I have a struct that holds two longs (Low and High). This struct is used as a property (FullRange) in a user control(RangeControl) which I've dropped on a form. The values are not being serialized in the InitializeComponent in the form's designer.cs file so are therefore not persisted.
I expected to see something like
this.rangeControl1.FullRange = new Range((long)1, (long)50);
If I change the struct to a class it creates a variable for the property in the InitializeComponent and saves the values.
range1.High = ((long)(50));
range1.Low = ((long)(1));
this.rangeControl1.FullRange = range1;
How can I get the struct to persist?

7 hours later and solved it - I had a problem with my CreateInstance override so the designer wasn't able to call the contructor to be able to do the serialization. It's unbeleivable just how tricky this was to do!
Credit to the code in this[^] article which I used for comparison to my code to trace the problem.

duh !
Are you serious man?
first this is a C# forum not an algorithm and walkthrough forum.

Don't use words like urgent. That is a sign of just ignoring your request for help. As the other poster mentioned, this reeks like homework. Do your own work.

You want a magic number in C#, urgently? How about 7? Alternatively, how about you urgently learn how to do your own friggin' homework yourself you sad sackless loser.

Not really. I just couldn't be bothered to sugar coat my opinions for Loserville's Village Idiot.

Hi,
I was trying to connect Action Remedy System Database(Application developed by BMC software) using C#. It throws the below exception
ERROR [S00] Driver]Cannot open catalog; Message number = 90
ERROR [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed
ERROR [01000] [Microsoft][ODBC Driver Manager] The driver doesn't support the version of ODBC behavior that the application requested (see SQLSetEnvAttr).
Code for connection is as follows:
OdbcConnection odbcConnection = new OdbcConnection();
odbcConnection.ConnectionString = "Driver={AR System ODBC Driver};arserver=servername;arserverport=serverport;uid=userID;aruseunderscores=1;server=NotTheServer";
try
{
odbcConnection.Open();
Console.WriteLine("Connection to database established");
}
catch (Exception exp)
{
Console.WriteLine(string.Format("Connection to database failed \n Error: {0}", exp.Message));
}
Console.ReadLine();
Kindly help to overcome this issue.
Thanks in advance.

Hi,
is it possible to make a C# form with a 30% opaque area in the middle while the rest of the form is 100% opaque?
Is there a simple way to make it via Paint override (Graphics/Brush/...)? I don't need anything fancy like individual component opacity - I draw everything manually.
Example:
http://lh3.ggpht.com/krukid/SLcqvNyDSSI/AAAAAAAAABs/odCi5lKLLck/opaq_gfx.PNG?imgmax=720[^] (Form1)
Thank you.

Dunno, but you can use a Panel to make a transparent area. What are you trying to do?
|
|
|
|

I'm thinking levels of opacity - not entirely transparent.
Full transparency is too easy to set, so I couldn't help to think something similar could be done about partial transparency, which seems to be set for whole forms only. That's a tease, I've seen various people ask about it every now and then, but no simple and/or definitive solution that I could dig up.
To be absolutely clear, what I am trying to do is displayed on a crudely forged image in the inital post - the link should still work  That is not a real app and that's the problem

Possible, but you would have to probably create your own control to do so.

Well, if I understand you right, the point of a custom control is still custom code in its Paint method, or did you mean something else?
If you have a thought on what to write to make it happen - please, I'd be grateful to hear it

Have you thought about possibly hosting a WPF control in your WinForms solution?

No, I have not - something new for me I will look into it, thanks!
