How To Implement A Read And Write For An Unknown Amount Of Rows
Jan 18, 2010
I asked a question similarly, but the outcome was pretty messy and I was having difficulties populating so I'm trying to go at from a different angle: [URL]
I have a table which stores steps in a process. Some companies only have 6 steps while others have 15, so I created a table with 15 different slots for steps. What I would like to do is set up a control that displays each step in its own row with a label next to it saying "Step '#'", and not in an adjacent column. I'd also like for it to not display any blank rows. If they are entering the step instructions, I would want for them to have to press a button that would add a row so that they aren't just given 15 empty text boxes to fill in.
What would be the best control to do this in, and how would I get started in setting it up?
I am doing some sorting of an array and in order to achieve that I have to declare bounds of a new array based on amount of results returned. So if I get 2 results I will initialize
tagArray = New Integer() {0, 1}, if 5 then tagArray = New Integer() {0, 1, 2, 3, 4}. The amount of results is unknown and it can be anywhere from 200 to 500 results returned. Is there a way to simplify this? I could probably hard-code it but that would look ugly.
I'm pretty new at ASP .NET but not to ASP. I've got a form I need to create where I don't know how many entries will be added. It has the following format:
"Age" "Duration" "Period of Duration" "etc..."
Last30Days
1-5 Months ago
6-11 Months ago
Age
Age
Age
etc.
So the Age column always has the first 3 options and then an unknown number of Age values that can be inserted. I've created a table that has the first four fields (Last30days, 1-5months, 6-11months, age) and I was thinking I could just order by those 4 columns for display. The problem I have is I'm not sure on how to proceed. Does anyone have any good ideas on how to handle this situation? Ideally data entry people could use the same form for both entering and displaying the data.

I'm working on setting up a Gridview that dynamically creates new "columns" after a set amount of rows. To do this, I bind a datasource to the Gridview and then add new cells and shift the other items into those cells. I seem to be having an error with the link buttons that I move around. All of the items get put in there correct location, but for some reason, when I click a link button that has been added to a new cell, the sender's text is the LinkButton in the original cell's text. Does anyone know why this would be happening? Is the gridview not meant to be manipulated after it has been data bound? This is the code that I use to update the gridview.
I'd like to write and read TCP Streams directly without any modifications by ASP or IIS. Is this possible?
Edit: Goal is to provide communication between a program and a server. Data exchange between them is less then 25 bytes per connection (in default case). So Headers will cause more traffic then the real data. I need to use ASP.Net because the owner of the server will not let me execute my programs.
I would like to use a file upload control and write the uploaded image to the user's asp.net profile property, and then read and display that image somewhere in my application.

Usually I use this code to read a file from beginning to end into a List<> and then I write to a file with the code I have above.It seems that StreamReader/StreamWriter is not possible to use in Global.asax.I simply might wonder how I can convert this code for Global.asax?
I'm trying to add functionality to a simple web service that will allow me to log information to an XML file on the hard drive where the application is located. When I employ the functionality in a Console version of the application, the data gets logged to:binx86Debug MySolution.MyProjectMessageLogTestMessagess.xml. However, when I try to write read from or write to the XML file in the ASP.NET application, I get a System.UnauthorizedAccessException with the message: Accees to the path 'MessageLog' is denied.I would like the log file to appear in the in folder of the application directory, so what settings in IIS or on the server itself would I need to change to allow my application to read from and write to that folder?
