I have just added help to my C# application, and it invokes the Help window when F1 is pressed just as it should. However, I find that the help window itself disappears or is covered by my app (the app is always maximized) whenever the app loses focus. For reasons I won't go into at the moment, my app creates additional windows that it arranges for itself, but I don't know if this has any bearing on the matter. All I can say for sure is that if my app loses the focus, the Help window disappears. It comes back if I click on the title bar of my app to get focus back, but if I click on the title bar of the Help window, my app loses focus, and the help window goes away again!
Does anyone know of a setting I may have made in my app that would cause this behavior?

Just try this code and tell me , whether it served your purpose or not.
System.Diagnostics.Process.Start(@"c:\\help.chm");
and don't forget to refer System.Configuration namespace in your code.;)

That worked just fine. Thanks! Is there any way I can access individual topics this way for context-sensitive help?

You can achive it throught some third party help creator tool Or you can use Microsoft Help Workshop. This you will get through .NET installation.;)

I am looking for a sample of code in C# using as a web service which would do the following:
1. Accept a XML stream
2. Parse the XML, prep for inserting into a database table
3. Set a Session ID
4. Return the Session ID to the Requester.
If someone could show me how this is done, I would be most appreciative.
Cheers,
Shelly

Thanks

Sure, the sqlite.dll that you're P/Invoking into couldn't be loaded. The message is not refering to your assembly, but the dll that your assembly is trying to call into. You probably need to put the sqlite.dll into you bin\debug or bin\release directory.

Would you know how I may add controls that aligns itself to the right of the menu bar (MenuStrip) in whidbey.
Office 2003 has a similar feature. On the menu bar of Word 2003 there is a "type a question for help" combobox which is aligned to the right. I need to mimic this behavior.
Kindly help. Thanks

When the form is resized, the right aligned ToolStripItems are layed over the menu items. Is there any way to change that behavior?
Say like, truncating them or automatically making it go into a drop down button list. Or programmaticaly can we identify the sizes and locations to make them invisible?

Ok, i got a program, and when you start it you get the option to either, enable / disable the password, but thats all. Theres no actual file to protect, now i could put the file into the program BEFORE compiling it, but then how would you get a new file in there?
So is there a way i can run the program, then add a file to it.
The main idea is to protect a file with a password so that when you click on the file it asks for a password, you enter the password and then the file is back to normal.
Any ideas

First, it's already been done - it's called a WinZip Self Extracting Executable.
In order to use the files, you actually have to unpack them first. Once that is done, you don't need any password to use them, so what's the point?
The method that you describe only protects the files during transport from machine to machine. It can't do anything about the files once they're unpacked. Also, unless the files are encrypted in the self-extractor package, it's not that hard to pull the files out of the package without the password.
Also, the files are not compiled into the .EXE as you put it. Rather, the file package (or .ZIP in our example), encrypted or not, is appended to the end of the .EXE file. The .EXE has to know how far into the file to start looking for the .file package, then it's a simple process of processing the files from there.
The file format could look something like this:
[SelfExtractor code][FilePackagePre-Amble][FilePackage][possiblePost-Amble and ErrorCheckID]

I am currently making a user control that contains a collection of my custom control witch overides OnPaint method. I use:
My custom control constructor inits those style:
SetStyle(System.Windows.Forms.ControlStyles.DoubleBuffer, true);
SetStyle(System.Windows.Forms.ControlStyles.AllPaintingInWmPaint, true);
SetStyle(System.Windows.Forms.ControlStyles.ResizeRedraw, true);
SetStyle(System.Windows.Forms.ControlStyles.UserPaint, true);
UpdateStyles();
Now, my user control constructor add a collection of my custom control
to its Controls Collection and also sets ControlStyles like my custom control does.
My user control overrides OnLayout to place the collection of custom control as a special way. I SuspendLayout at the Begining of OnLayout and ResumeLayout at the end. So my problem is that my user control OnPaint event is not called so DoubleBuffering is not working on user control.
Is it because I use double buffering in my custom control or is just
a desing problem? If someone could help me with that, I will apreciate a lot. And I am sorry for my english, if its'no clear just please tell me.

However try as i might (and i am trying  )i cannot get them to link programatically, or even know if it can be done. I am not looking for help on validation, as i know how this works using XmlValidatingReader etc.

This message goes out to all the regular expression gurus out there:
I have a very simple regular expression declaration:
regex.Regex ex = new System.Text.RegularExpressions.Regex("\\(");
I want to know how to test against this regular expression so that if the tested string does not match EXACTLY then its going to give me false. For example:-
string test = "a(";
regex.Regex ex = new System.Text.RegularExpressions.Regex("\\(");
System.Console.WriteLine(ex.IsMatch(test, 0));
should return false (which it does not). How do I do this?
Secondly, I want to recursively define a definition but I do non know exactly how. I have an expression and it COULD be enclosed in brackets. So lets say I have the following:
E -> (E)
I could alse have:
E -> C-E
C -> constant
How do I write a definition like this? I'm very much not keen on writing a parser, I assure you!
Thanks a lot!
Jim

I'm not familiar with the .net regex syntax, just the Perl syntax, but in Perl you can write ^\($ where ^ means "beginning of the string" and $ means "end of the string". Hopefully there are equivalents in .net that you can use.

Thanks, does anyone know how to step around the recursion problem?

AFAIK, there is no way you can implement reductions like the ones you posted using regular expressions. That's the job of parsers.

They said that these regular expressions were built on NFAs... Such a regular expression would be possible with an NFA, no?
Is there a built in parser anywhere?

Hello all,
I have an application that attempts to send emails via an exchange server on another machine. The code I am using is as follows :
MailMessage aMessage = new MailMessage();
aMessage.From = "johndoe@server.com";
aMessage.To = "janedoe@server.com";
aMessage.Subject = "Test Subject";
aMessage.Body = "Test Body";
System.Threading.Thread.Sleep(3000);
MailAttachment mat = new MailAttachment("c:\path\to\attachment\att.jpg")
aMessage.Attachments.Add(mat);
SmtpMail.SmtpServer.Insert(0, "SERVER IP ADDRESS");
SmtpMail.Send(aMessage);
60% of the time this code works, but on occasions I get the following exception thrown by the .Send
System.Runtime.InteropServices.COMException (0x80040220): The "SendUsing" configuration value is invalid.
After hunting around google for a while I am none the wiser as to a solution to this problem. Although I have made some code tweaks to match certain suggestions
Does anybody have any suggestions
post.mode = postmodes.signature;
SELECT everything FROM everywhere WHERE something = something_else;
> 1 Row Returned
> 42

There is an MS knowledgebase article regarding this exception here.[^]
Does that help at all?

Hi,
I am passing an object of a class declared in my C# code to an unmanaged VC++ dll.
If my class contains an int/double/char and may be some functions then I can get their values in the dll. Also I can modify the values there and the modified values I can get in my C# code. So it works fine.
But if I include a string in my class then I can get the values of other variables except the string. And if I modify ANY value in the dll then it does not get reflected in my C# code.
I am unable to proceed. plz help me...

 Hi guys, I have a question... I have managed to program a simple game, but I need help in creating a starting menu. For example, the options would be, "start", "high score" "help" "exit".
I hope anyone with game programming can help me out soon. Thanks in advance!!!

some more details would be nice.
How have you made the game, using GDI+, directX openGL?
If you've used GDI+ just use windwos forms buttons for your options.
Otherwise give a bit more info.
Cheers
Kev
