Hi I have written an windows app with C# witch is supposed to syncronize 2 folders e.g
FROM: C:\Project\Project
TO: \\server\d$\my.project.com
I have made the entire source witch delete files/folders on TO and copy/create files if they don't exists.
My problem is when it tries to copy/delete files, I get permissions denied, I am running the program when I am logged in as administrator and I have administrations access on target machines.
I can open explorer and edit/delete the files witch it complains about.
What can I do to allow my app to copy/overwrite/delete files on the TO machine ?
Somehow as far as I can see, I can overwrite *.dll and *.pdb, but not *.aspx and *.cs
I have tried almost everything:
System.Security.Permissions.FileIOPermission
int token1;
WindowsIdentity mWI1 = WindowsIdentity.GetCurrent();
token1 = mWI1.Token.ToInt32();
IntPtr token2 = new IntPtr(token1);
ImpersonateLoggedOnUser(token2);
And many more, can it maybe be because the IIS is blocking those aspx files, in that case what can I do to overrule?
Because I have one similiar program with the name "InSync" with does overwrite the files when I run it with.

I'm attempting to retrieve an Active Directory attribute that is stored as as type OctetString. I want to convert this value to a string, but the Convert class doesn't seem to be able to do this. Can someone help?

Hmmm, ok I had to do a little searching here but if you read MSDN's page on ADS_OCTET_STRING[^] you will see that it is a struct containing a byte array. To convert this you might want to look into the BitConverter.ToString(..) method as it may handle this. You may also need to refer to the Marshal class under System.Runtime.InteropServices. Hope this helps.

.Net Bug:
Myself and 4 other developers using .Net (C#) in the development of new
software applications have the same problem with .Net. We are all working
on different products seperately and have all seen the same bug.
Bug:
The user develops user controls (UserControl) and stores them in a common project.
User adds this project to his main application project. User adds these
controls to his forms in his project. User goes a few weeks to months designing
his GUI. One day user opens his project to find controls and/or code
missing from his forms. The damn generated code just disappears along with
the controls on the form. This first happended to me 3 months ago and just
reappeared again.
I am one of these users. I use Source Safe, other people have used StarTeam
with the same results. Retrieving previously saved versions from SourceSafe
doesn't help because the .Net IDE has a mind of it's own and removes these
controls once again.
If anyone has any idea of what can be causing this or have experienced the
same, please let me know. This is my first post here so if this has been a
common topic before please excuse me.
Thanks,
TonyJ

Yes, that's known and easy to reproduce. To avoid it, read this[^].

.S.Rod.,
I am using fully qualified names for my controls. For example,
private [namespace name].ControlName m_Control
After I did this my code was actually stable for about 3
months and it just reappeared again last week. It reappeared
after the library failed to build. I fixed the library bug that
I introduced and now .Net has a mind of it's own. On my
simplest form I readded my controls, closed and saved them,
then reopened them to find the controls missing again.
.Net IDE even removed some event handling code.

Yes, I know. Make sure to use fully qualified using xxx; statement as well.

Hi,
I am using SDI window application in which I create multiple child windows.
I create child windows in this way
Form3 obj2 = new Form3();
obj2.TopLevel = false;
obj2.Parent = this;
obj2.Show();
But the child window's title bar always stays greyed out giving an impression that it is not in focus.
I do not want to go for MDI APP.
Could any one give any ideas on this
Thanks in Advance

The only way I know of is to override WndProc and handle the various commands related to WM_ACTIVATE and WM_ACTIVATEAPP. If you haven't done it before, a search here and on Google might help you find someone who has implemented it in .NET. (I know there is one, I just can't remember where.)

Hi all,
I keep getting a casting exception in the following section of code. I can't seem to convert from the object to int.
Also,
is there any way of getting the first element from queryCollection other than having to enmerate through it?
Thanks for yeer help,
J.
[code]
ManagementObjectCollection queryCollection = query.Get();
int tempint;
Object obj;
foreach(ManagementObject mo in queryCollection)
{
obj = mo.InvokeMethod("Terminate", null);
Exception here------>tempint = (int) obj;
return tempint;
}
[/code]

Don't know if this is the problem, but you can't cast an int from an object unless the object is an int. I've no idea what Terminate returns, so it's impossible to say whether it is an int in these terms.
You might want to try tempint = Convert.ToInt32(obj); instead of direct casting.

What does the C# command this.BeginInvoke(new CaptureDone(this.OnCaptureDone));? And what's this in C++? Is it a message (like a windows message WM_???) or is it a callback funktion, that will be called?

It is similar to a callback function; except that BeginInvoke will call the method from a different thread.

Invoke and BeginInvoke are related. They are directly related to threading. If "this" is a System.Windows.Control or a descendant, then they also have a correspondence with windows messages.
BeginInvoke just triggers the activity and keeps on moving.
Invoke waits until the activity is finished before continuing.
Example 1:
Thread 1 creates a Form with a list view.
Thread 2 wants to change the content of the list.
Thread 2 calls Form.BeginInvoke(...).
Thread 2 keeps on doing stuff while Thread 1 does the work.
Example 2:
Thread 1 creates a Form with a list view.
Thread 2 wants to change the content of the list.
Thread 2 calls Form.Invoke(...).
Thread 2 waits until Thread 1 finishes the work.
Thread 2 continues.
It is easy to see that for list view changes, this is posting messages and either waiting or not waiting for a response. The message thing also relates to the idea that only the Creating thread should make changes to the window.
If you were talking about generic BeginInvoke and Invoke for use with Delegates, then the message relation is thrown out and we're talking solely about callbacks.

Greetings!
I found myself trying to create an add-in in Vs.net using C# but was not quite sure where to start. I have searched the site and several others including the msdn.microsoft.com site for information in regards to this.
If anyone has any information/tutorials/point in the right direction type assistance please inform!
My end goal is to create an add-in for outlook..
Thanks!

I have no experience in writing Outlook add-ins but something like this might be of interest...

Are there anything like C++ "%s" or "%f" in C#? Essentially if you have a big query and you have 10 placeholders, what is the cleanest way of filling it up...for instance, in MFC you could do ,
LPCSTR lpQuery = "EXEC MySP %s, %s,%s";
CString szQuery;
szQuery.Format("a", "b", "c");
which is clean and simple....how would you do something like this in c#?
|

You can do a similar thing in C# with the String.Format() method.
See:
http://search.microsoft.com/gomsuri.asp?n=3&c=rp_Results&
siteid=us/dev&target=http://msdn.microsoft.com/library/en-us/
cpref/html/frlrfSystemStringClassFormatTopic.asp
The long and short of it is this:
sQuery = String.Format("EXEC MySP {0}", sSPVariable);

This kind of code can lead to some bugs and security issues. If you want to keep with it or for uses other than SQL queries, use String.Format(), or, for better performance and solve the bugs I've mentioned, use classes like SqlCommand and SqlParameter.
