Saving Data Which Would Need To Be Updated Every Time The User Exits The Program

Aug 21, 2011

I want to work on a project I have in mind and this envolves saving data which would need to be updated every time the user exits the program. I suppose I need to know how to save a file to a blank text document, and how to get the application to read the information when it is called for. I believe I need to set delimiters or such, the helpfile is useful, but limited and some information is not listed at all.

Saving Information So Program Remembers Next Time User Signs In

Feb 25, 2010

i want the user to login, and the first thing is, having the text document for that(if theres a safer way to do it, let me know) then it goes to the weekly sales page, but theres also the goals for the sales, which rarely change, but if they do i would like them to be able to change them, then next page is the list of the workers, and if they need to i would like them to be able to add workers. so my question is: is there anyway that maybe i could save both the goals, and the workers in the text document, and when they need to change it/add workers it will save it in the text document and the next time they sign in the changes will be permanent? also is there a way to delete the user once they have been created, other than going into the txt document and deleting it.

Acrobat Hangs After User Manually Exits Program

Jun 4, 2012

I'm currently having an issue with VB.Net and Adobe Acrobat. The issue comes from exiting Acrobat but the Windows Taskbar still states that there is an Acrobat.exe process open. I have tried using Marshal.ReleaseComObject(), but it still hangs there. I do not want to have to rely on the "End Process" option on the Task bar in order to remove it.

Below is a snippet of the code that I am try to using:
Try
'Tries To Close Acrobat Application
acrobatApp.Exit()
System.Runtime.InteropServices.Marshal.ReleaseComObject(javaScriptObj)
[Code] .....

Although I am not sure if this could be a problem - I run a javascript saveAs script on the Acrobat side in order to make a copy of the file. This also could be a reason why it is hanging, but I ruled it out based on basic knowledge of saving files and exiting from other Acrobat/Microsoft Programs. Acrobat only closes when my application ends. (Currently) I am trying to make it consider the case if a user manually closes the Acrobat application.

Do Data Validation When The User Exits A Control

Jan 31, 2012

What is the best method to do data validation? I want to do data validation when the user exits a control so that he gets immediate feedback. I can use the Validating event or the Leave event for that. The problem is, that if the user doesn't know the right answer, and just wants to click the cancel button and leave the form completely, it won't let him. It continues to give him an error message until he completely deletes his answer. Very frustrating. Does anyone have a good method for doing this?

Allows A User To Select A Program To Run At A Certain Time For A Specific Amount Of Time All Choosen By The User

Jul 1, 2010

I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.

Saving The Screenshot - Program Where The User Fills Out Info

Nov 17, 2009

I'm making a program where the user fills out info, then they click one button and the program takes a screenshot of the form, then they click another button and the screenshot gets saved. I'm having a couple problems with my code though. For one, I'm trying to make the screenshot go to an invisible picturebox to make saving easier, but I cant figure out how to make the image go to the picturebox. The other problem is that I want it to automatically save without showing the dialog, but so far, it won't save.

Datadase Not Saving Updated Information In VB Express 2010?

Dec 1, 2010

I have run into a problem with saving to database when running the program I am making.

I have an mdf file called prices.mdf and have set the "copy to output directory" to copy if newer setting and set this for the ldf file build action is set to content.. should it be compile or a different setting??

I access this database thru a dataset called pricelist dataset and when the program runs and you go to forms to update the prices, each form has a datagrid with the toolbar and the save icon. Mostly I followed tutorials to help me put it together.

When you run the change price menu for each part of the database, they appear to save each time u re run the program. But once you close down vb2010 and reopen it a day or so later and rerun, the new prices are gone and the old prices are being used.

I thought changing the setting on the mdf file to copy if newer is the usual fix for this, but as I said I have already got it set to copy if newer.

I can't figure out how to track what the dataset is accessing to make sure it is going to that database, or if i have made some sort of other database that it is accessing instead as well as the mdf database.

when I look at the dataset and the column entries for each part of the prices database, as to whether i need to check the dataset itself, or the forms the datagrids are on with the toolbar save icon, or whether there is another place to check to see if it needs to be changed to something like change if newer.

Obviously the program is working and doing the changes, but not storing them in the right place, so I am losing the changes once i shut down my project and reopen it.
also I have looked at the file propertiesand made sure they all set to copy if newer PricelistDataSet.xsd, pricelistdataset.designer.vb, and also the pricelist dataset.vb, xcs and xss ones are all set to copy if newer when I look in the solution explorer.butsome of the build part is set to compile on some and none for others As I am not experienced with VB 2010 or databases I am not sure how to track it down

Update: Just looked under each of the forms the data grids are on. and see the copy to output directorys on these are set to do not copy for each of the designer.vb, vb and resx. I am bit hesitant to change these without getting some advice from more experienced people if the forms also need to be set up to copy if newer.

This is what is shown in the coding on one of the forms if u double click on the save icon in toolbar

Private Sub TimberpricesBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TimberpricesBindingNavigatorSaveItem.Click

[Code]....

