Web Forms :: Reading Text File Into Multi-line Text Box
Oct 12, 2010
I have an input type, so a text box which has a browse button next to it. When it is clicked, the file that is selected has it's full path placed into the text box.
Now that I have the path to the file in the textbox of the input type, I want to load each line of this file into a textbox that is able to handle multiline text.
I don't want the file to be uploaded to the website. I just want to contents of the file read and placed in a textbox all with one click on the browse button.
F|70.5|48.1|-999.9|-999.9|-999.9|-999.9|72.2|44.3|-999.9|73.4|38.1|-999.9I first want a way to read this line so i can write it with response.write. how would i also break those figures up by the"|" so the array would only store the numbers?
how to disable the resizing of a multiline textbox control. I'm trying to use the textarea to display rules for a contest, however I dont want them to be able to change the size of it by dragging it around from the bottom right corner.
I insert a text box, change the parameters to multi line and then pass the string to sql. Users insert comments etc, using line breaks, however because I just pass this as a string the line breaks are not there when they view the text box after input. Example: Here is a well formatted comment. as I typed in the text box today. Inserted in to sql as a string, returns this on select:
Here is a well formatted comment.as I typed in the text boxtoday. How do I insert the line breaks in the string from a textbox?
I have a web form that has a few multi-line text box controls which the user will enter lots of information in paragraphs. How can I persist their line breaks and tabs into SQL 2005 so that when the information is retrieved on a different page; the line breaks and formatting is preserved?
I'm trying to read the contents of a text file into a text box on my form. When I run the following code, nothing happens.
VB.NET Code: Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged For Each li As ListItem In lbLogs.Items If li.Selected Then Using sw As New StreamReader(li.Value) txtLog.Text = sw.ReadToEnd sw.Close() End Using End If Next End Sub
I populate the ListBox with ListItems and each ListItem's Value property holds the full path to the file. But, I removed all of that and just put txtLog.Text = "test" inside of the "is selected" block.
What i have on my asp.net web page is a drop down list a add button and a mutiline text box, what I am trying to do is when user selcts a item from the drop down list it should populate in the multiline text box, I am able to achieve this partially with the multiline text box only showing the latest selection it does not remember the previous selection. Listed below is the code behing page
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { jtOperationsddl.DataSource = sqlServer.GetOperationsForDataEntry(); jtOperationsddl.DataValueField = "OperationID"; jtOperationsddl.DataTextField = "OperationName"; jtOperationsddl.DataBind(); } } protected void btnAddOperaions(object sender, EventArgs e) { listofOperations.Add(System.Convert.ToString(jtOperationsddl.SelectedItem)); String s = null; for (int i = 0; i < listofOperations.Count; i++) { s = s + System.Convert.ToString(listofOperations[i]); } jtOperationsmltbx.Text = s; }
Every time I hit the add button the List becomes empty

I have read plenty of tutorials on taking a datagrid to a text file, but I haven't seen anything about taking a single cell from a datagrid, formatting it, and writing it to a text file. Is this possible, am I going about it wrong?
I'm trying to read data from a text file into a DataReader object using the following code but I get an exception:
OleDBException was unhandled.
Cannot update. Database or object is read-only.
Also, I would like to know if it is efficient to read data of a text file into a datatable instead of using StreamReader object and traversing through the recordset.
I know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?
I have long CSV file that I would like to read data from, save them in a database and delete the last line. I have been trying to get this fixed but I do not how to. how to do this. C# code would be great but VB wouldn't hurt.
Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene
