I've been looking at the platform SDK, and what I have at the moment in terms of code. I think it was actualy solved a while ago, it just didn't match what the documentation states.
FOr some reason, the zero value of the STRRET that is returned from my method appears to be correct and functioning.
The string returns a full path if I set the NORMAL flag, with a square charachter on the end, and simply a square charachter if I set the INFOLDER.
The problem I have is, if I am getting the object name, where is the square charachter comming from? How does the full path that is returned get generated? The square value would be where the name of the object should be, say a file or something. The odd thing is, it appears to not realise it's actualy looking for a folder.
Normal Flag:
@"C:\Documents and Settings\All Users\Desktop\?"
INFOLDER Flag:
@"?"
where the question mark is the square charachter.
Any ideas why this is the case? And why I can't seem to get the folder value returned?
Cheers

This little sqaure character is most likely the string termination character, ASCII value 0.
It is VERY common throught the Win32 API to pass strings with a null termination character, ASCII 0.

So if I correctly understand the post an SDK function is called which returns a STRRET that ends with a "square" character instead of an expected "question mark."
Research into [C# Spec Escape Sequences] reveals "\?" is most likely not a valid escape sequence for a "square" character.
Additionally, the @"" preceeding the string means to treat the string verbatim, i.e. to not process escape sequences.
Have you tried to remove the verbatim @"" and use escape sequences, i.e. each \ in the call string becomes \\ ?
What SDK function are you calling? Can you post a code example?
Sincerely,
-Ron

Hi Guys
I need your help. (please...) I don't know if my question is on the correct newsgroup.
I created a C# program that listen to another computer get the data and save it to SQL server databse using his port number. I need to run this program into the windows service so that it will run continously.
I don't want to use the windows scheduler. I want to create a C# program that will function as service and run my program at the same time.
Please any help or tutorials would of great help tome.
thanks in advance, specially the time.

I've been using the AxWebBrowser control for some time now. Lately though, it's been giving me this error message when I exit the program (after debugging).
<br />
An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in system.windows.forms.dll<br />
<br />
Additional information: Unable to get the window handle for the 'AxWebBrowser' control. Windowless ActiveX controls are not supported.<br />

There is nothing native in the .NET Framework to modify the Access Control Lists on Files, as far as I can find. You would have to use calls into the API to accomplish this. It would require writing up a couple dozen structure and function headers:
LookupAccountName, InitializeSecurityDescriptor, GetSecurityDescriptorDacl, GetFileSecurityN, GetFileSecurity, GetAclInformation, EqualSid, GetLengthSid, InitializeAcl, GetAce, AddAce, AddAccessAllowedAce, AddAccessDeniedAce, SetSecurityDescriptorDacl, SetFileSecurity, ...
then there's the structures that go along with them:
SECURITY_DESCRIPTOR, ACL_SIZE_INFORMATION, ACL, ACCESS_ALLOWED_ACE, ACCESS_DENIED_ACE, ACE_HEADER

public void PaintObject()
{
if (DESIGNTIME == true) DrawRectArountControl();

}

Sure, try using base.DesignMode().

What the problem really is, is that I wanted to store a function inside a namespace instead of a class, but that appearantly cannot be done. I have several very different classes witch all must use one function. I feel it would be waste of memory if I just drop the function to each class, or create an seperate class called something like MyFunctionsStoreClass that would store all the functions I might need. Is there an alternative ?

Yes, methods need to be inside a class. If you don't need an instance, you can add the word 'static' before the function declaration (like in 'static void blablabla()') and use it by calling ClassName.blablabla(), without the need for an instance.

In C#, yes. In IL, you can have global functions. I just include this for posterity. You're right about C#.
