Automatic update. Check the version number of the external program. Administrator permission. Multiple startup prohibited. code obfuscation, version number permission

Automatic update. Start program a. Check the version number of program B. Then upload and download the program on the server. To control the version number of other programs, check the version number of other programs. inconsistent versions will send text messages to developers.

URL corresponds to the server address. http://ekaipiao.gingkoo.com/clients/GingkooPrint (142.16.exe

The Client is followed by a relative path

Private void start ()

Process p = new Process (); // create a Process
P. StartInfo. FileName = Application. StartupPath + @ "\ Print.exe"; // set the process name
P. StartInfo. CreateNoWindow = true;

}

Program B starts program

 

File = GetRequestDownFile ("http://ekaipiao.gingkoo.com/clients/Service.ini", Application. StartupPath + @ "\ Service. ini ");

Download the server version number. If it is later than. download the latest version to overwrite

Guaranteed speed. The server stores the new version of ZIP files. The client downloads and decompress the files in the background to start.

FastZip fastZip = new FastZip (); // decompress the object

FastZip. ExtractZip (Application. StartupPath + @ "\ relase for Win7 or above.zip", Application. StartupPath, null );

 

// FastZip. ExtractZip (@ "D: \ test1.zip", @ "D: \ decompress directory", null); // decompress

// FastZip. CreateZip (@ "D: \ document .zip", @ "D: \ source directory", true, null); // Compression

Lossless

 

Start ();
Process [] proc = Process. GetProcesses ();
Foreach (var item in proc)
{
If (item. ProcessName. Contains ("AutoUpdate") // vshost
{
Item. Kill ();
}
}

 

Start the target program and you will be able to kill yourself.

 

How to detect external programs. Check the Registry. If it is a green software, read the desktop shortcut. If it is full of computers, search for it.

 

Private List <string> shorttopsean () // Desktop Search
{
List <string> data = new List <string> ();

String dir = System. Environment. GetFolderPath (System. Environment. SpecialFolder. Desktop );

DirectoryInfo dirInfo = new DirectoryInfo (dir );

FileInfo [] files = dirInfo. GetFiles ("*. lnk", SearchOption. TopDirectoryOnly); // the current directory
List <int> test = new List <int> ();
Foreach (FileInfo file in files)
{
Data. Add (file. DirectoryName + "\" + file. Name );
// Data. Add (AppDomain. CurrentDomain. SetupInformation. ApplicationBase + file );
}

Return data;

}

All shortcuts on the computer will be found. The EXE on the desktop is actually lnk

Private string VersionSean (string item) // check the version number
{
IWshShortcut _ shortcut = null;
IWshShell_Class shell = new IWshShell_Class ();
If (System. IO. File. Exists (item) = true)
_ Shortcut = shell. CreateShortcut (item) as IWshShortcut; // obtain the physical path through shortcuts

Var path1 = _ shortcut. TargetPath;

FileVersionInfo. GetVersionInfo (Path. Combine (path1 ));
FileVersionInfo myFileVersionInfo = FileVersionInfo. GetVersionInfo (path1); // obtain the version number through the physical path

Return myFileVersionInfo. FileVersion;

}

Private string WindowsVersionSean ()
{
String windowsversion = null;
OperatingSystem OS = Environment. OSVersion;
Switch (OS. Platform)
{
Case PlatformID. Win32Windows:
Switch (OS. Version. Minor)
{
Case 0:
Windowsversion = "Windows 95 ";
Break;
Case 10:
If (OS. Version. Revision. ToString () = "2222A ")
Windowsversion = "Windows 98 Second Edition ";
Else
Windowsversion = "Windows 98 ";
Break;
Case 90:

Break;
}
Break;
Case PlatformID. Win32NT:
Switch (OS. Version. Major)
{
Case 3:
Windowsversion = "Windows NT 3.51 ";
Break;
Case 4:
Windowsversion = "Windows NT 4.0 ";
Break;
Case 5:
Switch (OS. Version. Minor)
{
Case 0:

Case 1:

Break;
Case 1:

Break;
}
Break;
}
Break;
}
Return windowsversion;
} // Check the Win version

Why check the Win version number. This is the auto update part, because WIN7 and xp cannot use the same source code.

 

Var a = shorttopsean ();

Foreach (string item in)
{
If (item. Contains ("VAT invoice tax control invoicing software (tax control disk version). lnk") // baiwang
{
Revoke Wang = VersionSean (item );
}
If (item. Contains ("invoicing software. lnk") // airline mail
{
Hangxin = VersionSean (item );
}
}

 

In this way, you can read the version number of the external program.

 

[DllImport ("kernel32")]
Public static extern long WritePrivateProfileString (string section, string key, string val, string filePath );
[DllImport ("kernel32")]
Public static extern int GetPrivateProfileString (string section, string key, string def, StringBuilder retVal, int size, string filePath );

 

GetPrivateProfileString ("VersionData", "Key", "", temp, 500, file); // read

 

WritePrivateProfileString ("VersionData", "Key", temp. ToString (), Application. StartupPath + @ "\ Client. ini"); // write

 

This method can be used to operate the INI file.

Why? Because the version number is in the server's INI

If the version number of the external program on the client is detected to be inconsistent with the version number stored on the server, send a text message and send an email to inform our developers of the external program upgrade. See if there is any impact ~

 

Public static string GetHtmlFromUrl (string url)
{
String strRet = null;
If (url = null | url. Trim (). ToString () = "")

{
HttpWebRequest hr = (HttpWebRequest) WebRequest. Create (targeturl );
Hr. UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1 )";
Hr. Method = "GET ";
Hr. Timeout = 30*60*1000;
WebResponse hs = hr. GetResponse ();
Stream sr = hs. GetResponseStream ();
StreamReader ser = new StreamReader (sr, Encoding. Default );
StrRet = ser. ReadToEnd ();
}
Catch (Exception ex)
{
StrRet = null;
}
Return strRet;
}

Call the SMS Interface

You can send five text messages for free ~
