I am building an application that needs to compare data from 2 different ODBC sources. I need to compare certain tables, joined with other tables, with the same from the other ODBC. The table structure will be the same in both ODBC databases BUT the values will not. This is known.
I am looking for a method to best compare the data. Perhaps using DataTables, DataViews, or even XML? I am not too knowledgable about XML and the related functions.
Performance is important here, since there will be a lot to compare. However, output is also very important. I would like to show the record in the table that contains different values from the other database and also show the user the properties and values that were found to be different. How best to show this?
Really appreciate any help on this.
Thank you

If one of your data sources is in SQL Server, you could set the other server up as a linked server in your SQL Server. You could then run queries that compare the different entities in each database.

Unfortunately it is not. The 2 databases can be either MS SQL, Oracle, or "Anywhere" databases. I was thinking of querying both DBs to get data and store this information in either DataTables or what-not. Then somehow compare and output it all in a nice fashion.
The problem is in comparing and outputting...  Not sure if there is a slick way to do this, as I am sure someone else has done this before of comparing data between two DBs.

You could consider using LINQ to perform Intersect and Except set operations between entities that hold data from each data source. See this article[^] for more information.

hi every one
i want to develop a desktop application in hindi language can ny one help me how to achieve this
thanks for ur reply in advance
|
|

The first step is to determine whether your target Operating System versions have Hindi support. The second step is probably to decide whether you just want Hindi output, i.e. Hindi text on the screen or do you want Hindi input, the user enters Hindi text into the application, as well. The second requires more technology than the first. Then you'll probably want to read up on some of the technologies and standard you'll need. Assuming you're using only up to date desktop Windows i.e. XP or Vista you'll probably want to take a look at UNICODE www.unicode.org and then at Microsoft's documentation for UNICODE support in the Win32 API, like DrawText, and possibly at the TSF (Text Services Framework) and at IMEs (Input Method Editors) if you want Hindi input capability.
Once you've got a handle on all this then you can do your design. Just be glad you aren't working on WinCE and trying to deal with 16 languages including Chinese and Korean. 
Nothing is exactly what it seems but everything with seems can be unpicked.

This is an ASP.NET question. You did the right thing when you asked the question there, please don't cross post.

Hi people,
Does anyone know how to transfer files from one computer to another (not on the same network). I understand that in VB.NET you have the FTP libraries incorporated in the back end, but I'm not entirely sure on how to use them. I've tried this but it doesn't work, yet!
Dim uri As New Uri("file://C:\Documents and Settings\mhomsey\My Documents\Visual Studio 2005\Projects\CareerOneUploader\CareerOneUploader\bin\Debug\GENERATED_XML\Careersmehrmyc20080207.xml")
Dim reader As TextReader = File.OpenText(xmlFileName)
Dim xml As String = reader.ReadToEnd()
If (uri.Scheme = uri.UriSchemeFile) Then
Dim request As FileWebRequest = FileWebRequest.Create(uri)
Dim response As FileWebRequest = request.GetResponse()
Dim reader As New StreamReader(response.GetResponse())
Dim tmp As String = reader.ReadToEnd()
response.close()
End If
The code isn't finished but I just want to be able to send a file from this computer, to another remote computer. Does anyone have the same code?
Thanks very much in advance and I appreciate your help.

Well, to send a file via FTP, an FTP server needs to be set up somewhere.

What do you want exactly ? A program to set the volume on your computer ?

vb.net /framework 1.1
i am printing a string in printpage-event like this:
e.graphics.drawstring(mystring, myfont, mybrush, myrectangleF, new stringformat()) most times the string is so long that it doesn't fit into myrectangleF. how can i find out how many characters of mystring have been already printed into this rectangleF?
|
|
|
|

I think the only way to do this, is using a monospace font
like for instance 'Courier New'. Here every character uses
the same pixel width & height, so that you can predict your
Rectangle using the stringlength.
But probably you don't want to use a monospace font?
|
|
|
|
|
no, i don't want to use monospace font.
|
|
|
|
|
What you need to do is use the Graphics object method: MeasureString() to know what the width/height is of your text.
You can specify the maximum width you want the text to extend to and the method will adjust the height accordingly.
Hope it helps!
Richard
may your code be error free.

thanks richard. but i think i can't solve my problem like this.
sure, i could easily find out the height of my complete text ( i alreday did that), bit i thinks that doesn't help.
let me explain, what i want to do:
in my app i need to print data:
name & address & some other information (no problem so far)
some description (which varies in length between nothing at all to some pages (taken from a memo-column in my underlying database)
for drawing this description i use the space (as rectangleF), that is left on the page after printing the other stuff like name/address/and so on.
but if the description is longer than the space still available, i have to find out which part of the description did already fit on the page, and what part of that string is left to print on the following page/pages.
i can't figure out a possibility to come to a result with graphics.measurestring. maybe i need to strip down the text line by line, but i tried this earlier and didn't like it at all.

I see what your getting at now. I did some digging and found that an overload on MeasureString() will output the characters fitted, which should be just what you need!
I've create an example on how to use this feature. Originally I was going to write all of the code in a button handler but it got a little messy. I ended up writing a light wieght class called "StringGenerator" that you can customize. To try this sample, perform the following steps:
1. Create a new class called "StringGenerator" and insert the code below marked: // <<<< StringGenerator Code >>>>>>
1. create a blank form and set it to be the startup form
2. add a button with it's position set to: x=5,y=5
3. double click on the button to generate an event handler.
4. Insert the code snippet below:
'begin code snippet
Dim g As Graphics = Me.CreateGraphics()
Dim sf As StringFormat = New StringFormat()
Dim intY As Integer = 20
Dim originalText As String = "This is very boring text but I don't look at what the text says, I just look at what results the text will bring."
Dim stringG As New MyClasses.StringGenerator( _
originalText, g, Me.Font, New RectangleF(80, intY, 60, 50), sf)
stringG.DrawCurrentString()
While (stringG.HasMoreCharsToDraw)
intY += 60 'in this sample, 60 creates a 10 px padding
stringG.SetNewBounds(New RectangleF(80, intY, 60, 50))
stringG.DrawCurrentString()
End While
'cleanup
g.Dispose()
sf.Dispose()
'End code snippet
Note:This code is still very primitive but it will definitely get you started. If you step through the code, you won't see any output. Remove all the breakpoints to see the dynamically generated graphics. Let me know how it turns out!
' <<<< StringGenerator Code >>>>>>
'insert into -> EMPTY <- class file!

Public Class StringGenerator
Dim g As Graphics
Dim rectF As RectangleF

sorry that i come back with an answer that late. have been off for the last days.
thanks for the string generator code (and special thanks for converting it to vb.net - i just wanted to start to do it myself, when i spotted your message modification).
i integrated it to my printing routine, and it worked great. only very little modifications where necessary to make it suit to my needs.
thanks a lot.
