• Visual C# Two way Communication between exe and dll

  How could i acheive two way communication between the exe and my dll (without adding reference of each other in both ) thanks hi, thanx for ur quick response but i think i didn't make it clear enough. My problem is that I have a class residing in the dll which needs some data from the exe..(ie A function in the dll needs access to some classes defined in the exe) and also at the same time exe should have access to all public classes defind in the dll also. ...Show All

• Visual Studio 2008 (Pre-release) Zoom in/Zoom out in the DLinq designer?

  Hello! In the WebCast showing new things of the May DLinq CTP the guy showed zooming in/out of the DLinq designer. What should I do in order to zoom in/out of the designer Best regards, Henrik Dahl For zooming, how about the ubiquitous slider that we are starting to see in office/WPF/etc It would make sense with the future direction of smart clients.

• Game Technologies: DirectX, XNA, XACT, etc. Collision questions

  Hello. I'm currently trying to make a plane game. I'm working with the space divison right now, I was thinking of dividing all the triangles into cubes in an array. I have looked a long time for an equation to check collision between a cube and a triangle but the stuff I have found used very advanced mathematics to describe it. I've heard that cube and triangle collision could be accomplished with quite simple linear algreba I havn't read so much math due to my age but I know linear algreba quite good. My second problem should be quite easy, It's about how to check if a single point collides with a triangle. I think this can be done easily by using the bayCentric function but I just can't figure out how. I wonder if anyone could explain t ...Show All

• Visual Basic Publish question

  I think I asked this question in the wrong forum.....Maybe this is the right place... I created an application and published it. and it comes up on my Windows 'start'-'All Progams. Problem is, when look in Windows Explorer under "C:\Program Files" I can't see it. I right clicked on MyApplication under "All Programs" and it shows its under: C:\Documents and Settings\Administrator\Start Menu\Programs\MyApplicaton. When I navigate to that location all I see is a SHORTCUT. Where is my application... And I will (as usual, and strictly out of curiosity) ask the question "why do you want/need to see where the application was installed ". Best regards, Johan Stenberg ...Show All

• SQL Server Retrieving data types is slow

  Hello, i'm using SMO to retrieve information from various databases. It works well except for one thing. When I call the Column.DataType property to get the SQL type of a column it takes a very long tine. I have a few databases, each with some tables. There are about 75 columns I think. If I just browse all columns with SMO and write each name if it not a system one, it takes about 15 seconds (pretty much anyway). If I also retrieve the data type it takes about one minute. Any ideas why The server is a local one. Thanks ...Show All

• SQL Server trigger- get row number from inserted/deleted

  I need to add the row number or record number to the 'inserted' and 'deleted' tables in a trigger. Among other things, I have tried- SELECT 1 as rowId, i.* INTO #ins FROM inserted i if @@ROWCOUNT > 1 --if multiple rows, set row number begin SELECT @pkWhere = coalesce(@pkWhere + ' and ', ' where ') + PKF.colName + ' <= i.' + PKF.colName FROM #primaryKeyFields PKF set @strSQL = 'update #ins set rowId = (Select Count(*) From #ins i' + @pkWhere + ')' exec (@strSql) end -the above sets rowId for every record to the total instead of sequential. Keep in mind that this code is used to create a trigger for any table, hence I cannot specify any column names literally. This SHOULD be simple... right ...Show All

• Gadgets Detecting Gadget visibility / screen saver & power saving state

  Is there anyway to detect if a gadget is visible or covered by other applications or if the screen saver / display power saver is on I'm creating kind of a slide show gadget which will download images from an external server and it's wasting of server bandwidth to keep downloading the images when the gadget isn't shown so I need some ways to detect when the gadget should be suspended. You can detect if it's visible on the Sidebar, see my comments in this thread. You can't however tell if another application is covering it, the screen saver is on, or the display is in power save. This could however be done with an ActiveX COM. For the window overlap, you'd have to step through all the active window han ...Show All

  I have installed Winows Vista Ultimate (32-bit) on an HP Pavilion a1610n with the AMD Athlon 64 X2 4200 dual-core CPU. 2 GB RAM, 250 GB HDD. My wireless NIC is a Netgear wg311v3 PCI card, and my wireless router is a Netgear WPNT834 RangeMax 240 (802.11b/g). I am running DHCP and Shared WEP (128-bit) on the router.

In Vista network settings, the WLAN shows up as "Unidentified Network", Access is "Local Only", and the network keeps switching to Public, even if I manually switch it to Private. Obviously, I cannot surf the Internet since ...Show All
