Used the BindingSource. . :: . Filter Property description to verify how filters work.
The example uses the following filter source1.Filter = "artist LIKE 'Dave Matthews'" If I change the filter to source1.Filter = "artist LIKE 'Dave%M%'" by using 2 wildcards I run into a EvaluateException How do I use a filter with more then one wildcard?
I am trying to filter the results of a datagridviw using the bindingsource.filter method.
Dim filters(2) As String

The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.
I have a search page, which iam using to search the database fields which holds the technical articles. The fields that iam searching are varchar(max).
Everything is fine..., I want to show the results with the first found instance of searched keywords in bold and some 70 to 100 chars before and after.
need a quick reply looking for code that will filter my datagrid with all the results between 2 dates in 2 datatimepickers. My table is not bound to the database. I'm looking for code that will work when the search button is pressed.
View 3 RepliesI have a data bound datagridview on my form. I need the datagridview to sort by oldest date, and then return only the 150 oldest. The goal is to export the 150 rows with the oldest date to a .csv file and then update the date column to the current date for only those 150.
Here is what I have so far:
Dim appPath As String = Path.GetDirectoryName(Application.ExecutablePath)
Dim tdate As Date
tdate = Today.Date
'sort datelastemailed by oldest to be emailed first
DataGridView1.Sort(DateLastEmailedDataGridViewTextBoxColumn,
[Code] ....
I can get it filter by the column "status" and then sort by "datelastemailed". I can also get it to export only those 150 to the .csv file. My issue is that I need only those 150 to have their date column updated to today's date and then saved to the database. The only way I can see to get that done is to set a max number of rows for my databound datagridview and then loop through each row in the date column. How I can create a filter that limits results?
I'm trying to create a Windows form application which uses a few data grid views to pull data back from a SQL Server database. I've managed to get the data back okay from the tables but what I want to do is filter that data dynamically based on values input by the user from a combo box and a date time picker. Each of the data grids display production data for a machine but the combo box and date time picker will allow the data to be filtered by shift and date respectively - how to I pass the values of these to the SQL query returning the data?
View 4 Repliesim just starting to work with some database stuff, and ive got data binding done but im a little stuck with filtering. Ive got a test project, which has
-- listbox (bound to column 2/firstname)
-- Combo box (Has items added, with the same names as the items in colunm 3. so it has 'RPG' and 'Puzzle')
Now what im trying to do is when the item in the combobox is changed say to 'RPG' only items in the db which have 'RPG' in the surname column are displayed in the listbox. Been Google'ing and reading but all i can find is examples relating to a dataview and i cant get them to work/adapt to my situation.

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

I have created a program that randomly produces simple maths questions and saves them to a SQL Server (SQL Server 2008 R2). The code looks fine and works if I step through the program. Each pass it creates a random question answer and saves them to the database. However, if I run it (Debug/Release), the program produces a question and answer but repeats it in the database.

I am having a SP run in my VB application every 10 seconds to check for any new rows that have been inserted to the database since the last check. What is the best way to do this? Most likely it will be 0 or 1 rows, but I am afraid at random times it maybe more than 1 and so I thought I would fill it in a DataSet, but I came in here to see if there are any other better ways. If dataset is the best way, how do I do a For Each Row in the dataset to process some VB code for each row?

View 1 RepliesI am running VB from VS2005. I just had to change a program to revises the logon info for a database. When I run build, I get success and there are no errors in the error page. The only thing I can think is that the first two times I ran the build I have the configuration set for 2 copies. It never bothered me before but some update may have come in and changed that. I reset it to 5 and that did not help. I closed VS and re-opened, no help. I created a new folder and moved the contents of the release folder out so that nothing was left. After running the build several more times, the release folder is still blank.

View 1 RepliesI'm having some trouble extracting a distinct value out of a dataset.. I have a database table with 5 fields,
ProjectName, VendorName, ExpenseType; TxnDate; Amount
In VB6 I would have several different recordsets opened one after another to
A. Find all the unique project names within the table (and put them into a For/Next loop)
B. For each unique project name open a recordset to look up unique vendor names applicable to it (add For/Next)
C. For each unique projname, unique vend combination find unique exptype....for next loop....
D. For each unique projname, vendor name, exptype, date combination, sum up the dollar amounts...
The end effect is that you have a net dollar amount for each unique combination of project/vendor/expensetype/date.I dont like doing it like this because I have to keep hitting the database, I wanted to know if there was something I could do within the actual dataset which will be filled when I open the application with the values of the entire table..I got to ds.tables("Text").select.distinct( ....not sure how to proceed and everthing I've read online leads me into a complicated direction of creating new datatables...
