Sharing Application Settings Across Many Applications?
Apr 28, 2011I have several different applicaitons that were originally created with Visual Studio 2005 / .net framework 2.0 / Windows XP that got common settings from an App.Config file on a network share. Each of these applications has an app.config file with the following:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings file="\fileServerconfigcommon.app.config" >
</appSettings>
</configuration>
I am now trying to make these applications work in a Windows 7 / .net framework 3.5 / Visual Studio 2008 environment and can't seem to access the settings in \fileServerconfigcommon.app.config in the same way the old environment allowed. I'm wondering if there is some new way to do this. I need to have the applications read their settings from a common file on the network share (having the applications take their own copy is not accpetable).
Sharing Memory Between Applications?
May 11, 2009I have to implement some way of communication between 2 applications:
Program 1 is receiving data at a relatively high rate (sometimes up to 100k in a second). This application receives the data, does only very few computations and saves the received data to disk for later in-depth-analysis or just recall.
Program 2 shall do some real-time analysis on the same data which may at some point become rather complicated.
It is necessary to split up the 2 tasks into separate programs because the data has to be saved under all circumstances and without losses. Program 2 is still in a development phase, it has to be improved, recompiled, debugged. This shall not disturb the data collection and archiving.
Since application 2 has to go through all the data that program 1 receives it would be slowing down everything very much if the programs had to communicate e.g. via TCP. Therefore I am looking for ways to have some shared memory or whatever else might make it possible for P2 to access the data collected by P1 without too much overhead.
Sharing A Class Property (field) Between Applications?
Feb 13, 2012I have an 8 bit digital output board used for device controlling. Each external device needs one bit and is controlled by a different application.I have written a class library and the class DigitalOutputPort (VB 2010) that envelopes the driver that manages the 8 bit port. Each device application uses this class, creating its own instance.
In order to set a bit of the digital output port, I have to write a byte to that port: this byte is the bit mask for all 8 bits together: to set HIGH the bit number 0 - 1 - 2, I have to write 7 on the port, to set HIGH all 8 bits, I have to write 256, and so on...
All works fine when only ONE application uses the class. But if two applications want to set its own bit on that port, I get problems because I do not know the current value of all bits set by other applications (the driver has not such function) and, of course, I cannot change one bit without changing all the other (if I do not know the current bit mask)
Normally this looks like a typical case of sharing data between two application and my first idea was to write the current value of the port in a file on the disc, where all application can access and read it. But it seems to be too much heavy for this simple problem. Moreover it could also creates performance ans reliability problem.
Then I though about using a shared field (property) in the class. A shared field preserves its value between all instances of a class: but is it also true between instances from different applications? I cannot find more info about this last point, I have to make same test.
A third way would be that I create just only ONE instance of the class DigitalOutputPort, one for all applications.The first application that needs it, create the object, all other applications will used the already created object.I like more than other this way, but I do not know if and how it can be done.
VS 2008 Sharing My.Settings Across Solution Not Just Project
Oct 9, 2009It must be to close to the weekend, but I thought I read at some time an article of an easy way to have a common settings file for both application and user settings across a solution.
I currently have a Solution that contains 4 projects. Each of these projects need to access the same set of settings and be able to update the user settings. Is there a way to do this utilizing the My.Settings functionality?

Sep 29, 2009I just finished my program which has a refference to mysql.data thats a dll right? When i build the application its not working on my friend's computer why?...probably cause this dll is missing. (net framework matches its not the prob) How can make it work? do i place the dll at the same location as the executable ?where do i find this dll? I dont want to publish my application just the executable and some extra files probably no need to install on another system to work.
View 14 RepliesForms :: Sharing Settings XML Document Between Forms?
Dec 26, 2009I have an application built that has several forms. I use an XML file to store settings data (mainly folder names for data output) and I need each form to be able to access and modify the data. I'd also like each form to access functions from a main form (such as file parsing functions). I have read articles about properties and inheritance but I need some guidance as this topic is pretty confusing.

