VS 2008 Global Solutions Settings
Sep 1, 2010
I have an issue with globalising my application settings.I have 5 Projects in one solution and I all 5 of my projects use the same connection string to connect to the DB.before I had added any additional projects, I could control this quite easily from the settings designer (Project > Project Properties > Settings) this will work well for one project.How can I share my settings across to all projects, and if the connection string is modified, save it back to the settings file.does VB support settings at the Solution Level?

So I've been working with DotNET for a few years now; long enough to establish solid preferences for one available element over another, one available logic over another, and then to develop preferences for aspects of elements and logics.
The one that conflicts me the most is the stock Settings construct. It's a great idea - I mean everybody needs basic data persistence that isn't worthy of databasing, right? It's implemented in a way that anybody - and I mean anybody from flat beginner to highly advanced - can benefit from it. It does some heinously stupid stuff, though; for example, it angers me (and I mean full-on, where's my crowbar-OK-now where's the silly @#*! who came up with the idea anger) that the only way to save it is the way that's hardcoded in. The .SAVE method takes no parameters, there's absolutely zero exposure for the save-path to provide a more deliberate location, so the only place any settings ever get saved is in a ridiculously long (and literally arbitrarily designated) user-profile-based path.
So what happens if/when a user is ready to upgrade their OS (or just reformat and reinstall their OS, which the kinds of people who end up on my client list are prone to do just as part of quarterly maintenance), and they want to save their personal application settings to load in the next time around? They either have to hunt out that moronically obfuscatory save location or I have to write special (and I mean riding the short-short-short bus special) code which is more or less a whole new settings class identical to the settings classes implemented in the application to begin with, just to allow them to export their settings to a known location for transfer.
And what happens if a specific setting needs special treatment beyond the basic 'changing' and 'changed' events provided by the stock class? Since any change to the Settings Designer rewrites the whole code-behind property declarations, I can't do it in that code file; I either have to extend the Settings class or get back on the short-short-short bus and write that special 'mirror-class' again.
I'm not much for just general whining though, so some time back I wrote my own serializable classes (designed for specific data persistence, like generic/universal application settings and then also MySQL server connections/credentials and then also form properties and then also application-specific settings) along with shared save and load methods which give me more control over where settings get saved. These classes have evolved over the last year or so until they're actually pretty awesome (even if that's
just my opinion)... I've even implemented full on-disk and in-memory encryption functions for applications that need different privilege levels, to prevent any tampering at any time.
And then a multi-user application project comes along and suddenly each individual settings class needs multi-user support based on the Windows user logged in, and suddenly the stock Settings class is the best option again even though it's still the worst possible option in settings persistence.
So what I want to know from this discussion is this:
How do YOU handle application and user-settings persistence? Is there something really key that I've been missing all this time that makes the stock Settings class more than absolutely worthless (which has been my opinion since about the first time I ever had to work with it)?It never hurts to try. In a worst case scenario, you'll learn from it.

Which is the best way to store global variables, in My.Settings or My.Namespace. The reason I ask is because I need to know certain boolean values if certain forms are open from other forms. At present I am defining Global Boolean variables in My.Application, which give the result I require.

I 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..

I 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.

evrytime i add new controls to a form in vb.net the designer regenerates code and asks me to make corrections, so i have to keep on changing the object declarations to global using the 'global' keyword evertime it regenarates code,especialy dataset objects.how can i prevent this?

I saw that you can also use a "Settings File" (Add new Item)to add your settings instead of the application settings. But I can't seem to write any values to the file. Someone with experience with the "Settings1.settings"?

I set up some application settings for checkboxes on an app and then decided to remove them. When I set the Application Settings to (none) in the designer and restarted the app, the checkbox constantly checks and unchecks itself. I completely remade the app and removed the file that is used to store my.settings in the Local folder of the user's appdata profile. I also made sure to uncheck the "save my.settings" on shutdown.

In our database we have gigantic tables (it was initially built 20 years ago). We are on the process of developing it.
Some tables contain rowversion and optimistic concurrency. We were wondering if there is a way to just correspond rowversion to the modification of some specific columns, but not all of them. In Normal Case, T-SQL which is generated then would be huge.

I have up until recently developed only in-house custom applications and I have never had a need to protect this software with any type of licensing/ protection mechanisms.I'm now working on a new project for a software app that I plan on distributing to a relatively small number of clients (1000 or so) and I need to consider some type of licensing/software protection solution that I can easily integrate into my application.I'm also looking for specific product recommendations (if possible) based on users experiences. With vast assortment of product offerings out there, I'm having a very hard time wading through them all.
I would like to stick with a software option over a hardware dongle type solutions so that I can make distribution and activation as painless as possible for my customers¦but would consider hardware options if need be.I have tried the KeyLOK hardware evaluation kit but it seems to be a little difficult to implement and it would force my customers to wait days before they could initially activate and use my application. [code] License registration and tracking via Internet..Software distribution is very controlled and it's not a techie type user audience, so hacking is not a major concern but I would like to protect the application as much as possible.

