You can launch the JIT debugger from the batch file (with the %WINDIR%\System32\vsjitdebugger.exe util), after you've successfully started your app.
For instructions on how to do it refer to this link: Answer 3[^]

I use the following for debugging on my dev machine
System.Diagnostics.Debugger.Assert(false);
When it executes it pops a dialog that asks for the debugger to run via the 'retry' option on the first popup.
Once the debugger starts there is a break point on the above line.
There are limitations to this such as where the app is running and timeout issues with execution threads (with the debug line).

Hello, I need to add element host to one column of my datagridview and attach a user control to each element host. Is there anyway to implement this? Datagridview is in windows form and I designed a user control in WPF with Avalon library.
Thanks,

Hello,
Is there a way to draw a rectangle on top of all windows form application that we can see threw it the other form controls? (like thick box in asp.net).
or if there is a transparent control that we can see thew it a control behind him...
Thank you very much

Could be helpful if you share what the use and purpose of this transparent overlay is.

i have a pdf in my form and i want to cover him with a transparent control to deny the user to interact with him because i want to deny him to print and save the pdf.
i tried multiple libraries to set this security but the failed with the new adobe reader that comes with a little toolbar right a the bottom of each page (on mouse over) so the user can save and print the pdf.

Um.
You do realize that any protection you introduce like that can be got round in about half a dozen mouse clicks? For example, Chrome provides both "Inspect element" and "View source" which would either get the complete text or the url which links to the PDF. With that, it would be a simple matter to download it in the normal way...
What are you trying to do that you think an "untouchable" PDF file is a good solution?

That's handled by the security settings in the PDF document. What you're doing is just a hairbrained scheme that is easily defeated by about half a dozen ways that I can think of in about 5 seconds.

first,the security in the PDF document didn't work (using 4 different libraries) with this little toolbar at the bottom,second how you can defeat this in 5 second? i deny you to reach the PDF to save it,it's not a web application that you can use developer tool or firebug or .. to reach the PDF,it's windows form application

How about Acrobat?? Works perfectly. 3rd party libraries usually don't have great support for the security features, if at all.

Hehe. Actually, I CAN defeat it. Since it's Windows Forms and not a web page, it'll take a bit longer, but still very much under a minute. Yes, I already have the tool written to do it.

Hi everyone
We use of "Add New Data Source" (in the visual studio) and then select a dataset for connect a database in the C#, Is it possible to make a new database in the "Add Connection" window instead "Select or enter a database name"?
Thanks
|
|
|
|
|

I have searched on the internet and it looks like nobody tests it and its first time,could you test it ,please(it doesnt get many times)?I enter the new name in the "Select or enter a database name" field and it asks of me:"The database "mydatabse" does not exist or you do not have permission to see it.Would you like to attempt to create it? when you click ok it makes it!

Congratulations! You tried it and found that you could. You answered your own question. What exactly does this have to do with C#?

No this is not the correct way. Your question has absolutely nothing to do with C#. And most likely you are not going to be creating databases in C#.

No. The better way is to use a database creation script. If it is really needed to be done, then the C# application would run the database creation script and create the database for you through SQL Server. Most of the time, a database should already exist and have been created before you even write any application code.

Uh huh. It probably only supports SQL Server and I doubt it gives you any control of the settings. As such it's not a good way to do it.

When we create database connection in C# lets say to SQl server, why it is recommended to use connection statements within using? I know using makes CLR reclaims memory when control is coming outside of using by calling Dispose(). But SQL server connection should be a managed code and using is usually used for unmanaged code. I mean we create SQL Server connection objects from .NET libraries, so why is unmanaged? Really looking for answer.

Hehe, as you said yourself, it's not limited to unmanaged code.
munishk wrote: I mean we create SQL Server connection objects from .NET libraries, so why is unmanaged?
Unmanaged code often holds handles, and other stuff that needs to get rid of "exactly once". A library is loaded once, and unloaded once.
For a SqlConnection it adds other benefits; not only does it close the connection once the object gets disposed (something that should be done "once" again, in a destructor-type method), it also clears the largest fields (and disposes embedded disposables), helping the GC.

Not generally it doesn't. It returns the connection to the pool. If the pool is configured explicitly (non-default settings) then it will.

But can we say that creating sqlconnection is unmanaged resource? This is even stated in Albhahari book too. I am still looking for clear answers.

There's got to be unmanaged objects deep in there somewhere -- named pipes, network sockets, I don't know.

No you can't say that because it is managed class.
At some point that class or some other part of the .Net API (not visible) is interacting with unmanaged resources. Just as many other managed classes do.
However that has nothing to do with your use of it.
