Datagridview Has Wrong Number Of Columns When Binding To A Table
Nov 4, 2011
I need to have multiple lines in a cell, so I use DataGridViewTextBoxColumn.DefaultCellStyle.WrapMode =DataGridViewTriState.True. I add columns (datagridviewtextboxcolumn) in designer. Then bound datagridview to a table which has exact the same columns as datagridview. Then I find that datagridview has duplicate columns: the first column is empty (which I guess is added through designer), the second column is filled with data from table. My question is how to correctly allow multi-lines and bound to a table at the same time?
In Designer
Friend WithEvents DGV As New System.Windows.Forms.DataGridView
Friend WithEvents columnClient As System.Windows.Forms.DataGridViewTextBoxColumn
Friend WithEvents columnAccount As System.Windows.Forms.DataGridViewTextBoxColumn
Me.DGV.Columns.AddRange(New System.Windows.Forms.DataGridViewColumn()
[Code].....

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

I'm working with Microsoft Word and trying to generate a table with headings that may span one to three columns. I'm having trouble figuring out how to do this. The table should look something like the following:Counters
Times (hrs)
Flows (gals)
Day
Regens
Well Starts

To get it to look this way, I'm not exactly sure what to do from VB.

I have set up at DataGridView "cdgvExp" for data entry. cdgvExp.Datasource = ExpTab. The datagridview can accept new rows according to how many entries there are. I will then use the data in ExpTab. The Fourth colum is called "Lot" and is a combobox in the datagridview. The goal is to have the Combobox in the fourth column have the datasource be LotTab which is populated according to other choices in the form. I am hunting for something that would work like an independant combobox like cbLots.datasource = LotsTab
How do I dynamically set the Datasource and Datamember of a combobox that is already set up in a datagridview?

I am using data grid view in Windows Form standalone application to display items as excel spread sheet in VB.NET. I got a table named CostTypes with column names [CostTypeID, CostType] and values [1,External] and [2,Internal] (These are constant but more values can be added to table).
I want to create columns with names of the values[External , Internal] in DataGridView. If I use databiding directly I get columns [CostTypeID,CostType] which is not what I am looking for.

I have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.

I am trying to customize the color of a microsoft graph chart in access using vba but my chart.seriescollection.count doesn't give me the right count?! It is stuck at 4 I don't know why. However, I've created a recordset from the query used to create the graph and the DAO fields are right. I tried to refresh the graph, close it and open it, reboot. My graph displays properly with the right data but I can't set the colors like I want and it is the most important part of it because I am plotting rock codes.

I generally use VB.Net for programming but I have been delegated to a VBA project that would benefit from using script control for running script. Here is sample code but errors out on the .Run line of code. I can do this in VB.Net easy but can't get it to work in vba.
ERROR = Wrong number of arguments or invalid property assignment
Option Explicit
Dim sc As New ScriptControl
Sub RunFunctions()

Using the .Eval function from the script control object runs ok in vba but does not run scripts.

My problem is with the tickets table, I have listed the user that created the ticket, the tech who will solve the ticket and a user that over sees the ticket. All three users reference the users table. So how do I can I query the tickets table and get all three users that reference the same table storing the users?
Table1: Tickets
1) Ticketnumber
2) EnteredBy User 100
3) Issue

What I can do now is something like this:
Select Ticketnumber, EnteredBy, Issue, UserName FROM Tickets INNER JOIN Users

Rather than running numerous queries in Access I am trying to write a front end for a DB2 database. The Access database is getting to a size that it is causing Access 2007 to have reliability issues and frequent compacting is required. I have created the Dataset, the Table Adaptors, and the Connection String already, but when I put in a bit of code in to fill the Table Adaptors the remote connection I have to work is going crazy (chewed up about 180MB before I realised it was pulling data from work).
Before I started the project I copied the .accdb to my local PC HDD and I pointed the connection string to it, but it still looks like it is trying to pull data from the work network. If it was a small database I wouldnt be concerned but it is pulling major data every time I run it. I have only 2 out of the 4 Table Adaptors running and it didnt fill them even after 10 minutes.
Here is the code I was trying to run... Server name has been substituted for Server for obvious work reasons.
Because the tables are so large I was looking for a way to pull only the columns I need to from the tables, I tried adding .SOFT_ID to the first line of code but the TA spat the dummy message below...
Value of type 'System.Data.DataColumn' cannot be converted to Application_Name.DS_DB2Database.Server_SOFTDataTable'.
Code:
Me.TA_ServerSOFT.Fill(Me.DS_DB2Database.ServerSOFT.SOFT_ID)
Me.TA_ServerSOFT_FOUND.Fill(Me.DS_DB2Database.ServerSOFT_FOUND)
Me.TA_ServerHARD.Fill(Me.DS_DB2Database.ServerHARD)
Me.TA_ServerREF_SUP.Fill(Me.DS_DB2Database.ServerREF_SUP)
I would also like to pull just the data columns I need to speed up the query.
Note: In case youre wondering why I am not connecting directly to the DB2 database. I currently dont know where it is stored and while leveraging Access I am trying to put a level of separation between the app and the db for the time being, later I will try connect directly.
