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.....

I have a .Net application (VB in particular, although I would this to be as language agnostic as possible) that uses a COM object (made in C++). I need to implement a event in COM that passes a char array from C++ to .Net. I guess I need to convert the array to a managed array; How can I do this?
View 2 RepliesI can't find a way to pass a simple variable from my code behind file to the .aspx page.
In code behind I have:
Dim test As String = "test"
and in my aspx page I try: <%=test %>
that gives me the following error: Error 2 'test' is not declared. It may be inaccessible due to its protection level
I created a DatePicker user control (ASP code below, no code behind) which is simply a textbox, image button, and a sometimes visible calendar.

Can I somehow tie or pass the value of the TextBox as the value of the whole control to use in the calling code? EDIT: My actual goal here is to be able to tie the SelectedDate as a parameter of a database query. I was able to select values for the other parameters in a controls dropdown list in a query parameter configuration window.

First of all; I'm completely new to VB.
Pass a string array from Visual Basic Express 2008 to unmanaged code in a Dll.The array is Dimmed as in DIM myArray(11) as String
I'm developing the dll myself using Powerbasic.
The dll expect a 4 bytes pointer to a safearray's handle. As far as I have understood it; the array's string elements must be passed in ANSI format. The code in the dll will then use OLE Api to get the LBound and Ubound of the array and the address of the first element in array.

Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window.
All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.
JavaScript Function
function RefreshParent(inputDate) {
window.opener.location = window.opener.location + "?Date=" + inputDate;

I am trying to create a application scripting environment for my VB .Net application. I have a form type in the application called Project. What I want to do is dynamically compile (i.e Eval) VB .Net code on a Project form. This dynamic code always has a Main function. One of the arguments to Main is a reference to the calling Project form. Here is the Eval code:
Public Function Eval(ByVal vbCode As String, ByRef MyAssembly As System.Reflection.Assembly, ByRef ProjectForm As Project) As ArrayList
Dim Provider As VBCodeProvider = CodeDomProvider.CreateProvider("VisualBasic")

I've been looking at accessing shared folders, read and write, via the network without being prompted by the OS for the username and password.
On this forum, and googling, I can find many things about accessing network shares, but none using code which also passes the username and password required.
What I'm basically looking for is to not have to map a drive on the users computer. Then using code, write or read files from a network share and at the same time pass the username / password required for that network share.
Right now I am using this code on client side.

The values for the hidden fields are already set. I want these value to open a window, in which the fields will be already filled using the values passed by this page. This code is working fine on Internet Explorer, but not on other browsers. Moreover, when I don't pass any value and just open the required window, it works on all browsers.
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..
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 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

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.
