runtime error, the procedure entry point problem

[billconan]

hello guys,

my code compiles. but when i run my code, i get the following error.

the procedure entry point ?toAscii@QChar@@QBEDXZ could not be located in the dynamic link library QtCored4.dll

i don't know where the problem is, could you please help to fix that.

i'm using qt4.4 under winxp

Did u include the headers properly ??
probably QString or QChar ?

Sounds like you compile against one Qt version (newer) but run with a different Qt version (older). Download Dependency Walker and open the application executable with it to see where it loads Qt DLLs from. I bet it's different what you think. Most likely either your PATH points to old Qt installation or some other application installed older Qt DLLs to system directories.
