and put this out to the community. Essentially, they have a table with keys mapping to multiple values. For a report, they want to aggregate on the key and "mash" all of the values into a single field. Here's a visual: --- ------- Key Value --- ------- 1 A 1 B 1 C 2 X 2 Y The result would be as follows: --- ------- Key Value --- ------- 1 A,B,C 2 X,Y They need this in SQLServer 2005. Again, I think they need to write a stored procedure, but if anyone knows a magic out-of-the-box function that does this, I'd be impressed.

• Calculating spam probability in python

  - by Hobhouse

  I am building a website in python/django and want to predict wether a user submission is valid or wether it is spam. Users have an accept rate on their submissions, like this website has. Users can moderate other users' submissions; and these moderations are later metamoderated by an admin. Given this: user A with an submission accept rate of 60% submits something. user B moderates A's post as a valid submission. However, his moderations are often wrong, and his moderations' accept rate is a mere 30%. user C moderates A's post as spam. User C is usually right. His moderations' accept rate is 80%. How can I predict the chance of A's post being spam?

• Using Custom HttpHandler to redirect users in Sharepoint

  - by BeraCim

  Hi all: I need to redirect a user to a different page if they visit a certain set of pages in a web. There is one condition: I'm not allowed to touch the IIS. I have googled around and found a thing called the custom HttpHandler for WSS 3.0. It sounded like something that I can use to capture the URL the user enters (the most malicious way to get to a page that should really be redirected) and redirect them to another page/web. But having not have the chance to use it yet, I was wondering am I on the right track by using a Custom HttpHandler to redirect a user to a different page in Sharepoint using C#? Many thanks.

• How do I properly handle a faulted WCF connection?

  - by mafutrct

  In my client program, there is a WCF connection that is opened at startup and supposedly stays connected til shutdown. However, there is a chance that the server closes due to unforeseeable circumstances (imagine someone pulling the cable). Since the client uses a lot of contract methods in a lot of places, I don't want to add a try/catch on every method call. I've got 2 ideas for handling this issue: Create a method that takes a delegate and executes the delegate inside a try/catch and returns an Exception in case of a known exception, or null else. The caller has to deal with nun-null results. Listen to the Faulted event of the underlying CommunicationObject. But I don't see how I could handle the event except for displaying some error message and shutting down. Are there some best practices for faulted WCF connection that exist for app lifetime?

• Rails uniqueness constraint and matching db unique index for null column

  - by Dave

  I have the following in my migration file def self.up create_table :payment_agreements do |t| t.boolean :automatic, :default => true, :null => false t.string :payment_trigger_on_order t.references :supplier t.references :seller t.references :product t.timestamps end end I want to ensure that if a product_id is specified it is unique but I also want to allow null so I have the following in my model: validates :product_id, :uniqueness => true, :allow_nil => true Works great but I should then add an index to the migration file add_index :payment_agreements, :product_id, :unique => true Obviously this will throw an exception when two null values are inserted for product_id. I could just simply omit the index in the migration but then there's the chance that I'll get two PaymentAgreements with the same product_id as shown here: Concurrency and integrity My question is what is the best/most common way to deal with this problem

• How to validate HTTP request headers before receiving request body using WCF

  - by anelson

  I'm implementing a REST service using WCF which will be used to upload very large files. The HTTP headers in this request will communicate information which will be validated prior to allowing the upload to proceed (things like permissions, available disk space, etc). It's possible this validation will fail resulting in an error response. I'd like to do this validation prior to the client sending the body of the request, so it has a chance to detect failure before uploading potentially gigabytes of data. RESTful web services use the HTTP 1.1 Expect: 100-continue in the request to implement this. For example Amazon S3's REST API can validate your key and ACLs in response to an object PUT operation, returning 100 Continue if all is well, indicating you may proceed to send your data. I've rummaged around the WCF documentation and I just can't see a way to accomplish this without doing some pretty low-level hooking into the HTTP request processing pipeline. How would you suggest I solve this problem?

• Does GIT have evil twin issues?

  - by Senthil A Kumar

  In ClearCase evil twin occurs when two files are found with the same name in two different versions of the directory, and If the element OIDs are different but the names are the same. In GIT the SHA1 id is always unique and file with same name always have different SHA1 id’s. We don’t have a concept of Evil twins, but there are likely cases where there is chance for 2 or more developers creating a file with different contents with same filename in the same directory. During merge, when both files are completely different, there are chances of the developers to keep his changes alone and leave other changes resulting in code loss. Can anyone let me know if there will be issues in GIT similar to ClearCase or sine each SHA1 id is unique there won't be any Evil twin issues in GIT.

• Can only "agents" build and submit Applications to Apple?

  - by Martin

  I'm afraid I know the answer to this but I'll ask on the longshot chance that I'm wrong: I've been doing some freelance work creating an iPhone application for a company. They've created their own developer account and added me as an team member with "admin" rights. That seems to be the highest assignable rights (with the only higher level being "agent" and belonging only to whoever signed up for the account). Yet, I don't have an option under the provisioning portal to create a distribution certificate or profile. Is there any way to create these myself without having to ask my client for their primary login? They're not particulary tech savy so it would be difficult to walk them through the process to create the necessary certificates (and would require me giving them a certificate request from my computer, etc. etc.). But it seems like there should be some way to create a distribution build without "agent" rights, right? Could Apple seriously expect only one person from a company to do all the building and uploading of apps to the store?
