• Smart Device Development Emulator does not launch Activesync

  I have no problem cradling the Windows Mobile Pocket PC 5.0 Emulator, but when have done so, ActiveSync (4.2.0) does not launch. It wakes up fine when I plug a real device into the USB port.

• Visual Studio 2008 (Pre-release) Starting new project => should I use WPF or Windows Forms?

  I am just about to start with developing new standalone application that I expect to be ready in year and half. It should replace existing old version written in C++ using MFC. My first idea and reason to start was to improve mainly UI and to use C# .Net 2.0 and Windows Forms to achieve this. But now I found that there is something like WPF in .Net 3.0 and it seems like soon future. So I am really confused. Do you expect .Net 3.0 to be RTM sooner then in one year Is current state (June CTP) ready to start application development that would make sense or is it just for “playing around” and API changes in future will be too big I would like to use new technology but I don’t want to loose all my hair. ...Show All

• .NET Development Generic performance... benefit?

  Hi, in every article about generics is written that they improve performance because no boxing, etc. occurs. So I wrote this simple test code and was astonished that the non generic part actually performs a couple milliseconds faster than the generic part About 59.8 seconds for the generic and 59.1 seconds for the non generic (avg. of 10 runs). Am I missing something here [code] using System; using System.Collections.Generic; using System.Text; using System.Xml; using System.Collections; namespace ConsoleApplication6 { class Program { static void Main(string[] args) { string s = ""; Test<string> test = new Test<string>("hi"); DateTime start = DateTime.Now; for (int j = 0; j < 1000000; j++) { foreac ...Show All

• Windows Forms [solved] DataGridView.Sort explodes after modifying/adding row(s)...

  I am creating a little app that has a DataGridView to keep track of tasks. In the DataGridView I have several columns - an id (a textbox column set with the ValueType of Type.GetType("System.Int32")), a priority, an image column (representing the priority with an image), and a few other text, date, and checkbox columns. When I first load my application, I read in the data from a DataTable in a DataSet, and create a new row in the DataGridView for each row in the DataSet. This allows me to select the right image for the image column based on the value of the Priority column. When the application shuts down, it does something similar - for each DataGridViewRow in the DataGridView, it extracts the data that needs to be written to the disk, ...Show All

• Visual C++ Problems with SendInput(): clicking somewhere without moving the cursor

  I'm having problems with emulating a click without moving the mouse cursor. I call SendInput() with the proper parameters, but the click only seems to be executed if I first move the mouse cursor to the click point. Is there any way to send a click message to an arbitrary point and have Windows execute it, or is clicking hardwired to the mouse cursor position Maybe you have to add an additional item to your SendInput parameter which will simulate the mouse movement to the old cursor position after performing the click ...Show All
