Why is my beginning for each statement linking to the wrong ending next statement take a look at the code. The for each shipment is linking to the end next comp statement. My head is cracking open over this.
Dim getshipments = From s In mydb.ships _
Where s.ship_dte.Date <= month And s.ship_dte.Date >= month2 _
Group s By s.shipid, s.ord_num Into g = Group _

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

I am using Visual Basic 2010 and I am makeing a simple login app it prompts you for a username and password if it gets it right I want to open a form then close the previus one but when I do me.close it ends the program and I can't go on I am positive its working because I get the right password and username ut I can't close the first windows I tried to hide it but when I do I cant close it and the program goes on without quiting and with a hidden form I heard rumers that there is Sub that can control the x in the corner if there is one that would probably solve my problem but I can't find it heres the code for the login form

I'm writing a class library and I need to be able to shut down the main code in certain cases.
I know I could raise an event and listen for it in the form called by application.run but I would like to find a way around it.I wouldn't be opposed to try to throw an exception that if unhandled would close the application... but would prefer to come up with a more elegant soln.
I converted this app from VB6. I have 2 forms. Form1 instantiates Form2 via a Menu Item.I am having trouble getting Form2 to end when clicking close (X). If Form2 is 'idle' it closes fine; but if I am in a loop processing anything all the events fire, but it continues processing in Form2. I've tried messing with Dispose, Close, Application.Exit, Application.ExitThread. My last attempt was creating my own event to fire back to Form1 and dispose Form2 -- and it hits it but Form2 is still running. What is the deal? BTW if I use just Show vs ShowDialog -- Form2 just blinks and disappears.[code]

View 6 Repliesit was regarding in vb.net text operations, i want to replace the text by finding some particular text.but the problem arises when the starting and the at the end delimiter of the string is something same every-time but middle thing keeps on changing so how can i work out with that?? str = Replace(str, "abcdparameter = xyz123;", "abcdarameter = my defined parameter;")
i tried to learn some regular expressions but i am not able to get that.the xyz 123 is same every-time....and also there is one delimiter at the end of the parameter string so anyhow you can select the whole line and replace it.
I want to make a very small program where the user inputs a starting time and an ending time that is in "clock time (?)" and the program converts it to total minutes in one box and a decimal total in a second box. I have 4 textboxes, 2 are masked text boxes (military time) for input and two are not, for output and the math is coming out weird.
If I put a start time of 0925 and an end time of 1015, the results I'm expecting would be 50 total minutes and .83333 total as a decimal. I don't think I'm converting the textbox input correctly as I'm not getting anything near that. I am using a button to calculate and another to clear the boxes, just FYI. Also, I'm not sure what to do about any times that span the noon hour except to use an absolute value.
Public Function Time()
Dim StartTime As Double
Dim Endtime As Double
StartTime = txtStart.Text
Endtime = txtEnd.Text
txtDecimal.Text = (Endtime - StartTime) / 60
txtMinutes.Text = Endtime - StartTime
End Function

I have written a converting program, which converts binary files to ASCII files. (VB.net 2010). I need to have a functional "stop" button on the form and I was wondering if there was a simple command to make a program stop, exit all procedures, and wait for user input on the form.
It is not feasible to multithread this application, as it frequently interfaces with the form. Currently, I have a global boolean variable which becomes true if the stop button is pressed, and I have internal loops checking to see if the variable is true. However, I don't to waste CPU on checking a variable if it's not necessary.
If txtLog is a RichTextBox control:
Dim text = "hi" & vbCrLf
Debug.WriteLine("t:" & text.Length) ' --> 4, as expected
txtLog.Text = text
Debug.WriteLine("tL:" & txtLog.TextLength) ' --> 3. muh?! :(
Having looked at the RTF spec, the end of a paragraph is notated as par, which is neither CR nor LF. This makes sense since RTF is markup language; like in HTML, line endings have little meaning on their own.
So presumably, on writing into the RichTextBox, my line ending is being encoded into par. And then, on extraction, the par is being translated back to a real line ending for use.
It turns out that this line ending is vbLf.
Why, since Microsoft near-consistently employ CRLF for line endings, would RichTextBox translate par to vbLf instead of vbCrLf?

I have a class that's getting an XML document from a URL. I've verified that the XML from the URL has an newline at the end. For some reason, though, this newline is stripped off before being fed back to the user, which is causing an mal-formed XML error when the users feed this XML file into other programs.
Dim reader As XmlTextReader = Nothing
Dim filename As String = _partID & "_" & _majorRev & "_PreCheck.xml"
Dim localFile As String = fileDialog.FileName
