• Windows Forms showing blank instead of value in datagrid

  HI, i'm binding SQL table into datagrid via dataset and datatable. To avoid null problem, I've used '-1' as a default value of columns in sql table. All columns are integer datatype. When i bind this table into a grid, '-1' is also shown along with other valid datas. I donot have to show '-1' on grid.Instead of "-1" ,i need to leave it as blank. i tried to assign " ". It's violating int datatype rule. Is it possible to show blank instead of "-1" If so, How Thanks! you should probably remove the default and update to null where -1. until then you can select ...Show All

• .NET Development DataSet.AcceptChanges() doesn't accept all the changes!

  Hi, When I do a dataset.AcceptChanges there's always one table that I must additionally accept the changes befora all my changes are accepted. dataset.AcceptChanges() dataset.tableX.AcceptChanges() There are no errors in the dataset. Does anybody know why Thanks, Filip I understand that after invoking DataSet.AcceptChanges90 you are still seeing atleast 1 table which has 1 or more changes. We tried to reproduce this at our end but were unable to do so.

• .NET Development ASP.NET 2.0 Advocacy

  I am looking for some resources and/or compelling arguments I may use to help "sell" ASP.NET 2.0 over PHP 5 internally. We have a PHP based user-facing control panel application, written in PHP 4.3. Given the rich interaction model we are designing, I simply don’t think PHP 4.3 or even 5.0 is up to the challenge. Unfortunately, I work in a Microsoft-hostile environment, and I’ll need strong ammunition to prove myself right, especially if I’m going to recommend we switch platforms, which of course involves spending money. My requirements include “brandability”, which I know I can easily satisfy using dynamic master pages in ASP.NET 2.0. T ...Show All

• Visual Studio 2008 (Pre-release) Frame and UserControls will not expand to fit available space.

  When I try to load modular content with Frame or UserControl, Frame and UserControl elements will not expand to fit available space. The size of these elements remains fixed (current fixed to MinWidth and MinHeight. ScrollView also suffers from the same problem. I'm wondering wether this is a problem with something in my code or whether it's a problem with CTP code,. Is this a known issue with the Feb CTP or am I doing something wrong If it's a known issue, I'll live with it for a while. If it's not, I'll dig further. I'm building a pretty complex UI, and the inability to modularize UI compontents due to this problem is making ...Show All

• .NET Development Thread.Abort fixed for finally blocks?

  In .NET Framework 1.0 & 1.1, calling Thread.Abort on another thread could abort that thread while executing the "finally" part of a try/catch/finally block. That was rather nasty because it could lead to criticial resources not being released by the aborted thread. Now I see in the July CTP docs that this situation is documented as a possibility for 1.0 & 1.1 only. May be assume that this has been fixed in 2.0, and that all finally blocks will properly execute in the aborted thread, no matter when the ThreadAbortException happens Another question: ThreadAbortException can still happen in a catch block and abort the current exception ...Show All
