I have been programming in VB6 for a while now and am switching over to .net. There are a few basic functions which I just can't get for some reason... I am forced at the moment to use a DAO/ADO connection, and I've been primarily using DAO in vb6, so I thought I'd carry this over to .net... atleast for the time being[code]...

I have a program in which I want to have the user enter two percentages and display the data matching the criteria on a new form. The query would be:
Select *
From Corrosion
Where corrpct1 >= {column in database} OR
corrpct2 >= {column in database}
The way I currently have it written is to display only one row of data. I need to display any number of rows that meet this criteria. My current code is:
Private Sub btnDetails_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDetails.Click
Dim form As New frmDetails()
Me.Hide()

1. How can I do my query to incorporate the user entered criteria (in the where statement)?
2. How can I display ALL of the data instead of just one line?

I need to quickly demonstrate a project and decided to create a user control that is connected to an Access database through pure simple data connections (create the dataset and drag it on the control.)When I build the project and add the usercontrol to panel control on the main form, no data is shown in the datagrid.When I add the data components directly on the main form, the data is displayed properly. why I can't get my databound user control to display the data on my main form?
View 2 RepliesI am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
DataGridView1.Columns.Add("CustName", "CustName")
DataGridView1.Columns.Add("Email", "Email")
[Code]...
I would like to know how I can make this happen?

I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.

I have an Address Book project with a listbox. The listbox is bound to the database via the little arrow pop-up box in the corner of the listbox.

View 4 RepliesI have a data set with a parent child relationship between a patient table and an insurance table. There can be up to 4 insurances for each patient. I want to display them in 4 separate panels of a vb.net form. So if a patient had 2 insurances, then txtName1.text on panel 1 would have the company name of the first insurance, txtName2.text on panel 2 would hold the company name of the second insurance, and so on.
How do I display only the insurances related to the current patient? I've tried moving through the rows of the related table, but that gives me all the rows, not the ones I need. Everything I see on the internet suggest using a datagrid, but that's not an option in this case.

Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
