View 6 RepliesI am having difficulty writing to cvs files. My application is a text parser that scans a txt file, removes punctuation, and then stores the individual words in another txt file for later analysis. My end aim is to process txt for semantic similarities. I'm very new to this so my code is very chunky But I'd really like to pull each sentence from txt file, put into an array, and then place each array item into a CSV file with commas between words.

View 5 RepliesI'm trying to read data from a text file with multiple records and fields separated by tabs to store into arrays, which I later want to output into a textbox on the form. The problem is that with the code I've written, when I debug it it exits the sub procedure when it enters the first loop where the parser is reading the text file. There are no error messages, it just exits? I'm not even sure if what I've written is possible. Here's what I've written so far:

View 1 RepliesI have two text files with various columns, each column is separated by a tab (" "). What I'm trying to do is the following:-If the values in text file 2 column 1 does not contain any value in text file 1 column 1 then add that field to text file 2 and add a 1 to the second column, like so
String 1 If the value in text file 2 column 1 already appears in text file 1 columns 1 then just add +1 to the value, so if the above value is already in Text File 1 Column 1 and Text File 2 Column 1 then it would appear as.
String 2 And if it was to happen again then
String 3 and so on.I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
IO.File.WriteAllLines("File2", lines1.ToArray) & +1)
[code]....
I use the above coding, but it removes the second column?

View 5 RepliesI'm trying to simply prove here that this simple function isn't good enough to prevent every sql injection in the world:[code]I know its not secure, because of googling and looking up other questions on url...[code]I then coppied a Chr(8) from the clipboard and replaced the Chr(8) in the textbox with the clipboard contents and still a no-go.It puts the whole string directly into the field w/o problems.I'm using MS SQL Server 2005, and VB .NET 2005.the Text1 field in the database is a Varchar(600) field (don't ask my why its not MAX, its pointless, i know)There are certain triggers on the table that would prevent a mass update such as this and throw some errors if the injection actually worked right.I know parametrized queries are the way to go here and I'm not looking for answers like "well i dunno why it doesn't work, but parametrized queries are the way to go".I'm looking for the ability to prove that our software is broken and that we need to rewrite it using better principles.how to better filter your text fields, the answer is DON'T! Use the parameters! they are much better, safer, and easier!
View 5 RepliesI have a txt field that is used for comments that is stored in a SQL Varchar(max) field. No matter what I put in there it always is limited to 50 Characters. I was told that it was unlimited pretty much. I need to be able to put in up to 200 characters.
View 6 RepliesI'm working on this project, and when the form loads it should automatically put the Focus on the username field if it is empty, however if there is a username - put the focus on where you write your message.Below is the code, and it simply doesn't seem to work for whatever reason. I have tried several methods of it, and even commented out every other line of code in the application to make sure there was no interference, and there was none. is there anything that could possibly overwrite the ability to do this? Some setting I need to change? etc etc?
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If String.IsNullOrEmpty(txtUser.Text) Then
txtUser.Focus()
Else

I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")
Dim*SaveTextFile*As*String*= IO.Path.Combine("C:Test2.txt")

I have text field that a user enters a date in. Based on what they enter a drop down box will appear or not appear. To obtain the info for the code to control the drop down I am using an auto post back on the text box. This is however making the app a bit clumsy as the user is taken back to the top of the page.
View 2 RepliesIn my page there is a fileupload control and a gridview. When I upload a file, the DocName and the path of the saved file will in the gridview. I put the filepath in a hyperlink field so that it will show "View file"(not the path). My problem is - the gridview is showing "view file" text when there is no file saved.It works fine when I upload a file.
GridView :

asp:GridView ID="gvFile" runat="server" AllowPaging="True" AutoGenerateColumns="False"
DataSourceID="odsrcInsertUpload" Width="552px" BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal">

I have been trying to figure out how to take text i have in a SQL text field and create the correct document from it. Here is the info i have in SQL: MIMEType is a string field that contains one of the following "application/pdf", "application/msword", "application/vnd.ms-excel" or a few others. DocumentBody is a text field that looks like "0M8R4KGxGuEPgADAP7/CQA" this continues for quite a bit. FileName is a string field that contains the original file name such as "test.doc" or "test.pdf"
I have tried using the System.IO.FileStream and System.IO.StreamWriter but in the document it actually writes the text that is desplayed in DocumentBody. I assume I am missing some way to decode this using the MIMEType but i just can not seem to find it.
What I need to do is query an iTextSharp AcroField to check if it is rotated, and if so capture the value of the rotation.So If I have the following field:
Dim af As iTextSharp.text.pdf.AcroFields = stamper.AcroFields
Dim afi As iTextSharp.text.pdf.AcroFields.Item
afi = af.GetFieldItem("fieldName")
What do I need to do to get the rotation (in degrees) of that specific field?

I'm trying to design a words game that's give you the first two letters from the word and you insert the rest to make a word (for now I'm just using "co" as example and I have just one table in the database for it). The word will be written in textbox to be compared to a database field. If the word exist in the field the word will be displayed in a label with blue color and the score will increased by one if not the word will be displayed in the label with red color. This should happen three times with three words and I have different label for each one.
the name of my database is database1 and it have one table "A" wich contain "Comp" and "word". I tried this game with array of word before and it was working. Now I'm trying to use database instead of arrays but its not working. [Code]
I am trying to remove all spaces from a text field when a form is submitted so that the contents of the post code field match those in a database...
If drSet5c.Tables(0).Rows(0).Item("post_code") = UCase(Replace(tbPostcode.Text, " ","")) Then
response.write("Postcodes match")
[Code]....
So if the postcode in the database is AB12CD and the user types AB1 2CD the space is removed on submitting the form and the match statement shows. This is not working though.
I have some coding which displays a label if the value of a textbox matches any of the first values of each line in a textfile.[code]....

I'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.For example, I have 4 textboxes currently that have Address, City, State, Zip.I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID. How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.
