I have a program that is connecting to an oracle database. I am using the table adapter to fill a combobox to select a model. Then I am connecting to the database programically to return a max and min value based on the selected model. I am doing this by passing parameters back with the selected mode. This all works fine. Here is my problem:

View 5 RepliesI have an access query which plays flawlesly in Access.I want to use it as a source for a datagridview i use in one of my forms but....given the fact that is a rather big query with some "like" and conditions like ">3" and so on AND the fact it uses tables from 3 different mdb (not to mention is bases on other queries...i 'ill try my best to fix this) what is the best approach .
1st case .Can i retrieve the data simply with NO oledbparameteres and NO " select * xxx where yyy like 'd' ".I think there is a issue with the Oledb connection that "omits" them.To explain better the query right now with the filters in access returns 3 rows, without the filters 30 rows,can i get just the 3 rows to do my job... 2nd case . How should i fill a datagridview using tables from 3 different mdbs.If you can show me an example it would be life saving.
I'm fairly new to VB.NET but have been programming for a while. Anyway, for the life of me I can't figure out how to properly populate a datagridview in .NET. I am using VS 2010. I add the control to the form, click the arrow on the control and select "add project data source". From there, I select Database, then Dataset, choose and ODBC data source, the table I want to use and enter the data set name.

I am working on a project that allows the user to search the database for particular records, then passes the record that the user chooses to the main form to be manipulated or changed. Yes I am aware that I could let the user change the values in the datagridview, but I do not wish to do that this way. This is the code for the event that fires when the user presses the button to return the selected row:
Private Sub returnBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles returnBtn.Click
Dim ActRow As ds.ActivityRow

DataGridView inserting an extra row every time I populate with data. The row appears even if I only fill the column headers. This is causing problems when I try to get values of each cell. Is there a way to avoid this perhaps in properties?
View 1 RepliesI have written some code in a form which is shown via ShowDialog from a different form. This code fills a DataGridView with data from two tables in a dataset, one through data binding, and one through more manual means. The latter part runs, or more accurately, fails to run in the same way if I call this form in the same way subsequently but without stopping debugging.

When the user double clicks on one cell of the selected row (of the datagridview) I want to open the second form and fill the textboxes with the equivalent data (I mean each textbox must be filled with the equivalent value of the selected record).

I'm working with datagridview.I found an example on the web about creating a datagridview: firs I make my array containing data, then I make a datatable from array, then I make datagridview from datatable.I don't know if it's the correct way but it seems work.In a column I make random numbers for test: for example I have on column "Time" these values: 1155, 1725, 584, 996, 1352.Then I try to sort with code when I press pushbutton: it doesn't work because I have the values:1155, 1352, 1725, 1758 (until now it seems to work correctly), but then I have 584 and 996 values: wrong!Ok, let's try with the manual sorting: same result.I filled cells with "integer" values, let's try using strings, then I used "value.tostring" same result.I also tryed to fill strings with blankspaces to obtain same length, but nothing changed. "1155", "1352", "1725", "1758", " 584", " 996".Then I tryed to fill with "0" values:"1155", "1352", "1725", "1758", "0584", "0996".The same.How can I fill cells values?

My problem in the Combo Box and SQL query .. I have three comboboxes linked to an Access 2007 database
[Code]...
I'm not 100% sure where to post this, as I'm making the program in VB.net, however It is linked to access and is getting the information / saving it into there.
I have a customers page and a jobsheet page,
the customers page is where the information on the customer is stored e.g. "Company" ,"First name" and "Last name".
When I Go into jobsheet, I have made it in so that company searches for the record from access so there is a list e.g. "Big W" , "Bunnings" etc, and tied up to the company is a name of the person in that company.
My question (after all the babble) is how can I make it so when I choose "Big W" from the list, it auto fills in the "First name" with 'John' and last name with 'Smith' , and if I choose Bunnings it uses the name associated with that and etc for the other companies.
Ok basically I want to select a point on a bitmap and then fill all of the color that is the same as the color at that point touching that color with a different color. If that sounds confusing, just think of the paint bucket tool in mspaint or photoshop. Currently I do this by starting with the point selected and then check all the points around it in an ever expanding box until at last no new contiguous points of the color to replace are found.The bad news: This is slow as heck =(I remember my windows 98 computer could handle this just fine with no noticeable delay. So I'm either missing something algorithmically (is there a better approach) or VB.net is just too slow to accomplish this without some sort of different approach/optimization.
[Code]...
As you can see, right now I just select the middle point as where I want to start filling from, and I fill with the color aquamarine. later I want to make this more flexible, but right now I just need this to be faster.
My general algorithm works like this:Start with a 3x3 pixel box with the first pixel (already changed to your new color, with the old color stored) as your start point.Check if each pixel is the color you stored (the one you're replacing) If it is, check if it's next to the new color you're replacing the old color with. If it is, replace it and increase the size of the box.The process ends when no new pixels are replaced.
i have a combo box that i'm trying to fill from a database, managed to get it working through the wizard and the form view method but could do the next bit that way. I then started to try it the coded way, got the database linked but it only shows the first name in the database, how do i get it to show all the names in the database?
this is the code for the form
Imports System.Data.OleDb
Public Class NewTicket
Dim ds As New DataSet

I'm trying to get a combo box to fill itself from a MS access database field but I can't get it to work. I can get it to work at school but not at home. Also can't get a program that worked at school to work here so I'm guessing that somewhere there is something blocking the connection to the database. I've gone into the MS access trust center and looked at the settings there but I can't see anything that would be stopping it. I just need to find that setting (if it is indeed a setting) wherever it is and fix it so that I can access my database. I am not using visual basic from access I am accessing access through visual basic.
I can't get it to work with an ADO connection, either. Also when preview data via clicking smart arrow on the combo box then going to preview data I can see the data just fine. Also I just noticed I get two lines in my output after the file is run that say "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" I don't get these lines if I comment out all the code for the combo box.
I am trying to fill a combo box using a dataset and data adapt. I am struggling too work out how to do it. I thought it would have been easy but I was wrong. i can set the text to read the first line of the colomn but nothing else. I was wondering if anyone could help me out with what I have to do. I think I have to increment inc and add a line underneath but I don't know how to do that
comboMaps.Text = datSet.Tables("TheLastShot").Rows(inc).Item("Maps")
I'm having trouble filling a ComboBox from a dataset. When the program runs, the combobox has the correct number of lines, but they all appear as System.Data.DataRowView.[code]

I have a combo box in a form, I want to fill it with names I have stored in a database.I know I have to use the fill command, but I am not sure what code I need to use.I imagine I need to place this code in the form load event, where I wrote my code to connect to the database.Tell me if I am wrong, but, do I need to create a sql fill command, select Names From Users, then execute that command in the combo box object.
