I think the only way is to trap any exceptions thrown by the Open method, I don't know and cannot see of any other way.
As of how to accomplish this I wouldn't have a clue at the moment and I'm too lazy to google it

The only other way I can think of is open a connection the server and query the system tables for the database in question. This is of course not a very good option as it requires a higher level of credentials and the storage of two connection strings.

I have created a C# windows forms app.
On a certain click event I perform a console.writeline("Message Text").
The program buils fine, and runs without an error, but I don't get to see any output in a console window.
What must I do to see the output?
|
|
|
|
|
Do you use Visual Studio as your IDE ?
When you create a new Console Application, then you will get an empty Main method.
Just type : Console.WriteLine("Message Text");
It will show "Message Text" in ConsoleApplication.
|
|
|
|
|
there is an output window (in the menu -> view -> Output).
It should come in there somewhere. (note that other stuff comes in there is well.)
you could do this to filter a bit:
<br />
console.writeline("");<br />
console.writeline("Message Text");<br />
console.writeline("");<br />which will write an empty line before and after your text.
Good luck.

You can change the executable to compile as a Console App, nothing stops you from displaying Windows Forms. The only difference is, is that a Console is displayed if not run from a console. If this is only temporary for debugging purposes then you can change it back to a "Windows Forms" project when building for release.
You can also run it from the command-line without having to compile it as a Console Application and that will display the information (basically the Output window mentioned above does exactly this).

I have a stored procedure that returns XML using FOR XML AUTO ELEMENTS, but there is no root element in the returned value.
I feel this may be the source of some errors im getting when trying to load the returned value into an XMLDataDocument.
Whats the best way to get a "root" element to ecapsulate the data?
Is there a way to make it return the results with a root? or a simeple way to add one to the datadocument in preperation before placing the returned value into it?
Thanks.

You might be able to create a XmlDocument with a base root and then set the roots innerXml to your xmldata.
Something like:
<br />
XmlDocument xmlDoc = new XmlDocument();<br />
<br />
xmlDoc.LoadXml("<root></root>");<br />
<br />
XmlNode root = xmlDoc.DocumentElement;<br />
<br />
root.InnerXml = your_xml_data;<br />
Not sure if this will work on first try. Havent got a compiler here but I've
set node.InnerXml successfully before.
Hope it works for you.

Python has library 'difflib' which can be used to find coincidence percent between two sequences (strings). I am looking for the way to do the same (compare 2 strings) within .net platform.
So what is the name for an algorithm I am looking for? And where to look for it?

Hello everyone,
My problem is that I want to -simply- write selected images to CD/DVD in my app.. I searched for the xp burn area but found nothing (you know, you can say "burn this" to any folder and XP copy this file/folder to a burn area)..
Also the nero sdk may be too complicated..
What can I do to accomplish this task
Best regards..

Would someone please help me with this problem:
I have an expando on my MainForm that takes care of my menu, and I also have a MenuBar on the same form that also provides shortcuts to the items in the expando. After using the expando for a while, I then use the MenuBar and then suddenly my system crashes and an error: "Handle is not initialized " appears. (The expando and MenuBar sometimes call DataSets)

What is the code to find out the number of pixels contained in an image and what is the code needed to draw a histogram.

Loop through the pixels, calculate the value that you want the histogram for (for an example intensity), and count how many there are of each value. Draw a diagram from the count.

Simple counts don't graph nicely :p

Hi All,
I am having MFC ActiveX control which gives the graphical environment
I want to build the same control in C# ActiveX control.
I can use class library with user control to implement this but the problem is that the existing control is using many supporting libraries and included some .h files.
I can rewrite the basic code written in control but what should i do about the supporting libs and .h files.
OR
Is there any way u can suggest me to convert the existing control to the user control in C# and i can use the existing .h files as it is.

Hi I faced a problem when converting for VS2002 to VS2005.
'Cannot declare variable of static type 'System.IO.File', because i declare an instance variable of this Type in my Old Code.
When i look in detail, the defination of System.IO.File has been changed 
Previous Defination : public sealed class File : System.Object Member of System.IO
New Defination : public static class File : System.Object Member of System.IO
Does any body have solution, i cannot change my code,because its lot of code.
I wonder Why Microsoft Did this.
Regards

Microsoft provides two versions of the class now. File exposes its methods entirely static and FileInfo exposes instance methods. Both provide the same functionality, just in different ways.
In any case, you'll have to modify your code. You simply don't have a choice here, since you can't create an instance of a static class.
You'll have to do a Find/Replace and change your instances of File to FileInfo.

Generally true, but both classes existed already in 1.1. The reason that MS didn't make File static in 1.1 is simply that the operator didn't exist in that version.

I think he's a bit confused. He says he's using VS 2002, which is .NET 1.0... He could have used 1.1 with it, but I doubt it he's got it.

Why have you declared a field of type File? You cannot instantiate it (as there is no public constructor) so what are you doing with it?
|
|
|
|

Do we need to register everytime we install in different machine or is it enough for me to register once in one machine and then by using the same registration can i generate new registration key so as to install visual studio 2005 in multiple machine..
