 | I don't have access to a system to verify this but two options come to mind. 1. get a list of all PIDs of processes named java.exe just prior to launching the new instance then use that list to determine the PID of the new process, then use that PID … |

 | Is the database on the same machine as the application? Is the dababase server on his machine named the same as on the machine used to develop the application? Does the connection string contain the correct information to connect to the database? Does the user have sufficient access rights to … |
| | If I understand, you want the size of the scroll bar to be proportional to the font size of the selected text. In a RichText control, the scroll bar (vertical) represents two things 1. the position of the visible text in the entire RichTextBox text 1. the "size" of the … |
| | I don't have access to VB while my computer is in the shop but let me make a suggestion (you'll have to verify the syntax). You can check all of the textboxes on the form by For Each tbx As TextBox In Me.Controls.OfType(Of TextBox)() If tbx.Text <> "" Then 'process … |
 | >Are you trying to get answers to your own questions? At first I was here to get answers to questions. As I got more comfortable with DaniWeb I started "putting back in" by answering questions. Now I'd guess I run about 99% answering and 1% asking. I'm not saying that … |
| | I wrote a sample code snippet that demonstrates how to use a [BackGroundWorker control](http://www.daniweb.com/software-development/vbnet/code/440614/backgroundworker-ip-monitor). Perhaps that can give you a start. My regular machine (with all the dev tools) is in the shop so that's the best I can do at the moment. |
| | I don't have my regular computer with VB at the moment to check this, but to move a picturebox (or any control) you modify the Location property by PictureBox1.Location = New Point(xvalue,yvalue) And you can check for collision by comparing the edge x value (left or right as appropriate) of … |
| | The confusion might be because of a misinterpretation. You use single quotes around a field value when the database field is of type String, not when the VB variable is of type String. For example, if the CompanyID field in the database is an int then two similar (but using … |
| | You could also use a dictionary as in Dim transform As Dictionary(Of String, String) and populate it where the key is the original char and the value is the replacement. Then you can do the replacement by For Each key as String In transform.Keys TextBox4.Replace(key,transform(key)) Next Caution - this will … |

| | Re: A Solve Bar? I like the new feature but I am concerned that this will lead to people posting "bump" and other such empty content just to get their names in the bar. |
| | A cleaner add would be For Each dRow In dt.Rows Dim item As New ListViewItem(dRow.Item(0).ToString) For i As Integer = 1 To 8 item.SubItems.Add(dRow.Item(i).ToString) Next ListView2.Items.Add(item) Next  |

 | Re: Your Pet Peeve A lot of grammar peeves such as **People who don't know how to use reflexive pronouns** "How are are you?" "I'm fine. Yourself?" It's called reflexive because it reflects back. You can say "I will do it myself" because "do" relects back on "me". You can't say "If you need … |
 | When I was still working stiff and had time to kill I'd write system integrity softwre (perform various checks and text the standby person if errors), rewrite old apps to improve them or I would learn some new technology, languge, etc.  |
| | Anyone who lists "Family Guy" as one of their favourite shows is someone who (I think) doesn't take themselves too seriously. In other words, my kind of people. Welcome aboard. |
 | I carried a cell phone for the last 10 years I worked. I spent far too much time on 24x7 standby and having my workday repeatedly interrupted with non-emergencies. When I retired in 2008 I swore I would never own another. So far so good. I relish my time without …  |
 | I hate songs with no originality and lots of repetition. Ever see the guest acts on American Idol? If it wasn't for the background dancers, fireworks, smoke/fog, background videos, etc (most of which give me a headache) who would listen to that crap. Sure, there are a few talented singers/composers/performers … |

| | What database system are you using? Autoincrement fields are a function of the database and are usually integer fields. The DBMS assigns the value automatically. If you want something other than integer then you can select the largest value, strip off the non-numeric part, add one then get the new …  |
 | Re: Table values If your table has the fields (for example) myBooks ISBN Title Copies Borrowed You can get a list of the number of available copies of all books by SELECT Title, Copies-Borrowed AS Available FROM myBooks If a book gets borrowed and you need to update the table you can do … |
| | I was thinking about installing Visual Studio 2012. Does anyone know if I can have both 2012 and VS 2010 installed at the same time without screwing up either or both?  |
| | The obvious guess would be either TextBox1 isn't defined or sqlDataset isn't defined. Put a breakpoint at the line where you get the error and try to examine both objects. |

| | I'm not up on data bound controls so I can't speak to that, but the query shouldn't have single quotes around numeric fields. Try "UPDATE Inventry SET QTY = QTY - " & qqttyy & " WHERE CODE = " & codee Also, you needed a space before "WHERE". If … |

 | To start with you can ping another node by My.Computer.Network.Ping(txtWeb.Text) where txtWeb.Text is an IP address or DNS address If you just want to do the occasional ping then that should suffice. If you want to use it to repeatedly monitor another address while you do other things then you … |
| | Re: txtcode Here is a sample of code that gets values using an OleDbConnection and a DataReader. AddRow just puts the three values into a new ListView Row Private Sub btnOleDB_Click(sender As System.Object, e As System.EventArgs) Handles btnOleDB.Click ListView1.Items.Clear() Dim con As New OleDbConnection("Provider=SQLNCLI10;Server=.\SQLEXPRESS;Database=PUBS;Trusted_Connection=Yes;Connect Timeout=15;") Dim cmd As New OleDbCommand cmd.Connection = … |

| | Re: labl What line is throwing the error? Why bother converting all of the control values to integers and dates when all you are doing is putting them back into a string? Don't put single quotes around values in the query when the corresponding database field is numeric. |
| | I presume that the user enters numbers in all three textboxes then clicks a button to perform some action. In the button_click handler you get the numeric values from all three textboxes then do a comparison and display an error message if the Obtained_Marks value is outside the range. First … |

| | I suggest you have a look at TrueCrypt. It is open source and free and I have used it for years. You can create an encrypted file of a user-specified size. Once the file has been created you mount it (via TrueCrypt) as a virtual drive then copy files to/from …  |
| | Try the following. I don't have a sample database in Access so I haven't tried this query. I used SQL with the COALESCE function (does the same thing as NZ), then did a copy/paste. "SELECT StudentID, NZ(Physics,0) + NZ(English,0) + NZ(Chemistry,0) + " & _ " NZ(Biology,0) + NZ(History,0) AS … |

| | I have no way of knowing where your code is being executed. Is any of the code inside the timer Tick event handlers? For what you are trying to do I would put the following code in the Timer2_Tick handler counter += 1 Label1.Text = counter If counter = 180 … |
| | It looks like you pretty much have it except for the Else (and you should use & instead of + to concatenate strings). If TextBox2.Text = ".\sys\clock" Then TextBox1.Text = TextBox1.Text & Environment.NewLine & "It's " & DateTime.Now Else Textbox1.text = "You didn't use the .SYS\ code" End If |
