• Comma or semicolon-delimited AutoComplete TextBox

  - by Ecyrb

  I would like to have a TextBox that supports AutoComplete and lets users type multiple words separated by a comma or semicolon, offering suggestions for each word. I have a standard TextBox with textBox.AutoCompleteCustomSource.AddRange(new[] { "apple", "banana", "carrot" }); textBox.AutoCompleteMode = AutoCompleteMode.SuggestAppend; textBox.AutoCompleteSource = AutoCompleteSource.CustomSource; Unfortunately it will only suggest for the first word. Anything typed after that and it stops suggesting. I want to be able to perform the following scenario: Type "ap" Have it suggest "apple" Press the comma Have it fill in "apple," with the cursor after the comma Type "ba" Have it suggest "banana" Press the comma Have it append "banana," resulting in "apple,banana," I've tried Googling for a solution, but haven't had much luck. This seems to be a popular feature for web apps, but apparently not for winforms. Any suggestions?

• Manually inserting varbinary data into SQL Server

  - by Jeremy Jarrell

  Hi, We have a SQL Server table for user settings. Originally the settings were domain objects which had been serialized as XML into the table but we recently begun serializing them as binary. However, as part of our deployment process we statically pre-populate the table with predefined settings for our users. Originally, this was as simple as copying the XML from a customized database and pasting it into an INSERT statement that was ran after the database was built. However, since we've moved to storing the settings as binary data we can't get this to work. How can we extract binary data from a varbinary column in SQL Server and paste it into a static INSERT script? We only want to use SQL for this, we don't want to use any utilities. Thanks in advance, Jeremy

• Asp.net mvc application deployment / security issues

  - by WestDiscGolf

  I'll start with appologies; I wasn't sure if this was best posted here of Server Fault so if its in the wrong place then please move :-) Basic information I have written the first module of a new application at work. This is written using Visual Studio 2010, targetting .net 3.5 (at the moment) and asp.net mvc 2. This has been working fine during development running on the built in Development server from VS but however does not work once deployed to IIS 7/7.5. To deploy the application, I have built it in release mode and created a deployment package by right clicking on the project in the solution explorer (this will be done with an automated build in tfs once upgrade from the beta). This has then been imported into IIS on the server. The application is using windows/domain authentication. Issue #1 I can fire up internet explorer and browse to the application from a client computer as well as on a remote desktop connection. I can execute the code which reads/stores data in Session fine from the IE instance on the remote desktop but if I browse to it from the client pc it seems to lose the session state. I click on the form submit and the page refreshes and doesn't execute the required code. I've tried setting with; InProc, SQLServer and StateServer. but with no luck :-( Issue #2 As part of the application it views PDF and Tiff documents on the fly which are on a network share on the office network and creates thumbnails if the document hasn't been viewed before. This works if running on the machine the application is deployed to; however when browsing from a client pc I get an error saying: Access to the path '\\fileserver\folder\file.tif' is denied Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access to the path '\\fileserver\folder\file.TIF' is denied. ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. As this is on a different server the user is not accessible. To get round this I have tried: 1 - setting the application pool to run as domain administrator (I know this is a security risk, but I'm just trying to get it to work at the moment!) 2 - to set the log on account for World Wide Web Publishing service to be the domain admin . When trying to restart the service I get ... Windows could not start the World Wide Web Publishing Service service on the Local Computer. Error 1079: The account specified for this service is different from the account specified fro the other services running in the same process. Any pointers/help would be much appriciated as I'm pulling my hair out (of what little I have left). Update I've been using this funky little tool I found - DelegConfig v2 beta (Delegation / Kerberos Configuration Tool). This has been really usefull. So I've got the accessing of the file share working (there is a test page which will read the files) so now I've just got the issue of passing through the users credentials through to the SQL Server (wans't my choice to do it this way!!) to execute the queries etc. but I can't get it to log on as the user. It tries to access it as "NT Authority\Network Service" which doesn't have a sql login (as should be the logged on user). My connection string is: <add name="User" connectionString="Data Source=.;Integrated Security=True" providerName="System.Data.SqlClient" /> No initial catalog is specified as the system is over multiple dbs (also wasn't my choice!!). I really appriciate all the help so far! :-) Any further hints?!

