I am working on a VB NET project and had the strangest thing happen.I created a class file(just like a dozen or so I have already created). I wrote in the code to access it. The autocomplete found the class, filled it in and colored it blue, just as it should.But, when I run the app, I get a type is undefined error.
There is nothing in the class yet. And there is really no code to post..it is as straight forward as I described.I tried restarting VS; Deleting and recreating the class; Deleting the class and creating a new one with a different name.
Is there something in the VB NET configuration I can check to see if it is not being added somewhere?
I found the problem. I have 2 projects in one solution. They both share some classes that were trying to use my new classes. When I hit F5, both projects are compiled, and since I hadn't shared the classes with the second project, it errored.
So, now my question is changed; How do I specify to only build the specified Startup Project when debugging?

Working around an issue where my jquery datepicker does not display after postback within an update panel.

Am I approaching this in the correct manner? Any other suggestions to ensure my datepicker remains usable within the update panel?Thinking this may be due to the fact that I have the controls nested within an update panel... several of them in fact.
I am taking in two html files and creating one out of them. To do this I am opening the first html file and not writing out the closing </body> and </html> tag and opening the second file and not writing out the corresponding opening tags, as well as the <style></style>section. I start a streamwriter, and write the lines out to it, and then close the streamwriter. My problem is that the output file is filled with strange characters. I've tried opening the streamwriter with different character sets as the third parm, but all this does is change the characters to different strange characters.It says charset=windows-1252 at the tops of the input files (and the output files for that matter - since I'm just reading stuff in and writing it out - with the exceptions mentioned above).Questions;First, do you think I am properly approaching appending two .htm files together?Second, how can I eliminate these strange characters.

I'm using Streamwriter for the first time with my project which consists of 2 forms.

At this point I get the error "conversion from string to type single is not allowed." [code]

This is the compiler error BC30201: Expression expected. The line that caused it is the Dim sw line.
I am using the Streamwriter to send simple messages to other machines in my office. But i hit across a problem today which i never thought about. If the computer im sending the message to, doesn't have the listener running, the sender crashes out. Is there anyway to trap the error, and deal with it nicely (i.e a message box) instead of the app quiting?
View 3 RepliesI have a testing platform that allows data to be posted to a real time collection system. It uses the StreamWriter object to send both HTTP and XML formats, It works fine, but there is a new request to submit uploaded files. This again works fine, unless the files are over 70k (we need to test upto 3MB). If it is over 70k, the response is the content-length too big. I have changed it so that the content-length is now set dynamically, dependant on the size of the file uploaded. However, when the StreamWriter.Close() runs, the execption The request was aborted: The request was canceled. is generated, with the InnerException Cannot close stream until all bytes are written.
From what I have found on the web, the solution is use StreamWriter.Flush(), but this code is already in place.

I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).

I am trying to use page methods to call a function and I am getting a "PageMethods is undefinded" error. I have used them before whilst using C# but not VB so I'm wondering if my syntax is wrong as all examples I can find are C#. I am also wondering if it's because my scriptmanager is on the master page?

View 1 RepliesWhen you've finished a program and you're trying to distribute it to the mass public. How is the best way to go about doing this? What sites would you post your program on and getting the word out that there is a new program on the block and it does xyz. This is directed to freeware so there wouldn't be any advertising.
Sorry for not explaining it very well the first time.
Alright, so I've got my program and it works, but I have to pump out updates every once in a while. If I can get it so the code will let me have my text file with any number of lines for my array, then I can simply send out a text file and update done.So here's what my code does:
Define a record of arrays, two items, a unicode string (Japanese/Korean text) and then an English translation for the text.I read in the file, it's one item per line, unicode string and then the translation.I have it preset with a defined upper bound for my array, but if I just took out the define and leave the upper bound as limitless, then it would work if I just updated the text file. Problem is, I don't know how to do it with stream.reader (I think that's what it is) because I learned a different way in school. I want to do something like Do While Not EOF with this, and loop it reading lines from the file.
Would it work if I change the array to no upper bound and then simply use Do While Not EOF with stream reader?

I am currently attempting to create a VB.Net script that pulls up information on installed printers. I am using Visual Studio 2010 SP1, and as my target program needs to run on older machines, is currently built using .Net 3.5.Looking online, there are several methods on how to do this, one from url...the code is supposed to use System.Management as you can see. However, after importing System.Management, Visual Studio throws an error and states that ObjectQuery, ManagementObjectSearcher, and ManagementObject are not defined.a quick look at the MSDN forums shows that ObjectQuery is a class of .Net 4, 3.5, 3.0 and 2.I figured the error might be because I didn't have the .Net 3.5 SDK installed, so I installed the .Net 3.5 SP1 SDK to no avail.just to make clear, I am importing System.Management at the top "Imports System.Management"
