Compare Data From A DataGridView

Dec 14, 2009

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?

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

Compare Times Only In Data?

Nov 17, 2010

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.

App To Compare Data From Various Text Files

Dec 7, 2010

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.

App To Compare Data In Various Text Files?

Dec 7, 2010

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.

C# - Compare Two Objects Regardless Of Data Types?

Oct 12, 2010

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

VS 2010 : Compare The Data Between Two Text Boxes And A Variable?

Feb 27, 2012

I need to compare the data between two text boxes and a variable. If the value of the boxes don't match up and the variable is -1, I need to fail it.When I do this:

VB.NET
If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text Then

I have no troubles, but adding the variable check produces a false positive.

VB.NET
If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text And TestData.BypassCheck_PCID = -1 Then

The way the code is laid out, I have to do this in one line. I can't check the first condition on one line and the second on another.I've tried separating the data out with parantheses, but it's producing the same results.

Forms :: Integer Value Changing When Compare Cell Data By Using 'IndexOf' Feature?

Sep 17, 2010

I have a program that is reading an Excel (xlsx) file and I am trying to take the data found in one of the cells and split it based upon the '@' symbol inside that cell. Here's an example: value in cell is "XXX @ YYY" I declare 3 strings (strOriginal, strA, strH) strOriginal is the value from the cell ("XXX @ YYY") then my code is supposed to split up the values in the Original string based upon that '@' symbol.So when my code is done, strA should = 'XXX' and strH should = 'YYY'.

Here is my code

strOriginal = dtbExcelData.Rows(0).Item(0).ToString
y = strOriginal.IndexOf("@")
strA = strOriginal.Substring(0, y - 1)

[code]....

For some unknown reason, the y integer (in this case, it is '4') changes to a random number (it has changed to 44, 61, 124) and causes the error "Error with Excel file: Index and length must refer to a location within the string. Parameter name: length" to occur.I understand why the error occurs (my y integer is not staying at 4)...I just don't understand why that y integer is changing numbers when it should remain as the indexof the '@' symbol. I'm looking for any suggestions on how to pull out the data after the space after the '@' symbol (the 'YYY' portion of 'XXX @ YYY'). Also sometimes the 'YYY' is only 'YY' as well.

Dont Get Any Data From Socket When Data Should Be There And No Exeptions Raised, Connection Is Open. Using DataAvailable To Wait For Data

Mar 24, 2011

I have a problem reading data from an RFID-reader. I connect to the reader by tcp and wait for DataAvailable to be true, then reading the data until I got a end of data character. Then I just go back and waiting for a new DataAvailable. This is done in a own thread for the function.

There seems to be some kind of timeout, If I don't got any data in a couple of minutes, then it just sits there in the do/loop waiting for DataAvailable. I hold the card to the RFID reader, it beeps, but there is no data available. I don't get any exeptions, and the information says that the clientsocket is still connected. Are there anything more I can check?

If I put the card to the reader in a minute-interval it seems as this will never occur. So 2-3 minutes idle:ing seems to do this.

Here are my code to read data from the socket, I have taken away some irrelevant code:

Sub test(ByVal ip As String, ByVal port As Integer)
' this sub is meant to run forever

HSD 32 Bit Data Bus To Serial Converter Via A Microcontroller - Data Sniffer To Read The Data Bus (32Bit)

Sep 3, 2008

Im working on a HSD 32 bit data bus to serial converter via a microcontroller. Now first I want to make a sort of data sniffer to read the data bus (32Bit) .All on the controller side is working and the stream of bytes are coming in via RS232 as 4 bytes in HEX like FD,A5,45,8B . I already converted the bytes in Dec and ASCII to determine what is passed true the bus and how fast and stuff.. Now that is all correct and working very well if the LSB (least significant bit) of the 32 data bus is Data line 0 and the MSB (most significant bit) is Data line 31 but if that is not the case I need to invert the 32Bits (like as I would invert the connector on the bus) . How do I best do this using the 4 bytes I send from the micro controller.

Example:

(MSB) 01001000 01100101 01101100 01110000 (LSB)
HEX= 48 65 6C 70
DEC= 72,101,108,112
ASCII= H E L P

I need to invert it with a button to:

(MSB) 00001110 00110110 10100110 00010010 (LSB)
HEX= 0E 36 A6 12
DEC= 14,54,166,18
ASCII= (SO) 6 : (DC2)

Update New Data With The Previous Data If The New Data Equal To 0?

Sep 11, 2010

I am having an issue on the listbox when the new data value equal to previous data then = to "0". However, I want if the new data value( A ) is equal to the previous data( B ) then ( A ) equal to ( B ).

Delegate Sub ListBoxUpdater(ByRef listbox As ListBox, ByRef str As Object)
Private Sub OnQuoteUpdate(ByRef QuoteUpdate As LingLib.structQuoteUpdate)
UpdateListBox(lbBox, QuoteUpdate.tQuote)
End Sub

[code]....

My problem is when the new data comes out from the API, if it is equal to the previous data and it will appear 0. But what i want is the new data comes out is 0 and it will equal to previous data. e.g: first data comes out is 12.00, in above case, if the second data comes out is 12.00 but it will shows 0 which means unchanged. But in my case now, i want if the first data come out is 12.00, then if the next data is unchanged (0) and it will appear 12.00 and so on.

Saving Replicated Data - Current Data Saved To Appear In Page Within All The Relevant Fields?

Jun 2, 2010

What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.

e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.
