Error In Binding Data After Filtering
Jan 12, 2009I am trying to make a small application and I have a problem in binding data after filtering them.I use VB 2005 and SQL 2005. The data are shown in datagridview and I bind the selected row to the text boxes of the form. eg.[code]Later on I search the data for some records and at the same time I remove the databinding. When I try to bind them again it does not work because the index is from the whole data and not the filter data.I have fixed the problem in another situation where I had autonumberin as a primary key and I used this as an index. In this case I use platesno as an index and it's not working.

View 4 RepliesDataGridView Column Binding Filtering?
Sep 14, 2009I have two database tables in SQL Server Express 2008 with the following layouts.
DATA
-------
id
fundKey
amount
fiscalYear
FUNDS
-------
fundKey
fundDescription[code]....
These two tables are related on fiscalYear and fundKey. So if you were to look at the first line in the DATA table you would get:
1,General,2700,2008
I'm trying to create a front-end for this using VB2008. I thought a DataGridView (DGV) would work well for this. So I create a small app to test out my theory. I put a DGV on it and setup a data source to the DATA table using the designer and it works great. Then I change the fundKey column to be databound to the FUNDS column, looking up the fundDescription based on the fundKey. I also change it to a combobox column because in the future I would like other users to easily change the value. And all of this works well.My problem is in that combobox column, all the fund values are listed as options.So it lists: General, Indirect, General, Sponsored. I would like it to list only the values for the appropriate fiscal year. So if that row is for fiscalYear 2008, the fund options should be General and Indirect. And if it's 2009 the options should be General and Sponsored.What is the best way to do this? I thought about setting up views on the SQL Server side and having two datasets in the app and switching between them.

[2008] Data Binding Text Boxes Not Updating To Different Record?
Jan 21, 2009 there is a tab control system. It relies on only five text boxes, and their bindings change when the tab is changed The relevant information is displayed. However, if I navigate to a different record...You can see that the same information is displayed in the tab control text boxes, and not the employee's details I just selected in the data grid or the navigation. How can I fix this? I'm not sure what's gone wrong here. Here's the code that changes the text boxes upon changing tab...

Buffer/Array - Safe Application That Contains 3 Threads - Data Acquisition And Decoding - Data Graphing - FFT And Filtering
Aug 26, 2009I am trying to write a thread safe application that contains 3 threads : -
1 - Data acquisition and decoding
2- Data graphing
3 - FFT and filtering
Thread 1 is collecting bytes from the serial port and converting them int integers (so taking two bytes) after is has captured 64 Bytes and converted into 32 integers, it then needs to pass the array to the graphing thread.
The graphing thread then plots the data and waits for more data.
Thread 3 also waits until thread one has collected 2023 integers and takes these and performs some FFT calculations (which take time).
My question is how do i share the arrays between the three threads without deadlocking the program? as the serial thread will be flying around reasonable fast (1000 bytes per second) so it will synclock onto the shared buffers for most of the time.
Originally i was going to use two synchronised queues, so when thread 1 has collected 32 bytes it queues the data into the graph queue, and once it has collected 2023 it queues the data into the FFT queue.
Then thread 2 and 3 can simple dequeue the data.
However using queues has the overhead of casting the data in and out, and as i know the data type i was planning on using two arrays :-
Dim GraphArray() as ushort
Dim FFTArray() as ushort
Then Thread 1 adds data to each thread, and thread 2 and 3 simple wait until the correct amount of data is available before removing the data. my question is there an array type that allows me to remove x amount of data from an array?
Because i cannot do this easily with the ararys defined as above (GraphArray, FFTArray), as i was planning on making them 1mByte and allowing thread 1 to fill them Knowing they should never overflow and then let thread 2 and 3 remove x amout of bytes at a time unless there is a better way of doing it
Filtering Data More Than Once?
Dec 2, 2009I created a query on a Access database, which I would like to show with the datagridview. So, I created a new table adapter with my query, which creates as well the datatable tbl1. Then, the wizard created the datagridview for me, showing the correct data. Now, I would like to filter these rows: I already read it is possible to do it by simply clicking "Add query...", but I would like to do it in a different way. I have some comboboxes, and I would like to use the strings inside them to filter my table tbl1. Is it possible to apply those queries one after the other on my datatable tbl1? I am able to filter only once with:
Me.tbl1TableAdapter.FillBySomething(Me.DataSet.tbl1, params...)
But, if I wanted to filter the result again?

View 9 RepliesFiltering Datagridview Using Unbound Text Box?
Dec 29, 2009I am creating a form to display data in a DataGrid that is bound to a .mdb Query. I am semi-experienced in VB6 Programming, but relatively new to VS8 and all of the features. I created the form, and have the DataGrid that displays all of the info in the query. I would like to be able to filter the form to only display data that matches what the user would type into a text box on the form (I have a text box created as well as a command button that says "Search by...").
Additional Info - I do not have, nor do I want, the DataGrid Navigator displayed on the form.
I want the user to be able to type a value in the text box (Rack Number), then press the button (Search by Rack Number) to only display the data in the DataGrid that corresponds to the rack that matches the text box.
Filtering What Characters Can Be Added To A Text Box?
Jan 27, 2010I have a series of text boxes on my form, and my client wants me to filter out characters that aren't allowed, for example in the name field you cannot have symbols or numbers.
Now, he wants it so when you try and put in a special character it simply will not get entered into the text box. I know the logistics to this, but I'm not sure how I would go about coding it.
Basically what needs to happen is when the user types in characters like $, ^, 5, * etc, a function needs to recognise this and stop them from being entered into the textbox, whether it means deleting them as soon as they go in or interrupting the action altogether.
DataGridView Filtering - CSV Style Data?
Mar 6, 2012DataGridView filtering. I have this data bound to a combobox:
Product Index
Prod1 1,2
Prod2 7,8,9
Prod3 10,11
Actual Table structure is:
Index Product
1 prod1
2 prod1
7 prod2
8 prod2
9 prod2
10 prod2
11 prod3
(Product is the Display Member, Index is the ValueMember)
On the combobox's SelectedIndexChanged event, I'm filtering the DataGridView:
DGVCustomers.DataSource.DefaultView.RowFilter = "indexes like '%" + MyDropDown.SelectedValue + "%'"
If MyDropDown.SelectedValue is "1,2" then any record without either number will not be shown , in addition "7,8,9" will only show customers with that string... etc etc. How can I filter the DGV correctly with the CSV style data? (It's not my data unfortunately!)

VS 2008 Filtering Data Before Output
May 2, 2011I am pulling different information from the same file at two different times: 1) The first time, I pull information that is inserted into a combobox. I need to use the combobox as a filter for when I pull the information a second time. 2) I pull different information from the same file, and it is outputted into a datagridview table. I already have a filter in place when the information is pulled the second time, and I was wondering if I could add to that filter or if I have to make another filter? The filter (or filters) will be used to filter the information in the datagridview before it is outputted in a chart.
This is the code for binding the combobox to the information

"data source='" & strFileName & "';" & _

Now I need to pick certain strings out of the rather large amount of text data and have the lines stored in variables, but the trick of it is, the exact string is unknown. The exact function should be, that the code finds certain tags from the source code, say <td> and </td> and takes the string data in between those tags, what ever it may be.
