C# - When Deploying .NET Applications - Find Out What Zone A Share Is In Relative To The Computer Running The Application?
Jun 8, 2011
Using any version of .NET how do you find out which zone a particular share is classified under. I am having a problem identifying if a share where my referenced dlls reside is in the "intranet zone" or "internet" zone relative to some user machine that is running my .NET application. I suspect this is a problem because I am having a problem accessing referenced dlls from a share on some machines but not others. How can I tell which zone .NET is classifying that share in so I can adjust permissions accordingly?

We created a VB.Net application which includes SSRS reports that runs on my development computer. Do you know of a step by step guide that steps us through deploying the reports on our customer's computer? We will be installing SQL Server 2012 Express Advanced on the target computer then configuring the reporting services then installing the application. The last part we need help with is to install the reports themselves on the target computer.

I have created an application that will run several other Engineering applications from within it.
I have my main form which will have a button on it for each application that has to be run. All the other projects are complete and have their respective '.EXE' files, which I have added to the main project.
I have coded one of the buttons to start an application, this is as follows;
Private Sub btnCoordsCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCoordsCalc.Click
Process.Start(My.Computer.FileSystem.CurrentDirectory & "Hole_Coordinates_Calculator.exe")
End Sub
This method works OK and does start the application. So my question is; Is this the correct way to do it, or should I import the whole project into my main project?

I 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..

I'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'd like to get the clock running on my program which is the clock from the computer and displays it into the label text of my window form. I'm using VB 2008 Express edition and I only get the current value of the time at the moment the application starts but not running as a clock.Is there anyway to do this? I used the line 'Me.Label3.Text = TimeOfDay'.

I have a server (server A) that has several public IP addresses. I am building a desktop application that will run on server A to fetch data from another server (server B) using the httpwebrequest class.
What I would like to do is be able to programatically direct the application to use a specific IP address from the one the server (A) has.

I have two VB projects in one VS2010 solution. The first program brings in about 60 integers every few seconds from my PC's serial port. The second program, published via Click-Once and running on my customer's PC, needs to see that new data every two to five seconds.
Is there a simple and reliable way to accomplish this, staying with VB?

I would like to know if it was possible to share data between several assemblies using the same DLL.
I'm not looking for a workaround using memory or disk files of some kind of pipes to do the job I just want to know if and how:
1 - I can run an App. referring to a DLL which contains a given shared data structure.
2 - Run another App. referring to the same DLL that will use the already loaded DLL and data instead of creating a new base instance.

I want to build a main application that make the autentication process and store the loged user... Then use X and Y applications to ask the current user and depends of the user will have full access partial or none access to the app. In future a Z application could be created and will ask for the current user also. XYZ apps are lauched from Main app, when Main app is closed the others are closed and User ID data is cleared. Of course the main app will handle the log on/log off process.
- Store User ID in a Database is toooooo much for just do this
- Save the User ID in a local file like XML is a security problem
I tried to do a WCF Service but i think its not possible to send data and store in it.The other point is who to handle the instantation issue... each program will access to the same static data not create independent.

just wanted to ask if it is possible to have different applications sharing the same session (i.e. database session)... i'm planning on creating a web-based application and a form-based application using asp.net for web and vb.net for forms but i need to have them share sessions since some global variables will be session based and also authentication to one application should also authenticate on the other.

I have 5 websites running on same server and I have some sql tables that I access frequently. that was time consuming and by defining them shared I pumped them in memory. So my application is accessing those static data tables from memory quite efficiently.
But I realized I did a mistake and I occupied my memory unnecessarily while I keep same tables 5 times for each web application. Now I need to find the best way to share that table only 1 time. my options are;
1) using a local database - sql CE. my original sql database is on other server. so it makes the access slower but I can add a sql CE database(to be honest I never used it and dont know if it gives me anything) to access only these tables while they have static rows.
2) I read over forums that making a WCF using tcp binding. not sure if it will give me any advantage.
3) windows service: is it faster than wcf? programming is defiantly faster as i have experience with winservice but nor sure about performance.

I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.

I have a VB 6 SP6 application that uses DirectX 7 to interface to a USB joystick (Logitech Extreme 3D Pro).The application works under Windows XP Pro (32-bit).I've got Visual Studio and the application running under Windows 7 Pro SP1 (32-bit).
I've calibrated the joystick under Windows 7.The VB 6 application does not find any DirectX 7 joystick device to connect to.Otherwise, the VB 6 application works (GUI, embedded video, serial channel, Ethernet connections).The VB 6 application must be accessing the dx7vb.dll or it would crash.The joystick disc did not provide a driver.I installed the latest joystick Profiler vendor software from the Web.This is my first attempt to use Windows 7 as a platform.I'm not sure what to try from a Windows 7 perspective.

In vb.net, when writting an application, I want to access a batch file that has been added to the project. My question is how to I find the relative path of this file to access it? I have used relative path on the ASP.NET side, but not on the application side. The properties that I am finding regarding the current directory and running directory and the likes are all for the bin directory its in. While I can use the CurrentDirectory() property and go up two parents (....) in the development environment, when I install the application, the structure is not the same. As in the output is in a single folder, not tiered.
Example. c:projectsMyAppindebugMyApp.exe is the running directory
My file I want to access is at c:projectsMyAppvalidate.bat
so "c:projectsMyApp" is what I am trying to capture.

I wrote a program in VB.NET which uses several .dlls that I programed in c++. The dlls wrap some functions from an old version of the program. On my development computer everything works fine but I build a release version, copy it and the dlls onto the target machine and the .exe starts up fine. When the program tries to use a function from the .dll it throws an exception and says "unable to load DLL "c:/the path/my.dll" the specified module can't be found."I don't know if it makes any difference, but I am defining the dll functions in the main vb project using:Declare Function MyFunction Lib "c:/the path/my.dll" (ByVal in1 as Double, ByRef out1 as Double) as Integer.I have checked the .net framework on the target and version 4 seems to be installed same as the development computer. Both are windows XP machines. I have no idea if it is the way I programmed the .dlls or just something with my vb.net project.

I am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.