View 4 RepliesMy.Settings.Upgrade Stopped Preserving Settings After Visual Studio And Framework Were Upgraded?
Jan 13, 2011The company has been using Visual Studio 2008 and .NET Framework 2.0 for approximately 2 years. During that time we released several versions (4.x.x) of our program to the public and were able to preserve the user's settings using My.Settings.Upgrade.During the past development cycle we upgraded the program to Visual Studio 2010 and .NET Framework 4.0 and changed the version to 5.x.x. Now, when a user upgrades from 4.x.x to 5.x.x they lose all of their settings.However, in all upgrades after that point (ie 5.0 to 5.1) all the user's settings are once again preserved.I checked C:Documents and Settings<USER_NAME>Local SettingsApplication DataCompanyName and it contains two directories:
ApplicationName_Url_aaa ApplicationName_Url_bbb
where aaa and bbb are 32 character strings. All of the user.config files for the 4.x.x releases can be found in the ApplicationName_ Url_aaa directory. All of the user.config files for the 5.x.x releases can be found in the ApplicationName_Url_bbb directory.Based on this information it seems like something changed when we converted our program to VS2010 and Framework4 that is now causing a different 32 character string to be generated. However, we have been unable to track it down.

Application.Settings VB 2005 - Save Arrays Using The Settings System Object
Jan 14, 2009I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.
View 3 RepliesClickOnce Overwrites User Settings Settings .NET 2008 Cant Use Registry UAC Causes Error
Aug 5, 2009I am rewritting my application to conform to ms standards. We used to save all settings to registry for user settings, servername, size and locations.so we are now saving them into My.Settings app.config the only problem is that each time there is an update clickonce will isntall the newupdate but now all settings are loist and user has to save everything all over again..
I am trying to follow the book here but it seems i keep getting stuck somewhere. registry has worked fine for years but i understand we must move on, but if stuff like this happens then i just wasted a long time converting all code to conform for it to not work..

VS 2008 Settings Are Read From App.config Instead Of Settings-file
Oct 30, 2009I have created a settings-file for my plug-in-based app. When the mainApp writes the settings to the file, the pluginApp should read the settings from the settings-file (when opening or at runtime even better), but somehow it reads the settings from the app.config-file. This means that the pluginApp never will read the settings according the values of the file.

Sharing A Private Sub?
Jul 10, 2011how to make projects which span multiple files and classes just fine. I've had big multi-file things working.I've been told explicity that my classes have to be private...yet at the same time I'm supposed to have a main method elsewhere and somehow call a menu in my main working file.I can get the program working perfectly when I do it in a logical manner but I just can't figure out how to call a private sub. I keep getting the error reference to a non-shared member requires an object reference.I've tried breaking the rules a bit and making one initial sub which is public, shared, etc... but all this does is delays the error until it tries to call its first private sub.
View 3 RepliesC# - Sharing Code Between 2 Projects Without A Dll
Dec 2, 2010How can I have code-sharing between two projects without making a dll?
The issue is: I have a tool that syncs users & groups from LDAP to a database.
Now the tool is a windows service, but testing it as such is very difficult and time consuming.
Which is why I made a console application where I can test the LDAP syncing, and then just copy the respective sourcecode-files over to the service project.
But... keeping the common files in sync is a bit of a problem. I don't want to make a dll, because this probably creates me a problem with the 3rd project, a windows installer (for the service) where I have to use ExecutingAssembly path...
Is there a way to share the code without making a separate dll? Automagic statical linking, so to say ?
Can't Enable Net.tcp Port Sharing
Jul 13, 2011I'm doing my dev work on a Window 7 x64 machine, deploying to a Windows 2008 x32 server. At the moment I'm adding WCF services to some internal apps so that we can build smaller clients using net.tcp bindings that report to the user what the server is doing without running multiple instances of the server. To cut back on how much administration the apps will require, I tried enabling port sharing on my first server app. I'm using the app to self-host the WCF service so they can be easily moved from one server to another if necessary. Here's the code starting the server:
Dim _service_host As ServiceHost
Dim active_server_address As Uri = New UriBuilder("net.tcp", "localhost", CInt(My.Settings.ServerPort)).Uri
[Code].....
I get the following error when I put a breakpoint at the last line: Unable to automatically step into the server. Connecting to the server machine 'nettcpportsharing' failed. The requested name is valid, but no data of the requested type was found. The Try...Catch block housing that code says the exception type is AddressAlreadyInUseException...but when I run netstat I don't see anything else listening on that address. There's no occurrence of 'nettcpportsharing' anywhere in my solution. I've checked to make sure that the Net.Tcp Port Sharing service is started.

Sharing Data Between Forms?
Nov 17, 2009I am working with several RFID readers that perform different function in my vb.net program. Currently each reader port number is hard coded into the respective form. For example, reader 3 operates on COM1. However, this will be problematic when installing on different machines.
What I would like to do is have a "configuration" form where the user can select each reader and then select the COM port. Then all other code references these settings. What would be the best approach for this.
The only way I know to do it currently is to place this information in a small database and then have the forms reference that database, but it is a lot to do for such a seemingly trivial task.
