Mar 15, 2012
Im using visual studio 2005 and access 2007 as database. I have already connect the database which have two table with two gridview in a web form (asp.net). Now i want to compared the data in the two gridview, and those who are matching should be displayed in a pop up Text box. All this should be done by clicking on a single button.
The following is the codes which i have tried and it does not work. I dont know where the problem. The following codes are for those who does not matched, which will be display. please answer should be in vb.net not C#
These codes are found inside my button "compare"

I have a gridview(editable).
It may have more than 1 row with columns startdate and enddate.
StartDate EndDate
4/4/09 6/6/09 (valid-existing row)
1/2/09 3/3/09 (valid-existing row)
7/7/09 9/9/09 (valid- edited row)
3/3/09 6/6/09 (Invalid - edited row )
When you see the above table/gridview, you will know what I want to validate.
I should be checking whether there is any row having start-end dates lying within the existing date range, if so I should invalidate them.
I shd have only distinct date range in my rows.
How do I do that.
May be Useful note: I will be able to check which column name I tried editing in that row.
Do any of you have some ideas how to create a logic to accomodate my validation issue in my webbased gridview control ?

The user will click the book name in the combo box.
Note: The combo box is separate from datagridview . It is not part of datagridview columns.
Then the datagridview for Issuing books i.e. with the columns bid,bname,aname,data of issue,date of return should be displayed.
The row that will be displayed in datagridview is such that the bookname selected by user in the combo box should match with bname row .
On the same datagridview there will be button with name "Issue" so once it is clicked then this whole data of datagridview should get stored in the database table name "Issue" and get deleted from the databse table name "MBA"

I have users check off lab facilities in a UI. I want to use linq to fetch corresponding records for all of the labs that they have checked off. Basically,
Dim myRecs = (From l As EpiData In myDataContext.EPIDatas Where l.facility= _
one of the checked labs
So basically, I need to write a linq query where the "strings" to match are determined at runtime. Is there any way to do this easily? I know that there is a library out there called dynamic LINQ, but (1) it's in C# and I'm writing in VB (2) I'm really just looking for a single, simple solution for this single case.

I have a gridview with two cells cell(0) is a IP-number and cell(1) is a resultTxt. I have X number of rows. I want a solution that check each row and do a ping to the ip and write result to result. I want to do the ping in a new thread and i want to be able to do more then one at the time. So I want a loop that keeps checking the ones that are not online until they goes online. It's the thread-part I have questions about, looping gridview and doing a ping I can manage, but it I don't do it in a thread the interface freezes.

In my form I have four text boxes (2 in each row); Textbox_FN1, Textbox_LN1 in row 1 and Textbox_FN2,Textbox_LN2 in row 2. When a button is clicked; I want to pass the row number to the following procedure which needs to read values from two text boxes and write to DatagridView. The code below writes the literal "Textbox_FN1.txt" but I need actual value from the textbox control.

I'm still trying to understand and use Use Cases and Test Driven Development, but having a hard time crossing the line. I'm hoping someone can provide a good example of how setting a datasource and/or databinding a gridview could be accomplished using Test Driven Development. Here is my pseudo approach at it.

I have a modal popup that contains a gridview. On the click of a button inside of a grid i reload the gridview with the data that depends on the id of the row clicked in the gridview. I would have like to reload the gridview onclientclick but I couldn't find a way to do that. Is it possible to reload a gridview client-side without the user even knowing the page partially loaded?

In a partial class, I declare a integer. Then, depending upon if a criteria is met, I set it's value to either 1 or 0. Then, I try and compare the set value, but instead of it being equal to 1 or 0, the code behind that I've stepped thru shows it ends up equaling &H0 or &H1. What does that mean? Why does it show a value of &H0 in the code behind when I debug instead of either a 0 or a 1???

