Jan 8, 2010Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
View 1 RepliesPassword Loop Textbox - Code Works To Read The Entry Data And To Recognise The Correct Data, And The Incorrect

That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
Read A Data From Textbox Which Is Binded To Datasource
Apr 30, 2009EMP_IDTextBox is from datasource on a form, and I tried to show messagebox to see what the value is
Whenn I try case 2, the messagebox shows me correct value, but not for case 1. It shows me no value even though there is a value.
How do I do it and what is the diffrence between case 1 and case 2?
I tried with a textbox which is not binded to datasource on case 1, then that shows me the value.

Read Raw Data From Excel And Display Value In Textbox?
May 19, 2012I been google search for a while (a month at least). My problem before is how to read raw data from access. however, i find out that access not suitable for my project. I more interested in using Excel, because for later analysis i would came out with graph using excel rather than using access. Since, i been develop a GUI Program for Battery Cyclic Test. The part for Cyclic Test and DAQ Interfacing is done already.
My weakness is not been able to understand/know how to read raw data for particular column, and display it into textbox. In many out there forums or discussion, they explain about this kind of database by using class in VB. But, i would like to implement excel data manipulation in VB-Window Form Application.[code]...

View 5 RepliesHSD 32 Bit Data Bus To Serial Converter Via A Microcontroller - Data Sniffer To Read The Data Bus (32Bit)
Sep 3, 2008Im 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)

Search And Read Textbox?
Nov 12, 2009I am working on a new application that retrieves webpage source info and displays data based on that data. Currently i have it read it from a textbox. What i want the application to do is read this textbox or textfile and seach for <name= and then read the rest of the line that its on. The source of the specific page i'm talking about will sorta look like:
<name=ASDF, Rank=2, Gender=0><blahblah234981723948> <name=A, Rank=3, Gender=1> <name=F, Rank=6, Gender=0>
and after each thing that contains <name= and all the way to the next > it saves the data to a string then adds to listbox
Since this might be confusing to you heres my pseudo
dim Users as integer 'counter
for each line in textbox1.text that .contains <name=
users=users=+1
listbox1.items.add(whatever is after name= and before , in source)
next
and then after that i want to retrieve the gender and rank and ext but you get the point..

View 3 RepliesRead A Decimal Value Via Maskedtextbox (or Textbox)?
Jan 22, 2011In COBOL, I read a value (a currency amount with 2 decimal places, for example) via a picture clause (and a screen section, of course), like:
WORKING-STORAGE SECTION.
01
VALUE-TO-READ PIC ZZZ,ZZ9.99.
...
[Code]....
The tricky part here is, whenever the decimal sign key is pressed, the input procedure understands that the following number is to be displayed to the right of the decimal point (not left).
Now, I'm trying to do this in VB. Unfortunately, my all attempts failed with MaskedTextBox.
Do I have to hardcode this procedure in my program, or is there an easier way to get around this?
