• Visual C++ Compiling fftw - what flags should I use for best performance?

  Greetings, I have compiled the fftw fft package from www.fftw.org  using the Visual C++ 2005 Express Edition beta 2 but I can`t seem to find a good choice of flags for optimizing the code. As I run the benchmark code that comes with the package I get slower performance with msvc than if I compile with gcc 3.3.3 under cygwin which seems strange because I usually see the opposite behavior. Has anyone else tried to compile this package with the current beta and have any suggestions for choosing optimization flags thanks in advance, Carlos Thanks for digging more into this. Since you sre still seeing a slow ...Show All

• Architecture Spcification of web services you need from third-party company

  I want third-party company to implement bunch of web services. I wonder what it is the best way to specify them. I can create wsdl for them, is it ok Interoperability is very important because services will run on non-windows machine and clients will run on windows boxes. thanks in advance for any info Pawel, Are you saying that you want them to use web services that you have implemented We have toyed with this question ourselves. There are, basically, two avenues of approach: Deploy your wsdl in a public or client-accessible arena, point them to it, and wish them luck. Or, what we have considered, and begun doing, is creat ...Show All

• SQL Server MDB to SDF

  Hello, everyone. I am a new developer of .NET CF. Currently, I have a project that needs transferring tables from a existing Access database to SQL Server 2005 Mobile database. Does anybody know how to do it Thanks in advance.     Are you talking about MS Access Database or MS Pocket Access Database. In any case, we dont have any tools for doing that automatically. However, you can always open two cursors (Datasets) against two DBs and transfer the data one row by row. I know its a slow operation but it is all design time. Thanks, Laxmi Narsimha Rao ORUGANTI, MSFT, SQL Mobile ...Show All

• SQL Server Help with "flattening" a table

  Hi All, I have a database that stores some data from two questionnaires. Table One has been created in a fairly straightforward manner. It has the following fields: ID, variable1, variable2, variable3, ..., variablen Table Two is a bit more complicated. I'm guessing whoever created it wanted to do things a bit more "efficiently" and it has the following fields. ID, variable, response. If I wanted to, say, extract variables 2, 3 and 5 from Table One I could write: SELECT ID, variable2, variable3, variable 5 FROM TableOne I don't know how to do a similar thing with Table 2 using only one statement. ie, I can ...Show All

  Hello, After reading the documentation and some online articles about UITypeEditors, TypeConverters etc., I didn't find a way to use a masked edit box for the editing of a property, or to forbid the input for a property and allow only the custom drop-down (which I have already constructed and don't need any instructions about this).

• SQL Server Delete subreport at runtime?

  Is it possible to delete a subreport from a main form at run time I am trying to find a work around for the inability to conditionaly format a page break. I have a main form that has 10 subforms. Some of the subforms won't have any data (depending on the parameter values). When I export the main form to excel each subform needs to be in it's own excel tab. Obviously, I don't want a tab if there is no data.
