Re: [wxhaskell-users] wxHaskell 0.10.3: problems in Windows XP
Hi, I start this when i read in http://wxhaskell.sourceforge.net/download.html that concerning binaries for version 0.10.3: "All packages have ODBC support (but not OpenGL)." But at least the windows binary (as stated by shelarcy) and the wxhaskell-bin-powerpc-mac2.6.4-ghc6.8.2-0.10.3-0.dmg have opengl enabled. I tested those two packages my self with code using opengl.

Hi, The Microsoft Visual C++ 2005 SP1 Redistributable Package solves the problem. Just great! If anyone with access to wxHaskell webpage at sourceforge could add a note in downloads page about this issue, could avoid others to have this problem. Something like You may need to install Microsoft Visual C++ 2005 SP1 Redistributable Package (http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14 -984d-389c36f85647&DisplayLang=en) or else you may see the error message "The applicattion failed to initialize properly (0xc0150002).

Re: [wxhaskell-users] wxHaskell 0.10.3: problems in Windows XP
Hi again, After several unsuccesseful tries, and some googling, I found out many complains of people seeing the message "The applicattion failed to initialize properly (0xc0150002). Click OK to terminate the application." when they run their executables out of the devellopment machine. The error also seems to be often related with: * DXUT - related with images and DirectX SDK - (see http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1048802&SiteID=1) * MS Office (see http://support.microsoft.com/search/default.aspx?mode=r&catalog=LCID%3d1033&1033comm=1&spid=global&query=0xc0150002 ) Some pratical, to find a solutions is pointed in http://www.tech-archive.net/Archive/VC/microsoft.public.vc.mfc/2006-09/msg02020.html: "To see dependent DLLs, open your application with the dependency viewer (depends.exe)." Can you please take a look on this and see if everything needed is going into the DLL? In the meanwhile, I also found that the 0.10.3 binaries loose the opengl support compared with 0.9.4 as pointed in http://wxhaskell.sourceforge.net/download.html. Is there some reason for this? In my specific case that will also be a problem. But the 0xc0150002 is not related to this since the simple (and not opengl related) HelloWorld.exe continues failling in my machine. Since I found one machine that runs the code and one that doesn't, I comparing the software installed on them.

Im also having a problem (the same, I guess!) with the RC2 binary package for Mac: when linking there are missing libraries. After a closer look, the linker asks for files like /usr/local/lib/libwx_base_carbonu_xml-2.6.0.dylib /usr/local/lib/libwx_macu_SOMETHING-2.6.0.dylib But the available files are /usr/local/lib/libwx_base_carbon_xml-2.6.0.dylib /usr/local/lib/libwx_mac_SOMETHING-2.6.0.dylib It seems there is an extra 'u' in the names (see carbonu and macu). Creating symbolic links solve the problem for most of the libraries. At the moment I'm trying to figure out how to solve a few of them; probably more options for configure wxMac.

[wxhaskell-users] Stop do not stop; not multi-threaded?
Hi Im running a program with a graphical interface in wxHaskell. My program have one button that starts a sometimes very long computation that even could get cyclic in some cases. I created a Stop button that when pressed changes the State of the application (type State = Var MyRecordType from http://wxhaskell.sourceforge.net/doc/Graphics.UI.WX.Types.html#t%3AVar ). Then my very long computation, before calling the recursive call, checks if the State is saying to continue or stop. In theory this seems the solution but when I tested it I find out that it doesnt. The very long computation gets the attention of the processor and blocks the graphical interface; clicking the Stop button dont fire the actions. Im not sure but is this running sequencially? Which ways have I to overcome this block? Best Miguel - Using Tomcat but need to do more? Need to support web services, security?
