• Windows Forms How to find the window handle which window proc is subclassed

  I try to find the window handle of edit box in calculator. But failed.... I see from spy++, that the window proc of edit box is subclassed, i guess that may be the reason why I can't get the window handle. Because i can get all the other windows in calculator. My code is: [ DllImport ( "user32.dll" )] public static extern int FindWindow( string lpClassName, // class name string lpWindowName // window name ); [ DllImport ( "user32.dll" )] static extern int FindWindowEx( int hwndParent, int hwndChildAfter, string lpszClass, string lpszWindow); public static void Main() { int hwnd=0; int hwndChild=0; int hwndChild1 = 0; ...Show All

• Software Development for Windows Vista How likely are dropped frames in a simple graph?

  Greetings all. With regard to the ffdshow connection problem I posted about earlier, I figured it out. Apperently by default, ffdshow only connects to a few specific filters (DirectVobSub being one of them) that are known to support dynamic format changes. After disabling this option in the ffdshow options screen, my filter connects perfectly. Ugh... whoever coded that should be shot. Anyway, with that issue (finally) out the way, I face a new problem. In the program I'm writing, it would be REALLY beneficial to be able to seek via frame number, but obviously this is not an option for all media types, and I can't assume StartTime = FrameNum / FrameRate due to the joys of Variable Frame Rate media files. So a thought that occured to me was ...Show All

• SQL Server Array as procedure parameter

  I have a shift definition table with the columns: shift_id: shift's id shift_name: shift's name shift_number_of_day: shift's "position" on the day initial_hour: shift's initial hour final_hour: shift's final hour The shift definition depends on the company: company A may have 2 shifts, and company B may have 3 shifts, for example. I need to load a dimension table, dim_time, that should have a row for each hour of each day of a specific year. I would have alternate_time_key ... shift_name ... 1/1/2006 01:00:00 GraveYard 1/1/2006 02:00:00 GraveYard and so on, until it reaches the end of the year. So in my procedure to load the dimension table, I would have something like IF (@alternateTimeKeyHour ...Show All

• Windows Live Developer Forums Tile Overlay Refresh

  We are rendering overlay tiles in VE and we need a way to refresh our overlay tiles already present (loaded) in a VE session. There does not appear to be a way to do this. I have tried: DeleteLayer and DeleteTileSource and then re-add (AddTileSource and AddLayer)...we even tried deleting everything and reloading the map Map.LoadMap... Our overlay tiles just immediately re-appear instead of the source in GetTilePath getting called again. What can we do We resolved it...yes, it was a browser caching issue. Our GetTilePath points to a custom http handler to generate the tile images. All we had to do was convince the browser the same tile (xPos, yPos and zoomLevel) was actually a new tile by adding a superfulous parameter on the ...Show All

• SQL Server Update query runs very slow in SQL 2005 than SQL 2000

  We have upgraded our database server from SQL 2000 to SQL 2005. To migrate the DB I attached the mdf file in SQL 2005. After migration website loads quicker than earlier but records updation ( no of records are 20k) got slowdown. I have found that update query run very slow in SQL 2005 as compared to SQL 2000. Although other select query run very faster. Query is called from ASP (active server page) page. Changing of fill factor option from 0 to 70 also did not work.

• Visual C++ mangled name

  Is there any API to retrieve the address of a method (private/public) using the mangled name. the method is supposed to be a class member. we can know the mangled name from the .map file in VC++ 6.0 Please also suggest a method of using this in GCC. You can use the undname command line utility to un-mangle the name, if that helps. It's not clear to me whether you want to get the symbol address from another DLL, another static library or within your main project. ...Show All

• SQL Server Calling SSIS package from web service - Security issue

  I am trying to call a SSIS package from a web service hosted on the same machine as the package file is sitting. All that the package does is a simple Execute SQL task with one datasource connection. I have set impersonation as true. When I run the package from the web service on the virual port (through Visual studio IDE) it runs fine. http://localhost:4609/WebServiceRunSSIS/LaunchSSISPackageServiceCS.asmx In the above case I don't think impersonation means anything coz it runs successfully even when there is no impersonation set! I then run the same service (asmx page) from the browser after making it a web service on my machine http://localhost/WebServiceRunSSIS/LaunchSSISPackageServiceCS.asmx I get an error indicati ...Show All
