• Visual Studio 2008 (Pre-release) How to set infinite activity timeout on netTcpBinding?

  hi, I have  a service that has an endpoint that uses netTcpBinding, the problem is that my proxy dies out after 10 minutes (inactivity timeout) I searched the forum and found some threads saying that the the element "reliableSession" should be set this way:  < reliableSession inactivityTimeout = " infinite "/>  but it didn't work (actually it ignored any value that I used) and the proxy still got into faulted state after 10 minutes, is there any other solution (I dont want to use "ping" to the server every X minutes) thanks in advance, ofer. Hi, thank you, it was very helpful, now I am  able to control the recieve timeout of the cl ...Show All

• SQL Server use exists in join

  Hello, Can i somehow use exists() function in JOIN ON clause for example SELECT * FROM Table1 INNER JOIN ON Table1.Col1 = Table2.Col1 AND EXISTS(SELECT * FROM Table2 WHERE Table2.Col2 = Table1.Col2) It doesn't work on my query. So, basically i want to do an inner join so that Table1 gets filtered. Then I make sure that every entry in the filtered Table1 has an existing related entry in Table2. i need to do exists because there could be more than one relation in Table2 for each entry in Table1, but i don't want multiple repetition of entries in the filtered Table1. (Not sure if i am making it clear!) I need distict selection, but i am adding NEWID() at the beginning of my query so distinct doesn't work for the rows. with my current query, i ...Show All

• SQL Server Will Debug.WriteLine work in a script component?

  I have traditionally thrown message boxes while developing SSIS packages and removing them when finished, but wish to move to something more appropriate. From my understanding, Debug.WriteLine is supposed to output to the console while debugging. In various places I'm calling System.Diagnostics.Debug.WriteLine("Stuff") but nothing comes up in the output console. Am I using this the wrong way Debug.WriteLine method has ConditionalAttribute("DEBUG") applied to it, the DEBUG macro is not defined when compiling the scripts, so this method does nothing. Use Darren's code instead. ...Show All

• Windows Forms Just-In-Time debugging Windows Forms

  Hello, In the MSDN documentation (How to: Enable Just-In-Time Debugging for Windows Forms) it is said: In addition, Windows Forms created with C++ must have the DebuggableAttribute set in a .config file or within their code.

• Visual C# Saving to DB after ReadXML - Update requires a valid InsertCommand when passed DataRow collection with new rows.

  1) I read data from a database, then save the data locally using WriteXML, 2) I Shutdown and restart the app ( to mimic real-world user behavior) 3) I Use ReadXML to re-populate my DataSource Now at this point, if I try to save my data back to the database, I get a "Update requires a valid InsertCommand when passed DataRow collection with new rows." It appears that all the rows that have been "ReadXML'd In" are considered "New". If I ReadXML and then AcceptChanges, I can make changes and save them back to the database. But I run into a problem if I save changes locally - in other words, make a change, WriteXML, then later ReadXML. If I accept changes, then those changes that got saved locally ...Show All

• Visual C# VS ComboBox missing display

  I while back I wrote a C# program using (among other things) a downdown combobox with items loaded using the .Items.AddRange() function. All works fine on my computer, but on other computers (without the VS Developer software installed), the dropdown box comes up blank. One can still select the different items through the mouse scrollwheel, so I know the data is being loaded, but the dropdown window is blank. Some of our computers have both .NET Ver 1.1 and 2.0 installed, others don't (mine specifically doesn't). The program was developed with VS .NET 2003 software. All the computers are running XP Pro, similiarily configured (though mine's the only one with the VS software), and all have the latest OS updates (I just checked). Any i ...Show All
