Hi Bernard, thanks again for the reply.
The DLL projects are built for x86 and the test application was built for AnyCPU. I've been of the understanding the x86 will work on x64 without issue, so I've no reason to suspect the DLLs in this case. I used the AnyCPU option for the test as I assumed I could then use a single test.exe to test either x86 or x64 builds of the DLL. But are you tell me this isn't the case?

Yes, x86 works fine on x64. The problem is that you cannot mix 32- and 64-bit code in the same process, which is what it appears that you're doing.
Your .DLL's are all 32-bit and since you compiled the app that uses them as AnyCPU, it'll run as 64-bit on a 64-bit machine. You have to go into your project properties and, on the Compile tab, change the TargetCPU to x86.
The bitness (architecture-SA!) must match between your .EXE and your .DLL's. If you compiled the .DLL's as AnyCPU, it would have worked.

Hi Dave,
Thanks for the reply, and as a result I am wiser now than I was 5 minutes ago. I've built the test.exe as x86 and all is well. So the whole thing was down to my misunderstanding of the "AnyCPU", a lesson learned and a mistake I hope never to repeat.
Thanks.
Bubba

You need to look into the use of obfuscators[^], although none is 100% effective.

Obfuscators will help you hide code. But there is no absolutely fool proof way of doing this.

hi
i create a custom datagridviewtextboxcolumn inherits from my control (that it inherits form textbox by some feature . for example limit to numberonly)
in my custom column I overrides onvalidating to check entered numbers before moving to another cells
my code is here :
Protected Overrides Sub OnValidating(e As CancelEventArgs)
If AllowNull = False Then
If String.IsNullOrEmpty(Me.Text.Trim) = True Then
e.Cancel = True
MessageBox.Show("لطفاً اطلاعات را وارد نمائید", "ارزیابی اطلاعات", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
Select Case InputType
Case Inputs.NationalCode
If ValidateNcode(Me.Text.Trim) = False Then
e.Cancel = True
MessageBox.Show("لطفاً کد ملی را بصورت صحیح وارد نمائید", "ارزیابی اطلاعات", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
Case Inputs.Numbers
If AllowNegative = True Then
If ismatched(Me.Text.Trim, negshregex) = False Then
e.Cancel = True
MessageBox.Show("فرمت اعداد صحیح نمی باشد" & vbNewLine & "حداکثر طول اعداد صحیح 15 رقم" & vbNewLine & "و حداکثر طول اعداد اعشار سه رقم می باشد", "ارزیابی اطلاعات", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
Else
If ismatched(Me.Text.Trim, shregex) = False Then
e.Cancel = True
MessageBox.Show("فرمت اعداد صحیح نمی باشد" & vbNewLine & "حداکثر طول اعداد صحیح 15 رقم" & vbNewLine & "و حداکثر طول اعداد اعشار سه رقم می باشد", "ارزیابی اطلاعات", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
End If
Case Inputs.Decimals
If AllowNegative = True Then
If ismatched(Me.Text.Trim, negshregex) = False Then
e.Cancel = True
MessageBox.Show("فرمت اعداد صحیح نمی باشد" & vbNewLine & "حداکثر طول اعداد صحیح 15 رقم" & vbNewLine & "و حداکثر طول اعداد اعشار سه رقم می باشد", "ارزیابی اطلاعات", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
Else
If ismatched(Me.Text.Trim, shregex) = False Then
e.Cancel = True
MessageBox.Show("فرمت اعداد صحیح نمی باشد" & vbNewLine & "حداکثر طول اعداد صحیح 15 رقم" & vbNewLine & "و حداکثر طول اعداد اعشار سه رقم می باشد", "ارزیابی اطلاعات", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
End If
End Select
End If
End Sub
when my custom column is in editing mode and I click by mouse to another place or cell ,if value of cell not matched , validating fired and prevent to move to another cell until user correct entered data. but when I press ENTER or Tab , validating showing message 2 time and move to another cell and don't prevent move to another cells
why press enter or tab not calling validating event ?

Hi,
Thanks everybody for the response to OnInitDlg equivalents. I now override 'OnLoad', and that got me started. What I'm now looking for is the equivalents for:
-CWnd::ShowWindow(SW_HIDE);
-CWnd::ShowWindow(SW_NORMAL);
I use:
namespace SgCntr
{
public partial class LogOn : Form
{
private void button_Exit_MouseClick(object sender, MouseEventArgs e)
{
this.Hide();
string message =
"Are you sure that you would like to Terminate \n"
"the Softguard Sales Terminal Application?";
const string caption = "Application Terminating";
var result = MessageBox.Show(message, caption,
MessageBoxButtons.YesNo,
MessageBoxIcon.Question);
if (result == DialogResult.No)
{
this.Show();
return;
}
this.Dispose();
}
}
}
The this.Hide() doesnot just hide the logon box, but the entire application.
-CWnd::EndDialog(nDlgResult);
I use the Dispose method in the above sample, which returns 'DialogResult.Cancel'.
How do I make it return an int of my choice.
Thanks,
Bram van Kampen

