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 a table that include a current year data and as well as previous data to be compare. here is the example of the table that i want to create: but i want to compare one of the annual data with the previous year. as example i want to compare between the data of current AR of 2007 with the current AR for 2006, Current AR of 2006 with current AR for 2005 and go on~, but i have no idea how to do it.
I want to enlarge an image, possibly up to 32 times or 64 times bigger than original dimensions (so that the user can see each pixel) if possible. The following is a simple function that I have to enlarge an image.
Private Function xEnlarge(ByVal Source As Image, ByVal Rate As Double, Optional ByVal Quality As Drawing2D.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic) As Image
I have a button where I get data from a database that matches a search string I enter. Everything works fine the first time the button is clicked. However, if I click it again with a different search string, I get the same results as the original search string. I've tried to dispose, clear, and reset my dataset before I load the data each time, but it still finds the original query. This is the code I use to get and request the data:
Private Sub btnCfind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCfind.Click mdbFile = "TCICUST.DBF" mdbCond = " WHERE COMPANY LIKE '" & cbCust.Text & "%' ORDER BY COMPANY " GetDB() [Code] .....
I want to search data and then populate on a datagrid. I write the name and I click the button and it does work well, but then if I want to search for another name, I write the new name and when I click the button again the datagrid comes empty. No data at all. I will put my code'[code...]

I am displaying data in DataGridView. When I am just adding a record at runtime, the new record gets add, but previous records are getting displayed two times.I tried to remove the rows which are displayed before adding the new row. But then new record is not getting displayed.
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'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
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 wish to avoid duplicate files using content based in any drive. Files may be at any formats . I dont know wat algorithm s used for fast search and how to compare all data formats.

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 was just wondering if there was a way that i could compare data stored in a text file such as usernames and passwords with data input into text boxes in visual studio vb2008?
I'm just trying to implement a 'no duplicates' catch on my insert customer form, but it just slips through my if statement to the else everytime. This is the source. Also I tried a .Equals with the same results :(

What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?
how to compare 2 sql tables and show data that are in table 1 but not in table2?

i have tried google and other sites.. but still cannot find solution. maybe i post the wrong question. but i manage to do this code. but its only shows only 1 record missing, but its supposed to show 5 records that r missing.
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.
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.
they need to make some compare version between host version and client version.. and each 1 version different will download the file to the client..[URL]..with both example, how can i make a program in VB.NET just like i said just now?
