first the user keys in something in the textbox and then he press enter on the keyboard.. after enter key is pressed, i want to move to tabPage6..
this is what i did:
private void button3_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar==(char)13)
{
this.GetNextControl(button3,true).Focus();
tabControl1.Focus();
tabControl1.SelectedTab=tabPage6;
e.Handled=true;
}
}
but when i run the app and i press enter, tabPage6 is not displayed.. only when i click on the button it will be displayed..
thanks again for your kind attention! =)

Of Course !
because you but the code that move the focus in command button3 keypress event handler
nidhelp wrote:
private void button3_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs
so to make this happen when key pressed in textbox you must handle keypress event so you have two choice
after subscribe to textbox keypress event like you did in commandButton pass button3_KeyPress to it like the following
this.textBox1.KeyPress += new stem.Windows.Forms.KeyPressEventHandler(this.button3_KeyPress);
or create new function and copy the code in command button
keypress event in it so the subscip line will be like this
this.textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.textBox1_KeyPress);
Note:1-you dont have to write this code visual studio
will write it for you all you will do that you select to use existing function or new one
2-in your case you dont need this line of code
this.GetNextControl(button3,true).Focus();
Remove it or comment it by write // before them

Hello everyone!
I;ve been searching everywhere and tried everything and I can't find a way to do the following
assuming i have the following xml element
<e1>
some text here <e2> blah <e2> hello <e3/> another set of text
</e1>
what happens is:
i have a string array of the 3 strings (some text here, blah, and another set of text)
i have another array of 3 objects (e1, e2, e3)
but they are separate... if i want to process them they wouldnt be in order because the order is lost as they are in different arrays..
Any ideas?
Thanks,
Michael

You have to check the "Do not treat <'s as HTML tags" checkbox when you write your message, to make the xml code visible. Now it is treated as broken html, so the tags doesn't show up in the message.

sorry, first post

The xml is broken (or you made a typo?). There is no end tag to the e2 elements.
When does it happen? What do you do? What are you going to use it for?
The xml is not formed in a good way if you want to process the data in it. If you parse the xml, you will get text elements mixed with elements. Similar to:
<e1>
<>some text here </>
<e2> blah </e2>
<> hello </>
<e3/>
<> another set of text</>
</e1>
where the <> elements represent text elements.

I want to display a float on a WinForm, but this only gives an int. Why?
SomeFunc(graphics g)
{
...
float x = 0.0f;
Font theFont(....);
//more stuff...
....
//->HERE!!
g.DrawString(x.ToString(),...
}
Why do I get "0" and not "0.0"?
thanks in advance....

You did not specify a format string with the ToString() method, so the default formatting in the current culture with minimum number of characters is used.

Rob,
Thanks for your response. I must admit I'm a bit lost.. Here's my code:
////////////////////////////////////////////////////////////////
//Label x axis.
Font graphFont = new Font("Arial",8);
Brush graphBrush = new SolidBrush(Color.BlueViolet);
float x = 0.0f;
String xString = x.ToString();
for(float gx = xIndent; gx <= graphRect.Width; gx += gx)
{
g.DrawString(xString, graphFont, graphBrush, this.ClientRectangle.Left + xIndent, yOrigin + 4);
}
//////////////////////////////////////////////////////////////////
What will give me "0.0" instead of "0"?
-thanks again

String xString = x.ToString("F1"); //format as floating point with 1 digit to
right of decimal point using the current culture.

You must specify the format by calling the System.Single.ToString(string format) overload.

Hopefully I am missing the point here, I have a simple question about public functions/classes
Lets says I create Widget application X, due to the complexity of the application the design dictates that some of the functionality should be farmed out into various DLLs. So now I have:
MainWidgetApp.exe
WidgetHelper.dll
WidgetHelper.dll has various Public functions/class that can be referenced by the main app. Once this setup gets deployed out into the real world there is nothing to stop another developer making a reference to the public functions/classes in the DLL.
So the question is how can I stop this from happening whilst still being able to keep the design of an Exe dependent on various DLLs
post.mode = postmodes.signature;
SELECT everything FROM everywhere WHERE something = something_else;
> 1 Row Returned
> 42

Use an obfuscating tool after deployment. I also know of an application from Microsoft Research that will merge all your .NET assemblies into a single assembly, which can improve startup performance (as there is overhead involved in loading assemblies).

