What is the best way of displaying database on a form? I have access database with multiple tables, and I want to combine them on a single form. Also, I would would want users to enter in a more detailed view of a particular row. Is there any tutorial for this? What would be the best control to use for this?

View 2 RepliesSo my program is supposed to lookup the image name from a database and display it in the form. Here's the
name = rs.Fields("image").Value.ToString
If Not IsDBNull(rs.Fields("image").Value) Then
If rs.Fields("image").Value = "" Then
Else
PictureBox2.Image = Image.FromFile("\MY.IP.ADDRESS.HEREwwwrootimagesproducts" & name & "")
End If
[Code]...
Now here is the problem: If the database returns the image name but the image cannot be found in the path specified, the app crashes. Is there a way to write an If statement to check if the image file exists in the directory specified?

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()
[code]....
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 am facing a problem displaying the records of my table on the visual basic form I have created.
This is my code :

View 6 RepliesI have been staring at a blank screen for over an hour trying to figure out the best way to build this app. We have a warehouse with consumables. These consumables are stored on racks that are three rows high and 15 columns long. I need to display the contents of these racks with the following; Item nameUnit quantityUnit expiration date
Now while this in itself would be a simple thing, I need to . Take a look at this image, the lower portion of the image shows basically what I want to display as far as the form goes. Instead of the "Row 1-1-1" text, I want to show the item, qty and exp. There are multiple rows. It should also be noted that each location may have more than one item stored in it, and there might not be anything stored in it. So I guess my question is, from a design point, is it better to create a small table for each location and then join those tables to a main "Row" table since there will only be a single row displayed on the form at a time? How would it be possible to keep the data properly ordered from a coding perspective? How can I ensure that each storage location remains static unless the item is moved?
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.

View 1 RepliesI have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.
Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.
The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form.

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.
