I'm surprised that even NotePad will work inside a Panel in a Windows Form !
I think the following are relevant to your concerns:
on CP, 2004: [^]
on StackOverFlow, 2011: [^]
I would expect "major" non MS applications, like PhotoShop, to never run inside a WinForm, but, I could be wrong.
I think, in general, it is a very bad idea to ever use an instance of another application inside a WinForms app. You are not going to be able to interact with the other application unless you do some tricks like writing a file to a folder that your WinForms app has set a FileWatcher to fire a callback to you when the folder has changed. Back in the stone-age, in the era of COM, SendKeys was a way for VB to interact with other applications, and it was a royal pain in the arse to use (I hope it's extinct, by now).
MS "hands you" standard techniques for automation with the MS Office tools, and IE, and other companies may offer you some sort of API for their software (even hardware) so you can interact with it indirectly. And, of course, you can have a WPF app in a WinForm, and the reverse.
But, I invite you to consider whether it's really wise to struggle to get Application "X" working inside a WinForm.

Hi,
I have WinForm application.
I am trying to display a value from MySQL. The field type is time and it's NOT null.
I am using this code:
lblStartTime.Text = Convert.ToDateTime(sql_reader["start_time"]).ToString("HH:mm");
but getting this error message:
Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.
Please Help..

Maybe this[^] could help you.

lblStartTime.Text = Convert.ToDateTime(sql_reader["start_time"]).ToString("HH:mm");
OK, let's break this down into its constituent parts:
sql_reader["start_time"] returns a Time value.
.ToString("HH:mm"); converts that to a string in the form HH:mm.
Convert.ToDateTime converts that string into a DateTime value.
lblStartTime.Text = which you than try to assign to a Text field.

I tried this:
lblStartTime.Text = sql_reader["start_time"].ToString("HH:mm");
but got:
Error 28 No overload for method 'ToString' takes 1 arguments

What class type is returned from the sql_reader["start_time"] property? Check the documentation to see if it has a ToString method, and if so what is the syntax? You cannot write code like this and just assume it will work, you need to ensure you are using valid properties and methods.

sql_reader["start_time"] is returning a TimeSpan[^]. You cannot convert a TimeSpan to a DateTime, which is why the call to Convert.ToDateTime is failing.
If your time value is always less than 24 hours, you could use:
lblStartTime.Text = ((TimeSpan)sql_reader["start_time"]).ToString("hh\\:mm");
However, note that the hh format specifier only includes "the number of whole hours in the time interval that is not counted as part of its day component":
http://msdn.microsoft.com/en-us/library/ee372287.aspx[^]
If your time values could exceed 24 hours, you would need to format the value yourself:
private static string FormatTime(TimeSpan time)
{
return string.Format("{0:##00}.{1:00}", time.TotalHours, time.Minutes);
}
lblStartTime.Text = FormatTime((TimeSpan)sql_reader["start_time"]);

Why write a bunch of code when any off-the-shelf proxy server will do this for you, and without having to write speerate support for every possible browser.
|
|
|
|
|
One reason not to use a proxy server is that the browser must be configured to work with it, and that's a hassle for the user.
The difficult we do right away...
...the impossible takes slightly longer.
|
|
|
|
|
Compared to the hassle of individually supporting many browsers, it's a very small one.
We also don't know anything of the environment to which this app is being targeted.

I am a beginner to C# while reading i came a cross Cesign Patterns So Can anyone please tell what is this Design Pattern ?

How they help in development of Applications ?

It's impossible to provide sufficient detail to your question in a forum like this. There are plenty of references on the internet that will explain, the purpose of design patterns, and the different types that may be used. There are also books that cover the subject in full detail.

You can buy a book on design patterns and go through them.

Design patterns are a dime a dozen. Since you are a "beginner", then I would focus on the fundamentals first, and worry about patterns later.
Good luck.

The code for that sample is available. Why not just look there?

Hi
Thanks. I am not experinced in programming, was just told that it was a silverlight code that was hard to reuse as an ordinary VS code. But when looking into the details you are right.
Kind regards

I am developing a web application using asp .net 2010 where I need to generate barcodes plus qrcodes dynamically and need to print it on different platform with different sizes.
How to achieve it? Which dll is useful for this? Whether microsoft have in build functionality for this or not? If yes then which DLL?
