Ok, so I've got this Visual Studio 2008 Project I was working with about a year ago perhaps. And this project had a datagrid that was linked to an external database running on a server off the internet. Now, this databinding was all done using Visual Studio 2008's built in features. But how can I now change the binding to a different server, without destroying the project? I've noticed that a lot of the code that Visual Studio creates makes a mess. So manually trying to change the datasource has allways f*cked up the whole project for me.
I'm not all that good with this stuff, that's why I used the built in features of Visual Studio. But I noticed that several things appear, like a binding source, and a dataset. Is it possible to do this? Perhaps even better, making these settings be controlled after the program has been compiled. The way it is now, it's all hard coded after compiling, and that kinda sucks. I remember trying to do this about a year ago, trying to bind these settings to variables stored in settings. But I never got that to work. Just throwing around ideas here
I have version VisualBasic.2010 Express Edition , but this version Does not have the choose Microsoft SQL Server (SqlClient) when open vb.net choose : add new data source and choose database and add connection Does not have the choose Microsoft SQL Server (SqlClient)
When I try to change the datasource of my DataGridView, I am loosing the order of the columns and their type(checkboxes,comboboxes) that i specified on designtime! It's like changing the datasource is generating again the datagridview, why ? and How can I change the datasource without losing these information ? on form load i do something like
Private Sub frmGrid_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim Path as string
I'm using VB.NET 2003 windows application.i'm trying to display Crystal Reports using CrystalReportViewer.
Code i'm using to display "ZTab.rpt" in CrystalReportViewer when Form_Load Code: Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]...
for example: if we are using datasource "work.mdb" for "ZTab.rpt" when form_load. when i hit a button, how come i change the datasource to "Employee.mdb" for "ZTab.rpt" during run time using codes. so when form_load it will display ZTab.rpt with datasource "work.mdb" and when i hit a button, it will display ZTab.rpt with datasource "Employee.mdb".
i'm trying to display Crystal Reports using CrystalReportViewer.
Code i'm using to display "ZTab.rpt" in CrystalReportViewer when Form_Load
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load CrystalReportViewer1.ReportSource = "ZTab.rpt"
[Code].....
so when Form_load, it displays "ZTab.rpt" and when i select one crystal report in combobox and hit button "Run", it displays corresponding crystal report. that works fine.
how can i change the datasource of a report during run time using codes (programming).
for example: if we are using datasource "work.mdb" for "ZTab.rpt" when form_load. when i hit a button, how come i change the datasource to "Employee.mdb" for "ZTab.rpt" during run time using codes. so when form_load it will display ZTab.rpt with datasource "work.mdb" and when i hit a button, it will display ZTab.rpt with datasource "Employee.mdb".
I am working with two seperate SQL statements when user conducts a search on my winforms app.A user can search based on an OrderNumber, OrderDate, ClaimNumber, ClaimDate, CustomerID, CustomerPhone One SQL statement returns the OrderNumber (in case the user searched based on OrderDate), which is used to execute another SQL statement, which returns the details about the order.
The results are populated in a gridview.Once the first statement is executed, I have a DataSource (DataSet). How can I append that datasource to display the fields from the second statement as well, keeping in mind, that the first statement could return multiple records, all of which will need to have the appropriate order details correctly linked.
I am a beginner in vb.net and I need to customize our application based on end user requirement in the office, I need to create Login Box for the Application to protect my database. I have a loguser table in SQL with field on userid, username and a hashed password for everyuser. Now I created a new project in vb.net and I am confused to what to use on the toolbox? First I use the windows forms to create the txtbox, command button and labels, but then I am confused already I can only create local login in my pc windows account, I need the log-in on my database application based on their username and password saved on the tables.
me..ExampleSQL(datainformation):ServerName=Aries, DatabseName=Jupiter, TableName=UserLog, FieldName=Username, Userpassword, Example in VB.net forms I created lblUsername, txtusername, lblpassword, txtpassword and btnLogin.
I have a vb.net project. I have used the GUI and wizard to create a DataSource pointing to a SQL Server Stored Procedure. It works great! However, a new column has been added to the stored procedure.In the GUI if I right click the data source name and refresh, nothing happens.If I right click the stored procedure name and refresh, nothing happens.If I preview data I can see the new column returned.If I choose edit with wizard there is a red exclamation point next to the name of the stored procedure and red X be each column name.
When I hover over the field name it says "Column ABC in the DataSet references a column missing from the Database".When I hover over the stored procedure it says "STORED_PROCEDURE is mapped to STORED_PROCEDURE in the DataSet. Element STORED_PROCEDURE in the DataSet contains columns that do not exist in the Database".I can't figure out how to get the new columnd in the dataset.
I have to change my sql server and need to point all my crystal reports to that new server at runtime, some reports has StoredProcedures embeded inside and those are the problems.[code]....
I have made several changes to the columns in an Access db, such as additional columns, column type changes, etc. how do I now incorporate those changes into my datasource? Do I need to delete the datasource and create it from scratch?
So I have an application which uses MSSQL server as datasource. Is there anyways I can avoid using any database server and use a local file as datasource ?
