C# - C# Discussion Boards

Hi,

I am creating a setup project for my solution in C#, and I created a merge module that include all obfuscated assembly files (.dll files, and the .exe file), then add it to the setup project

Before building the setup project, I replace assembly files (in the Bin/Debug) by obfuscated files. After building the project, .dll files still are obfuscated, however the .exe file isn't obfuscated.

Are there anyone know how to fix that ?

Thank you very much !

I suspect, from this question, that you are manually obfuscating the file. When your setup is built, though, it rebuilds the executable, so that the file is no longer obfuscated - (you'll see the same behaviour if you manually apply a certificate to your code). The trick is to run the obfuscation process as a PostBuild process - which means that the setup will get the obfuscated version.

I was brought up to respect my elders. I don't respect many people nowadays.

Thanks Pete very much,

Could you please tell me more how to use PostBuild process ?

I'm using the Crypto Obfuscator software to obfuscate assembly files.

And I can see the properties of Setup project include the PostBuildEvent but I don't know how to use it (I am using Visual Studio 2010)

Thanks and regards,
Tai

Have a look at this[^]

Hi Pete, thank you

Could you tell me more detail about creating obfuscated setup project ?

My solution includes some project:
1. Start up project (create application file)
2. Library projects (create dll files)
3. Merge project (include obfuscated assembly files)
4. Setup project

Thanks and regards,

Hi, You can drag and drop the project file to Eazfuscator.Net and it will handle the Obfuscation of your binaries every time you compile with release, if you are using different Obfuscator check how to obfuscate the project file, I believe rebuilding your solution is recompiling the .exe and overwrite your Obfuscated .exe then the setup project will include the new non-Obfuscated file.

Thanks Samer,

I am trying to use Crypto Obfuscator and Dotfuscator. I only rebuild setup project (not the solution) but it make the .exe recompiling. I don't know why ?

how to perform update and delete operations on a grid view in which the data is already bounded on the time of page load

here is my code:

Hi,
This question looks like ASP.Net not C#, you might get a better answer, if you ask this question under ASP.Net category

Think! Don't write a line of code unless you absolutely need to.

I thought I would show you guys a quick tutorial on how to build native cocoa apps using C# and MonoMac. I will be showing you how to make the famous "Hello World" app.

Lets Begin!

You will need the following:
MonoDevelop IDE
MonoDevelop Framework SDK
XCode 4.x

One you have those, open up MonoDevelop. Click on "new solution" Drop down the C# category and select "Mac (open source)" and create a MonoMac project.

Now once that is done you should have some files and folders. Double click the MainWindow.xib file and XCode should open. Add a button and a label. Now click the middle button above Editor in the top right of XCode. Find "Automatic" and click on it and go to "MainWindowController.h" Now right click and drag the button to the code and add an outlet called "guiButton" or whatever you want. Do the same with the label. Now right click and drag from the button again but this time select action and name it "buttonClicked."

Ok, that's done. Save and close XCode. Now go back to MonoDevelop and open MainWindow.designer. A bunch of new code should have been added. Verify that the outlets and action have been added before continuing.
Your file should look like this:

// WARNING
//
// This file has been generated automatically by MonoDevelop to store outlets and
// actions made in the Xcode designer. If it is removed, they will be lost.
// Manual changes to this file may not be handled correctly.
//
using MonoMac.Foundation;

namespace dontgivemeerrors
{
	[Register ("MainWindowController")]
	partial class MainWindowController
	{
		[Outlet]
		MonoMac.AppKit.NSTextField guiTextField { get; set; }

		[Outlet]
		MonoMac.AppKit.NSButton guiButton { get; set; }

		[Action ("buttonClicked:")]
		partial void buttonClicked (MonoMac.Foundation.NSObject sender);
		
		void ReleaseDesignerOutlets ()
		{
			if (guiTextField != null) {
				guiTextField.Dispose ();
				guiTextField = null;
			}

			if (guiButton != null) {
				guiButton.Dispose ();
				guiButton = null;
			}
		}
	}

	[Register ("MainWindow")]
	partial class MainWindow
	{
		
		void ReleaseDesignerOutlets ()
		{
		}
	}
}

Ok, now open MainWindowController.cs and find "#endregion" Go under it and add the following line of code:

C#

partial void buttonClicked (MonoMac.Foundation.NSObject sender)
{

}

Replace "buttonClicked" with name of your action. Now for the final step. Add this to that line of code:

C#

partial void buttonClicked (MonoMac.Foundation.NSObject sender)
{
     this.guiLabel.StringValue = "Hello World";
}

Now run the app by pressing the icon with 2 gears and a green gear on the top right of MonoDevelop. Press the button and the label text should change to "Hello World."