First my prog scan a specific path "C:music" which contain Mp3. Then it takes the MD5# of all mp3 and put it in a listbox1. Also on the formload it does open a ".txt" which also contain MD5# that goes into listbox2.Now this is what i am looking to have :When i click my button it compare each line of my listbox1 to listbox2. If , for exemple , the first line of listbox1 is already in the listbox2 then it delete the first line of listbox1 (listbox1.items.removeat(0)). And Do until listbox1.items.count = "0".

I am trying to carry out a synchronisation of two databases: one on the server and the other on a local machine. So that even when they are not connected on the network, the local database can carry on accepting data but when the network is back on, the local database can update the server and the server can also update the local machine with data it accepted during the time when the network was off. by first comparing two tables in two databases and then if they are any differences the updating begins and i've since been stuck.
Private Sub btnCompareTables_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCompareTables.Click

I want to track changes of a document which sits in a DB table like :
document starts
document continues 1
document continues 2
document continues ...
document ends
(Each line is a record but if needed I can combine them all to one record)I have the document before changes in one table and the document after the change in another table.My problem is that if I just compare them by ID then I'll get many more changes than actually occured. Ex: If a line (/record) was added between record 2 and record 3, instead of tracking 1 change I will see that all the records from 3 and on have changed (because they will be pushed off by one record). Can be also something which knows to compare documents and I'll take the information out to document for comparison.

Let me provide a little detail to explain what I'm trying to accomplish before I get into the nuts and bolts of the question. I've got two data sources - one is a SQL Server containing part numbers, descriptions, etc. The other is a CAD system that does not have a database in a traditional sense. What I'm trying to do is read out the bill of materials from the SQL Server and compare it to the CAD assembly drawing to ensure that the CAD system contains the same information as the SQL Server.
Getting the data from the SQL Server is fairly straight forward. I query the database and populate a datagrid. Done. Quick. Easy.Getting the data from the CAD system is a little more involved. I have to load the assembly drawing to get a listing of all the component parts and then load those individual drawings to pull the "Part Number" property from the drawing. This is a somewhat time consuming and slow process (unfortunately) since each of the files must actually be accessed. I load those properties into an array (I guess a list might be more efficient).
So now I have a datagrid and array with part numbers. I need to compare them and colorize the grid accordingly. The grid should remain transparent if the part exists in both, color the row yellow if it only exists in the grid, and add a row colored red if only in the array.
As best I can tell, this means looping through the array on each line of the grid. The thought process is this:Default the grid to yellow rows.Loop through the grid and loop through the array to compare. If a match is found, make the row transparent and delete the element from the array.After step 2 is completed, the array should only contain elements that are not found in the grid. Resize the array to remove the empty elements.Add the elements of the array to the grid and color those new rows red.The problems with this logic is that it seems expensive from a performance standpoint. Surely there is a better method? Also, if I modify the grid in some manner (like a resort) I have to go through the process again.

I'm working on a Website in Web Developer 2010 where the content of a text box is checked against a list of values to find a match. There must be an exact match for the user to be allowed to proceed to the next step of the wizard.
Is there a shorter method to do this using the VB 'If' statement, other than specifying each condition individually?
I've tried something similar to the following, but for the amount of values it would be more practical if there was a shorter method.
If TextBox1.Text = "User1" Then
Label1.Text = "Ok, That username is valid. Click NEXT to continue"
LinkButton1.Enabled = True

I am a c#/asp.net developer and I am having to work on a VB/asp.net. I have two variables
Dim originalDate as DateTime?
Dim newDate as DateTime?
Both nullable datetimes, originalDate is a nullable date I am getting from the database and newDate time is set in code, I need to compare them, they can either both have dates, neither have dates or one have and one not.
I have a bit of code as follows:
if origEndDate = origEndDate then
When both origEndDate and origEndDate are "nothing" this statement is false (well when I run it in the watch window it comes back as nothing)!I don't understand why this is the case because I was under the impression doing an "=" compares the two values and as they are the same surely it should be true? What syntax should I be using as in C# I can do the above as so:
if (origEndDate == origEndDate) { }
and it will come back as true.
