Clear Text Fields In Visual Basic Web Developer
Apr 7, 2012
I have a web page that has a few text fields, and a reset and submit button. I'm having trouble getting the reset button to work to clear the text fields because the required field validators and regular expression validators are blocking any code in the reset button's click event from occurring. how to get the validators to not activate when the reset button is clicked? One method I tried was to set the enabled property of all the validators to false in the reset button's code block but no luck.

I am C# developer and now I am involved in some large, already in production, project that is written in Visual Basic.NET.I am trying hard not to write in C# and use some automatic conversion tool to Visual Basic.NET. I want to be able to read and write fluently in Visual Basic.NET QUICKLY. I can write and read VB.NET but it is not so easy like writing and reading C#.

I'm a software developer and use visual basic 2005 and access 2007.Well first programmed with Visual Basic 6 but I decided to switch to. Net and indeed it is a big step.
Finally, in vb6 did not need the database linked to software to generate reports because it filled from a listview as the connection to the database do it for DAO ("C: ProSoft Billiard Data.mdb"). Now the question is as I can if I have to file a report so the connection in my software? is a bit urgent as I have to give and software and I need to do the reports.

Dim strFmt As String = "{0,13}{1,13}{2,13}{3,10}{4,13}"

What I have is on my form there are several text boxes. These text boxes are for user input and attached to each text box is a Private Sub txtBox1_KeyPress function. In that function I have some validation code to check that the user is inputing only what I want them to. And if it doesnt it will pop up a message box telling them so, then it is supposed to clear the text box so the user can try again. But no matter what I try, the text box does not clear it still keeps the last character typed (the invalid one).
Here is the code for one of the text boxes.
Private Sub txtLanIp_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtLanIp.KeyPress
Dim strEmpty As String = ""
If Char.IsDigit(e.KeyChar) = True Or Char.IsPunctuation(e.KeyChar) = True Or Char.IsControl(e.KeyChar) = True Then
'do nothing
[code]....
The commented methods at the bottom are some of the other things ive tried to make this work. The txtLanIp.text.clear() is what ive tried from the beginning. I have also tried setting the text to "", I even created an empty string and set the .Text value to it but no matter what it wont remove that character. I have also tried various trim(), len(), Select() functions, most either give me an 'index out of range error', a 'length cannot be less than zero' error or a general ExceptionOutOfBounds error. I am just tearing my hair out as to why the simple way doesnt work, there is no logical reason why and it gives no error it just doesn't clear the box.
I have also tried moving the validation to a _LostFocus but e.KeyChar isnt a valid method or property for that declaration, which doesn't surprise me but I wanted to try everything.I dont see how it would matter in this case but I am running Windows XP Pro SP3, though I also see the same behavior in Windows 7 64 bit ultimate sp1 and windows 7 64 bit pro.

I am writing a visual basic.net application to pass remote shell command through command prompt. I need to get the text response after the rsh command is executed. My program codes can only get the output 'C:>' text (see below command prompt window display). Is there any solution for me to get the 'Permission denied' text as well?
Program codes:
RshProcess.StartInfo.FileName = Environment.SystemDirectory & "cmd.exe"
RshProcess.StartInfo.Arguments = "rsh..."

I get an error that says Setup Stopped working when installing Microsoft Visual Web Developer 2008 Express Edition with SP1 . Everything else installed fine. I am using the Offline ISO.

Google search does not help. What is really funny about this is that from my search I see there are multiple solutions for this problem that have worked for different people, none of which apply to my situation.Why do I get the feeling that God does not want me to learn VB programming? (Grin)

I am working on a program for the Windows Mobile 6.0 system and using Visual Basic 08. I would like for the current txt file that I have, that is formatted as follows: "NOR400","277225","ZIMA 4/6 12OZ NR BOTTLES","07199077603",21.65,"cs",7.19,"pk","C4/6PK","12 OZ "
to be imported and each item in the line will be assigned to its own txt box. I have been able to load up the file, in to one txt box, but am unable to separate the items in to their own box. Should I be using arrays for this?

Ok, so I'm making a program that will read from a text file, convert each line into an array, the. Send each of those lines 1 per tick. This is in 2010 Visual Basic. Closest I've gotten is sending all at once, I worked on it over night and am slowly destroying it. Ideally, I want Button 1 click to populate the array from the file at LocationTB then start the timer. The timer should send a line at a time on the GapTB interval.
Public Class Form1
Public TextLine As String
Public MyFileName As String

I am reading a temperature value from a transceiver into the serial port and I want this value to change the value of a label in my Visual Basic Form. This value changes every few seconds. I am using the code below:
Me.dataReceived.Text &= [text]
where dataReceived is the label I am using and [text] is the data I am reading from the serial port. This results in the data being displayed but instead of overwriting the label, it writes the value after each other. (The data is appended). I tried to remove the & before the = but this did not work as nothing showed up.?The code I am using is the following:
'To receive data into the text field
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived

Basically, the question is: Where (and in which format) should I store textual developer documentation associated with my Visual Studio projects?
To elaborate: XML comments are great, but they don't cover all use cases. Sometimes, you'd like to describe the class architecture of the project at a high level, add usage notes to your library or just leave any other kind of message to future generations of developers working on this project.
I'd like to add these documents directly as files into the Visual Studio project, to ensure (a) that they are available to the developer without further searching and (b) they are version controlled (using the same svn/git/whatever repository as the source code).
Currently, I add a folder _Documentation to the project and use text files, but I'm not sure if this is the best solution. Visual Studio does not have an option for automatically word-wrapping text1, and manually fixing line breaks after each change is annoying. On the other hand, Word documents don't work well with version control, and TeX is too much of a hassle to set up and teach on each developer PC.
Is there a well-established best practice for this?
1 I know that there's Edit/Advanced/Word-Wrap, but this only affects the display, not the file itself.
