Asp.net - Saving Text Data From SQL Server To File Directory Using Asp
Mar 15, 2010
A variety of files (pdf, images, etc.) are stored in a ntext field on a MS SQL Server. I am not sure what type is in this field, other than it shows question marks and undefined characters, I am assuming they are binary type.
The script is supposed to iterate through the rows and extract and save these files to a temp directory. "filename" and "contenttype" are given, and "data" is whatever is in the ntext field.
I have tried several solutions:
1) data.SaveToFile "/temp/"&filename, 2
Error: Object required: '????????????????????'
???
2) File.WriteAllBytes "/temp/"&filename, data
Error: Object required: 'File'
I have no idea how to import this, or the Server for MapPath. (Cue: what a noob!)
This works, but the file should be saving to the server instead of popping up save-as dialog. I am not sure if there is a way to save the response to file.
Currently I am saving data from my applications by saving a text file via a stream reader as a string. I have come to a problem. In my current application, I have an array of the following structure:
I have a sign up sheet that I am creating for a project I'm working on and the sign up sheet works and I can enter all my data into the text fields and save the info but when I go to open the file again all the data is pushed into one text box and not in their own fields?
If there a trick in the SaveFileDialog that I can use to save each field to file then open them back in their own field?
Here's a screen shot of the before and after the program [URL]
1) How can I load data from Text file to DatagridView. I want it because I'm making a listener. And when I load a data from text file, i want to edit rows. And this calling the second question. 2) How can I save data, Datagrid to Text file.
I found a code Dim obj_oledb_da As System.Data.Odbc.OdbcDataAdapter Public Function ConnectCSV1(ByVal filetable As String) As DataSet Dim dataSet As New DataSet [Code] ..... I can load data with this code but I can't save.
My Text File must be like this: #IP 127.0.0.1 localhost
below the form i have a button that saves the data to a text file called 'mailinglist.txt'
So i enter the data into the fields and click the button like as follows:
Full Name: John Smith Amount Contribted in �: 40
However..... when i go view the text file it displays John smith40, which i want a space between the name and the numeral.
Also as i want a maximum of 5 people added to the mailing list, i would like a function that lets me somehow "adds" an extra 4 people to the text file without overwriting the 1st name, and uses the same "current" form displayed to the user.
Here is the code as follows:
Public Class Form2 Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
I'd like to save data to a text file on a remote server I have. There are no security issues here, just the method.
Dim FILE_NAME As String = "123.456.789.012/variables.txt" If System.IO.File.Exists(FILE_NAME) = True Then Dim objWriter As New System.IO.StreamWriter(FILE_NAME)
[Code].....
I know it's not the most secure way of doing things, but the end data has to be in the txt format, otherwise I'd have used MySQL.
I have binded a textbox to a column in a SQL Server 2005 Database, when i fill the dataset it displays the data, but when i click the save button it doesn not save the changes to the database. I used this same code to do a Datagridview and it worked fine. [code]
i am trying to save data from vb.net form in sql server 2008 below is the code which i am using but the only problem is . i am not getting any error instead the data which is being saved in sql server in my First Name , Last Name and Address fields is not the one i insert into textboxes, when i check the backend it shows me my field values as first name , last name and address.
Dim FirstName As String Dim LastName As String Dim Address As String
I have a string with Binarydata that is 64bit. I want to store this data into SQlServer database and the column is varbinary(Max).When I pass the string I am getting an error saying string cannot be converted into varbinary.
I am trying to save(export) data from a table in sql 2005. the version of office used is 2007.
I through something together quickly, thinking it would work.. but now I am not sure why its not.? everything seems to work, no errors or anything.. just no excel file either.
Try Dim strfilename As String = "" Dim intOpenResult As Integer = vbOKCancel
My web and sql db are on two different servers. I'm developing a component in my vb.net web app which uses sql dbmail to send mail. That part is already working but part of the requirement is to allow the users to add an attachment to their email. SQL dbmail requires an absolute path for the email attachment for example, in sql:Declare @Attachments nvarchar(max)
Select @Attachments = 'D:emp ewreport.pdf'So currently in my vb code I have the following:
how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)
I have a textbox that is filled with some carefully formatted text. I need to save the text in that textbox as a text file with the extension of '.scr' eg: File1.scr instead of File1.txt
This is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.
Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.
Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?
rewriting a class I use for saving Treeview data to a XML file for use of saving ListView data I can't really figure out the rewrite, I'm stucked, unfortunately Listviews seems to be a big problem for me in general.
Option Strict On
''' <summary> ''' The TreeViewDataAccess class allows the nodes within a TreeView to be ''' persisted to xml for later retrevial. ''' </summary>
I have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked. [Code] So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.
i am making a quick program that will test the anti-virus on any computer. i am using the EICAR test that was developed by European Institute of Computer Anti-virus Research. so in order for this test to work i need a code
(X5O!P%@AP[4PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H* ) to be pasted into a new text file and saved as myfile.com.
so I need to know how to create a new text file and past the code in and save it as [URL]
This saves a bmp with nothing in it Dim bmp As New Bitmap(PictureBox1.Width, PictureBox1.Height) PictureBox1.DrawToBitmap(bmp, PictureBox1.DisplayRectangle) bmp.Save("C:UsersXXXXXXXXdocuments estingoftheimage.bmp", Drawing.Imaging.ImageFormat.Bmp)
arrays saving to file that if new user account is added name and email address is saved. if in the future multiple users login in whe name and email address will match correct users.
here is what i got so far....
Public Class Form1 Public strName, strSurname, strEmail, strPassword As String Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
