I have a windows application developed in VB.net 2005. The application is installed in several machines.Is there anyway when I do any modifications and publish the code it updates in all the machines.
PS: All the machines are connected to internet.
I just can't seem to establish a connection between my two P2P applications over the internet(LAN works perfectly fine).
I have tried the following.
- Disabling Firewall
- Changing Port
The only way I can establish a connection is if I'm connecting to the same computer using the universal IP or the local. Does anyone have a fix for this? Oh and here is the error that I receive when trying to connect over the internet:
System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 255.255.255.255:8787
at System.Net.Sockets.TcpClient..ctor(String hostname, Int32 port)
at P2P_Client.Form1.Msgtxt_KeyDown(Object sender, KeyEventArgs e) in C:\Users\Administrator\Documents\Visual Studio 2008\VB Projects\P2P-Client\P2P-Client\Form1.vb:line 32
I'm trying to modify an app.config file that is not part of my .net application.My key needs to be unique and appear under a static key (Server1 or Server2) as the other application reads these values line by line, associating the database(n) value with the server(n) value.I cannot see a method of using the standard app.config methods against an external .config file, so I'm using the Xml Document class.[code]But cannot find a method of retriving the Key to check if it exists and more importantly increment the value?
View 1 RepliesI have an application which takes input on a local machine and sends it to a database stored on a server. I'd like to be able to deploy my application over a number of computers (all on the same network), all of them updating the same database (on the network server).First of all, will this be possible without putting together a completely new application to handle all connections to the database and sorting the entries?
View 7 RepliesI need my application to update as it is on multiple computers. Will the program update and work if I just replaced the files in the application startup folder with the files from the newer version's application startup folder?
View 6 RepliesFirst of all, I hope my intention is not missconcept.I would like to add an update from the internet mechanism for my newly VB.NET application.The idea is simple. That is, I ZIP all of the binary that need to be changed, upload it in my own hosting site, and download it using my Update Application, extract and overwrite the existing binary.
It works, quite well. But the problem is, the size of the binary itself is quite big (around 36MB). I am thinking of patches. That is, can we upload only the patch file, it surely make the download small isn't?
I have created an updater for my application. When the application starts the user can launch an updater that will check for the latest version. Download it and copy the files to where the installation is.
Everything works fine.
However, I am looking for a more robust technique. And I have discovered it is better to hash the files on the web server with a hash algorithm and then when they have downloaded use the same hash algorithm to compare the hash values. If they are different either the files were corrupted when downloaded or some modified them without permission.
However, my problem is where do I store the hash values? I was thinking of hashing the files, and storing all the hash values for each file in a text file, and my updater will download that text file.
I am not sure if that is the best technique to use of not? Is this the normal and best way to do this?
I am working on moving applications from Windows 2000 to new server Windows 2003 R2(64 Bit). I noticed that there are some VB programs and config files for those programs have been placed in Windows 2000 Registry. Some other applications are using them from different servers.Why do we use registry here? How can i move these to registry in windows 2003? Can I just move these or do I have to write VB programs to place them in 2003 registry?

View 3 RepliesI have a scenario that has been troubling me for years. If you have to connect to a database or other service (like a web service) using a username and password, where would be the safest place to store this information if you are connecting through a .NET assembly? I understand that you would have to encrypt the password, but then you run into a kind of chicken-egg problem -- fine -- you can encrypt it, but then where do you put the key?In .NET, you can't hardcode the password because you can decompile .NET code.
I looked at using assembly based rights with Isolated Storage, but MS recommends against storing unencrypted secret items there because priveledged users can gain access, so again, we are moving the problem from point A to point B. So for examplem, a domain admin with no need to know about the information in a database would be able to get access because of the ability to be an admin on any workstation on the domain.You can encrypt App.Config and Web.Config, but I believe priveledges users can access the keys. I think you run into the same problem with DPAPI.
I had considered storing the passwords, encrypted in a remoted database and getting them through OS authentication, but our department prohibits the storage of passwords on database servers. I am pretty sure I am stuck and wanted confirmation.

View 6 RepliesI have an application (.net 3.5 app) that depends on odp.net (11g). I had installed the odp.net on the production machine, i deployed my binaries. The program works fine, however it displays an error like this:This application has failed to start because MSVCR71.dll was not found. Re-installing the application may fix the problem.The machine has Windows 2003 R2 as OS. This error occurs on the catch Oracle Exception block of my code. The program is supposed to display a message box indicating the error. It works as expected in my development machine..
View 2 RepliesI'm a first time visitor and poster, but I'm definitly going to stick around. I'm running an old version of Visual Studio .Net Academic 2002 and the .Net framework 2.0. I'm stuck on an issue regarding the deployment of a few programs I've thrown together. They all work fine on my development machine, but the problem they all use SQL Server databases, and I can't find any specific help on deploying a windows application with a database on a machine that isn't set up basically just like my development machine.
I know that I need the .net runtime bootstrapper on the target machine, so I can run basic programs that dont use SQL databases. That's no problem. But what about programs that make heavy use of databases? How does one go about deploying it on target machines? Is there a SQL server bootstrapper?

I didn't know where to post this question so I hope I put it in the right forum...I am not new to Visual Basic, however I am definitely not an advanced user. I would like to build an application that would allow me to interact with other programs on my computer. For example, if I were to build an application that could control iTunes, how would I go about this?
Or, I am looking to make an application that would allow me to do little things on my computer like disable my track pad if I have a mouse plugged in. How would I build something that could interact with windows (or iTunes) like that?
I have a basic VB.Net application that gets data from some websites and then send them to a MS-SQL database automatically.

I'm running into some strange exceptions coming from a few workstations that are running one of our Windows Forms Applications. The application is written for .NET Framework 2.0 and coded in VB.NET. We've re-imaged the machines a couple of time but not matter what we do, the same problem occurs. We are not seeing this problem with any other machines besides these two. Below is the exception message and the Stack Trace. Can anyone provide any insight as to why this may be happening?
