• .NET Development Can't pass TableAdapter as argument

  Can't pass TableAdapter as argument In VB6 it was easy to build my own datalayer.  In vb.net 2003 it was difficult, not nearly as time saving as in vb6.  I was hoping vb.net 2005 would be easier. In many forms I fill table adapters, hardly a big surprise.  I was hoping to create procedures in a class that I could call from each form.  Unfortunately, I can pass a dataset, but I can't pass a TableAdapter.  When I try I get the message "Type 'TableAdapter' is not defined" Ah, Shucks! Is there a workaround dennist See the thread TableAdapters BaseClass. While you can change the b ...Show All

• Visual Studio Team System Can a Context variable be set from a Datasource?

  I want to run a user registration recorded webtest for each username stored in a database. I've:  - recorded such a test  - Added a datasource  - Added a context variable (sUsername)  - Set the Username page field to use the context variable But I cannot see how to set the context variable from the datasource The only thing that can be done in the context variable Properties window is set the value to static text. I tried using the same syntax that worked for setting the Username page field to the datasource value ... {{TestData1.Username.Username}} ... but that didn't work (it was treated as static text). If I can bind ...Show All

• .NET Development Networkstream & TCPClient - write does not throw IOException when server goes down.

  Hello all, I encountered a strange problem. I use a TCPClient to send messages to a TCP Server (by Network stream's Write function) when the server is connected it all goes well, but when the server closes the connection I get IOException only on my second write! - the first write method is called as nothing had happened. I tried to give my TCPClient true on NoDelay and also fixed the SendBufferSize of the TCPClient to be exactly as my message size (163 bytes). nothing helped. please advise! thanks ahead hi, what about reading from the server when the server close connection itsends ...Show All

• .NET Development Using HttpWebRequest to HTTP POST using Credentials - Underlying connection closed

  I am hoping someone out there knows why this is happening: I am writing an application that is going to be making many requests to authenticated web pages - by authenticated, I mean using HTTP Auth (you know, that grey box that pops up asking you for a username and password). I have been using WebClient for this because I don't need much more functionality than simply reading particular pages or posting to a few of them.  However, I am willing (and have recoded my app) using HttpWebRequest, with the same problem. My problem is this: I can do GET requests just fine (DownloadData using WebClient or just reading the stream usin ...Show All

  Hi everyone, I have a ListObject in Excel bound to a datatable which has >100K rows in it and I need to page through it. I am currently calling back to the DB everytime I need to get another page; but I really would rather page throught the dataset (this need to be a disconnected system). Any suggestions on how to do this are welcome. Thanks, Blair Hi Blair, You can read the entire data into a dataset at the beginning. Then, you can create a BindingSource that uses this dataset as it's data source. Set the Filter on the bindingsource so that the requisite page of records is filtered in. B ...Show All
