View 2 RepliesI 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.
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
View 3 RepliesI 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?
View 8 RepliesI am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;
Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click
[Code]...
This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.
Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.
in DataSet ds I have "tbl1" as parent table and "tbl2" as childtablehow to show both table in datagridview if column id in "tbl1" related to column headerId in "tbl2" ?

My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..
I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..
When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:
Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"

I am working with VB.net and Sql server 2005. I am creating a mini application to load data to a database in SQL.Presently, I have a form with a browse button where you can select the file you want to load. This file extension for example is E:DatatobeLoaded est.txt. This file extension is then shown on a text box (TextBox1) on the form.
I have another button called BtnExport. What I want to do is when this button is clicked the code reads the data in the table test.txt, and connects to SQL and creates a table. Now, by default the first line will be column names. (It is similar to the create table option you have when you import data to SQL).
The sql Connection is :

Made what I think was a tactical error by using lots of 3rd party controls that made it easy to get stuff going but resulted in carrying a lot of baggage with my apps. Now it is finally time to switch to VB.Net and I want to avoid 3rd party controls as much as possible.
The database is MS Access. Master table called GroupName, key GroupID, string GroupName. Child table is GroupCustomer, key GroupID+CustomerID. Two datagridviews, GroupName on top, CustomerGroup on bottom. I've studied the one to many videos and howto's and it is easy and works like a champ. Fill the tables, sort, filter, add, update, delete, all is well.
Top grid
GroupID1 GroupName1
GroupID2 GroupName2
and so on.....
[code]....
However, adding a third table is where I get into trouble. In the bottom grid I want to link customerID to the Customer table to pick up Name, address, city, state & zip for display purposes. I've modified the table adapter to create a select query returning the lookup data with the groupID and customerID. It displays nicely on the Fill but doesn't automatically refresh the customer lookup fields when I add or change a customerID and I can't seem to update new records or deletes. The only table in my query that I want to update is the GroupCustomer table but the query is not updateable.I've been trying to figure this out, read articles, learn, step back and think but am still stuck. how to use the controls that come with VS2010.
I am reading a Sql table into a dataGridView. The SQL Table contains many nulls and my select query is not returning them. I would like to include them with a wildcard search.

View 3 RepliesI am using vb.net to create a Word table. Everything works fine, except that it is very slow. It takes about 0.34 seconds to create each cell in the table. I am using an HP machine with i7 processor and 12 GB of RAM. At 0.34 seconds per cell, times 7 columns, times 189 rows ~ 7.5 minutes to create a small table! I must be doing something wrong, but I have no idea what it could be. The table looks looks fine.

oWord.Visible = False

I want to create an index on my table. I used the following command Code:

cn.Open()
cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT (ITEM_NO)", cn)
cmd.ExecuteNonQuery()
Now I want to use this. Is there a file created with some extension when i do an Indexing?. Is the above statment actually index the field, ITEM_NO or do i have to use ALTER TABLE command? Currently I am getting error "Cannot execute data definition statements on linked data sources"
I have no problem creating it. I have created a yes/no (bit) field and set it's default to False. once created if i open the database this column shows data as 0 or -1 as expected. If i created it in Access it would display as a checkbox
