Hi there!
I would like to know if it's possible, and if so, how can I add a reference to a library programatically in the .net framework.
The idea is to have somethin like we had with the CreateObject("library_name") in the VB6 days.
Any help is welcome!
Thanks in advance for your time.

There is a complete library in .Net called Reflection that allows you to query a type or create an instance without referencing the assembly on compile.
I would suggest you to go through the Reflection namespace and esp Assembly class. (http://msdn.microsoft.com/en-us/library/system.reflection.aspx[^]

I have been tasked with researching third party object-relational mapping and RAD frameworks for .NET
Our organization is just starting a long term migration from VFP to C# / .NET and wants to kick start this process by employing a third - party ORM framework.
I have not used any third party frameworks for ORM in .NET yet and don't want to get painted into a corner at this early stage.
One of the frameworks we are reviewing is called Mere Mortals.NET by Oak Leaf Enterprises Solution Design.
I have also heard of another product called IronBlade Dev Force.
Anybody had experience with these products or third-party ORM frameworks in general.

I know Pete has already mentioned about cross-posting, so I'm just adding a pointer to the other message here. That way, if someone else goes to answer or look for an answer they know where to go.

Im trying to make a custom user control (web control or ascx control) with my own custom elements but I can't get it to work. It is easy to add custom attributes (like DataTableName in example below) to a custom contol. The following code will demonstrate what I mean by custom element.
<custCtrl:custTable ID="MyCustTable" runat="server" DataTableName="Groups">
<custCtrl:Columns>
<custCtrl:custColumn ColumnName="Column1"><custCtrl:custColumn>
<custCtrl:custColumn ColumnName="Column2"><custCtrl:custColumn>
.
.
.
<custCtrl:custColumn ColumnName="Columnx><custCtrl:custColumn>
</custCtrl:Columns>
</custCtrl:custTable>
I've searched for articles like this but I couldn't find any. any help will be appreciated.
Thanks

Hi,
Do you set the hard code size? I mean how do you set the maximum size?
Cheers

Hi,
Take a look at this article on msdn about automatic scaling of Windows forms.
http://msdn.microsoft.com/en-us/library/ms229605(VS.80).aspx[^]
Also I'm not sure if you have understood your customer's problem. Switch one of your monitors to 800x600 resolution, run your app and I think all will become clear.

You can use a combination of tablelayout, flowlayout, form and controls' dock property to make all the controls scale nicely (thought not perfectly).

Hello
I am using multicast delegate as follows, but the effect in the server is undesirable:
Thing.OnEvent1 += new IThingEvents_OnEvent1EventHandler(OnEvent1);
Thing.OnEvent2 += new IThingEvents_OnEvent2EventHandler(OnEvent2);
Thing.OnEvent3 += new IThingEvents_OnEvent3EventHandler(OnEvent3);
The problem is that the (C++ COM) server it thinks it has all the connections for each event.
So in the below example it trys to send the event 3 times. Apart from the unecessary processing, I am worried it is making the inter-process call each time (the incorrect calls are being thrown away on the client side somewhere).
HRESULT Fire_OnOrderCancel(lots of params)
{
HRESULT hr = S_OK;
T * pThis = static_cast(this);
int cConnections = m_vec.GetSize();
for (int iConnection = 0; iConnection < cConnections; iConnection++)
{
pThis->Lock();
CComPtr punkConnection = m_vec.GetAt(iConnection);
pThis->Unlock();
IDispatch * pConnection = static_cast(punkConnection.p);
if (pConnection)
{
CComVariant avarParams[20];
//set avarParams
CComVariant varResult;
DISPPARAMS params = { avarParams, NULL, 9, 0 };
hr = pConnection->Invoke(1, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_METHOD, ¶ms, &varResult, NULL, NULL);
}
}
return hr;
}
What c#/.net thing do I need to use to get the desired behaviour, namely events to be fired once and the c# client to do the correct delegation?
Many Thanks

Hi
I need to take the user session ID number (maybe is called session token or SID) in my windows VB.Net application, it is a unique number per session, same user different sessions should have different numbers. I tried a lot of ways (almost everything from win32) without success....
|
|
|
|

This sounds like what you need:
Process.GetCurrentProcess.SessionId
Good luck!
|
|
|

String ID=Session["ID"].ToString();

hi there,
I'm trying to connect to oracle DB from .net web service (c#), but can't connect. Please help if someone has any insight.
Here's what I'm doing:
Web service.WebMethod code:
---start
[WebMethod]
public string RunInterface1(string ConnectionString, string strQuery)
{
try
{
string connectionString = ConnectionString.ToString();
using (OracleConnection connection = new OracleConnection())
{
connection.ConnectionString = connectionString;
connection.Open();
OracleCommand command = connection.CreateCommand();
string sql = strQuery.ToString();
command.CommandText = sql;
OracleDataReader reader = command.ExecuteReader();
return "Success";
}
}
catch (Exception ex)
{
return ex.ToString();
}
}
--- end
Note: connection string and strQuery is passed as input parameters
Problem:
When I run it, I get following error:
Cannot access NLS data files or invalid environment specified
Thread:
System.Data.OracleClient.OracleException: ORA-12705: Cannot access NLS data files or invalid environment specified at System.Data.OracleClient.OracleException.Check(OciErrorHandle errorHandle, Int32 rc) at System.Data.OracleClient.OracleInternalConnection.OpenOnLocalTransaction(String userName, String password, String serverName, Boolean integratedSecurity, Boolean unicode, Boolean omitOracleConnectionName) at System.Data.OracleClient.OracleInternalConnection..ctor(OracleConnectionString connectionOptions) at System.Data.OracleClient.OracleConnectionFactory.CreateConnection(DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection(DbConnection owningConnection, DbConnectionPool pool, DbConnectionOptions options) at System.Data.ProviderBase.DbConnectionPool.CreateObject(DbConnection owningObject) at System.Data.ProviderBase.DbConnectionPool.UserCreateRequest(DbConnection owningObject) at System.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.OracleClient.OracleConnection.Open() at Service.RunInterface1(String ConnectionString, String strQuery) in c:\Apps\test\testws\App_Code\Service.cs:line
What I have tried so far:
- Remove/rename registry entry for NLS_LANG - No luck, no matter what I do with it. Tried different value setup also.
- Tried with 3 versions of Oracle client: 8, 92 and 10. (current ver is 10)
- Cleanup registry - No issues
- I'm able to connect to same oracle instance from PL/SQL adn SQL plus
- I have created a windows form application - same code as you see above, and it works flawlessly there. Only web service fails. God knows why!!!
And yes, I have TNSnames.ora copied all over in the system: bin folder, wwwroot folder, app folder, oracle\...\network\admin folder... didn't leave any place.
for God sake, please help !!!

Is this running via ASP.NET? Or some other user with limited permissions? Or perhaps not on the Local Computer Zone?
|
|
|
|
|
both applications running on the local machine under a administrator account
|
|
|
|
|
It seems you are running it as a service?
Try running it without it perhaps. Not sure I can help any more 
Try Googling for something similar.
