• make desktop sms application using blackberry

  - by Amit Kumar Jha

  hey all, I have to make a SMS sending application in .NET, which uses the attached Blackberry handset(blackberry tour 9630 to be precise) to send SMS. I have never worked on smartphone application development, so want help in doing this. I searched SO for an answer and found one question, but its in java and i think that code would run on blackberry itself and not on desktop, correct me if i am wrong. So if someone could point me in the right direction I would be very grateful. Thanks in advance to all those who reply.

• How to create and download an XML without storing it on the server

  - by CiccioMiami

  NET Web Forms** application. I would like to create a download link to make available to the user the possibility to download an XML file. However the file does not have to be stored on the server. In my aspx file I have the download link (placed inside a GridView): <asp:HyperLinField Text="Download" DataNavigateUrlFormatString="download.aspx?ProductId={0}" DataNavigateUrlFields="ProductId"> In the download.aspx.vb page: Dim productId As String = Request.QueryString("productId") Dim xmlDoc As String = _ProductServices.GetXmlDocPerId(productId) Dim xdoc As XmlDocument = New XmlDocument() xdoc.LoadXml(xmlLicense) Now I would like to create a file, place the XML content inside and deliver it to the user without saving it to the server. Shall I use a MemoryStream combined with a StreamReader?

• What is the equivalent to IScriptControl for Web.UI.Page?

  - by Jeff Dege

  We've been using IScriptControl to tie javascript objects to our UserControls and ServerControls, and it's worked fine. The problem is that ASP.NET seems to provide no method to tie a javascript object to a Page. Up to now, we've been putting plain functions in the global namespace, but I am developing a serious allergy to that practice. It'd be easy enough to wrap our functions into a javascript class, and to include the javascript file on the page, but how to instantiate the object, how to reference it from callback events, and how to pass data to it from the code-behind, I haven't figured out. Or rather, the methods we've been using up to now (hidden fields, emitted javascript strings, etc.), really bug me. Anyone have better ideas?

• How to change proxy settings while using Watin?

  - by john

  Hi, I am using Watin mostly to automate thing I do by hand. Sometimes, I need to change proxy. To do this, I have to set up IE to use a local proxy all the time (listens locally and forwards to a remote porxy), and then by hand change the settings of that program each time I need to use another proxy. This is not an elegant solution! It may work, but it is not nice. So, my question is, how do I change programmatically IE settings while using Watin? I code in VB.NET. Thank you

• Difference of two 'uint'

  - by vanslly

  When you attempt to declare an unsigned variable in C#.NET with a value outside its value range it is flagged as a compiler error, but if you produce a negative value at runtime and assign it to that variable at runtime the value wraps. uint z = -1; // Will not compile uint a = 5; uint b = 6; uint c = a - b; // Will result in uint.MaxValue Is there a good reason why unsigned variables wrap in such a situation instead of throwing an exception? Thanks.

• How to get a count of ManagementObjects (WMI results) without enumerating through the collection in

  - by Mark

  When querying for large ammount of data through WMI (say the windows events log Win32_NTLogEvent) it is very useful to know what kind of numbers you are getting yourself into before downloading all the content. Is there a way two do this? From what i know there is no "Select Count(*) FROM Win32_NTLogEvent" in WQL. From what i know the Count property of the ManagementObjectCollection actually enumerates through all the results whether you have the Rewindable property set to true or false. If it cannot be done in .NET, can it be done by directly using the underlying IWbem objects Thanks

• jQuery Validate Plugin overwrite my select onChange postback

  - by C.Hoffmann

  Hi, I'm creating this form (.net) where i have a select with a postback, that will trigger a action depending on which option i select. I'm trying to use the jQuery Validate Plugin (plugin website) to validate my form. My problem is, when i validate the form, and my select is marked as invalid, the validation plugin overwrite it's onChange method to make it unmark when i change the value, the thing is that it's deleting my __dopostback from the onchange, making the form 'useless'. Is there a way to the plugin validate my selects without deleting my postback action from the onchange?

