I have a windows form program that pulls data from a sql server. That same data is being read from a ASP.NET website that sets properties for the site. The SQL server has 3 tables: tblWebPage, tblObjects, tblProperties. and 6 views for the 6 web page: vWebPage01, vWebPage02, vWebPage03..ect. When the program loads you see buttons for each web page on the site. When the user clicks on the Home Page it loads this data: [code]Now, the problem lies in updating vWebPage02, vWebPage03, ect.. I assume with the same data I can copy my form with the code and change the form name and the data set to build and update. So that's just what I did changed the form name where needed and changed "vWebPage01" to "vWebPage02".When I tested the program My "vWebPage01" form it built and updated no problem. when I went to test "vWebPage02" it built the dataset and table adapter fine but it did not update at all.
I have this code to edit the datarow of my table adapter but t doesnt update the table. I think i have a missing code that's why but i cant figured it out. by the way im using vb2008 and SQL as my database. [code]
i'm using vb 2008 and local database sql server compact 3.5 to build a application.the problem is that i can't insert a new data to the database from the app. i'm wrote the query right at dataset and using table adapter. but when i call the query, it succeed but the data don't exist at database.why when i add data, it's not working. actually when i run it, it says that adding process is success, no error, and it shows at the datagrid. but when i look at database. the data that i add is not there.and in tableadapter, i also make sortData, seachData query, i can use both of them perfectly when i run the app.so, i really confuse why is the insert query didn't work.
Honestly I do not understand why I need to write code to update a databse and why it stores it localy. I'd simply rather the system update the individual row after it is scrolled off of.
In either case since I guess I can't do that.
Here is some code in a button on a form
Try ItemsTableAdapter.Update(NewCreationsDataSet1.Items) LineCodeTableAdapter.Update(NewCreationsDataSet1.LineCode) Catch ex As Exception
and what I'd like to do is when users edit something on this form that they post the changes to a table called exceptionsedit which is not part of that dataset. What I don't know how to do is to how to insert those edits to the exceptionsedit table.
I have a datasource linked to a table in a database.When I wnated to display this data on a form, I just dragged the datasource onto the form and it did everything for me, including the code to fill it;
My problem, is that this program will have multiple users, and I don't other users to be able to see each others data. So the problem with the above statement is that it fills the table with ALL the data in the datasource. How can I make it only display data that is for a specific user?Here's the code that is used to fill the tableadapter:
Private Sub frmViewCurrent_Load(ByVal[code].......
I am having trouble with a table adapter i am working on. In the table adaptor query i am having adaptor take a sum of the data that falls within a date range in a few columns. then i have some text boxes on my program refencing the columns that are being summed together. The program then gives me an error when i go to run the function.
I've made a dataset using the dataset designer, and I'm trying to add a column to reflect changes made to the database (added a column, nothing fancy). Is there a way to 'refresh' the dataset schema from the datasource without deleting my adapter (and all the methods and queries I've created)?
ve 2 forms form1 & form2.form1 has primary key(parent table) & form2 has the foreign key(child table) me.mytableadapter.update(me.dataset.mytable)is working f9 but in form2 when i try to use me.secondTableadapter.updatehere problem comes the update function is not coming neither recognized by form2 .can anybody tell me why is it ?
I have a form that has a datagridview and a table adapter that displays data from a SQL database. What I'd like to do is that when edits are made to the data in the datagrid, I'd like to post all of the data back to the table. I know that you can do that with a dataset and a data adapter, but I don't know how to do that with a table adapter. Here is the code for my page:
Public Class ExceptionEdit Private Sub ExceptionEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'TODO: This line of code loads data into the 'MDRDataSet.scratchpad3' table. You can move, or remove it, as needed.
[code]....
When people click on the Save Exception button, I'd like to save back to the update the database with the new data.
I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.
I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update() TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.
As the title says, when I attempt to update a row in a table in a database, I recieve an InvalidCastException. I am unsure why, since the variables I am using should be, and indeed, when I check them at runtime, are filled with the correct data.
I am trying to update using the method wherein the row that is being updated is identified with all the variables already stored. Interestingly, Intellisense is telling me that EntryID, the primary key, is only necessary in it's original form, and that the variables that I am attempting to update have question marks after their type.
when trying to use the update command for my table adapter, i get the following error.