Your logon form should be a separate but 'normal' form with labels, textboxes and buttons, as built with the designer. Then at the appropriate point in your main program you launch it by LogonForm.ShowDialog(), and you have a MFC-type modal dialog on the screen. When the user clicks the OK (or whatever) button, you just capture the inputs into your local variables, in the same way that you would in the OnOK() function in MFC. Something like:
this.Hide()
LogonForm lf = new LogonForm()
result = lf.ShowDialog();
variable = lf.textbox1;
When lf goes out of scope it will dispose itself so you do not need to.
Use the best guess

Thanks Richard,
that clarified some aspects of the problem. Maybe I should slightly rephrase.
As soon as I call:
result=lf.ShowDialog();
the dialog (or form) goes into some modal loop. I need to break out of that by clicking OK or Cancel. In other words, the handler code for the clicked button needs a method of breaking out of the modal loop.
N.B.Falling out of scope is a COMPILE time issue, never a RUN time issue. When execution reaches the closing scope brace, it will hit a compiler generated code block that carries out an effective cleanup and garbage collection. This would include (unlike MFC) that the Form Classes still displayed are automatically removed from the screen.
The form cannot fall out of scope while it is in the modal loop, and would remain on display forever. I used 'Dispose();' to break the circle, which on this occasion does the trick of breaking out of the loop. I am aware that this is not the proper way. For one, in doing so, lf is no longer available for interogation, and the line:
variable=lf.textbox1
would throw an exception.
In MFC I would use OnOK(), OnCancel(), or sometimes even EndDialog(nResult). How do I break out of the modal loop from within say a Button Event handler in C#.NET.
Kind regards,
Bram van Kampen

I think you misunderstand where the scope of the object starts and ends. The code snippet I showed you is the way to do it. When you press the OK button of your dialog, the dialog's window is no longer displayed, but the dialog object still exists, so you can extract the data from its components. For example:
void someMethod()
{
this.Hide()
LogonForm lf = new LogonForm()
result = lf.ShowDialog();
variable = lf.textbox1;
}

I understand where the scope of an object starts and ends, I just do not know the names of the base class handlers which are (or should be) called when either the OK or Cancel button is clicked.
I used Dispose(), not because I did not understand scope, but, because it was the only method (I know it is the WRONG one) I could find that at least removed the window, and broke out of the modal loop.
I also want to find out how it is all wired up.
In de SDK we had the WindowProc, in MFC we have the MessageMap to tie events to handlers, what do we have in C#.NET? A Click on a Button event gets somewhere attached to the handler for that event. how and where?
An event handler can decide to terminate the modal loop and thereby return from ShowDialog. (how? what base method does it call to accomplish this). In other words, in MFC we have 'EndDialog' to get out of the modal loop. What do we have in C#.NET to do this?
Thanks for your time and interest,
Regards,
Update- Stop Press,
Somewhere in Stackoverflow:
"but, I know that setting DialogResult closes the form! everyone knows that!".
Well, I did not know that! One of those surprises! It would take some gymnastics in MFC to do that! At the same time, I do not think that many MFC programmers would be happy about such development.
It is where thing are organised entirely differently than what an MFC programmer in his innocence would suspect. What also does not help that everything in C#.NET has an entirely different naming convention.
Anyway, I tried it.
this.DialogResult = DialogResult.Cancel;
Closed the Dialog, and left it available for further interrogation.
The other queery stil stands. this.Hide()( called in the LogOn button handlers) hides the entire application, and not just the LogOn dialog. Is this a feature of the debug mode, or an error on my part.
Thanks again;

Yes, totally wrong; you should have a button on the form that returns a DialogResult. If you click on a button on your form and look at the properties you'll see how you can set it to return OK, Cancel etc. This will then perform graceful closure of the form and return to your code.

