I Want that My logic in my dll file should be hidden just.
|
|

There's no need to shout. However, a point to consider - it's pretty much impossible to hide your logic. If someone is determined enough, they will be able to get access to it. Even obfuscation only does so much - one of the biggest weaknesses of managed languages is the ease with which they can be reverse engineered.

Then don't use a managed language in .NET. This includes F#, C#, VB.NET, ...
Use C/C++ and it'll compile to a native code library. This STILL won't protect your logic but it will make it much more difficult to reverse engineer over going with managed code.

Thanks , But i need sample code and crud operation.

Then I am afraid that you will have to go and search for it yourself; we don't know what code you are looking for.

I have problem regrading C# to PHP communication. I have read many old posts here and after that i came to conclusion that i have to Use PHP SOAP Web service on server side to get interaction with c#.
Here is the code which i tried:
//webservice.php
configureWSDL('webservice', 'urn:webservice');
$server->register('getMessage',array('msg'=>'xsd:string'),array('return'=>'xsd:null'));
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA)? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>
//notify.php which containing function which is registered with webservice
//member.php getting message and displaying it. This will be message i want from C# code when ever i //click the button.
In 2nd part in Visual Studio 2012 i added web service reference of WSDL file correctly, and written following code for a button.
//c# code
private void button1_Click(object sender, EventArgs e)
{
localhost.webservice src = new localhost.webservice();
src.getMessage("Hello");
}
But when ever i click button and i saw member.php page nothing happens.????????
Still it showing "temp". I want this "Hello" should be shown whenever i click button.
Any help please?? I am worried wasted my whole week to learn this and now have limited time for my project. I shall be very thankful to you.
Regards,

Hi, I am making a software,in that want to change month of a datetimepicker using a textbox.
i.e. as i put 15 in textbox the value of the month of a datetimepicker is increased by 15months.
like current date is 05/10/2013
and when i put 15 in a text box...the value of datetimepicker is increased by 05/01/2015.
thanks..
waiting for your reply..

In the code that handles the change value event (you do not say what your UI is so I can't guess) you increment the datetimepicker value by textbox.text value in months
datetimepicker.value.addmonths((int)TextBox.Text)
[edit] Alright, alright use parse ot tryparse to convert the text value to an int! [/edit]

Try:
int months;
if (int.TryParse(myTextBox.Text, out months))
{
myDateTimePicker.Value.AddMonths(months);
}

We have a managed C# DLL registered for COM interop. This DLL can be called from either a managed or unmanaged application where the customer can control the size and position of the DLL. In our demo application, we use the following win32 API functions to call the DLL. The problem we're running against is that we're losing mouse functions on toolstrip menu items after clicking in the form, even though the hot keys will still work using the keyboard. All controls work initially until clicking on the title bar (which I omitted) or certain controls on the main form.
[DllImport("user32.dll")]
public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
[DllImport("user32.dll", SetLastError = true)]
public static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
private void btnAdopt_Click(object sender, EventArgs e)
{
hWndDocked = (IntPtr)FindWindow(null, "DLL-Title";);
hWndOriginalParent = SetParent(hWndDocked, this.Handle);
MoveWindow(hWndDocked, 125, 25, iWidth, iHeight, true);
}
Some of the DLL dropdowns we can make work by changing the Parent Handle below in close event:
SetForegroundWindow(Global.ParentHandle);
Hopefully my explanation is clear, but has anyone run across this problem? Is there a better way of setting and controlling the DLL handles without losing certain mouse functionality? How can I make this work or what am I doing wrong?
Thanks in Advance,
Rick

It's difficult to tell exactly what you are doing, but if you are changing the parent of an active window that could quite easily mean that all mouse clicks are being redirected to the wrong window.

Hi Richard,
Thanks for your reply! Our self contained DLL application is called from a client's application that needs to be run within their "form/app". In my Demo, I set their app as the parent by using SetParent win32 API, but then I lose the mouse clicks on several controls. So your description in your reply appears to be accurate.
Most of our controls are now working by using the win32 API, SetForegroundWindow(ParentForm.Handle), switching the handle of our form to their app handle, in the click events of the user controls; buttons, combobox, panels, grids, etc.
I still have a problem when clicking on a disabled button/control. Actually, every mouse click needs to be trapped and handled.
How do you get the mouse click of a disabled control?
Or is there a better way of doing this?
Thanks,
Rick

I'm not sure I understand what this is all about, there is no such thing as a self contained DLL application. A DLL is a library that provides classes and/or functions for an executable application. Also your description does not really explain what services your DLL provides to the client application, or why you are trying to switch around owners of windows.

You don't; it is disabled in order to prevent it receiving input.

Hi, I am developing an application which has a WebBrowser control.
By default WebBrowser uses Internet Explorer rendering engine.
Can we change it to Firefox or Google Chrome?
Thanks

A postfix expression evaluator works on arithmetic statements that take this form: op1 op2 operator . . . Using two stacks, one for the operands
and one for the operators, design and implement a Calculator class that
converts infix expressions to postfix expressions and then uses the stacks
to evaluate the expressions.
This is homework. But I completely could not understand what to do.
Please tell me what to do.

This is an exciting opportunity for you to really increase your programming skills and mastery !
I really can't tell you "what to do" since that would defeat the whole purpose of your education, but I can provide some "clues" that may be useful:
0. know that CodeProject is your friend [^].
1. talk to your teacher, and fellow students: if all the other people in the class are at the same level you are, then probably the others are also finding the problem difficult: ask their advice. if most other people in the class are very advanced compared to you, and the teacher, and your fellow students, are not willing to guide you, reconsider whether you are ready for this course at this time.
2. but, before you talk to your teacher, do the study required to make sure you have a sound knowledge of what infix and postfix notation is, what a stack is.
3. be aware that parsing (interpreting) infix notation of the standard form involves recursion. you have both the native operator precedence rules ... like "multiply before add" ... and the fact that the use of parentheses can change the order in which operators are evaluated.
Study hard, work hard, learn from your mistakes; accept that making mistakes is inevitable, and that acquisition of deep understanding and skill often involve the simultaneous development of both.
