Compare Data In Textbox?
May 6, 2012
I'm working on a project that will compare two textboxes and output the difference in a third textbox. To provide some background what I'm trying to do is compare a users active directory groups to another users groups. What I want this program to output is the groups the user already has, groups that need to be added, groups that need to be removed(basically unique values).comparing text will output an integer, or boolean. I need the actual difference outputted in text to have a working document of changes to groups.
Here is an example of what I want it do, but i'm only able to get it working using an excel macro.
Sub UniqueValues()
Application.ScreenUpdating = False
Dim i As Long

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

cmd = New SqlCommand("Select name from table1", con) Then
cmd.ExecuteNonQuery()

The above code is showing error in if condition. I don't know how to compare the textbox value with table row value by using if condition.

First I create a class which have a string property
Property stdName() As String
Then I open a text file and put into array of that class
Dim arrStudent() As Students
Dim allstdinfo As New IO.StreamReader(dlgOpenStudentsFile.FileName)
Do Until (allstdinfo.Peek() = -1)
Dim strAllstdinfo As String = allstdinfo.ReadLine()
Dim arrStudentLine() As String
[Code] .....
Finally I run a for loop and compare the stdName property with textbox.text
Dim counter As Integer = arrStudent.Length
(debug here)
For i As Integer = 0 To counter - 1
If (String.Compare(arrStudent(i).stdName, txtStdName.Text) = 0) Then
lblPhoneNo.Text = arrStudent(i).phoneNo
End If
Next
And I add watch:
Why the compare return 1

Again a little (for me) tricky thing:Supose you have a ComboBox control with predefined values - to keep it simple, let's add some colors:
- Blue
- Green
- Red
- Yellow
Now you have a TextBox control as well. If you type into the TextBox BLUE (non-key sensitive) I would like to make it recognize that this value already exists. It does not have to do anything else except for notifying me about a match.I do think that the TextBox1.KeyPress or TextBox1.TextChanged event is what I need but I have no idea how to compare to the ComboBox1 items. I've tried to create an Array of my ComboBox1.Items but didn't get much more than errors. Can anybody help? I am sure it is quite simple however, I can't get my mind set to go in the right direction

I've build a list of Strings from files. The list itself is working fine (tried it by having ListBoxes and other controls loading its items from there just to make sure that this is not the issue). Now, I am using this list of strings to compare a Text in a TextBox1 while typing to determine if this TextBox1.Text already exists in the list. I am using the following code (where "s" stands for my List items):
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.TextLength < "1" Then
Button6.Enabled = False
ToolStripStatusLabel1.Image = My.Resources.pic_Add_Warning
ToolStripStatusLabel1.ForeColor = Color.Red

I have a Data Table Column with multiple Rows of data. I need to search all lines of TextBox1.Text for any data that is identical to any row in the specified data column ("MCaddRG"). Also any identical findings need to be made into a new text file or a new form with a text box.[code]...
*Also if it is possible I would really like to have a check box list that contains the data from the "Device" columns so I could check the "Device" and then it search the TextBox.Text for the checked "Device's" "MCaddRG"

I am setting up a game for my final visual basic program in my computer programming class, and it is supposed to compare what you type into a textbox to a randomly generated password, and then return whether the last character you entered had a higher, lower or the exact same ascii value as the corresponding character in the randomly generated password. Well, in order to test it, I set up labels to compare the two characters... when you type in ALT + 125, the ascii value returns 125, as it should, and it says that the ascii value of the correct character is 142. I typed in ALT + 142, and the character's ascii value, according to what the label puts out, is 196... obviously its converting dec into hex or oct or something... but how do I fix it?I can also tell you that when I typed in 196 to see if it was reversed or something stupid like that, it printed that the ascii value was 49... what's up with that?!

I've been having problems with a really basic search routine that I have used successfully before but now for some reason does not. I have a text file that looks like this: Spindly Killer Fish, fish, spindly, aggressive, dangerous, grey, Sect.B Tank.1, 20 It is then loaded into a two dimensional array with comma separation. This is all fine and with the following nested for loops it works also, it just doesn't seem to compare the selected element with the textbox value. [Code]

I'm trying to figure out the best way to determine if there has been any data change to the actual database since my last data retrieval.I'm using a DataGridView to display the cache data to the end-user, but before they make permanent changes to the database, I would like to query the actual database to make sure that no updates have been made to the data source. I'm querying an AS400 system, so I have to use the OleDbDataReader object to retrieve data from the system. What is the best approach for this scenario?

I am reading data from a provider and they have a column where ONLY the time is provided. The thrid party provider cannot change the format and that is what i have to work with. An example
[11:56PM][516]
[11:57PM][510]
[11:58PM] [510]
[code]....
I can read the data no problem. The problem that i do have is to calculate the time elapsed between records. Here I can safely assume that at most the time will cross over into the next day. I don't particularly care what date I assign to my DateTime variable so i just pick DateTime.Now and then I go through and use the TimeSpan object to calculate time elapsed. Works great except when the records cross midnight.way to do just a pure time comparison? otherwise i am left currently with converting the time into a military time and then using a simple integer comparison to determine of the date has crossed over into the next day. i then use DateTime.Now.AddDays(1) to assign the full date.

i want to create an system that can trigger alert which, the alert box will change to a red color depending on its value.
my problem is, the value that i used to compare is dynamic and based on what user key in in the paramater table while the data that will be display the alert is from the alert table.
lets say the value in the parameter table is been declare as Aand the value that display the alert is been declare as cellvalue.
this is the code that i have been tryingif cellvalue < A then' some code to change the box colorEnd if
but i kept failing. the system cannot read the A value.

I've been tasked with writing an app that reads in various text files(.csv, .txt) in different formats with different delimiters.I then need to compare certain data in these files and report the differences.There are a couple of columns that are common between the files, but they aren't in the same place, and there is inconsistent and unnecessary header info.There is extra data(columns) in these files that I don't need.Should I parse these files into a datatable? Should I create an object for each file type to format the data and get rid of the unnecessary info?I'm not sure about the best way to tackle this problem.

I have been tasked with creating an app that will read in various text files(.csv, .txt) and compare some of the data contained within.
I thought I would read in the files and convert them to datatables. Once I had them in a datatable I figured I could remove the unnecessary rows/columns and then sort and compare the pertinent info for differences. The difficulty is that the various files are formatted differently so I will need to get each type formatted correctly. Is this the best approach?
I have read in a .csv, parsed it into a datatable, but I'm having trouble with the logic/coding to get rid of the rows and columns that I don't need. Also, I'm not sure how to handle a row that has a cell with a comma seperated list of values that will need to be split into individual rows.

I want to compare two objects whose type may be diffrent.
For eg, I expects 'true' for comparing 1000.0(Decimal) with 1000(Double) . Similary, it should return true if I compare 10(string) and 10(double) .
I tried to compare using Object.Equals() , but it did NOT work.It return false if two objects have different data types.
Dim oldVal As Object ' assgin some value
Dim newVal As Object 'assgin some value
If Not Object.Equals(oldVal,newVal) Then
