Hi
Y don't you change this line of code for (int x = 0; x < anArray3; x++)
to for (int x = 0; x < 10; x++) and see.

Hi All,
I have the application developed in MS Dos Basic 3.0.
I want to convert or reverse engineering that application into .Net 2005 C#.
Kindly provide suggestion or ways (any kind of parser is available).

Hi,
We are currently building a Windows Application with Visual Studio, C# and SQL. Exceptions are caught and logged.
Is there a way for us to determine the exact spot in the code where the error occurred, that is the CLASS and the METHOD?
Here is the code we use now:
catch (Exception error)<br />
{<br />
ExceptionHandler.LogError(error, Applications.ID, UserProfile.UserID, Applications.Version);<br />
throw error;<br />
}
The error object gives us Source and StackTrace, but not location.
Thanks for any help,
 Anne

I would probably suggest changing your function to take two more parameters 'this'(which would give you the name of the class sending you error) and a string to have the method name.
ExceptionHandler.LogError(error, Applications.ID, UserProfile.UserID, Applications.Version,this,"this method">");
you can actually use the StackFrame class in "System.Diagnostics;" to get the information you want.
you can change your function to take 2 more parameters
ExceptionHandler.LogError(error, Applications.ID, UserProfile.UserID, Applications.Version, this, new StackFrame().GetMethod().Name);

That appears to give the name of the method that's calling LogError, but the exception may have occured deeper and been bubbled up until finally caught.
This is something that I'm trying to work out as well.

Try
new System.Diagnostics.StackTrace ( error ).GetFrames()[0].GetMethod().Name
the only shortcoming is that it requires debug info to do what I want.
Generally release builds don't include debug info.
I'm still trying to figure the proper settings for a VS project.
When I compile on the command line (with CSC) the switch is /debug+.

I was at a training session yesterday and noticed the developers has placed a small red triangle in the top left corner of a text box to indicate the field was a mandatory field. I thought this would be nice to do in my apps.
Does anyone know where I could learn procedure on how to make a custom control like this.
Regards
Jeff

You may read about custom controls at the MSDN.

Hi guys,
How can I get the resources from a dll, the dll contains a resource(myresource.resx) file.
Can you guys please demonstrate some examples.
Thanks

I tend to write a dll that has methods that know how to return objects from it's resources.

if (GV_OrderDetails.CurrentCell.ColumnIndex == 6)
{
string BarCodeText = GV_OrderDetails.CurrentCell.Value.ToString();
if (BarCodeText.Length > 4)
{
DV_Pro.RowFilter = "Pro_ID='" + BarCodeText.Substring(0, 4) + "'";

Hi Guys,
I've been looking around for a while now, i've seen lots of classes in the .net framework that use sections of xml in the app / web.config to setup the class. I'm sure it's possible to create my own, and I'm wondering if someone can point me in the right direction for some resources on the subject.
Cheers

i am working on a project to communicate with clinets using tcp/ip protocol.
I have a server system where this program is being done. I have clinets which are connnected to my ip. These clients are capable of accepting commands from the server and gove reply for that. For eg:- if i give %Name to clinet it will send back the system ip address.
private void button1_Click(object sender, EventArgs e)
{
Listener = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any,5005);
Listener.Bind(ipLocal);
Listener.BeginAccept(new AsyncCallback(OnClientConnect), null);
}
private void OnClientConnect(IAsyncResult asyn)
{
Client = Listener.EndAccept(asyn);
WaitForData();
}
private void WaitForData()
{
Client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(OnDataReceived), null);
}
private void OnDataReceived(IAsyncResult asyn)
{
Byte[] sendBytes = Encoding.UTF8.GetBytes("%Name");
string szData;
int iRx = 0 ;
iRx = Client.EndReceive(asyn);
char[] chars = new char[iRx + 1];
System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder();
int charLen = d.GetChars(buffer, 0, iRx, chars, 0);
szData = new string(chars);
MessageBox.Show(szData.ToString());
Client.Send(sendBytes);
WaitForData();
}
The sending of data is working fine here. but when i revceive data they are all junk values even after converting to string. Junk vlaues means some single characters only
Please let me know if tehre is someone extertise in this feild as i am new to this
Thanks in advance

I've used:
string receivedText = System.Text.Encoding.ASCII.GetString(buffer, 0, buffer.Count));
Of course this assumes that "buffer" in your case is a byte array.
Also, please be sure to check what the client is supposed to be sending. Is it an array of values that need interpreting? Or is it a human readable string?

I want to take very fast screenshots of my full screen with a timer. I hope this can be done with DirectX.
On this page[^] is an example of doing this in C++. But... the rest of my project is in C#, so I hope it also can be done in C#. I need the screenshot as a Bitmap variabele, it won't be saved as a file.
Hopefully, someone got a full sourcecode example, because I don't know much of DirectX.

A generic collection i.e. cCurves is populated with data.
The collection has several fields.
I am interested in two of the fields i.e. Name and Name2
As a test, the following return data from the collection.
cCurves[0].Name1
cCurves[0].Name2
cCurves[1].Name
cCurves[1].Name2
cCurves[2].Name
cCurves[2].Name2
...
How can I use a loop to populate a simple array with the
data (Name, Name1 fields for each row) in the above collection please?
Thanks
|
|
|
|
|
for(int i=0; i<numElements; i++)
{
cCurves[i].Name1 = whatever;
cCurves[i].Name2 = whateverelse;
}
