I have used mshflexgrid for my vb.net program. But it shows error when I try to build because vb.net doesnt support mshflexgrid. Please check my code & tell me what should I do to do same thing there in datagridview? Datagridview doesnt support same code. So would you please tell me what should I write for it?

I have a set of textbox's 0-8 each has a label as textbx0 to textbx8. What I need to do is perform something like this:
for z = 0 to 8
result(z) = a + b
textbx(z).text = result
I know this is not complete.I need to write a result to each textbox0-8. I can do this 1 statement at a time, is there an easier way using for, do or while loops?
My code looks very similar to this post Read bytes from NetworkStream (Hangs), which I copied below. ( I realize this is c# - I need a vb solution)
[Code]...
My issue lies in this:
I have a form that takes user input on which tif file(s) to find (which ends up being the getBytes(message) ). When one does this, it always returns one result - the first tif file that fits the criteria, However, I know in certain instances I should recieve more than one match.
Then I send the results to a picturebox and should be able to scroll through results (which this part works fine)I've tried a few ways to get multiple results, but maybe I'm missing the obvious? My best guess is using the asyncronous beginread/write.I've attempted using a for loop but I end up getting a bunch of the same tif files as a result..
I have a for xml raw select query that returns a xml string in server2005 and i would like to write that string to a file using vb.net.
View 2 RepliesI have a gridview with two cells cell(0) is a IP-number and cell(1) is a resultTxt. I have X number of rows. I want a solution that check each row and do a ping to the ip and write result to result. I want to do the ping in a new thread and i want to be able to do more then one at the time. So I want a loop that keeps checking the ones that are not online until they goes online. It's the thread-part I have questions about, looping gridview and doing a ping I can manage, but it I don't do it in a thread the interface freezes.

I'm filling a DtatagridView as usual, using a datatable as datasource and I have the SelectionMode = FullRowSelect, but since I need to color each row according to its result, I have set the property DefaultCellStyle - SelectionBackColor = Transparent, well, I'm not going to complaint about the font looks a little bit distorted, but about the selectedrow does not render correctly, If I minimize the program and then maximize it, the selectedrow appears with the image of the desktop's background.

I want to make a search form the user completes the 3 textboxes and 2 datetimepickers. (so five components).
Also I have a button called search and a datagridview.
When the user presses the search button it searches into those 2 tables (depending on what user typed in the 3 textboxes and selected on 2 datetimepickers).
Example of search:
The user searches like this:
When it presses the search button the results will be stored in datagridview(first textbox is the field DB-20-RTS from table PatrimoniuMasini and the rest are fields from the specified columns (name of labels) from the second table FoaieParcursMasina -is the second row from this second table).
Here's the code in my search button (don't know how I can store the 5 things(2 datetimepickers and 3 textboxes in the DataGridView) . My problem is in understanding the property item of DataGridView(DataGridView1):

I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

View 2 RepliesI am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:
Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:

Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)
I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?

How to write data From DataGridView to RichTextBox

I am using MS Access 2003 and vb.net to develop a windows application of inventory management.
I have used datagridview in the form and using FillBytoolstrip option, can filter data using type.
But i have no idea as to how can i update the database to reflect the latest changes in the gridview.
following is the code I have used.

I have 2 tables:tblcode and tbltransaction tblCode with 2 fields:Code and Description with data like
Code Description
A test1
B test2
C test3
and tbltransaction with 4 fields:transactionID,UniqueID,Code,Value with data liketransactionID and UniqueID are the primary keys)
transactionID UniqueID Code Value
120 1 A 0
120 1 B 1
I want to write a query that outputs:
transactionID UniqueID test1 test2 test3
120 1 0 1 0
so because tblcode has 3 fields I have 3 columns which are test1, test2 and test3(the descriptions of Code A,B and C) i tried to use pivots but it didn't work for me since I don't know in advance the number of rows in tblcode?
