hi all
i have developed an windows application and want to build a (setup project) for it !
but there is some problem !
1) how can i find if there is another version of this application
2) warn user to repair or uninstall after installing new version! (like most of other software s)
3) find if there is any sqlserver2005 instances run on the services.msc if there is an instance but is not run!, then run it (without need the user to run this services manually)
please note me any thing in your mind about any of above sections!
thanks in advance

Hey my frnds .... I was working on a Dial-up networking for my customers ... which accepts connection from another PC by just dialing (only a modem and a phone line is needed in both PCs) which is not the concern of C# in my case .... But if I didnt not hide this connection from network connections in windows , another persons(may b professionals) can change things and might mess up my work .... So what i wanted here is that ... I want to write a C# code which will hide the connection i created and allows the user to run the connection @ any time with the help of C# code .... is that possible ... if yes please help me
Thank you

Sounds user hostile. A user has the right to be able to screw up his system any time he likes.

Hi all,
I am making an application comprising both C/C++ and .Net environments (for different modules). Both C++ and .Net modules create logs in some XML files. But I am now facing many problems in maintaining all the log files (mostly because of their sizes).
I am planning to create my logs in some database. But I am not familiar with using any database with C++ or with .Net code. Here are my requirements:
1 The very first requirement is that database should be free to use.
2 database should be able to connect with both C++ module and .Net (C# module)
Can anybody suggest me any such database that can be used freely. Also help me in knowing some tutorial by which I can connect my application with that free database.
Thanks in Advance

1. - Microsoft SQL-Server Express is for free, but you can't use databases with a size over 4gb.
- There also exists a free database version from IBM DB2.
- At least you could look for an oracle version (I thought there is also a free version, but I'm not sure).
[Edit:]You could also use a MySQL database. But its not my favorite![/edit]
2. You should be able to connect to all named databases above!
Greetings

Free stuff is often not worth the price.
I wouldn't use a database as a log file. For one thing, how does the application log a message saying it can't access the database? A logging system should be as simple as possible, with the fewest points of failure you can achieve.
I tend to use SQL Server Express for the little applications I write. A customer can then upgrade to full-blown SQL Server if they choose.

For something like log files, you don't really need a full-blown database.
If you just want a database to make working with large files easier, I suggest you take a look at SQLite[^] (.NET wrapper[^]). It is not a database server, but a library that runs directly in your process.
It's ideal for client-side databases where you don't want to deal with deploying a database server; it's just another .dll to be copied with your app.

Using JQuery[^] its as simple as this
function ButtonClick()<br />
{<br />
$("element_id").hide();<br />
}
I know the language. I've read a book. - _Madmatt

There is no facility to do this in the TableLayoutPanel methods and properties. You cannot make rows visible or hidden. You'd have to fake this using some other method.
Off the top of my head, you could move the section you want to a seperate TableLayoutPanel, which itself is put in a Panel control. You can make the Panel visible or hidden at will, taking its child controls with it. Or you could do it the other way and put your child controls in a Panel, then put the Panel in the TableLayoutPanel row. This method may not be feasible depending on your situation.

Use SizeType.Absolute with a value of 0F (for the RowStyle) to hide a particular row. For example, if you had 3 rows and wanted to alternately hide and show the middle row, you could use the following:
// Hide middle row.
this.tableLayoutPanel1.RowStyles[ 0 ] = new RowStyle( SizeType.Percent, 50f );
this.tableLayoutPanel1.RowStyles[ 1 ] = new RowStyle( SizeType.Absolute, 0F );
this.tableLayoutPanel1.RowStyles[ 2 ] = new RowStyle( SizeType.Percent, 50F );
// Show middle row.
this.tableLayoutPanel1.RowStyles[ 0 ] = new RowStyle( SizeType.Percent, 20f );
this.tableLayoutPanel1.RowStyles[ 1 ] = new RowStyle( SizeType.Percent, 20F );
this.tableLayoutPanel1.RowStyles[ 2 ] = new RowStyle( SizeType.Percent, 20F );
(Note that the "Percent" styles don't actually need to add to 100. The individual values are relative to the "total" of all the percents, so each row in the end winds up using 1/3 of the panel).
(Also, you should group the controls on the "hidden row" in some way so you can collectively disable them so they don't get focus when hidden via tabbing).

Hello
When I have a look at the Color and the Font property I use in my designer, the language in the two editors is a different one.
The FontDialog is displayed in German (i assume because of the operating system's language).
But the ColorDialog is displayed in English.
How can I change the ColorDialog's language to German as well?
I have searched here for articles about ColorEditors and found this one:
ColorEditorEx - An extension to the ColorEditor to support translucent colors[^]
On the screenshot the language is German, but when I open the application, its english again (the tabs).
I hope someone can tell me how it is possible to change the language of the ColorEditor to german
Windows language = german
Visual Studio = english (maybe thats the reason?)
Thanks for your help in advance

Hello to all.
I have a problem, I need to encode a password string in SSHA(this uses SHA1 in some way). I don't know how to do this. I didn't find any article on the net about that.
I need to do this because I'retrieving UserDetails from OpenSSO server, and the password retrieved is in SSHA encoded, and I need to compare with the given one password that's the input for my method, but to do that I need to encode this using SSHA.
Some ideas?
Thanks in advance.

Thank you for your post, but I found this article before posting the question. It doesn't help me.
I think right now to change the strategy in my application because of that.

SSHA is the default encoding in openLDAP - I havnt seen many/?any stand-alone implementations of SSHA, so, you could download openLDAP, pull the code you need out of that !
ps .. its also used by the htpasswd function in Apache, so you could d/load that as an alternative to openLDAP

Thank you for your advice. I'll try to solve my problem.

I found a plausible implementation that wouldve been easier to start with, but Im at home and its at work 
There is a good discussion with java and perl implementations at http://www.securitydocs.com/library/3439[^]

If you have a look, there is a forum for WPF, WCF et al.
Ask there, they might be willing and able to assist.

There are many free articles introducing WPF on the net, including here on CodeProject; go to the articles page and look for the headings. I have not tried WCF yet but I suspect the same holds true for that.

There's a reason they aren't free. The authors have to eat, so it's not fair to expect them to spend months writing books on complex topics, and then expect them to give them away.
If you don't want to buy a book, then read through the WPF docs on MSDN, and read through the articles by Josh Smith, Sacha Barber and Karl Shifflett here on CP.
