VS 2008 Saving And Loading Values That Are Entered By The User
Nov 13, 2009
The problem is this: I have two forms. One form and the other form do mathematical calculations. I want to save the values that the user inputs, so when the user quits the program and then starts it up again the values are still there. But when I open up the program, start typing in values, then calculate them, hit quit. Try to open up the program again, its giving me a message that the input file is invalid. When I click ok, the program doesn't crash, continues. But the values are not there at all. The other form I put exactly the same code, just changed the variables and it doesn't want to save the values at all! I wrote this code for saving and loading the values:

I have created a small program that performs various calculations with data entered by the user. I need to be able to save the entered values and the results on the system running the program and be able to open it at anytime in the future and have the values and results displayed in the correct text boxes. I am currently reading up on some tutorials but I was just curious as to how I can send all my data in Visual Basic to my database in Microsoft Access?

Ok, as you can see I am totaly new with Visual Basic. I have learned all those loops, if&else statements, byval, byref and etc. But now, I want to create this kind of application. I have 3 textboxes. One will contain URL, second username, and last password. There is a listbox also and a button. I want when user add a values inside textboxes , that values go to listbox as one variable and then save those settings for user so when he start up application again there are saved variables inside listbox. I just dont know how to do that.

I have been struggling with getting FormViews to work the way Microsoft expects me to for about a day and have figure a bunch of great stuff out.
I can catch e.Exception and e.ReturnValue in the ObjectDataSource.Inserting Event Handler and I can even cheat and check other properties of the Object in the ObjectDataSource.ObjectDisposing by checking the e.ObjectInstance ... and I even learned that FormView's Inserting Handler Runs AFTER the ObjectDisposing Handler so If there is a problem found I still have time to react to it and st the e.KeepInInsertMode to true on the FormView.
My problem is, it seems that the values entered by the user into the Insert form are cleared regardless.
So, How do I Prevent a FormView from clearing after it's Insert Method has fired?
(Using ASP.NET + VB)
I don't think posting my code here will really do much good and i would have to modify it to trim out confidential business logic stuff... so I'll skip it for now.
edit:
I have found a temporary and admittedly terribly cludgy solution (in case no one ever finds a REAL solution to the problem).
I have a page variable defined as:
Dim eInsertArgs As FormViewInsertedEventArgs
And then I do the following in my ItemInserted handler
If boolInsertErrorOccurred = False Then
e.KeepInInsertMode = True
eInsertArgs = e
[Code].....
The effect of this is that I am setting the values BACK to the submitted values AFTER ASP.NET binds the FormView to the default (blank) Template.

I'm looking for a library for Autocomplete support in text controls which remembers all previous entries of the user and provide auto-complete support for it.For example for "recent files" I use [URL] and it works great. Do you know something like that for this purpose?
UPDATE : This is a .NET Winforms application and I'm using normal Text Control.

I'm making a log for my application.I have made the log and it works.I use the streamreader and the streamwriter to save and load the data. I thought that it would be more organized to have columns inside the log.The problem is how will i save the information to the text file and load it up again so that it could organize itself again. The code that i used to make the columns.
log.Columns.Add("Task performed ", CInt((log.Width - 4) * 0.3), HorizontalAlignment.Left)
log.Columns.Add("Time and date", CInt((log.Width - 4) * 0.2), HorizontalAlignment.Left)
log.Columns.Add(" Amount of detected files(s)", CInt((log.Width - 4) * 0.2), HorizontalAlignment.Left)
log.Columns.Add(" App version", CInt((log.Width - 4) * 0.4), HorizontalAlignment.Left)
The code that i use to add the information to the log.

visual basic 2008
I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)

working with dates has always been a tricky part so let me show you how I handle dates in my application and please could you show how do you handle dates and also feel free to criticise. Normally I would create out a system to be able to save and then load a date note I am using a varchar(50) on my SQL Server db rather than datetime but I understand this is wrong, that's why I am looking for a decent way to work the dates out. My system has worked for me fine so far but if I would have to sort the dates ascending or descending I think I would get into trouble because it is saved as text.

I have a Form1 with TextBox1 and Button1.
Here is what I'm trying to do: When Button1 is clicked, I want an Excel file created and saved into a default folder (the user does not choose the folder...code for Button1_Click will choose the folder), and the file name will be the text that the user enters into TextBox1.

I have a simple windows form application (I'm working in Visual Basic Express 2008).
There are some forms that have simple text boxes. When somebody wants to edit something in this boxes he pushes edit button and then they are enabled. I insert some text and when I save this text is saved for good.
When I reopen the application this text is there like I want it to be. Just for information, this text is always the same in one text box, until I change it (me or some other user) - so I think there is no need for databases. For my needs this is ok because I don't need to change this data often. This is code in Form load event (for calling back the data)

I need to save some string settings at runtime and read them back. They will need to be changed at anytime during runtime also. The examples I have found says they are obsolete for vs2008. how to save and read some string settings? I found alot for the application settings that to me are ones you set once for the app like in an asp.net site. I need to change these anytime like you would in a registry.

What is the correct way to handle saving user control settings on form close. I have a tabcontrol that a user can add tabpages during runtime. The user control has a few controls (listbox,combobox,textbox) How can I save the created tabpages and the data in each control in the usercontrol? Below is how I am calling my usercontrol
Code
Public Class TabPageEx
Inherits System.Windows.Forms.TabPage
[code]....
I seem to be a little lost as most documentation seems to suggest that I can not save usercontrol settings in the app.config. I have played around with the solution expl. settings tab without much success. But, then again I may be going about it all wrong. So, I am looking for a little direction on the best way to handle this on form close.

I just need to know how to set up this array within the program to allow 10 values to be entered then later be shown into separate labels as a largest and smallest value.Create an application that lets the user enter 10 values into an array. The application should display the largest and smallest values stored in the array. Figure 8-45 shows an example of the application's form after all 10 values have been entered, with the largest and smallest values displayed.The form basically shows a large label box where your values will show up. Then two regular labels next to the boxed label that determines the largest and smallest values. There are four buttons, a clear, exit, Display Min & Max, and Input Values.I have the actual program layout already made and the initial buttons already declared, being the exit and clear buttons. I just need to know how to setup the array's for the other two buttons.

I'm looking to work on a project at work and I'm preparing to do my home screen of my program and I'm stuck on how to prep for all of this. I want to be able to save projects (and its not just one form that will be saved, 26 future forms to be exact), load projects, create new projects and view available projects to be selected from in the home screen. Really a very standard home screen when concerning professional programming. I'm not quite sure how to go about this or when looking ahead what might be a best practice. I haven't worked with databases, so my knowledge is limited.

Using the Microsoft VB 2008 Express program, I'm making a SWd20 character sheet (D&D) to be distributed to a few friends. It's a program where the user can figure out stats, species, class, etc without having to make any calculations him/herself.. but this will all be in vain without saving it..
So I'd love to know how I could make it so the user can save and load the entire file(including buttons, labels, text boxes, menu strips, possibly multiple forms, etc) on his/her own computer.. Is this possible, and if so, how can I go about this?
I've already searched through and found lots on saving text in the files to .txt files, but that doesn't cover everything I need
