VS 2010 : Exporting Database File From Friend's PC?
Jul 13, 2011
I made a program for my friend, a patient database program using VS 2010. I'm worried if my program messes up she loses all the records. Here's what I remembered doing. Maybe you guys can identify how I can fix this or you can give ideas on how to avoid the same mistake.
1. I used Visual Studio
2. I made a VB Windows Forms Application
3. I made a Service-Based Database called Database1.mdf which is a Dataset Model
4. I chose save connection string to Database1ConnectionString
[code]....
She was glad with how simple it was cause I made it with Visual Studio. Now I dunno how to export the database file from her computer/copy of program to make a backup. I dunno what to do.I know I didn't ask for anything in return but if the program messes up I'd feel bad. 1k+ records already jesus christ and the program has like 74 columns/textboxes.
I have done a small app using vs 2010 with an access database. Initially what my friend asked for, was an app, running on one computer. So local access database was a good choice, i thought.
The app is used for collecting data from different enterprises, and different workers in this enterprises. My friend asks me now: �what if two people are using the app on their computers, collecting data in the same place from different workers. Can I, at the end of the day, export data from one computer to another, so that i have the full information in one computer, in one database?
My answer is that this was not the purpose of the app. Probably we should have looked, instead of a local database, for a web app using a centralized mysql database.
But since that is not the case, and the app is almost finished, my question is: can you do it? Can you partially export some records from different tables, and import them later, so you have the complete actualized database in one app?
I have to export the data from the database to .txt file, I have the code below that does export it to .txt file but I'm having problems with this code because the data that I'm exporting is about 5 000000 records, it is quite slow and sometimes the pc can't handle it and stops the exporting.
Dim saveFile As New SaveFileDialog If saveFile.ShowDialog = Windows.Forms.DialogResult.OK Then command = New SqlCommand
A friend at work is trying to write a piece of database software for an HND project and when adding his database file, he gets the below error message. I'm too much of a greenhorn to know what it means, can anyone make sense of it?
I've been reading about access modifiers in VB.Net lately, and there is something that I can't really understand: How do elements in a Class (or Module) inherit the modifiers of their enclosing block?For example, suppose you have a Friend class Bla in an assembly, with a public method Foo:
Friend Class Bla Public Sub Foo (...) End Class
Does it behave differently than when Foo is set to Friend?
I have vb.net application which is using Vistadb with following connection string. I am able to export data to excel also. But after exporting to report different than to application directory, program crashes and says that database not found in exported directory. i believe that there is something wrong in connection string but I van't find. [cpde]...
I have an access database (made by other application) that I need to read it. The problem I have is that the tables I need to read do not have the read permission; the access permission is set to "Share Deny Write"; though I can open the database in MS Access and export the table to another mdb where I can read it. Is there any way to automate this, or to set read permission on the database using VB.net? Is there any other way to get the info from table not having the read permission?
I am trying to export an excel file directory into an Oracle table as opposed to looping through the range and executing a lot of insert statements. I would think that there are better ways to accomplish this in .NET but I can't seem to find any other answer besides convert excel to csv & load it using Sql Loader or External Table. Does anyone know a cleaner & more efficient way that looping through the ranges creating & executing insert statements?
I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.
What I want to do is then export this data from the datagrid into a file, preferably excel.
I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.
Im doing a project with .Net 4.0, Visual Studio 2010 and Visual Basic .Net.I needed to add a Chart (the new one included by default in .Net 4.0) that represents temperatures evolving with time, so I added the drawing points in the elapsed event of the timer every second.The graph is doing somewhat ok, but I need another functionality, and this is, every time I stop the timer, save the graph in an excel (.XLS or .XLSX) file. As by default the chart provides with a collection of the type "System.Windows.Forms.DataVisualization.Charting.DataPointCollection", I would like to know if there is a way to create an xml and put the info of those collections in the excel file.I have looked around but I didn't find any similar example, last thing im thinking about is to use an iterative way to manually write in the excel file, but maybe its too much time consuming as the iteration will be of several thousands seconds.
I have the following code: Public Class Payrollfinal Private Sub Payrollfinal_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub Private Sub payrollsubmitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles payrollsubmitButton.Click [Code] .....
