What part are you stuck on?

As far as reading from the database and reporting its progress. Look into the BackgroundWorker class of the (?)System.Diagnostic namespace. It will create a thread that will do all of the database work, and provide a percentage property so you can control a progress bar.

I googled a lot, but still didn't get exact answer....
In.NET,
When v execute an application,
Wat is compile time error and
Wat is runtime error...
Thanks...
|

Compile time errors are gernally syntax errors which get thrown before excecution and run time errors are those errors which occurs and not handeled while running the application like indexoutofbound,outofmemory etc.

Hi,
I want to create Workflow using C# 2.0. I need to provide UI to allow the user to define a Workflow runtime.Kindly provide me the solution for this.

Sure, but first let's discuss terms. My rate is USD$100/hour with a 40 hour minimum.

The following is the Requirement.
The end User will define the Flow of the Process using UI.Based on that Flow result i need to create one Action.
E.g LEt us consider REcruitment Process
I have to provide UI to create Recruitment Process as a flow diagram.
I need to execute this flow diagram once defined
Based on the Result of flow Execution, i need to provide a grade to the candidate.
I dont know how i can give UI provison to the user to define a Workflow dynamically.
If anyone knows kindly let me know.

I think CodeProject is not made for businiess purpose like this.
It's an platform to save others sinking boat with help them and share knowlege as well.

Yes that true !
but its not true for them who are asking a dumb question by mentioning "please give me source code ", "please Send me solution ASAP", "Its very urgent...please give the full code"..........
Before asking question here , he should read books or search google for proper solution . and he should try it himself , if stuck everybody here to help him. But not in that way he has asked. and for that case I am agree with what Mark suggested  . In my case it is USD$80/Hour

cPtr = (unsigned char *) &Float1 ;
cPtr += 3;
for (k = 0; k< 4; k++)
{
*cPtr = sBuffer [BufPtr++];
cPtr--;
}
How to convert these code to C#? Thanks
|
|

|

It can't be converted, neither sBuffer nor BufPtr are declared.
If I assume sBuffer is a string array and BufPtr is an integer, then you cast it to char. Assuming also that Float1 is a char array;
char[] cPtr = Float1;
cPtr[x] = (char)sBuffer[BufPtr++];

Well, first of all, what are we converting it from? Is this C code? I'll just assume that it is...
As Mark said, without the definitions, one can't make a definitive conversion.
The .NET equivalent of an unsigned char is the Byte data type. If Float1 and sBuffer are byte arrays and BufPtr is an integer, you copy the data like this:
for (int i = 3; i >= 0; i--) {
Float1[i] = sbuffer[BufPtr++]
}
If Float1 is a single precision floating point number (Single), you use the BitConverter class to convert it to an array of bytes:
byte[] data = BitConverter.GetBytes(Float1);
Despite everything, the person most likely to be fooling you next is yourself.

Here are the declaration:
int i, k, BufPtr;
unsigned char *cPtr;
float Float1;
unsigned char sBuffer []
And the purpose of these code is to get the value of Float1.
Thanks
|
|
|
|

If you want the value of Float1, just use the Float1 variable. Example:
Console.WriteLine(Float1);
If you want the memory representation of the variable as a byte array, read my previous post.
Despite everything, the person most likely to be fooling you next is yourself.

.NET 3.0 is an extension to .NET 2.0, not a replacement. Meaning, the version that supports 2.0 also supports 3.0.

Hi.
Does any one know, is there any limit to the buffer size that could be sent at once with the NetworkStream.Write through a socket?.
I'm sending a byte array with a length of 16890, and receiving only a few hundred of them.
networkStream.Write(buffer, 0, buffer.Length);
Please help.
Thanks.

Hi,
I think you can send as much as you like, if not the Write method should/will throw an exception; however when the network (hardware definition and/or protocol) is somehow limited, the protocol stack and/or driver will chop it into several packets.
Example: Ethernet packets are limited to some 1500 bytes (this relates to the collision detect mechanism,
the maximum length of a connection, and the bit rates).
I doubt a receiver will put them together again, so sending 16890 bytes in a single write may result
in some 11 packets being transmitted and received. That is one of the reasons a Read method always
returns the numbers actually read.

To expand on Luc's excellent information, the opposite is also true of the data being spread across multiple packets. If multiple pieces of data are sent that are small, depending on how the OS decides to use it's internal buffers, it may combine one of more and send them as 1 packet.
So, you can see that you have to have some way to sort it out on the receiving end since it may be received completely differently than how it was sent.
One approach is to create your own mechanism, or protocol, for transmitting data. A common technique is to perform 2 transmissions, the first is a small amount of data that contains the size of the data to be sent (can be just 4 bytes representing an Int32). And then the second transmission is the actual data. So, on the client end the first transmission would tell the client to expect N bytes of data. Then the client can read until all N bytes are received.

Lets say I have a database with one table, for the sake of this question, and the table structure is like below:
Customer
========
CustomerID
FirstName
LastName
DateOfBirth
Address
City
Province
Country
PostalCode
I have created a DAL which is a singleton class and has a method called Load() which loads all the customers from the database (Lets not worry about memory issues here). Now what I want to do is allow clients to pass in objects of type T and I will load that object for them. For example, client can pass object X and X only needs CutomerID, FirstName, and LastName and I will load object X with those fields.
The problem is at the design time of DAL I can not anticipate the type clients will pass in. I know I can create a method which takes a generic type and create a constraint on it that it must derive from some class or implement some interface but I can not foretell what interface they should implement or what class they should inherit. A client might pass an object which only requires the ID or 2 fields, or 5 fields and so on.
One solution is clients can pass names of fields in an array and I can return them values in an array but I do not like this option. I want to totally abstract the object loading from the client. Can this be done?
Here is the skeleton:
public class DAL
{
public void Load()
{
// Loads all customers from the database and keeps them in a DataTable
}
public CustomerCollection ToCustomerCollection()
{
// Creates type of Customer which has all fields for customers and adds them to a CustomerCollection
}
public void LoadMe(T unknownType)
{
if (T is SomeAbstractClass || T is SomeInterface) // Not an option
{}
// This method should somehow find the properties of T at runtime and load those properties.
}
}
Note: Both clients and DAL know the fields in the database.
