Need tab and Return key for IE Hosted UserControl
I am writting an IE Hosted UserControl, which has a TextBox for accept
input. In the textbox, I use OnKeyDown handler to check the user pressed
key. Which work fine under WinForm environment.
However, under IE with form environment, the Key tab and return are took by
IE.
How can I get the Key tab and return in textbox under IE environment?
Thanks.

About IE Hosted UserControl auto download
I have just finished an IE Hosted UserControl named MyUserControl, which can
automatically download from IIS site if I assigned the URL to
http://MyComputer/MyFolder/index.htm. However, if I assigned the URL to
http://www.MyCompany.com/MyFolder/index.htm or
http://localhost/MyFolder/index.htm, IE will not automatically download the
MyUserControl from iis. Where three of MyComputer, www.MyCompany.com, and
localhost means same machine.
Why? They are same machine, why only a shortly computer name can download,
but long site name and localhost cannot download? Because of security
issue?
Thanks.

Calling WebService from Windows App causes Windows App to never qu
I created a WebService on the order of a WindowsUpdate type of functionality.
I call the following routine, and once I've done that, my Windows
Application stays around as a running process forever (or until I kill it
with task manager). This is very odd. The application does not appear to
hang, it seems to work perfectly. It even appears to exit, but looking in
task manager you can see that it stays in memory. There must be something I
have to do to properly dispose of my web service, but I'm not sure what it
is. Can anyone help? (Yes, I call the dispose method, but that doesn't
appear to do anything).

C#2.0 Form to COM object?
I have a standalone app created in C# that is used to browse a database
of archived documents called DocDB.
We have some older legacy code written in Delphi that we wish to
enhance with the DocDB's functionality.
My idea was to give DocDB methods for controlling it from a seperate
process via COM (much like Word for example, but with only a few public
methods)
I have defined public methods in my forms based class, I have used an
SNK file, I successfully installed it into the GAC and run regasm. I
have also created a public interface for the few methods I need.
But no matter what I have done, the TLB that I create never exposes the
public methods when imported into my legacy app.
The code looks something like this (using C# 2.0):
namespace DocsDB
{
[Guid("3100EBCE-1E40-500b-A247=AD-C777D72BB2ED")]
public interface IDocsDBUI
{
void ViewDocsForLoan(int loan);
void IsVisible(bool visible);
void Quit();
}
[Guid("AA218A41-ED34-5f4e-95C1=AD-0F1DB0402AD9")]
[ProgId("DocsDB.App")]
[ClassInterface(ClassInterface=ADType.AutoDual)]
public partial class frmMain : Form, IDocsDBUI
{
public frmMain()
{
InitializeComponent();
}
public void IsVisible(bool visible)
{
this.Visible =3D visible;
}
public void Quit()
{
this.Close();
}
public void ViewDocsForLoan(int loan)
{
// do something here
}
}
}
Can someone tell me what I might be doing wrong? A small working
example would be very much appreciated. Tag: System.Net.Sockets.Socket Memory Leak Tag: 96227

when is hashcode used?
Hello All,
I have been facing this bizarre problem within a combobox having a list of
UK postcodes. When I assign the SelectedItem propoerty of the combobox, a
completely different item was actually selected in the combobox. I broke
into the code at the assignment statement and then looked at the values for
different items in the watch window. It looked something like this :
postcodeObj : EH11 1LQ
comboBox1.SelectedIndex = -1 (nothing currently selected)
comboBox1.Items.IndexOf(postcodeObj) : 1614
comboBox1.Items[1614].ToString() : EH11 1LA (something different to what i
am intending to set as selected item)
I also found out that my item was at the location 1621 in the combobox
items.
The combobox is no sorted, and I couldn't figure out what was going wrong
here, till I added 2 more things in the watch window
comboBox1.Items[1614].GetHashCode( )
comboBox1.Items[1621].GetHashCode( )
These 2 values appeared to be same, Now I remember that I have overriden the
GetHashCode() method in my postcode object to return a hashcode, it creates
a hashcode based on the postcode string and one more attribute. (XOR the
number and the hashcode of the string)
My question is, Is hashcode used internally by the 'SelectedItem' set
method? Is there any way for me to get round this problem? I have the
postcode strings and a unique number, Can I generate a unique hashcode from
this combination? I don't want the number to be my hashcode.
TIA,

Reflection: accessing member of given object
Hi, I have trouble finding info on the following:
I have an object myDataAccessObject that contains heaps of SQLDataAdapters
and derivatives thereof. These are auto-generated for me by VS.
I want to be able to call the update-method on all of these (in effect doing
a database-dump) with myDataSet as input (since that's where my data is).
now I *could* put all the adapters into a list and loop through them,
calling the update method, but that's not pretty and I will have to manage
that list as the DB expands so I don't want to do that.
basicly I want to:
-get all sqladapters from myObject
-call "Update" with parameter myDataSet on all of them
that shouldn't be so hard, yet I am stuck and am finding no docs on it.

