I have already developed an application in VB6 which works exactly like the Windows XP built-in "On Screen Keyboard". The problem is I have developed this with using "SendKey" function and the keys pressed passes through the main system messaging loop. I want to transfer the data to other application through "Inter-process Communication" either DDE, pipes or any other IPC method making sure that its process to process not through system messaging queue.
Any help is especially code sample is appreciated....
Cheers!

An on-screen keyboard can be a seriously user-hostile interface.
When I see an on-screen keyboard I assume I can press the buttons on the screen.
Unless the system has a touch-screen I see no point in having an on-screen keyboard.
Don't ever require the user to use the mouse to enter alphanumeric characters; we have keyboards for that.
<Anecdote>
The check-in system at one (or was it two?) of the daycare centers where I used to take my son was such a beast.
It had an on-screen keyboard with the letters alphabetized (rather than QWERTY) and someone (the staff I assume) would hide the physical keyboard behind the computer and pretty much require using the mouse to enter an eight-character code to check kids in and out. 
I always pulled the physical keyboard out and typed in my code; it was so much quicker and easier with much less damage to the carpal tunnel. 
</Anecdote>

You are quite right there but my application requires this. An application to communicate with the other application (both on the same system) i.e Virtual Keyboard sending character by character data to any text editor or webpage but it has to be app-2-app communication rather than communication through system messaging queue.
Any help is highly appreciated.
Cheers!

But why does it need to be on-screen? Why won't the real keyboard work?

The question here is not "WHY", its "HOW" and the simple answer to your question is I am writing a research paper to prove a concept, your efforts regarding code will be acknowledged...
Cheers!

I am filling an Excel spreadsheet using C# and Interop.Excel. When I Excel.Quit();, then manually close and exit Excel the process 'Excel.exe' is left running. (in the windows tack manager). If I do multiple runs, each run leaves behind an Excel.exe process.
thanks Murray D.

Hi
I have application in Netbeans. Can i convert that to C# using JLCA or not ?
Do i have to convert the application to J# first. And would that be easy task ?
And does JLCA does a good job and would i be able to add code in C# to that application after conversion ?
Thank You
James

Converting from Java to C# shouldn't be that hard. You'll have to do it by hand AFAIK...

I've use JLCA to some effect, however you still end up having to fix a lot of code by hand.

Using the code below. Set up a button that would take the value of textbox 2 so that I can pass it to another part of this application? How would you suggest setting up two other queries that would join with the first query to fill in other textboxes?
EX:
Textbox 1 = query1 (main query) textbox 2 = query1 (main query) textbox 3 =query2 (sub query) textbox 4 = query3 (sub query 2)
Sub query -> select column a from table2, table1 where id.table1 = id.table2
And then
Sub query 2 -> select column c from table 2, table 1 where id.table1 = id.table2 and column a – column b
Thank you in advance
public Form1()<br />
<br />
{<br />
<br />
InitializeComponent();<br />
<br />
}<br />
<br />
string tb1 = "*";<br />
<br />
string tb2 = "*";<br />
<br />
private void textBox1_TextChanged(object sender, EventArgs e)<br />
<br />
{<br />
<br />
if (textBox1.Text.Length > 0)<br />
<br />
{<br />
<br />
tb1 = textBox1.Text;<br />
<br />
}<br />
<br />
else <br />
<br />
{ <br />
<br />
tb1 = "*";<br />
<br />
}<br />
<br />
performQuery();<br />
<br />
}<br />
<br />
private void textBox2_TextChanged(object sender, EventArgs e)<br />
<br />
{<br />
<br />

<br />
{<br />
<br />
tb2 = textBox2.Text;<br />
<br />
}<br />
<br />
else<br />
<br />
{<br />
<br />

<br />
}<br />

<br />
}<br />
<br />

cmandy,
This sounds a bit homework related...

At the core, if this is not homework, then the answer is, 'don't do this'. Your code is wide open for SQL injection attacks. Give your variables real names, use stored procs, and use delegates to get different classes in your app communicating with each other.

That is a pretty big topic. Good luck

That's a pretty open ended question. Did you have a specific type of simulator in mind?

Hi all,
In my application when some works are finished the program should automatically send an email to some persons (their emails are known before). The point is, different user can do this operation on different PCs, so I want to get the standard email account on the PC where my application is started from.
Using the class "MailMessage" like:
MailMessage message = new MailMessage(
"myhardcodedemail@myprovider.com",
"email.address@mycollegue.com",
"The Subject.",
"Some useless text to build the body….");
works perfect, but I don’t want to write the “from” email hard coded, I want to get it programmatically (All users are using MS Office Outlook 2007 – if this is important).
Another Question is: is it possible to send at once the email to many people (how should the “to” field looks like ?), or I must send it to each one (repeating the step for each user – this works).
For any idea thanks in advance.
Best Regards,
Emil

You might want to consider querying a remote service (or data store) to get the information (such as the user's email address) specific to the user.

Yes. See the CC property.

If you're using Outlook/Exchange, when a user logins in on Windows, the users e-mail address is associated with their Windows login(depending on how you're setup but this is the typical scenario)

I have something really strange happening that I want to run by you folks. Frequently when I add a new button to Form1.cs[Design] the button appears in the IDE, the button is listed in the Form1.Designer.cs, The button is not hidden or behind another form, but the button does not show in the compiled program. This happens when compiling under Vis 2005. I had thought that maybe there was a defect in my compiler so I reinstalled Vis 2005 and I get the same results. Whats really strange is when I take the same code and recompile under Vis 2008 the button appears in the compiled program and works as it should.
I have now discovered that after compiling the code with Vis 2008 I can go back to Vis 2005 and recompile the code that didn't compile properly and it will compile. Vis 2005 will run properly for a while until it repeats the problem above which I find I can fix each time by running Vis 2008.

Hi George,
very strange indeed. I've never seen that with my Visual 2005.
There are some bugs in VS2005 C# Express Edition, where Visual gets confused
and I have to delete the bin and obj directories, then rebuild.
You could try that. If it does not help, I Can't help you unless you send
the entire project I'm afraid, so I could have a look. No guarantees though.

I ran Vis 2008 and now all is well. I don't know when the problem will occur again but when it does I will try your suggestion.

Is that an inherited button? Did you check what's the different between VS2005 and VS2008 for the portion related to the button in the InitilizeComponent()?
