When I create a remote object (Activator.GetObject), the first method call on the remote object is EXTREMELY long, generally around 30 seconds. The remote object is created on a local network host. Is this normal behaviour? Is there a way to reduce this time?

Hi,
I have a slight problem and would appreciate any help.
trying to write a program where a TreeView clears and re-builds a ListView's contents depending on what node was clicked.
Some of the TreeView nodes requires icons to be displayed on ListView, some don't. However if you assign a null value to the SmallImageList property of the ListView, it still keeps the icon place holders resulting in slightly right aligned text in the ListViewItem.
Is this a bug or there is another way to disconnect an ImageList from ListView?
thanks

Try to Decompile  this .NET demo application protected with my simple obfuscator 
your opinion is a lot important. tnx in advance for your attention and eventual suggestions.

Well what exactly do you want to hear?
You will know yourself that if obfuscates rather well  . Even strings are hidden very well which is not 'standard' for obfuscators. I think this is probably also the reason why the IL code is that extreme long. It has more than 9000 lines where I would expect (in such a simple program) not more than 10 lines. If this scales up in bigger assemblies that would really be a problem...

thanks! for to have dedicated to me little of your time
the new version has been remarkablly upgraded with a new polymorphic engine 
the software originates has them 6kb lines of code. protected code 20 (considering the obfuscated string). this is the price to pay for one good protection. assembly the little longest one is the last one of my problems.
with my obfuscator, at moment, I succeed to block:
- Reflector;
- Spices.Net;
- Anakrino;
- Remotesoft;
- Decompiler.Net
...and the mass of hacker occasional that they want to steal our code

What would interest me if this "growth" of size is linear or just one time per class/assembly or whatever. If an already large assembly gets more than twice the size when obfuscating its a bit too much (at least in my opinion). I also noticed that a little test app of mine which only shows one MessageBox runs noticeably faster than yours.
btw: Is your homepage broken? Except for external links nothing seems to be linked together correctly. I ask because I wanted to try your tool myself...

perhaps in part your reasoning is right 
I try the maximum emergency paying on the largeness of the file. your file are faster only why it is smaller !
I am of the idea that puts into effect them to it obfuscator does not serve to nothing. enough not to change name to the methods. a method works equally even if it calls itself "a" instead of "SerialNumber"  ...I render incomprensibile the structure
my web site is in maintenance. I must test my obfuscator with the DLL assemblies. and then the public
for my obfuscator still I have not decided if to distribute free of charge or to payment...i must support my company and my creativity

Spent most of the morning looking at how to link or include config files.
For example, lets say right now I have a database connection string in my web.config. I want to break it out into a different .config file that is referenced by the web.config, but the application/web-service itself is otherwise ignorant.
I want to know if there is a built in facility/syntax for this that I'm plain overlooking.
In my particular work environment, developers are technically not allowed production access, including knowledge of passwords.
We are also expected to have seamless installs.
Currently, after installing, we have to go and make multiple manual config entry changes in production, introducing the prospect of typos. This is not seamless.
What I would like to do is seperate all the configuration settings that are machine specific and have a low change frequency into a seperate config file, so that the average install can be ignorant of them while still being able to add entries to the main config file.
so, instead of web.config looking like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<!-- DEV SETTINGS -->
<add key="LookUpConnectionString" value="server=xxx;uid=xxx;pwd=xxx;database=xxx"/>
<!-- TEST SETTINGS -->
<!--<add key="LookUpConnectionString" value="server=yyy;uid=yyy;pwd=yyy;database=yyy"/>-->
</appSettings>
...
</configuration>
it looks something like:
<configuration>
<appSettings>
<import name="LookupConnection.config"/>
</appSettings>
...
</configuration>
with LookupConnection.config containing the DSN info.
Ideally, without having to make a lot of code changes, as I'm trying to streamline an installation process, not re-write the existing application.
Am I dreaming a pipe dream here?

The appSettings key has a file attribute for this purpose:

Hi
 Having a bad week (and it's only Monday)...
We have an inhouse component that relies on a 3rd party SDK. I was told the latest version of the SDK was build using VS.NET, so we had to upgrade. I've just built the new dev environment, installed VS.NET 2003 - (you can see where this one is going) - built the component, only to find there are missing dependencies. The 3rd Party relies on MFC70.DLL and we're now using MFC71.DLL.
Questions
1) Can I run my process where my EXE links into MFC71.DLL, and also links into a 3rd party DLL which inturn links into MFC70.DLL.
2) The 3rd party also has an NT service running, which will have MFC70.DLL already loaded. Will that impact me as well if my exe (also a service) uses MFC71.DLL.
This is a really naff situation to be in, but I can't downgrade to 2002 .
Any help really appreciated.
Regards
Angel.

 I presently have a winforms app being started by another program (the
application updater). The application updater does not open with a form but
checks to see if updates are available and if so downloads and installs the
latest version. When the download is installed the application updater
display a form informing the user the install is complete and to click on
okay to use the new version and then restarts the winforms app.
My question is that during the time the update is being downloaded the
normal application is still able to be run. I would like to change the
cursor to the wait cursor while the download is going on and on completion
return it to the normal cursor for them to answer the question. However no
matter where I put the change for cursor in the application updater it is
ignored. I assume because no window is being opened and used during this
time.
Can anyone help?

can any one tell me how to use a DLL made in VS C++ 6.0 to use in a VS C#.NET project. I tried adding one in my solution through referencing it in the C# project but it gave the error that "the DLL is not a valid .NET DLL" ....any suggestions?

