Slightly off topic, but given that you are (apparently) using Atmel Studio[^] to develop some embedded code application, what exactly is this C# program supposed to be for?
|
|
|
|
|
Yeah, AVR wasn't my decision, but that's another story. The C# GUI is part of an automatic test rig that tests all the functionality of our boards, then programs various aspects of the boards. It tests (currently) 7 boards at a time, but we will soon be expanding it.
Everything but the automatic programming is already working. I left it for last because I thought it was going to be the easy part :P

Sorry for the late response, I haven't been on in a while. The C# side was a computer based GUI to control the automated testing, and display results.

Any of the properties of the Process, or its StartInfo.

Hmmm, I've looked through those settings pretty thoroughly. The problem definitely seem to be in the stream-writer. There are two of us working on this issue, on different machines and neither of can get text into a normal command prompt (but the debugger command prompt).
Can I see the code you wrote to test it? Maybe it will shine some light on our issue.

First of all test StudioCommandPrompt to find out if it is using the standard input, output and error streams correctly.
Here is an example of how it's done using the command processor, cmd.exe, which everyone should have.
At a command prompt enter
cmd < inputcommands.txt > stdout.txt 2>stderr.txt
This will start a new cmd.exe which will take redirected input from the file inputcommands.txt. Standard output will be redirected to the file stdout.txt and standard error to stderr.txt.
A suitable inputcommands.txt is
time /t
date /t
non-existent.exe
exit
Simple stuff: output the date, the time, try to exec an app that isn't there (to cause an error) and then exit.
Here is the contents of the output files
stdout.txt
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.
XXXXXXX>time /t
17:47
XXXXXXX>date /t
14/02/2013
XXXXXXX>non-existent.exe
XXXXXXX>exit
stderr.txt
'non-existent.exe' is not recognized as an internal or external command,
operable program or batch file.
You would have to come up with a suitable set of inputs for StudioCommandPrompt and then run a similar test.
i.e. At a command prompt enter
StudioCommandPrompt < inputcommands.txt > stdout.txt 2>stderr.txt
It probably would be wise to run this test in steps
1) Check if your app will read from redirected input
StudioCommandPrompt < inputcommands.txt
2) If that's ok, test if output can be redirected
StudioCommandCommandPrompt < inputcommands.txt > stdout.txt
3) and separately test if error can be redirected, or possibly if the error stream is used at all.
StudioCommandPrompt < inputcommands.txt 2>stderr.txt
If it all checks out OK come back to me and we'll take it from there.
Alan.

Thanks Alan,
I'm going to start with something posted above, then I'll do this too. It'll take me a bit to make the changes.
|
|

|

ok, I'm an embedded programmer, so that took me a little bit to wrap my head around. I don't think the problem is in the StudioCommandPrompt as I can't get my program to feed input to cmd.exe either. Below is a chunk of test code I put together to just test the connection all together, and it still outputs nothing.
Process Temp = System.Diagnostics.Process.Start("CMD.exe");
Temp.StartInfo.UseShellExecute = false;
Temp.StartInfo.RedirectStandardInput = true;
Temp.StartInfo.RedirectStandardOutput = true;
Temp.StartInfo.RedirectStandardError = true;
Temp.Start();
Temp.StandardInput.WriteLine("Test");
Temp.Close();

I'll list what I've done:
1) Fix error: you had used Process.Start twice
2) Assigned a handler for the OutputDataReceived event. Redirected output is prefixed REDIR to differentiate from normal program output.
3) Activated Exited event and and assigned a handler
4) Error not redirected (makes the test simpler)
5) Start reading redirected standard output after Process.Start()
6) Issue DIR command
7) Issue SET command (to dump the environment variables)
8) Issue EXIT command to close cmd.exe
[EDIT forgot this]
9) Don't close the Process object
using System;
using System.Diagnostics;
namespace AdamB {
class Program {
static void Main(string[] args) {
Console.WriteLine("AdamB Test app");
RedirectionTest();
Console.WriteLine("Press Enter to end when output is complete...");
Console.WriteLine();
Console.ReadLine();
}
private static void RedirectionTest() {
Process Temp = new Process();
Temp.StartInfo.FileName = "cmd.exe";
Temp.StartInfo.UseShellExecute = false;
Temp.StartInfo.RedirectStandardInput = true;
Temp.StartInfo.RedirectStandardOutput = true;
Temp.OutputDataReceived += new DataReceivedEventHandler(Temp_OutputDataReceived);
Temp.EnableRaisingEvents = true;
Temp.Exited += new EventHandler(Temp_Exited);
Temp.Start();
Temp.BeginOutputReadLine();
Console.WriteLine("Sending DIR");
Temp.StandardInput.WriteLine("DIR");
Console.WriteLine("Sending SET");
Temp.StandardInput.WriteLine("SET");
Console.WriteLine("Sending EXIT");
Temp.StandardInput.WriteLine("EXIT");
}
static void Temp_Exited(object sender, EventArgs e) {
Console.WriteLine("MESSAGE: The process has exited");
}
static void Temp_OutputDataReceived(object sender, DataReceivedEventArgs e) {
Console.WriteLine("REDIR {0}", e.Data ?? "Null received -> Output stream has closed");
}
}
}
It's not usual for all commands to be issued before any redirected output appears on the screen and for the Exited event to occur while output is still arriving. Output has finished when the redirected stream is closed and that is signalled by e.Data == null.
Understanding all this redirection stuff is not easy if you are taking your cues from the Microsoft documentation as the examples are poor.
I'll look for more questions tomorrow.
Alan.

