• .NET Development How do I retrieve new primary keys after inserts?

  Hi, I am relatively new at ADO 2.0, so please forgive the simple question. I add some rows to my datatable in memory, but without trying to assign primary keys in the rowid column. In the datatable, the rowid column is null for all the new rows that I add. Eventually, I use a dataAdapter.Update(table) call to update the database, which is successfully updated. But now the problem arises... I don't know how---for those new rows that were just inserted into the database---to read the new primary keys (generated by the database) back into the correct rows in my datatable (using a dataAdaper if possible, using plain SQL if not). I don't wa ...Show All

• Visual C# My code editor

  I'm trying to make a html/javascript/css... CODE editor. I tried to use rtf control, but it is too poor and hard-to-customize (scroll bars bugs and too much...). I want know if there are a better option to do it. Some samples Thanks a lot! www.codeproject.com has a syntax highlighting text box in c++, I used it in a Python IDE years and years ago. That's probably a good place to look for a C# alternative, but I don't know for sure that there is one. ...Show All

• .NET Development Performance question

  Lets say I need to retrieve around 3000 records from a server database (LAN). Now, on the form there are some record filtering options. My question is: do I fetch all the records at once, and filter data based on user selection, or should I pull data from database whenever the user changes filtering options And another question: since these are read-only data, then the choice for returning data should be datareader. But if I choose the first option (fetch all data at once), then how can I filter data, since when I retrieve data with datareader, I always put data in arraylist, and as far as I know, arraylist data cant be filtered Thank ...Show All

• Visual C# c# colordialog custom colors save

  Hello, Is there some way to save and restore the custom colors in a colorDialog in a Windows Forms project When I look in the ApplicationSettings's PropertyBinding pop-up for the colorDialog, those custom colors are not there. Thanks. The ColorDialog class exposes a property called CustomColors which is an array of integers that represent the colors in question in an ARGB format. Worst case you could save these values manually after use of the ColorDialog and then reload them later. ...Show All

• Visual J# java (J2EE 1.4) convert to J#

  Hi, I want to convert my application in java (J2EE 1.4) to J# with minimum changes. Where can I get the script Thank's Alexei (I have tryed JLCA 2.0, 3.0 and it gives me about 100,000 errors becouse it convert to C#. I don't have a time for working on errors. I read that Java can be converted to J# with minimum errors.) Generally my experience doing this always leads me to running the J2EE code under Object Web or JBoss's free J2EE server and building either a webservice or RMI invocation layer to bridge the .NET code. This does assume that you have a good MVC design where you can easily seperate the backend J2EE components from t ...Show All
