Perform An Action That Requires A Http Request That Takes Around 5 Seconds?
Oct 14, 2010
Say you wanted to set a status message
' Set status
ssMainMessages.Text = msgValidating
Then perform an action that requires a http request that takes around 5 seconds then you want to display the result of that
' Set status
ssMainMessages.Text = msgValidated
It will only always display the second message? Its like it jumps the first part of the code and goes straight to httprequest.even if you put the update,system,threading.thread.sleep ....

Basically, It is a program that allows you to automatically click things.
Here is the
Public Class Form1
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer
[Code].....
What I wanted to do was make an option to have variations in tick time. I want to put in a check box, and if it is checked then there will be 10 "variations" in click time, ranging from 1 second too soon, to 1 second late.

I run a simple SELECT (noted below) in a stored procedure of a table that's around 1,500 rows.
[Code]...
This operation takes around 7 seconds. I inserted Breakpoints and used F11 to determine that upon MySqlAdapter.Fill is where the lag starts. Both my computer and the server hosting the MySQL database are NOT challenged spec wise. I'm guessing it's the query itself. collectionitem holds the 2 foreign keys linking an itemproperty to a collection. we feed the sproc sId(PK of collection) so that the subquery returns all the itemids from a specific collection and then we use the itemid(PK) in itemproperty. Is there any way to speed up the process?
UPDATE My issue was entirely due to improper indexing. Once I learned which columns to index, everything is extremely smooth!

I have an issue with a third-party COM+ DLL meant to be used from VB6, where it has a function to set a Callback for a hardware event. However, I'm using VB.NET, and AddressOf now returns a reference type instead of an integral type, which means that the setCallback function on the COM+ DLL apparently can't be used.

I'm using VS2010, SQL2008 and using asp.net vb - im stuggling with some db related items.I have a couple tables, Project and Projectstatus - looking something like this.project
- ProjectID (autoincrement)
- ProjectName varchar50
- Projectoverview varchar200
Projectstatus
- statusID (autoincrement)
- projectID varchar50
- projectstatus varchar200
What id like to happen is that when i create a new project (into the project table),that a row is created in the projectstatus table, inserting the projectID from the project status for reference.I don't think this can be done from within VS, correct? therefore, do i need to create a SP to perform this action from DB side?

I'm using ASP.NET/VB.NET to create this with SQL 2005. I have a project where I'd like to take a set of records from a table, then send each one through an API, get a result and writeback the result to a table, then move to the next.
Initially, my thought was create a SQLDataSource that grabs all the records, then perform the action on a button to do the action of sending through each record.
Is there a way I can call the recordset from SQLDataSource and perform a loop? I'm thinking something like in Classic ASP/VBScript where you would open a RecordSet, do an action, then Loop until the RS was EoF.

I've been using VB for exactly a week today and for that past 4 hours I've been pulling my hair out! My problem is that our software can only run on one PC on a site, if two instances are running they cause issues. So instead of checking each PC individually I created a program with VB to do this (and other tasks) for me. The problem with the network search is that if I cannot access a remote PC (usually access is denied) then it hangs for a long time before moving on to the next. Can I introduce a timeout feature where the program tries to access the c drive but if it does this for more than 5 seconds and gets nowhere then it moves on? [code]'testcpath' is \pcnamec$ and the other two paths look for the software I'd need to remove if found. So basically, if I have access to every c drive it works fine and completes within a few minutes. If I don't have access to even a small amount then it takes an absolute age.

I'm attempting to update a legacy VB6 component (not written by me) to the .NET platform. There is one function which posts an XML string to a URL:
Function PostToUrl(ByRef psUrl, ByRef psData, Byref psResponseText, ByRef psErrorMsg, ByRef psUsername, ByRef psPassword)
On Error Resume Next
Dim objWinHTTP
[CODE]...
I've updated this to:
Public Function PostXml(ByVal XML As String) As Boolean
Try
Dim URL As String = My.Settings.NTSPostURL
'TODO: supply username and password! '
[CODE]...
However when I run the .NET code the server returns the error '403 Forbidden - protocol error' on the line: Using Response As HttpWebResponse = DirectCas (HTTPRequest.GetResponse(), HttpWebResponse). The VB6 code runs fine. identify any discrepancies between the two that might be causing this?

I have a WinForms DataGridView control on a form. There are two fields in this DataGridControl:
Email Address
Resolved Email Address (calculated based on the input in Email Address)
After the user inputs or changes a value in Email Address, I want the value in Resolved Email Address to update based on a separate method. What event should I tie in to so that that the Resolved Email Address cell is updated after the Email Address cell is updated?I'm not sure where to put the event because the user could do a number of things after adding/changing a value: tab to the next cell, click cancel on the form, click ok on the form, etc.

I'm new to VB and Windows programming but I do have a fair amount of experience programming at the command line level. A friend is having problems with his laptop. He does a lot of speaking engagements with Powerpoint. His laptop uses the F7 key to toggle the output to his external monitor port to the video projector. The F7 key has stopped doing this. Is there a way to create a Windows program that will do this without using a DOS window? He is not familiar with command line processing and needs something that he can double-click.

Is there any way we could get directly say the 1000 characters after the first 5000 characters, skipping everything before that after sending in an HTTP request to an HTTPS page using either GET or POST in VB.NET? The reason why I ask this question is because in one of the webpage I am trying the get through my program, the website is sending response data in chunks with the first chunk containing some javascript garbage that I have no interest in, the only data I care is in the second chunk and
how to get the second chunk after receiving the first one since it is within the same HTTP request.It would save some time and Internet traffic if I can skip the first chunk that I do not need.Is that possible or I am just day dreaming?
ADDED: Here is how a typical header of the response I am getting from the webpage I am trying to get:
Date: Mon, 20 Jun 2011 13:21:56 GMT
Set-Cookie: JSESSIONID=1AF1AF9EF936E1CB2FA85B750EDC67C4; Path=****some path******; Secure
Content-Type: text/html; charset=ISO-8859-1[code].....
Not sure if that helps, but as you can see, the chunk size is not visible to me, there is no "Trailer" in the header as well.
