The only way your user can write to that key is if they run your application as an administrator.

No, your not. Admin level accounts are still running as normal users, until you need the Admin level access. Right-click the app's icon and pick "Run as Administrator" to really run it as an admin.

Hi,
I have found a idea for Creating registry entry in HKEY_LOCAL_MACHINE in Vista whether UAC is enable.
You can use Exe with MANIFEST as admin Previleges. Or Run the programme as Administrator.

Good luck with that. I highly suggest creating a normal user test account on the machine and testing your application under that account instead of the one you used to develop the app under.

First, it's not "urgent". Second, you seem to have something leaning on the "z" key. Remove it please.
It looks like your connection isn't really opened. You may want to check for this before you call your Execute method or single step through your code, line-by-line, checking what's happening yourself.

Personally I would not waste my time trying to get it right. I would use one of the dev libraries that are available that sit on top of Tapi and give you the VB.Net interface.
This[^] is one of them that I have heard of. The guy that runs the company has tons of Tapi experience and this seems to be a solid product from what I have heard. It runs across a wide range of hardware.
One word of advice from a 'telephony guy'... What you want to do, done RIGHT, needs the proper hardware. Yes you can use a modem and get away with it but if you really want to do proper call progress detection then use the hardware that was meant for it. That means spending a little bit on the telephony interface hardware but your results will be much better than trying to use some 'el cheapo single line modem device that a lot of folks try to get away with.

I have one MDI forms & several child forms in my application. When i am opening child form in MDI from , its open perfectly, but when MDI form is resizing, it does not showing scroll bar & i am unable to see whole child form.
In child forms, border is none & control box is invisible.

You Can Use TableLayoutPanal for adjusting your form in MDI form.Use Tablelayoutpanel Dock Propery to Fill in MDI.

Without reading through your code I have a couple of points that may be relevant.
1 You are using sql strings - you should be using stored proc.
2 I would use datatables for every single one of your cmd.executereader. A datareader maintains the connection while you are procesing the data, a datatable is disconnected from the connection as soon as you complete the load.
Never underestimate the power of human stupidity
RAH

i didnt use datatable because the table is too large. but suddenly i realize i can just "select top 1" =_=
btw, will this solve the problem of memory leak?

If you're looking at TaskManager to see the memory statistics, you're looking at the wrong stats. TaskManager is showing you about how much memory is reserved by the .NET CLR that is running your app. It is NOT the amount of memory your app is actually using.
If you want to see much more accurate stats, use Performance Monitor instead. There are a bunch of .NET Memory counters you can look at that won't "lie" to you.

|
|
|

but it's actually the sqlserv.exe that use up the memory. it reach above 1GB if i continue to run the program. i try to run the code in debug mode, if i stop it, it wouldn't free up the memory also.

If the memory usage is in SQL Server, then you need to optimise your SQL and how you call SQL Server to limit memory usage.

Thx. But what should i do? How to optimize?
FYI, i 've change to use sqldataadapter, it seems to use less memory, but still it wont free up after used.
and btw, as can seen from my code, i used oracle reader too. it does not have any problem.

Well, one way would be to write a bunch of SQL so you send it all at once and get a single dataset back instead of using readers over and over for every result you want.

Make sure that you dispose all the disposable objects that you use. I see at least one OracleCommand object that you leave open and undisposed. As you do this in a loop, that's one connection for each selected item.
Don't call GC.Collect. The garbage collector knows better when a garbage collection should be done.

sorry for misleading. Actually it's the sqlserv.exe that use up the memory. My oracle.exe is working fine. MICROSOFT ......

It's normal for SQL Server to use any available memory for caching, that is the default setting. If you are running the SQL Server on the same computer as the application, you have to limit the amount of memory that SQL Server uses, so that there is some left for the application.
Normally it takes days or weeks until SQL Server uses all available memory, but as you are fetching everything everytime in your query, it will go a lot faster.
Verify that you close and dispose everything, not just the one object that I found at a quick read-through. I also see an SqlCommand object that you leave open and undisposed. That means that one connection is left open for each selected item, which uses a bit of memory for buffers, and also keeps the result in memory as you leave it unread. The connections will time out after a while, but you are probably running into problems before the timeouts starts to free up enough connections.
Despite everything, the person most likely to be fooling you next is yourself.

i've tried to do some testing. this is my testing code
Dim sqlCOn As New SqlConnection("Server=localhost;Database=phxtest;Trusted_Connection=yes")
Dim sqlda As SqlDataAdapter
Dim sqldt As DataSet
Dim sqlFieldCount As Integer
sqlCOn.Open()
Dim SqlCommand As New SqlCommand("select top 0 * from msaspot", sqlCOn)
sqlda = New SqlDataAdapter(SqlCommand)
sqlDt = New DataSet
sqlDa.Fill(sqlDt) ## Here is where it use up the memory ##
sqlDa.Dispose()
sqlFieldCount = sqldt.Tables(0).Columns.Count
sqldt.Clear()
sqldt.Dispose()
SqlCommand.Dispose()
sqlCOn.Close()
sqlCOn.Dispose()
