Possible To Save Variables In Application?

Apr 19, 2010

I am trying to build a game (out of fun) similar to those text based games like Wars, iMobster (which can be found on Facebook/iPod). And I came to the point where I need to create a Save/Load system. My game currently has 50-ish variables, and it would be nice if there would be a way to save them in the application themselves, so when it is opened the next time they are all there. I know I can write the variables to a .txt file, and then pull them from there, but those are easy to modify, plus that means one file for each variable (right? Unless there is a way to save all my variables into 1 .txt file?).

Aug 20, 2009

I've got a RPG style game I am putting together - mostly to teach myself vb.net. I am using alot of global variables to hold game values.[code]...

My question is -- I am trying to make a "SAVE" and "LOAD" the game's state. Is there a simple way to save the values of all my global variables, without having to type everysingle variable out. Is there anyway to call upon all my global variables at one time, and possible save/load them to a text file ?

Save DataGridView Cell Contents To Variables?

Nov 27, 2009

I am using the DataGridView in Visual Basic 2008 Express with an Access 2000 database.

What I'm trying to do is allow the user to click on the Row Header and capture the contents of the 4 cells in the row to 4 dfined variables. I know that I can capture each cell individually by using the CellContentClick event but this would require the user to click 4 times rather then just once.

Set A Timer To Periodically Save Value Of Variables To Database

Jun 7, 2010

Im currently writing a sort of Tamagotchi game or "virtual pet". It's really basic, it runs on timers and has a health meter, hygiene, happiness etc. The problem I have is when the program is closed it obviously resets the properties back to the origional settings. Is there a way I can save the state of the program so when the user opens it back up it is as the same as of the point when it was closed?[Just had an idea, would I set a timer to periodically save the value of the variables to a database and then have them load the next time the user opens the program, for example if the health was 50% on closing or at intervals it would save the health into a column in a db table then when the user re opens the program call that db?]

Save Variables To Be Recalled Next Time The Program Runs?

Nov 9, 2009

I am creating a very simple game for a project. There is opportunity for bonus marks, and one thing I would like to do is be able to "save" the game. The only thing I need to do is save about 4 variables to be recalled the next time the program runs.

What is the best way to do this?

I have searched Google, and there are ways to link the program to an Access database, but that seams a little extreme. I tried seeing if you can make an XML file to hold them, but I can't really find any good information.

C# - Application Variables Global To Webgarden?

Jan 12, 2010

I am currently trying to program an online drawing program using the HTML5 canvas.the thing is, I need to have the current canvas saved somewhere globally. Static variables work, but they do not get shared across a Webgarden. This results in two different drawings being created.I will have to somehow create a new application object which is shared. I figured I will need an external application holding them.

1) How do I replace the application object with my own?
So either I will have to make my own program and call to it with remoting or use the ASP.NET session state server for application variables. I favor the Session State Server though.

2) How do I use the session state server for my own variables? How do I access it?

I searched high and low on the internet and only found the ideas mentioned above, but no help executing them.

I mainly code in VB.NET, but I can also understand C# code for examples.

A little info on my application:The client side has two canvas objects on top of each other. The top canvas object us used for drawing stuff, the canvas object below it holds the drawing in the end.When something is drawn, it is sent to the server in it's base64 representation. (getDataUri).The server puts this graphic on top of a stored Bitmap object through a Graphics object.

How the changes are being distributed to the other clients, I am working on that right now. Either I transfer the complete picture or each and every change that is submitted. This should work through Server Push. If this does not work thoroughly I will have to save and timestamp changes. A link to the current implementation, which is not currently fetching changes (but they get transfered to the server... With the problem that some reach one instance some reach the other on either w3wp in the webgarden) from the server is here: http:[url].....

Pass Variables From Php Script To Program Application?

Mar 14, 2012

I am developing an VB.NET application that reads data from the serial port and tcp socket, then I'm processing this data and store it in Database server. This application will be started all the time as long as the computer is started. On the server there is installed an apache server with some php scripts representing the "visual interface". From there the users can see the readed data from the VB app. The need is when an event appear in the apache server (such as button pressed), some data to be passed to the running VB app, and eventually trigger an event on it. I've considered some variants like start an timer that reads continuously some tables from the database that the php script writes onto, or read an xml ot text file, but I think that this may slower the communication and it is a source of exceptions or errors.

