I am an experienced vb6 programmer, even completed MCSD cert back in 2000. I have done alot since then, and I am thinking about learning vb.net where should i get started? From what I have seen briefly, the ADO is some of the biggest change from vb 6
View 3 RepliesI am trying to renew an existing (and not expired) ClickOnce certificate with the same key from the console certificate 'snap-in'. The wizard is giving me an Enroll error saying "the request contains no certificate template information" I don't think the existing cert has a template so can I just hit the 'Finish' button and ignore the error? Or do I have to create a template first?
View 1 RepliesIm using the SSL stream class to connect to a server and authenticate their self-signed certificate. My authentication code gets an error: "RemoteCertificateChainErrors". When I drill down into the X509ChainStatuses, I only see a status of "UntrustedRoot" and status information of "A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider." This seems acceptable due to the self-signed nature of their certificate. I understand that I can ignore this error. However, Id like to do as much as possible to authenticate. I have a certificate from them. Ive been told to add their cert to my root certs somehow. How do I correct my code use this cert in authentication?

I was wondering if anyone could point me in the best direction to becoming proficient in Visual Basic and later maybe other languages? I work full-time as an Information Management Officer for the DoD and I am also a full-time student (CMIT Major) and father. I have to try as it is to balance my time and find ways to get programming practice in but admittedly it has proven difficult. I am currently taking my second class in Visual Basic and had a previous class in Java as well.
Next term I will be taking advanced VB but i don't feel at all like I'm very good at VB, especially not good enough to be taking an advanced class. I desperately want to become a proficient programmer and was wondering if anyone could suggest a good, at-you-own-pace program or instructional books, videos, anything, that would walk me through creating beginner, intermediate, then advanced VB programs and techniques and different ways to deploy applications created in VB?
I code primarily in vb.net. I've been doing basic dependency injection manually and am looking to learn more about DI/IoC and maybe use a DI/IoC framework/container like Ninject. There are lots of examples and write-ups using Java and C# code. I'm looking for the best resources for vb.net programmers. Likewise, is there a particular framework that would be easiest for a vb.net programmer to pick up?
View 3 RepliesI am looking to switch to C#. I come from a C / C++ background but C# is a little different for me. I am switching mainly because of Silverlight and MVVM; all examples are in C#. Any information is in C# and I am confused when I read through it all.
What is a good place to start learning C# when starting with existing C / C++ knowledge?
For a few years I developed websites in PHP, but couldn't get a job doing this nearly two years ago. I spent a year teaching (and if your thinking of teaching, my advice is don't! In the UK anyway), but kept handing my CV out to different web development companies. One of these offered me a job, but the downside (or upside, depending on your views) that they only developed websites in ASP.NET. I made the decision for a career change and accepted the job.
In ASP.NET, you can develop in either C# or VB.NET. The guys I work with are using VB.NET, and I have to say I'm struggling with it. I can understand the basics but it just seems weird, especially as I've come from PHP. C# on the other hand, looks similar to PHP. I'm contemplating learning C# instead of VB, but I'd like to know what other peoples opinions are about doing this?

I'm writing a program in VB.NET 2010 that will connect to the PICkit(TM) 1 FLASH Starter Kit's USB programmer and send it commands to turn on or off something connected to the attached eLab16m board, for example, an LED. This is all done by using the libhid.net DLL. The vendor id is &H4D8 and the product id is &H32.
Update I've written a console program that outputs what's happening. Here's the output:Where it says device with report id 0x10, I am trying to query the firmware version from the USB Programmer.Update 2 I've fixed the problem with the Wacom Bamboo tablet by uninstalling its software and drivers from my computer. The error has disappeared from the command line, but it still shows the 0x10 error.
I need some basic assistance understanding how to mess with bytes. And when I say basic, I mean dumb it down for me, I'm a self taught hobbiest mostly and only spent 4 years proffessionally in development. And that 4 years was a database programmer handling the connecting, retreiving and inserting of data into various databases.
I can't honestly think of the last time I had to do anything with Bytes, but I do know that when I did, all of the functions that actually did anything were written by someone else. So start off, I've been trying to handle them like strings, and that's not working for me (you probably guessed that).

