No, that's not possible.
Something like this can only be done with static libraries that are linked with an executable.
With dlls you don't get code copied or linked directly, but only references to external functions.
That's the whole point of using dlls.

Maybe you can buy an enterprise version of obfuscation and then obfuscate your assembly. It might confuse the crackers when reverse engineering your assembly.
And i don't think you achieve with what you want.

There is a messy way of embedded B.dll in A.dll as an embedded resources, extracting it using Assembly.GetManifestResourceStream, and then loading it into the AppDomain using several different methods depending on how you extract it or to where you extract it...but that's just dumb.
Why? For one, it creates a servicing hastle. Now you have to patch both by virtue of patching A.dll. Also, anyone else can extract it using outside code.
If you're worry about disassembly or decompilation, then you picked the wrong language. .NET languages and Java both compile to intermediate code (.NET to Intermediate Language (IL), and Java to bytecode). Even if you obfuscate it some can deobfuscate it just as easily.
If you truly want to hide an implementation, then you'll need to put that functionality into a native DLL (which still isn't impossible decompile, though extremely difficult expecially when optimized) and use P/Invoke or COM interop, which you can read more about in Interoperating with Unmanaged Code[^] in the .NET Framework SDK.

Hi , I am trying to liken the ListView to a dataGrid..
Lets say we have a dataTable and a ListView..
In order to simulate dataGrid , we would like to known how many colums do we have , before binding the items into the ListView , I create the columns...
<br />
for ( int j =0 ;j<dTable.Columns.Count;j++)<br />
{ <br />
this.listView1.Columns.Add(dTable.Columns[j].ColumnName,-1,HorizontalAlignment.Center);<br />
}
Then , I consider to bind each dataRow into the ListView with the corresponding columns..
<br />
for ( int i = 0 ; i<dTable.Rows.Count;i++)<br />
{<br />
this.listView1.Items.Add(dTable.Rows[i][0].ToString());<br />
for ( int j =0 ;j<dTable.Columns.Count;j++)<br />
{ this.listView1.Items[i].SubItems.Add(dTable.Rows[i][dTable.Columns[j].ColumnName].ToString());<br />
}<br />
}<br />
Do you have any idea what I am doing wrong ?

You're adding the column name over and over again ?
It would help if you said what is actually GOING wrong. Why are you using a listview if you want a datagrid ?

Thanks for the reply ,
May be because of the style of the text , you cant see right , I only add the columns to the listView in the first loop, then I add values to those columns..
well it seems like , the values are ok , by this code..But I guess , I made the ListView nervous , treating like a dataGrid.May be you are right, I was just looking for fun , and develop some UI skills...
<br />
StringBuilder s = new StringBuilder();<br />
foreach (ListViewItem li in this.listView1.Items)<br />
{<br />
s.Append(li.Text);<br />
for(int k =0;k<this.listView1.Items[li.Index].SubItems.Count;k++)<br />
{<br />
s.Append(this.listView1.Items[li.Index].SubItems[k].Text);<br />
s.Append("-");<br />
}<br />
s.Append("\n");<br />
s.Append("------------------------");<br />
s.Append("\n");<br />
}<br />
<br />
MessageBox.Show(s.ToString());<br />

ok , At last I found the reason, ColumnHeader Collection can not be work with listView(or I cant do it)
<br />
ColumnHeader [] h = new ColumnHeader[ColumnCount];<br />
<br />
for (int i=0;i<ColumnCount;i++)<br />
{<br />
<br />
h[i].Text=dTable.Columns[i].ColumnName;<br />
<br />
}<br />
this.listView1.Columns.AddRange(h);<br />
After I declare ColumnHeader one by one , it works fine..
Do you see any syntax or algorithm errors in Column Header Collection that I created?

it's not a collection, its an array as you have created it using array syntax.

Thanks this approach worked, here is the code for C#
System.Windows.Forms.PrintPreviewDialog printPreviewDialog = new System.Windows.Forms.PrintPreviewDialog();
System.Windows.Forms.ToolStrip toolStrip = (System.Windows.Forms.ToolStrip)printPreviewDialog.Controls["ToolStrip1"];
toolStrip.Items["PrintToolStripButton"].Available = false;

Hi,
I'm interested in learning how to retrieve CD information from a CD Drive in C#. I really only require the volume ID, to begin with. I suppose I can learn the rest myself once I've taken the first step.
Can anyone tell me the best way to learn how to do this?
eg.
- DLL References
- Classes
- Other URLs to sources that explain this
Many Thanks!
Tim

Sorry, I meant TOC, not volume ID

I have the following problem: i was trying to write a simple console application where the user enters a number and the program must show that number, as you can see is VERY VERY SIMPLE! but when the user enters the number, C# takes a wrong number, and gives that as the answer, here's an example of the code:
int i=0;
console.writeline("Enter a number: ");
i=console.read();
console.writeline("Your number is {0}",i);
i don´t know what the problem is, cause as far as i know I'm using a method that works for that!
Can anybody help me, please?
|

I think you should look at the return value of console.read() method , this method is for reading the next character , for not reading an integer..
string s = Console.ReadLine();
then cast the string into an integer value
int readInt=int.Parse(s);
console.writeLine("Your number is {0}",readInt.ToString())
the above code will read the int , and then show the user...
as I know..Hope it will work..

how can i use the serial port and treat with it
using c# to pass characters to it

Hi,
Look at the kernel32 writefile function.
There are many examples out there on communicating with serial port.
Hope it helps.
Cheers.

I am looking to dynamically generate a value (which will be shown in a textbox) depending on which rows in a datagrid are selected, rows may be selected/deselected by the user and the value will change dynamically depending on certain fields in the selected rows. Iterating through the rows to find which ones are selected is not my dillema, the problem is that I cannot find an event that fires when a row in the datagrid is selected/deselected. I would rather not force the users to click a "calculate" button. It seems that a "RowSelected" event on the datagrid would make most sense, but I cant find any info on such functionality!! I suppose I could use the "OnMouseUp" event, but then the user would be forced to use the mouse to select rows, no shift/ctrl + arrow keys!.
Any suggestions?
Thanks,

DateTime d = new DateTime();<br />
d=dateTimePicker.Value;<br />
d.ToShortTime();
after you pass the value into a DateTime variable , you could choose which format you would like to bind..
|
|
|
|
|
you can also do:
DateTime dtEnd = new DateTime();
dtEnd.CustomFormat = "yyyy";
this.dtEnd.Format = System.Windows.Forms.DateTimePickerFormat.Custom;
