I've been working on this and everything is going really well except one thing.. some colors are coming up different from photoshop vs when deployed in the application.
One color I chose is a redish color..
In photoshop it shows:
R= 253
G= 54
B= 0
But when I display the color in my application it shows as
R= 253
G= 29
B= 0
which is giving different colors? Any idea why? I saved it as a GIF format as you suggestde

I don't know, and I'm not sure it is relevant. I did suggest you use your app to sample the colors, then type those values into your data initialization statements, rather than reading them from the creating app's dialogs.
You could close Photoshop, then restart it to open the same image again, and have another look. Maybe somehow the colors got changed while saving. Did you have to specify some "quality" wishes?

I didn't any quality options. I'm guessing it was just to close and it converted it to the actual RGB red color? Not sure.. I just pick a different color
Just found it odd that it did that. Thanks again!

You're welcome.
And yes, the color drift sounds odd.

I can't be certain of what you are asking, but if you are looking into working with your serial port, here would be a good start

Hi
I am having trouble streaming jpeg's from a server to a client using TCP. A lot of the images I recieve are corrupt and some of them are superimposed on top of each other. I have used blocking, non blocking TCP and havnt been able to fix it.
I believe that to much time is being taken up processing each frame before recieving the next frame. Therefore the TCP buffer is being overwritten with the next TCP packet.
Is this what is happening or is it somthing else? And does anyone know how to fix this problem?
Thanx

This is the third day in a row you present the same problem without actually offering any tangible information. You did not tell what classes you use, whether you use extra threads or asynchronous operations, you did not show any code, nothing.
I don't think there are many mind readers here, so the only possible answer is: you either have a conceptual bug, or an implementation bug in your code, or a general PC problem, or very bad luck, or something else.

Ok the reason I havnt provided more info is becuase I have used mutliple methods to try and solve the same problem and none have worked. Blocked socket, non blocking socket, tcpclient ect and all have failed. Therefore the problem is not with classes or extra threads.
I have found out that I am having this problem because I am expecting to recieved the whole message in one read rather than multiple reads.
I need to learn how to frame the data. A beginners mistake

The main mistake is not to provide any information on a single attempt; that way nobody can help you out.
Had you shown code, you would most likely have gotten the right answer pretty soon.

Hi everyone,
I'm developing an application that needs a new bluetooth profile, so I have to modify the Bluetooth stack to fit my requeriments. The stack should be something like this http://www.musenka.com/info/doc/MDP(MedicalDevicesProfile).pdf[^]. But I really don't know how to begin. I don't know if there is an open implementation of the BT stack that I can modify... Or if there is a way to use other stacks parts... I'm writing this in C# forum because my app is in C# but I suppose the stack changes and everything will be in C++.
Any help would be appreciate 
Thanks in advance
Kind regards

Hi every1,
I am working with lists and faced with a problem.
this is the method in my first class which has implemented in DAL
namespace Assignmnet2
{
[Serializable]
class Student_Manipulation
{
public void ReadStudentFile(string Fr_Name, string Sr_Name, string St_Id, int Lb_Mark, int Ass1, int Ass2, int
Fnl)
{
FileStream flstream = new FileStream("c:\\student.dat",FileMode.Open,FileAccess.Read);
BinaryFormatter BnFrmt = new BinaryFormatter();
List<ITECH3219Student> list = (List<ITECH3219Student>)BnFrmt.Deserialize(flstream);
foreach (ITECH3219Student ITECH3219Student in list)
{
Fr_Name = ITECH3219Student.Fr_name;
Sr_Name = ITECH3219Student.Sr_Name;
St_Id = ITECH3219Student.St_Id;
Lb_Mark = ITECH3219Student.Lb_Mark;
Ass1 = ITECH3219Student.Ass1;
Ass2 = ITECH3219Student.Ass2;
Fnl = ITECH3219Student.Fnl;
}
}
}
-------------------
In BLL I have this class
namespace Assignmnet2.BLL
{
class Finalization
{
public void read(string Fr_Name, string Sr_Name, string St_Id, int Lb_Mark, int Ass1, int Ass2, int Fnl)
{
Assignmnet2.Student_Manipulation read = new Assignmnet2.Student_Manipulation();
read.ReadStudentFile(Fr_Name, Sr_Name, St_Id, Lb_Mark, Ass1, Ass2, Fnl);
}
}
}
----------------------
Now, in peresentation layer I have this code
private void Form1_Shown(object sender, EventArgs e)
{
Assignmnet2.BLL.Finalization ReadStudent = new Assignmnet2.BLL.Finalization();
LstBox.Items.Add(ReadStudent(ITECH3219Student.Fr_name + " " + ITECH3219Student.Sr_Name + " " +
ITECH3219Student.St_Id));
----------------
Frankly, I don't really know what I supposed to write in this layer in order to show file's information in listbox.
Could you please help me?thanx

Please edit your question to put your code between <pre>... your code here ....</pre> tags.
I for one will not even attempt to read such unformatted code. It hurts my eyes!!

