=) thank you.
i have done the codings for each individual buttons.
Eg for the button 9:
Private Sub btn9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn9.Click
TextBox1.Text = 9
temp = 9
End Sub
However, I can't figure out what should the code of '+' be.
Since when a user clicks on it, he/she will select another number button.
So is it simply this:
TextBox1.Text = Int(TextBox1.Text) + Int(TextBox1.Text)

Here are some pointers:
You need to hold some state somewhere. You also need to hold the fact that the user can type numbers like 98 (the code you showed does not append more digits, it replaces them).
When a use clicks on an operator button (+-/*=) the program needs to store the current display, then it needs to accept a new number. When the user next pressed an operator it performs the function of the operator on the stored value and the current value.
When a user clicks on a digit button it has to append the value on to the other digits received.

You got the response you did because we don't do people's homework here. If you try to do your own homework, then we're happy to help with specifics.

I have some idea for you:
A. For the numeric buttons write scrip like this:
<br />
private sub btn1_click(..)<br />
txtT.text = txtT.text & "1<br />
end sub<br />
<br />
' etc. for all numeric buttons<br />
B. For command buttons ( + - * / etc. ) write this script:
<br />
private sub plus_click(..)<br />
Tmp1 = cint(txtT.text)<br />
act="plus"<br />
txtT.text=""<br />
end sub<br />
C. For = button write:
<br />
private sub ans_click(..)<br />
Tmp2 = cint(txtT.text)<br />
select case act<br />
case "plus" : txtT.text = tmp1+tmp2<br />
case "minus" : txtT.text = tmp1-tmp2<br />
....<br />
end select<br />
end sub<br />
This code handle only one action per two numbers.
If you wans to handle lot of actions, like windows calculator, you need to add a boolean trigger that will be True if one action had been chosen and when the user select another action it will do the action selected before, then put the result in Tmp1 and then reset the trigger to False. This process will continue until the user click the = button.
I'll don't give the answer for this so quickly ..  I give you time to think about it.

Well, based on this question
aurora56 wrote: our lecturers just threw us this homework without giving any help...
I suspect this is not true.
Giving you code is not helping you. The answer to all of this is just a google away. If you can't do the most basic research, you need to quit your course.

Has Christian Graus said, if you can't do the basic research source codes may not help you.
The idea of programming is to think about the algorithm you want to write and then think how to make it work in the easiest and quickly way you can. The speed is not only for saving project develop time yet also to increase the computer efficient. Processing resources is an expensive resource.
There are few tips for you, when you want to write a computer program:
1. Define your needs and targets and the system the program will run over it (ex. windows XP, CE, Mobile Phone, etc.)
2. Multiply the targets into missions and sub-missions that will be easy to implement.
3. After you define the targets try to write algorithm (not in VB but in piece of paper) this will help you to rearrange your minds and way of work. you may also draw your tasks to think about visually.
4. The next step is to write it in VB and debugging.
Good Luck !
Web site with source codes: http://www.planetsourcecode.com/
You may use such web sites (you may find a lot of them in one Google simple search) only for helping you with scripts you can't think about your own algorithm. those sites are not good for learning from the beginning.
Hope I helped you

Hey Guys
Using Vb.net 2005,
I want to read each part in this string in an array (splitting the string)
-----------
A1/EXT "BK82 LB73 21233" 105 061018 1804
-----------
That Code that i used is as follow:
Dim s As String, h As String
Dim delim(1) As Char
delim(0) = "/"
delim(1) = " "
Dim f() As String
s = A1/EXT ""BK82 LB73 21233"" 105 061018 1804
f = s.Split(delim)
-----------
The problem that I m facing is as follow :
even what is inside the double quotes is devided into parts
what should i add to my code (or any other solution),
in order to keep what is inside the "" with splitting
Regards,
Ramy

You need to use a regex to follow more complex rules such as 'split on spaces not within quotes'.

Try this:
<br />
dim S2Split As string = "A1/EXT "BK82 LB73 21233" 105 061018 1804"<br />
dim delim(1) as char<br />
delim(0)="/"<br />
delim(1)=" "<br />
dim f(0) as string<br />
dim I as integer<br />
dim J as short<br />
dim Tmp as string=""<br />
dim Ad as boolean<br />
dim fPos as integer =0<br />
<br />
for i=0 to s2split.length-1<br />
Ad=true<br />
for j=0 to 1<br />
if s2split(i)=delim(j) then ad=false<br />
end for<br />
if ad=true then<br />
tmp=tmp & s2split(i)<br />
else<br />
f(fpos)=tmp<br />
tmp=""<br />
fpos += 1 'New feature in VB.NET 2005 ;)<br />
redim preserve f(fpos) 'preserve means that increasing f and saving the ' 'previous data<br />
end if<br />
end for<br />

Dear Reuven.
thx for your help
Just a Question?
Have you tried out this code?
coz when i was trying out ,i faced a problem with the foor loop-(Next)
that's why i couldnt compile this code
Regards
Ramy

My mistake, I replaced Next I and Next J with end for...
for i=0 to s2split.length-1
Ad=true
for j=0 to 1
if s2split(i)=delim(j) then ad=false
end for 'replace with Next J
if ad=true then
tmp=tmp & s2split(i)
else
f(fpos)=tmp
tmp=""
fpos += 1 'New feature in VB.NET 2005
redim preserve f(fpos) 'preserve means that increasing f and saving the ' 'previous data
end if
end for 'replace with Next I

Hi
Following are the code to execute the report:
Public Sub LoadReport(ByVal rptPath As String, ByVal dTbl As DataTable)
Dim oRpt As New ReportDocument
oRpt.Load(rptPath)
oRpt.SetDataSource(dTbl)
crptviewer.ReportSource = oRpt
crptviewer.RefreshReport()
End Sub
Dim ofrmRptViewer As New frmReportViewer
ofrmRptViewer.MdiParent = MDIMain
ofrmRptViewer.LoadReport("D:\DMS Source Code\DMS\Reports\rptDistributors.rpt", ds.Tables(0))
ofrmRptViewer.Show()
I m trying to generate report but the following error is occuring:
DLL 'D:\DMS Source Code\DMS\bin\Debug\CrystalDecisions.CrystalReports.Engine.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.
