• Visual Studio 2008 (Pre-release) Videostream

  Hi all. Been looking around with the aim of writing an app that can both preview and stream webcam video, but appear to have fallen at the first hurdle. All the information I can find seems to be older, using either native calls or DirectShow to perform this, but I've been told that the framework now supports using a WebCam. Anyone got any information on how to use a webcam preview, and maybe how to go about streaming it over a network Thanks! to create a stream, you should use Windows MediaEncoder. you'll be able to choose the web cam as a source and a url as a target. plus it has an SDK, so you could automate part of it if necessary. ...Show All

• Windows Live Developer Forums Problems with custom tiles

  I am adding a custom tile using a static map image file on my pc and loading with AddTileSource & AddLayer. The file loads but not only is it not scaled or positioned correctly, but it also gets tiled across the whole background VE image The image is correctly georeferenced in the bounds clause and is based in the northern hemisphere - in the UK. I've tried bmp, png and gif formats - but same result. Is there a minimum bit map image size or lat/long precision issue that might cause this Are you using Map cruncher to produce the tiles I haven't had too many issues with layers, ther are others on the forum that have done quite a bit with them. Maybe if you have a link or some basic example of t ...Show All

• SQL Server Degenerate Dimension

  Experts: Pardon me for this basic question. A degenerate dimension as I understand does not have a parent dimension (pls correct me if I am wrong) in the fact table. In that case is it repeated in the fact table For example if i have the following fact table Productkey(FK) Customerkey(FK) Timekey(FK) TicketNumber All the first three (product,customer and Time) have dimensions while Ticketnumber has a orphan parent. In that case does its value get repeated in the fact table or is it usually a unique value Please explain. Thanks Ankith Hi Thomas: Thank you very much for a lucid and beatiful explanation with examples. Appreciate it. Best Regards Ankith ...Show All

• SQL Server SQL Server best practice with IIS

  Hi Everyone We are building a new site using ASP and SQL as the backend. Any idea where I can find some information about best practices to coonect the 2. I was thinking about IIS on a DMZ with port 80 only open and the SQL inside the internal network and open port 1443 between them. Any ideas will be welcomed. Thank you Oren Levy Hi bass_player Thanks for the prompt reply. How do you tell IIS to connect via a differnt port number I was thinking using ODBC for simplicity. Do I still leave it as 1443 on the IIS side and then redirect to a different port on the SQL side or vice versa. Thanks again. Oren ...Show All

• Visual Basic Can't open myscape.vb in Design Editor

  Alright, let me describe the problem I'm having: I was working on a program - a world switcher (yes, legal) for the game RuneScape, for my help site - and got quite far in. I had saved a few times along the road... And then Visual Basic crashed. No, the files were not corrupted, they had been saved several minutes before this. Anyway, I boot up Visual Basic (Express Edition) and click File -> Open File -> myscape.vb ^^ Can't get the design editor to come up. I see all the code that appears when you double-click an icon in the Design Editor... And yet... It doesn't load properly. In the same folder, I also have: myscape.Designer.vb (No changes made by me) myscape (.NET resource file [no changes made by me]) ...Show All

• SQL Server grouping rows by customer

  my source flat file has many rows per customer, but I need to transfer it to database with only one row per customer and accumulated sales (and probably do other calculations and lookups). I understand how to do stuff with derived columns, but how can I read source file first, calculate, group and then save to database As I understand, the script offers only processing row by row: Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer) Thanks Vlad I tried this, but I do not think it would help :-( it is more complicated calculation, than just grouping. I would rather do it in the script load into a Collection, loop, calculate, replace, substitute etc. and then save to databa ...Show All

• Windows Forms How to prevent ComboBox auto DropDown

  Hi, I'm writing a custom CheckedComboBox with a multiple item select future but when I select an item from the dropdown menu, the dropdown menu automatically closes. How can I keep it open to select more than one item thanks for any help. Hi Bluehunter, It looks like you are trying to make a custom combobox based on the System.Windows.Forms.ComboBox. Without access to the underlying code this might be difficult. Remember that a combobox basically presents a listbox after pressing on a button. So if you are making your own combobox, you can have your button present a listbox by your choice. Of course this can be a multiple select listbox. This way it's you that determines what happens on the listbox events. So yo ...Show All

• Visual C++ cin.rdbuf()->in_avail() always returning zero?

  Greetings, I am trying to determine if there is input on the console without blocking. I have built a simple console app in VC++ .NET1.1/MSDE 2003. I would think that after typing in some characters and a carriage return, it would return those characters one at a time. Instead, it doesn't appear that the in_avail() call ever returns anything but 0. Here is the code: #include "stdafx.h" #include <iostream> // just trying to have a nonblocking way to see if there is any input on the console // hmmm. how come this don't work int _tmain( int argc, _TCHAR* argv[]) { using namespace std; while ( true ) { if ( (cin.rdbuf( )->in_avail( )) > 0) { char c ...Show All
