I went ahead and made a fresh database and a fresh VB app to make this as easy as possible. I'm running what i believe to be the most up to date software, both 2008 express editions. I want to add a data source in VB to connect to my database in the Sql management studio. I click add connection data source = Micro. SQL Server compact 3.5 I navigate to the DB file Then I get an error "you do not have permission to open this file."
For me it seems like the an event hooking up on an another event?But I have tried everything to translate this into VB.NET code?I have found out that EventHandler management in VB.NET is far from as good it is in C# as many other things.
I have created a button its function to get the date and write it in a text box , and the month in anther text box while the year will be in four text box each digit will be in 1 text box
I am creating a password managment tool and for the storage I will be using a text file, I want to encrypt so I decided I will use the Rijndael cypher. I have found source code which does this to a file:
http:www.codeproje...ncryptFile.aspx. It is well explained but I am but still struggling to understand parts as I never looked at cryptography at all before.
Private Function CreateKey(ByVal strPassword As String) As Byte() 'Convert strPassword to an array and store in chrData. Dim chrData() As Char = strPassword.ToCharArray 'Use intLength to get strPassword size.
[Code]...
This assigns all of bytekey with half of the hash from byteresult. Am I correct? If not why not just use SHA256 instead of SHA512 as you are only using half of the hash. If somebody could explain this to me this would be great. Already confused and this is just creating the key, then the IV needs to be created(not sure what an Initialization vector does) then the encrypt/decrypt function. I think I will struggle understanding this but I am going to try.
Is there an easy way to set the tab order for controls on a form in Visual Basic 2010 Express? I saw some references to a "View / Tab Order" menu item, but I don't see anything like this in the View menu when I am designing a form.
Whenever I name a new project, a file download window comes up. I tried to reset visual studio to default setting and even uninstalled firefox. I'm trying to get visual studio to behave like it use to. url....
In Visual Studio Express 2010 using Visual Basic 2010 how does one set watches on variables so that one can check values whilst a program is being de-bugged.?
Does anyone know how to get my class name and method name dropdown lists again? It's the dropdown lists that are usually above the code. It's just a setting but i can't seem to find it. I don't want to reset my setting btw. I shouldn't have to.
I use a Mac for all my other work like design work and coding in Dreamweaver but would like to know if there is an alternative to Visual Studio Express so that I can do all my vb.net stuff on the mac too.
Is it possible to use LINQ in the express version of visual studio? I am planning on refactoring my project to use LINQ, but I am the only person in my group that has a copy of visual studio pro. Will that cause any problems if someone using the express version has to modified my code?EditI realize that the graphical tools are not available in the express version, so my question does not pertain to those. I am more interested in the actual code, which I assume will work
When creating a new project I get an messages stating "Access to the path 'C:userscontrollerAppDatalocal emporaryProjectsMazeMy ProjectAssemblyInfo.vb' is denied.
Estoy trabajando con visual studio 2010 express, que alternativa tengo de crear informes, ya que no viene con crystal report ni puedo descargarlo al parecer porque no es compatible.
I've got .net v4 installed, and the SDK, and I've managed a Hello World msgbox winform .exe app using the free IDE "SharpDevelop", but that doesn't seem to have an Immediate Window which I'm a bit lost without. I also tried MonoDevelop but I couldn't get the Immediate Window there to work, and worse than that, I couldn't even find a way to design forms and plonk down some controls! I think their main interest is C# rather than VB? So it looks like I'm going to have to try the crippled Express Edition from MS - which feels annoyingly limiting from what I've seen - but I'm struggling to understand exactly what missing features would halt me in my tracks.Basically (pun intended, sorry) I'm hoping to see if I can upgrade myself to vb.net from some VB6 dabbling a few years ago. From what I've read it seems mostly quite manageable, I can understand the "everything's an object" concept, etc.
But, would I be able to produce useful software, deployable around the office with proper msi installer packages? If not, then I just won't have the motivation to progress beyond a few little experiments. The question is - can I actually do anything worthwhile without risking the waste of a considerable sum of money if I were to shell out for an uncrippled version?
I'd like a redist package (full single download) instead of the web installer (tiny single download, massive multiple at-runtime downloads). Anybody know where to get one?It never hurts to try. In a worst case scenario, you'll learn from it.
Visual Studio Express 2010. Windows Forms Application. New MDF Database. Add a table, put some data in it. Now, from the data sources window drag a DataGridView over to the Form1, drop it. There is no BindingNavigator created with it, so I drag on over there from the toolbox. Run it and the BindingNavigator does nothing. Why/how do I make it talk to the DataGridView?