• How to sync with eclipse target management?

  - by SpliFF

  I've been using the Jcraft SFTP plugin for Team Synchronisation up till now but I ran across a rumour it's being deprecated by "Target Management". Still, despite my best efforts I haven't found any information on HOW you are supposed to setup a sync with RSE/Target Management. Can anybody provide a step-by-step guide or at least clarification on whether this is actually possible right now or just a planned feature. I do my testing locally then sync to the remote - which may have changes made by other users. I want to be able to see differences and deal with conflicts etc just like with the current Team Synchronization framework.

• Changing resource file in new version of an app

  - by Michael Frost

  Hi, I'm working on an update for an already existing iphone app. The existing version contains a .sql database file which is used in the app. I would like to use a new version of this file in the update of the app. On the first startup of the existing app the .sql file is placed in the caches directory of the users iphone. From what I can understand from Apple's documentation the files in the caches directory might get copied from the old app to the new versions caches directory when the user updates the app. Does this mean that for being sure my new file is used in the updated version I should use a different name of the file? And what happens with the old file? Do I have to manually delete it from inside the app? Which means I have to check if it's there at every startup of the app? Thanks Michael

• Using implicit conversion as a substitute for multiple inheritance in .NET

  - by Daniel Plaisted

  I have a situation where I would like to have objects of a certain type be able to be used as two different types. If one of the "base" types was an interface this wouldn't be an issue, but in my case it is preferable that they both be concrete types. I am considering adding copies of the methods and properties of one of the base types to the derived type, and adding an implicit conversion from the derived type to that base type. Then users will be able treat the derived type as the base type by using the duplicated methods directly, by assigning it to a variable of the base type, or by passing it to a method that takes the base type. It seems like this solution will fit my needs well, but am I missing anything? Is there a situation where this won't work, or where it is likely to add confusion instead of simplicity when using the API?

• How to access the theming Fonts and Colors on GTK/Gnome

  Lets say i want to write a special text editor widget. How can i get the default themed colors for texts, selected text and background and which are the users default fonts? I see that GNOME does define 5 special system fonts and default sizes for this purpose in the GNOME Appearance Configuration dialog, but i haven't found a single word in the GTK documentation how to access them (and the GTK mailing list is a joke:-( ). Windows and Cocoa both give me dozens of system values. I found the GtkStyle class but this doesn't seem to be what i need.

• How best to pre-install OR pre-load OR cache Java Script library to optimize performance.

  - by Kabeer

  Hello. I am working for an intranet application. Therefore I have some control on the client machines. The Java Script library I am using is somewhat big in size. I would like to pre-install OR pre-load OR cache the Java Script library on each machine (each browser as well) so that it does not travel for each request. I know that browsers do cache a Java Script library for subsequent requests but I would like the library to be cached once so all subsequent requests, sessions and users. What is the best mechanism to achieve this?

• How to "smart resize" a displayed image to original aspect ratio

  - by Paul Sasik

  I have an application in which end-users can size and position images in a designer. Since the spec calls for the image to be "stretched" to the containing control, the end user can end up with an awkwardly stretched image. To help the user with image sizing I am thinking of implementing a smart resizer function which would allow the the user to easily fix the aspect ratio of the picture so that it no longer appears stretched. The quick way to solve this is to actually provide two options: 1) scale from width 2) scale from height. The user chooses the method and the algorithm adjusts the size of the picture by using the original aspect ratio. For example: A picture is displayed as 200x200 on the designer but the original image is 1024x768 pixels. The user chooses "Smart Size from width" and the new size becomes ~200x150 since the original aspect ratio is ~1.333 That's OK, but how could I make the algorithm smarter and not bother the user by asking which dimension the recalculation should be based on?

