I caused the VB.NET2008 IDE to do something extremely odd and unintentional with some code I was writing. As some of you know, I mostly write programs for industrial equipment. On one of our products, I needed to make certain forms automatically close after a timeout period. To do this, I began programming a usercontrol with a Timer on it (interval = 1000) and a ProgressBar. Timer.Enabled was set to the Enabled event so I could toggle it. When the control counted to it's timeout period, it would call Me.ParentForm.Close
So I build my project, and drop it on a form in the IDE and I see it begins counting! Huh... I had no idea timers were active in the IDE. I wonder what happens when it hit's it's trigger? I figure probably nothing since Me.ParentForm was actually the designer. When it triggered, the whole IDE crashes without save. I tried it twice now. Here's my

In the members region I declare _Name and assign it the value "NameA" but how do I assign this value conditionally?The idea is that if in some file there's a value set than that should be the default value and not the hard coded one, if non is set the hard coded one should stick.
#Region "Members"
Private _Name As String = "NameA"
#End Region
#Region "Properties"

I want to display an equation prior to solving it. Obviously in MS word etc I can use equation editor to write an equation, but I'm writing my own program.
Is there an easy way to display an equation. Obviously I could use text to write eg as text "a=b^2-3(c-d)/5" and everyone here would have little problem interpretting what I want but I want this to be accessible to 12 year old children.
Alternatively I could try and manipulate lots of text boxes one on top of the other to try and explain what I'm doing
The third alternative I thought of was to write in equation editor export the graphic and then import a graphic.
I'm sure I must be trying to reinvent the wheel - which I believe is the one thing OE programming is supposed to avoid.

Been trying to figure out why my progress bars (one in the status bar when the main window is open and the other in a window by itself before the main window is shown) go up most of the way, then stop till the processing is done.I have refresh in there where the action takes place, and that made it work mostely.Basically I'm loading a file into a string, then while in a loop, I'm processing the file by lines. I have a function that retrieves a line, then it does a:
pbProgress.Value = pbProgress.Maximum - sWork.length
pbProgress.ProgressBar.Refresh()
StatusBar1.Refresh()

I'm trying to convert code from Delphi to .Net. I'm stuck on one line:
//Delphi code ss := Copy(ss, Length(ss), 1) + Copy(ss, 1,Length(ss) - 1); 'vb.net code ss = ss.Substring(0, ss.Length - 1) + ss.Substring(1, ss.Length - 1)
Delphi combines the two substrings, while .Net just concatenate them like a copy.

I would like to develop a structure to maintain my user's text input somehow on each form to allow user to return to the form and see the prior input for potential editing. My app has four forms which accept user input and form a string for output to printer. In the eventuality that the user notes a mistake in the input after leaving the app, I would like to develop a structure to "save" the user input at the form level and allow for repopulating the text boxes with the prior user input. Make sense? I have no idea how accomplish that functionality. Maybe it's too complex for my purposes. What do the pros think?

I have a sql stored procedure that runs for about 3 minutes, I am looking to execute this stored procedure from asp.net, but I know that if I do, that asp.net will most likely time out. I'm thinking of just creating a job within sql to have it execute that stored procedure, and have asp.net call a stored procedure to call that job. I have a table that is updated when the stored procedure starts, and when it ends.
My application will use this to determine when the script has finished, however, I wanted to know if there is another way to run the stored procedure and not have it wait for it to finish to push a response back. I just want to know if there is a more efficient way to do this, or if I should just stick to creating jobs for scripts that take forever to run.

The file operation calls are returning before they are actually complete, or the disk is being cached somehow. What is happening here is that a zipped file containing a number of files to be updated on the users machine has been unzipped and the filenames are returned in an array called 'newfiles'. Each actual file unzipped is temporarily preceded by a '~' character. We rename each existing file to <filename>.old, then delete all the old files. However, sometimes when the code runs, the old files are not deleted. The only explanation for this I can think of is that the second 'Fileexists' is not seeing the files because the filesystem has not caught up at that point. I've never seen this behaviour documented anywhere, though. It works fine when single-stepped.
For Each fn As String In newfiles
If .FileExists(fn) Then
'rename existing file to .old
delpath = Path.ChangeExtension(fn, "old")
.RenameFile(fn, delpath)
End If
'rename the new file to correct name i.e. remove "~"

I am reading the article at: [URL].. Forms Authentication in ASP.NET 2.0". I am using VS 2008 and .Net Framework 3.5. I don't know if this makes a difference, so please let me know.
A user logs on to our system in the morning Based on their Windows Authentication, they can access several intranet applications. For a particular application, the user has to select their Organization or Position or Location.
Based on the user's Windows Authentication, once the user selects one of the three above and clicks a "Submit" button, a second page is launched that shows certain information about the selection based on the User's authentication.
For example, if User selects Organization, the following information will be returned based on the Organization THEY are a member of. They can not access information from OTHER organizations, ONLY their own based on their login credentials. This information returned as a result of the dropdownlist selected value includes: street address, city, state, zipcode, Bus. Unit #, etc. appears in labels on the second page.
The labels can be dynamically created at runtime. (I dont know if a User control can be created to do this, since the "Position" and "Location" will contain the same address information, and it doesn't matter at the moment). I just want to populate the labels on the second page (or on Postback) based on the User's log in credentials after they click the "Submit" button. Or, if they don't have to click a button, just have the information complete based on the selected value of the dropdownlist control.
