sir i started a voluntary blood donors information service. im in need of an application with which i can maintain the database.so can anyone of you make it for me? i will be very thankful to you. the application must contain following fields.
Donor ID
Donor Name
Blood group (must be like a drop down menu with blood groups)
Address
Last blood donated date
phone no
mobile no
date of birth
and in the application there should be a search button with which i can search for a person with a particular blood group.and it must contain add, edit, save, print and delete fields.
please can anyone do this for me....my work will be a bit faster with this one. the application must be simple without installing any extra softwares like dot net,ms access, sql, etc,.
thanks in advance.
regards,
Neetu.

People are here happy to help if you are stuck in somewhere while developing but nobody is free to give you the source code or write a whole application for you. If you need such service you can ask this[^] and this[^] people.
By the way why don't you start the project by yourself and if you are stuck then you can always comeback and ask here.

hi thank you so much for the suggestion.even I'm tired of asking people who are great programmers about my little application.but they dont have any time for this small one. so I was thinking of learning visual basic and prepare a good small application for myself. as I'm a beginner if I get any doubts will surely ask you people.
thank you.

If you concider .NET to be excess software, you're in the wrong forum :P

I hope that doesn't mean you're collecting blood with the competence you're showing here.
I am assuming you have the best of intentions ( that is, that you're trying to create something for a free service, and that this is why you're in over your head ). However, no-one is going to write this for you, and statemetns like:

show that you are really very lost.
1 - you cannot write a VB app without .NET
2 - you need a database for what you're doing, and SQL Server Express is free.
I suggest if you're serious that you buy a book driven to data centric development in .NET and work through it. If you ask specific questions, we'll be more than happy to help you.

thank you so much for the help. I started learning visual basic and it is not very hard as I thought and I can make my application in a few days.
thank you so much.

Duuuuh thats installing extra software. FAIL!

thank you so much you have given me a good answer surely im in need of a pen and paper, as I started learning visual basic and in a few days I'm confident that I can prepare the application of my own..
thanks

How can I change my IP with New IP

Changing your IP is not as easy as 1, 2, 3. You will have to call up your ISP and request a static IP. Most of the time, they dynamically assign you one based on their allocation. Have fun!

I use this and work only static IP. I use DOS command
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If RadioButton1.Checked Then
If Dir("C:\home.txt") <> "" Then
Shell("cmd.exe /c netsh -f c:\work.txt", vbHide)
MsgBox("Успешно приложихте Интернет настройки за дома")
Else
MsgBox("Нямате архивирани настройки за Интернет в къщи, моля първо ги създайте от менюто Архивирай настройки")
End If
End If
If RadioButton2.Checked Then
If Dir("C:\work.txt") <> "" Then
Shell("cmd.exe /c netsh -f c:\home.txt", vbHide)
MsgBox("Успешно приложихте Интернет настройки за работа")
Else
MsgBox("Нямате архивирани настройки за Интернет на работа, моля първо ги създайте от менюто Архивирай настройки")
End If
End If
End Sub
Private Sub ЗаИнтернетУДомаToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ЗаИнтернетУДомаToolStripMenuItem.Click
Shell("cmd.exe /c netsh -c interface dump > c:\home.txt ", vbHide)
MsgBox("Успешно прехвърлихте текущите настройки на интернет у дома")
End Sub

I have a CRC32 function for calculating the CRC32 checksum of a byte array:
Private CRC32Table(255) As Integer
Public Sub New()
Dim dwPolynomial As Integer = &HEDB88320
Dim j, dwCrc As Integer
For i As Integer = 0 To 255
dwCrc = i
For j = 8 To 1 Step -1
If (dwCrc And 1) Then
dwCrc = ((dwCrc And &HFFFFFFFE) \ 2&) And &H7FFFFFFF
dwCrc = dwCrc Xor dwPolynomial
Else
dwCrc = ((dwCrc And &HFFFFFFFE) \ 2&) And &H7FFFFFFF
End If
Next j
CRC32Table(i) = dwCrc
Next
End Sub
Public Function GetCRC32(ByRef bt() As Byte) As Integer
Dim CRC32Result As Integer = -1
Dim iLookup As Integer
For Each b As Byte In bt
iLookup = (CRC32Result And 255) Xor b
CRC32Result = ((CRC32Result And -256) \ 256) And 16777215
CRC32Result = CRC32Result Xor CRC32Table(iLookup)
Next
Return CRC32Result
End Function
The thing is, i want to combine two calculated CRC32's...
Example:
The CRC32 of GetCRC32(New Byte() {1}) is 1526341860
The CRC32 of GetCRC32(New Byte() {2}) is -1007455906
Now, say i do not have access to the bytes anymore, but i do have access to the CRC32 results (1526341860 and -1007455906).
Is it possible to combine these results as if the original calculation were GetCRC32(New Byte() {1, 2}) ?

This is very easy to try with your own test data. You'll find that the two examples you provided will not come out equal. There is no way to combine the results to get the same data.

I developed an application which is based on capturing the screen shots and save as the desired name given by the user.I used sendkeys method to avoid the usage of typing
printscreen key in my keyboard to copy the current screen to my clipboard.In my case I used a picturebox to hold the image and for saving.But if we are pressing the PrintScreen key the it works and without that it also works.The problem occurs during the second time,error occurs that the clipboard is empty or a null value exception is occured.
here is the code which I used.
Public Class main_frm
Dim sav As New SaveFileDialog
Dim i As Integer = 0
Dim abc, nam, path As String
Dim opd As New FolderBrowserDialog
Private Sub main_frm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
disp_pb.SizeMode = PictureBoxSizeMode.StretchImage
abc = "D:\vishnu\Screen\Shots\"
'path = InputBox("Enter the location of file", "Please Respond", i)
End Sub
Private Sub capall_btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles capall_btn.Click
'Try
Me.WindowState = FormWindowState.Maximized
Me.Hide()
SendKeys.Send("({PRTSC})")
disp_pb.Image = Clipboard.GetDataObject.GetData("Bitmap", True)
'Dim path As String
'abc = "D:\vishnu\a.jpg"
'disp_pb.Image.Save("D:\vishnu\a.jpg")
'path = "D:\vishnu\Screen\Shots\"
' abc = InputBox("Enter the name of file", "Please Respond", i)
' path = path + nam + ".jpg"
opd.ShowDialog()
path = opd.SelectedPath
path += "\"
nam = InputBox("Enter the name of file", "Please Respond", i)
path = path + nam + ".jpg"
disp_pb.Image.Save(path)
Me.Show()
Me.WindowState = FormWindowState.Normal
Clipboard.Clear()
'Catch ex As Exception
' MsgBox(ex.ToString)
' End Try
End Sub
Private Sub actcap_btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles actcap_btn.Click
End Sub
End Class

Hi,
you don't need the PRNT SCRN key to capture the screen or the active window; there are better ways to get it done, search the nice CP articles on the subject.
And you definitely don't need a PictureBox to save the content to a file; PictureBoxes exist for
looking at an image, no more, no less.
BTW I did not look at your code since it has no formatting and no monospaced font. Please use
the "code block" button (which inserts PRE tags) when publishing some code.
