Mixing C# & VB In The Same Project?
Aug 14, 2009
Can you mix vb and c# files in the same project for a class library? Is there some setting that makes it possible? I tried and none of the intellisense works quite right, although the background compiler seems to handle it well enough (aside from the fact that I, then, had 2 classes in the same namespace with the same name and it didn't complain). We're trying to convert from VB to C# but haven't finished converting all the code. I have some new code I need to write, but didn't really want to make a new project just for it

I'm using the WndProc To get messages about USB flashdrives connecting and removing from the users computer. It works grand. I also use WMI queries to get the info about the flashdrives. It works as it shouold. The problem is when both of these are in the same solution. I ended up creating an extra .EXE that uses the WMI queries to get the drive info and output the info to a CSV file which my Main will parse. I tries creating a seperate class of each and i also tried to make a DLL that I import to no avail.

This is my first post as I don't like to ask questions without making sure I've exhausted all other means. I'm new to VB2008 and programming in general but I'm learning. I want to do several simple tasks. Doing each separately is easy but when I put them together I don't know what to do. For one thing to work all the code must be changed and everything else doesn't work.
1. Plot a graph of data from a DAQ. I can do this by using a Timer1_tick method and displaying the data on the linegraph as long as the timer is turned on. I've decided to stick with this method of acquisition. I want to acquire data for long periods of time (perhaps 3 hours) so a timer is pretty good. No problems here.
2. Apply a filter to remove noise from the plot dynamically as the data comes in so that I get a smooth curve instead of a jagged graph. I know I can do this with for loops if I'm using an array. But how do I do it since I'm using a timer? Here the problem begins.
3. Log every piece of the filtered data that the timer is getting to be exported to a CSV file. I learned how to do this with do loops but not with a timer or array. But I really need to use the timer this time.
4. Acquire statistics for the data like maximum value, minimum value, and average value dynamically as the data changes. I know how to do this with an array of data after all the data is acquired. But How do I do this with a timer while the data is still being collected?
5. Monitor the data coming in to execute an alarm (Or event, like stopping the acquisition) when the data coming in has plateaued and is constant (eg: The voltage I'm monitoring starts to become constant and becomes one constant value) - Ok I don't know anything about this.
6. Execute a mathematical operation on the data that has been acquired (post acquisition) like finding gradients and such. Basically this means "How do I now manipulate the data I have and where is this data stored?"
Here's my starting code that gathers data with a timer. How do I work from here?:
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As
System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Timer1.Enabled = False

My app is basically console based but I need a Form to run in background. Adding a form in the app works but using Form1.Show didn't work, so I used VB.NET Application.Run(New Form1) However, in Form1_Load Me.Hide didn't work. I have no idea why. It works in buttons or other components in the same form.

First let me start off by saying that I have dealt with Winsock for MANY years and am attempting to convert my project over from vb6 to VB.Net.This program was made to handle up to 70 connections at a time and constantly sending data from Server to clients and back.
There is one packet however, that reaches up to be around 177kb when sent. The sockets are set up to sent 1kb at a time.... (No other packet actually uses the whole kb). It seems that after the server sends this large packet... the client receives the data out of order. After debugging and monitoring I find that it normally happens between 3-4kb. While the first 3 are good and in order.My question is, is there a different system I should use instead of just Sockets (I have had similar problems with TCPClient) and/or can someone maybe link me to a sample project that would not have this error?

I am currently writing a VB.net app to control an Integra AV receiver. I have success controlling it via Serial, but it also has a network port for TCP control. I can control it using CommandFusion iPhone app but am now wanting to create a windows app to control it. I have created client/server software that I use to talk from one PC to the which works well. So I am going to use the same client software to talk to the AV receiver. I can connect fine to it, I just haven't quite got the protocol right to actually control it.

Can someone who is using a 64 bit machine help me pintpoint this crash to either the VS2010 IDE itself or one of the plugins I have installed?
It's the code fragment below. When I copy & paste it into the Main() function of a new VB.Net console app on my Win7 64 bit machine, the VS IDE crashes and dies onthe spot, every time I try it.
Doing exactly the same on a 32 bit XP machine, nothing abnormal happens.
The 64 bit machine does have some IDE plug-ins installed, the biggest of which is DevExpress (the free version), so i think either one of those or the fact that the IDE is running on 64 bit must be the culprit.
This is the code. The static variable can also be made a module-level variable, with the same result.

I have a large-ish solution, with C# and VB.NET projects mixed. Whenever I try to o to definitionon a class, property or method thats defined in the other language, Visual Studio just takes me to the Object Browser, which is pretty annoying. Same for debugging: I cantep into a project that's written in the other language.

I'm making an application that will change position of two characters in Word.
[Code]...
Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.