I am having trouble using T4MVC VB with Visual Studio 2010 Express Edition.I can reference the T4MVC classes in my controllers, but I cannot access them in my views (where I actually need them).In the view, the following code is overwritten by intellisense as if the class MVC is invalid.[code]Which generates the error message 'Home' is not a member of 'Mvc'. It seems that in the view there is an Mvc namespace hiding the MVC class. This doesn't exist in the controller.After playing with it some more, it seems the classes aren't available in the View no matter what they're named. What decides what classes and namespaces are available in the view? The classes continue to be available in the controller, regardless of naming as well. I presume there has to be some filter or limit on what is available in the views?I was just watching this excellent video from Phil Haack, and it game me a clue.I need to modify the <pages> section in the web.config file. Now the question is, can I get that to use a class that's not in a namespace, as the MVC class is by default, otherwise I'll have to modify the T4 template to put it in a namespace and include that.
I've got an old legacy application for communicating via serial port to an embedded controller communications bus. that someone else developed.The application is written in VB6, and is structured as two projects - a DLL to handle the connection and communications logic, with an application GUI project.I was hoping to be able to write a new application GUI (in C++ ideally) to use the existing DLL as-is, but I'm having lots of problems working out how to import it.So I'm wondering, is it even going to be possible to use this old DLL into a C++ project as is? or is it possible to import into a C# project? or a VB.NET project? (would prefer not to use VB, but can if I have to)Where I am now: I have the existing compiled executable and DLL, and these run on my system.I also have the project files, and they're all readable in notepad++ but I don't have VB6, and importing the project into visual studio VB.NET 2008 express isn't at all straightforward. Especially not without a working example to dig through and play with first (DLL project may be importable, but has 50+ things indicated as needing changing in the upgrade report. It also seems to be ignoring three .cls files that look very important to my not particularly VB6-savvy eyes... The application project has a message in the upgrade report about something "missing a design time license" and the only project files that actually seem to come into the project explorer for imported project is the project file itself, and the assembly info file.)
Most examples of how to import a DLL into VS C++ assume you have a solution with the DLL project all compiling nicely alongside your project that will use it. Or at least a .DLL and .lib and .h file... I spoke with the original developer of the code (in another city, we don't work directly) and got a .lib to match my .dll, but still have no .h file.I'm usually fine to bash through something new, but without a baseline working example of the project even in VB6 that I can get my understanding from, it makes this very hard. Also a lack of similar questions anywher google can find them on the net makes me wonder if this is something i should be even attempting.I'm working on getting a non-express copy of visual studio if that will make any difference (express worked fine for everything up until now so I never needed anything more) but that will take a number of weeks, most likely.
I'm trying to create a simple file downloader (with GUI). I'm pretty new to Vb.net and I didn't find any usefull information about this in the books I own. All tutorials in the wild are making me more frustrated, since the snippets I use, in most cases, are different classes.What should I use? HttpWebRequest/HttpWebResponse or FileWebRequest/FileWebResponse?How do I save the ResponseStream to a file ?Is it possible to use ResponseStream to define the kind of File (FileInfo) Class to get basic file information (size, extension, etc) is it generally neccessary, if GetResponse().headers gives you most of this info ?
My code, which sucks, because I do not know how to realize the saving....
Private Sub btn_downloader_Click(ByVal sender...) Handles btn_downloader.Click 'e.g http://codeigniter.com/download.php' Dim fileUrl As String = txtBox_url.Text Dim webUri = New Uri(fileUrl)
[code]....
but I don't know what the buffer is and what it is for. Should I set some static values or any dynamic which deppends on Stream-data ?
I'm trying to add a folder and some files within it to a Visual Studio 2010 Express VB.NET project. I have read the answers to questions on this subject here and here. They both say "select folder, right click, and then select Add To Project". But when I right-click in this way, no "Add to Project" option appears. Does anyone know why this is so, and what I can do about it, or alternatively another way of adding a folder to a project?
I am working on a C# project, which needs a VB.NET Class library.I have added the DLL reference of VB.NET Project into C# project.This works fine, but sometimes I need to debug the VB.NET project or pause the project and check the variable values of my VB.NET Project.Is it possible in Visual Studio 2010 Express Edition?
I have been learning about working with databases and VB. I have coded the connection string for a MS Access database to my VB project but i cannot establish a connection with my sql mdf database.
The code i used to connect to MS Access is:
<Dim dt As New DataTable()/> <Dim match As String = ""/> < Dim connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
[Code]....
What is the connection code in order to manipulate data from the mdf file. Is it similar to the above code.
I have Windows Vista Business on my machine and running visual studio 2005 (Version 8.0.50727.867 (vsvista.050727-8600)) as well as "ENU Service Pack 1 (KB926601)" and "Update for Microsoft Visual Studio 2005 Standard Edition - ENU (KB932232) "I'm trying to connect to SQL server 2008 Express via Visual Basic and I've gone through all the forums to try to resolve my issue and it seems that I have to install " Microsoft Visual Studio 2005 Service Pack 1 Update for Microsoft SQL Server 2008 Support" However, when I try to do this I keep on getting the error "The upgrade patch cannot be installed by the Windows Installer service because the programme to be upgraded may be missing, or the upgrade patch may update a different version of the programme.
