Nov 30, 2010

This is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.

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?