And when two things happen when I try to use this code (which I modified after finding it on another site) 1. Intellisense tells me that MyDataSet is not defined. 2. When I define MyDataSet as Dim MyDataSet as New Dataset Intellisense tells me that I'm told that AppendText is not part of String.
I have a form that I'm writing that will run a stored procedure, present data from that stored procedure in a datagridview and then allow users to export that data to a csv file. I found the following code:
Code: Imports System.Data.SqlClient Public Class Payrollfinal Private Sub Payrollfinal_Load(ByVal sender As System.Object, ByVal e As
End Class and what intellisense is telling me is that MyDataSet is not declared (I took the code for this portion from another site and modified it to suite my needs.) I tried adding the declaration Code: Dim MyDataSet As Dataset but when I added that, where ever there is a .AppendText statement, I'm told that AppendText is not part of String.
Currently I am building an application that will do Data Validation on an Excel Spreadsheet.The application will allow a user to load an Excel Spreadsheet in and runs checks on the data. The application needs to export the spreadsheet as a pipe delimited file with all of the fields separated by the character.Currently I have written an Excel Macro that will export it as a Text File then delimit it and save the text file as a .ps1 file. I cant seem to figure out how to write this same code in VB instead of VBA.I am currently using Visual Studio 2010.Here is the code for my Macros that work fine but I need it in the application and not on the spreadsheet.
I have a a DGV with the following fields: FirstName LastName Address Job StaffNum Nationality DOB Notes Picture FileName
Now my DGV has records in it and I try to export it to Excel File. Now it exports the the Column Names above but none of the records. My code is below. Dim fs As New IO.StreamWriter("C:exported.xls", False) fs.WriteLine("<?xml version=""1.0""?>") fs.WriteLine("<?mso-application progid=""Excel.Sheet""?>") fs.WriteLine("<ss:Workbook xmlns:ss=""urn:schemas-microsoft-com:office:spreadsheet"">") fs.WriteLine("<ss:Styles>") [Code] .....
I got this code from the MSDN forums from a link someone posted. They said they changed IntCol and it worked to incoude the records as well but I cant figure it out. When I hit Export it does prom,pt me to save the file and saves the Names above to excel sheet but none of the records.
this is my problem: i've some data in an access database, i collect this data from the table and when i try to record the data in the text file, with the fields separated with a "!",the registration fails, better, doesn't register all the datas that are in the table.This is the
Dim tw As TextWriter = File.AppendText(Application.StartupPath & "DStampa.csv") Dim objDataTable As DataTable Dim TotaleDatiStampa As String = ""
I am trying to export text from the following textboxes:textbox1.textextbox2.text To a standard text file (notepad) to save the data. I want to be able to click a button, and what I type in the 2 textboxes save to this file, then I want to be able to add more values from textbox1 and textbox2 to then add to my textfile, so that I have several strings stored in the textfile.
I have a field that needs to be 10byts long. However, if the number does not use all 10 bytes, then it will need to have zeroes in front of it.say you have a Check number of 12345, well in the text file it would need to show up as : 0000012345..This is the code I'm currently using but when I open the text the other 5 remaining bytes are just spaces. [code]
i have my program and it does what i need it to do but when i export the contents of the text file it does not show the new line characters. it displays it in the text file like this all on one line
I can export my radgrid to an excel file but I want to add some more info into the sheet.If it is possible, I would appreciate for a tutorial/sample code for doing a custom excel file generation.
I'm brand new to this forum. i have a question. i wrote some software a while back and now have a few new features I need to implement. this software currently makes use of "application settings" to store all of it's settings. Which works just fine.
I have a client that has about 40 users. He wants to be able to share his settings (that he set up in his copy of the software) with all of users. Preferably by distributing a copy of a config file that they would be able to import into there software.
I want to export data from a DataGridView to a CSV/text file. I then also want to be able to load that same CSV/text file and populate that same DataGridView at a later point in time. My information is loaded into columns in the DataGridView. That is, I am not using rows to represent records, I am using columns. As such, I need to load all the data in each column and export this, by column to the CSV/Text file. Likewise, when I load the control from the CSV/text file, I need to load each column with this information.How do you export/import from/to a DataGridView controlHow do you organize the data in the CSV/File
In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < b>Column Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?
