I'm gonna make a ROV and a UAV. It all gonna be controlled by my computer.To controll the units, I'm using Microcontrollers from Atmel.So what I'm trying to do now, is to implant cameras wirelessly.I'd liked to insert cupple of them, or cupple webcams connected to my USB-port.Is there possibility to have 2 or more cameras in my project?
View 1 RepliesHaving been the victim of a robbery recently, I have turned my attention to web cameras used in conjunction with VB as a security system. I am well aware that there are many commercial products available to do the job but using VB has captured my imagination from a coding point of view.
There is a very basic bit of VB code that I copied from VB-HELPER which also appears in many other web sites but none really explain what the various lines of code actually do. The code is posted below:

I need to capture still's from 2 different video cameras. I am using a 4 channel usb dvr. I have tried to use DirectShow but I only get 1 camera. How can I get a list of all the cameras connected to my pc. I use Visual Studio 2008.

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.
I am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.
So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.
A colleague has written a useful tool. He wrote it as a standalone tool, but it works even better as an includable dll, though it needs a bit of other functionality for it to be a really good drop-in component. What I am wondering is whether a project can be compiled as both an exe and as a dll?
There are alternatives, such as having a dll version and an exe version, since the dll version needs to include a few different methods that the exe version doesn't need, but this alternative sucks, since it would mean changing two sets of code.
Another alternative is to build the dll, then change the exe to be a project that references the dll....and does nothing other than calling one method in the dll. That kind of sucks, too, but not as bad.
I want to be able to use his module in some of my programs, and it really should be built as a component rather than a standalone app, but I want to know whether there are other options that I haven't considered.
I have a VB.NET project in Visual Studio 2010 for an Excel Add-In.I use the "My" namespace,and in general it seems that the "My Project" folder contains configuration information about the project.My problem is that I need to change the name of this folder, because my version manager system won't accept spaces in file or folder names.Edit: There is a hacky way to do it, by renaming the folder and changing all references in the .vbproj file.However, the may work for a command line generation, but it won't work the next time the project will be opened in Visual Studio. The IDE will create a new "My Project" folder, and complain that it can't find the settings in it.
View 3 RepliesThe situation: when i build my project (or publish) Visual Basic 2010 makes and exe and a couple ddl files. when i run the project with the .exe and the other files the program works perfectly.
My problem: I want to share it with friends and it is just a verry little program ( a n internet radio) so i want it to be 1 .exe with out any other instalation needed so i can easly share it to anyone who wants it. when i make an even smaller program and Debud->build it, it is only 1 exe and no instalation needed. so is there a way to make my program to 1 exe only?
well until a few day ago. I don't know what I have introduced to cause the problem but now, whenever I load the project, VS 2010 (SP1) crahes. If I delete the project's suo file, the project loads (really quickly) and all is well until I exitVS 2010. When I re-run it and try to load the project, it crashes again unless I delete the suo file.The program can be built for x64 and x86. Now, when I reload the project (after deleting the suo file), it comes up in Debug - Any CPU mode. I can change from Debug to Release and from Any CPU to x86 but if I try and change from x86 to x64, VS 2010 crashes.This is not always the case though. If I build the x86 version and then switch to x64, all is well and I can build the x64 version. Obviously, there's something wonky going on.

View 5 RepliesFor 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.

How do you export your project as an .exe in VB 2010
when you go Project > Publish "Project Name" it just makes an Application Reference rather than an .exe
Having just downloaded the Visual Studio 2010 Ultimate Beta, I decided to put together a little application I coded under 2008 VB.Net.when I click on "New Project", select new Windows Form Application project and try to open it, I get the following error dialog box & msg:"Unable to cast COM object of type'System.__ComObject' to interface type 'Microsoft.VisualStudio.Editor.Implementation.

when I open my project in VS 2010 (File - Open Project - *.vbproj) my project loads just fine. I can run it just fine. But, when I change something -anything at all- and run the project, nothing is changed. I can even save, close and reopen the project with the new changes, but it still runs the old version.
For example: I open the project, with Form1 that has 3 buttons. I run the program and I get Form1 with 3 buttons. I stop running, add button 4 and hit play... I get Form1 with 3 buttons.I save the project, close it and open it again. My Form1 design shows 4 buttons. But when I start it, there are only 3 buttons...It must be something inside the project, cause this happens on 3 different PC's where I have VS 2010 installed.
