DB/Reporting :: Retrieve Data From A Certain Row And Place In Textbox?
May 7, 2008
I have 10 IP address I need saved so that when the programed is closed the user doesn't have to re type them all back in. To get around this I created a database that would store the values. My table contains one Field "host" and then has all 10 IP addresses listed below that.I'm trying to figure out how to make a text box on my form look at a certain row in a SQLServer 2005 table.
For example:
txtIP1.text = Row 1 of SQL table
txtIP2.text = Row 2 of SQL table
Here is what I have in my Form load Event. This works, but again I need the second rows value to show in the second txtbox.

I have successfully added textboxes to a form at runtime. I have also succesfully added an event handler to these same textboxes. What I'm having trouble understanding is how to refer to these textboxes programmatically after they have been added. Specifically, how do I;
1) Retrieve user data entered in those textboxes without an event handler
2) Find a specific one of those textboxex later (is looping thru all controls of type "textbox" the only way)?
purpose of find is so that I can set the value of the corresponding textbox programatically, based on some criteria Here is the code (all within in a for loop, where intvararycount is incrementing to a set limit) I have used to add the Textboxes to a Panel on a Form;

Is it possible to have a quick and easy way of retrieving the last 10 records from a table?
Currently what I have been doing is retrieving all the records then one-by-one cylcing through each record until I have the last 10. To me this seems to have a lot of over-head reading each record. I just wondered if there was a quicker way of doing it.
I need to convert a large VB6 app to vb.net which does a lot of database work and produces a Crystal Report. The initial form is simple a login form which validates the user. I am trying to use a datareader to retrieve the user's login info but it won't compile on the statement where I'm trying to get the Connection String from the app.config file. It complains that the ConfigurationManager is not declared on the dim statement. Where and how do I declare the ConfigurationManager? I thought it was just pointing to the app.config file but apparently that is not correct. [Code]

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
I have this code inside am event in a combobox. Because I don't know the placement off the textbox before I have run the code in the combobox: Dim txttotal As TextBox txttotal = New TextBox txttotal.Name = "txttotal" txttotal.Location = New System.Drawing.Point(x4, y) txttotal.Size = New System.Drawing.Size(100, 15) txttotal.TextAlign = HorizontalAlignment.Right Me.TabPage3.Controls.Add(txttotal) I can see the textbox thats works fine. But in another event I will give txttotal a value But get the error txttotal not declared.
I'm having some problems with placing the date and time (e.g., 11/3/2011 10:13 AM) into a text box as I tried several things. The above date time format shows in properties as the value but when I try using it, the textbox shows "11/3/2011 12:00:00 AM). Any way to assign the date and time to a text box?