Implications of using typeFilterLevel=Full after strong naming assemblies
Hi,
Env: Windows 2003, VS 2003, .Net 1.1
We just started strong naming our assemblies and ran into a .Net Security
Exception when remoting between ASP.Net and our Windows service. The
remoting call that failed with this exception returns an array of DataRows
(from a strongly typed DataSet) from the service to ASP.Net. All our
assemblies (apart from Microsft.Security.SSPI sink) are private.
The exception is:
Security Exception
Description: The application attempted to perform an operation not allowed
by the security policy. To grant this application the required permission
please contact your system administrator or change the application's trust
level in the configuration file.
Exception Details: System.Security.SecurityException: Request failed.
Source Error:
An unhandled exception was generated during the execution of the
current web request. Information regarding the origin and location of the
exception can be identified using the exception stack trace below.
Stack Trace:
[SecurityException: Request failed.]
Anyway, we solved this by setting the 'typeFilterLevel' to 'Full' in our
server config file:
<formatter ref="binary" typeFilterLevel="Full" />
After some research I found that people have mentioned security and possible
performance issues with setting this level to 'Full', so I've a few
questions on the implications of opening this up:
1) Why does strong naming a private assembly cause this problem, when an
unnamed private assembly works fine?
2) I doubt it, but are there any performance issues?
3) The security issues appear to be from spoofing and code injection:
http://blogs.msdn.com/manishg/archive/2004/10/27/248841.aspx
Can you please confirm that these security issues existed before we strong
named our assemblies and had to set the typeFilterLevel to full?
This doesn't mean we'll ignore the vulnerabilities (we already authenticate
callers), but we're just trying to understand the impact of this change.
Thanks very much,
Stuart

InvokeRequired and CreateGraphics
Hi,
Here is what the documentation of InvokeRequired says :
"In addition to the InvokeRequired property, there are four methods on a
control that are safe to call from any thread: Invoke, BeginInvoke,
EndInvoke and CreateGraphics. For all other method calls, you should use one
of these invoke methods when calling from a different thread. "
Could someone explain me why a call to CreateGraphics is "safe" ? One of my
backgroud threads calls CreateGraphics on a control but when this control is
destroyed (ie the application is closed), this thread is blocked on the call
to CreateGraphics and isn't aborted. I don't understand why a call to Invoke
isn't required in this case.

Saving the state of UI
Hi,
User can adjust the size of columns of a table or the position of splitter
in UI. We want these adjustments to be remembered when we restart the
application. Currently, we are saving these adjustments by the user in an
XML and saving that XML. We read the XML upon restart and make calls to set
the adjustments. This approach becomes difficult as we add more controls and
more settings can be made by the user. What other techniques can be use to
save (perhaps automatically) the STATE OF UI? As in Java, can we use
Serialization of UI to save its state [Java's Swings control are
serializable while in .Net, Form and all the controls are not serializable]?
Any pointers to articles on various approaches to SAVING THE STATE OF THE
ADJUSTMENTS made by the user will be greatly appreciated.

Socket and multi-threading
Hi,
Socket class documentation says that it is not thread safe. We understand
that if do simultaneous sends on ONE socket then it will be a problem (or
simultaneous receive). Can we create TWO threads on OUR OWN such that one
will do SEND and one will do RECEIVE using the SAME socket reference? This
means that two threads WILL BE in the same SOCKET object - one doing receive
and one doing send. We know we can use asynchronous calls on the socket to
achieve this but whether we can do this using our own threads. Any pointers
to official documentation that shows that this is permissible?

