Check A Value And Make Sure That It Is Not A Negative Number?

View 3 RepliesWhy Does A Negative SByte Number Have 16 Bits
Jul 11, 2011I asked a question earlier about comparing numbers using the "And" comparison operator in If Statements and now I have been toying around with getting my head wrapped around bitwise operators. So I have written a very basic code that will allow me to see the conversion of any decimal number in binary format.[code]Notice here that I am using SByte as the paramerter - which should only contain 8 bits right? However, the message box that appears has 16 bits assigned to negative numbers.

VS 2008 - Windows 7 API - Number Isn't Even Negative Anymore
Jul 11, 2010My problem is with the following API.
Private Declare Function GetKeyState Lib "user32" (ByVal keyCode As Integer) As Integer In Windows XP, I could simply use the API like this: If GetKeyState(Keys.Left) < 0 Then 'Move Left If the key was pressed, it was a certain number below 0, the number itself alternated each time you pressed the key but it was always below 0.
My problem is that in Windows 7, when you press the Left key, the number isn't the same, in fact the number isn't even negative anymore. This problem tricked me at first into thinking the API didn't even work as when I ran the .exe of course my code did nothing since GetKeyState never returned a number below 0. I tested the value itself though and found that it never goes negative, the number for the key just decreases a little.
The weird thing is, while the .exe from the Debug folder proved my point that the GetKeyState number was different and thus the program didn't work, running the .exe from the Release folder actually worked, the controls were fine and the API returned numbers less than 0 for GetKeyState. But the .exe from the release folder was built with my old XP computer, as soon as I made a new build with my windows 7 computer the API stopped working again.
Why did Windows 7 change the number returned for when the key is down, is there a way to change it back without having to include some large package with my program? Why did the build from my XP computer work at first? Also it was only the one from the release folder, not the debug one, even though they were both from the XP computer.
I tested some more on windows 7 and found that every time I run the program, the number returned by GetKeyState is completely different. When the key is down the number is 1,000,000 units higher than up, but other than that the number is random each program start.
Mysql DB In Windows Form Id Field Has Negative Number
Jun 18, 2012I got a Mysql sql database for my project. The id field is set as auto increment, which seems to function correctly. But on the form in my text field and datagrid i see a negative number, while in the database its a postitive number. I do not really plan to use the id field right now, but when i do it might cause some problems.
Anybody know why it would show as a negative number on the form(textbox/gridview) and as a positive in the actual database?

Get The Revision Number To Change?
Oct 10, 2007I just want to know if the following behavior is by design. I start Visual Studio and open my VB project and rebuild it. The assembly version is set to 1.0.*. I get a version number of 1.0.2839.26817. Now as long as I keep visual studio open every time I rebuild, I get the same build and revision number. I have to close and reopen visual studio to get the revision number to change. Again I just want to know if this is by design since everything I have read says that the revision number is either supposed to be random or the number of seconds since midnight. Is there a way around this?

View 5 RepliesDoes An Image Hash Number Change
Mar 31, 2010I saved an images hash number to a database so that when my application pulls in images, I can compare this hash number to the hash numbers of the images comming in. The purpose is that if one of the images comming in has the same hash number, I can flag it. It seems that the saved hash number for an image is not the same for the exactly the same image when it has come in. Is this because the hash number for an image can change depending on the pc where its being created?

View 6 RepliesAny Formula To Change Latitude And Longitude Into Single Number?
Nov 27, 2011If there is a formula to change a latitude and longitude into a single number? I plan to use this for a database table in software that provides routing for deliveries. The table row would have that number as well as the postal address. The database table would be sorted in ascending numeric order so the software can figure out which address the truck would need to go to first, second etc.
For example I would use the following numbers for the latitude and longitude:
Lat = 40.71412890
Long = -73.96140740
Additional Information: I'm developing an Android app using Basic4Android. Basic4Android uses a VB or VB.Net syntax with SQLite as the database. Part of this app will have route planning. I want to use this number as the first column in an SQLite table and the other columns will be for the address. If I do a query within the app that sorts the rows in numerical ascending order, I will be able to figure out which postal address are closest to each other so it will take less time for me to go from house to house.
For example, if the numbers were:
194580, 199300, 178221
I can go to postal address 178221 then to 194580 and finally to 199300 and I won't need to take the long way around town to do my deliveries after they were sorted. As an alternative, I would be happy if there was an easy way to call a web service that returns maybe a json response that has the single number if I send a postal address to the web site. Basic4Android does have http services that can send requests to a web site.

View 6 RepliesAsp.net - Dynamically Change The Number Of Header Cells In Listview LayoutTemplate
Aug 11, 2011I'm trying to dynamically create a listview. on reports.aspx user selects a bunch of checkboxes. On the next page, user sees reports.aspx, and should see a table with columns of the checkboxes he selected. My idea was to create a listview, then dynamically change the header row of the LayoutTemplate, then change the select statement depending on which columns selected. This is what I have:
<asp:ListView runat="server" ID="ReportListView" DataSourceID="ReportListViewSDS">
<LayoutTemplate runat="server">
<table runat="server">
[Code]....
Problem is that this doesn't work because i can't put a code block (<%%>) inside the LayoutTemplate. Is there a way in the code behind to edit the LayoutTemplate, or another way to cycle through the Request.Form vars and build the table header row with it?
