Am working on converting my VB6 mid() functions to .net .substring.I cannot figure out this part of it.Here's my VB6
txtInput.Text =Left(txtInput.Text, txtInput.SelStart) & strtext & Mid(txtInput.Text, txtInput.SelStart + 1)
My new .Net is like this:

I am working on a simple Point of Sale Program for my Intro to Visual Basic class. I am trying to pull a substring with a decimal point (ex 0009.50) from the string I get from my readline and turn it into a decimal value for calculating money values. Something is wrong with they way that I am converting and I can't find how to to it write in my book.
Private Sub addButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addButton.Click
Dim currentLine As String = String.Empty
[Code]....
How will I select a substring with 2 criteria? I have a Richtextbox where I select a number after a : with this code; For Each line As String In Richtextbox1.Lines Dim equalsPos As Integer = line.IndexOf(":") + 1 txtFound.AppendText(line.Substring(equalsPos, line.Length - equalsPos)) Next This is working ok, but the whole line.length is appended for number2. The line ex. Some text:my number some text-my number2. I want my number appended to txtFound, and my number2 appended to txtFound2. With my code only number2 can be appended correct.
View 4 RepliesI'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml
The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.
The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:

Im not too experienced with VB so this question will probably be fairly easy to answer. Im trying to take a 4 character value from a textbox and make sure it meets these specifications: 1st digit = and F OR P, 2nd and 3rd digit any A-Z value, and the 3rd Digit a 1 OR 2. Whats wrong with this?
part1ID = idTextBox.Text.Substring(0)
part2ID = idTextBox.Text.Substring(1, 2)
part3ID = idTextBox.Text.Substring(3)
If part1ID Like "[FP]" AndAlso part2ID Like "[A-Z]" _
AndAlso part3ID Like "[12]" Then
I am trying to remove VB6 type code and use VB.Net code, in particular, remove "Left" and use "Substring". This code does not do what the old style code does. It seams to ignore the first two chars and forces the msgbox prompt no matter what I type in the textbox (at "Leave").
Private Sub TextBox5_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox5.Leave
If TextBox5.Text = "" Then
'Do nothing

my goal is to
1.Take an file(exe,dll,etc)
2.Convert it into hex
3.place that hex values in a stack
4.Execute the values inside the stack to its original form(i.e. take the elements out of stack and then convert it to a compile format)
Imports System.IO
Sub Main()
Dim fileName As String = "ABC.exe"

I have what might be a dumb question, and/or discussed at length back in the 2005 days, but I could not find anything on it. Sometimes Google Fails me I am moving a old vb 6 application to .net and I hit a roadblock on ADODB. Now I used the converter to see what the effort was going to be and the first thing I noticed was that I could no longer bind my Text Data source like I used to.

I have visual studio 2010 Ultimate, but I cant convert a vb6 project easily. I just downloaded and installed the vb2008 express because I know it should have the capability to upgrade/convert it with reasonable accuracy.

We are currently running a 32-bit VB.NET 2005 application with a 32-bit SQL 2000 data store. The network guru is going to be upgrading the server and SQL to a 64-bit version on both. Will the 32-bit application still connect to the 64-bit data files? I am guessing I will somehow need to tie in the 64-bit drivers somehow, but will those work on a 32-bit development system?
View 4 RepliesI was converting my VB6 codes to VB 2008. There is a section i use a third party application (Microsoft Excel) to print report. But now VB 2008 is not accepting one of my statement. the statment is shown below in bold letters.
oSheet.range("H" & Row & ":" & "J" & Row).Value = Array(InvoiceNo, , Today)
it works in VB6 but fails in VB 2008 because of the Array statement, is there any replacement for this in VB 2008.
I have been converting my VB6 programmes to VB 2008. many of the problems that came up I have been able to solve; mostly by trial and error. However, I have one problem that was easy to handle in VB6, but I don�t see how to do it in VB 2008. I have checked Google, but didn�t find anything exactly similar to what I want to do.
On my form in VB6 I added two text boxes, each with it�s own name. I then copied these two and pasted them back onto the form, under the original textboxes, 5 times. Each time I was asked whether I was creating an array; I confirmed that I was.
I could then code as follows:
For x = 1 To 6
BidderName(x) = txtBidderName(x)
BidderCommunity(x) = txtBidderCommunity(x)
[Code]....
I tried to do the same thing on my VB 2008 form, but it does not ask whether I was creating an array, and in fact the array of textboxes on the form, is not an array!
how I get around this. The form has to show an array of textboxes, which are entered in order.

View 2 RepliesI'm having some trouble converting the format of a date in .NET 2008...
Dim currMonth As Date
currMonth = Format(Now, "mmm")
From this code, I need to extract today's date in the format of "mmm" (so it should return.. "Apr")This worked in vb6 but not in .Net, I keep getting some sort of conversion error.. I looked at using theformatdatetime option but it doesnt have the format that I need... only short date/long date...that kind of thing.
I have an application that was developed and is maintained in VB.NET 2003. Is it possible to convert the 2003 files to Visual Studio 2008 and maintain the program in 2008? If so is this fairly easy to do?
View 4 Repliesi have to get this off my chest.Forgive me... I'm a relative newbie stuck in the vb6 world because of my job.vb6 to vb .net is a huge change in the way one has to program (and to think). I never could figure out the big picture of things with .net.Everything is a class..? What's with all of this... Class this, Interface to a class, inheritance (of classes) here, casting? polymorphism.
As a newbie to vb.net (I use 2008)... I just wanted to say this out loud and see if i can even get my terms correct. Vb6 is a good language for beginners but not a real professional language and (vb6) is effectively a watered down, lazy man's (quick and dirty) way of creating programs to solve some particular task.

View 5 RepliesI have made an application with a client, server and listener. The server is a console app and the other two are Windows Forms Applications.
Basically i am using a Network Stream to send messages from the client which go through the network to the server which bounces them to the listener which then reads the message and tells the app what to do. (For example if i sent "shutdown", the listener would read it and then execute "shell(shutdown -s)".
The messages are sent like the following SendMessage("shutdown") but when i use a screen capturing API and send from the listener to the client like so SendMessage(background) i get the following error:
Quote:
Value of type 'System.Drawing.Bitmap' cannot be converted to 'String'.
This program, it reads in a file, and displays it in hexadecimal, like using a hex editor. It then goes to compare the strings and whatnot, and display certain values. During the program, there is a time where I need to display a set of offsets as decimal because that is the way that it is shown regularly.
Taking the two specific offsets and displaying them in hex ends up giving me something like "3039" or "000A", which should respectively convert to 12345 or 00010. This "ID" that I am converting, can be 00000 to 65535, which in hex is 0000 to FFFF. The current method I was given only works if the value is less than 512 or something like that.
