in VB6 the event is Form_Unload but it looks like you don't have a running form. If that's the case you have to check your messaging queue for the WM_CLOSE and WM_QUIT

For num = 0 To 7
For i = 0 To numSamps - 1
calSignals(num)(i) = data(i + num * numSamps)
Next i
Next num
where
I dim data() as double
redim data(0 to numsamps -1)
and
dim calSignals () as double
redim calSignals(0 to 7)(0 to numSamps - 1)
Indicates that the = sign is the problem. Can I not do this in VB?
thanks,
sb

You can't do this:
calSignals(num)(i)
In VB, it has to look like this:
calSignals(num, i) = data(i + num * numSamps)
The same goes for your ReDim statement:
ReDim calSignals(0 To 7, 0 To numSamps - 1)
Next time, copy and paste your code into the post. Don't retype it yourself.

I would like to create a external text file or .inf file to hold the list for a combobox.
Any help or direction would be great.

You might want to check out the FileStream[^] class. There's plenty of examples.

Thanks for the directions I did this
Imports system
imports system.io
then in the form load
Try
' Create an instance of StreamReader to read from a file.
Dim sr As StreamReader = New StreamReader("MyFile.txt")
Dim line1 As String
' Read and display the lines from the file until the end
' of the file is reached.
Do
line1 = sr.ReadLine()
ComboBox3.Items.Add(line1)
Loop Until line1 Is Nothing
ComboBox3.Items.Add(sr)
sr.Close()
Catch Er As Exception
' Let the user know what went wrong.
Console.WriteLine("The file could not be read:")
Console.WriteLine(Er.Message)
End Try

Hi all,

You can't use the stock ProgressBar for this. You'll have to "roll your own" to provide this functionality.
You can find such an example here[^].

I need a user to provide the date and time. I'm doing this by using two datepicker controls, one to set date and the other one to set time.
But the irritating thing is that I can't combine the two results!?
All Date and Time properties of a DateTime class are ReadOnly  (for whatever the reason), but it would be nice if I could just say:
UserDate.Date=pickDate.Date
UserDate.Hour=pickTime.Hour
UserDate.Minute=pickTime.Minute
Can anyone help me how to solve this problem?
Thank you,
Veljko

I solved it in the past this way:
Dim dtD as DateTime = dtpDate.Value
Dim dtT as DateTime = dtpTime.Value
Dim dtC as DateTime = dtD.AdTicks(dtT.Ticks)
I'm not 100% sure about the code since I go by heart, but I'm 100% sure about the method used.

This isn't going to work Briga. Even though the user is only entering time into the "dtpTime" DateTimePicker, this object still internally stores a month/day/year and is included in the returned ticks. So, adding the ticks of both the time and date DateTimePickers will push the resulting DateTime beyond the year 4000. Unless of course you are initializing dtpTime to the beginning of time.
See my post below for a better solution.

Yeah I believe you as I said I was going by heart. It did work something similar (the idea is by adding the two components).
Anyway your solution seems more elegant and efficient than mine.

The DateTime type is a Structure. Structures are value types which are typically immutable in the .NET framework, like the String type. The properties of an immutable types cannot be changed. Instead, the immutable object must be overwritten.
Why are they like this? Because Structures are passed by value (a copy of the original Structure). So, changing the properties of a returned structure would only change the copy and not the original.
Regarding your DateTimePicker handling, you need to overwrite your UserDate variable. Try something like this...
UserDate = New DateTime(pickDate.Value.Year, pickDate.Value.Month, pickDate.Value.Day, _
pickTime.Value.Hour, pickTime.Value.Minute, pickTime.Value.Second)

u may need to ad a merge module
Mapping.msm: This merge module is used to install the files required to support displaying geographic maps inside reports. This merge module is only required if geographic mapping is included in your reports.
