How can i make variables stay true even after i close my program so on next run there still true?Heres the Code i am using to set the variable (if it helps) :
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Activated As Boolean
If Activated = True Then
[code]....
BTW this is to check if the product has been activated or not.
I'm using the 2D graphics engine of Visual Basic. The graphics are fine for my purposes, however they erase when they move out of sight.I was looking at the System.Drawing.Graphics properties, and came across a save funtion, however that did not prevent the erasing.How do I prevent this from happening?
View 3 RepliesI have created a project to update my applications; it is simply a form, with a progressbar and some other fancy stuff, which will check for updates via FtpWebRequest and download files if necessary. I have code it so that in order to use it for other applications I only need to change the ftp folder address and the .exe name for the main application to be started.
So the question is. Is there a way i can put that project in a dll so that I can simply pass it to my partners without having to pass the source and obviously have some way to change the ftp folder address and the .exe name like some kind of properties�.

View 6 RepliesLast 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.

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 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?).

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 ?

Then when the user presses save, it will take all the shots, import the cursor in each one and then create an AVI using each of the frames that were initially shot. Another better way would be to take a screenshot with the cursor in it, if thats possible.

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.
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?]
View 5 RepliesI 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.

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.

so i have a quite huge program. but lets say i have one label. and i want to save that. i have the code and everything for saving the text of the label. now i want to assign ctrl+s to automatically save the labels text once pressed instead of going through a menu to choose save.this is like a regular texteditor where u press ctrl+s and it saves.
ive used this

My question is simple (the answer may not be...), What I am looking for is a way to save a file as an encrypted file (so know one can open it except in visual basic or a way to save it with a unique ending that only visual basic will recognize. I will also need to know of a way to open or load the file to.
This is going to be used in a game I am working on (and yes...I know visual basic isn't really meant for games, but it is coming together pretty well). I was originally going to have it save as a text file, but then everyone could open, read it and even change there stats. That is what this file will contain, the stats for their character, and when they load it, it will place the values into the correct spot.
I am a partial beginner or intermediate coder, I can understand code, I just don't know all there is, like saving and loading, and this is probably a little harder.
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 2 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'm a huge music person (got my own lil record thing going) but I'm wanting to design a program that would make music in my way. I have a decent amount of background knowlege of Visual Basic and Java I'm just wondering how could I execute this whole project. The Project is making a MPC Sampler. MPC is a drum machine; a machine with buttons that once you press it that it will play a sound from a drum (ex: snare, kick, tom, ect.) . So I would want to make some pads on my program that each have their own sound. Total of 16 pads. Which the design wouldn't be hard to make nor would the functionality of it having the play back sound (in my opinoin it wouldn't be hard atleast). But the thing is I wanna map out these pads to number keys on the number pad or keyboard. I'm not so sure how to do that. But that's all the easy stuff...
Also finding information is making a sound directory. What I mean by this is that I want to make a User Interface that will open up a file directory of sounds and the user can select what "kick" or "snare" sound he may want for the kick or snare pad. I don't know how to do that or even know what to search; neverless I don't know if this whole project idea is a good idea for Visual Basic or another programing language.
Also LATER ON I am wanting to add a record and export function that alows users to..well...record and export their beat or instrumental ha. That doesn't seem too too complex (mainly due to the fact that all it needs to do is record the users key strokes and then show them and play the sounds, but obviously it would get more complex than that.)
Here is an image of one of many MPCs but one with a directory - [URL]
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.
