I populate s combobox like this:
Private dbpath As String = My.Settings.SISQL2ConnectionString
Private con As New SqlConnection(dbpath)
[code]....
when I select an item from the combo i need to pass the ProductID to another sub.
For the application I am making, I want a unique identifier (a weak one is fine, just something that would hopefully tell two computers apart). I think I found the right value for the job in the registry, but for some reason it does not want to read intothe program am going after the following key:HKEY_LOCAL_MACHINESOFTWAREMICROSOFTWINDOWS NTCURRENTVERSION ----> ProductIDThe code I am using to attempt to do this is as such:My.computer.registry.getvalue("HKEY_LOCAL_MACHINESOFTWAREMICROSOFTWINDOWS TCURRENTVERSION","ProductID","x") (that last one is just because I need to return some sort of string)However..... I only ever get X returned, and I'm not sure as to why. I tested this with other keys in LOCAL_MACHINE in case it was somehow protected and they worked
View 11 RepliesI have a string " ProductId + "&" + lblDelegateName.Text + "&" + lblMasterCustomerId.Text + "&" + lblUserName.Text". I want to split the string so, I can get the productId and the lblMasterCustomerId.text. Then, the lblMasterCustomerId.text again contains 16 or 24 digits. I want to split the digits so, in the for loop I can get the first 8 digits and next time the next 8 digits and then, the last 8 digits.
View 4 Repliesim tryin to link the 2 pages to each another, 1st, when i click on the View hyperlink in the product page, its supposed to lead me to the product view page, with the product chosen being displayed. Ive searched the net, and well, ive found some solution on this, but most of them were to update the statements, for my case it would be just to lead from the product page to the product view page. But everytime i press the view link, it leads to an error.
The source code is as below

I have a datatable which contains a column (ProductName) and it has 10 rows (products). This number of rows in this table varies.The database table (Products) contains 2 columns (ProductID and ProductName). Is there a way to retrieve the ProductID and ProductName from the database table Products by using the datatable instead of creating a one big SQL statement using WHERE clause using?

tc_1 001 pass
tc_1 002 pass

tc_2 001 pass
tc_2 002 fail
tc_2 003 pass
table2"
case_no result
tc_1 pass
tc_2 fail
Table2 should be updates from table based on the results... If all results is PASS then the table2 should be updated as pass... if any result is FAIL then the entire case_no should be updates a s fail..
Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController
