Your question still has nothing to do with Windows Development, and Dave has already given you a link to find the answer.

In a LAN with many computers, only a few computers when I set static IP computer is not connected to the network but I set dynamic IP the computer works normally, how to fix this error ?
|
|
|
|

Assuming that you have got DHCP server in LAN which is responsible for automatic ip addresses assignement.
When you set static ip and its address is out of range of your DHCP, you can't connect to the internet.

I configured static IP is of course the full input already, you have not read my information carefully, in the LAN there are many computers set static IP works well but only a few machines can not set the static IP to Dynamic IP works, of course when I set a static IP that doesn't have duplicate IP but it still doesn't work
|
|
|
|
|
And what range of IP addresses is reserved for dynamic assignement (on DHCP server side)?
What IP are you trying to set manually?
What error message do you get?
In my opinion, when you set static IP addresses, you provoke IP address conflict

But you have not provided the information necessary. What are the actual values of the IP addresses that work and thos that do not, and what addresses are configured by the DHCP?

I am using a DrayTek Vigor 2925 modem, the LAN address range I set is as follows:
From address: 192.168.1.2-> 192.168.1.9: used for servers, cameras, timekeepers, ...
I use dynamic IP and static IP from the address: 192.168.1.10-> 192.168.1.210 = DHCP = enable server
When I set a static IP, the computer did not report an IP conflict if the IP was not used, only a few computers could not access the network when I set the static IP to any of the addresses in the range: 192.168.1.2-> 192.168.1.254, My company has 70 computers, including 4 computers I can not assign static IP, I do not understand why ? I have installed 4 new computers, but I can use it for about a month to get stuck

I suggest you contact the modem manufacturers for assistance. This question has nothing to do with Windows development or programming.

I think the operating system is more Windows than ADSL modem

That may be true, but it is still not a programming issue.

Have you tried disabling DHCP completely, for all computers, and using hard addresses alone for all devices? Remember, any third party anti-virus programs worth their salt have access to these hard addresses and will allow user access to particular features of their third-party interface which will target those addresses. And checking there will show, whether or not there was ever any error on the part of either Windows or the AV, any discrepancy that sounds like the type you're experiencing.

I login win7 with the "administrator" account and password: xxx, my computer is the server to share the printer to other computers on the LAN, if I change the password of the "Administrator" account then the computer Other computers on the LAN will not print. If I create a "PrinterShare" account and a yyy password to share the printer, when I log in to win7, there will be 2 accounts: "administrator" and "PrinterShare", I don't want to share the printer account when I log in appears, how do I do it ? or I use an "administrator" account that still shares the printer, but I am allowed to change the password as long as the computers on the LAN do not know my password when sharing the printer.

What does this have to do with writing code for Windows?

Thank you very much for just helping me.

Background: There are vulnerable kernel mode drivers for Windows systems, which can be loaded into the system for various purposes. Loaded kernel mode drivers leave traces in the system. Anti-cheat software for video games, for example, look for vulnerable driver traces in various parts of the system because they are used for cheating. The logic used by anti-cheat software could perhaps be (or were already) used by anti-rootkit tools or rootkits themselves.
I am wondering where traces are left after drivers are loaded and then unloaded. From my research, I found these two places in Windows NT kernel, where unloaded drivers leave traces:
1. PiDDBCacheTable
2. MmUnloadedDrivers
(Just to let you know, those are undocumented data structures)
Where else could they leave traces? Is it possible for me to learn it without reverse-engineering the Windows kernel by myself?

I just searched several dozen .msi files, one by one, using Orca to extract the ProductCode from the Property table. It was cumbersome, and I made a couple mistakes when copy/pasting the values. I will have to repeat this task (for a greater number of msi files) at irregular intervals.
I wish I had a tool to echo the selected attributes from a given table in a file (sort of Select Value from Property where Property="ProductCode") - either as a library or as a complete program so I can traverse a directory tree and apply it to all (relevant) msi files.
This time, I needed the ProductCode from the Property table, but later I may want any attribute from any table in the file(s), if it exists.
Does any such program or library exist?
(I do not have resources to dissect e.g. the Wix source code to learn the database structure inside .msi files!)

I do something like that all the time. I just wrote a small VBScript to return the ProductCode in an InputBox. It's easy enough to do.
I added the script to the context menu for .MSI files. Now I just right-click an .MSI and click "Get ProductCode..." Done.
It's very unlikely you're going to find any such tool as you describe. It seems specific to your situation only, so you're probably going to have to write your own tool to traverse your directory tree and gather the specifics you need.

Traversing the directory tree is trivial - I once made a general mechanism for that, and use it all the time (for listing files not accessed for x days, for listing dependencies of Python pakcages, for counting lines of code, for creating warnings about paths that are getting close to the old 260 char limit,...). To this directory travesal function, I supply one or more search roots, filters (such as Extension = "msi"), and a callback function that receives each file that passes the filter. An optional callback handles directory hits, or directories with file hits.
So that part of it is in place. My problem is how do I make that callback function with "a small VBScript to return the ProductCode"? Which mechanism did you use to obtain that value? Is that script available?
The only way I am aware of to read out the ProductCode (or any other .msi value) is to use the GUI application "Orca". At least as a GUI application, it is poorly suited for callback function. It seems to be callable from a script, but the help information gives no help on how to extract a given attribute from a given table. How did your VB script read out the values from the .msi file?
I am programming in C#, but I guess that I could adopt the same mechanism. If I cannot rewrite it to C#, I can run it as a separate process and analyze the console output (I do that all the time, for my other tree traversal functions).

To get the ProductCode in VBScript is easy:
Dim msi,database,view1,record,productCode
Set msi = CreateObject("WindowsInstaller.Installer")
Set database = msi.OpenDatabase(WScript.Arguments(0), 1)
Set view1 = database.OpenView("SELECT `Value` FROM `Property` WHERE `Property` = 'ProductCode'")
Call view1.Execute
Set record = view1.Fetch
If record Is Nothing Then
MsgBox "Unable to find a ProductCode in the MSI database!"
WScript.Quit
End if
productCode = record.StringData(1)
Set record = Nothing
view1.Close
Set view1 = Nothing
Set database = Nothing
Set msi = Nothing
InputBox "The ProductCode is:", WScript.Arguments(0), productCode

I found one answer myself: The WiX toolset included dark.exe that translates an .msi file into an XML file. Extracting an arbitrary attribute value from XML is a trivial affair.
So my problems are solved.

My WiFi drivers have not been functioning well lately. They stop working and don't display any error indication until I try to disconnect/connect, and the network I'm on is alone in the network taskbar thing. Sometimes the driver even vanishes without a trace, and I need to reinstall it/restart my laptop to get it working again.
-My laptop is a Lenovo X220
-I run Windows 7 (Professional, I believe)
-My WiFi drivers (I have tried multiple) are Intel
-I know that it's a software issue, as I changed the hard drive between laptops (the same model) and there was no difference.
Any help at all is much appreciated, and this problem is very annoying when I'm trying to play online with .