Thats it. Most of your code will be under the action void. To find your .app file, go to YourUserName -> Projects -> NameOfProject -> NameOfProject -> bin -> Debug

Happy Coding! Smile | :)

I believe you are asking about Face Detection and Face Recognition. There are many great articles here on CodeProject, so put those terms into the Search box and see what you can find.

I will start you off by presenting some of the articles I really like.

This is one of the best articles, but the source code is in C++:
Face Detection C++ Library with Skin and Motion Analysis[^]

Another great article focused on the technical aspects:
Haar-feature Object Detection in C#[^]

This great article is focused on making a program using existing libraries:
Multiple face detection and recognition in real time[^]

Best of luck

                                Win32.SendMessage(parent.vScrollBar.Handle, (uint)message.Msg, message.WParam, message.LParam);
                            }
                        }
                        break;
                    }
            }
            base.WndProc(ref message);
        }
    }
}

In the above code, I did the following 1. created a NativeWindow to catch the messages of combobox listcontrol by assigning combInfo.hwndList handle. 2. Placed my custom scrollbar(ScrollBarEx) in the non-client area of combobox listcontrol.

But my custom scrollbar(ScrollBarEx) doesn't receives any messages or focus. It looks like it is dead. Please look into this code and share some idea to make the scrollbar live.

Probably not the answer you are looking for, but Win32 / Winforms scrollbars are extremely tricky to skin. Win32 / Winforms in general is extremely tricky to skin well. It would behoove you to move to WPF for this. The entire concept of WPF is that everything can be easily skinned without you having to write any C# code (assuming you are not changing behavior). All done via XAML.

Sorry I can't switch to WPF. Is there any idea to achieve this in winforms?

Oh well. In that case, you are in for a world of hurt lol Smile | :)

. The common controls interact with the *real* internal window scrollbar, not your external scrollbar control, so you need to customize the internal one. The internal window scrollbar is not a control, but rather painted as part of the WM_NCPAINT process, so you'll need to override that and do all your own painting for the ENTIRE non client area.

BE WARNED: There is a major gotcha that people don't know about until they try to implement this. I only know about it because I've done it in the past Smile | :)

...

You [B]***CANNOT***[/B] achieve custom scrollbars without API hooking. No way, no how, no workaround that. Reason being is that Windows implements the scrollbars like this:

case WM_NCPAINT:
{
// random code to do random stuff
DrawScrollBars();
// more random code to do random stuff
break;
}

Now, thats all well and good, you could override the WM_NCPAINT message and prevent the stock DrawScrollBars() function from getting called.

However, the internal scrollbar functions that the common controls use do not go through WM_NCPAINT Smile | :)

, they call DrawScrollBars() directly and there is no way to bypass that without API hooking Smile | :)

.

So what you'll get is you'll get your pretty new scrollbars 75% of the time and the stock scroll bars flashing through 25% of the time.

Like I said, switch to WPF Smile | :)

(or find an API hooking library).

My c# console app calls a managed c++ dll. The dll is added as a reference to the c# project. If I try to start in debug mode it says error while trying to run project. unable to start program, unrecognized error in windows web service framework. It is not a web application. If I run without debugging, the console pops up and my dll produces an error that the hdf5 header files don't match the hdf5 library my c++ dll is linked to (though it compiles and builds just fine). Both c# driver and c++ dll are 64 bit on a 64 bit machine. Both the F5 and ctrl F5 errors are puzzling. Any ideas what i should do to fix?

if (e.KeyCode == Keys.Enter && (sender as TextEdit).Text.Trim() != "")
{
    this.Cursor = Cursors.WaitCursor;

    is_form_exists = false;

    foreach (Form search_resul_form in this.MdiChildren)
    {
        frmSearchResult search_form = search_resul_form as frmSearchResult;

        if ((string)search_form.Tag == "BROWSE_PATIENTS")
        {
            // search_form.Activated(null, null);
            search_form.find_what = "FILE";
            search_form.find_text1 = (sender as TextEdit).Text.Trim();
            search_form.find_text2 = null;
            search_form.browse_result();
            search_form.Activate();
            is_form_exists = true;
            break;
        }
    }

    if (is_form_exists == false)
    {
        frmSearchResult SearchResultForm = new frmSearchResult(public_var);
        SearchResultForm.Tag = "BROWSE_PATIENTS";
        SearchResultForm.MdiParent = this;
        SearchResultForm.Dock = DockStyle.Fill;
        SearchResultForm.find_what = "FILE";
        SearchResultForm.find_text1 = (sender as TextEdit).Text.Trim();
        SearchResultForm.find_text2 = null;
        SearchResultForm.Show();
    }

    (sender as TextEdit).Text = "";

    this.Cursor = Cursors.Default;
}
