I came up with this solution:

Private Shared Function NeedNewFile(ByVal fileName As String) As Boolean
        Dim filePath As String = sPathToUse & "\Errors\" & fileName
        If File.Exists(filePath) Then
            Dim fInfo As New FileInfo(filePath)
            Dim fileSize As Long = fInfo.Length
            With fInfo
                If .Length >= (MAX_ERRORLOG_SIZE * 1024 * 1024) Then
                    File.Copy(filePath, filePath & "_Archive_" & Now.Day & Now.Month.ToString("MMM") & Now.Year & ".txt")
                    Dim sWriter As New StreamWriter(filePath, False)
                    sWriter.WriteLine("--New Log Created --//\\ " & Now())
                    sWriter.Close()
                    Return True
                Else
                    Return False
                End If
            End With
        End If
    End Function

Ad this seems to do what I need it to do (so far), now I need to do some more testing, make the target path larger than 10MB and see what happens.

Why are you anticipating this many errors during the lifetime of the app?

I have absolutely no idea about what the requirements of your project are but that doesn't sound quite right to me.

Dave,

I'm really not anticipating that many errors from the parts that I'm responsible for, but I work with a relatively new and young programmer who has a hard time (it seems) to do adequate exception handling. Realistically there may never be more than a couple error logs over the lifespan of the application, but I have a hard time allowing myself to assume something wont happen, I have to code for exceptions to the rules as well because you never know what the users going to do, thats just the way I am.

I have thought about this, but I know it will cost me my job (if I knew I could get away with it I would probably do it :->. Once, he actually "bitched" at me for putting code in a Try....Catch block, saying that an error couldn't possibly happen in that function and that I needed to remove it, to which I replied "Assumptions are the mother of all f**k ups".

He has a bad habit of assuming something cant happen, or that the user cant possibly do something to raise an error. No matter how hard I've tried to explain this he just wont listen, but hey in the past 4 months he's had over 20 "trouble tickets" for the processes he's coded, and I've had 2. Maybe someday he'll grow out of his arrogance and start seeing things in the right light Unsure | :~

I remember a guy on a development team I was part of yelling that at one of the sales guys who demanded a feature that we later discovered no one wanted. The sales guy just assumed that a potential customer wanted a certain feature. He didn't. And he didn't buy either.

Is he assuming he won't get fired for his "quality" code? That's the mother of all f-ups. Big Grin | :-D

Dave,

Thats exactly what he's assuming. He's been there coming up on 4 years, and we were both made part of the IT department about 4 months ago, we were just the personal programmers for one department, we didn't have to follow any of the SOCKS(sp?) Compliance issues, none of the Software Development Life Cycle or anything, if they wanted something we made it then gave it to them, so up until now no one ever knew of any "bugs" he wrote. I'm hoping that now that they're coming to light something will be done about it.

Dim i as Integer
dim Total as Decimal = 0
For i = 0 to lstTest.Items.Count - 1
Total += Ctype(lstTest.GetItemText(lstTest.Items(i)),Decimal)
Next
txtTest.Text = CStr(Total)

Converting it to C# is very simpel Wink | ;)

suppose the following:
dim str as string = "****abc***xyz***"
dim str2 as string = str.trim()
'str="abc***xyz" , where each star is a space
'its cut the spaces from the two sides

hi,

dim test as string = "   test  "<br />
textbox1.text=test 'will give you "   test  "<br />
textbox1.text=test.trim() 'will give you "test"<br />
textbox1.text=test.trimStart()'will give you "test  "<br />
textbox1.text=test.trimend()'will give you "   test"

basically, it will remove the white spaces from the string.

hope this helps

hello frnds,
trim() is basically to remove the spaces from left and right side of the string

let take an example
txtPfr.text = "****prasad****"
trim(txtPfr.text)

then it removes the sapce from both side
likewise u can use Ltrim() and Rtrim() methods too.
to remove Left and Right side sapces respectivelly.

best luck

hi,
provide the format in the tostring() function. try this:

yourLabel.Text = yourDateTimeObject.ToString("mm/dd/yy")'or ("dd/mm/yy") or whaterver acceptable format.

hope this helps

thank you ..
but i have no problem with displaying format, the problem is how to save the date in different formats.

check this

where exactly do you want to save it?

you could use the various properties like day, month, year ... provided by the datatime object to create a string that you like and save it to ....

the best way depends upon where you want to store the data.
you have not made it clear where you want to save it? i asked you in earlier post.

if you are saving the data in a database then you will have to store the datetime object, but if you are storing it in a text file, you can't do that.
you will have to format it. for example save the year,month,day... in a file and use it when you want to create a datetime object: datetime dt = new datetime(year,month,day) or you can save the ticks and use it to create the object when you read from the file like: datetime dt = new datetime(ticks)

hope this helps.