That is still not readable.
Firstly, do it by editing your original question, not by answering this.
Secondly, put the <pre> tag before your code and the </pre> tag after your code. Then format the code, indents etc..

Guys, Could you please help me how Can I sort out my prob.thx

OK. That is much better.
In your ReadStudentFile(string Fr_Name, string Sr_Name, string St_Id, int Lb_Mark, int Ass1, int Ass2, int Fnl), what are the parameters (Fr_Name, Sr_Name etc.) supposed to be for? You are not using them to pass data in and they are not configured to return data and even if they were they would only return the last student in the list.
Unless I have totally misread your code ReadStudentFile would be better as something like:
public List<ITECH3219Student> ReadStudentFile(string Fr_Name, string Sr_Name, string St_Id, int Lb_Mark, int Ass1, int Ass2, int Fnl)
{
FileStream flstream = new FileStream("c:\\student.dat",FileMode.Open,FileAccess.Read);
BinaryFormatter BnFrmt = new BinaryFormatter();
List<ITECH3219Student> list = (List<ITECH3219Student>)BnFrmt.Deserialize(flstream);
return list;
}
Your Assignment2.BLL would also need to be rewritten to return the List<ITECH3219Student>, once again no obvious need for the parameters.
and then in your Form1_Shown something like
private void Form1_Shown(object sender, EventArgs e)
{
Assignmnet2.BLL.Finalization ReadStudent = new Assignmnet2.BLL.Finalization();
List<ITECH3219Student> studentList = ReadStudent.read();
foreach (ITECH3219Student student in studentList)
{
LstBox.Items.Add(student.Fr_name + " " + student.Sr_Name + " " + student.St_Id));
}
}
This should work, although I have to say that the slightly 'artificial' way that you have divided the functionality between the various classes indicates that you have not really understood the assignment.
Good luck!

Ummmm....homework?!?!?! Why did you provide an answer to this that included an implementation? Did you not notice that his namespace is "Assignment2" ?

Hi,
I really appreciate for your reply.I realized my problem in first part, as you said.
still I am confusing regarding this line
Your Assignment2.BLL would also need to be rewritten to return the List, once again no obvious need for the parameters.
Could you please explain a little more. why I don't need parameter?
Thanks in advance.

You don't need the parameters because you aren't using them.
As I said in my previous reply, you are not passing any data in them and they are not configured to return any data.

Hi Every One,
I write this code and as you said I fixed it up(Follow your instruction).
but I got a problem
Error1: Cannot implicitly convert type 'string' to 'System.Collections.Generic.List<Assignmnet2.ITECH3219Student>' C:\Assignmnet2\Frm_View.cs
Error2: 'Assignmnet2.BLL.Finalization.read()': not all code paths return a value C:\Assignmnet2\BLL\Finalization.cs
Error3: Since 'Assignmnet2.Student_Manipulation.ReadStudentFile()' returns void, a return keyword must not be followed by an object expression C:\Assignmnet2\DAL\Student_Manipulation.cs
this is the code which I have modified it.
class studentmanipulation which is in DAL
public void ReadStudentFile()
{
FileStream flstream = new FileStream("c:\\student.dat", FileMode.Open, FileAccess.Read);
BinaryFormatter BnFrmt = new BinaryFormatter();
List<ITECH3219Student> list = (List<ITECH3219Student>)BnFrmt.Deserialize(flstream);
return list;
}
------------------------------------
Class finalization which is in BLL
public string read()
{
Assignmnet2.Student_Manipulation read = new Assignmnet2.Student_Manipulation();
read.ReadStudentFile();
}
----------------------------
and Presentation Layer which is my form
private void Form1_Shown(object sender, EventArgs e)
{
Assignmnet2.BLL.Finalization ReadStudent = new Assignmnet2.BLL.Finalization();
List<ITECH3219Student> studentList = ReadStudent.read();
foreach (ITECH3219Student student in studentList)
{
LstBox.Items.Add(student.Fr_name + " " + student.Sr_Name + " " + student.St_Id);
}
}

I just finished a graphical password system and want to use it on my computer instead of the winlogon. Can anyone offer help
|
|
|
|
|
Windows XP, 2000 and server 2003 use a system called Graphical Identification and Authentication (or GINA). It is possible to replace the default MSGina.dll with a custom dll to customize the login and authentication process.
You can read more about GINA and the Winlogon system on MSDN[^].
Windows Vista, 7 and server 2008 no longer use GINA. Instead Winlogon controls the logon process and allows custom credential providers.
Again, there is lots of information about custom credential providers on MSDN[^].
You might also want to read the wikipedia articles on Winlogon[^] and GINA[^] for some basic background info.
You are asking this in the C# forum, but this kind of windows integration is going to need to be done largely (if not completely) in an unmanaged language. There is an MSDN magazine article on custom credential providers that should get you started[^].
