- Dotnet >> Intelli-Sense How do I FIX???Anyone here having problems with intellesense just stopping?
Sometimes after compiling and running a program when I go back to the editor
and start typing all of my syntax highlighting dissapears. All of my text
goes black like a regular text document. If I rebuild the project or
projects the syntax highlighting shows up again.
Also when the text goes black all of my intelli-sense quits working as well
or only shows main methods and does not drill down to the specific methods
it should.
If I continue to program I have to type everything without intellesense and
when I do this no syntax formatting happens including brace placement etc.
Also when it is acting like this if I were to make a mistake and try doing
an undo I get an error and nothing is undone. It is like visual studio
totally loses track of everything.
Another thing I have noticed is that some of my project dates do not update
either. When I first go into visual studio it shows the projects and when
they were last updated. Some of the projects do not update the date of
when they were last worked on even though I work on them quite a bit.
In order to solve the problem temporarly I have to exit out of visual studio
and reload the project. Help this is getting very very anoying!!!!

- Net Framework >> Telling where we are in the stackHi All,
I'm trying to use this to determine which method called my method. I
have two ways, but neither is quite right:
Method 1:
Sub WhereAreWe()
Dim sf As New System.Diagnostics.StackFrame(1, True)
...
End Sub
But in this code
1 Sub Test()
2 WhereAreWe()
3 WhereAreWe()
4 End Sub
the stack frame is different in each WhereAreWe call, in that the first
time it knows that the caller is on line 2 and the second it knows that
it's on line 3. I can get around this by using StackFrame.GetMethod,
but then I get a different problem:
Method 2:
1 Sub RecursionTest()
2 If ReachedBottom Then Exit Sub
3
4 WhereAreWe()
5 RecursionTest()
6 End Sub
When I do this, the WhereAreWe function has no way of telling where,
exactly, we are, because GetMethod is the same for regardless of how
many frames deep we are in the recursive call stack.
So, is there any way to tell where we are, solving both of these
problems at once? TIA.
Cheers,
Josh

- Visual C#.Net >> Installing a font using C#Hi
I was wondering if anyone knows how to install a system font using C#?
I know it doesn´t do the trick to simply copy the font to the font
directory, it just doesn´t become active.
Any ideas?

- Microsoft Project >> Dragging Finish DateIn a Gantt view of my project (MSP2000), when I try to drag the Finish
date of a task, the whole task moves instead of increasing the
Duration. This happens for any task I try to change.
If I create a new task, it behaves the same until I set the Constraint
Type to As Soon As Possible. The task Start date automatically
changes to the Project Start date. Only then I can drag the finish
date to extend the duration.
In a new project file, I can drag the Finish Date as per design.
Help?

- Dotnet >> Process CPU usage jumps to 100% without any reason?I am working on an application in c# that runs in the background.
All it does is monitor a value from a performance counter using a timer. It then draws these values in a chart
Now, this application works for a long time, sometimes even days. But sometimes it just freezes and the CPU usag
spikes to 100% for that process. I really don't understand why, and there seems to be no actual event that trigger
this. It looks like this problem occures more when I am using more CPU power during a long period of tim
(f.e. when compressing something). But even then, sometimes the program freezes and sometimes it keeps running
smooth at 0-2% usage..
Is there anyone that can give me an idea on how to solve this problem
I thank you for your time
Kind regards

Net Framework >> .Net Framework 1.1 SP1 brok COM+ components
After installing SP1 for the .Net framework 1.1 on a Windows 2000 server, all
the COM+ components ceased to be accessible from my VB6 applications. The
only error that was received was that it could not load the dll. I ended up
deleting the components and reapplying them with regsvcs.
Fortunately, we only have a few .Net COM+ components being accessed by VB6.
Has anyone else seen this?

- Dotnet >> Logging Into a ServerHello All,
I'm hoping someone can point me in the right direction. This is outside of
my experience with VB. I have an application (written in VB.NET) that
allows a user to enter a part of the file name and all file matches in a
specific
directory are copied to the user's desktop. It's a simple but useful tool.
Now an outside company requires access to the data. The files have been
moved to a Windows 2000 server accessible via the internet (i.e. outside the
firewall) so the other company can access the files. Both companies are
going to use this program. Since this server is not on our (or any) domain
I must log into that server. Therein lies my question. How do I
programmatically supply a user name and password to the server? We do not
want the other company to know the user name and password to the server.
The "best" solution is a web application, but I need to get this working
immediately and I haven't much experience with ASP.
Thank you for your help.

