I want to copy Header Data from one table to another. I know how to do this if the table data is exactly the same, but I need to generate a new HeaderKey for the destination table.Example - I am copying SalesOrder Header Data into the PickList Header Table, but I need to also add a PickListHeaderKey when I do so. It cannot be the SalesOrderHeaderKey which will be copied also.
I have a database that has two tables in it. One is a table of items (table1) and the other is the table of current items (table2).On form load I need to generate a random amount of the items from table1 and populate table2 with them. I was trying to do something like this:
I'm writing an app to print a list of beers that are currently on tap at the restaurant where I work part-time. We have 29 taps and dozens of different beers. I have 2 tables in a database (one with the "master list" of all the beers and an "on tap" one with one entry per tap). Each database entry includes fields for name, brewer, location, style and ABV. So far I've made a GUI with 29 combo boxes (one for each tap) and 2 buttons (one that opens a dialog box to modify the "master list" and one to print the list). The idea was to make it as simple as possible since the people who use it aren't great with computers and are often in a hurry.
Each combo box drops down the whole master list of beers and I'd like for the selected beer to be written to the corresponding index in the "on tap" table. My idea is to then extract the data from the "on tap" table and print it. I haven't done any coding yet, really, just drag-and-drop.It's frustrating since I know how I'd do the back end in C or C++, but not in VB. The reverse is true for the GUI.
I have a login form that consists of 2 text boxes: txtUser, txtPass. Now these are not bound to any data table & I don't what them to be bound. When a new user enters his user name & password, I want to add these on a data table that has two columns: User, Pass. Data table information: Data Source = Login.accdb, Data table = LoginTable, Connection = LoginCn. I use visual basic 2010. So how do I do this?
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 currently have this working already for one of my combo box's, but when i try to use the same code i get this error ''There is no row at position 6.'' . The are 2 fields in the table asset_type_id, asset_type_name', im trying to dispaly the values in a combo box for the field 'asset_type_name.
the code for ' Friend Sub RetrieveCustomerInformation2()' works but the other friend sub throws the error. Imports System.Data.SqlClient Imports System.Data Imports System Imports System.Data.OleDb
I have 1 access database with 3 tables How do I make the combobox get data from one table and input it to another table?ex.I have a table with all my Carriers and another table with jobs that are assigned to Carriers?
I'm experiencing some weird behavior when trying to modify some DataTable objects. Upon the second call to the subroutine, I get the following error when I to copy the source DataTable to a working set:
System.Data.ConstraintException was caught Message="Column 'pk' is constrained to be unique. Value
Now I am trying to copy the MS access table(hoping to keep the input mask). I have the table copying and renaming, but it fails to keep the input mask... So far this copies and clears the table, is there anything I am missing to make it keep the input mask
vb Query = "SELECT * INTO [test] FROM [tblAccounts] WHERE 1=2" comm = New OleDbCommand(Query, conn)
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 data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...
I have three table and I want to put the three table's data in one variable and from that variable i will produce the datatable and then want to write the data in CSV file.I am Following this step..
Currently using VB 2008 with MS Access 2003.I have Two Tables with Names - " Company_Data" & "User_Data" in which i have the following columns.....
Company_Data Name|Age|Department|Salary User_Data Name|Age|Department|Updated On
Now, Is there any code that can do the following:when i select a name in the combo box on the form (The list in the combo box is from the Name in the Company_Data table) and click update.It should copy the Details of the Record from Company_Data to User_Data with the current date in "Updated on" column. Note that the columns are not exactly Same. (Salary is not necessary in the User_Data)?
I really need your help. I want to query in a table in MS SQL using a data in another table.This is the query I've constructed : "SELECT TABLE1.FIELD1,TABLE1.FIELD2 FROM TABLE1, TABLE2.[code]
have made the data table in vb code, and it works flawlessly. It gets its values from labels which are part of a calculation.It shows the information to the user in a datagridview. Now i would like it to add new rows and fill them in if the user has already entered the data once and it has been logged in the datagridview.here is the current
'DATA TABLE Dim Table1 As DataTable Table1 = New DataTable("CF Log")
I am trying to copy a table in a database into another database on another connection in VB.NET, using OleDb. If they were on the same connection I would just use SELECT INTO, but they are not. I have two different OleDbConnection and cannot see an easy way to do this.
Right now I am attempting to just copy the database into a DataTable using an OleDbDataAdapter, and then loop through the DataTable and insert every record into the target database one at a time. This obviously takes a ton of time for the large DB I could potentially be dealing with, and I have to deal with escaping strings, null values, etc.
edit - just to make this more clear: I have two OleDbConnection objects, one is linked directly to a local .mdb file on my computer (JET). The other is linked to a database on our servers (SQLOLEDB). I am wanting to do this:
"SELECT * FROM fromDB INTO toDB"
But I can't because fromDB and toDB are on different connections, and the OleDbCommand object is only attached to one. The only way I can see how to do this is to connect to fromDB, copy it into a DataTable, connect to toDB, and copy all of the data in the DataTable row by row into toDB. I was wondering if there is an easier way to do this.
Let's say, I have something like a table in the WebBrowser component, it's not actually a table, because the data organized in flash, but, it's organized like a table, it has like rows and columns. You can see more in the attached file. Can I transform this text organized as table into DataGridView or some another tool that serves as table. like_a_table.JPG
I have a large form that is set up from master-detail datasets in Visual Studio 2008.I havene master table with a large amount of detail tables. Several of the detail tables also have detail tables linked.Now I need to add a master table that sits on top of my existing master table making it a detail table.
I created a function that creates a global temporary table to stage data from a excel sheet I need the table to persist for me to map the columns using a form. The table is still there when the code goes back to the sub that calls the function until I call the form where I do the mapping. I am trying to avoid create/drop table scenario with a perm stage table.How can I get this table to persist until the data gets loaded into the perm table?
I have a query that I have to run that requires me to get rows from a table based on the value of a field in another table (which I have gotten earlier). I currently have it done like this (simplified).
I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable" Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.
dr = dbDset.Tables(0).Rows(CurIndex) dr.Delete() dbAdp.Update(dbDset.Tables("addresses"))
