hello,
I am trying to hide the actions buttons in the title bar of a window.
I use user32.dll and I do
var style = GetWindowLong(pHandle, GWL_STYLE);
style = (int)(style & ~WS_SYSMENU & ~WS_BORDERICON );
SetWindowLong(pHandle, GWL_STYLE, style);
result = SetWindowPos(pHandle, IntPtr.Zero, 0, 0, 0, 0, SWP_FRAMECHANGED | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER);
The problem is that this code is execute in a different thread not the same thread which start my window application, so the setwindowlong bloc my application.
Does someone has got an idea?
Thanks in advance

If what you are trying to do is remove the Minimize, Maximize, Close and Normalize buttons, then "Form.ControlBox=false" is what you want. Beware though, it will remove the system menu as well.

No the problem is that I start an application with Process.Start(file.exe)
I have no power on this application, I can't change controlBox
But I want to hide the actions buttons of this applciation window so I use user32.dll to do this
I am clear?

I think I see what you are trying, but I don't know if you can do it for any process - I certainly hope you can't as that would effectively give control of a process to another process. Not something I would realy want on my PC!

yes I understand.
But it's strange because when I did it in the same thread I can do it...

You can't do that. Calling those functions will only work in the process/thread that called it.
C# also does not support the exports required of the .DLL Injection technique that could do this. You'd have to write that code in C++.

please help this program will check if the letters inputted are any number of "X" in the beginning and then any number of Y or no Y at all in the middle then any number of X in the end both x in the beginning and end must be the same numbers if it is valid or invalid..
#Valid inputs:
xxyxx , xyx , xxxx , xxxyyyyxxx, xx, xxxxyxxxx,
#invalid inputs:
xyxx , xxyx , yyyyyy , y , xxxxyx, xxxxy, yxxxxx
i managed to get all of them into there proper validity except the input "xx", "xxxxxxxx", xxxx... if there is no Y in the input if will have an error of "index out of range exception was unhandled ,index was outside the bounds of the array".... please help me correct it please here are the codes........

First off, read the instructions at the top of the page, where it says "How to get an answer to your question"
Secondly, change the subject "help me pls..........help me with my codes" to something a litle more descriptive.
Then, enclose your original code in <pre>...</pre> (or use the "code block" bit above the input text area - it does the same thing). This preserves the formatting and make it a whole lot easier to read your code. Nobody is going to want to wade through your spaggetti manually matching brackets and indents.

You're right. I guess I took a look at it since I'm in good mood today

Ah, it's that time of year again.. you're right!

Seriously.. Simple debugging of this code should give you the answer. I'll give you a hint on where you should start to check your logics.
while (pew[x].Equals('x'))
{
if (x == len) break;
countx1++; x++;
}

im not good in c# ... what else is wrong? pls help
|

This is not about being a good C# programmer or not - you would get the same problems in C, C++ and Java as well since it is your logics that fail when you try to access an array index beyond the arrays length.
And like someone else commented, I think there is a lot easier way of achieving what you are trying to do..

Much better! But when I said "your original code" what I meant was "your original code" i.e. with the formatting and indentation still in, not stripped out by your previous post! Whacking <pre></pre>round unformatted code just makes it pretty colours...

I'd use a Regular Expression; but maybe your teacher wants you to do it the hard way?

I've written an addon for Firefox that I want to port to IE8. Unfortunately I'm having trouble getting to the right documentation and I've still not been able to figure out what language should I develop the BHO in. C++ or C#? Or are there other options too?
Any links to documentation and online resource that could help me would be appreciated.

Preferred?? No. C++ would be the "preferred" language since all of the header files for this only work in C++. Using C#, you'd have to recreate all the structures, contants, P/Invoke headers, ... yourself, by hand.

|

Thanks for the reply Dave.
Turns out that not only is C# not the recommended language, the recommendation is actually against using it. Only one instance of .net CLR will be loaded and if two BHO have conflicting versions of .net, one of them is going to be out of luck. Also, each tab will need to load the .net library making this an expensive operation.

Assembly.Load(...) requires to give the fully qualified name, so does it mean Assembly.Load(..) can load only assemblies present in GAC?
Can a Assembly.Load(...) method load a private assembly?

Nope, it can also load an assembly that's present in-memory[^] (as an array of bytes), and you can also load an assembly by giving a partial name[^]. This snippet from PIEBALDConsult may help;
System.Reflection.Assembly assm ;
name = System.IO.Path.GetFileNameWithoutExtension ( Filename ) ;
assm = System.AppDomain.CreateDomain ( name ).
Load ( System.IO.File.ReadAllBytes ( Filename ) ) ;

It is a nice snippet!!

LoadWithPartialName is deprecated. Don't use it.
It will happily load the newest version of the assembly that's available on the machine. If you think that's what you need, please think again. At some point in the future, this newest version is very likely to be incompatible with your app.
In fact, using LoadWithPartialName in a .NET 2.0 app will crash as soon as a newer .NET 4.0 version of the library is installed.

Thanks for mentioning it, it's also in the documentation that was linked to.

Yup. Even if all the signatures stay the same, something is bound to break sooner or later, and it's always best to be prepared.

It's not obsolete in 2.0, and I doubt that Microsoft will bring out 4.0 with a feature[^] that breaks a lot of existing code
