Communicate With Gprs Tracking Device Through Application?
Mar 11, 2010
I have a tracking device CT-04 car tracker that i am trying to integrate with my vb.net desktop application. I have the protocol from the manufacturer (redview) that contains the commands to send to the tracker unit and from tracker to the server. My application is in vb.net .
I wanted to know how i can send the commands from my vb application i.e can i still use vb.net to send these commands to the tracker through gprs?
what do i require in terms of hardware and software from my side in order to send these commands through gprs (not SMS ) to the tracker unit and to receive data from the unit.
I`m working on a project where i have connected a FPGA chip to the PCI bus but now i am trying to figure out how to communicate in VB to that device? Normally the device has memory assigned to it in XP (address h00000200 to h0000037F) but i don`t know how to read/Write to that memory directly in VB...
I use visual basic. net, I would like to communicate with a device via COM1. Sending a command in the HEX format for example 02 00 05 15 ... and take the device to respond in HEX format. these commands I found on the Internet.
Private Sub Button1_Click () Handles Button1.Click
MSComm1.CommPort = 1 'Use the COM1 serial port MSComm1.Settings = "4800, N, 8.1"[code].....
I bol pioneer of this program looking at Google, but I was never clear. meetings drgač this would be doing, but the service not to a significant'd be best if someone had already written CODO. better, but also that we already sent someone made programs
I'm using VB 2010 Express with a local Access DB. On the form I have a DataSet, a TableAdapter, a BindingSource that points to the DataSet (and the DataMember is the same table as the TableAdapter), a BindingNavigator that points to the BindingSource and finally a DataGridView that points to the BindingSource also.
I have added a Save button to the BindingNavigator. I want to enable / disable the Save button depending on whether there are changes in the data to send back to the Access DB. I think this is the code, but I am not sure if I'm really doing what I think I am (i.e. I am concerned I will assume something turns out to be wrong) or if there are better ways.
I am also uncertain what event to use to respond to. I have guessed at CellLeave, but I could be wrong and there might be much better choices. Finally I've been told that it's different if it's a DataTable, but I do not know enough to determine when something is a DataTable?
Private Sub CompClass_DataGridView_CellLeave(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles CompClass_DataGridView.CellEnter Me.BindingNavigatorSaveItem.Enabled = Me.Component_MI_DataSet.HasChanges End Sub
Is it possible to create an application with vb.net to track a users usage of Excel, Word and another application called lets say - Userapp.exe
At work we have been asked to create a diary of our days work and since most of my work is in excel, word and a custom application I have built, I was wondering if it was possible to track the usage of these programs store the data in a datatable and then save it to a access db.
Usage of the program would mean the time that the file is open on the screen, that way the time a program is open but minimised in the taskbar would not be counted.
The data table would have these headings -
1. Program (i.e excel, word etc.) 2. Name of File used 3. Time used in program

I have developed a desktop application that connects to a MS SQL server over a network. One of my clients wants a third party company to be able to use my desktop application but connect to the MS SQL database in my client�s office. Obviously my client could open the ports to the SQL server to make this accessible from the web, but this is a huge security issue and obviously not one I want to even recommend. Is there a way that I can make my desktop application securely communicate over the web to the SQL database?

I have written one application which communicate with one data logger unit (temperature monitoring unit) and download records after some interval. Unit continuously send current temperature which I have to show on screen and after each one hour I have to download log (all records saved inside unit at max 1024) from unit.
Now problem is after downloading log, application get hang or what we called working in background and resume after some time. If I pause debugger in visual studio 2008 it show control at application start (sub main) with message as "application will resume here after completing execution of current function". There is nothing in output window. So how can i trace is there any events got spool or what actually application doing in background.
