ya OS doesnt allow u to hide ur deamon fron process viewer......

If it runs; It can be cracked!
That's a phrase i saw in a article about protecting software from crackers, and I'll use it here.
(Besides if it's not possible, how is the anti virus software doing it?)
Some time ago i developed a administrative application, and i wanted to implement a feature that would allow the boss to hide the process from the end users 'Task Manager' so they wouldn't kill it.
After some research, i learned that this was only possible with low level Windows API's, something I'm not that comfortable with.
There is basically two main idea's behind this, 1) hiding the process just from task manager, this requires hooking the massages that pass from Task Manager to Windows, then modify the result to exclude your process. 2) install a low level windows driver that monitors the internal windows process list and removes your program's entry.
Needless to say, method 2 is much more effective then method 1 but less stable, and knowledge of C programming is required to develop such a driver.
I hope thats enough info to give you a head's up for what to search for, and i hope your intentions are good ones.
Don't ask me for my results or code, I think if someone really needs to develop such an application he should know a lower level of programming, or be ready to break his head while searching for someone else's code.

My purpose of process hiding is, in my company have some computer that have time period for using so i develop software(VB.NET 2005) for automatic shutdown computer if it has been turn on befor xx:xx A.M. or after xx:xx P.M. and i need to hide this software process from process viewer. But if it can't perhaps i need to hide task manager from end-user.
:-DThank for all suggestion.

I'm using VB 2005 Express, and I'm looking for code that adds images to listview subitems (listview is in report view).
I've found C++ samples, like XListCtrl and Supergrid but I haven't a clue how to interpret them!
Any help much appreciated,

Hi there,
first of all thank you for your help in some of my previous questions. I have been able to work them out thanks to you.
I have one more question.
in my form i have a combobox and a listbox. now in my combobox i have attached the rest_type field of my database (types of restaurants available)
cbrest_type.datasource = dataset11.tables("Restaurants@) <br />
cbrest_type.displaymember = "rest_type" <br />
now if i want to list all the names of the restaurants that are of the same type in my listbox (by choosing it from the combobox), how can i populate it??
ex. i want to list all the restaurants that are al a carte in my listbox...
if you can supply me with code it will be fantastic as i have no idea on how to start :S

Let me give u a arough idea..
1. Bind the resturant type id with your combobox as well like,
cbrest_type.valuemember = "rest_type_id"
2. Get the selectedvalue from the combobox (in SelectedIndexChanged event of combo) to see which rest_type is selected. like cbrest_type.selectedvalue
3. Query the DB for that selected ID to find out the resturants for that ID.
4. Bind them with Listbox.

I have an order table in access.I want to print orders from 1 to 10 or like that.(values entered in two text boxes).I have created the crystal report,it is working smoothly when giving the range values.
But through Vb I wrote
orders.orderid>=value1 and orders.orderid<=value2
If I give value1=5 and value2=7 it is showing properly.I change the the value1 it is working.But if I change the value of value2 it is not refreshing.always the value of value2 remains the first value(the value given for the first time.)

Hi All,
We are porting the following VB 6 code in to VB.net
VB 6 Code:
NumChan = GetDppData(objDppApi, VarPtr(DataBuffer(0)))
Here GetDppData is the function declared as below
Public Declare Function GetDppData Lib "DppApi.dll" (ByVal objptr As Long, ByVal DataBuffer As Long) As Integer
Where DPPApi.dll is a registerable COM Dll.
VB.net code :
UseDll.DppApi.GetDppData(objptr, VarPtr(dp4DataBuffer(intMcaChannelCount)))
Where the above function is declared in a module with name UseDll as below
Public Declare Auto Function GetDppData Lib "DppApi.dll" Alias "GetDppData" (ByVal objptr As Integer, ByVal DataBuffer As Integer) As Integer
VarPtr function Definition in VB.Net is as below
Public Function VarPtr(ByVal o As Object) As Integer
Dim GC As System.Runtime.InteropServices.GCHandle = System.Runtime.InteropServices.GCHandle.Alloc(o, System.Runtime.InteropServices.GCHandleType.Pinned)
Dim ret As Integer = GC.AddrOfPinnedObject.ToInt32
GC.Free()
Return ret
End Function
Here the functionality that we are woking is :
We are passing the Address of array to the dll so that it can fill all the array elements using Base address of the array.
The VB 6 code is working fine.
In the case of VB.Net code array is not getting initialized.
Please Guide me How to proceed

Hi All
I hope someone can help with this.
I want to be able to load a file into VB.NET 2005 and return the first 11 integers from the file.
I found ReadAllBytes to load the information into memory.
Dim returnValue As Byte()<br />
returnValue = My.Computer.FileSystem.ReadAllBytes(txt_Path.Text & "\" & filename)
What I need to do now is to read the memory to return the value of the first 11 integers into a list box, either as numbers or as hex, so I can check the information in them.
I have seen lots of examples of ReadAllBytes being used but none getting any information from the file.
Or am I wanting to use ReadAllBytes in the wrong way?
Regards
Simon
