Close them - they are a finite resource. At present it works, but suppose they add another 10 users in six moths time. Will it work then? Or will you have to drop the top-priority task you are working on then and fit long nights into retro fixing your software? I know which I would prefer.
Do it right the first time: then you hopefully won't get any nasty shocks.

Always dispose the connection once the work is done. In case of ODP.Net, close and Dispose. Never leave a connection open.

I close and open it again later -- why dispose?

Hello,
I wrote my own installer in C#. It's all finished, except I'm having trouble with file type association, specifically file icons. I made my installer extract .ico embedded resource from its own .exe into the installation directory and set the registry key's DefaultIcon value to the icon file's path. (e.g C:\Program Files\Moonlite Map Studio\FileIcons\gx.ico,0), however in Windows Explorer only the .txt file icon shows up, so something must obviously be wrong.
What is the normal method to do it, and would I be able to do it programmatically?
Thanks,
Theo

It seems Windows only likes icons if they're embedded in resource .dlls. How can I do this?

No , windows use icon from dll , and exe files
I think the Structer of EXE .NET resource is different than other EXE
May be you must add icon your exe 16*16 , 32*32 , 48*48
any way use resource hacker for this Resource Hacker[^]
to check your exe and icon location ,
I know nothing , I know nothing ...

Hi,
I don't have very specific answers, however:
1. I'm pretty sure it can all be done programmatically.
2. You will have to provide more than one resolution (all square, and multiples of 16). Windows will use different icons on different occasions (Windows Explorer, large icon/small icon; taskbar buttons; desktop shortcuts; etc); and it differs for different Windows editions (typically newer editions such as Vista/Win7 like to also have larger icons, up to 96*96).

I need to get an image from the system clipboard (Clipboard.GetImage()) and serialize it to a file. The end goal would be to, at a later time, deserialize this image and put it back in the clipboard.
I can't figure out how to successfully serialize the image. I tried creating a serializeable class that contains an image object, but I get the exception
"The type System.Drawing.Bitmap was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically."
I tried using XmlInclude but am either doing it wrong or it does not resolve the problem.
Has someone done this before?

So you're saving an image as XML?
This is why we need 1TB+ harddisks these days.

Hi , have a good day
When I want to output some result to console, from a Windows Application ( GUI )
I do this :
Project -> Project Properties -> Application -> Output Type: "Console Application"
int a = 17.5;
int b =5;
a= a * b;
datagridview1.DataSource = datatable;
Console.WriteLine(datagridview1.Rows.Count);
Console.WriteLine(a);
Thank you

Very illuminating. Now, why did you post that?

And your question is...?
I prefer to attach a console like this[^].

I'm doing some work with Active Directory using C# and the DirectoryEntry object. I'm fairly new to C# and exceptions, go easy on me!
Some Code:
DirectoryEntry entry = new DirectoryEntry ( LDAPServer, domainAndUsername, Password );
try
{
Object obj = entry.NativeObject;
}
catch (Exception ex)
{
ErrorMessage = ex.Message;
return false;
}
Now, it seems that when binding to the DirectoryEntry fails, the exception is called. The error is returned as a string, which gives me an idea as to what happened, But how do I test what the error was programmatically? Is there some kind of numeric value as well in the exception that I can test?
Basically, I want to know if the connection failed because of a bad ldapserver, or a username/password mismatch etc. I'm trying to create code that does a fail-over to a second ldap server if the primary ldap server is offline. I don't want to jump to the second server to retry the authentication, if there was an error with the credentials.
Is there another exception I can test for here? How would I found out what other exceptions are available for this object?
Any help you could give would be great.. Heck, I'll buy you a beer!

One way to do this is to have a series of catch blocks.
try
{
Object obj = entry.NativeObject;
}
catch (System.UnauthorizedAccessException e)
{
MethodToDealWithThisTypeOfError(aParameterFromEventArgs, anotherParameter);
return false;
}
catch (System.DivideByZeroError e)
{
MethodToDealWithThisTypeOfError(aParameterFromEventArgs, anotherParameter);
return false;
}
finally
{
MeassageBox.Show("This happens regardless of errors", Application.ProductName);
}
and so on.

Here is a reasonable article[^]

Hi,
I am able to extract the text from the PDF file using the PDFStripper, but I would like to read the Table of content of the PDF document. How can I do that? How do I know the Page I am reading is Table of Contents? and also how to differentiate the Chapter heading and the subsection of chapter of the Table of Content?
Any help in this is highly appreciated.
Thanks
Neil

Your best source of information is the people who wrote PDFStripper, but I think some of this would be subject to how the PDF is organized and written.
If PDFStripper doesn't provide any data to differentiate this, you'd have to implement logic (probably fuzzy) to try and analyze a page to see if it MAY be a TOC. The problem would be determining where the TOC ends.
You've got the same problem for the other parts of the document you want to pull out.

Hi there,
in an application which I developed on a Windows XP computer in Visual Studio 2005 Express with C#, I set a tooltip in a MouseMove event of a panel. On that environment, everything looks fine.
Then I loaded the source code on a Windows 7 64 bit computer in Visual Studio 2005 Professional, started the application, and found that the tooltip was terribly flickering, even when I did not move the mouse.
I added variables for storing the last mouse position, and in the MouseMove event I leave now the function when the position has not changed. Now the tooltip looks fine on Win7 also.
For debugging purposes, I set a break point on that return statement, I really get there...
I.e. a MouseMove event is fired though the mouse is not moving.
What are your experiences with MouseMove and tooltips with respect to Windows 7? Looking forward to your statement.
Regards,
Bernhard

I just had the exact same experience with tooltip flickering inside of a DataGridView. This flicker was also found only on Windows 7 and not on XP and was caused by the MouseMove event firing repeatedly in Windows 7 when the mouse is not moving.
For now I have applied your same fix. If I find the underlying cause I will try to follow up.
