• Visual C# PVInvoke error..

  "A call to PInvoke function 'ResThemer!SPINE_RES.Resourcer::EnumResourceTypesA' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature." This is the error I get when using 'EnumResourceTypes' in kernel32.dll. The call uses a delegate the acts on a callback of a user-defined function, in this case I call 'EnumResourceNames' from within it. I have been trying for two days to translate what the MSDN Library shows you in Cpp but to no avail. Any help on how to do this would be great.

• Windows Live Developer Forums How to get the VEPolyline information from the GetRoute()

  I am trying to get the VEPolyline information from the GetRoute. I don't find any thing related to this in SDK.My problem is I am trying to create an application to map the multiple routes. Currently we can create the only one route. I tried to get the each segment and LatLong object. You know if you try to draw line between them, you get a straight line! This is a feature many people (including me) have shown interest in but it isn't available yet. I had hacked the API at one point to capture all the point in the polyline for each route but it was clunky and unreliable. I'm still waiting for MS to provide multiple route functionality. ...Show All

• Visual Studio Express Editions How to create a single executeable?

Any ideas on how to create a simple single executeable Thanks in advance... Ashley what do you mean by single executable an application is pretty much a single executable app. if you are talking about the .NET Framework then no, there is no other way of running your .NET Developed application on a computer that does not have .NET Framework installed (the correct version). How would it access the .NET components to run your app its like a car - you are telling the shell of the car to just run without the ...Show All

• SQL Server Out of memory while querying causes wrong data to be returned

  Running AS 2000, SP4. A couple of times while querying a cube, one member has got the wrong data displayad (the value are to low). No matter if I reload the query afterwards, restarting the query application etc, the same faulty value still gets displayed for that member. After I restart analysis services the value is correct again. No other changes, exact the same query etc. While analysing the event viewer I see that analysises services has run out of memory before this strange behaviour (MSSQLServerOLAPService - "The server is out of memory"). Could this out-of-memory error has caused the wrong value to be returned, and the somehow the value has got cached on the analysis server so it's not fixed until the server has restarte ...Show All
