Hi all,

I would like to know is it possible to switch between mulitple profiles within the same application?

I have a problem that once I logon a profile, I find no means to switch to another profile. I have tried to use logoff method but it fails, it still stays with the original profile.

Owner drawn text box

Hello

I'd like to have a text box that I can selectively put a little red triangle in the top right corner of, pretty much in the same way excel does when you have comments on a cell. I had a look at handling the Paint event for the text box but it doesn't seem to be getting fired. Is there something more than assigning my own handler function to the paint event delegate to achieve this? I haven't inherited from the text box control, could this be the problem?

BTW If it's not obvious I'm pretty new to .NET Smile | :)

Cheers

David

You may need to set the textboxes ControlStyles.UserPaint style bit (Texbox1.SetStyle( ControlStyles.UserPaint)) in order for the paint event to fire.

If you plan on having several of these, it might be worthwhile to create your own by subclassing (inheriting from) it, so that you dont have to repeat a lot of code.

Hello Rob

Thank you for your answer. I've been looking for a property or something, and now it looks like I've found it...with your help of course Smile | :)

The main reason I didn't want to inherit from the text box is that I want to implement this feature as a kind of decorator that I can use on a selection of controls. I'm creating a control manager that will create the controls dynamically, and a "state" manager that will manage standardised sets of functionality based on what the user is doing e.g double click on a text box to display a window containing a list of values. Having the red triangle...or any other visual cue, will be the indicator to the user that they can double click to get the window.

I'm not adverse to inheriting controls, but if possible, I'd rather stick to standard controls and manipulate them wherever possible. Do you think I'm approaching this in the right way?

Thanks

David

How are you connecting to the Oracle Database? ODBC? Microsoft Oracle Data Provider? Oracle's Data Provider?

What version of Oracle client is installed on the machine?

This article[^] has example code for connecting to Oracle 9.

I've only ever had problems in the past when the Oracle 9 client wasn't correctly installed on the machine or the TNS names had got screwed up.

You seem to be missing the point. What version of the Oracle CLIENT is installed on your machine? It would appear that you don't have the proper Oracle Client installed on the machine to connect to the server.

Unless you have the Oracle 9i client software installed, then you probably can't.

i think i had the same problem a time ago
you need to install Oracle Data Provider ( i think you can download 4 free)
and use the objects in the Oracle.DataAccess namespace ( firs add the dll to the project )

Rational Rose (not XDE) and C#

I am wondering how people manage the transfer of design in Rational Rose to Visual Studio and C# (and vice versa). I know the Rational has XDE which allows round trip development - this is not an option for me. I am using Rose Pro ver 8.3.

I want to be able create code in VS using C# and take the class diagram over to Rose. And also create a model in Rose and transfer that to VS as easily as possible.

I could retype all the information between the two but this seems a long winded way of doing it. Does anyone have suggestions on how to achieve this with greater ease?

Thanks,
Liam

concatenate text into a .def file

Hi I want to update a .def file from different window forms .I want to concatenate some text in the .def file and dont want to lose already available text in the .def file. Is there a option to directly concatenate into a file or do I need to store all the information in a class and then write it.

Thanks and Regards
KR

When creating your StreamWriter, use a constructor[^] which takes a boolean 'append' parameter. Specify 'true' for this parameter.

If you want to append this text to the very end of the file, then follow what Mike said. Otherwise, you'll have to read the file in, write the beginning of the file back out until you reach the point where you want to append your text, append your text, then continue writing out the rest of the .def file.

Customize errors

21-Jul-05 23:23

Hello All,

I want to customize error messages returned by exceptions. For example I want to customize the following error

"Error [42000] [Microsoft] [Odbc SQL Server Driver] [SQL Server] could not find stored procedure"

I know I can restrict exception.message and throw a customized error, but how I will know whether the error is because of this..or something else...

Could anyone please let me know how can I do that in C#...

Thanks

Looney

hi
you have to write two catch Block to handle ODBC and other type of exception..

try<br />
{<br />
//..Code that generate error<br />
}<br />
catch(OdbcException odbc_ex)<br />
{<br />
for (int i=0; i < myException.Errors.Count; i++)<br />
{<br />
if (odbc_ex.Errors[i].NativeError == 42000)<br />
Console.WriteLine("Procedure not found...");<br />
else<br />
Console.WriteLine(odbc_ex.Errors[i].Message);<br />
}<br />
}<br />
catch(Exception ex)<br />
{<br />
//..<br />
}