3. Enter url to proxy script or info for proxy server in respective text box
4. Press test-button
---------------My Code is -------------------------------------------------
DateTime dt1 = DateTime.Now;
System.Net.HttpWebRequest myReq =
(HttpWebRequest)WebRequest.Create(tbxURL.Text.ToString());
//GetResponse for this request.
HttpWebResponse response = (HttpWebResponse)myReq.GetResponse();
DateTime dt2 = DateTime.Now;
lblTimeTaken.Text = Convert.ToString(dt2.Subtract(dt1));
--------------------------------------------------------------------
in this code , i m unable to set the value of proxy script textbox ,if any
or proxy server(Address and port) ,only thing which i do threough this code
is sending the url without any proxyscript ans proxy server(address and port
info) Can anybody tell me how can i do this thorugh the code....

- Net Framework >> Is this s bug?Hi All
I have one query, and need urgent help here. It is related with Windows
Address
Book(WAB). Suppose I open a link to WAB through my application's (developed
in VC++) dialog box. Now, if I get the focus back on my dialog box with the
WAB still opened(not in focus though), I cannot navigate through the
controls in my dialog box through the TAB key. Also, ENTER key does not
work. But the dialog box starts responding to the TAB and ENTER keys as soon
as WAB is closed. Why is it happening like this. I had downloaded a sample
WAB program from www.microsoft.com and this program too had the same
problem. I want to know if it is a bug or a normal behavior in VC++ and WAB
integration. Is there any workaround to this problem.
Thanks for your time.
Regards,
AA

- Microsoft Project >> error: valid product key must be set to create an admin imageI'm trying to set up an administrative installation point for project 2002
professional including MUI-packs (german; maybe french, too). When installing
the MUI-Pack to the administrative share using the usual command
"<cdrom>:\1031\setup /a"
the setup stops after completing all dialogs (accept, installation path)with
installer error
"A valid Product Key must be set to create an Admin image"
I was never asked for a licensing key and IMHO the MUI kits don't handle
licensing, anyway. I'm using Project 2002 pro with volume licensing key and
the MUI CD2 from MSDN Subscriber Downloads. Poject 2002 us-english
kernel runs without problems.
It's independent of the installation path I choose.
Ideas?

Here's the code....
The line where the error occurs is in Bold Blue
Any ideas appreciated!! ;-)

- Net Framework >> Get LOGON USER name in .NET 2.0I recentlly converted some web services to 2.0. So far everything has worked
great with the exception of one of the functions in an AD service.
the following code:
string sUser = HttpContext.Current.Request.ServerVariables["LOGON_USER"];
Worksk fine if debugging in VS 2005 but when I publish to the server. An
empty string is returned. I have tried to catch an error and does not appear
to be one.

- ADO >> DataTable LimitationsI've found a MSDN reference to the fact that an ADO.NET DataTable is limited
to 16,777,216 rows of data [1], but what I cannot find is a reference for
the maximum columns per DataTable, maximum bytes per DataRow, etc. Is this
information documented anywhere?
TIA!

- Visual C#.Net >> Creating a dynamic array...Hello.
I have figured out how to create an instance of an object only knowing the
type by string.
string sName = "MyClassName";
Type t = Type.GetType(sName);
Object objNew = Activator.CreateInstance(t);
This works, but now I need to declare an array like
Object[] objNew = Activator.CreateInstance(t)[0];
This doesn't work. Can anyone help?
Thanks.

- Dotnet >> Dynamically creating a Word documentI want to create a Word document that will display data from a database. I
don't want to create the file on the server, I just want to stream it out
directly to the user. When they click a button, the Word Save Open window
will open, and allow the user to Save or Open the document in Word. I know I
need to use response.binarywrite, but I don't know if it is possible to
create the binary object without first saving it to a temporary file. Would
I need to create a Word template, and how would I use it?
How would I get data from a data grid into this document?

- Visual C#.Net >> Postfix incrementHello!
I have found an interesting thing with postfix operator ++.
What should contain the variable i after exceution the following code:
int i = 5;
i = i++;
In VC++ 7.1 and VC++ 2005 beta 2 the variable i contains 6.
But in C# 7.1 and C# 2005 beta 2 the variable i contains 5.
Is it behaviour correct? Can anyone explain what is the correct result?
Best regards,
Oleg.