• Silverlight MediaElement issue

  - by George2

  Hello everyone, I am using Silverlight 3.0 + .Net 3.5 + VSTS 2008 + C# to develop a simple video application using MediaElement of Silverlight. I have two videos and I want to play them at the same time (similar to picture in picture effect) -- i.e. a part of the two videos are overlapped when they are playing (the same concept of Z-Order in UI design). I want to play one MediaElement on top of the other MediaElement, and I am wondering how to assign the overlap order (similar to set Z-Order UI element, but I did not find MediaElement has Z-Order property)? thanks in advance, George

• Mixing Transaction Script pattern with DDD/CQRS

  - by Herman

  Hi all, Here is the situation, in order to support our legacy system, we need to insert to a table whenever a user logs in. This is basically an CRUD operation, so it doesn't really make sense to create repository/entity/command/event for this since this doesn't tie to any business rules at all. The only benefit to create a CQRS command is that this database write can happen asynchronously under that model. Which is a better route to take? Use CQRS, and then call a stored proc. when handling that command? Just call database directly in the controller (I am using asp.net mvc)

• CKEditor 3.2 is un-editable in jQuery simpleModal

  - by Gal V

  Hello all, I noticed that this isn't the first time that this issue comes up, but I still couldn't find the right and working solution for me. Here is the thing- In my ASP.NET aspx page I created a div element, with a <cc1:CKEditor> control tag within it. This div is hidden, and is attached to a jQuery SimpleModal plugin. The problem is- that when I trigger the modal-opening and the modal shows up with the editor within it, the editor is UNEDITABLE, locked. How can I fix it, and enable the editing in the CKEditor's textarea? Thanks in advance!

• jQuery Autocomplete losing text on AutoPostBack

  - by Moose

  I have a jQuery Autocomplete field on an ASP.Net Webform and everything has been working great until now. I also have a DropDownList that I have a need to fire onSelectedIndexChanged with AutoPostBack. When I changed my code to do the AutoPostBack, the text field that has the jQuery AutoComplete on it comes back blank. However, if I look at the source of the page, the text is in the text field. If I now post the form, the page will send back a blank field. My Google-Fu is weak on this one, as I could not come up with any workaround for it. Has anyone had any issues like this with the Autocomplete field getting blanked out on an AutoPostBack, and how did you get around it? I can post code if it's really necessary, but I'd need to sanitize a lot of it before I could due to company policy.

• How to programatically record the start and end of an MVC FileResult for logging of incomplete downl

  - by Richard

  Hi, I have been investigating how My ASP.NET MVC application can log unsuccessful / incomplete downloads. I have a controller handling the file requests which currently returns a FileResult. What I need to record is the IPAddress, filename and when the download started, then the same data and when it completed. I have looked at intercepting the request start and end with an HttpModule and also IIS7 failed request tracing but am not sure which route would be best and have this feeling that maybe I am missing an obvious answer to the problem. Does anyone have any suggestions or know of any alternatives as this seems like something many people would want to know from their web server? Thanks for your help

• Sessionstate not being saved between pages

  - by Grant

  Hi, i am having problems with an asp.net c# site whereby i am setting a session state object to true and then redirecting to another page that needs to check the value of the session state object and it is null. Sometimes it is set correctly and other times is is simply null. When i debug on my local machine it works perfectly every time. Only when i upload to my web server does this temperamental behaviour happen. As it is based around the security of the site it is obviously important that the session data be valid and accurate every time. Is session state data unreliable? AFAIK its set to inproc, cookieless, 30 min timeout, vanilla installation of IIS. Does anyone have any suggestions? Perhaps i need to thread.sleep inbetween the storing of the session data and the reading? NB: the time between the write and the read is about 70ms.. ample time for the data to be written to RAM.....

• how to store dynamically generated pages in html?

  - by Dharmik Bhandari

  I'm working on ASP.net MVC3 Web application that is facing scalability issue. For improving performance I want to store dynamically generated pages in html and serve them from generated html directly rather then querying database for each page request. I'm sure this will dramatically increase performance. Can any one share any hint / example / tutorial on how to do it? And what are challenges? I would also like to know how others are handling performance issue for large e-commerce sites with at-least thousand categories and 200k products with at least 200-500 concurrent visitors? What are the best approaches? Thanks in advance.

