Varying Quantity And Moving Data From One Table To Another

Nov 21, 2011

Currently I have two tables in a Database (Temp, Main), currently I have four fields in Temp(ID, Qty, LastDate, AddRem), and Three in Main, (ID, Qty, LastDate). I have the program set up to enter in all the information minus AddRem into Temp, then my thought was to either tag the item to remove, or add to the Main table. I'm assuming this could be done by import then update, however every avenue I've attempted has been meet with Exception errors.For the add/remove field it is linked to a Combo Box, which brings me to my other question, how would you link a specific field to say hey if it's this option then add, and if's the other remove?

Unable To Link The Inventory Table To A Datagridview Object

Jun 1, 2011

I successfully connected a remote MySQL database and it is listed in the Data Connections. My database has two tables, inventory and history, both work and I can retrieve the data from each.The problem is when I try to link the inventory table to a datagridview object. As soon as I enter the configuration wizard a red x appears in my data connections. Regardless of this, however, I can still successfully add my history table. The problem is that the inventory table name isn't visible and I get this error:<``>Could not retrieve schema information for table or view ``.The inventory table is what I need and I don't understand why it blanks out.

Add A New DataTable Column With Type "Integer"?

Feb 27, 2009

I have a dataview, and I am trying to "clone" its structure only in part, by creating a new table via code. I cut out most of the columns, so this is easier to read. My question is - Why does this always seem to add things a a string?

Later in my code, I try to sort based on "View_Order", but it acts like a string. The values sort as 1,2,20,21,22,3,4, NOT 1,2,3,4,20,21,22 like it should.

Using Cint() while moving the values from table to table didn't work for me... and the boolean becomes text as well. Is the problem in this code, or would it be elsewhere?

Private Function ConvertTable(ByVal ds As DataSet, ByVal TableName As String, ByvalWHEREexpression As String, Byval SORTexpression As String) As DataTable
'For Schedule Tasks, convert all "dates+times" to "dates only" as strings

'AddressOf' Expression Cannot Be Converted To 'integer' Because Integer Is Not A Delegate Type

May 13, 2009

I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.

After the conversion, the code look like this:

Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer

[Code]...

Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

Value Of Type 'System.Linq.IQueryable(Of Integer)' Cannot Be Converted To Integer?

Aug 11, 2011

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:

Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)

[Code]...

I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

Get Type Of Data Column?

Aug 7, 2009

The user enters information into a textbox and I would like to reflect these changes on the database. So say there is a value of 50 in the textbox and the user just deletes this and it is now "". When I try to update the database I receive an error as it expects a type of double. However, simple appending a 0 here when a value of "" is encountered will not work for me as I have a universal function to handle all of my updating needs. How would I go about determining the type of field I am dealing with (int, double, varchar) of the data table which I currently have in memory

Get Column Data Type In Datagridview For Comparison?

Dec 15, 2009

I am writing validation for a datagridview which may open a number of different tables (dependant on what the user selects). The idea is that the user will select a lookup table to edit or add too, the datagridview opens (via a binding source) and populates itself with a specific table's data.

The user can then edit the data in the rows and when they are happy update the dataset which in turn updates the database table.

This all works except there is no validation per say prior to the update. As the datagrid loads a different table dynamically I cannot predetermine table column names (without writing a mass of hard coded values) so I would rather go by the datatype of the column since the tables all follow a similar format.[code]...

How To Chose Data Type Of Column In DataSet

Feb 8, 2012

I need to read data from an Excel sheet as part of a data conversion. Certain columns contain mostly numeric data but may contain some alphanumeric data somewhere in the excel sheet. The problem is, my conversion sees the alphanumeric values as null (or blank. Using the .ToString() method returns ""). To connect to Excel, I'm creating an oledb connection, creating an OleDbDataAdapter, then filling a DataSet with the adapter.

Here's the VB code for connecting:
private _oleadpt As OleDbDataAdapter
private _oleconnection As New OleDbConnection
Dim olecomm As OleDbCommand
'_database comes from a settings file and is the full path to an excel document
Dim connstring As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & _database & ";
Extended Properties=""Excel 8.0;HDR=YES;"""
[Code] .....

I think the data adapter is determining the datatype for the columns based on the first however-many rows it looks at. It decides the columns with numbers are numeric which is the start of my problem. Changing the formatting of the column in Excel doesn't seem to affect the datatypes in my data set. Is there a way to tell the dataadapter or dataset what type of data to use for a column? Or should I try to cast the data in my SQL statement?

Adding A Column To An Access Data Table Through VB?

Nov 22, 2011

I have already binded a data source from Access to my visual basic program but need to add a True/False column to two of the tables. I could do this manually in access and re-bind the sources but that would take up too much of my time so I wanted to know if I'm using the proper code to add a column to the data table directly from VB? Here is the code I want to try but I don't know where to place it?

OleDbCommand = OleDbCommand("ALTER TABLE tableName ADD
FieldName DataType");
(something).Connection = OleDbConnection;

[Code]....

I'm not sure what goes into the "something" parenthesis and where this code must go. I already tried editting through the data designer but although it shows the column in the DataGridView, it does not save any data or the column into the actual access file.

Run A SQL Statement To UPDATE A Column In A Table With New Data?

Apr 27, 2012

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?

Imports System.Data.OleDb
Module Module1
Dim cn As OleDbConnection
