IMO, I have to tell you that there are certainly memory issues when dealing with bitmaps especially of larger size. For project such as GPS, just have larger memory and couple of parallel programming techniques with memory cleau-ups

Hi to whomever may be reading this, my name is Njabulo Mpungose I am a first year IT student at the Durban University of technology in Durban South Africa.My current programming subjects are JavaScript,Java and c#, I am trying to teach myself some other languages as well.I am looking for somebody who has the time and patience to help me along.I think I have grasped the basics but I require someone to help me sort out the murky areas of computer programming. I would highly appreciate it if someone took a chance on me.
My personal email address is: 21124627@dut.ac.za

First, don't include an email. This is a public forum and any responses should be posted here. Also, if anyone would like to respond privately to you they can use the functionality here to do so.
You may want to contact any of the CP Mentors[^] to ask this.
And of course, post any questions you have here. Just make sore to read the posting guidelines, http://www.codeproject.com/Messages/1278604/How-to-get-an-answer-to-your-question.aspx[^]

1) Never post your email address in any forum, unless you really like spam! If anyone replies to you, you will receive an email to let you know.
2) Nearly everybody here works for a living, and doesn't have the time available to do one-to-one mentoring. Besides, isn't that what you are paying your course fees for? A Tutor?
3) Don't try to learn everything at once: if they are teaching you JavaScript,Java and C#, then stick to just them - there is a heck of a lot to learn in the last one alone! Learning in breadth can only be effective when you have reached a sufficient depth of knowledge and experience.
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

I want to connect biometric device in my web base application please help me
|
|

That's far too broad a question. Presumably the device has an API associated with it - you should contemplate using this API, reading the documentation beforehand. Also, are you intending for the device to be situated on the client side? If so, you're probably not going to be able to do what you think you want to do without deploying your functionality as an ActiveX control, and that opens up a whole can of worms.

Judging from the votes, your question is not clear. Could you please explain more what it is you are trying to do?
This is too general a question to be answered; you need to give specifics

having problem to translate from WinForm to Windows-CE C# program - FTP transfer
i have this code for transfer from Local computer to FTP server
its work excellent on WinForm, i must have this on Windows-CE and it dosnt work
the code:
string MyFile = @"d:\PC.sdf";
string url = "ftp://127.0.0.1/PC.sdf";
FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(url);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.UsePassive = true;
request.UseBinary = true;
request.KeepAlive = false;
using (Stream reqStream = request.GetRequestStream())
{
int count = 0;
byte[] buffer = new byte[100];
using (FileStream file = new FileStream(MyFile, FileMode.Open))
{
while ((count = file.Read(buffer, 0, 100)) > 0)
{
reqStream.Write(buffer, 0, count);
}
}
}
in WinCE there isnt FtpWebRequest or FtpWebRequest
i think that i need to use OpenNetCF ????
can i get any C# sample code for this ?

Firstly, always use the code block widget when posting code samples - it preserves the formatting and makes it easier to read. (you can edit your question and add it)
Secondly, "it dosnt work" isn't particularly helpful - what does it do that you didn't expect, or not do that you did? Was there an error message?

We had a module that could log to an Oracle (and file if you wished), but my boss now wants to use the MS Enterprise library, where Microsoft of course only provides information on how to log to SQLServer. I searched on the net and found an article about how to log to Oracle, but unfortunately it is outdated (still uses Lib 2.0 and we're on Lib 5.0) Has anyone have any experience with this, because I'm stuck on this a little.
I did find a workaround by modifying the existing dll we had, attach it to the Enterprise Lib and use that one to write to Oracle, but personally I feel it is slow and the format of the log is dreadfull.
Any pointers on this would be very helpful.
thanks.

Hello.
If I have an uint value, that may be differnt lenghts, how would I create a new int from it at a fixed length, or better still select specific digits.
e.g
uint begin = 293844; OR 29388493
uint shorter = 2938;
OR
uint select = 2339 (skip every other digit).
I basically want a new value from a uint that could be different sizes, and ensure the new value is a fixed length in size.
I have a feeling I need to use bit wise operations, but still dont understand them fully.
Thank you in advance for any advice.
Kind Regards,
Stephen

Looks to me like you should be looking at string operations. Convert your number to a string, then play with characters or substrings. Convert back at the end if you need to. Bitwise operations don't match up with decimal digits.

Wow! Never even thought about doing it that way!
Thank you,

You could do this with bitwise math if you also throw in a lot of divisions and multiplies by 10..
But it will be a mess.
Why are you working with decimal digits anyway?
What is the actual problem you're trying to solve, maybe it could be done with hex digits instead?
|
|
|
|

A uint is always the same size (32 bits).
What you're trying to do is string manipulation of a decimal number, quite a strange thing to do but probably best done on the string representation.
|

|

I'm not sure how do you want to get the second sample. In the first case, string manipulation is a way to go. Other, more math (and probably faster) solution is to get a length of begin and then divide it by 10^(length-4). Ot sth like (not tested):
uint shorter=begin;
while(shorter >= 10000) {
shorter /= 10;
}

Thank you everyone. If I explain my requirements maybe it will help.
I am generating a serial number in the following format:
00000-00000-00000-00000
I pass in two values into the serialGenerator class
int ProductID
int ProductVersion
I then combine these into one int value, say for example 12345123
Then I get the hex byte array representing this value, and hash it.
I then take 2 bytes of the hash from predetermined positions.
Then, I need to perform the bitwise so that I take a fixed part of teh new int value, which will always be 5 digits (first part of the serial number)
Generating the rest I have figured out.
Hope this clears things 
Regards,
Stephen

You can't get 293844 from two "bytes".
Largest unsigned value from two 8 bit bytes used to create a 16 bit value is 256*256=65536.

I use the following code when closing a form:
protected override void OnClosing(CancelEventArgs e)
{
//Your alternate implementation
FormClosingEventArgs ce = e as FormClosingEventArgs;
if (ce != null)
{
switch (ce.CloseReason)
{
case CloseReason.ApplicationExitCall:
//Handle application exit call
break;
case CloseReason.FormOwnerClosing:
//Handle Form owner close
break;
case CloseReason.MdiFormClosing:
//Handle MDI parent closing
break;
case CloseReason.None:
//Handle unknown reason
break;
case CloseReason.TaskManagerClosing:
//Handle taskmanager close
break;
case CloseReason.UserClosing:
//Handle User close
break;
case CloseReason.WindowsShutDown:
//Handle system shutdown
break;
}
}
base.OnClosing(e);
}
However on one of my forms it just working, it used to work fine
I setup a new form but still no results, I set a breakpoint and it doesn't even hit it.
Can anyone help with this problem.
Any help will be appreciated.
Thanks in advance,
Michael

I find your code confusing for two reasons
1) you override OnClosing instead of the preferred OnFormClosing method. Are you targetting .Net 1.1?
2) you cast the CancelEventArgs to FormClosingEventArgs. Surely this will never work and the resultant value will always be null.
The breakpoint problem might be explained by the cautionary note regarding the Application.Exit method in http://msdn.microsoft.com/en-us/library/system.windows.forms.form.onclosing.aspx[^].