I have this little code here in vb 2008, I created a flag var to see if the user has clicked the button "enter" so the flag would be set to true. If its true then the game would begin...
I have a label that says "Press enter to Play", and if the user presses play the flag is true, the label visible is set to false. I have the keydown event to check if the enter button has been pressed, i checked if it works and it does, but the var of the flag is always false in my other subs...
Thats the thing with vb i dont understand is when you make a public variable, and when you change the value of the var in a sub, it doesnt change globally.

I don't really know how to call this...Anyhow... I have two objects (for example, "A" and "B") of the same type/class. I have an event (for example, "Refreshed") in both objects. Is it possible, that when "Refreshed" fires in "A", it also fires in "B"?
Edit: forgot to mention - "A" and "B" don't "know" each other.

I've got a StartUp project (StartupProjectA) in Visual Studio that references projects A, B and C. I've got all of those in SolutionA.My predecessor has previously added this solution to SourceSafe so that there's a SolutionA folder in SourceSafe, containing a StartupProjectA folder, and A folder, a B folder and a C folder.
It turns out, though, that StartupProjectB and StartupProjectC all live in the same directory as StartupProjectA on the local machine, so on the PC I'm using I have a [GeneralSolution] folder which contains a StartupProjectA folder, a StartupProjectB folder, a StartupProjectC folder, and A folder, a B folder and a C folder.My question is what do I do to get the Solutions for StartupProjectB and StartupProjectC into SourceSafe? I've tried adding them, but they all create their own copies of folders A, B and C. What have I missed?
I'm trying to use the Visual Studio SourceSafe integration to get these solutions into SourceSafe. Doing so creates multiple redundant copies of A, B and C. I would like to have one folder in SourceSafe, containing SPA, SPB, SPC, A, B and C folders. I'm not really sure how to do this, because I can only add entire Solutions to SourceSafe via Visual Studio. There's no option that I can see for "Add this folder to SourceSafe and recognise that these other three folders are already referenced in the repository and so don't need to be added."

All the refactoring tools for C# and VB.Net that I have seen only consider the source code in a single visual studio solution.For better or worse, our large (many related programs) system is spread over many solution files, however:All the code is below a single windows folder. Our nAnt based build system, builds all files in a windows folder to produce a single dll (bit more complex then this but not important for this question).Therefore ALL ".cs" and ".vb" files below the single root folder are part of the system.
So I am looking for refactoring and reverse engineering tools that take a single folder as input and act on all files below that folder.(The tools may need some help to decide what "public" and "internal" means, however most of the time "internal" means "in the same code tree" when a "code tree" is a folder that contains code and any child folders.)Now I am being greedy, I would like the tools to create a lot of all the refactorings that have been done and to be able to replay the refactorings. Then I could try out ideal and if they work, throw away my code, get the latest code, you do the refactorings and checkin the code before anyone else changes the files. (Likewise for when branches need merging)

An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.System.InvalidOperationException{"An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object."}i have tried cleaning, rebuilding, build solutions and none is helping, if any1 can think of anything else to try please say, another option would be Their is a bit of software call teamviewer that i use, if anyone would be willing to download it and instal it, it would give them the ability to controll my computer to have a look and see what has went wrong.

In VB2010 Beta 2, after program development, how do I deploy (or create a solution to), programs I have written? Also, how can I change the folder where VB 2010 looks for my help documentation Hope someone can help. I've been an on-again off-again programmer for years, but 2010 just makes my head spin a little...
As far as the solution creation, I've already tried clicking on Project-->Publish, which more or less seems like it wants to upload to a website rather than be stuck on my HD... I don't want to upload to the web;the whole reason I want to export is that I want to think I remember at one time having read something about the about box labels only displaying the new information you stick in them once the program has been turned into a .exe file, but I'm not sure; although now that I've run into this problem of creating solutions, even w/ this little bit of a program (nowhere near complete, something like a sure-to-be-crappy-take on Mass Effect 2.. it's primarily text based); heck, for that matter just about all I write programs for is because "hey.. it's enjoyable... umm... kind of" -- I originally started in college as a Computer Science major, switched to Music, transferred schools, the school I transferred to didn't think I had the skills they look for in incoming students, and from there switched to spanish major.
____, just about all I'd be good for is playing music and localization projects (both in and out of the game industry). Not so sure I'll get anywhere, but I said "what the heck, I'll upload my resume to EA".

I've been busily working on a solution for my JSP page problem using an AxBrowser instead of a WebBrowser .NET control. However - the problem seems to be that whichever approach I use, the "back to results" button on my work's JSP page produces nothing but an empty white page in the results frame. I've compared keystroke for keystroke in WebBrowser control, AxBrowser, and IE. The in-built solutions all fail, but the standalone IE works perfectly.Might the problem lay in the way the form is handling the processing of the web pages in the in-built solutions? Could it be a problem with Asynchronous processing?If so, would it be advisable to try the WebBrowser control in a BackgroundWorker setup? It must be something to do with my application, since IE processes the form correctly.

First of all, I wasn't sure whether this was VB.NET or General Developer content... It's not technically about VB.NET code, but it's not very general either since it is specifically about Visual Studio. Feel free to move it if required.A while back I realized that all of my database connection code was getting very biolerplate. had 'developed' my own method of connecting to an Access database and storing the results. Basically, for each table I create one 'Manager' class and one 'Entity' class. The Entity class represents a single record in the database and has properties for each field.