Not sure about this, I would need to run some more tests; if time allows I'll give it a try some time over the weekend.
[edit]One thing I would suggest is that you clear MFC from your mind. MFC and .NET may look similar but there are many subtle differences which can catch you out. There are plenty of beginner articles around, I found them very useful when I first started with C#.[/edit]

I did have a bunch of similar public methods for converting an RGB structure to grey scale but decided it made the class too complicated so I changed them to private and created an Enum which was used as a parameter for a public method which then called those private methods method using switch.
One of the private methods then developed a need for a parameter, but only one of them. I made the parameter optional but then stumbled into the problem of public shared methods not being considered as constants, so I switched to overloading for this method and wanted to add an optional Enum to represent the two variants of that one method, this smelt bad. So I thought to use overloading again, but the second version of the method would still be able to accept all the options of the first Enum, even though only one was relevant, the one that needed the second Enum, still smelt bad.
I'm struggling to follow this explanation myself, so if code helps then here it is (simplified). I don't like it.
I could possibly use the second ToGreyScale method with just the LumaEnum parameter but that, to my mind, makes the use of the class problematic since it's not intuitive. Calling the second method GreyScalebyLuminosity makes a nonsense of trying to get rid of all those differently named GreyScale methods.
Is there a pattern I can use here? Or just a better design than this?
Public Overloads Sub ToGreyScale(ByVal method As RGBGreyScaleMethod)
Select Case method
Case RGBGreyScaleMethod.Average
Me.GreyScaleByAverage()
Case RGBGreyScaleMethod.BlueChannel
Me.GreyScaleFromBlue()
Case RGBGreyScaleMethod.Decompose
Me.Decompose()
Case RGBGreyScaleMethod.Luminosity
Me.GreyScaleByLuminosity()
Case Else
Throw New ArgumentOutOfRangeException()
End Select
End Sub
Public Overloads Sub ToGreyScale(ByVal method As RGBGreyScaleMethod, ByVal factors as LumaEnum)
Select Case method
Case RGBGreyScaleMethod.Luminosity
Select Case factors
Case LumaEnum.BT709
Me.GreyScaleByLuminosity(LumaFactors.BT709)
Case LumaEnum.BT601
Me.GreyScaleByLuminosity(LumaFactors.BT601)
Case LumaEnum.GIMP
Me.GreyScaleByLuminosity(LumaFactors.GIMP)
Case Else
Throw New ArgumentOutOfRangeException()
End Select
Case Else
Throw New ArgumentOutOfRangeException()
End Select
End Sub
Private Overloads Sub GreyScaleByLuminosity()
Me.GreyScaleByLuminosity(LumaFactors.BT709)
End Sub
Private Overloads Sub GreyScaleByLuminosity(ByVal factors As LumaFactors)
Dim c As Double = Me.Luminosity(factors)
Me._Red = CInt(c)
Me._Green = CInt(c)
Me._Blue = CInt(c)
End Sub
Public Enum LumaEnum
BT709
BT601
GIMP
End Enum
Public Enum
Average
BlueChannel
Decompose
Luminosity
Desaturate
Lightness
RedChannel
GreenChannel
End Enum

I tried twice, and got lost twice. Let's try it differently; you've seen how the different events in .NET all look similar, with two parameters? One could do something similar;
Public Class MyParamaterBase
Public Property Id As Guid
End Class
Public Class MyExtendedParameter
Public Property Title as String
End Class
Public Class SomeConsumingClass
Public Sub SomeMethod(TheParameter As MyParameterBase)
If TheParameter is MyExtendedParameter Then
Console.WriteLine((TheParameter as MyExtendedParameter).Title)
EndIf
End Sub
End Class

Ok, so instead of an Enum parameter I have a base class parameter which through polymorphism can take a derived type which carries the extra parameter information?
I guess I could do the same thing by using an interface as the parameter?
Thanks,

I think this is simply a variation on your suggestion (in effect), using a nested class.
Public Class Class1
Private _param As Double
Public Sub New(ByVal amount As Double)
Me._param = amount
End Sub
Public Property Param() As Double
Get
Return Me._param
End Get
Set(value As Double)
If Not value = Me._param Then
Me._param = value
End If
End Set
End Property
Public Function ToGrey() As ToGreyMethods
Return New ToGreyMethods(Me)
End Function
Public Class ToGreyMethods
Private _outer As Class1
Public Sub New(ByRef outer As Class1)
Me._outer = outer
End Sub
Public Sub Increase(ByVal amount As Double)
Me._outer.Param += amount
End Sub
Public Sub Decrease(ByVal amount As Double)
Me._outer.Param -= amount
End Sub
End Class
End Class
Module Module1
Sub Main()
Dim thing As Class1 = New Class1(10)
thing.ToGrey.Increase(5)
Console.WriteLine(thing.Param.ToString())
thing.ToGrey.Decrease(10)
Console.WriteLine(thing.Param.ToString())
Console.ReadKey()
End Sub
End Module
My only problem with this is that I can't seem to hide the nested class so one could be created at runtime manually rather than as a result of a call to ToGrey(), which starts to feel a bit messy or at least has the potential to get messy since I do.t know what would happen if, for example, you could do this.
Public Sub Example()
Dim thing as Class1 = New Class1(10)
Dim whoops as ToGreyMethods = thing.ToGrey()
End Sub
