windows - qt in windows7 environment -

-

i having problem running example qt uses win32 libraries. when compile don't errors when run not able open application (.exe) file in windows 7. when compile example in windowsxp works fine. can let me know whether need change .pro file in order worked under windows 7?
here .pro file:

# ------------------------------------------------- # project created qtcreator 2010-04-16t11:45:43 # ------------------------------------------------- qt += network qt += xml qt += opengl target = application template = app sources += main.cpp \     mainwindow.cpp \     tools.cpp \     objects.cpp headers += mainwindow.h \         tools.h\         objects.h unix {      objects_dir = .obj     moc_dir = .moc }  # unix installation isempty(prefix):prefix = /usr/local unix {      headers.path = $$prefix/include/zip     headers.files = $$headers     target.path = $$prefix/lib     installs += headers \         target } !mac:x11:libs += -ldns_sd win32:libs += -ldnssd libpath = c:/temp/mdnsresponder-107.6/mdnswindows/dll/debug includepath += c:/temp/mdnsresponder-107.6/mdnsshared

you can use dependency walker find out qt dlls needed , copy them same folder .exe.

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
