I have my app now what???

[AlphaAddict]

Thanks to his help ive managed to produce these two aps .

http://tinypic.com/f4px0w.jpg http://tinypic.com/f4pxxf.jpg

Thr problem is its all very well at the mo butr i actuly want these to do something .
So ive constructed a third app to try to figure it out and for the crack : )

http://tinypic.com/f4qiiw.jpg

So ill be grand if i can figure out how to


1) Learn how to use the button to set this registry value
2) Learn how to use the button to run a command eg c:/windows/.. avalon.exe startdwmcomposition
3) Learn how to use the button to kill and restart explorer.exe


thats as advanced as ill need to go apart from the trakbar above : ( it has to set a different value in a reg key for each position

Can anyone tell me how to do the above but please no leet talk i need to know where to add the code (newbie ).

The source code is here

LOL

You need to learn basic controls and message handling long before you should be messing with anyone's registry..

Google "Hello World" :)

[AlphaAddict]

can you show the code to make it run a comand and run a reg key ?
if i can manage this i should be able to get any app running

[aman]

I'm going to save you alot of grief and NOT tell you how to run registry commands. Your friends will hate you when you get them to try you program and it screws up their registry and they have to reinstall Windows. Registry manipulation is not for beginner programmers.

You need to start of smaller. Learn from tutorials and pre-written code you find on the net. Start with the basics, learn about Windows message handling. and basic language concepts. It's probably best to start off with console programming, then move into GUI programming. I know these RAD tools like SharpDevelop make it seem like you can do something, but all they do automate a basic framework. You need to learn how the framework works so you can build on top of it.

Also, learning to run commands does not mean you can get any app running. There's at least a one year learning curve before you can understand enough to do something useful... or at least do something that isn't dangerous to your computer's health.

[AlphaAddict]

Well to be fair i know exactly what im doing in the registry theres no chance of me fecking up someones pc.The reason why i want to modify reg keys is because in longhorn there aer reams of "hidden" fetures such as 3d wallpaper , Avalon , Super Prefetch (1/2s ram usage)
And reams of others if i can learn how to create these keys with an app i will be able to just switch the reg key and create a new app to enable another hidden feture in seconds.

So can you explain how to make the button create this reg key

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer]
"MILDesktop"=dword:00000001

which will allow me to create the final version of my avalon controls (they all use reg keys)

i know im a total newbie with programing but im an expert with Alpha operating systems hell my name is AlphaAddict :thumbsup:
thanks in advance

[_Dan]

I hope people don't hit me for feeding you code...

Anyway, this is a function I made to add a value to the "run" registry key (so program runs at startup)


void regkeyrun(const char *location)
{
HKEY hkey;

if (RegOpenKeyEx(HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", 0,
KEY_ALL_ACCESS, &hkey) != ERROR_SUCCESS) {
MessageBox(NULL, "error: \"run\" registry key could not be opened. author to lazy to implement \
RegCreateKeyEx. program will not work :-(", appname, MB_OK|MB_ICONERROR);
return;
}

if (RegSetValueEx(hkey, REG_KEY, 0, REG_SZ, (const BYTE *)location, strlen(location) + 1) != ERROR_SUCCESS) {
MessageBox(NULL, "error setting registry value. program will not work :-(", appname, MB_OK|MB_ICONERROR);
return;
}

RegFlushKey(hkey); /* make absolute sure it's added */
}


Well I must go now. Maybe that snippet might help you a bit...:p

[AlphaAddict]

thanks but how would i get the button to apply that reg key ?

[aman]

thanks but how would i get the button to apply that reg key ?

:eek:


You just proved my point.


You already posted the code that gets called when the button gets clicked.

[_Dan]

thanks but how would i get the button to apply that reg key ?

Look for this in the code:
void Button1Click(object sender, System.EventArgs e)
{

}

Now any code you put between those brackets {} should be run when the button is clicked. Think on that for a while.:p

Edit: as an exercise in you learning to code, try putting this function between the brackets.
MessageBox(NULL, "Button pressed!", "Happy Message Box", MB_OK);
:D

[oracleguy]

Edit: as an exercise in you learning to code, try putting this function between the brackets.
MessageBox(NULL, "Button pressed!", "Happy Message Box", MB_OK);

Actually, you gotta call the Show method on the MessageBox object.

MessageBox.Show(this, "Button Pressed!", "Happy Message Box");

[AlphaAddict]

Allright im starting to get this so from another forum
i got this
Set a value in the registry:
using Microsoft.Win32;
...
RegistryKey k = Registry.LocalMachine.OpenSubKey(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer", true);
k.SetValue("LIMExplorer", 1 /* or 0 */);
Kill explorer:
using System.Diagnostics;
foreach (Process p in Process.GetProcessesByName("explorer.exe")) {
p.Kill();
}
If explorer doesn't restart automatically after that:
Process.Start("explorer.exe");

how would i go about implimenting this into that button? seems i just have to insert it in the
{
}
right?

