How do I rearrange the Settings variables in VB.Net 2010 to be near the ones they are related to? I edited the app.config file to rearrange them, but when VB loaded again they were still shown in the old order.

View 4 Replieshow would I do a loop with different my.settings variables?
ie lots of variables
My.Settings.numberofsites = 3
My.Settings.SiteDesc1 = Home
My.Settings.SiteDesc2 = Work
[Code]....
This would give me an error as there is no variable called SiteDesc.... but I actually want it to return SiteDesc1, then SiteDesc2 etc.
Im studying vb coding at the moment and im designing a reasonably small text based game using the windows console and so far i have a nice working game but the main problem is that the game restarts when you end the console, obvious i know. Been trawling through pages looking at different ways to save multiple variables for multiple uses such as a save/load feature and most pages have confused me, people asking for help with commands im not common with. So far i've tried using my settings to save the variables in a test program but can't get it to work?I have in settings a variable called gold with a scope of user as an integer and i have this code to try and utilise it
Module Module1
Sub Main()
Dim answer As String

I have multiple Projects in one solution and i want to share settings variables with projects how i can?
View 4 RepliesWhich 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 have several windows open: VB, IE, Explorer... If I happen to close one accidentally, or on purpose, and reopen it, the buttons on the task bar are all messed up. I get used to them one way and I am constantly switching between the windows.Here is my question: Would I be able, in VB, to 'hook' the taskbar and be able to rearrange the buttons?I have no idea what to search for in Google. I happened upon a program once a while back, A REAL LIFE SAVER!. I could just click and drag the buttons using that one.

I have a form with a large GroupBox on it. Inside there are a total of 22 buttons, arranged in two columns of 11. These buttons are basically shortcuts that can be defined by the user. I would like to allow the user to rearrange these buttons by some simple means. (Drag and Drop being ideal.) I have the following code, which allows me to drag the buttons around:

Iam using sql2005 database in vb.net2005
my table's name = tab1
I have 3 fields
1- ID = auto number =primery key
2- IDD = number
3- name = text
now if I add 10 names in the table from (1-10) =1,2,3,4,5,6,7,8,9 ,10
then if I delete name number 6 the IDD field will rearrange it self from( 1-9)=1,2,3,4,5,6,7,8,9 instead of 1,2,3,4,5,7,8,9,10
Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.
I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]
View 15 RepliesThe 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.

I 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 RepliesI 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..
Is there a way to maintain application modified Settings in the settings files after a program update? i.e. I have 10 or so values in the settings file and the users can modify them... when I send a program update they revert back to what I initially programmed them to be.
View 3 RepliesI define some global variables of a class as follows:
Private Class MyClass
Private var1 as Decimal
Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)
i have created a user setting named 'setmeup' as string, scope = user, value = "magical meow meow!".in my code i access it and assign it a new value like this...my.settings.setmeup = "howdy cowboy!"my.settings.save()application.restart()when the application restarts, i expect the my.settings.setmeup = "howdy cowboy!" but when i check its contents its still "magical meow meow!".but when i use application.exit() instead of application.restart() and manually restart the program, my.settings.setmeup = "howdy cowboy!" which is correct.what must i do? i want to use application.restart() because i don't want the users to double-click the icon again to start the program. i want the program to restart automatically.
View 2 Replies1. I can't find the file which reflects changes to user settings. This might be because I just can't find it (I can see a bunch of user.config files but they are all empty - weird!), or...

Regarding 2. - do I need to invoke
Is this all I need? And if so, why are my user.configs empty?

Does the memory used in declaring variables are reclaimed by the OS when these variables go out of scope?Does the memory used be released by setting thier value to nothing? if not, then how can I force the garbage collector to run or excecute at a certain/desired time..How about in Windows Forms..How can we make sure that the memory used in initializing and showing forms be released if those forms were closed?

Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.
