C# - White-labelling .NET Webapp?
Nov 26, 2010
I have an ASP.NET webapp that business customers in India wish to purchase and run within their premises (it's for industrial use). What's my best approach to do this, but not lose control of my IP? Some concerns I had:
Does ASP.NET4 code still need to get obfuscated to protect against reverse engineering, and how would this be done?Do I need to create a separate build specific to each customer that is restricted in some manner (eg. tied to physical box attributes such as CPU)?Is it possible for me to be the sole admin on the box, but give remote access to the folders that contain my CSS and HTML. That way I can maintain control over the code, but give the limited access the custom needs to customize the webapp to their site's look and feel.

i have a gridview bound to sql datasource with template fields binding the columns. I have set the Header Style to a css class. I have 3 columns not bound to data as Add, Edit and Delete. When I set the text color to white for the header only the non bound columns go white. The bound columns are BLUE like hyperlink. Any one know a way round this. (If I set the style in the gridview the all columns are white. Want to set in external css file).

I've been working on an asp web application, which involves the user registering details of a person, including an image of the person. The file name of the details/image are stored in a SQL database with the image filename storied in an NVARCHAR column, rather than storing the actual image in the DB.I created a directory C:Images to which the image files would be stored by the application. The application works correctly in as far as it moves the images to this location, but when I open the page which would display the details/image the image never renders.
I got round this during development by having the image stored in a folder which was part of the project, but after release of the project to the server, the application refuses to allow the image to be saved in any directories within C:Inetpubwwwroot .So I need find out why the images won't render when they are stored in folders not within the project.I've checked the source of the HTML page which also points to the correct location and file name:
img id="ctl00_MainContent_CandidateImage" src="C:Imagesapplicant11.jpg" alt="Candidate Image" style="border-width:1px;border-style:solid;height:208px;width:208px;"
The code behind page renders the image in the code below:
// CandidatePhoto filename retrieved from DB.
CandidateImage.ImageUrl = "C:\Images\" + CandidatePhoto;

HttpResponse.End() seems to throw an exception according to msdn.Right now i have the choice of returning a value to say end thread(it only goes 2 functions deep) or i can call end().
I know that throwing exceptions is significantly slower (read the comment for a C#/.NET test) so if i want a fast webapp should i consider not calling it when it is trivially easy to not call it?
-edit- I do have a function call in certain functions and in the constructor in classes to ensure the user is logged in.So i call HttpResponse.End() in enough places although hopefully in regular site usage it doesn't occur too often.

Is there a way to ship a small webapp in MVC2 with IIS Express, so there will no need for installing it on IIS, what's the version, ohh I don't have cause I want to run this on Windows Vista Home, etc etc ...
Kind'a having a small exe and run the WebApp on the IIS Express, for those who prefer the web environment rather than a windows environment to work, and off course, been a webapp, it should be able to be access it from any computer on the ethernet.

I am doing some prelim work on an insurance webapp that will take the place of the old legacy system currently in use. Looking mainly at such things as design techniques, looks, flow, etc. Others are working on the updated db. The eventual plan is to assemble this development in sections. Sections such as policy management, claims management, risk management, and so on.
What I am posting about is to see if anyone has worked on such a development and if so would it be better to do a website or a webapp? Does anyone know of any websites that would have screenshots of the different screen sections for viewing? These will at least get the group looking and thinking of what is needed for when the real design time comes. Any open source that is available to view? Like I mentioned this is just some early prelim work being done. I've been doing some googling but not finding a whole lot.

I've just been looking around a little at the Devexpress PivotGrid/PivotTable and wow, I'm impressed (see here for an example, skip towards end to see some of the functionality).
I'm working on a java webapp in which the tabular data presented is the key part of the application, and if I could implement something such as the Devexpress control that would be amazing. Is there anything out there?? The java webapp uses the myfaces framework.

I need to insert records in my webapp into a simple sql-db-table. The thing is, that the user chooses the position of every new record to insert. If I take an integer index, and the user want to insert an object between the 3rd and the 4th object, it is not possible, because 3.5 is no integer-value. An index of real could be the solution. Probably a litte complicated, as soon as a new object needs to be inserted between 3.45 and 3.89 (example).
If you know an easier approach for inserting records at any position by having the ability to sort by the initially choosen order (index?)

