hi
I want to make a program. It has an output exe file. Is it possible
writing with c#.net?
why not!?
|

If you're asking whether or not you can run your program as an executable, then you can. Right click on your project and select Properties. Choose the Application tab, and select the Output type to be Windows Application or Console Application depending on which type you intend to deploy.
If you're asking whether or not you can create an executable from your program, then you can do this as well. You need to read up on the CodeDOM[^] classes.

why not ??
if you set application type to ConsoleApplication / WindowsApplication, then the output is EXE.

I'm trying to make a group settings classes that read XML files and set the appropriate fields in those classes. Here are the classes I have:
SettingsBase
System1Settings : SettingsBase
System2Settings : SettingsBase
...
I also have some sub classes that grouped common settings together for easier coding.
class System1Macros
{
string macro1;
string macro2;
...
}
class System1Registers
{
string register1;
string register2;
...
}
Inside each system class, I have some fields that inherit from those classes. For example, inside System1Settings:
System1Macros macros;
System1Registers registers;
My settings.xml files have the format:
<?xml version="1.0" encoding="utf-8" ?>
<System1Settings>
<Setting name="SomeSetting1">Major1</Setting>
<Setting name="SomeSetting2">Major2</Setting>
<Setting name="SomeSetting3">Major3</Setting>
...
<Macros>
<Setting name="Macro1">1</Setting>
<Setting name="Macro2">10</Setting>
...
</Macros>
<Registers>
<Setting name="Register1">1</Setting>
<Setting name="Register2">2</Setting>
...
</Registers>
</System1Settings>
What I want to do is read in the System1Settings.xml file and set all of fields in System1Settings (the values in the first level of the xml file) and the fields in the specialized classes to the other levels of the xml file. So:
System1Settings.setting1 = SomeSetting1
System1Settings.setting2 = SomeSetting2
...
System1Settings.macros.macro1 = Macro1
System1Settings.macros.macro2 = Macro2
...
System1Settings.registers.register1 = Register1
System1Settings.registers.register2 = Register2
...
Right now I'm trying to use reflection in the SettingsBase (thinking I could write this routine once for all child classes and not have to rewrite each time I make a new settings class), but I'm not sure how to drill down through the fields in the SystemSettings classes to know which fields in the child classes are subclasses that need to be set. I thought there was a way to serialize/deserialize the XML, but I don't know that I can use the class structure I have.
Any insights, critiques, or nudge/shove/push/kick in the right direction would be appreciated.
Thank you,
Brad

This doesn't seem like a good use of Reflection and I hope you don't usually resort to Reflection so readily.
Why not pass the section of XML to a method of the class so it can set its own fields?
Or, rather than have the macros and registers as fields of the class, make a more dynamic structure that you populate from the XML?

Hi,
I have creating shared add-in in C# and then am then using Shim on top of it.
Shared add-in has some user defined functins.once you type the UDFs in Excel, it will log in to server using username and password,creates sessions and get the data.
I am planning to move VSTO. Is it possible to introduce VSTO instead of Shim on top of shared add-in?
how can I do it? can any one share the thoughts?

Hi
I am using this code to upload a file to my server but on some computers like 1% of users it doesn't upload the file to the server. After trying to connect on that PC which has the problem, with Filezilla to my server I see that it fails to make the connection because it can't pass the SSL/TLS authentication part.
public static void Upload(string strLocalFileName,string strRemoteFileName, string strUsername, string strPassword)
{
WebRequest wreq = WebRequest.Create(HTTPloc.fileserverurl + strRemoteFileName);
FtpWebRequest ftp = (FtpWebRequest)wreq;
ServicePointManager.ServerCertificateValidationCallback = RemoteCertificateValidationCallback;
ftp.Credentials = new NetworkCredential(strUsername, strPassword);
ftp.Method = WebRequestMethods.Ftp.UploadFile;
ftp.UsePassive = true;
ftp.UseBinary = true;
ftp.KeepAlive = false;
ftp.EnableSsl = true;
FileStream stream = File.OpenRead(strLocalFileName);
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
stream.Close();
Stream reqStream = ftp.GetRequestStream();
reqStream.Write(buffer, 0, buffer.Length);
reqStream.Close();
}
The exception it throws is something like "remote computer didn't answer in the time provided" actually it defines timeout.
User tried OS reinstall but still the same problem. It has to be a problem with the things he does after installation. Any ideas? What causes a problem on SSL TLS authentication?
Thanks.

