I converted some code from vb6 to vb2005 that opens a recordset and populates a listbox
with about 8,000 names. It uses classic ado. The vb6 code does it in about 0.75 of a second, the first vb2005 code does it in about 5.5 seconds while the second vb2005 code does it in about 4.5 seconds. Is there any way to improve the vb2005 performance a fair bit more?

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I have created a parameterized query in my tableadapter. Here is the SQL:
SELECT CalcinerID, Comments, CorrectiveActions, CrucibleOxideWt, CrucibleWeight, DCPressure, DCTemperature,
Date, DischargePressure, FeedPressure, FiredCrucibleOxideWt, GmSampleWt, LIMSNumber, LotNumber, MaterialType,
OperatorID, QualLabOperator, QualLabTimeStamp, RecordID, ToteBinNumber [code]....
When I use the Execute Query button in the Tableadapter Query Builder, the query works fine; I get all the rows I expect. However, when I run this in my code, the query behaves like an equality statement (i.e. Lotnumber = @Lotnumber) rather than a LIKE statement (Lotnumber LIKE '%' + @Lotnumber + '%').Here is the code that is not behaving correctly. Note that I have a textbox, LotSearchTextbox, where I enter the portion of the Lotnumber that I want to use as the filter. I also have a button, LotSearchButton:
Private Sub LotSearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LotSearchButton.Click
Try
Dim SomeNumber As Integer = Me.LotCalcinerO2TableAdapter.FillByLotNumber(Me.CalcinerDBDataSet.LotCalcinerO2,[code].....
why the query works in the Query Builder but not in the code?
I have a VB.NET Windows form with a datagrid on it. I also have a combobox on the for (outside the datagrid).The purpose of this combobox is to limit or filter the records shown in the datagrid
database is Access MDB
table name table1 field name = field1
another question
i have 2 tables table 1 for customers include cust_code and cus_name
in table2 emp_name cus_code
i need to get the data from table 1 with information in table2 cus_code
In my Form1 i have a datagrid with coulmns: CarName , CarModel , CarColor , CarOwner (there are a lot of data).
I added queries (textboxes that the user writes in text) that can "filter" data when the user want to choose specific CarName or specific CarModel.
textbox1 = CarName
textbox2 = CarModel
textbox3 = CarColor
textbox4 = CarOwner
If the user writes text in TextBox1 then the data shown in the DataGrid is filtered.What if the user want to choose also (!) a carOwner? I know how to use AND statements, but if the user didn't specified a carOwner non of the data is shown although there are this kind of data.

I created a form with a datagrid to show data stored in an Access database. It shows the data correctly, using the code:
[code]...
("compras" is the table name and "Comprasver" is the dataset name).The form also has 3 textboxes and 1 DateTimePicker.Then I created a sql query to allow the user to search within 4 fields of the table (field1, field2 and field4 get the data in the textboxes and field3 gets it in the DateTimePicker). The query looks like this: SELECT field1, field2, field3, field4, field5 FROM compras where field1 like "%"+?+"%" and field2 like "%"+?+"%" and field3 like "%"+?+"%" and field5 like "%"+?+"%" field4 is not an important search criteria, so I didn't include it in the query. Field1 and field2 are both string type. Field3 is a Date type and field4 is integer.Once I made the query, it automatically added a toolstrip with a code, which I cut and pasted in my "Search" button "click" event. The code looks like this:
[code]...
But every time I try to search, no matter which criterias I fill in (even if I fill in none of them), I get an error message saying something like the conversion of the "" string into Integer is not valid (my Visual Studio version is in Spanish, so I don't know how to exactly translate the error message).It's supposed to let the user fill in one, more or all search criterias (all 4 search fields).I found out that if I delete from the query the two fields that don't have String type data, it works correctly. What should I do in order to be able to use the Date and Integer type fields as search criterias too?
How to make query from mutiple datagrid so that the data from datagrid will create chart?
View 10 RepliesI'm using Visual Studio 2005, and I have a datagrid connected to a table from an Access database.
I added 4 textboxes so the user can type search filters to search within the table and a "search" button.
Then, I created a query using the "add query" tool on the datagrid. I wrote it like: select field1, field2, field3, field4, field5, field6 from table where field1=? and field2 like "%"+?+"%" and field3 like "%"+?+"%"
and field4 like "%"+?+"%"
Both field5 and field6 aren't search criterias, so I didn't add them to the query. Once the query was created, I replaced the parameters inside the procedure with my textbox1.text, textbox2.text, textbox3.text, textbox4.text and then cut and pasted the whole thing inside my SEARCH button click event, so the query is executed when the user clicks on the button.
Now the problem is: when I search using the first field it goes ok, but when I try to search by any of the other fields it returns zero results, even though I double-checked I had written the words correctly. I don't know why it does this. I already tried deleting the datagrid and creating it again.[code]...

I have a materials library that I am adding into a database, the library has a number of columns, the one I am concerened with here is the Item Code column.
All Item codes start with 'M' and then have an integer after them (M1, M2, M3.....M9999 etc) What I want to do is to auto generate the next available item code when a new line is added.
The next available code should be based on the last value in the 'Item Code' Datagrid View column but I don't know how to do this.
I have tried getting the next available code from the database but this doesnt work as I want it to.

I am trying to code the datagrid to be the exact total of all of the columns eliminating the horizontal scrollbar and then next I will eliminate the vertical scrollbar for any account that has less than five records.

I am using VB.Net 2003 with an Access 2000 database. The program contains three options for the content of a DataGrid, each from a different table. I have finished programming the DataGrid which loads as the default when the program starts.When I run the program the DataDrid appears, but it is empty, except for a small box with a "+" in it. I click the + and the table name appears, I click the table name and the DataGrid is populated exactly as I wanted it.
