VS 2008 - Dynamically Direct Control Event To Use Predefined Method
Nov 15, 2009Is it possible to dynamically direct a particular control's event to use a predefined method. For example: I have a form which I dynamically add controls to, let's say, TextBox1, TextBox2 and extBox3 and a module which as 3 routines, Method1, Method2, Method3. When I dynamically add my controls, eg TextBox4, I want to choose which of the 3 methods I want mapped to which event.
I was thinking of something like this...
Dim objTextBox1 as new TextBox
dim NameOfRoutine$="Module.Method2"
Form.Controls.Add(objTextBox1)
Call AssignMethodToEvent(objTextBox1.GotFocus, NameOfRoutine$)
Communication Via Serial To USB Cable
Jun 24, 2009I have a device that communicates with the pc via a serial to usb cable. So I have made windows form with a serial communication to speak with it. The communication is every 125ms so every time it checks if the com port is open and sends the new message. The problem is that if the usb is not connected the program tries every 125 ms to connect to the serial port and the busy cursor appears always and the form is not responding to any action (for example enter into the menu or refresh a listbox). I have tried multiple times to connect and disconnect the usb while the program is running. That's mean that the serial connection stopped and started all over again several time. The problem is that occasionally it shows an error "unable to open com port".

Oct 28, 2010So I am trying to get info from a scale using an RS232 cable into a VB2010 program. But before we even start talking about that, I don't know ANYTHING about serial ports. I need to learn how to get the data from the scale without programming first... I am using Win7. I do have a sample program (w/ source) I downloaded [URL]) It runs without any errors, then I have a big USER error, what do I push? How do I tinker to figure out the right settings on this interface? or any interface.

View 9 RepliesCommunications :: Serial Port Communication Via Null Modem Cable?
Sep 4, 2009I have a VB.net app running on one computer, displaying text into 2 texboxes or labels.I need to see the two values in two sperate textboxes or labels from the two labels on another computer via a null modem serial adapter.
1st computer.
Code:
serialport1.writeline(label1.txt)
straight forward right?
2nd computer to read the data
Code:
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
dim s as new string = serialport1.readline()
label1.text = s
This is what I was thinking;
Code:
serialport.writeline(label1.text & label2.text
This would send the two values over the serial port. How would I seperate the two values and display them in two different texboxes?cannot use them together)Am I on the right path at all? Or using the serialport.writeline method won't work at all....

VS 2008 Combining Projects Into A Solution?
Apr 6, 2011As far as I know , it is possible to combine projects into a solution . So , lets say we have 3 projects . Each project has a starting form , lets call them SF1 , SF2 and SF3 .What I would like to ask you is how can I write code in order to have both the solution and the partial projects , working . You see , the solution (which as far as I know will also be accompanied by a new project) has to have a starting form ; lets call it SF0 .A) First of all I'd like to know how can I call a partial project from the solution itself .B) What code do I have to write in the partial projects in order to keep them running correctly when they are separate (that is not part of the solution) . I am asking this question too , because as I guess , there has to be code in SF1 , SF2 and SF3 (into buttons) that lead back to SF0 , but

IDE :: 2008 Solution Explorer Focus Colors
Mar 27, 2009In the Solution Explorer window, is it possible to change the highlight color of selected items *when the form does not have focus*?For example, selecting a module in the Solution Explorer highlights that module's name in Blue, then when the focus is lost by moving to another window in the IDE, that blue highlight becomes a very, very light gray (on some LCD monitors in particular). I'd like to make that light gray a bit easier to see.Is this possible? I'm running VS2008 SP1 on Vista 64.
View 2 RepliesVS 2008 - Build Must Be Stopped Before Solution Can Be Closed
May 20, 2011When the Visual Basic compiler (Vbc.exe) crashes, Visual Studio fails to detect this and becomes stuck in an inoperable state. The "Build" menu appears as it would if the solution were building, but the Cancel Build (Ctrl+Break) menu item has no effect. Trying to close the application or the solution gives the error:
"The build must be stopped before the solution can be closed."
I can't find any way to remedy this short of terminating the devenv.exe process and restarting Visual Studio completely. Is there anything quicker and less severe?
VS 2008 Meaning Of Icon In Solution Explorer
Oct 6, 2010Some of my students end up with a different icon in the Solution Explorer when they create applications. An example is the attached Exam.vb icon, which includes a little arrow into the normal Form icon (see pic) . I am guessing it means it is linked some how. When the application is zipped and submitted, an error is thrown when I unzip it to grade it which indicates that the file in not part of the project, and it references the absolute address on the original application.Any idea what caused this and how can I instruct the students to avoid it in the future?
