The second line will have numbers if other table has information about that customer reservations, or will be in 0 if not.I can load the first line of each pair, with the data of the "requested" items loading a datagrid with a datatable.
I am totally new to VB and ADO. I know that we can bind a data source to the datagrid view but if I want to populate the same datagrid view with different set of data but the column names are the same. Based on a date range entered by the user I would like to populate the datagrid view. Can we do this at design time? If I not how do I do this?

I am trying to fill a label with data, using datagridview, from a specific row, cell. The commented out code works but is tedious and sequential, basically has to go row by row. Is there a way I can just say "hey, gimmee the data at x,y?" LOL Trust me, at one point I even tried that. All this must take place at form load so there is no click events involved.

[code]....
Why does it only print all the rows for each DS (different sizes/colors) only if there are more then one DS? (if there is only 1 DS it will only print one row, regardless of different colors/sizes but if there is 2 DS, it will print all the values from the first DS)I have gotten a massive headache from trying to figure out these 2 problems. If any1 can help I would be very grateful. Please let me know if you need anymore info (SQL tables, data), and I'll put them up.

I am new(ish) to Visual Basic and i have learned from looking at old VB6 code for programs that have been made for us in the past, this includes using the old ADODB connections and FlexGrids which both have been changed in VB.Net to OLEDB and DataGridView.I have started to understand the way the connections and datasets etc are created but i am struggling to get to where i was with the old code (I am trying to completely upgrade the code from FlexGrid).This is the VB6 Code i am trying to upgrade from:

my problem now i guess is 2 fold, i wish to combine the first 3 queries into a single query and place in a list or a collection or is there a way to do this with a single query that will give me my desired result?
I have 2 tables that are related. Each app can relate to many apps. ie, office can be related to word, excel.[code]I would like to do the following query. I use vb.net but c# is ok.Query is to return all the apps that are not related to (1), so the result should be (4, quake) .
I am trying to fill a temporary table with one column( a code) with the unique results of three queries of their respective table adapters.I can't figure out how to do it from here.The database is Access 2007 and I have activated the appropriate dataset on the form from which this code executes. The table adapters are part of that dataset.I could try to use the recordset approach, but that means making another connection to the same database.Is that a preferable approach?My purpose in doing this is to build a VB process like the one that works in a VBA Module of this Accessdatabase, partly to help me learn VB2008 and partly to overcome the necessity to keep updating queries used by the module.Code below
I have a problem with sorting this thing. I want to sort a column without changing the data in the other column. i have an attached document. A picture of my query and database..
I am working on a Data Survey Project and first I have a few questions about the different types of databases, and second, I need help querying my tables that have relationships.
1. I need a database that is stand alone. It is just the back end for the program. Simply to hold all the data an employee gets while out on a job. So would I be better using access, or SQL Express? I have played with both, but I do not want a large redistribution to my user machines. When I compile and produce this app does the SQL Database still work without installing any SQL Technology? Or do they have to go in after they install my app, and install Express?
2.Overview: I suppose depending on the first question regarding the database, it might change this question a bit, but none the less...I have 4 tables( using Access at the moment) I will be generating Reports based on data in the database. I haven't gotten that far yet. *Project* is the table that holds all the details that pertain to the job and client. It has a "one-to-many" relationship to *Survey*. So for one customer there are going to be many Survey Records. *Project Type* also has a 1-to-many back to *Projects*. Parts is kind of an orphan, but is linked to the *Survey* table with a one to many. So there can be many parts for one survey. I wanted this table for a drop down box, so the user could just simply select what hardware he was using instead of typing all the names and parts.
So in VS 2008 using the Designers and related Query tools, how do I constrain the Survey Data to one Customer? I have one form that opens from a button that is "New Project" and then there are all the *project* fields listed, so the user fills out the info and hits accept and that opens a new form called "frmSurvey" I need to add some code to the accept button to check what type of project is selected from the frmNewProject and then run a select query based on that. How do I write query statements in the code section of the form, without using the Visual Database tools?
Ill stop here, and get these questions out of the way first. If I could just get a handle on how to use the data properly with different forms and different controls with my queries, that would be great.
I've got a couple of drop down lists for languages. I bind them to a language list that comes from a query. Then the fields are also bound to the row in the DB they relate to. I have several panels with the language drop down - each "tied" to a different table in my DB. When I call up different records on the same panel the drop downs immediately "set to the position" of that rows language in the list. But when I call up another panel - tied to another database table - I see that language in the drop down.
I am trying to fill my DataGridView using a date for my parameter. My first problem was in my code where I would get the common error message of Too many arguments to public overrides overloadable. I solved that error message by going into the dataset designer, selecting the query and adding RegDate as a parameter. Now my problem is that I will enter a date in my tool strip text box click the button and still get my data grid view filled with all the data.
Try Dim RegDate As Date = CDate(RegDateToolStripTextBox.Text) Me.PatientsTableAdapter.FillByDate(Me.Database1DataSet.Patients, RegDate)
I have a datagridview which I have set up with the Form Designer and created 2 columns and set header names and column widths. When I try and fill the datgridview instead of filling the columns I have created two additional columns are appended to the right of the existing ones and the additional ones are populated leaving thje ones I created blank.[code]...
I have database say xyz.accdb with a table called say details containing the fields (Name, ID, Comment & Status)I want to create a form with DataGridView and get all the details from the details table into the DataGridView though coding (i.e., DataSource should be from code rather than adding it to project).PBL (Visual Studio 2010 Ultimate)
