Hello, I dont understand whats going on with my DB2 connector. I used to
have the code in a class that worked fine. But when I tried to use it in a
webservice I get this error: System.InvalidOperationException:
ExecuteReader: Connection property has not been initialized.
1) I create and open a new OleDbConnection
adoConn adoConn = new adoConn();
adoConn.Run("INTRANET");
2) I execute the query
OleDbDataReader myReader = adoConn.dbSQLSelect("Select * from USERS");
ERROR
Line 47: myReader = myCommand.ExecuteReader();
What might be the problem?

My first C# development at work needs to connect to a unix box and transfer files (both directions) using SSH (secure shell) and SCP (secure copy). Can anyone recommend a product/component/code to do this? I've come across Putty and SSHActiveX etc but I'd like a .NET solution if at all possible. Thanks.

I know I can use the TAB key to move from TextBox to TextBox; can I also use the Enter Key? I have 300+ TextBoxes and I want the Enter key to move vertically and the Tab key to move horizontally, any thoughts?

Hi Mike. There may be a much easier way, but the only way I can see is to handle the KeyPress event for your textboxes. This link from MSDN[^] shows an example of capturing the [Enter] key; you could then execute SetFocus() on the appropriate text box.

Hi. I'm looking for a solution to this question:
so, I'd like to disassemble a strong named assembly,
edit its IL a little and compile it again with
different key pair. however, i want to keep the
original public key. Is that possible? I think so,
but don't know the right steps. Please help me.
Thank you in advance,
Stan

yep, i'd read an article to work out re-signing, but the public key changes, and what i need, is not changing the public key

I'm hesitating on changing Platform from VS6 to VS.Net. Would you
please to tell me what's the prospect of MMC in Microsoft .NET plan?
There's an MMC Snap-in designer for VB 6.0 ,and is there a designer for
VB.NET? Does Microsoft have anything substitute for MMC in .NET
platform or something in the future?

Hello,
I'm building a .net component (let's call it Alpha) for use in a Win Form application. There is also a second component type called Beta. Alpha has a property called Betas that is a collection of Beta components. This is similar to the TabControl and TabPage where TabControl has a TabPages collection.
My question is, does anyone know how to cause all Beta collection items created at design time to be deleted when an Alpha component is deleted?
Thanks in advance

hello developer world,
I've to read a xml file with encoding 'iso-8859-1' with the XmlTextReader class. But I get the following XmlException:
The System does not support the 'iso-8859-1' encoding. I can't use the utf-8 enconding, because there are special characters to read.
Can anybody tell me how can I solve this problem?
I'll be very pleased.
Reinaldo.

What about UTF-16? IIRC, Pocket PC using 16bit-Unicode characters as the native character-set.

Hi all,
I want to know what methods in my .NET application "eat" most of CPU time. May be someone knows if CLR provides such information? Or the other way?

I switched from Visual C++ 6 to a C# .NET solution. In my original VC 6 project I was linking a .lib file to my code. The .lib was providing me some functions to a CORBA orb.
This .lib file doesn't seem to be working with my new .NET project. Does anyone know if you can use libraries coded in legacy VC++ 6 with the new .net framework or do I have to rewrite the libraries in C# .net as well?
Thanks,
Zahid

Zahid

You should be able to, but I don't know how.

I have many VC 6 libraries that just work in both the 2002 and 2003 Visual Studios. Now, you didn't mention, but your still compiling C++ code, right? The C# or VB.NET stuff won't be able to use those libs.
If you still can't get the libs to work, how about listing what the errors are? Perhaps something might need some tweaking.

Some header includes are now officially redundant in 2003 so Microsoft is more 'ANSI compatible' and portable. If these lib headers include some now redundant libraries, you will have problems. A colleague of mine had linker errors. If these circumstaces sound familiar then changing your projects build order is needed to remove them.

There seems to be a lot of headaches that become apparent on this message board when it comes to topics such as "enforcing database constraints" or "enforcing complex business rules in the database" or just plain trying to automate the simple tasks that it seems we developers do all the time. From nudging controls around on a form, to getting 30-50 forms created for a simple application. These mundane tasks take a lot of time away from what you really want to do - program.
I work for a company called Dataphor with a new development tool that not only automates the application development process, but also allows for a declarative approach to enforcement of complex business rules, constraint enforcement, etc.
The product I am speaking of is Dataphor - an automated application environment. By combining the power of a businews rules engine, the automation of a meta-data repository, and the flexibility of a RAD environment, Dataphor provides an unprecendented level of prductivity and maintainability.
Dataphor is a product of Alphora and is built on the .NET Framework in C#. More information may be found at alphora.com.