For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

I have a project that I have created, it something like a contact database.It is complete with its own sql server database, and controls and forms.I kinda of understand that I can include this project into another project.This is the tricky part,Can I include my contact project into another project and add more items to the database and forms in a new project?What I'm after is like using classes.My contact database would be like the base class, and the new project would be adding more features to that project.

We are binding most of our text boxes and dropdown boxes to a BINDING NAVIGATOR (with a DATA SOURCE of a DATA TABLE).When the BN is clicked through the text boxes all change immediately.We need to use some non-bound controls as well.First one is 4 radio buttons that when clicked will change a single value in a DATA TABLE.What would be the best method to do this? Should I track when the CURRENTCHANGED event occurs on the BINDING NAVIGATOR.I'm thinking that I could trick this by BINDING the SINGLE FIELD to a HIDDEN TEXTBOX and when that textbox CHANGED event occurs mess with the radio buttons and visa-versa.

I made a change to a project and hve induced a major problem. I have warnings and errors now, but I can still debug the project with the "last successful build" Iwould like to just revert everything to that build but I can't find a way to eliminate the problems I induced or find a way to go to a earlier build. Hopefully I can get back to an earlier version or I will loose the entire project as I can no longer get to the designer.

If I put this piece of code in a new fresh vb.net form, add a button and two labels and start debug I get execution time of about 11.5s.If I put the same piece of code in a new form in an old project upgraded from an earlier version of vb.net, start debug I get an execution time of 7.5s.So I do exactly the same in the two projects but get different execution times.
What do I have to do with the fresh new project to get the same execution time ?I am not interested in improving the code to be able to calculate primes faster. I just want to know what is the significant difference between an old upgraded project and a new fresh one. I am using windows 7 64bit on a 2,4 Ghz Intel quadcore.

I am following the guidelines from [URL]..Mid way through the process they have you rename your App_Code to Old_App_Code folder and compile ... at which point i had DLL's in my BIN folder and i started to repair my aspx/ascx files.
e
Today i find the compiled bin files missing an now all my pages are sqwaking they cannot find the numerous Public Class - Public Shared Function's ... I have verified their build action to Compile but am unable to rebuild an have them regenerate on account of project errors.Advice on how to rebuild the bin or how to properly reference a Public Shared Function? My VB code includes an Imports statement taht used to find the class in app_code.

I'm developing application that is plugable. The plugins are loaded via Assembly.LoadFrom(). In my solution I have 4 projects. A WPF, 2 DLL and another DLL that is a plugin for the app. The plugin project references one of the other DLLs. When I build the Solution and run I was getting an error trying to use the plugin dll because it was expecting an older version of the referenced project. I had to clean and rebuild the plugin project to get it to run correctly.

I am using 8 different vb projects in one solution, beside this I am also using one 3rd party control ion all the projects, while compiling the application it takes around 5 minutes to build the project, While building the application I have observe that it uses lc.exe file which is used for "Reads text files that contain licensing information and produces a .licenses file that can be embedded in a common language run time executable." at this point it takes too much time.

I new to this Forum and relatively new to VB programming. I have read some really good posts here and thought I would ask about a perplexing problem I'm having. I createdindows Form application, built it and deployed it with no problems. However, when I added a small block of code, re-built the app and went to add the app to the Project Output Group in the file system editor the project was not in the Project drop down list. I closed the Setup project and deleted it from the project folder and checked my code and re-built the app and tried the Set Up project again with the same result

Has anyone else had issues with Visual Basic 2010?My visual basic program has been running fine for months but recently every time I try and load a project (any project) the program freezes, then I have to close it down and reload, every time I load Visual basic for the second time I get the following error:
HTML
An error was encountered while opening associated documents the last time this solution was loaded. Document load is being skipped during this solution load in order to avoid that error.Plus when trying to run a project in debug it takes ages to load (around 5 minutes) this has only started happening recently, projects were loading in seconds.

Having successfully tried out nHibernate, I would now like to try using Fluent for mapping. My main project is in vb.net but I would really like to use c# for the mappings since the lambda expression capability makes it much cleaner. Can you have a separate project/assembly for your mapping files without creating a circular dependency with domain objects?

I have a multi-project .NET 3.5 solution. It's ASP.NET based with c# code-behind in all projects except one.I'm attempting to access members from a C# project called "Core" from a VB.NET project. I set a dependency to the Core solution in my solution properties. However, Core. brings up nothing. Furthermore, my other C# projects that have Core-Project as a dependency (in the solution settings), are able to declare Core objects. Example: Private Core.ObjectName InstanceName; Also, Intellisense brings up plenty of info in the C# projects.how I can hook into these members from my VB project?