It was coded by dragging the things from the dataset as a datagrid onto the form. It is not coding I worked out, in case more needs to be added to the coding

VS 2008 - Program Starts And Exits Immediately

Dec 6, 2010

I copied a project I wrote on my XP machine to my other computer with Windows 7 64-bit. When I run it through VS2008 it exits immediately. It does not run a single line of code. The exit code is 0. I need to post what else it says. But I did find a posting about this saying the path to the temp files may be wrong for it but he did not know how to change this. If I create a new peoject and put a command button on it, the program runs. So I was wondering if it is something like the temp files or something else. The machine runs a compiled .exe of the program from the XP machone when installed on the Windows 7 machine. So I do not think it is the program not being compatible.

Program First Open And Saving Data When Program Is Closed?

Nov 19, 2011

I am currently working on a menu driven console program that so far has 4 menu options of checking internet connection, decrypting/encrypting a message, calculator, and a logout, and i am wondering about a few current things.

1. How do i make it to where, when a program starts for the first time, it asks for a user to enter in his data, like signing up for a site for the first time?

2. How do i make it to where the program will save the data entered, and does not delete when the user closed the program.

3. How can i make it to where when a user signs in, his/her data is read correctly? Like an array search for a multidimensional array.For my "New user" sign data i created a function...

Function createNewUser() As String()
Dim name As String
Dim userName As String[code]...

Simplest Method Of Saving User Input Data?

Jun 9, 2010

So far i have a really basic form application that allows a user to enter some information and does a small calculation, displaying all of the information gathered on the final form.

Im looking to try to save this information but have no idea where to start,im trying to just take whatever is in my text field and put it in a table row. I created a one table database in Access and linked it to the form with a button to try and save it.

I thought it would be as simple as tablename.rowname = textbox.text or something but apparently not and all ive ended up with so far is this:

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Me.Validate()
Me.TblCustomerBindingSource.EndEdit()
Me.TblCustomertableadaptor.Update(Me.DatabaseDataSet.tblCustomer)
End Sub

I dont even think im close, ive just been fiddling with the predefined code in Visual Studio, trying import ect but the button just doesnt seem to do anything.

Wpf - Saving User Config Data To XML And Relative URI Error

Mar 4, 2010

I am working on a program where some application config info is stored in a Userconfig.xml file. I am loading the file as an XMLDataProvider in the XAML via relative URI:

<XmlDataProvider x:Name="UserConfigDataSource" x:Key="UserConfigDataSource" Source="UserConfig.xml" d:IsDataSource="True"/>

I have a number of items throughout bound to elements in the document and an event handler that saves to the XMLDataProvider:

Private Sub SaveConfig(ByVal sender as Object, ByVal e as System.EventArgs)
'TODO: Add event handler implementation here
Dim SavePath As String = UserConfigDataSource.Source.LocalPath.ToString

[Code]....

When this executes I get the error "This operation is not supported for a relative URI". Is there a good way to produce an absolute URI (aside from getting the assembly executing location and trimming the executable filename from the end)? I expected this to be a somewhat simple procedure.

C# - Load The Settings The User Used The Last Time When The Program Starts

Jul 18, 2009

My typical application has a couple of textboxes, checkbuttons, radiobuttons, and so. I always want to load the settings the user used the last time when the program starts, and also want to save the settings as the users clicks "Save settings" or closes the application. When the user attempts to save the settings, I'll have to check each of the controls for input errors (sometimes they have to have a max length, other times only caps, other times other things, there isn't a rule for them all, everytime it'll be different), and only if everything OK i'll let him save the options. If there is something wrong, no option is saved and my error-control provider will pop up a description of the input type info that should be put in that control.

I've been designing this from scratch for all my projects, but it's being a pain to do it. So I'd thought maybe now was the time to do some library to help me. I thought initially that maybe it'd be a good idea to have all the controls on my form that are going to be part of this save/load process to have an attribute associated with them, something like this [Code]

Saving Data Added In Other Forms In Program To A Single Record?

Apr 16, 2009

I have been working on a project which is used by a company's sale team, to combine all the wanted input data in one place allowing the sales team to show customers, where switching to them could save them money.

Basically what i want is a program which can save single records, which can hold data added in other text boxes, or indeed take the data from the list view boxes which is the intended output. I want to be able to save that data, then be able to Open it up again at a later date, and even modify it.

enabled me to save the three ways to identify a single record, the index number, company name and the date it was added. However I now need a way to save the data entered in my other forms to these single records.

Creating A Program For Which Will Calculate The Time Taken For A User To Make A Number Keystrokes?

Feb 18, 2012

I am creating a program for which will calculate the time taken for a user to make a number keystrokes. I want to start the timer running from the beginning of the first key stroke and end on the final keystroke. Each keystroke has been linked to a label which will change colour according to whether the key has been pressed. When the keystrokes have been finished I want to save this timespan in a field in a database. To test that the timer is running I have made a messagebox which will show the time taken however it is constantly showing zero and the label for the final keystroke is remaining in the keydown colour.

Public Class Form1
Dim dteStart, dteFinish As Date
Dim span As TimeSpan

How do I filter up this validation code through a datagridview and stop the program saving the data? If you need the code for more information, I will add this to the forum.

Write A Program To Request Positive Numbers One At A Time From The User In An Input Dialog Box

May 12, 2009

I'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much

[Code]...

Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.

DB/Reporting :: Updating Client Data Tables When Data Table On Shared Drive Is Updated?

Sep 28, 2009

I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:

1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.

2) A server application does some work on some text files, periodically updating the data table.

I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.

1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?

2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

C# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?

Sep 6, 2009

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).

I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