Good morning.
I set several global variables to be used throughout the form code and when I need to reference the strContainer in the WorkerImport_ProgressChanged event, the value is Null for some reason. It is fine in the Submit event and passed successfully to the WorkerImport_DoWork event. Any idea why the strContainer is Null? My understanding is,with Win form apps the WorkerImport_ProgressChanged event operates on the main (GUI) thread. The code is as follows:

This may or may not be the cause of your problem - there's way too much code there to plough through to be sure...
In your DoWork handler your creating a local variable strContainer and not using the global one
string strContainer = (string)ar[0]; If you meant to use the global one just drop the string at the start
strContainer = (string)ar[0];

Hi Dave.
That's exactly what happened. When I removed the 'string', it displayed correctly. Very strange.
Sorry for the huge posting everyone.
Have a great day,
WHEELS

Cool glad you've got it sorted.
Don't forget to aquire a lock on it as you're in a different thread in the DoWork handler, if it were accessed/modified from two threads at once you would have problems!

Hi,
Have you tried "Find All References" on the strContainer field. I haven't managed to read all of your code snippet(!) but I think you will find it is unassigned.
The btnSubmit_Click method declares a local variable strContainer, probably not what you meant to do.
Alan.

When trying to find the solution to a problem such as this I often set up a quickie test project with all the irrelevant stuff removed such as...
using System.ComponentModel;
using System.Windows.Forms;
namespace TestBGW
{
public partial class Form1 : Form
{
private BackgroundWorker backgroundWorker;
private string testString;
public Form1()
{
InitializeComponent();
backgroundWorker = new BackgroundWorker();
backgroundWorker.WorkerReportsProgress = true;
backgroundWorker.DoWork += new DoWorkEventHandler(backgroundWorker_DoWork);
backgroundWorker.ProgressChanged += new ProgressChangedEventHandler(backgroundWorker_ProgressChanged);
testString = "A";
backgroundWorker.RunWorkerAsync(testString);
}
void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
string passedThrough = (string)e.Argument;
passedThrough = "B";
backgroundWorker.ReportProgress(0, passedThrough);
}
void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
MessageBox.Show(string.Format("{0} - {1}", testString, e.UserState));
}
}
}By the way, if you are accessing values that are not local to the DoWork handler inside it, you should aquire a lock on them first

Although I have all datatable columns set to accept DBNull, my application throws this exception:
[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
public System.DateTime ArrangementDate {
get {
try {
return ((global::System.DateTime)(this[this.tablePaymentArrangements.ArrangementDateColumn]));
}
catch (global::System.InvalidCastException e) {
throw new global::System.Data.StrongTypingException("The value for column \'ArrangementDate\' in table \'PaymentArrangements\' is DBNull.", e);
}
}
set {
this[this.tablePaymentArrangements.ArrangementDateColumn] = value;
}
}
I'm stumped (right now). Any pointers would be much appreciated please.

Hi,
I think DBNull is not compatible with DateTime. You should check if it is DBNull.Value and then send null back. 
greetz
|
|
|
|
|
If that is a strongly typed dataset, you'll find it has an bool IsArrangementDateNull() method. You should use this to check before trying to read the value.
The reason for this is there is no way to cast DBNull.value to a DateTime.
|
|
|
|
|
DateTime is not nullable.

Hi all,
I have a bunch of H264 files with corrupt video profiles (showing a level of 20!) which means they dont work in Windows 7 or on my Xbox 360
I've fixed a few files by opening them up in a hex editor and searching for
61 76 63 43 01 4D 00 C8 FF E1 00 13 67 4D 00 C8
(note the 4D 00 C8 is the profile and level [C8 being the corrupt level])
and I replace this string with
61 76 63 43 01 4D 00 20 FF E1 00 13 67 4D 00 20
[changing the occurrence of C8 to 20 to make the level 3.2]
I have about 300 more mp4 files to do and I dont want to do them by hand, so is there an easy way I can read this in to c# and make the find and replace, then output the file again?
I know I can use things like streamreaders/writers and binary readers/writers, but if someone could offer some simple code on how to do it then it saves me asking bit by bit questions on how to do it 
Thanks

Just sample...
const string SOURCE = @"D:\myFile.bin";
const string TARGET = @"D:\myNewFile.bin";
const string TOSEARCH = "4D-00-C8";
const string REPLACEWITH = "4D-00-20";
byte[] byteArray = File.ReadAllBytes(SOURCE);
string byteString = BitConverter.ToString(byteArray);
if (byteString.Contains(TOSEARCH))
{
string newByteString = byteString.Replace(TOSEARCH, REPLACEWITH);
string[] newByteStringSplitted = newByteString.Split('-');
byte[] newByteArray = new byte[newByteStringSplitted.Length];
for (int i = 0; i < newByteArray.Length; i++ )
{
newByteArray[i] = byte.Parse(newByteStringSplitted[i], NumberStyles.HexNumber);
}
File.WriteAllBytes(TARGET, newByteArray);
}
