Not sure how to make it simpler. If you get a divide by zero exception, that property must, inside .NET, do a divide by a value that's getting set to zero. Use reflektor or similar to find out what the source code for that property is, and instead of accessing that property, write your own that checks the values it uses, but first makes sure the value being divided by is not zero, and if it is, find a way to deal with that.

I am making codoing changes to my Visual Basic.Net project but when I execute the code using the debugger, I see the old code. I added a new button to a form but when I execute the code, the button is not there. It seems like the code is executing from a different library.
Any suggestions?

Change your settings to run the debug version.

Something like:
Public Function GetGridData(ByVal value as Object) As Object
For Each dr as DAtaGridViewRow In dgv.Rows
If dr(0).Cells.Value = value Then
Return dr(1).Cells.Value
End If
Next
End Function

Thanks Andy. But one thing, If My number of rows are 5000, then will this search be fast?
Because I have to run this search 2-3 times in my complete project.

hi,
i have a textbox and i want to copy the contents of the textbox into a .txt file.
my current code works however when i open the .txt file it comes up saying
"System.Windows.Forms.TextBox, Text:" then what i actually want in the .txt file
is there any way where i can stop this from happening and just displaying what i want in the text box in the .txt file?

Can you see anything wrong here? You aren't writing the text to file.
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

at the beggining i have

Doesn't the TextBox1 object you have expose a Text property??
Seriously...pick up a beginners book on VB.NET. You're showing us you don't understand the basics of the language, the basic .NET object model, and a bunch of other stuff that makes it very difficult for you to understand the answers you're getting. This is just another example of it.

hello,
my last question was basically on the lines of how do i use the command prompt in vb.net to recieve information. I want to try and get the serial number of command prompt (wmic bios get serialnumber - in command prompt) this will then bring up a serial number
someone answered my question with a line of code that proably does work however ia m having trouble incorprating it to do what i want it to do. I want to copy the serial number fro the command prompt into a text box?
here is my code
Imports System.Management
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SerialNumber As System.Management.ManagementClass
Dim Win32_BIOS As System.Management.ManagementObjectSearcher
Select Case SerialNumber FROM Win32_BIOS ' surely FROM should be in blue???
End Select
textbox1.text = SerialNumber 'copys serial number from the Win32_bios into the txtdocument
End Sub
End Class
i am a bit of a beginner/intermediate but it would really mean allot if i could get this working
many thanks

Oh no. It takes a bit more code. I only have a C# example showing all non-null entries in Win32_BIOS:
ManagementObjectSearcher searcher=
new ManagementObjectSearcher("SELECT * FROM Win32_BIOS");
ManagementObjectCollection results=searcher.Get();
foreach (ManagementObject result in results) {
PropertyDataCollection pdc=result.Properties;
foreach (PropertyData pd in pdc) {
string name=pd.Name;
object obj=pd.Value;
if (obj!=null) output(name+" = \""+obj.ToString()+"\"");
}
}

Many thanks

thanks again for the super quick reply
umm this is how far i have got and then i get stuck
Imports System.management
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SerialNumber As New Management.ManagementObjectSearcher("serialnumber Win32_BIOS")
Dim pd As String
For Each management.ManagementObject result in result
PropertyDataCollection(pdc = results.properties)
for each propertyData pd in pdc)
if (obj!null) output(name+" =\"+obj.tostring()+"/") then
textbox1.text = SerialNumber
End If
Next
End Sub
End Class
this don't work it doesn't like the if statement and the for statement either

all it takes is for you to understand how it works (see documentation and my example), then write code accordingly in the language of your choice.
And why did you modify the SQL-like statement in the ManagementObjectSearcher?
I will no longer hold your hand, please learn to help yourself.

that is the problem i don't understand c code. I am just about alright with vb.net code however i was trying to use you r code which u kindly wrote but i really haven't got a clue to writting it in vb.net. The only reason that i had to change the managemt SQL into "serialnumber Win32_BIOS" was because it didn't like "serialnumber" from "win32_BIOS"
I thank you for your work however i don't know c so would you be able to help me transfer it to vb.net?
many thanks

That's because it's not supposed to be in blue at all. That SELECT statement was supposed to be specified in the parameters of the objectsearcher class, not as a stand-alone statement. When I told you to look at the example in the link that I gave you, I would have thought that is was very obvious where that statement goes. I mean, in the example, there is a statement almost exactly like it.

should be
Dim SerialNumber As New Management.ManagementObjectSearcher("SELECT SerialNumer from Win32_BIOS")
Then you can get rid of the contents of that loop and replace them with some simple code to display result 's SerialNumber property.
