Int64 Not Working Above 2^53?
May 19, 2011In working with large prime numbers, I appear to have stumbled on a problem. Powers of 2 are showing up okay, but when I try to add or subtract from them, I get erroneous results. Below are the powers of 2, minus 1, for exponents 51 through 56. Notice that, starting with exponent 54, The resulting number is even, which is obviously incorrect. I used data types INT64 and UINT64 and got the same results for each.Here is my code and a partial list of the results:
Dim i, iTest
As UInt64

Converting Int64 To Dateticks
Dec 21, 2009Im reading data from a VB random file.
Using dim value as int64, the output is: 4674762526611734528 Using dim value2 as date, then converting to dateticks, the value is 627740064000000000 The actual date is: 26/03/1990
Why is the int64 value not the same as the dateticks value?? How do I convert the int64 value to dateticks value?

Option Infer - Detect Whether The Integer Should Be Int64 Or Int32?
Feb 3, 2011Will that detect whether the integer should be int64 or int32? What about if we run the program twice. Once we use small numbers and latter we'll use big numbers?
Let's look at this for example: vb.net Dim vector1 As List(Of Int64)Dim vector2 As List(Of Int64) vector1.Sort()vector2.Sort(Function(x As Int64, y As Int64) As Int64Return y - x
What about if I do: vb.net vector1.Sort()vector2.Sort(Function(x As Int64, y As Int64) As Int64Return y - x

View 2 RepliesPrivate Declare Function BlockInput Lib "user32" (ByVal FBlock As Long) As Long?
Dec 26, 2009In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor
Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:
FrmMain.BlockFrmMainInput()With these functions is the Main window:

It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.
How Long Can A Stopwatch Run
Jul 27, 2011I have a VB.NET app in which I'd like to use the Stopwatch class. The stopwatch will get reset every time it enters a particular method, which may be in less than a second, or not for hours. Is there a limit to how long you can let a stopwatch run before something bad happens? i.e. an error, or performance degradation?

Dec 23, 2011This is probably a really simple thing. Basically, the user clicks a button and a potentially long running task happens. I'd like to do a few things like toggle the button's enabled state, show a spinner, etc. In VB.NET Winforms I'd just do Application.DoEvents() and the updates would happen and the code can continue. How can I do this in ASP.NET? (preferable serverside or minimal javascript)
View 2 RepliesAsp.net Run Long Task Separately?
Dec 29, 2011I am developing a web application in asp.net vb. My current situation is,I have a main site say [URL] and another site for generating reports depending on certain user ids say [URL].If I click a button on [URL] I have to switch on the generate report page on [URL] and return to[URL]. [URL] should generate report and set a flag in database of [URL].Currently I am redirecting to the page in xyz.com and add the long running task to queue as follows and redirect back to [URL].
If ThreadPool.QueueUserWorkItem(New WaitCallback(AddressOf LongTimeTask), New Object) Then
Response.Redirect(returnURL)
End If
But the problem is its not dependable. Means some times the queue is executing correctly but some times not. There are no errors in long time task. Just the queue is not executing.
C# - Converting NAD83 UTM To Lat And Long
Feb 22, 2012Edit So the solution I posted from Jenner at VBforums was, obviously, in VB, and I used an online converter to port it to C#. Something was lost in translations, and that's why it was 10 miles off. I'm guessing I am just misunderstanding what the algorithms at the Proj.Net discussion boards are for and that's why they weren't doing what I wanted them to.

Handling Long Strings In VB?
Dec 21, 2011I develop in VB and often I'm writing long TSQL statements in SSMS but getting them into VB is a bit of a pain. I like SSMS during development because I can change the query / structure and test it when there are problems. Some of them become stored procedures and some of them I just keep in the code.I like keeping them in the code because when I have a problem with something, I can GREP my projects directory and find the code that does something (that I've forgotten) or someone asks something about how something works, I can look it up. I've yet to find a GREP for stored procedures. Is there such a thing?I've read in a "best practices" white paper how we're not supposed to concatenate super long strings with & _ but a hundred line proceure is a pain to nest in
sb.AppendLine(" WHERE [q3] IS NULL "
sb.AppendLine(" AND [q4] > 2
"
[code]....
C# handles these things much better than VB. I'm wondering how I can keep my code together during development and searchable later. I had my hopes up when VS 2010 offered implicit line continuation, that this would help my multi line SQL procedures. Again, I was mistaken. Perhaps I could write it all on one line. I'd be interested in knowing if there's a feature that I am not aware of. Well there are certainly many features which I'm not aware of, but I was referring to "long strings".
How Long Should It Take To Generate A RSA Keypair
May 8, 2012I'm using Bouncy Castle (c#/vb.net version) and generating a 4096-byte RSA Keypair to use in my certificate with this routine:[code]The procedure works ok, however it takes a very long time, up to one minute (I'm on a 2.4ghz pentium DualCore).Since I don't have much experience (almost none really) with RSA and all these things, I just wanted to ask if it's normal that it takes so long to generate the key, or if I'm doing something wrong.

View 2 RepliesQuery Too Long In .NET 3.5 And SQL Compact 3.5?
Jul 26, 2009In Visual Basic 2008 Express with SQL Server Compact 3.5 and the Usual DataSet / TableAdapters, My Query is too long:Changing the names, it is a query like this:
SELECT Table1.*, Table3.*
FROM Table1
INNER JOIN Table2
ON Table1.ID = Table2.T1ID
[code].....
Problem is, Table1 and Table3 have around 10 and 5 columns each, with rather descriptive names, and The Table adapter is insistent on writing all the columns out and therefore hacks off my command. (It won't take * 's, it always says it can't find the column Table1.* )
Is there a way around this?
