VS 2008 - Reading Contents Of A Text File Into Text Box On Form
Jul 13, 2011
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.
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.
how to read the data's in the text file using sql server 2000 and 2008. i have a text file in a server and it contains one column name with the multiple column values i need to read that informations and i need to update in a table in the database.
im currently trying to create a blog using c# and xml. ive created the form and code that allows me to write the data inputted to an xml form and now i want to display it in another page. can anyone tell me what to do?
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 need to display the contents of a file selected from a ListBox into a text box. When I populate the ListBoxItems, I set the Text property to the name of the file and its full path to the Value property.
When I click the item, the page refreshes because AutoPostBack is on, but nothing happens. I then tried this:
VB.NET Code: Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged Me.txtServiceTag.Text = Me.lbLogs.SelectedItem.TextEnd Sub
I'm working on an application (ASP.NET, Webforms) that generates a list of outputs based on a user input. I want to allow the user to save the contents of said list as text file, or possibly as other filetypes such as .csv. What is the best way to approach this? Can it be done client-side with Javascript?
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

I want to change the color of my background on a textbox when the user typers stuff. For example I have two textboxes password and confirm password. On the second one if the passwords match I'm going to make the back color white if not red.
I can do this on WinForms easy as, same code on Web Forms and nothing happens. How do i do this???
First of all, feel free to move this thread if you find it inappropriate for this section of the forum. I placed it here since I intended to use ASP.NET.
So here's my concern...
How do you retrieve a text file from a UNIX workstation? This text file contains information structured like a table (or like a database). I need to create a custom report (in a Windows PC) based on that text file.
I'm using a log file to document info while getting and processing info from a form
1. if not post back, open the log file, build page, send form. 2. get submit back from form, possible post back if errors, possible writes to log file, if no errors definitely writes to log file, and send confirm page. 3. postback from confirm page can either be going back to form or finalizing, and send acknowledge page, then done.
so I need to keep the logfile object between direct postbacks to the form, or posting back to orignal form page after gettting a postback from a confirm page.
this type of file setup works fine, it creates a single log file per day:
[Code]....
then successive writes are like this:
[Code]....
when the form submit comes back from the original send/submit, lf from above is 'nothing'
saw the post about 9 ways to maintain state, not sure at all which would be most appropriate to keep the lf object accessible between possible postbacks and submits to the form.
I have an old database that still contains depreciated Text fields. I need to pull from these fields and display the results. You would think this should be easy... First my select statement caused a problem:
Code: SELECT DISTINCT ..., CustomerInstructions, ... FROM Orders where CustomerInstructions is a Text field.
The error I get: "The text data type cannot be selected as DISTINCT because it is not comparable." A quick search shows I can cast the text field as a varchar(max).
Code: SELECT DISTINCT ..., CAST(CustomerInstructions AS VARCHAR(MAX)), ... FROM Orders
Now I get an error while trying to load the instructions into a text box: "Specified argument was out of the range of valid values. Parameter name: index"
Not sure what the problem is here. I have text and a text box. What's with the "out of range" crap?
I need to fetch first 75 data or lines and insert in the sql table. Again next 75 data or lines and insert in the sql table. Again next 75 data or lines and insert in the sql table until it finish all.How i can do it in ASP.NET with C#
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.
Where is the event! 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.
I want to save the text data that coming from the database into the Text files.Suppose if i have dataset that contains 10 rows then i want to generate 10 text files and each text files contains associated row data.Finally i want to save them in the folder.Mail all the text files as a compressed format like zip and send them to the user.
eliminate a comma when reading a sales price from a text box.
Dim SPnc As String = Regex.Replace(txtValue.Text, ",", "") Value = Convert.ToSingle(SPnc)
However, I am still at a loss to find out how to eliminate the $, which I believe is a metacharacter with a special meaning. If my user enters $100,000, the value is read as 0.

How can this be done? The .InnerText Property (when used on the containing div element) is giving me the html only. Is it possible to iterate through all the li elements contained and extract their values?
