Is the browser running javascript ? Did you install XP SP2 ? That could be turning off jscript support in the browser. Although, the rest of ASP.NET relies of jscript - are you sure your scripts are being inserted into the pages still ? How do you insert them ?

I have a windows form with an com component.This application works fine on local hard drive but when i acces my application from the network it gives system.security.securityexception:Request failed.What should i do

I guess that you are trying to load the application after mapping the network drive (directly from server instead of installing). is it true ? if yes then remember that application will load in your system and in your system com component does not exist. So install it on your machine.

make your question more clear and do not put the long code as 99% of the viewers do not have enough time to read and debug your code. So put your question again without code and explain it little more what you want. like creating text file and inserting values in it from text boxes or what ever is your requirement
or wait for the 1% guys if they found this code they might debug it for you.

i want to create a random file in vb.net ...where i can insert, update and search data ...help
|
|
|
|

well I guess you want to work in file system. as there is nothing in my vocabulary called "Random File" . I suggest you to use XML which is supported well by Dot net and is good according to your requirement

If you created the dll on .NET platform, you will still need to have .net framework installed on the target machine. Here is a sample class that's exposed to COM. You will also need to register the dll with regasm.exe utility found in %windir%\microsoft.net\framework\v1.1.*.
You can use this library in vbscript or vb6 (or any other COM client) simply with:
Set demo = CreateObject("Demo.demo") 'notice the ProgId below
Here is a link with some more explanation: http://www.codeproject.com/dotnet/nettocom.asp?df=100&forumid=14076&exp=0&select=1028513[^]
Imports System.Runtime.InteropServices
Imports System.Text
<guid("e3928d8b-4eca-42c1-81cf-482f1c18b5f7"), interfacetype(cominterfacetype.interfaceisidispatch)=""> _
Public Interface _demo
<dispid(1)> Function GetString(ByVal strString As String) As String

Public Function GetString(ByVal strString as String) As String Implements _demo.GetString
Return "COM Sample"
End Function
End Class

Some parts of the class got stripped off when i submitted it (because of the < tag), so it won't work. But look at the link above, it has more in depth information.

Hi
When you want to write your class in C#, try adding a ComClass rather than a simple class. (the ComClass should be availabe in Project>AddNewItem if I remember correctly.
Then make your dll file, C# would register the class for you and then you can simply use your class on your machine using CreateObject.
(to use the class on an other machine, you must first use regasm.exe as told to you.)
Hope it was helpful.

formula=Sum ({@DebitBalance})
Why above function cause error "This field cannot be summarized"
Actually @DebitBalance has value of number. Any ways that i can sum up @debitbalance?
|
|
|
|
|
Is {@DebitBalance} a formula too?

yes, inside that is :
if Sum ({Entries.Debit}, {Entries.AccountName})>Sum ({Entries.Credit}, {Entries.AccountName}) then
formula= Sum ({Entries.Debit}, {Entries.AccountName})-Sum ({Entries.Credit}, {Entries.AccountName})
end if
|
|
|
|
|
Although the formula always returns number, I don't think you can sum it. The Crystal Report couldn't recognize it as number. You have to look for another solution.
