VS 2010 Save Into Temp Data A User Made Class?
Jun 4, 2010
Is it possible to save into temp data a user made class? I have a class with many structures and each structure contains variables and im trying to add to my program a way to save the data of that class object with its structures and everything is that possible? I tried manually making some sort of save but its taking too long and proving way too hard for me. Is there a way to just convert it into some general object format and save the object? Is that possible can you just save undefined objects without having to create a format manually for that object?

I'm trying to figure out a way to sort the entries of a listbox... but in a different way instead of the obvious one (sorted property). First of all, I need to explain how the items are populated at first:

I need my application, save the data for each user ... In short, whenever you start the program, it will do a check of these data.I had thought to save the data in an external XML file, but if this file will be deleted? Or use the registry and save the data using a registry key, as many programs (I think) save the activation (SN) of a program...

I'm making a video editor program and I'm getting kinda stumped at the save portion, I've worked with openfiledialog so I figured save would be sorta the same. What I'm doing is adding files(music,videos, and pics) to a flowlayoutpanel. I just don't know how to save those controls made at runtime, this code is my import code. It's pretty much the same for music, video and pics with the exception being the format and openfiledialog being used:

I'm creating a program and i want it to secretly save when the user clicks on save.
In other words, i have made it so that it saves twice. Once for the user to read (like a fancy copy) and another that the program uses to open up the form.
Currently when pushed, 2 save dialog boxes come up after each other. I don't want this to happen. I want 1 to come up (the user friendly, fancy version) which is the easy part, but i also want the other 1 to save automatically and secretly without asking the user to set the destination.

in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.
For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.

Am trying to copy contents of file temp.fxl to temp.seq. I want them to look exactly them. I don't want to copy the file though. I use the following code
Dim fs As New FileStream("c:\fxlate\output\temp.fxl", FileMode.Open, FileAccess.Read)
Dim s As New StreamReader(fs)
[Code].....
With such simple code, the last line in temp.seq is truncated as attached and the size of the file is smaller than temp.fxl. See attached files. What do I need to do on the above code. Is VB.NET failing to write 1024 characters on one line.

My problem is when I try to run the program: No errors of syntax.
What I must do? I need to right click in solution explorer add new item->add->class and copy here this code?
After I write the code I chose from the vb menu: Build->Build Solution_name
Before writing the code I choose File->New->and selected class library then save all to save as a project.
Or class library is only a dll file that runs with a windows forms application. (that is added after i write the code for write library).

I have a question. I have a asp site that keeps track of inventory. I currently have it as to where any updates to the inventory, an email is sent with the new changes. How can I get it to send the old changes and the new changes. I know I will need to somehow temp store the old values to use them in the email, but I can't figure out how to do it. I don't want to store them in an actual database table.

I have created a program in Visual basic 2010, the program contains many different objects e.g. datagridview, textbox, buttons, graphs etc, which can all be modified by the user. The user can also select a file using 'SaveFileDialog'.
Is there a way to save all the properties associated with each object to this file and later load the program back to exactly the same state it was saved in, after the user has selected saved file using 'LoadFileDialog'? Preferably in binary.
I can do this the hard way in ASC11 format by interrogating objects user editable properties and saving them. I would rather not use this method as it will require a lot of code and any future program changes will require a lot of extra work.

how to create a panel full of items (textboxes, buttons, labels, ...) and save it as a class with all it's properties so I can create it and place as object on other panel. My goal is to create an application with menu on the side and change workspace (the part on the rest of the form) between 3 or more possible different "workspaces" (made by the classes).

In my Tools/Options box under Projects and Solutions/Build and Run, I have selected: Before building: to "Don't save any Changes."However, after making changes to a form, I would like to run it without saving, but I get a message that forces me to save, unless it runs the version of the program before the changes were made.The VB 2005 edition works the way I want it to allow testing without saving, but VB2008 does not allow this.Is there any way I can change this behavior?

I would like to commit the data put in a checkedlistbox to the user.config. I have found a way to commit them to my.settings but no matter what Save() method I call, it does not commit the new data (that is not bound to a control, through the propertybindings) to the user.config, either immediately or when I shutdown the application. Which means, when I loop through the settings when the application starts back up, the data is not there to be added back to the checkedlistbox. I have put save methods in the formclosing events as well as when the data is created in the my.settings. using my.mysettings, my.settings and my.settings.default. Thank you in advance for your input.
This first method is a called when a button is pushed. it checks the text and then calls the next method (AddProperty) which should add the property to my.settings and save it to user.config, but my understanding is that it is not written to the file till the applicatoin closes.

I have never worked with datagridview before. I need to know how to use it so i can use it in my (calculator) program. I would like to know how to make columns, rows, linking the cells in the table/grid to textboxes so values entered into the textboxes (on the calculator) after pressing save goes straight to the table.

I have made a class that represents people. When I create a new person, it causes an warning saying "Variable 'NewPerson' is used before it has been assigned a value. A null reference exception could result at runtime"
HOW I have tried to fix it.
I have tried adding value to many of the properties, but it still says that.
WHAT it is like.
It is almost like I have a string with a value of null.

I am in the process of migrating from VB6 to VB 2008. In a pixel grid system I have thousands of cells with about 15 properties each. In VB6 I employed the user-defined datatype "udtCell()" as my array structure. Is this still a good approach - or should I perhaps make Cell a class?

How do you save settings for a DataGridView? I'm making a game, and I want the user to be able to save their settings in a datagridview, and have it opened when he/she looks at the records form again.
I know this is what you do with a textbox, lets say:
My.Settings.Username = TextBox1.Text
My.Settings.Save()
But how would do that with a DataGrid View?