TL;DR - Any webapp devs out there able to squeeze performance out of using gmail as SMTP server without a 3-10 minute delay to delivery?I'm looking for some feedback from developers who are using gmail as a secure SMTP server for use with Webapps.Within the past 2 weeks, my company has switched to gmail to host email for our domains.I have a few webapps that send from our ISP server, but I'd like to refactor the code to use gmail with our domain name. I know the ISP can rig things up, but I don't want relay issues.I have gmail sending for the Webapps and it's more or less working. On ASP/IIS, I'm using SSL and on PHP Linux, I'm using TLS.It seems that TLS (port 587) works better than plain old SSL (port 465), but the overall performance difference seems minimal.What concerns me is that there is often a significant delay (10-20 minutes at times) to get email to a recipient no matter which method I use to send via gmail.While I understand this can happen in any environment, I am used to fast delivery. Use case is salespeople talking to customers and needing to get email to them very quickly using the Webapp. Before the gmail switch, usually less than a minute to deliver. Now, it is 3-4 minutes minimum.Am I crazy to try to use gmail for this purpose? There seem to be a lot of devs using it, so just wanting to know how it works out for them/you.

I work for a local library that just had a consulting company do a migration of their IIS installation from one server to another.It wasn't until a few days ago that my boss noticed that login.aspx seemed to have broken. I have little knowledge of ASP.NET but I just have a feeling this is something really simple. Here is the error when trying to login to the webapp:
Error authenticating. Error authenticating user. The specified domain either does not exist or could not be contacted.Active Directory was on a completely different machine and was not migrated to different hardware .The app connects to a sqlexpress server and that is running and the database is there ... Under ASP.NET Configuration Settings the sqlServerWebConnection points to the machine running the sql server. What am I missing?
EDIT: Under login.aspx.cs I have
string adPath = "LDAP://DC=COMPANY,DC=org"; //Path to your LDAP directory server ecause the webapp used to run on IIS on the DC, is that the line that somehow needs modified?

For the solution, I cannot use any event handling methods, because my webapp is fully ajax based and no complete postback is possible. So here's the problem.I have a `List<WebPage>` that contains a list of Links `(List<Link>)` and I need for all the links to bind repetitive information such as page title, id, url. Here is my current repeater.

I have created a webapp using all of the recommended link and meta tags for safari, eg.
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<link rel="apple-touch-startup-image" href="/startup.png" />
<link rel="apple-touch-icon" href="/apple-touch-icon.png" />
<link rel="apple-touch-icon" sizes="72x72" href="/apple-touch-icon-ipad.png" />
<link rel="apple-touch-icon" sizes="114x114" href="/apple-touch-icon-iphone4.png" />
However, my issue is if the startup.png or any of the apple-touch-icon image files are updated on the webserver, it doesn't seem like a user's iphone or ipod will retreive the updated file once it has been saved to their home screen (I'm guessing it's cached somehow or something). It works to remove the webapp from the home screen and re-add it. But is there a way to let the application know it needs to refresh these images without requiring the user to delete and re-add it?

I am trying to implement charting into one of my sites, and I am having a hard time styling the border to make it transparent.
I've attached a image so you can see what it is I am talking about. I have yet to figure out what needs to be set to get rid of the white under the drop shadow ...
If anyone has any ideas I would love to hear how to get rid of this ...

In my website, users have the ability to upload images to my website. When the image is uploaded it will automatically have a smaller thumbnail created by my website. The thumbnails are not displaying correctly in my repeater though (and by correctly I mean Im not sure how to display them).
Each image sits inside a square div element which is 145 x 145 pixels. Some of the images are 145 wide with a relative height and some are 145 high with a relative width. When my page is displayed the wider images sit at the bottom of my 145 x 145 div,whereas the higher image sit at the bottom and to the left. I would prefer them to all be centered.
I cant find a way to do this is in CSS becuase the images are retrieved dynamically so I cant assign a height beforehand. Is there a way to add white space to my image during the thumbnail creation process so that all images are 145 x 145 but still maintain the aspect ratio? Or can someone think of a good way to do this with CSS and HTML, OR even with javascript (keeping in mind that my images come inside a repeater bound to data in the db.
If you want to see any of my code or the thumbnail creating class just ask.

I'm not sure why this is, basically when I insert a row using the following function:
[code]....
The field 'Password' ends up having white spaces in it (as in "Password "). So whatever the password is it's trailed by white spaces.
The strange thing is this doesn't happen to the field 'UserName', both are of type char(50).
