I have an old dll created in C++ with Visual Studio 6.0 with the Win32 Dynamic link-library project. Is it possible to use that dll in a .NET, C# project?
If, How? I’ve tried to add a reference in VS 2003 to the dll but I got the error that the dll is not a .NET assembly or a COM dll…

Hi,
I've read the article about Ethernet packet sending and tested the code. All is great. I try to make the same work over windows CE. It's possible to adapt the code for my scope?
Many Thanks

Hi all,
I want to generate a report (a CV) with an individual Fotos (Bitmaps) on it. I am using the "pull method" and a XML-Database structure for crystal reports, but loading the report by a dataset.
Does anyone know how to do that (how to tell crystal reports that the field object is a variable bitmap)
and which format to use for on the dataset to supply the correct information ?
Thanks
Frank

I've got a line chart with the date displayed horizontally across the x axis and would like to display the dates vertical. Is there a way to rotate the group labels on the x axis?

I am wanting to setup a window in an application I am working on that behaves similar to the Find and Replace windows in Visual Studio where the modeless dialog remains above the main application's window at all times not covering other application's windows. I have tried the TopMost property, but it overlaps other application windows as well which I don't want. Is there a way to implement a topmost-like behavior that doesn't overlap other applications' windows? 
Thanks in advance.

Im not 100% sure but I think setting the Owner property of the dialog to your application main form should do it.

That did it! Thanks!

In a C# application:
How to delete a file in a non-permanent manner by sending it to Recycle Bin, instead of deleting it permanently?
I want to do it so that the user will have the option of restoring the file from Recycle Bin if he wants to at a later time.

You need the Windows Shell API for this.
Use the SHFileOperation.

Thanks for reply.
But, is it possible to get the "physical address" of the Recycle Bin "virtual" folder in the C# code itself, because in that I can use the File.Move method to move the file to that folder. This may be equivalent to deleting to the Recycle Bin.

normally it is located under C:\RECYCLER\ + Some string that looks like an SID.
But i think it is not recomendet to move files directly into this folder since you would override the maximum size of the recycler. This could lead to conditions where the recycler grows until it uses all the space of the HD.
But since the recylcer is only available on windows you could use the shell functions. you app would work only on windows anyway.

I want to use this dll inside some my different applications.
How can i do?

Create a project as a class library,and compile it using the library arguments ,it will be then a dll file ,add a reference to it in any application that you want to use it in.

I've got a slight problem with @-quoted strings in C#. I'm reading some XML formatted data using a XmlTextReader. At some point in this process I get a chunk of text that contains some escape sequences. I want to use this as the format part in an StringBuilder.AppendFormat() method.
StringBuilder sb = new StringBuilder() ;<br />
string format = myXmlTextReader.Value ;<br />
sb.AppendFormat(format, ...) ;
However the value in format is @-quoted. If I look in the debugger it shows the following:
format = @"The user says\n{0}"
I just can't work out how to un @-quote the string in code. I want the newline in the string not the \n. There must be a simple way to do this but I just can't find it!
TIA Jackson

Er... it IS unquoted.
It is only displayed as verbatim string (otherwise it would contain a CR that wóuld not look so nice in the IDE's watch window).
Do not use the debugger but try a Console.Out.WriteLine(format); to verify my claim.

The debugger always shows all strings verbatim. Try printing to the console and see if it works correctly.

Well - I've added the following two lines to the app:
System.Console.WriteLine(format);<br />
System.Console.WriteLine("test\nstring");
And this produces the following in the Output Window:
The user says\n{0}<br />
test<br />
string
Just to confuse things further before I display the final string from the StringBuilder I looked at the value in the string and the debugger shows the following:
msg="Test Dynamic Form\nLess than 20 users impacted\nNo you can't\nNO VALUE SELECTEDThe user says\\nTest"
The debugger does not show the @ for a @-quoted string this time and the final \n has been escaped! It isn't escaped when its in the variable format - just to be sure i replaced all occurances of \ with ! and printed out the result.
So - still confused here

Oops. My bad. The debugger doesn't show all strings verbatim, it shows them only for
1. those that have the @ and have escaped characters, for eg, @"senthil\n".
2. those that don't have an @ but still have escaped characters, like "senthil\\". "\n", "\t" seem to be exceptions to this rule.
Anyway, your problem is because format has a literal \n in it, that is, format = @"The user says \n". You'd need to search for the literal \n ("\\n" or @"\n") and replace it with the line breaking character. In short
string x = @"senthil\n";
string y =x.Replace(@"\n", "\n");
Console.WriteLine(y);
will do what you want.

Senthil

Senthil,
Yes - this does indeed solve the problems for newlines, and is the route I had started down. However the issue with this approach is the I have to code up a method that knows about all of the escape codes and transforms them. I was hoping to find a method that didn't require that I capture this information in code.
However I can't think of anything better and it should be possible to write a big regexp that covers of the escape sequences I want to allow.
Thanks for the help

I don't think XML data that is read can contain linebreaks, as the XML parser ignores linebreaks and spaces between tags (NOT for attribute values though). So I think you have to anway convert literal \n s to linebreaks anyway.

I'm not sure I completely understand your problem. However, I gather you simply find it a nuisance to have to write an extra / mark in your code. I made a little utility a while ago, that if you paste any text you want to send to a textbox, you simply paste or enter the text you want formatted. Then click process, and it inserts all the slash marks, and etc. Then you paste that code into your application, and voilla, you can have the text programmatically inserted into a textbox or richTextBox. idk if it's useful or not, but you can download it here (I find it handy for entering multiple lines of code):
http://www.teched.coe.ohio-state.edu/lugnut/stephen/Text%20Formatting%20Revealer.zip
if it helps you any let me know. I'm aware the output is somewhat sloppy, nevertheless it works with 100% functionality as far as I've tested it.
good luck solving your problem,
Stephen

Hi!
Is it possible to index textboxes? What I mean is: instead of having TextBox1, TextBox2 and TextBox3 have something like an array of textboxes - TextBox(1), TextBox(2), TextBox(3) - and be able to accessed them with, for example, a FOR statement:
for (int i=0; i!=4; i++)
{
TextBox(i).Text = "hello";
}
Thank you for helping!

Yes it is, but obviously you won't be able to use it from the designer.
You can create them like
class MyForm : Form
{
private TextBox []boxes;
public MyForm(int count)
{
boxes = new TextBox[count];
foreach(TextBox box in boxes)
{
this.Controls.Add(box);
}
}
}
Regards
Senthil
