Is there a way to write in the code to dynamically update the COM port if the USB/Serial adapter is plugged into a different port?
2nd: How do I have visual basic output the LAT/LONG coords that I have have show up in a form box to a text file every time it updates from the serial GPS?
I downloaded some sample code which includes a database query within the markup code. It makes a query to the database and displays the results of the web form and I would like to divert the output to a text file and I am not sure how to do this?Can this be done from here or would it just be easier to code it in the source and make a new connection to the database?
Sample code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringIP %>"
DeleteCommand="DELETE FROM [ip-to-country] WHERE [ID] = ?" InsertCommand="INSERT INTO [ip-to-country] ([ID], [BeginingIP], [EndingIP], [TwoCountryCode], [ThreeCountryCode], [CountryName]) VALUES (?, ?, ?, ?, ?, ?)"

This is correct as there is only one variable that contains data at the moment (Temperatures(2) ), so the values are 0,0,261,0 for the first line. the increase in temperature was reflected in subsequent readings as it went up to 26.6C and then 26.8C.However I am now stumped... I don't know how I can adapt the code to brake the data up into the 4 variable and place them in to 4 different text boxes.
I'm trying to pass a data packet from the serial data received event.The code can capture the data without any issues.I'm spinning my wheels on getting the data packet out of the thread for further processing.[code]
View 4 RepliesIs there an easy way in Visual Basic to record values to a CSV (comma separated value) file? I would also consider recording values to an xls or xlsx if it is easier. Anyone have any experience with this? Basically, during a loop, I'd like to take the values of 3 different variables and put them on one line of a csv, then make a new line in the csv and repeat with the next segment of the loop.

This question has been most likely been asked a number of times, but really hitting a brick wall regarding this.
The issue is that at the moment, I have to create a database using text files on VB.
So far I have managed to get the code working to add new customer and browse added records, but stuck on how to output/input back and fore to a text file, to store information, and after this input/output the text file to a DB ( Not worried about this at the moment)
Public Class Customer
Dim CmrColl As New Collection 'Create the new collection. Think of this as an array of objects.
Dim itemCount As Integer = 0 'A variable to help us scroll through the objects later.

Using visual studio 2010 on a PC running Windows XP SP3 (32bit) I am trying to read the output from a serial device but only get timed out error?If I open hyper terminal I can see the output, so the hardware and connections are good and the command to send data is working as well?When debugging I have no errors, when the program is run (in debugging mode) I get a timed out error from after the do loop (test=2) All I want to do is have my device output printed to TextBoxLockOut.Text? Note "comstring" grabs my com port the serial device is using - on this computer it is com4, it is a public string

Every line starts with 56000 then the first key, the the second key and the rest of the line. I tried to use SORT, that's included with Windows. It does a pretty nice job, but i need to have my own function in case SORT is not available. The output should write 560001002001 at first.
I have a form that validates a users info, address, phone, etc. I want to have the form submit the data only if all of the fields are valid, but haven't had any luck. Right now the fields are able to validate but the form submits the data to the text file regardless of whether the fields are valid or invalid.
Here is my code

I could use some advice/examples to acheive the following:
I have 1 form, 4 text boxes, (textbox1 ,2, 3, 4)
Textbox1 and Text box 3 and single line text boxes.. Textbox2 is multiline.. (a description field which can be as long or short as the user desires..)
Textbox 4 is a large multi-line textbox that will contain the output of Textbox1,2,3.
I need to find out how to output the contents typed into Textbox1,2 and 3 into Textbox4 while maintaining formatting..
For example, contents of Textbox1 should always be the first text displayed in textbox4, immediately under that should be the contents of Textbox2, and under that, Textbox3
I want to ensure that the text is displayed in that order even if the user enters information into Textbox3 first.. and still displayed in the proper order if Textbox2 has 1 line of text or 20 lines of text.
How could I do this? How can I make the text from one box always be inserted before or After text from another specific textbox when its displayed in the destination Textbox.. (think of Textbox4 like a "preview window" of sorts.. which will later be outputted to an actual txt file.
I'm trying to read a text file with multiple lines and then display it in a textbox. The problem is that my program only reads one line.

I am looking to create a VB 2008 Express programme which converts a data stream from a picoscope muscle sensor into a power output board which controls a mechanism.In simple terms when the Muscle sensor reaches a value of 0.8 V or higher I want the programme to send a text file to the power output control programme, and likewise when the sensor is below 0.2 V I want the power to be zero.
So 0.8 V > = send text file (0O=100%)
0.2 V < = send text file (0O=0%)
so when muscles being senced move the device turns on and off.I think I am successfully getting the data stream from the Picoscope which is plugged in the usb. I am using codes and examples that the programming guide for the device provided.here is a quick snap shot of the code (ps2000 is the driver used for the device)
ps2000_open_unit()
ps2000_set_channel(ps2000_handle, 0, 0, 0, 1)
ps2000_run_streaming(ps2000_handle, 250, 1000, 0)[code].....
how to get the data to be displayed or how to tell the programme to do something with the data.The device also came with an example of how it can record data to an excel sheet if anyone needs the code to gain a better understanding.

View 3 RepliesI work in an engineering design house and programming is not my actual profession. And I am relatively new to VB .net (previous i had worked in vb 6)
I am working on an in house application. I am coding a simple application in vb .net. This applications takes a few inputs from user and calculates a result. Now I want to implement a simple functionality that user should be able to save the input and results just like most of the windows programs can in a new file format. And user should be able to open the save file when desired.
i was just wondering if there was a way that i could compare data stored in a text file such as usernames and passwords with data input into text boxes in visual studio vb2008?
View 6 RepliesIm working on a HSD 32 bit data bus to serial converter via a microcontroller. Now first I want to make a sort of data sniffer to read the data bus (32Bit) .All on the controller side is working and the stream of bytes are coming in via RS232 as 4 bytes in HEX like FD,A5,45,8B . I already converted the bytes in Dec and ASCII to determine what is passed true the bus and how fast and stuff.. Now that is all correct and working very well if the LSB (least significant bit) of the 32 data bus is Data line 0 and the MSB (most significant bit) is Data line 31 but if that is not the case I need to invert the 32Bits (like as I would invert the connector on the bus) . How do I best do this using the 4 bytes I send from the micro controller.
Example:
(MSB) 01001000 01100101 01101100 01110000 (LSB)
HEX= 48 65 6C 70
DEC= 72,101,108,112
ASCII= H E L P
I need to invert it with a button to:
(MSB) 00001110 00110110 10100110 00010010 (LSB)
HEX= 0E 36 A6 12
DEC= 14,54,166,18
ASCII= (SO) 6 : (DC2)
Our application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"
