View 2 RepliesI have a Form with a Tab control on it, one of the fields is the Apartment number which is a Combobox. It is displaying properly, however since it sits on one of the tabs when you scroll through the records its hard to remember what tenant you are dealing with.
I have a label on the top of the screen that shows the Tenant First/Last Name.
I also want to at what Apartment Number they are looking at.
I currently am trying this: I have also tried:
SelectedItem
SelectedText
SelectedValue
Column 0 of my combobox is the ID and Column 1 is the Text description.

View 1 RepliesI have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.

View 2 RepliesI have properly configure the database connection. I wanted to get data from the database to 2 text boxes.

1. user writes he's details (textbox1 for username, textbox2 for password)
2. user hits "Login"
3. application tries to retrive data from sql server. (in this case localhost/127.0.0.1)
4. application retrieves data from test/tables/members
5. if the specified account information matches the servers data, it will let you through to the next form. Else, it will give an error that the user/pass is incorrect.
Now look, the table looks like this
[id] | [username] | [password]
1 username password

View 5 RepliesI am retrieving data from a csv/txt file using oledb driver
ConnString = "Provider=Microsoft.Jet.OleDb.4.0; Data Source = " & System.IO.Path.GetDirectoryName(strFileName) & "; Extended Properties = ""Text;HDR=YES;FMT=Delimited"""
strQuery = "SELECT * FROM [" & System.IO.Path.GetFileName(strFileName) & "]"
In the last line I am getting following error if the filename is large
Is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long.
My question -
Is there any limit to filename or the select query or there is some pattern which I need to follow?