Simple string encryption (solution)
This message includes a solution for encrypting and encoding a string
into a "safe" character string that you can read or pass in ASP.NET
querystrings, and then decode and decrypt it back to its original form.
If you find it useful, please let me know.
I had an issue with a web site that I was working on where I needed to
pass around a moniker in my querystring. While the database itself
performed relevant security checks, I didn't want to expose this to my
users. The problem I had is that I just wanted to encrypt/decrypt a
string without having to know or understand anything about the
cryptography namespace. I also wanted to be able to pass this value
around in my QueryString. This code takes the unmodified symmetric
encryption example code that Lion Shi posted a while back on Usenet,
converts the resultant bytes to hex and then performs a simple
substitution for aesthetics.
If you plan to use this for your own purposes, and since I've posted
this publicly, I recommend you change the values of the two variables
having the value of "password" (they don't have to match, but if I
remember what I've read on DES, I believe they need to be a multiple of
8 characters in length).
The code that Lion Shi originally posted is located here:
http://groups-beta.google.com/group/microsoft.public.dotnet.languages.csharp/msg/eb7712e9e5cc1045?hl=en
This is the modified version that encodes the resultant byte arrays
into strings. It seems to work on the three strings that I've tested it
with, but I make no guarantees on its security or reliability.
Usage Example:
string s = "Raw Text String";
Response.Write(s);
s = Encryption.Encode(s);
Response.Write(s);
s = Encryption.Decode(s);
Response.Write(s);

Automate screen scraping: How to programmically "push" a Login button on another web page?
I'm hoping to write a utility program that will navigate to another web

on a schedule.
When I use HttpWebRequest to get the initial logon screen, there are
multiple embedded forms (Login, Forgot your Password, etc).
I want to be able to pass my username/password information to the web
page's login form and "push" the button (on their webpage, this is done
through some javascript code). When I view the source code of this
page, it appears that several hidden variables are set, so I imagine
the I would need to get/accept/return cookies.
I'm not sure how to "direct" the infomration to a page's particular
"form" - in my case, "pushing" the Login button.
Is there an example to automating this type of login that someone could
share with me?

I mean the mycombo look like a real combobox. However, the MyCombo.form

control. When user click on another application to make the mainform which
mycombo belong to deactive, the mycombo.textbox disappear with the mainform,
but the mycombo.form just hang up there. Another example is, if the user
drag the mainform to move from location A to location B, mycombo.textbox
move together, but mycombo.form doesn't.

mycombo.textbox. Form control is the topest level control which cann't

Adding literals to an existing Enum at runtime
I have seen an example of how to create a new Enum at runtime using
EnumBuilder.