I am using MS VS .net. I have created a project and associated solution. I now want to take a snapshot of my current project before I move on with development in case I mess something up. I can't ficure out how to easily make a copy of the solution.
Any suggestions?

It's all file based, so for the simplest form of version control you can just make a copy of your solution's directory.

I did make a backup. Then I tried to open the solution from the new directory and could not. Why couldn't I?
|
|
|
|
|
Did Visual Studio give you an error message? What happened when you tried to open the solution? Did the copy you made contain the .sln file as well as any related project directories?
The solution file (.sln) is just text, so you can open it in notepad and see what it contains. Among other things, it will specify the relative location of the projects in the solution. If any of the projects has an invalid path in the solution file, you'll get a message box in Visual Studio telling you it was unable to read the project file.

The directory where the working files are located is in d: I copied all of the files into another directory on the same drive and called it xxx. Try to open the solution but VS can't even find it. It seems to want to look in a directory in C:/my documents/visual studio projects which seems to contain directories of solutions I have created. In each directory there exists one file. The file is called a vidual studio solution object. at the beginning of this file are the following lines
Microsoft Visual Studio Solution File, Format Version 8.00
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "DACISV2", "http://localhost/DACISV2/DACISV2.csproj", "{CA22A93D-314E-4550-AC4B-ED5AC663B311}"
ProjectSection(ProjectDependencies) = postProject
EndProjectSection
EndProject
First what is the aplhanumberic code FAE04.... Second if I simply duplicate this file and create it in a folder in the c dir that matches the copied solutions name (xxx) then edit the object to change the path to point to the new directiroy and file I can open the project BUT it doesn't work.....
This seems awfully complicated. Surely there must be a simple way to make a copy of a solution.
I really appreciate your assistance.
Brian
P.S. I never did find a .sln file!

The snippet you posted is from the .sln file. (Do you, by chance, have "Hide file extensions for known file types" selected in your folder options? I have never understood why this is the default, but this is usually one of the first things I change when I sit down at a new machine.)
The alpha-numeric string starting with "FAE04EC0" is a GUID (Globally Unique Identifier) representing a C# project file (.csproj). The second GUID (the one that starts with "CA22A93D", in your case) respresents the actual project (DACISV2).
I made the assumption (a bad practice, I know) that you were working with WinForms applications, but I see from what you posted that you're actually working with web apps. The location of the code files can vary depending on how you added them to the solution, but by default they'll be in C:\Inetpub\wwwroot\{ProjectName}. This will be different if you didn't go with the defaults when setting up IIS on your machine. You'd need to make a copy of those folders as well.
To restore the "backup", either replace the newer version with the saved version and go about your business or alter the saved solution file to point to the backups you made of the projects. You'd just change the path in the solution file to point to the new location. e.g., "http://localhost/Copy of DACISV2/DACISV2.csproj"
If you don't want to have to deal with all this stuff, there is a good source control tool called SourceGear Vault[^] that is free for single users. Using a source control system adds a certain amount of complexity itself, but it can also add a lot of flexibility when restoring a previous version.

Hi all !
I have a RichTextBox control containing red-colored text "Hello world." and
I need to get (for example but not strongly !) the following html-page:
<html>
<body style="color:red">
Hello world.
</body>
</html>
Does FCL contain any classes and methods to solve my problem ?
Many thanks !

hi
i am working on a full screen app, and was wondering if there is any way of hiding the taskbar.
|
|
|
|

Yes, in the form that you want to fill the screen, handle the Load event inserting the following code:
this.FormBorderStyle = FormBorderStyle.None;
this.Location = new Point(0, 0);
this.Size = new Size(Screen.PrimaryScreen.Bounds.Width,
Screen.PrimaryScreen.Bounds.Height);
You may want to set the form's TopMost property to true as well.
Hope that helps. 
Happy Programming and may God bless!

Hi
My company is hiring and I'm stuck with writing a meaninful set of questions so interviewers can ask the prospects about .NET and ASP.NET
This are Senior level Developers positions that will be in charge if developing from specs or sometimes without specs web-based and smart client applications.
On top of .NET they require amomg other things
- N-tier architecture
- component development
- UML and RUP
- Data modellling
- ORACLE
- PL/SQL
Any how , can someone point me to standards question that can ask to determine the level of knowledge on ASP.NET and .net in general.

Hi,
Well a good start would be with the garbage collection. Ask them what is garbage collection, and the mechanics of it. Make sure u read about 1'st and 2nd generation garbage collection. this will help you understand and also compose some questions.
Also you can ask them about the .NET tools, such as ILASM-ILAssembler, ILDASM-ILDisassembler, and of course IL. IL is the bytecode of the framework. Any experienced developer would certainly know a bit about IL, Intermediate Language.
And for asp.net I would ask about security. Such as Forms.Authentication namespace, simply for the reason that if any developer has worked with asp.net they would definatly work with Asp.NET security namespaces. Also I would definatly get into the DataGrid control since its advanced and very powerful.
Maybe Class Libraries can fit in there too, and component development.
