How To Filter Text Field
Dec 2, 2009
I'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!

I have a database that I would like to filter characters from anywhere in the field. Example the letter A is typed into textbox1 and in the grid every field that contains an A is show. Like dash, lap, trap, apple. Currently with the query I'm using it will just go from the beginning of the field. I get "Index was outside the bounds of the array". The code is as followed:
Dim filter1() As String
filter1 = TextBox2.Text.Split(" ")
Sheet1BindingSource.Filter = "Stationary_location like '" & filter1(0) & "' Stationary_location like '" & filter1(1) & "'"
VB 2008 using access database.

I'm using EPPlus to create Excel reports. Now i'm trying to create a Pivot with a DateTime PageField, so that the user can filter the period he want to see by himself. But although i can filter this for year,month or days in the according data worksheet by default, i don't get it working in the Pivot.
Here is what i have:
Dim wsPivot = excel.Workbook.Worksheets.Add("Pivot")
Dim wsData = excel.Workbook.Worksheets.Add("Data")
Dim source = workSheet.GetDataSource

I have a listview and a textbox under it. Whenever a user input's text, I want the listview to filter. The code I have works, but the listview doesn't load the filtered data. I think it's because the listview has 2 columns of data that it's loading. [Code]

I am trying to filter the results of a datagridviw using the bindingsource.filter method.
Dim filters(2) As String
...
If Me.txtPartIDFilter.Text = "" Then
[code]....
The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.

I have a database with a table that is a child to many other tables. I am using this child table as a datasource for a datagridview. I am using comboboxes to display specific fields in any parent tables, instead of the user seeing the foreign key. Everything is fine. However, I would like to filter the BindingSource based on text matches between any of the fields in the child table and the corresponding fields of the parent tables.

I 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?

I 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.

I'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 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.