Clever.
Obvious when I saw it but certainly can't remember ever considering that option in the many times I have messed with programmatic access to stdin/out.

I gave this a quick try yesterday, but I don't really understand what's going on in his example. I assume it didn't work because I broke it :P

How so? The one file provides input lines. Nothing else.
The output is irrelevant except as a tool to help you.
If you can't get the input lines to work then you need to work on getting the right values or the application is coded in such a way that it will NEVER work with this type of process.

I am doing final year project on the topic object recognition using c#. I am having problem that I didn't have any idea how to use neural network. Since my concept is to recognize the any types of object having different shape and size like human, ball, car. Since I have very few days so anybody can u help me. plz give me some idea with some sample code of object recognition.

You have "very few days" for a final year project? And you picked THIS topic?? What do you mean by "very few days"?? How many are we talking about?? If it's a couple of weeks, you MIGHT be able to pull this off by pulling very long days to work on this project, but since you don't have any neural network experience, I seriously doubt it.

Hi
I need to force users to write in and fill forms using "English". And they cant be able to change language by pressing "Alt+ Shift".
thanks a lot for your helps... 
|
|
|
|
|
Now that's all very nice, but you forgot to ask a question.
Regards,
Manfred

This would be tricky. If you just want to ensure script used is English, it is easy. Just scan every character in the input and make sure all the characters are valid English letters. But user can write another language using the English script. Detecting this would be tough and you need to use some natural language processing libraries.
Best wishes,
Navaneeth

Why does it matter? In "English" you can still type random crap in the form (and if you think that means ascii-only, consider pasting and alt-codes), so you'd still have to deal with it.
|
|
|
|

a simple way is in textbox keypress event! check if user pressed alt or shift , show a messagebox and inform to user that he/she cant use this feature 
and if user changed language before activating textbox, you can check first charecter with textchanged event, if it is a charecter belong to persian (for example) ... with a message box say to user must change his/her language first

Spell check using an english dictionary.

i am trying to download some data from one website i succesfully navigate to the page and invoke click and it is navigate to next page .in the second page there is an iframe which is loading from another url . when am checking document text in my documentcompleted event handler the iframe part is showing youdont have permission to acces the page but in webbrowser control the whole page is showing..
Can anyone have any idea about the problem?
|

If iframe is pointing to a different domain, you will not get access to manipulate it's contents. This is basic security model exposed by browsers. I think you won't be able to workaround this. Check out this[^] MSDN article.

Hey Guys,
I know I can access my ItemTemplated Checkbox this way:
foreach (GridViewRow rowItem in GridView1.Rows)
{
CheckBox ckBxSelect = ((CheckBox)rowItem.FindControl("chkBxSelect"));
if (ckBxSelect.Checked)
{
Response.Write("True");
}
}
Ive built 1 LINQ object joined from 2 Datatables which comes from 2 WebServices. My GridView is bound to my LINQ object. When the user clicks submit, a foreach loop inserts that LINQ object into my database like so:
protected void Button1_Click(object sender, EventArgs e)
{
mySQLDatabaseDataContext dbc = new mySQLDatabaseDataContext("Data Source=JBBBZ7V1\\SQLEXPRESS;Initial Catalog=WLSData;Integrated Security=True");
mySQLTableName newRecord;
foreach (var item in LINQobject)
{
newRecord = new mySQLTableName();
newRecord.CustName = forAppr.custName;
newRecord.Status = "";
newRecord.DateTimeSubmitted = DateTime.Now;
dbc.mySQLTableName.InsertOnSubmit(newRecord);
}
dbc.SubmitChanges();
}
Like I said, my checkbox is in a TemplateField like so:
<asp:GridView ID="GridView1" runat="server"
AutoGenerateColumns="False"
GridLines="Both"
CssClass="mGrid">
<Columns>
<asp:TemplateField HeaderText="Select">
<HeaderTemplate>
<asp:CheckBox ID="chkBxHeader" runat="server" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="chkBxSelect" runat="server"/>
</ItemTemplate>
<HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="50px" />
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="50px" />
</asp:TemplateField>
</Columns></asp:GridView>
When I am inserting from my LINQ object, I would like the "Status" field to update with "True" if checkbox is checked or "False" if checkbox is not checked. Like so:
protected void Button1_Click(object sender, EventArgs e)
{
mySQLDatabaseDataContext dbc = new mySQLDatabaseDataContext("Data Source=JBBBZ7V1\\SQLEXPRESS;Initial Catalog=WLSData;Integrated Security=True");
mySQLTableName newRecord;
foreach (var item in LINQobject)
{
newRecord = new mySQLTableName();
newRecord.CustName = forAppr.custName;
if(ckBxSelect.Checked)
{
newRecord.Status = "True";
}
Else
{
newRecord.Status = "False";
}
newRecord.DateTimeSubmitted = DateTime.Now;
dbc.mySQLTableName.InsertOnSubmit(newRecord);
}
dbc.SubmitChanges();
}
However,
This code will throw an exception because of the object not being set to a reference.
Please help. Is there a better way do update my database?
Im totally lost.
