Incorporating Networked DVR Imagery Into Forms Application
Feb 18, 2012
I'm working on a windows forms application and would like to incorporate a feature that would allow me to pull the video stream from a networked DVR source. I have an existing desktop program that I may be able to use to snoop out some of the protocols used, but I have absolutely no idea where to look for a library or api to actually display the video.
Has anyone successfully done this? (Connected to a remote DVR, played realtime video in their own application)

I have made a registration program. Making use of mysql database. Can I still use the traditional programming for client applications. If I want to network it. Do I have to modify the codes a little in order to make it work?Do I have to install wampserver only in one computer?

i'm working on something like a slot machine reel spinning with images on it.I've constructed a long image, dynamically, and have that image now stored in memory.I'm able to simulate that image "spinning" nicely by moving it vertically within a panel, and having it repeat. This is taking place in a separate "timer" function.
This seems to move quite smoothly until (on some machines) I output a bit of audio. I'm using the format:
My.Computer.Audio.Play(SoundFile3, AudioPlayMode.Background)
The SoundFile3 is simply a physical path to an audio file.When I call this function for the audio, and when it's not a powerhorse pc, it disrupts the spinning, and the spinning acts a little crazy/random.
Is there a more efficient approach for audio, like storing it in memory ahead of time?I'm tempted to go the multi-thrad approach to try to get the option of multiple sounds at the same time, but I don't know ifthat will help or hurt the situation. And I don't know how that's done.

I have made a very small (only one form and no database operations) but nifty application and I want many people to be able to use it. My question is: As I only need a very small part of the dotnet framework, is there a way to let the compiler (or so) grab only the parts it needs for the .exe/.msi file, so that users don't have to install the entire 3.5 framework just to run my tiny little app?

I am not able to find the Exclude Command in VB 2010 Express. I have no idea which version of Visual Studio it is working with. I've got one 217MB VB 2010 Express file and many 2008 VB Express files with one of them measuring 31 MB. There many other SQL files and .Net Files.

I have an engineering firm and our website was built using Visual Studio 2010 / asp.net 4.0 / VB. Recently, a client (GM) requested that we have a knowledge base where they can input their questions, and we can answer 'em. Kind of like a FAQ, or a Lessons Learned type of thing. But it'll require that they'll be able to log in and ask their own questions.
For instance: Q: How would I incorporate multiple machine vision systems into a bead detection application?A: You would need to use a software such as PPT and have multiple fixtures in order to assimilate the cameras accordingly.
I'm terrible at databases; I can basically run an SQL query, and that's about it! lol. And I'm not a programmer by trade. Can I do this without a database? Can anyone guide me in the right direction here? I mean, is there something out there that's open-source, or at least something that's easy to implement?

We have around 2000 staff. Each has a shared drive to store some of their files. This shared drive points to a central location on our network.[code]...
Each user will have a folder within the root "ournetwork" labeled with their username. I do not have to worry about the directory creation as that's already done for me. These users are all tied into our AD for authentication. Folder name == AD username.
We would like the ability to allow our users to access their mapped "F" drive from outside our network through a web page. I understand that the programming involved (assuming it comes to that) will not rely on their mapped drive but rather the UNC path as posted above.
I am open to suggestions on how to get this accomplished. ASP.NET? Is there just an IIS solution like WebDAV? (although client-side WebDAV on win 7 seems to be broken, so that may be off the table).

I think the problem arose because of Windows 7, but when I was at school the program worked. The program fills in the text boxes with information from Microsoft Access. However, my laptop has Windows 7, and when debugged, the information doesn't fill in the text boxes like before. Also, for added information, the school's computers run with Windows XP.

how I should go about getting the names of the computers on a network. And if the comp had file sharing on, get the "tree" of dirs on the computer. Would I need to authenticate myself in order to read/write actual files to it?
how to even get started, so I don't have any code - the best thing I can think about doing is getting the tree of "\\network" or something. (forgot what it was called)
find some code (or give some search keywords or names of APIs) that would allow me to see and write/create files on a networked comp.

I'm planning to make multiple projects, which could connect (or comminicate) together. It's like a designing Network Program. There'll be a main program and some sub programs. These sub programs will send the informations about other computers which is on my network to the main program. If you ask "Why do you need to get infos about other computers?" ,then let me explain. I'm using limited internet connection and I'm not the only one who's using this wireless network. If I get over the limit, I'm paying some limit-upper fee. So, I've to control others internet usage to not to get over the limit. I've just made a small download counter program for my pc, but as I said, I want to convert it to a bigger project, with network solution. Could anyone refer me any resource, or show me any starting point?

My issue, however, is connecting to the wireless laptops as well.
[code...]
I need to grab a list of all networked computers, and I definitely include systems on the wireless
network in that list. I'm just not sure how to approach this. Being able to enumerate through a
'tree' of all networks and systems available would be a major plus.

I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?

I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

My boss gave me an MS Access application that was developed by our former colleague. He wants me to convert that application to VB.Net Windows form application. I went through the MS Access Application. It contains tables, queries, forms, reports and macros. I could not find the programming (Where is the code written in MS Access?). My boss wants the windows application to be same as the MS Access Application (both in design and logic). I don't how will i develop the windows form. How can I achieve this?

I have a VB.NET application that will be launched from Windows Scheduler and will perform periodic database operations to a Sybase ASE system. I performed development and debugging by launching the code from a button on a form, but now I need for the application to run without intervention. Is there a class I can place the code under instead of the Form class I started with? How do you run VB.Net code without launching from a form.

My application consists of about ten Forms so far. One of the forms gives the user the option of choosing the language that all the text on the forms will use. Each Form has a declaration like this
[Code]...
I have this declaration (Public myLanguage As New DataClass.LanguageStrings) where I had intended to keep my working copy of the chosen language strings, so that each Form's Constructor could set the xxx.Text properties using this type of assignment - ... = myLanguage.yyyStrings.xxxString. However, the IDE throws an error at the first occurrence of "myLanguageSet" in the module SetLanguages above, saying that I should use "New" to declare an instance which I can then use, despite the line above that point where I thought I was doing just that. It doesn't seem to matter where I put the declaration of myLanguageSet, I just can't avoid the "New" error being thrown.
