I am looking for some input. I am helping with a web application that is fairly large. We have some logic factored out into classes, not a true business logic layer (yet ). The classes are setup to pull values directly from the QueryString or Session variables and I'm not sure that that mehtod is proper or even a
The reason I would like some input is, there may be a chance to rewrite or at least refactor the code.

I have two tables:
table1
case_no flow result
tc_1 001 pass
tc_1 002 pass
tc_1 003 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..
This code was working consistently, but now...This code works on the first pass.Then second pass it just hangs on Code:Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() for about 2 minutesThen the code will fork for another pass, then 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

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
I have a sub that I want to receive a My.Settings object. I don't know, though, which kind of object to use in the declare line of the sub. For example:[code]
View 3 RepliesHere's the situation. Due to the design of the database I have to work with, I need to write a stored procedure in such a way that I can pass in the name of the table to be queried against if at all possible. The program in question does its processing by jobs, and each job gets its own table created in the database, IE table-jobid1, table-jobid2, table-jobid3, etc. Unfortunately, there's nothing I can do about this design - I'm stuck with it.
However, now, I need to do data mining against these individualized tables. I'd like to avoid doing the SQL in the code files at all costs if possible. Ideally, I'd like to have a stored procedure similar to:

I currently need to build a Automation Add-in for Excel. This add-in will load a recordset from Database to Excel. I would like to have function A() that I input in Cell as a formular. This function A() call a the add-in to load the data from Database to Excel. The data should be a matrix. So that means I would like to set in Excel worksheet a range of data by just calling single function in a cell. (I am sure there should be some way to implement it)As I know if I develop a shared Add-in by VB(or VB.Net) and in the add-in, I can get an Object of Excel.Application. By this Excel.Application object, I can get full control of Excel inside the Add-in. That means if I define a sub that load datamatrix from database and using the Excel.Application object I can populate the data matrix to the Excel.
I have done much research on internet and I now have built a shared Add-in for excel. I should say this add-in works fine without invoke the Excel.Application Object that I have tested. But when I call the Add-in function that invode Excel.Application Object from Excel I got an error as below:

ok to start i know very little about VB6 but i am very good in true basic lol (stupid school teaching the wrong language -_-) anyway im just asking you to make the answer as clear as possible because i don't know very much. heres the problem . ok in the above example i have a button that (for my example) can be used to build a house (lol) i then have a variable in the button sub called money which will have 150 subtracted from it when the button is clicked my problem is it say variable not defined when using this button ... i have declared the variable in a module and in form load along with my other 50 or so variables. my question is how do i pass the variable into this sub and then send the new value back into form load so it can be sent into another sub for more calculations.

I have the following sub which works for the type "Button". I would like to make it general by having a parameter that is assigned a type rather than "Button" being hard wired. Can this be done? How do you pass a type? I tried the parameter "ByVal t as Type" but the compiler complained when I used t as a type and I also tried inserting (Of T)but the compiler complained about CType(control,T).
how add type as an input to this sub?
Public Shared Sub Example(ctrl As Control, items As ToolStripItemCollection)
For Each control As Control In ctrl.Controls
If TypeOf control Is Button Then
Dim butt As Button = CType(control, Button)

I want to know what the best practice is for passing values (sometimes multiple values) between two asp.net pages
In the past I have used query strings to pass a value in asp like this:
href='<%# Eval("TestID","../Net/TestPage.aspx?TestID={0}") %>'><%#Eval("Title")%> </a>
I assume you can do this in the code behind but I do not know the best way.
I also assume it is possible to pass more than one value.
Assuming that I have a datagridview or a listview populated by value (form 1), then here I have a command button to edit (form 2, details in text boxes) a selected record from the grid or listview, now, the edit process is done, how can I then, pass these values to datagridview from the other form (form 1) and update or refresh the grid then close the form 2 as if it is not been opened?
