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.

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..

You say you have "a similar piece of code in Java." Does that mean that you have a working program that actually accesses your bank accounts and does what you want?
|
|
|
|

Well, yes. it is working piece of code(a bunch of classes) but going obsolete and needs to be updated. one of my friends coded it, did not continue to complete the backend decision making mechanism to decide when to buy/sell, what to buy/sell.
basically, it submits login, pass, pin number and makes a connection.
I dont know if the bank would provide me with an API to simplify my task, but i would like to know if anyone with background both in finance and programming ever tried to program such a code, any comment would be appreciated.

This seems to be a popular question lately.
If it is hidden, it is not drawn at all. There is no "hidden grphics buffer" to BitBlt from. Therefore, there is nothing to capture.

i have a png file which includes 20 different icon. i load it into a image variable but i have no idea how i can cut icons from there.
Example Code
Dim img As Image
img = img.FromFile("Icons.png")
'i need an method like Getimage (x, y, Width, Height) as image
dim newImg as Image
newImg =img.GetImage(x, y, Width, Height)
Any Idea? thanks.
|

Your GetImage function could look like the following:
Public Function Getimage(ByVal sourceImage As Image, ByVal x As Integer, ByVal y As Integer, ByVal width As Integer, ByVal height As Integer) As Image
Dim result As Bitmap = New Bitmap(width, height)
Dim g As Graphics
Try
g = Graphics.FromImage(result)
g.DrawImageUnscaled(sourceImage, -x, -y)
Finally
If Not g Is Nothing Then
g.Dispose()
End If
End Try
Return result
End Function
Havent tested the code but I think it should work. In general it just generates an empty Bitmap, creates a Graphics object and draws the original image at a location so that only the needed part is drawn.
There are probably more efficient ways out there, but it should do fine this way for smaller images.

is there a way to have atleast 2 deferent colors of text in one textbox?
this is for a chat server/client project and I want deferent colors for messages coming from the server ect...
thanks for the help

use RichTextBox and its SelectionColor property.
|
|
|
|

The TextBox doesn't support this. You'd have to come up with your own version of a Textbox control to do this. Or, like the other poster said, use RichTextBox instead. It supports the functionality you're looking for.

this is what i came up with but it doesent work
<br />
Friend Sub DisplayText(ByVal text As String)<br />
Try<br />
<br />
frmB.txtpbchat.SelectionColor = System.Drawing.Color.Navy<br />
frmB.txtpbchat.Text = text & Environment.NewLine & frmB.txtpbchat.Text<br />
<br />
Catch ex As Exception<br />
MessageBox.Show(ex.ToString)<br />
<br />
End Try<br />
End Sub<br />

First, don't use string concatentation. Use the .AppendText() method of the RichTextBox. Second, position the insertion point to the end of the text before you call .AppendText(). If the insertion point is anywhere else in the text, the color won't be applied correctly.
This is an example:
RichTextBox1.SelectionStart = RichTextBox1.TextLength
RichTextBox1.SelectionColor = System.Drawing.Color.Blue
RichTextBox1.AppendText(text & Environment.NewLine & frmB.txtpbchat.Text)