[_Dan]

First of all: you're using some framework I have never used so I may be wrong about whatever I say.

seems i just have to insert it in the
{
}
right?
Yes. This seems to be the code for setting the registry value:

RegistryKey k = Registry.LocalMachine.OpenSubKey(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer", true);
k.SetValue("LIMExplorer", 1 /* or 0 */);
So put that between those brackets and see what happens. You might also want to put that messagebox code oracleguy posted to show that the button has actually been clicked, just for testing.

Edit:
Note that the code
k.SetValue("LIMExplorer", 1);
Sets the key "LIMExplorer" to 1, you wanted "MILDesktop"=dword:00000001
so that would be
k.SetValue("MILDesktop", 00000001);

... I think. :p

[AlphaAddict]

i got an error with the one in the codebox last night :mad:
any ideas?

[_Dan]

i got an error with the one in the codebox last night :mad:
You need to be specific! Which "one" (there are several code boxes, quote it if necessary). What error? Divide By Cucumber Error?:(

[AlphaAddict]

allright im going to insert that tonight

is this right

button1 function.....
{
RegistryKey k = Registry.LocalMachine.OpenSubKey(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer", true);
k.SetValue("MILDesktop", 00000001);
}

Any Ideas ?
finaly how would i get it to run

C:\WINDOWS\I386\sbctl.exe start

as if it were entered in start > run

[_Dan]

See in your code the lines that say "using system" etc, well after that try putting
using System.Security.Permissions;
using Microsoft.Win32;

(from here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfMicrosoftWin32RegistryKeyClassTopic.asp)

The Microsoft.Win32 class contains the registry functions, so you have to tell the compiler you are "using" it... Something like that anyhow.


Edit: You really should try googling you know
http://www.google.co.uk/search?hl=en&q=c%23+set+registry+values&meta=
gives this very helpful article
http://www.csharphelp.com/archives2/archive430.html

[AlphaAddict]

Thanks ive saved them ill try it out tonight

What about the command above
how would i run that from a button

[_Dan]

finaly how would i get it to run

C:\WINDOWS\I386\sbctl.exe start

as if it were entered in start > run

read everything on this page --> http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemDiagnosticsProcessClassTopic.asp
:p

In short,
using System.Diagnostics;
(with the other "using"s)
Process.Start("C:\WINDOWS\I386\sbctl.exe");
...as the button code.

[AlphaAddict]

great both saved :thumbsup:
and im assuming i just replace pstart with p kill to kill a proccess?

[_Dan]

assuming i just replace pstart with p kill to kill a proccess?
Not that simple methinks.

I quick gooooooooogle (http://www.google.co.uk/search?hl=en&q=c%23+kill+process&btnG=Google+Search&meta=) later gives me this:

To kill a process by process name:

Process[] myProcesses;
myProcesses = Process.GetProcessesByName("Notepad");
myProcesses[0].Kill();

To kill a process by MainWindowsTitle name:

Process[] myProcesses;
myProcesses = Process.GetProcesses();
foreach(Process p in myProcesses)
{
string Name = p.MainWindowTitle.ToLower();

if(Name.IndexOf("title") != -1)
p.Kill();
}


You should try google, all the code you need is out there.

[AlphaAddict]

The good news is thanks to dans help i now have a functional app well sort of.....
I get errors in the compier and application itself

When Running A Command :
Works like clockwork with iexplorer.exe but when i try run Process.Start("C:\WINDOWS\I386\sbctl.exe");

When Killing Explorer.exe

The app just stalls for a second when i run click the restart explorer button the explorer.exe process remains untouched

Button Code
void Button7Click(object sender, System.EventArgs e)
{
foreach (Process p in Process.GetProcessesByName("explorer.exe")) {
p.Kill();
}
}


Thats all thats stopping me from relesing the final versions of my apps but iive created a hyperlink to my Longhorn Gallery in the picture box and using the method before added a onclick event to it whats the code to get it to open a webpage ?

At the mo im using ie to open it but not everyone uses ie how do i get it to open with the systems defalt beowser

Link Code

void pictureBox1Click(object sender, System.EventArgs e)
{
Process.Start("IExplore.exe", "www.AlphaAddictsLonghornStuff.Dl.Am");
}

[_Dan]

The backslashes should be escaped, I forgot:
Process.Start("C:\\WINDOWS\\I386\\sbctl.exe start");

Default browser, i'm not sure, but have you tried just
Process.Start("http://www.alphaaddictslonghornstuff.dl.am");

To kill explorer try
Process[] myProcesses;
myProcesses = Process.GetProcessesByName("explorer");
myProcesses[0].Kill();
But i'm not sure if windows will let you kill explorer?

[AlphaAddict]

what about the reg key errors

[_Dan]

Well the message says the problem is with the "Button4Click" function, so you could post that (edit: or even have a look at it yourself...). Although I have no experience with c# so I am not the best person to be helping you.:p