I've been programming in C/C++ for several years and want to learn enough Visual Basic to create GUI front ends for some of my C programs & also so I know that C functions I have written can be called by VB programs that others write. I expect that the C programs would have to be turned into DLLs for this to work.
I have created some C DLLs & created other C programs that sucessfully call the functions in the DLLs. BTW I did this with Visual Studio 2010, would there be any advantages to using other versions?Can anyone recommend a book or a website to quickly get me up to speed on VB while allowing me to skip over the parts that are intended for people who are new to programming?
Many of my programs call functions from the Windows API such as CreateFile. IINM these functions can be called from VB, but it is done differently than in Visual C++, eg: in C++ Create file returns a HANDLE variable, but the HANDLE variable type doesn't exist in Visual Basic. So I'll need to learn enough about how Visual Basic uses the Windows API to pass the file HANDLE from the C functions to the VB calling program & back.
A job recruiter asked me if I could take over writing code for a device that uses Windows CE. He didn't know much about it except that he thought the previous programmer was using Visual Basic, and he thought it might be Visual Basic.NET, along with SQL Server. I'd like to take over this programming job if I am qualified, but I don't know if I am. I have developed code using VB.NET, C#.NET, SQL Server for standard Windows. I used .NET to build programs that run on Windows desktop, and also the WPF platform. I also built ASP.NET and Silverlight programs for the web. In addition I have written programs that interface with machinery using serial and TCP coimmunications.
Would I be able to get up-to-speed on taking over the coding of a program that targets Windows CE? Does Windows CE allow .NET managed code or just C++ and VB6? Would it be advisable to try to get this job or would taking it lead to problems and disappointment?
I would like to learn a new programming language to be able to compile the same code for different platforms.
My background in programming: VB.NET (I have been using it as my main language for the past 3 years), some Java (to which I couldn't really adapt) and very limited PHP. I use a Mac Book with OS X to code.
I'd like to find a PL with a very easy learning curve from VB.NET, cross-platform IDE and able to compile the same for Windows, Mac and Linux.
I am a beginning programmer, so a object-oriented, .net like language is probably my best bet.
I'm thinking of trying to learn VB 2008, and I was wondering if there's an online guide or tutorial to get going from the ground up - from the perspective of a former long-time VB6 user (makes it a bit easier to relate functions in VB 2008 and how they replace older functions in VB6)?
View 1 RepliesCurrently on an internship from my CS degree, we have some down time and I'd like to spend it working through a series of problems (although none too large) that would advance my programming skills and allow me to dip my toes in a large breadth of different topics and areas. Unfortunately, everything I do must be done in vb.net on .net 2.0, without downloading any particular libraries.I've already worked through many of the "code-golf" tagged problems on here and the programming praxis problems posed by dailywtf.

In my friends company the management brought up the topic of moving in the WPF to design rich UIs. Majority of the employees of the company are programmers and only 3-4 graphic designers. The management wants to train the graphic designers with WPF so that their graphics skills could be applied in creating UIs. However, programmers have a mighty obligation for this. They have written several complaints to the management that WPF is not just Graphics but it has programming in XAML. SO the programmers wants to take over UI design as well (in the past programmers did the UI part as well)...... I'm a programmer therefore i'm with the programmers.
What would be the most suited solution for my friends compnay, should they move the graphic designers the WPF or should they train the current programmers to design UIs in WPF?
How can more than one programmer work on the same project at one time? is this possible? it surely must be possible??

View 2 RepliesI have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

View 3 RepliesWe have a server application and a client application that communicates with each other using socket.
When the server application sends 2 messages about 16-31 ms apart, the 1st message is received by the client application with little delay (like 16-32 ms after it was sent). But the 2nd message is received by the client application a lot later (like 200 ms later) than when it was sent.
We already disabled Nagle algorithm (set NoDelay = True) in the socket in both the server and client application.
We are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.now i think it means that it cant find the mysql connecter and data and stuff but the user shouldn't need to have that right? it should come with the app to make it work for everyone