I normally place all db related work in my databases in SQL Server Express 2005. But in tutorials I have seen, I heard that one needs to re-create referential integrity and relationships and constraints and checks and defaults anew in datasources mapped onto databases. Is this true? What parts of a database are NOT mapped on to datasources?
So based on what is selected in a radiobuttonlist i want the select command to change for my datasource. The problem I'm facing is that if i set the default selected radio button the query will work for that
my radiobuttonlist , user (dropdownlist are all located in an update panel that is not updated after the button is clicked
this my button code
If user.Text = "ALL" Then SqlDataSource22.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE [completed] = 'NO'"
I made an application that was used by one person only, but now my boss told me that this application it'll be used by all company.I made the application with a dataset that have the datasource in a access database that's installed with the application. The user can add, delete and change values in the database, so i had to put the database in a sql server to everyone see the changes.There's someway to change the dataset datasource/connection string?
Let me try to describe my problems in the simplest way: I have combobox1 and combobox2. I hope to achieve two things: Combox1 is bound to list1 (a list of string). When a user selects an item in list1, list2 (a list of string) will be obtained from database and combobox is bound to list2.If user specifies text1 in combobox1 and text2 in combobox2, then these two values will be shown in the comboboxes regardless of the bound lists.
[Code]...
So the results of above code is that goal 1 is achieved, but goal 2 is never achieved. combobox1.selected index is always 0 and combobox2.selected index is always 0 too.
I have a VB.net 2005 application that will use both Access and SQL server databases. I have DSN namesfor both access and sql server database. I used OleDb.OleDbConnection to open the Access database and it works fine. I am trying to make it work with sql server database. Do I have to have to have separate source codes using Sqlclient.SqlConnection and its related name spaces? Can I use odbc.OdbcConnection name space
I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'. ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then IndexOutOfRangeException was unhandled Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.
I have an error ERROR [22018] [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression. and I've been trying to solve this but unfortunately I couldn't get the hack of this error. I'm a newbie in dotNet.
Public Sub LogInContinue(ByVal senter As Object, ByVal e As EventArgs) Dim LibDS As DataSet = New DataSet Dim LibDA As OdbcDataAdapter = New OdbcDataAdapter("SELECT * FROM tblUserAccount WHERE Uname='" & txtUserName.Text & "'", LibConn)
Create a membership database that has fields for title, first name, surname, address, subs renewal date and membership type (active, social, honorary or life). Make an interface that allows a user to display, sort and create records. Consider the use of drop down boxes to aid error free input.
When i add a new datasource i get to "Select database objects" page and then i get an error message. "Could not load "Microsoft.etc"", im using an access database with pre-created fields.
I have a DetailsView that looks just about perfect. The only thing is, there is one field that actually gets its information from another table. It is an ID field that is linked to another table in the database and I was hoping that there was some way to get that one field in the DetailsView to pull the information from the other table.
Is there a way to maybe add a + (plus sign) next to the PicklistID and then have it show the results of the other query? (SELECT TEXT FROM PICKLIST WHERE PicklistID = @PicklistID???)
UPDATE 1/11/12: The PICKLISTID in the table PICKLIST is not unique or a primary key so I cannot reference it from the SURVEY table. Is there a way to give these 2 columns a relationship so that I can just change my SELECT statement in my DetailsView to include the PICKLISTID?
UPDATE 1/23/12: I'm still stuck on this. I am not getting how to make this work at all.
have 3 dropdown list one has pre set values and my post back works the other 2 has the data from the db when i try using post back on them i don't get anything in my grid view.
how do you add information from another datasource into a cell in a data grid which has the relevant information i.e order_bindingsource grid which has the information order id, item id, quantity and cost per item.
The item id I have linked to the Productbindingsource but I also need the information to be shown cost per item which is in data source products.The item id is a drop down box with the items displayed what I need is when an item is selected I need the price to show up in the cost per item box.
I am trying to create an arrayList of people. The variables, or arrays are; first name, last name, age, DOB. I am wanting to load all that into one arrayList and dataBind it so it would look like [code] Loading it into an ASP DataList. SO Fname + Lname + age + DOB are loaded on the same line/index. Not sure how to go about this. I'm sure it's an index issue..but not sure the thought process to even begin to load these elements into the "0" element, then the "1" and so on. Not puling the information from a database, just preset arrays/arrayList. ANY suggestions? ( I have it so it is dataBound to one arrayList entry as in [code] This works fine. But if I wanted to add the last name to the first name on the same line...that's were I am not seeing the connection.
In one of my projects, I have this line of code that works:
Dim newCustomersRow As EyeBaseDataSet.HistoryRow newCustomersRow = EyeBaseDataSet.History.NewHistoryRow()
In this new project I'm trying to get the same thing going, but I can't use the Row definition. I type the data set name and don't get an option for the tableRow. I don't know how else to word this, but I need to know what I have to add to the project to give me that control. In the working project it says "Class HistoryRow" and I went to the definition and it took me to the designer and showed me a Partial Public Class with System.Data.DataRow.