• Twitter API and rate limiting - I am confused

  - by jeffreyveon

  I am new to the Twitter API, and I looked at their whitelisting policies and I am a little confused... I'm basically writing a twitter aggregrator that crawls the public tweets of a set of users (not more than 200) hourly. I wanted to apply for whitelisting, and they seem to offer account based and IP based whitelisting. Since I am using a shared hosting, my outbound IP address might vary (and twitter does'nt allow IP ranges for whitelisting). So I am considering using account based whitelisting. However, while using OAuth, is it possible for me to use account based whitelisting for a background process that crawls the API hourly?

• restrict access to page to only be allowed from a certain page

  - by controlfreak123

  This question is similar to the one i asked here. But its related because I want to achieve the same effect. I want the users to be restricted to only accessing other pages on the site through the main page. The first page contains a frame for navigation and then a frame for content of the page they navigate to. I want it to be setup so that the only way they can access the content pages is by using this main page. So if the main page is http://intranet/index.html then they cannot get to http://intranet/other_page.html without using the link provided in index.html. Is this possible and if so what would the best technique be? I'm using apache to serve the site and I have php and javascript available.

• Facebook Connect: proxied_email not always returned by users_getInfo

  - by PeterP

  Today I realized that FB Connect does not return the proxied_email field in about 4 out of 5 times. (I can reproduce this with a single users repeatedly, so this obviously does not have anything to do with privacy options or permissions) It definitely worked fine last week ago. I could not find any official info that this field is going to be removed or anything, so... Does anybody else have this problem? Is there anything I am doing wrong that could be causing this behavior? Or is Facebook just having a bad day?

• Experiences with "language converters"?

  - by Friedrich

  I have read a few articles mentioning converters from one language to another. I'm a bit more than skeptical about the use of such kind of tools. Does anyone know or have experiences let's say about Visual Basic to Java or vs converters? Just one example to pick http://www.tvobjects.com/products/products.html, claims to be the "world leader" or so in that aspect, However if read this: http://dev.mysql.com/tech-resources/articles/active-grid.html There the author states: "The consensus of MySQL users is that automated conversion tools for MS Access do not work. For example, tools that translate existing Access applications to Java often result in 80% complete solutions where finishing the last 20% of the work takes longer than starting from scratch." Well we know we need 80% of the time to implement the first 80% functionality and another 80% of the time for the other 20 %.... So has anyone tried such tools and found them to be worthwhile?

• Broadcast-style Bluetooth using Sockets on the iPhone?

  - by Kyle

  Is there any way to open a broadcast bluetooth socket, take a listen and send replies? I want a proper peer to peer system where I broadcast and listen for broadcasts in an area. That way, variable clients can mingle. Is this possible? My theory is this: If GameKit can sit around wasting 25 seconds of the users time whilst having access to a broadcast socket, can't I? Or, must I be in kernel mode for such access? I'm not really sure where the proper bluetooth headers are as well. Thanks for reading!

• Using Facebook Connect with jQTouch?

  - by Volmar

  Hi, i'm starting a new jQTouch-project now and i'm thinking of using facebook connect to make it easier for users to register with my site. do anyone have any experience with this? I'm using the Facebook PHP SDK (from github), and i first tried to use it with the built in example, it worked good. i later tried it with jQTouch (the latest build from the SVN). when i create the log in/log out link inside a ul.roundedli element it does not work because jQTouch have some special function that handles links clicked inside a li-element. how can i go around this function and make it work with the connect-link, i'm using the display=touch version of the autentication dialog. when i add the link outside of the ul.roundedli-element it works in desktop safari but not in mobile safari. any ideas?

• Is there a Drupal module for Forms with powerful CRUD style behaviour?

  - by Petras

  We are building a website that contains a large number of database tables that need to be edited by the CMS administrator. Some of the tables are fed by form submissions from users on the front end of the website. Some of the tables are purely in the CMS and are used to create custom modules on the front end of the website. Although there is a forms module in Drupal, I think our requirements cannot be met by it. Does anyone know of a system that allows forms to be saved to a CRUD style database with the following features? Export of all database fields. View a summary of the records in a filterable table. With paging You can have one to many relationships in records eg To code this manually for 10 forms is A LOT of work. Particularly the one to many relationships. If there is a powerful module available it would save us writing one.
