The code seems to work right
**************************************************
StreamReader SR;
FileStream FS = File.Open("myFile.txt", FileMode.Open, FileAccess.Read);
SR = new StreamReader(FS);
while((FileChar = SR.Read()) != -1)
{
viewS.Items.Add(SR.ReadLine());
}
SR.Close();
****************************************************
but the first character in every line is truncated.

Then it DOES NOT work right. Do as the other person suggested. You can't will the CPU to do something.

Hi,
I am kind of new to C# and in my app I want to call a Win32 Dll(say TestController.dll)...
The Dll fn goes like:
<br />
TESTCONTROLLERDLL_API int fnGetDiagnosticsData(int iscrn,int* iWindowsMonNo ,int * itype,char * cSerialNumber,int * len)<br />
{<br />
int ireturn;<br />
.....<br />
return ireturn;<br />
}
In my C# calss to call this dll, I refferd to some articles in google that suggested me to do as:
public class ControllerTest<br />
{<br />
private int iScreenNumber=0;<br />
[MarshalAs(UnmanagedType.I4)]<br />
private int iWindowsMonNo = new int();<br />
[MarshalAs(UnmanagedType.I4)]<br />
private int itype = new int();<br />
[MarshalAs(UnmanagedType.I4)]<br />
private int iLen = new int();<br />
[MarshalAs(UnmanagedType.LPStr)]<br />
private StringBuilder szSerialNumber = new StringBuilder(100,100); <br />
[DllImport( "TestControllerDll.dll", CharSet = CharSet.Unicode )]<br />
public static extern int fnGetDiagnosticsData(int iscrn,[MarshalAs(UnmanagedType.I4)]int iWindowsMonNo ,[MarshalAs(UnmanagedType.I4)]int itype,[MarshalAs(UnmanagedType.LPStr)] StringBuilder cSerialNumber,[MarshalAs(UnmanagedType.I4)]int len);<br />
......<br />
<br />
fn call:<br />
int iControllerNumber = fnGetDiagnosticsData(iScreenNumber,iWindowsMonNo,itype,szSerialNumber,iLen);<br />
But I am getting Null Pointer exception during function call...Where am I going wrong?????

I'm not an expert in PInvoking things, but something that caught my eye was:
int* iWindowsMonNo -->> [MarshalAs(UnmanagedType.I4)]int iWindowsMonNo
You have a pointer to an int, but on the other side you pass an int value. I suspect that iWindowsMonNo is set to 0 because the API expects to fill it. use ref int
The same goes for the other pointer types.

Hello,
I have FormMain, which launches FormA and FormB. FormA launches a dialog box, and that dialog locks other windows. Meaning I can't access FormMain nor FormB. Is there a way of making it work in such a way that I can access FormMain and FormB, but not FormA?
Thank you.

If FormA is opening a modal dialog box it will block access to all the other dialogs in your app until it's closed. AFAIK there's no way to create a dialog that's modal to it's parent, but not it's grandparents or uncles.

From the .NET Windows Forms MSDN article "Displaying Modal and Modeless Windows Forms":
A modal form or dialog box must be closed or hidden before you can continue working with the rest of the application.
To do what you want, you need a hack that allows your dialog to show in a modeless state and, while it shows, prevent FormA from receiving focus; that is, when FormA gets focus, the dialog steals it. For example, put the following code in FormA:
private void FormA_Load(object sender, System.EventArgs e)
{
Dialog d = new Dialog();
this.Activated += new EventHandler( d.FormA_Activated );
d.Show();
}
and the following code in your dialog class which I've ostensibly named Dialog:
public void FormA_Activated( object sender, EventArgs e )
{
this.Focus();
}
This will let the dialog window steal the show from FormA while it is opened and allow you to play with the main form and FormB.

I'm looking for a faster way to determine AD inheritance. Example: User object "JDOE" is a member of security group "Test Group". "Test Group" is a member of "Test Group 2". The "JDOE" object does not show as being a member of "Test Group 2" exclusively, so a recursive search is the only way I've been able to figure it out. Problem with this is that it takes about 1 second per query -- if the user object belongs to a complex network of groups it takes a second for each group.
I a method that given the user object and group object, it will call itself for each group that its a member of recursively. In my case I belong to 14 groups, it had to query 23 group objects before it found "Test Group 2".
I may even be going about this the wrong way; perhaps AD is the wrong tool for the job. Any suggestions?

Hello Everyone,
I have decided to learn C# , having a good C++ backgroung , could you recommend me a good C# programming book for beginners.
PS. My favourite C++ programming book is C++ How to Program - Harvey M. Deitel

"Programming c#" from O'Reilly. It doesn't cover all the really advanced topics but ~98% of what I've needed to do in c# so far was cover. YMMV
I have the 4th ed which is .net2.0 most of it's contents are back applicable to 1.1 if you're required to work in the old environment.
Be careful with the title O'Reilly also has a book targeted at nonprogrammers with an extremely similar name.

I started with "Programming C#" from O'Reilly and it is a good book. But I picked up "Beginning Visual C#" from Wrox and I have to say that I prefer that one. I think it does a better job at explaining things. The first half is devoted to syntax using console application examples and the second half is devoted more towards the windows side of things using Windows application examples.

Hi, i have a project that uses a crystal report file. So i link this file to my access database and everythings is ok. But after creating the setup project and intalling it, the report is opening, there is no error, but there is no data in it. My guess is that here isn't anymore a connection with the database (because the setup changed the path or something). Does anone has any idea what this could be and how can i fix it? I'm trying to solve this problem for 2 weeks now and...no results so far.
Thanks!

Hi,
I am facing one problem while connecting my project to connecting with visual source safe(VSS).
actually it's problem of VSS
I am working with Visual studio 2005 beta 2 and my project database is on some another pc which is in LAN.Till date it's working fine without any problem but from yesterday i am getting problem, i don't reason.
Problem is that when i am tring to connect from my project to visual source safe database which is in another pc(in LAN),it directly ask me for visual source safe Internet database and asking for DNS and folder name in internet,actually which is not true becoz my actual vss database is in LAN.
I had reinstall vs 2005 beta 2 again but it is not solved.I am thinking that there must be some setting in vss administration to resolve this problem.
so any body is knowing solution about this type of problem?
if yes then pls. help me out.
thanks.
regards,

In exploring the VS2003 IDE, i tried out the Mark All feature in the replace dialog. How do you unmark code that gets marked?

So those markings are bookmarks. Now i know. Thanks for the tip.

Hi,
Last year I created a program that uses binary serialization for file saving. In the near future I'm planning on creating a new revision of this program, which will include many class structure changes from the current version. It seems that when using object serialization, adding and changing variables to current classes will cause errors during deserialization of older files. Are there ways to allow files created by older software versions to be compatible with newer ones? This is an area of programming I've never really explored. I'm unsure of common practices.
Thanks for any tips!

If you're using C# 2005 you can use the [OptionalFieldAttribute] on new class variables, and when you deserialize the class, the vars that have the above tag wont be required and therefore wont throw an exception.
If you're using C# 2003, you can look into manually controlling the serialization process.
BTW: M$ is giving away C#, VB, and C++ express for free until Nov. 2006.
If you get them before then, you will never have to pay for them. You can download CD images of each.
