I have a form with a group of text/cbo boxes, and two listview controls. I would like to save these textboxes and listviews into a single xml doc with a schema like:
<MyDataFile>
<MyTextboxes>
<TxtBox1>Some Data</TxtBox1>
<TxtBox2>Some Data</TxtBox2>

and i think I can figure out how to do the text boxes, but how to I write them all into a single <MyDataFile> document root xml file?
I have a Windows form I would like to save the Ovals I created while running the form for use and review later I have been trying the SaveFileDialog but have not figured how to get my data out to the file that is created. I have read about using datatable but there again I'm working with that but need to find how to load all my Oval parameters into the table so I can recreate the current look of the form.
View 4 RepliesI have created a form, that calculates Hotels billing, with one box I can input Number of nights a customer stayed which is £32.50 a night per room and the other box £4.50 for breakfast, there is a deposit of £25.00 which gets deducted upon departure. I have created this form with success along with a clear button But here is the tricky part- I want to create a total button which will display a summary information about the bills paid on that day regardless of how long they have stayed and how many breakfasts consumed. this should include, the total number of bills paid, the total number of nights paid for, the number of breakfasts paid for, the total amount of all the bills added together including the deposit.

I have been using an Access Database with no problems, using a form (with a sub-form) to input all of the data. Recently the data on the sub-form is not saving to the tables/reports. I enter the data, save and close the form and re-open the record and it is not there. Previously I have been able to save all data using the form and have not altered the form.
View 3 RepliesI am working on developing a program that needs to keep the data of radiobuttons, textboxes, comboboxes, etc. and it needs to be able to save several files(one for each different user). I found a quick solution from a forum, but it will only save the data from a textbox, or a tabpage. The solution that i have came up with, is to use the data, put it into a textbox, to save,then when it opens the file, it will use the data and put it back into the controls. (EX.)
If
TextBox30.Text =
"Full"
Then

This does work but it does reduce some flexibility, and takes alot more programming than what is needed. I am looking for a simple way to save the data, and retrieve it.
Alright I have a settings form and when the user checks checkbox. When they exit out of the form that whole form will save in the app.
View 3 RepliesI created a form with 4 textboxes, one date picker, time and combobox. Now the problem I have is that I want to save all the values in these boxes in a folder which depends on what is selected in the combobox.
Source:
vb.net
Private Sub ListBox1_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub

The idea is that if I select 3 in the combobox, the files has to be saved in the folder 3. This folder is located on a server located in the LAN.

What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

View 1 RepliesI'm working on a project which are generating some data from my VB.NET software and I wish to save those data into sql server. But my concerns is the speed of saving and the large amount of data. For every 0.5s, one set of data will be generated and the process will keep running for about 8 hours, so at the end of 8 hours, roughly there will be 60,000 set of data generated.May i know what is the best option/method of saving the data into the sql server in not hanging up my software and also keeping the pace with the speed of 0.5s data being generated?
- Speed of 0.5s. I have to maintained for every 0.5s, one data must be generated. Cannot delay too much.
- I can afford delay in the sql database, meant the data might not be necessary close to real time.
I have a small application that consist of five tables. The main table is called inventory. I have four tables linked to the Inventory table

I can go in and enter data, create a new record and add more data and then click Save - nothing happens. I can cycle through the records and they will show. However when I exit and reenter the program (stop/start debugging) done of my new data is displayed.
I am thinking the problem has to be with the four tables connected to the main table via the ID's. Although a record is not being added to these subtables. So, I am not sure what's going on.
I have provided the code below. Please take a look and give me some direction.

I have a very simple DataSet linked to a ListBox. I need the User to be able to add Data and have used the following code (in a ToolStrip command button):
Dim newFileRow As DataRow = Database1DataSet.Tables("tbl_Files").NewRow()
newFileRow("File Name") = fleName
newFileRow("File Path") = flePath
[Code]....
This seems to work ok - the new Data immediately appears in the ListBox. However, as soon as I close the form all of the Data in the DataSet is lost.

What I have is a program that is going to monitor and store different stats about different email servers. The basic layout of the main form is a datagridview. Now this program does not need to store the information into a database as it is only going to run on one machine which is why I did not bind the datagridview to a dataset. Maybe using a datagridview is not the way I need to go but researching around the only other option would be to save the data to XML. However since the table does contain hidden fields with authentication credentials, I am a little bit hesitant about doing so.

I'm using VS2008 with SQL Express 2010. I've a one to many relationship and a form with these two tables on. I'm using the BindingNavigator toolbar and when I press the + button, a new record appears. However, I have to press the save button and save the parent data (which is in Details view) before I can add any data to the child table (which is in a DataGridView). Once I've clicked save, then I can add child data no problem, then I click save again and all my data is saved.
Is there any way to save all the data at once? If not what is the best practice for telling the user when to save? Should I make the child data grids invisible until the user clicks save?
does anyone know a simple code that would save data in zip format ?
View 3 RepliesI am making a simple program in Visual Studio 2010.My program connects to a MySQL 5.5.8 database running on my computer through XXAMP. I have used the Connector/Net 6.3.7 for MySQL to allow me to do this.
This is the local information for the MySQL server:
Server: 127.0.0.1
Port: 3306 (default)
Username: root
Password: admin
I have successfully created a Data Source for this server. The DataSet is called 'testdbDataSet'.
This is what my program looks like:I do not want to use the navigation bar that Visual Studio gives me at the top. Instead, I want to use the buttons shown below the input fields. The btnAdd button I believe should clear the two fields. It is currently working fine. I want the btnSave button to save the stored values of the two input fields to the database. I do not know how to do this.
I am currently having a few issues saving new information to a dataset. I could update the set, but on exiting and reopening the data all updates were gone. I found a few tips online but now get error messages when running the update command. This is how the code looks at present.
