yes use MDI like said before. Download some samples/articles here in codeproject and give it a try.

You should try also design usercontrols, and place then inside your form.
Preventing/Instead of creating many forms, you can create many usercontrols and display/load then in the same form.
I think you are going to use this more often.

Either select a different value for it's initial value or after setting the date call the ValueChanged method manually.

dateTimePicker1_ValueChanged(this, EventArgs.Empty);

Language encoding problem

Hi,
Why do I get these funny little squares when I read Arabic data from my database??
I'm using Oracle 10g and it's working quite fine with any language "I can save it and view it correctly using Oracle sql*plus" but it gets encrypted on my window form...

Please help.

Maybe the control which shows your data has a font selected which does not contain Arabic characters. Often the default font is MS Sans Serif, and this lacks many characters. If you change the font to Arial, Tahoma, Courier New or something you should see your data.

Thanks Frank, but no,
I actually tried many fonts including Tahoma and Airal and even Arabic fonts and set the script to Arabic for this control "it's a tree view".. I thought it was as easy as this but no..

Thanks anyways Frank!

If it's not the font, it must be lost somewhere else. Do you fill your tree view with self made code or do you use some sort of data binding? And do you read from the database with a plain data reader or do you use a data adapter plus dataset? Does your connection string contain anything that might enforce a certain codepage? In my experience (though not with Oracle but only with MS SQLServer) using the Visual Studio designer to define connections, datasets and things often leads to strange results

Maybe you can debug or write to the console (or a log file) what characters you actually get in which layer. Or just set up a tiny test application which just connects, reads a string from the table and writes it to the console.

Hey Frank,
Thank you for your replay mate!

I'm glad to tell you that my problem was solved simply by deleting the database and re-install it!!
Very funny eh?? I never thought the problem could reside in the database in this case but it did!

Thank you for your time Frank!

True, and there's no way I'd let the designer interfere in database business!

Accessing a directory on server drive

Hi, I would like to access a directory on a server drive which is D:\myfolder

Is this the correct syntax?

@"\\" + servername + @"\" + @"D:\myfolder"

Thank you.

Thats only correct if the D drive is shared as "D:"... which isnt the case if you just accept the default which is driveLabel(Drive Letter)

if its shared as "Blah blah" your path should read "\\serverName\blah blah\myFolder"

[edit]
you cant share the drive as "D:", it doesn't allow the semicolon. Tested on XP

I'm using

@"\\" + servername + @"\" + @"D$\myfolder"

or if you have a share directory, for example PUBLIC, then use:

@"\\" + servername + @"\" + @"PUBLIC"

and really just the System.IO.Path class in general

Magic: Application runs sometimes and fails sometimes [modified]

I created an application that connects to MS Access Database
I compiled, built, and ran the application, and everything went well

Then I copied the *.exe file to another folder and other computers
I ran it many times with no problems

But, sometimes it does not work and displays the message (Unable to find a version of the runtime to run this application)
And this problem is not solved till I rebuild the source code again

I rebuild and run for 10s of times and the problem appears again

What is the source of such aproblem, and what is the true solution

A couple of suggetions.

Create a set up project or publish your app using click once and install on the other computersrather than just copying the exe.

If you've already made an installer, recompile it first.

If that fails - you may need to reinstall the .NET framework, but if the problem is occuring on more than one computer then it's unlikely to be a framework error.

you will be surprized when you know that this problem occurs with the executable file even while running from the bin directory itself

another thing I recently noticed, is that th file size changes
when it runs proberly its size is 452 kb
when it fails, its size becomes 484 kb

yes, the problem occurs in more than machine

I am installing .NET Framework version 1 and 2 together on the same machine
Do you think I need to unistall one of them?

Did you check the computer where you're experiencing troubles for malware/viri?
A change of file size for no obvious reason sounds very suspicious.

Not long ago I had a problem at a customer's site. One of our applications wouldn't run correctly on one computer - a keylogger or something like this had messed up the command line switches...

Running a virus scan could be worth a try.

I've heard of problems when running v1 (with a service pack if I remember correctly) and then having v2. I seem to recall some major problems when the OS was Win98.

Unless you have a specific reason for having 1.0 or 1.1 - I'd remove all versions then install 2.0, and if needed 3.0 & 3.5 (and relevant Service Packs).

The file size change is worrying - that shouldn't be happening. Sounds virus like to me too. If that's happening on all the PCs then it may be your exe that's infected if indeed it is a virus.

It seems to be really a virus activity, in spite of I scanned my machine and got none infected files

But, I discovered the problem source
The executable file is opened somehow and some bytes are appended making it unusable.
So, the simple solution I did is ....
... I put the file in the READ ONLY access mode
Now, everything works well

Thanks to all participants
