Article commenting by line number


I'm wondering what's the best way to approach an online article system that allows users to comment by clicking on the line they are commenting about? Essentially the same way Adobe Acrobat works with comments where you can click anywhere and the text is saved for that location.

I'm assuming a mix of jQuery would be the crux of the interface. The system would need to save comments so that when another user logs in, they will also see the other comments but they can´t edit them - only add their own.

Any suggestions would be great.

C# Line Indexes in RichTextBox



Im making an application in C# and it's my first time to make one (and a big leap from Turbo C++) and Im having a great time for the past 5 days that is until I couldnt figure out how to go to the next line of text immediately following a search. Here are parts of my code

The search is done inside the richtextbox "ImporterTextBox", text is transferred to a textbox(multiline) "NETDevices"

The text file being read is a generated report from a diagnostics software


string NAData = "Network Adapter";    
searchindex = ImporterTextBox.Find(NAData); //sfc Network Adapter info lineindex = ImporterTextBox.GetLineFromCharIndex(searchindex); TempString = ImporterTextBox.Lines[lineindex]; TempString = TempString.Replace(NAData, ""); TempString = TempString.Trim(); NETDevices.Text = TempString;

 The text below is a sample of a section of the generated report which my application should read

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

I am working on a project currently where I need to get data out of a 3rd party vendor's software that uses a .sdf file I looked this up and its a SQL CE file. I was hoping to just link to with with access but thats apparently not going to happen. I need to link to the database extract data from it to a csv file for later use. I also and most important I need to get the data from it and create a report that can be printed while on a customers site that my or may not have web access so I need for this program to be on and off line. I had my webapplication that I have been working on open and was able to bring up the sdf file under the server exploere however I can't seem to get anything out of it when I try to do grid views or detail views errors out.

Can I use one of Visual Studio projects to create this sort of applicaiton if so what would be the best approach. I would love to get an access odbc driver since office is allready installed on the employee's laptop's

crystal report -visual studio 2008 dual axis chart (bar & line)


dear all, 

i use crystal report integrated with  vs.2008, and i want to make chart with dual axis (bar & line).

i have used bar chart and input the data with 2 values..

then in chart options > template, i activated the dual axis..

my question is, how i can change the 2nd value with line chart not bar chart??

i'd tried to find the right settings in "chart options" but still can't find the solution.

for information in "chart options" there are 4 sub menu : template, general,titles,grid..

i read in a tutorial there's more sub menu called "series" in crystal report (stand alone version)..

is it possible doing it in Crystal Report VS. 2008?

please,, i need your advice and solution..

Thanx before..
