You can but VB.net likes you to specify that the splitter character is of type char. Also the single quote is the comment character in VB.Net so you have to use double quotes.
myString.split("-"c)(0) 'gets xxx
myString.split("-"c)(1) 'gets yyy
If you have knowledge, let others light their candles at it.

Sorry for writing this Question to this part, but i write it in SQL part, i got no answer
I have a table named "DebitsAndCredits" which has fallowing columns
AccountNumber char(12)
DebitCredit bit
Amount money
I have the same table in two databases which are MB0001 and MB0002
I would like to join them in a one result set.I write
SELECT DISTINCT (AccountNumber ) ,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =0 AND m.AccountNumber =f.AccountNumber ) as Credit,,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =1 AND m.AccountNumber =f.AccountNumber ) as Debit
FROM DebitsAndCredits Order BY AccountNumber
UNION
SELECT DISTINCT (AccountNumber ) ,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =0 AND m.AccountNumber =f.AccountNumber ) as Credit,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =1 AND m.AccountNumber =f.AccountNumber ) as Debit
FROM DebitsAndCredits Order BY AccountNumber
i dont know why it is not working in my way. I expect a table has three columns (AccountNumber,Credit,Debit ) as a result.
What is Wrong?What do u offer for me?

you must specify the database names in the query eg.
Select ..... from MB0001..DebitsAndCredits m1 ......
Union
Select ..... from MB0002..DebitsAndCredits m2 ......

Well, there's nothing we can tell you since you haven't provided any useful information about the component RTD is connecting to. Is this a component that you wrote or a third party? What does this component do? We would also need to know about any error messages that are thrown.

I have an application written in VB6 that allow others to write plugins in the form of an ActiveX control. Now I want to allow dotnet usercontrols as plugins as well.
There are examples on the net of how to expose a windows forms usercontrol to COM as an ActiveX control. Although not actually supported by the framework, these seem to work if the usercontrol is loaded in a VB6 form. However, when the dotnet usercontrol is loaded inside a VB6 usercontrol, arrow keys stop working. Apparently they are interpreted as tabs (even if focus is in a textbox or listbox).
Now my question is, first, is there a way to solve this? Any pointers would be appreciated.
Second, since this is not really supported and I already have seen problems, I'm getting worried about more problems ahead. Is there anyone who has used dotnet usercontrols in VB6? Does it work well, or are there other problems that will appear later?

Take a look in the System.Drawing namespace which contains classes for drawing anything you like on a form or usercontrol.

Good day to all,
I have a Access2000 database and would like to edit my entries from the internet. How could I go about setting the webpage and site up? How can I also provide security as I want to limit the access to my database to a number of users only. Thanks alot.

Well, first of all you need to write an ASP.NET site. I'd recommend using C#, because it sounds like you need a lot of help, and there are a lot more people answering C# questions, and C# samples, here on this site.

You can filter via IP, or set up a password system, whichever suits you better.

Hi Christian,
Thanks for the opinion, but my project is using Visual Basic and database is Access. My project dateline will be in a few wks time. Hence I dont think there will be time for me to merge from one programming platform to another.
I will stick to VB and Access. Any help from the rest?
Rgds,
James

Do you mean VB6, or VB.NET ? If VB6, you're screwed. If VB.NET, you can still use ASP.NET, but you'll find less help online, at least here.
Why do you have a project on for which you have 2 weeks, and not the faintest idea how to do it ?

First, since you mentioned "browser", your question really belongs in the ASP.NET Forum, not VB.NET.
Second, fix what? Be sure to include a code snippet in your post so we can see what's going on and how your doing things.

First time contributor
I have a copy application that copies a folder from one location to another.
If Directory.Exists(loc1orginal) Or Directory.Exists(loc1backup) _
Or Directory.Exists(loc2original) Or Directory.Exists(loc2backup) Then
Try
LogEvent("Copying " & loc1orginal & " to " & loc1backup & " ")
fso.CopyFolder(loc1orginal, loc1backup)
If chkLocation2.Checked = True Then
LogEvent("Copying " & loc2original & " to " & loc2backup & " ")
fso.CopyFolder(loc2original, loc2backup)
End If
Catch ex As Exception
LogEvent("Exception generatted: " & ex.Message)
berror = True
End Try
I would like to add a progress bar to the app for the user, simple! But how do I measure the values needed to feed the nim and max values to the progress bar comtrol? Will I need to compare size of the directories and match from there????
Please help

If your going to use the File System Object CopyFolder method, you really can't add a meaningfull progress bar since CopyFolder will not fire any events you can subscribe to to update your progress bar. A couple of alternatives would be to fire off the Copy process you find in Explorer, which has its own progress bar, or write your own Copy function that can track the number of files/bytes it needs to copy and update a progress bar itself. Using the code you have now, you can't add a progress bar to it.

Hello,
In VB6, MoveLast is an method of Adodb.Recordset. Can anybody tell me that what is the alternate function in VB.NET. Because in Vb.net, this function is not available.
Regards,

Hi Eshban,
there is no corresponding/alternate method in vb.net.
i'd suggest you read up on ado.net (overview, samples) a little (or alot). ado.net is a subset of the .net bcl that can be used to work with data and data structures.
hope this helps.

In ADO.NET objects are now treated as collections. To move to the last row in a dataset you can retrieve the .Rows.Count property, and then access the last row by index like a VB6 collection.
Just remember that unlike old VB6 collections, the ADO.NET collections are zero based , so you would access the last row by selection of
.Rows(.Rows.Count-1))

Dear all
I program in vb.net and use T-sql. I want to get into web development and i have heard about These development languages: vb.net , c#, c++/c.net , Asp/Asp.net , XML, XSLT, HTML , DHTML , T-sql , com , com +
and these platforms : Ms Sql 2000 , my sql, microsoft IIS
the picture that i have is very convoluted as to what i need to learn in order to be able to develop web sites that can be dynamically linked to a remote sql server.
Any help and advise that you can give me with regards to development capabilities that i need to learn to achieve this task would be greatly appreciated.
thanks

you'd be much better off posting your question to either the web development or asp.net forums. your question isn't really related to vb.net.

It is possible that you will need to learn all of them but you can focus on two or three and it all depends on what you are comfortable with. I suggest start to learn HTML then ASP.net and since you already know VB.net use this as your code behind language or more popular c# if you want to learn. Not really much to it since you already know how to code. You should also learn javascript for cleint side coding. Pick up an html and asp.net book and navigate the pages of CP.

Has anyone ever tried to code a piece of software to browse his bank(hsbc for instance) accounts, buy sell stock shares thru this software. This software is not meant to be only with ASP.NET, it can also be built using MFC or any other related libraries of .NET framework or previous Microsoft related libraries. I have got a similar piece of code in Java, however I would like to study its .NET version, what would it be like and what libraries of framework would be used, what methods be called to make a connection to the bank's server, browse accounts and buy and sell stock shares. I am trying to code a non-asp version of it for http://www.hsbc.com.tr/. Does anyone have any idea. I would later automatize my buying and selling thru some technical indicators..
Thank you for any opinions..