For example: An user opens a webpage, just to say test.php. On the page there is a button. The user pushes the button. The result of pushing the button has to trigger an event on the VB app and cause sending data trough the serial port or tcp socket. OR - The VB app has a timer that scans for pressing the button on the test.php.

Storing Application Variables In An External File?

Jul 8, 2009

I have been tasked to create an application, for which the requirements may change over time.This application will be a data entry Windows application,of which multiple copies will be running.All data will be written to text (.CSV) files for validation before being uploaded to a remote mainframe system (iSeries).My application needs to store certain variable information in an external text (or XML) file; for example, the file path to shared resources (which may change over time),as well as the specific data fields required by the mainframe system.

My questionsare these: what is considered the best practice for accomplishing such a task, and how would I accomplish it?I am completely new to XML, so I don't even know where to begin, although I am sure that XML is the path to follow for what I am trying to accomplish.

Use Of Variables Across Several Forms In Application - String Manipulation?

May 5, 2010

I am a beginner trying to write code. I am creating an application that is a questionaire with 3 forms that have questions for the user with text boxes, list boxes, and check boxes for response. Some of the text boxes with the user response are on different forms. Will that cause me problems? I would like to write code that will combine a literal string with responses from text boxes and string snippets which are inserted based on check box condition. I think I would like to create the string to be printed to a RichTextBox and then output to peripheral printer. How do I make inserting or not inserting a string based on check box condition? How can I trim the response string to allow a output string without annoying extra spaces and such?

Variables - Created An Application That Communicates Via System.net.socket

Nov 9, 2011

I Have a problem with vb.net. Basically I created an application that communicates via system.net.socket. on the server side of client connect, and a thread checks whether there are new incoming data. if there are data, puts them in a few tread declared variables, together with the "index" of the server. once this is done through "INVOKE" calls a routine that checks the incoming data andperforms an operation based on the data. I'll see what I do not work

Dim returndata As String = System.Text.Encoding.ASCII.GetString(data)

TextBox1.Text = ("DATA : " & returndata & "Socketindex =" & socketindex.ToString & " Index=" & index.ToString)

But that does not appear in the texbox, appears only "returndata", the rest c 'is same thing with the messagebox, individually, can display a messagebox with variable,but when I try to make a messagebox that displays them together, the texbox same thing!

And the same thing if I want to compare them with each other, for example

if index
= 0 then msgbox ("OK")

It does not work ...

VS 2005 - Localization In Windows Application - Label Which Text Is Merged With Some Variables Or Object Properties

Sep 2, 2010

I've implemented the localization in my windows application with no problem for the label or command button which have a fixed text.

My problem is related to the label which text is merged with some variables or object properties.

E.g.: vb label1.text = "There are " & myDataGridView.Rows.Count.ToString() & " items"

So, how can I set (if it's possible) the localization for these labels? I've this kind of assignment in modules and not in the form. It's possible to set a resources file also for modules?

VS 2008 - Take A String Of Variables With A Common Delimiter And Break It All Back Out Into Separate Variables

[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.

Define Some Global Variables Of A Class - Variables Occupy Memory?

Mar 23, 2012

I 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.)

Multithreading: Reading/setting Variables, And Passing Variables?

Mar 8, 2011

Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.

Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?

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.

Save As BMP / JPG Or PNG In Paint Application?

Jul 4, 2009

I've used this example to create a paint application in vb express 2008, however the example can only open and save .pic files! How can I make it so that my application can open and save a commonly used image type, such as bmp, jpeg or png? I would imagine it can't be that hard, just saving what has been drawn in the picturebox into an image file, or loading an image into the picturebox.

I have tried to make a load event by using some simple code I've made:
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
PictureBox1.Image = Image.FromFile(OpenFileDialog1.FileName)
If Not (PictureBox1.Image Is Nothing) Then
m_Picture = Nothing
PictureBox1.Invalidate()
[Code] .....

When I simply delete this section of code, pictures open fine however of course then I cannot draw, which defeats the purpose of my application. So how can I open and save images with my paint app?
