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!

how to load data (Book) to text box when user just enter the book code?how to load data (student) to text box when user just enter the student id?how to write the code when user click the save button , the book quantity(Book) will reduce 1 and the all the data in textbox will save in database(Issue)the interface is like
[URL]
the database is show at
[URL]
the code is
Public Class frmIssue Dim dt As New DataTable() Dim rowIndex As Integer = 0 Dim rowIndex1 As Integer = 0
I'm using the book titled "Database Programming with Visual Basic .NET and ADO.NET: Tips, Tutorials, and Code".
I'm going through the chapter that has me do data binding by setting the properties of a DataGrid and TextBoxes.
It had me drag a DataAdapter onto the form and had me generate a DataSet. This part works fine. It also had me set the binding through the Text propert of each TextBox. This also works fine as it displays the correct data as the user navigates through the DataGrid.
I think there may be something missing from the code samples in the book because saving the data back to the database is not working and even no errors are reported.[code]...
I have been looking for a good Example of Code to Compare 2 worksheets in the Same work book I have not had much luck. The Goal when complete is to compare Sheet 1 to Sheet 2 Then the Difference Recorded on Sheet 3 as a complete row with a date Stamp in A . If it is just a change then it is color coated Orange. If total new entry that was not on the sheet then it would be green If a Row is deleted in would be Pink.
I programmed in Basic, Fortran and PL1 many years ago. I now am developing a complex Excel application that needs use of VB macros. I've recorded and modified several VB macros so far, but have gone beyond my skill level trying to use VB indexed variables that link back to a spreadsheet. What text/reference book would you recommend for my level of skill? I'm not trying to become an expert -- just need help with approaches and correct syntax to simple programming issues if, while, indirectly addressed variables, etc.
I'm trying to find a way to have text that would be "Live" as in if a user types an incorrect phrase/letter in a text box, a message will appear prior to a "save" button being pressed. It's pretty much the same as when you're registering on these forums, it checks the availabilty of the username as you type it.
I have a asp.net mvc route that is taking a url and doing a simple get and return the status code from the request.
<AcceptVerbs(HttpVerbs.Post)> _ Public Function ValidateUrlStatusCode(ByVal url As String) As ActionResult Dim code As Integer = 0
[Code]....
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.
i just want to make a program with first form to enter the serial if correct just continue to form2 if incorrect just a popup say like "Serial Incorrect" how i can make it ?
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
I have a batch file. It includes two lines, as follows: pkgmgr /n:unattend.xml pause I have run this batch file manually and it works (installs IIS on the local machine). But when I try to run it in code I get an error: "An attempt was made to load a program with an incorrect format". Here is my code to run the batch file:
When I run this function I receive the error "Incorrect syntax near ','. When I click OK, the data is transferred to the database with the event_date values all set to 01/01/00 00:00:00. Eventhough, it is 09/09/2009 and 19/03/2009

I had a weird series of errors involving e.Graphics.DrawString() when painting a panel.I am using a barcode font [Code 128] with a library that converts text to the proper format for Barcode readers.That's fine, however, when I draw it to the panel, that's where things stop being fine:But, here's where things get funky. When I put it into a TextBox instead of drawing it via Graphics.DrawString(), everything is peachy:In fact, the TextBox one looks much better than the Graphics.DrawString() one! Am I doing something wrong?[code]
I'm looking for a book that is pretty much A-Z for LINQ programming from Visual Basic. I am particularly interested in LINQ to SQL. I've found "Programming Microsoft LINQ in Microsoft .NET Framework 4" and while its description sounds interesting, there is no discussion on the book at all . Do any of you have any experience with this book? If so, what do you think of it?
I have been working on a project for some time now and I am stuck. I am trying to sense when a navigation software speaks so i can mute the volume of everything else on the computer.
my problem is that i cant properly sense the audio of the software. i am using windows 7 and vb.net. i have done a good amount of research, but i have not come up with an answer.
i am almost positive that i need to intercept the win32api call of the software to trigger the mute that i will use. i dont know how to do this, all the information i can find that is even close to this subject is for 98, nt and 2k.
does anyone know of any books (or websites) that contain information on this subject?
I just wonder that somone can give me propositions for some good books to learn VB.net / VB2008.. I know the basics.. So I think of not a book like for dummies.. Just something more a step forward for new things to learn.
i am searching a good book to learn ADO.NET 4.0,book should be excellent technical overview with practical examples,I want to learn ADO.NET Where should I start?
What I'm Not looking for:Now, just to be clear, i'm not looking for VB6 to C#.Net content, as i know there are a few of those out there.Also, I know about that "syntaxconversion table" website, where it compares VB.Net to C# language features in a side by side table. I am not interested in this either, already know about it.I'm also not looking for a converter, which converts C# code to VB.Net and visa versa, i know there are a few websites which do this and already have the addresses.Finally, I'm not looking for a C# book or resource that caters to current programmers, but specifically to VB.Net programmers!
What I Am looking for:To learn C# (VS2008 or preferably VS2010 version) given that i already know VB.Net 10.0 (VS2010)... as there are many things related to .NET that i won't have to learn again if i can find something that will leap me from vb.net to c#, many bits of the CLR, how .NET works etc... since the languages are the same in what they do, and what they use to do them, i don't want to have to re-learn all this again. The only difference is really the syntax, but also how the C# language differs in dealing with certain things, what default expectations/behaviours are in various scenarios etc...
The set of differences and similarities between C# and VB.Net are so unique that neither of these languages likely could share this unique set/combination of differences and similarities with any other language. So my point is, it really needs to be C# for VB Developers oriented, otherwise it'll almost cetainly be inappropriate or a re-hashing!
The problem is in the line that contains address.save(filename) the part address.save is underlined. When I backspace over the save, it gives me the options of what can go there and save isnt one of them. I am coping this out of a book.[code]...
May I expose my "small" problem?Here, i'm following a course in my University, called Introduction to Programming, there are only beginners in our class. i'm also a newbie, to say so.And some stupid students were not paying attention so he gave us a crazy assignment for Friday 30th.This is what his assignment consists in. I have created a PDF file from his requirements and some samples of Code.[url]