[Code]...
i've used the same commands several times and even tried copying the code from another project and importing that table and still get the same error. am i missing a namespace or class or something?
when i try to insert data from database into dataset using data adapter, it takes long time, i want to use hourglass but i'm confused how or when i type the code so user will know that application still work.
I have an application in VB2008 and using SQL Server 2005 Express Edition. I found an error in a value that I had entered in the SQL Table and want to correct it. All I needed to do was to change a numerical value in one of the columns from 18.4 to 16.4. This table is used to fill a combobox drop down menu in the application. After I changed the number in the data row, I saved the change and ran the applocation in debug but the original number still appears in the drop down menu. If I exit Visual Studio and re-open it, the change still appears in the database table but does not appear in the combobox, when I run it in bebug.I have made changes like this many times in this application and this database table, As I recall, all I had to do was save the change and I have never had it fail to update the change in the data row.
I have looked through the entire internet (well that's what it feels like) to find this out.Tables - Authors and Titles add new title must be linked to an author, so I need to check that the author exists, if so, update the titles table with the user data from the textboxes. If the author does not exist, I need to insert the author first & last name into the author table, then the title info into the title table.this is in VB, using ASP.NET, and my database is a file, I'm not using SQL server, just Visual Studio 2008.
Dim insertParameters As New ListDictionary() insertParameters.Add("ISBN", ISBNTextBox.Text) insertParameters.Add("Title", titleTextBox.Text)
which is supposed to get all the data from my table and set it as the datasource of a DataGridView. You can see where I put in two msgbox's to view how many columns are in the DGV before and after the "update". The first count gives me 22, which is the correct number. After the .DataSource and .DataMember lines are ran, the count jumps to 41 and I have no clue why. All I want to do is clear a dataset, fill it with the new data and set it as the data source of a datagridview. It appears the info is being saved to the table correctly too.
I'm not so good in databases and SQL. At the moment, I have a interface of a simple payroll system as well as a database design. I got 4 tables consist of Employee, Payroll, Deduction and Salary as you can see in the picture link below. Btw, I'm using VB 2008 express edition and mysql 2008.

My question: How can I link them properly? did I link them properly? How can I save the data into 3 different table from the interface u can see.
Attempting to run an SQL statement to UPDATE a column in a table with new data. The column being updated is defined as varchar(40) and the new data is 41 bytes (varchar(41)). I get a generic 'data will be truncated' error message, but no detail on which column caused the problem. I've attached a sample VB program to illustrate the issue. In this scenario, Company is defined as varchar(40).
My question: Can I get a more detailed error message? i.e. can I get an error message that tells me the row and column that the truncation occurs in? Often times, I may be updating hundreds or thousands of rows and only one value in one column from the source file is too large for a database cell. As a related question, does each OLEDB provider create its own error messages. i.e. will the MS SQL Server OLEDB provider potentially give different text in the error message than say the MS Jet OLEDB provider?

I've just finished my first vb.net application and have a question about setting up data sets and data adapters.It seems like I do a lot of repetition in coding and I'm wondering if there's a better way to set them up.Below is the coding I use to set up a data adapter (daAddSpeaker) and a data set (dsAddSpeaker).The purpose of this coding is for the user to add a speaker name to an Access table thru a windows form.The coding works as intended but I'm wondering why I have to repeat "SELECT * FROM tlkpSpeaker" and refer to "tlkpSpeaker" so often.[code]
I have a gridview loaded with data from my database and a gridview swapping function which after exchanging data between rows with a column call "Priority", I want to save these changes back to my database. Only the "Priority" column value will be change, how do I update only that Column of my dataset table to my SQL database?
I'm using VB 2010 Express with a local Access DB. I am having trouble determing whether there are changes in a DataGridView to save back to the underlying DB.
The DB has been copied to the project directory and its properties (by selecting it in the Solution Explorer) include Copy to Output Directory: Copy Always, so I know that any changes I make when running a build will disappear on the next build. The problem I'm having is within a run / test session, working with the application.
The Access database has the following connection string, with Application scope:
I am getting an incorrect repsonse after an update to a table. In my RowUpdating event I have the following code which builds an Update Parameter to call an SP to update a table. I must be doing something wrong but everything runs fine. My rowsAffected variable reports 1 after the update, but the table never gets the data.[code]I found a solution that is working. On the original DataSource for the update command I needed to add the following.[code]This in essence allows the original data source to call the SP. Note: that the command type needs to stay as TEXT not Stored Procedure as one might think.