displaying country name in current UI culture?
I have a two-letter country code and I need to display the name of this
country in the current UI culture.
Sadly I can't create a CultureInfo and use the DisplayName property
because this displays it in the localised version of the .NET framework
and not in the current UI culture which I might have changed (it is
calculated regardless of the language that the system is set to
display).
e.g:
country code: US
current ui culture: Spanish:
test string i need: "Estados Unidos"
Any suggestions? Tag: System.Net.Sockets.Socket Memory Leak Tag: 96103
Redistributing DIA dll problems
Hi All
I'm trying to distribute msdia80.dll (Debug Interface Access SDK) with my
application. The problem is that regsvr32 generates the following error when
I try and register the dll on the installation machine.
"LoadLibrary ( "msdia80.dll" ) failed - This application has failed to start
because the application configuration is incorrect. Reinstalling the
application may fix this problem."
I have installed the .NET Framework Version 2 Redistributable Package on the
installation machine as msdia80.dll has a dependency on msvcr80.dll. As far
as I'm aware this should be all I need to do but obviously not. Can anyone
help?
Thanks in advance Tag: System.Net.Sockets.Socket Memory Leak Tag: 96102
Problem faced while creating setup file for Pocket PC application
I Created a Pocket PC application for iPAQ 5450. Every thing went fine even
installer creation. I could run the setup and install it into the actual
device and worked fine. The application enables syncronization with remote
database using merge replication.
I found contradictory results while installing the application. I will
mention here all the steps that I done while creating and installing setups.
Result: Case 1: worked fine. Case 2: show problem.
Case 1:
---------
Developing and installation site Details
-------------------------------------------
Operating System
1. Windows 2000 server
2. Windows XP with SP2
Development Environment
1. Microsoft .NET 2003
2. Framework 1.1 with SP1
Backend
1. SQL Server 2000 Standard Edition
2. SQL CE 2.0
Communication Tool with Pocket PC
1. Microsoft Active Sync 3.8
Steps followed to create the Setup file
1. Created cab file for my application.
2. Included the cab file names in the INI file to install the cab file
corresponding to the Pocket PC processor.
3. Created another INI file to include the names of the .NET Compact
Framework cab(netcf.core.ppc3.x86.cab,
netcf.core.ppc3.x86.cab,
netcf.core.ppc3.x86.cab, netcf.core.ppc3.x86.cab) files to
install .net
compact framework corresponding to the Pocket PC processor.
4. Created another INI file to include the names of the SQL CE cab
(sqlce.ppc3.mips.cab, sqlce.ppc3.sh3.cab, sqlce.ppc3.x86.cab,
sqlce.ppc3.ARM.cab) files to install sql ce corresponding to
the Pocket
PC processor.
5. Created an Installer project to run CEAPPMGR while installing and
uninstalling.
6. Created dll file from the Installer project.
7. Included new setup project to the solution.
8. Added Installer dll to the setup project.
9. Referred that dll in the install and uninstall process of custom action.
10. Added three INI files to our setup application to install .NET Compact
Framework, SQL CE and my application.
11. Included all cab files to the setup project, which includes .NET Compact
Framework, SQL CE and my application.
12. Build the Setup file.
By doing so, setup installed everything (.NET Compact Framework, SQL CE and
my application). I have tested this many times in my Pocket PC. Every time it
installed successfully.
Case 2.
---------
Developing and installation site Details
-------------------------------------------
Operating System
1. Windows 2003 server
2. Windows XP with SP2
Development Environment
1. Microsoft .NET 2003
2. Framework 1.1 with SP1
Backend
1. SQL Server 2000 Enterprise Edition
2. SQL CE 2.0
Communication Tool with Pocket PC
1. Microsoft Active Sync 3.8
Steps followed to create the Setup file
I have followed all the steps in the Case 1
But in this case I failed to install the application to the Pocket PC along
with Sql CE Cab and netcf cab. In 2003 server it is showing CEAPPMGR.EXE
Application error. In Windows XP it is showing â??Send error reportâ??. Error
produced in windows XP is in fact a contradictory one from CASE 1.
But I tried with separate installation for each cab file. At that time it is
working fine. But while installing along with any one of supporting cab files
it shows error message. I tried this in different machines, but same error is
throwing. I tried again in Windows 2000 server; it again failed to install
the application so this again is contradictory result from Case 1.
I have sent the error report to Microsoft using â??Send error reportâ?? option.
I have searched a lot in the internet for a solution.
Where could I have gone wrong? Tag: System.Net.Sockets.Socket Memory Leak Tag: 96098
Oracle Reference Cursors using Enterprise Library
I have the trouble with the stored procedure returning ref cursor.
I used the code provided by Horst.
The Package ...
----------------------
CREATE OR REPLACE PACKAGE employee_main
AS
TYPE ref_cursor_type IS REF CURSOR;
PROCEDURE get_employees (emp_cursor OUT ref_cursor_type);
END employee_main;
/
CREATE OR REPLACE PACKAGE BODY employee_main
AS
PROCEDURE get_employees (emp_cursor OUT ref_cursor_type)
IS
BEGIN
OPEN emp_cursor FOR
SELECT *
FROM employees;
END get_employees;
END employee_main;
/
The C# snippet which accesses the package...
---------------------------------
public DataSet GetEmployeeData() {
string pkgName = "employee_main.get_employees";
Database db=DatabaseFactory.CreateDatabase();
DBCommandWrapper cmdWrapper = db.GetStoredProcCommandWrapper(pkgName);
cmdWrapper.AddOutParameter("emp_cursor", DbType.Object, 2000);
return db.ExecuteDataSet(cmdWrapper);
}
Another procedure that updates the record with only IN and OUT parameters
executes without problems. However as soon as I try to include parameter
cmdWrapper.AddOutParameter("emp_cursor", DbType.Object, 2000);
it gives me error on execution db.ExecuteDataSet(cmdWrapper):
"ORA-06550: line 1, column 7:\nPLS-00306: wrong number or types of
arguments in call to 'GET_VERSIONS'\nORA-06550: line 1, column 7:\nPL/SQL:
Statement ignored\n"

overload several config files?
Hi
I am building a dotnet 1.1 app, in VB.net ...
I would like to have several config files corresponding to multiple
envirronment (Database, local Machine, Application, User...) and overloads
each, in order to have, by the way, one config.
So I would like to load a config file (app.config) at startup (as usual),
then overload this file with a new file (came from SQL for exemple), then
overload with a second file.....etc....
What do you think about that? is it possible?
Do i must access to each file manually (with xml methods) ? read them and
then construct one config file, and then load it?
Thanks!!!!!!
bye
