[split] dll issues

[tobias.hunger]

I just split this out of another thread to make the issue more visible. Hope this helps getting it resolved fast.

I would guess that your buffer overrun corrupts the string you pass. Fix the overrun and your problem should go away.

How to fix over run.

Check http://en.wikipedia.org/wiki/Buffer_overflow for more information on what is going wrong.

If I read the code, it is buggy:

@
Sample App Code:

#include <QLibrary>
#include <QString>
#include <qdebug.h>
 
//Function Pointers
typedef QString (*Data)(QString);
 
int main(int argc, char *argv[])
{
        // ...
        Data  data= (Data) lib.resolve("Data");
        if(bLoaded)
        {
            // ....
              QString strTagInfo = Data(strName);
              // here you use the type, not the pointer?
        }
        // ...
        return a.exec&#40;&#41;;
}

@

I would recommend to rename the pointer data to something like dataFkt or similar, so such things are seen earlier...

Hi Gerolf

I didnt exactly get what you want me to do can you please explain clearly.

[Indrajeet]

Hi Gerolf

That was the typing mistake in actual I was using data() only. But still same problem.

[Indrajeet]

Can anyone please help me to resolve this.

Well, you might provide a small, compilable example that reproduces your problem, which can be downloaded somewhere.
