Caller Display, Connect To Modem Just Like HyperTerminal?
Dec 12, 2010
i would like to build a very simple program that connects to my modem and outputs in grid format, caller display, date time etc etc.Ive done loads of searching and i've found a few examples online but most are for VB6 and ive spent ages trying to upgrade them but with no joy!I have found two enxaples that work with VB2010 but i have struggled to make them work and also they seem way too advanced for me to learn from.

I am doing a sms project using VB .net to connect to my gsm modem via serialport. All the connection and everything was working great and I can send and receive sms. Then here come a problem, I need to send long sms more than 160 chars. I read and did some research and I know that I need to use the pdu and udh. I managed to understand slightly of the pdu packet but is still quite confuse on that part.
Anyone can briefly explain the exact way to do the concatented sms (long sms)?Another problem is how can I use vb to encode the data into pdu gsm 7bit data? Is there any built in functions or do i need to write them myself?

I am attempting to call a remote modem using a local modem connected via USB. Programming language is VB.NET and I am using the SerialPort control to talk to the modem.
Communication is as follows:
I send: ATZ0[CR]
Modem responds: ATZ0[CR][CR][LF]OK[CR][LF]
I then try to dial a number:
I send: ATDTnnnnnnnnnn[CR] where nnnnnnnnnn is a valid number
The modem responds with:ATDTnnnnnnnnnn[CR][CR][LF]ERROR[CR][LF]
All other commands seem to work without any issues
For info the modem is a MultiTech MT5634ZBA-USB-V92
If I use hyperterminal and type the same commands in it works as expected and dials the number, so it must be something I am doing in my code, possible some setup in the SerialPort control

(from scratch as I've not done this before) how I can stream live through modem-to-modem connection. The modem here refers to dial-up modem (PSTN modem), there is no internet/lan involved.It will be 2 programs, the first is to transmit real-time video from webcam, and the second is to remote video from the first.

I am a ASP Classic Programmer, professionally for a little over a year, I have developed some rather nice sites, including the one in my signature (Still a work in progress).
I have been forced to use ASP.NET (VB) for a FileUpload control, as it offers a self controlled way of creating Thumbnails, without the use of 3rd party controls, which is great, as my hosting server does not allow for 3rd party installs on their servers.
So.
The code below is what I have so far for connecting to the database and displaying a record is the "cookie" exist on the users computer.
Unfortunantly, this is not working, and to be honest with you, their is not a whole lot of resources available to show how to do this correctly.
So I am stuck with a lot of post and hoping that someone can actually assist me with this and tell me what I am doing wrong and maybe correct my code.
I am getting an error about the "Connection is closed"
If you want to re-write my code, I prefer something simple and basic, as the only thing that I am doing to checking rather the user is logged in, and if so, display a record from the database. I am NOT in the need for the DataGrid, so please do not suggest it, as I am only needing to check this one thing.
I would like to also add, that I have successfully contect to my database with the FileUpload control and save file names of the images uploaded, so I know that my connection string is done properly> But, for some reason the "SELECT" statement is causing a HUGE issue. (It was easier to insert, than to select, I am not use to that)

I've written a series of ASP.NET pages which have several common methods among them. In my ignorance, the best way I was able to find to move those common methods to a separate file was in a Module. However, what I need is a way to identify from which page was the method called?For example, I have a method call WriteToErrorLog with the following signature:WriteToErrorLog(ByVal sender As Page, ByVal Source As String, ByVal Message As String, ByVal StackTrace As String)

I have 2 buttons that will open the same form. but depends on which button is calling, the operation will be different. How can I identify that this form is called from button 1 or 2.Also, if we want to have a password in the vb.net stand alone application, should we use shared property?

In the SignalR Chat sample, Caller properties are set using the code;
Caller.name = newUser.Name;
Then later on, this property is read;
string name = Caller.name;
I have my own SignalR project, but this one is vb.net, and when i do the same setting and getting of the Caller properties, it doesn't work
Public Sub SetCaller()
Caller.name = "tim"
End Sub

I am creating a class ("Class B") which is used by another class ("Class A") which instantiates it in VB.NET 3.5.I would like Class B to read a value assigned to one of its properties by Class A every time an event happens in Class B.However, I would like this property value to be dynamically assigned to the property by Class A when the event is fired in Class B.I was thinking about somehow creating a delegate function in Class A that is linked to the property in Class B so that when the event is fired in Class B it would eventually invoke the delegate in Class A so that it returns a value to Class B.I've been reading around delegates (that's how I arrived at the idea), but I am stuck on how to code this up - could someone please help with some skeleton code?

I have the following
Sub ChangeLanguage(ByVal caller As Object, ByVal lang As String)
Dim c As Control = caller.GetNextControl(caller, True)
Do Until c Is Nothing
[code].....
I call the sub with:
ChangeLanguage(Me, "en")
The problem I have is that I get the error: "Type 'caller' is not defined."If I change GetType(caller) to GetType(vbLogin) it works fine. (vbLogin is one of the forms)I need to find a way to get it working using caller though.

Even when i debug my own code, i'd find it a useful feature.In c++ this feature is default in visual studio(its called browse-something), but i havent found any such thing for VB.NET yet, any ideas?