• How to create a custom ADO Multi Demensional Catalog with no database

  - by Alan Clark

  Does anyone know of an example of how to dynamically define and build ADO MD (ActiveX Data Objects Multidimensional) catalogs and cube definitions with a set of data other than a database? Background: we have a huge amount of data in our application that we export to a database and then query using the usual SQL joins, groups, sums etc to produce reports. The data in the application is originally in objects and arrays. The problem is the amount of data is so large the export can take 2 hours. So I am trying to figure out a good way of querying the objects in memory, either by a custom OLAP algorithm or library, or ADO MD. But I haven't been able to find an example of using ADO MD without a database behind it. We are using Delphi 2010 so would use ADO ActiveX but I imagine the ADO.NET MD is similar. I realize that if the application data was already stored in a database the problem would solve itself. Also if Delphi had LINQ capability I could query the objects and arrays that way.

• Finding the best folder for all users on a Windows machine

  - by reallyjoel

  We are making a game which will add a level editor feature soon. We want the user to be able to put levels he's downloaded in a folder and then play it in the game, without any hassle. So, we're looking for a folder that anybody can find, open, write, read, and is multiuser. On Windows Vista / 7, the folder /Users/Public/ look like a great candidate. However, It's not listed in the .net enum System.Environment.SpecialFolder. I have went through them all, and checked what they yield on different Windows versions, and none live up to my requirements. I did find Environment.SpecialFolder.CommonApplicationData, that kinda works, but that folder is hidden (C:\ProgramData) and I assume most users don't display hidden folders. As it stands now, it looks like we'll have to settle for the personal documents folder, but we'd really like a multi user folder? Anyone have any tips? (Hard coding c:\Users\Public\ is out of the question, it will only work on english systems)

I am doing in in C# .NET framework 3.5 When I attempt to compile, the compilation takes place, but the executable throws this error message.

An attempt was made to load a program with an incorrect format. Is there some way to get around this? What could be causing this to happen?

• Assembly.CodeBase: when is it no file-URI?

  - by Marc Wittke

  Assembly.Location gives a plain path to the assembly. Unfortunately this is empty when running in a shadowed environment, such as unit test or ASP.NET. Hovever, the Codebase property is available and provides a URI that can be used instead. In which cases it returns no URI starting with file:///? Or in other words: what are the cases in which this won't work or will return unusable results? Assembly assembly = GetType().Assembly; Uri codeBaseUri = new Uri(assembly.CodeBase); string path = codeBaseUri.LocalPath;

• Casting DataTypes with DirectCast, CType, TryCast

  - by Alex Essilfie

  Ever since I moved from VB6 to VB.NET somewhere in 2005, I've been using CType to do casting from one data type to another. I do this because it is simply faster, used to exist in VB6 and I do not know why I have to be using DirectCast if there is apparently no difference between them. I use TryCast once in a while because I understand that sometimes casting can fail. I however cannot get the difference between CType and DirectCast. Can anyone tell me the difference in plain simple English what the difference the two (CType and DirectCast)? Adding examples of where to use what as well would be helpful. Thanks.

• What does Visual Studio 2008 do when I add an assembly reference?

  - by tk-421

  When I add a reference to an assembly (living in the GAC) to web.config in an ASP.NET project, what does Visual Studio do? [This is related to an earlier question pertaining to BusinessObjects: http://stackoverflow.com/questions/2379615/ ] When I add "CrystalDecisions.Enterprise" and "CrystalDecisions.Enterprise.Framework" to the assemblies element in web.config, VS thinks long and hard about it, locking me out for a couple of minutes while it scrutinizes the newcomers. What is it doing during this time? I Googled this but came up empty. I can make some educated guesses (IntelliSense integration, perhaps?) but would ideally like to find some documentation describing exactly what's going on. Ultimately I'm hoping to learn why these BO references are making VS take several minutes to open my projects (I struck out on the SAP forums).

• Performance monitor shows 4294967293 sessions active

  - by TGnat

  I have an ASP.Net 3.5 website running in IIS 6 on Windows Server 2003 R2. It is a relatively small internal application that probably serves less than ten users at any given time. The server has 4 Gig of memory and shows that 3+ Gig is available while the site is active. Just minutes after restarting the web application Performance monitor shows that there is a whopping 4,294,967,293 sessions active! I am fairly certain that this number is incorrect; at the time this reading there were only 100 requests to the website. Has anyone else experienced this kind odd behavior from perf mon? Any ideas on how to get an accurate reading? UPDATE: After running for about an hour the number of active sessions has dropped by 4. So it does seem to be responding to sessions timing out.
