View 1 RepliesThis is a homework assignment, but i want help, not answers. I made the form for this project, but my instructor supplied the code, the problem is, it doesnt work haha I have been trying to troubleshoot this for the past couple of hours but my problem is that when it comes to VB, my major weakness is database connections. When i run the code the form does not pull any data as it is suppose to. My thought is that it might be outdated because the instructions i got told me to "open Visual Studio 2005" so i dont know if the VB code from 2005 to now has changed? I have VS 2010 and SQL server 2008 R2. My first thought was that maybe my connection string was wrong, but i put in the same information that i use to connect in sql server management studio and i read that if the connection string was wrong VB would throw an error, is that right? With all the code entered in VS, it doesnt show any errors such as syntax errors etc.
It does error out when i run the program though, im guessing because when i click update, or edit, it cant because there is no data in there to edit or update. I'm wondering if someone could review this code and tell me why it isnt pulling data and explain it to me so i can understand. I will attach my whole project instead of pasting the 500 some lines of code.

I have a text file that is going to store some data in this current project. Instead of having it stored on a location on the PC (like C:Test.txt) - I wanted it to be a .txt resource of the application.Using a streamwriter isn't working when I'm attempting to write to the file. This following code runs without error however when I exit the application and look at the text resource file it remains blank instead of showing "Testing".
Dim Writer As New System.IO.StreamWriter(My.Resource.TXTRESOURCE)
Writer.WriteLine("Testing")
Writer.close()
I would like to know how to write to a text file that is added to resources and then have it show the contents in a text box.But I would like to have it on a timer so every second it will refresh as I am trying to make an instant chat program.Also I would like to note that I want it to delete everything after all the users have closed the program. Is there any way to make it so the text file is empty when there is no body using the program any more?
Public Class Form1
Private Sub btnSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click

View 1 RepliesI should start a project where several clients are included. There is a wcf web service controler that after a call from an specific client about a certain question it will retrive data from a server in London and then it will pass it back to the corresponding client in a different country e.g.
Clients and service are far away. the only way of transportation is through HTTP and intenet connection. Service should be able to callback also so i guess it will be dualHttpBinding.
I am trying to simulate human temperature taking. Basic I just need a button, a textbox , a progress bar and a timer. What I want to do is that when the button is clicked, the progress bar will slowly increment and after it reaches maximum, a random number in the range 35-40 will be generated in the text box.
Now so far, this is what I've done:
Public Class Health
Private Sub Health_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Start()
[Code] .....
So this is suppose to be a temperature gadget for kids and therefore when a certain amount of temperature is reached...an alarm is sent to the parents. So the progress bar is working fine. The random number generator too. A "sent" dialog box is open if the temperature is >38.
1-The number is working. But I would like the number to b e generated AFTER the progress bar reaches maximum.
2-The sent dialog box is open basically the moment I click on the button to start the progress bar (if the num generated is>38). And it keeps up looping and opening.
I have ASN.1 format files. I have to convert into CSV(comma separated) format also readable one. Tell me the shortest way... Like Decoders etc.

I am currently debugging throught a lengthy piece of code that behaves differently if the batch loaded is created from one way or another. I have tried going through it and it seems each step is the same, so my question is, Is there a tool that will record each line of code that is hit while debugging? so instead of writing everything down and risk missing something i could just run the program use beyond compare to compare the results of both runs.

View 1 RepliesI need to refer to some strings using an "indirect string" in the registry. It should be in this form:
@filename,resource
MSDN: "If the resource value is zero or greater, the number becomes the index of the string in the binary file. If the number is negative, it becomes a resource ID."How can I find out either of these numbers for my resources that only have names in VB? I also need the ID/index for the exe's icon.
I would like to know what are the basic steps involved in setting up your application to able to read data from another application.

View 1 RepliesI am relatively new to the world of programming and I was wondering if anybody could help me with a small project. I am trying to create two programs in VB.Net that each do one of the following individual actions:Find the average grade given several user-inputted scores on assignments. The program should also provide the following feedback according to the final score (i.e. A, B, C, D, F).Run two separate threads printing numbers (or words) in ascending and descending orders. (The numbers (or words) should be given by the user.)I have a basic understanding of VB.Net, but I am having trouble when it comes to creating even remotely complex programs. I have a few ideas on how I may go about these, such as using an arraylist for the first question that takes user input to find the grades, and then uses a series of If-Then-Else statements to display the letter grade, and possibly using steps simply with dual threading that would result in numerical order being printed in ascending order and descending order.
View 1 RepliesI have code that runs a deal.deal is a series of conditional steps [e.g., pay Fee1 from Account2 if (Variable5 > 500, Variable5 / 2, 0)].
These conditional steps are stored as strings in an access database.The conditional part can be extremely complex.
What is the best way to get my code to understand the conditional part?Do have to write some huge parser?
Is there a function that can do this for me(something similar to application.evaluation function in VBA)?Or do I need to approach this in an entirely different way?

View 3 RepliesGreetings, I'm looking for a way to encode a string into HTML that uses human-readable tags such as ê (=ê). At the moment, I am using the HttpUtility.HtmlEncode() function, but it appears to return numbered tags instead of human-readable ones. For example:
Dim str as string = HttpUtility;HtmlEncode("vente - en-tête")
'Expected: vente - en-tête
'Actually received: vente - en-tête
Is there a setting or function in ASP.Net to encode a string into HTML resembling the first comment?
EDIT: I am looking for this kind of functionality because the text is saved HTML-encoded in the database. The text comes from a bunch of MS Word documents that have been converted to HTML.
I have USB device that is detected as human interface device (HID). The device has one button on it. I want to have more of same devices attached to one PC. I would like to simulate a click on that device (it is not a mouse!). It should be simple using Windows API, but I just can't seem to find an example or at least function that does that (I successfully found code that takes position of a MOUSE, and sends click to a MOUSE, but I need that for my HID). What i really need is an example how to simulate click on HID (something like joystick).Second question is a bit more complicated and I can't find a solution. The HID when button is clicked returns data (5-6 bytes). But data returned is immediately printed to the screen (like i typed it on keyboard) and it is followed by CR, however no data is left on clipboard. I don't know how to get that data to my program. Detecting keystrokes using Windows API (something like keylogger), or to make a control (richtextbox) and retrieve data from that control? Thou important notice is that my program is complicated, involves multithreading (cross-thread operations are a mess) and is TIME CRITICAL (as much as it can be on Windows - you get what I mean), so cross-thread access of control will slow me down a lot or even just won't work. Something like this:[code]Even if this problem is solved it still makes it buggy because user should be able to use GUI all the time.

This is weird. I have a class that inherits from IEnumrable whose Count property is reporting 0 (zero) elements but the For Each loop steps into the loop body and tries to use the variable where it should just be moving on. My code:
On Error Resume Next
Dim d As Foo
For Each d In fooCollection
' use d and throws an exception
Next d
Weirder still, every time d is accessed i get an exception thrown in the output window:
A first chance exception of type 'System.NullReferenceException'
but i'm not stopping on the exception (not in a try/catch block).Is "On Error Resume Next" causing this weirdness?
Weirdness found:Per Rowland's and JohnH's comments i checked the Foo class:The GetEnumerator method inside of Foo didn't actually return anything! It had an empty body. That coupled with the On Error Resume Next before the loop caused the havoc! Wow this was ugly.