Well, the other developer won't have the docs, altough he can still see the classes and methods with something like .NET Reflector.
You could implement some kind of authentication, making the app generate an aunthentication ticket that is validated every time in the DLL's methods.
Is it really necessary? You could obfuscate your DLLs, so the other developers won't understand the code if the open the DLL in .NET Reflector.

Its not so much about obsfucating the code
The situation I am in is that I have a helper DLL that does alot of work with XML for an application I produced.
The company I work for has found out that other companies are using the public interface of this DLL to perform processing on their own data.
Obviously we want to stop this, but would prefer to keep the exe and helper dll seperate as it is also used by other applications.
The only solution I can think of, is as you suggested, some type of session/ticket validation but before embarking on that project I was wondering if there was another way
post.mode = postmodes.signature;
SELECT everything FROM everywhere WHERE something = something_else;
> 1 Row Returned
> 42

The way I'm going to explain is a little crazy...
You can mask the DLL with some other filename (such as Filename.dat) and crypt it with, for example, a 3DES algorithm (provided in .NET Framework!). After this a some kind of bootstrapper is needed to decrpyt, rename, install the DLL in the GAC and start the main application. When the application is closed, the boostrapper removes the DLL from the GAC.
to install the DLL in the GAC you can use the utility provided with the .NET Framework.
My solution is ingenious, isn't it?

This I am curious about, I wasnt aware that it was possible to control the GAC programmatically. Can you post up some more information
post.mode = postmodes.signature;
SELECT everything FROM everywhere WHERE something = something_else;
> 1 Row Returned

The utility name is gacutil.exe, you can find it via-code in %windir%\Microsoft.NET\Framework\v1.1.4322\gacutil.exe
to install an assembly in the GAC use the command
gacutil /i "Assembly Path"
for example gacutil /i "D:\Projects\MyPrj\Release\bin\MyLib.dll"
to remove it
gacutil /u AssemblyName
for example gacutil /u "MyLib.dll"
It isn't complicated.
To improve performances you can install the assembly in the GAC with the ngen.exe (you can find it in the same directory of gacutil) utility. That program translates the assembly in a native image (i.e. an exe or dll file containing only machine-level code).
To di this, use the command:
ngen "Assembly Path"
for example ngen "D:\Projects\MyPrj\Release\bin\MyLib.dll"
to remove it you can use ngen and gacutil both.
the first way is
ngen /delete MyLib.dll
the second one is
gacutil /u MyLib.dll
to run those commands via-code (C#)
System.Diagnostic.Process.Start("Exe Path", "Arguments);
To avoid console is shown, you should learn more about Process class.
I hope I've been helpful.

Does it really need to be in the GAC? If not, don't put it there, just do this to the assembely in the directory where your application lives.
Of course, it wouldn't take a rocket scientist to capture the dll while the app is actually running, then copy it elsewhere for later use. Or even get it accidentally if the app quit under abnormal circumstances (eg. was killed with TerminateProcess()).

the problem is that you cannot copy assemblies from the GAC because it is not a phisical directory! go to %windir%\assembly\GAC and try to copy a file from there. Use the command prompt also.

Wanna bet? You just need to know where to look.
Anyway I don't think any directory is a physical directory. Nothing in software is "physical." Of course, there are physical magnetic dipoles that are pointing in one direction or another, or transistors that have in particular electrical states and those are physical properties, but the concepts of files and directories are more metaphorical than physical.

I tried to go to %windir%\assembly with windows explorer, and it doesn't allow you to copy assemblies.
I tried to go to the same dir with the command prompt, and the 'dir' command lists some assemblies (without extension!), but the 'copy' command doesn't work.

And your company doesn't have any lawyers to stop this? If you already know it why not bring those other companies to court?
