Now if I use firefox (using Firebug) and go to the url http://www.facebook.com/blah.html, I get the expected 404 returned. However if I use my application to call the mvc route via an ajax call, I get 200. If I set the request object's AllowAutoRedirect to false, I get 302. I never get a 404. I am verifying this once again through Firebug.
We are noticing this occurs BOTH in javascript and in VB.net 2.0. So basically both in server side and client side code. Basically if you run this equation 975328 - 153279.43 you get the following answer 822048.57000000007. However, if you run 975328 - 153279.4, 975328 - 153279.433, or 975328 - 153279.5 everything is returned correctly. WHY the system calcuates the 975328 - 153279.43 with an answer with 11 decimal places? Not to mention adding the 7 in the 11th decimal place, thus making the equation answer incorrect.Of course I know I can trim, set the answer to appropiate decimal places, etc., etc.the above is proven by just entering the equation into the immidiate window, thus ellimnating varibables such as object types, etc., etc.
View 3 RepliesIn my global.asax.vb I have a rule like so:
RouteTable.Routes.MapPageRoute("defaultRoute", "{*value}", "~/default.aspx")
So, if someone enters:[URL]...Even though that page doesn't exist, the application pulls up default.aspx
Now, if this wasn't using a wildcard it would be easy to pull this value in on default.aspx like so:
Dim prospect as String = Page.RouteData.Values("value")
But this doesn't seem to work with wildcards, e.g.:Dim prospect as String = Page.RouteData.Values("*value")
How can I get the page to pick up these variable values? e.g. one time might be janedoe, another johndoe, another goose, another 12345, etc. Whatever it is, I want it to be returned into the string prospect.

I have been having an issue with returning records from a SQLServer database where the date the record was created is between 2 user specified dates. When I populate the DataGridView with the results, they are incorrect and do not follow any recognisable pattern.
For example, if I specify the dates 05/05/2010 and 12/05/2010 I get the attached data in the DataGridView.
Code:
Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click

I want to use a database table as a a queue...but the processing of these messages cannot be done from the database.I have a table that stores the requests i get from a .Net component. I now have to read the data from these tables and make http calls to 2 webservices. Based on the response received from the webservices, the data gets archived or deleted.I had a few specific questions:
1. How do i make sure that if i pick a record for processing and the http call fails I should be able to go on to the next record, and then come back to this record at the end of the run
2. Is there an alternative to using the database as a queue(like MSMQ etc.), which option is better
3. I want to maintain an audit trail of the record status. Is creating a trigger to log the changes before the edit the best way to do it?
I have done the PING part, you click a button the it ping's the server IP Address, then return's the result via a label. I want to make one so it check's the HTTP status of the server and if it's on it display's a green circle with a label next to it saying HTTP Status is OK.

I'm a networking student and hardware is my forte, but am required to do this VB Programming class and this particular project is just about got me ready to pull my hair out!I inputted this code verbatem from the text entitled, "Programming w/Microsoft Visual Basic 2008" by Diane Zak have double & triple checked & this is exactly as is printed in the book on pages 471-473.But it comes up with errors, and then we're supposed to modify this thing so it will accept any word up to 10 letters and only allow letters A-Z to be entered by player 2.But if the original code doesn't work, makes it pretty hard to modify it & make it work!

View 12 RepliesFirst off, I am new to ASP.net, so this is new territory for me.I am using Telerik controls on a VB.net project. I get the following error as a javascript error for every action on the form. Changing any value, whether its a telerik slider, a radio button, asp:button, submit button, telerik rating. Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
I understand that the 500 error is an error thrown when the server doesn't have any more details, however I was hoping someone might have had a similar situation and can point me the right direction as I have a good feeling it has something to do with the Telerik controls.
I was able to submit the form using javascript however then I get the following error, and I don't know if they are related or not.Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

The following code in C# gives result "228452386"
UInt32 a;
int k = 0;
a = 0x9E3779B9;
a += (UInt32)(url[k + 0] + (url[k + 1] << 8) + (url[k + 2] << 16) + (url[k + 3] << 24));
After above code is ran, "a" contains "228452386" But the following same code in VB.Net results in "Arithmetic operation resulted in an overflow". Basically the last statement is returning value "1868983913" so the runtime error is generated.
Dim a As UInt32
Dim k As Integer = 0
a = &H9E3779B9UI
a += CUInt(AscW(url(k + 0)) + (AscW(url(k + 1)) << 8) + (AscW(url(k + 2)) << 16) + (AscW(url(k + 3)) << 24))
note the variable "url" in above code could be any string and it is same for both codes.
EDIT:When I run the following statements in both C# and VB.Net than they both return same value
C#
(UInt32)(url[k + 0] + (url[k + 1] << 8) + (url[k + 2] << 16) + (url[k + 3] << 24))
VB.Net
CUInt(AscW(url(k + 0)) + (AscW(url(k + 1)) << 8) + (AscW(url(k + 2)) << 16) + (AscW(url(k + 3)) << 24))
Both statements return value "1868983913" for "url" "info:microsoft.com". But when I run complete statement with a += ..then VB.Net gives error while C# returns value "228452386".
I have created a few months ago a simple tool in vb.net, that sends an xml code to server, and that server sends response after a while. Everything is performed in http session, for that purpose I use webbrowser control and webclient. I know it could have been solved in different way, however iam not an expert in vb.net, and also didnt want to spend too much time on it. Anyway it worked, until they had changed something on the server. Let me explain in a few words how that tool works, so it will be easier to understand the problem.
In the first part, I open an URL in the webbrowser control, subsequently I enter xml code in the textarea on that page and click on the submit button. In result of that I get another page with some data on it, namely links to xls files. In the next part I use webclient for downloading those files. What is important for all of these operations I need to use the same http session id.
So, simply by now, i just set headers in webclient - WebClient.Headers.Add("Cookie", WebBrowser1.Document.Cookie.ToString) What have guaranteed to use the same session id by the WebClient. However, after the change made on the server mentioned before, the JSESSIONID value is not available in that string. When I use https analyzer (fiddler), I can see that value there...until moment when I am using WebClient. Of course due to that fact, the webclient won't download files for me, because the session id is not the same.
There is one more thing, what would be useful. When I checked the cookies file on my harddrive, I saw that line starts like #HTTP_ONLY. I think that would cause that problem with jsessionid.
Now, I am coming to my question Do you have any idea, how I would get that JSESSIONID value ? It is sent from webbrowser control, however don't know how to get it.
I have a form which I use to read data from a text file and export it to an excel template file. The data it reads is constantly updated so I would like to add a check box to cause the data to be read every 10 seconds. It's set up so the user can either do one quick scan by clicking a button, or they can click the button while also having the check box checked and it will scan every 10 seconds.The problem is, once I check the check box, I can't uncheck it. I have created a greatly simplified version of my original code to demonstrate this concept.
