The valueof ESP was not properly saved across fucntion call.This is usally a result of calling a fucntion declared with one calling convention with a function pointer
declared witha declared calling convention..

In C/C++ settings it is _cdecl convention.

the code is which i am coverting bmp to png format

C#

char *inBuffer = new char[inStreamSize];

        uncompressedBufferSize = inStreamSize*40;
        unCompressedBuffer = new char[uncompressedBufferSize];

        inFile.read (inBuffer, inStreamSize);
        //inStreamSize = inFile.gcount();

        zs = new z_stream;
        zs->next_in   = (unsigned char *)inBuffer;  //point to beginning of compressed file
        zs->avail_in  = inFile.gcount();                   //specify the size of the compressed file
        zs->next_out  = (unsigned char *)unCompressedBuffer;  //point to where the uncompressed file will be
        zs->avail_out = uncompressedBufferSize;   //specify size of buffer to hold uncompressed file
        zs->zalloc    = (alloc_func)0;
        zs->zfree     = (free_func)0;
        zs->data_type = Z_BINARY;

        ret = inflateInit(zs);



        ret = inflate(zs, Z_FINISH);
        if(ret != Z_OK && ret != Z_STREAM_END)
        {
            AfxMessageBox("Failed to decompress file");
             inFile.close();
             outFile.close();
            return TRUE;
        }

        ret = inflateEnd (zs);


        if(ret == Z_OK)
        {
            outFile.write (unCompressedBuffer, zs->total_out);
            m_ctrlFileProgress.StepIt();
            CreateBMPFiles(unCompressedBuffer, zs->total_out);
            m_ctrlFileProgress.StepIt();
        //  m_ctrlFileProgress.StepIt();
            CreateLogFile(unCompressedBuffer);
            m_ctrlFileProgress.StepIt();

        }
//cleanup:
         inFile.close();
             outFile.close();

        delete [] zs;
        delete[] unCompressedBuffer;
        delete[] inBuffer;


    }
    m_ctrlFileProgress.SetPos(4);
    SetDlgItemText(IDC_PROGRESS_TEXT, "1 File Converted");
    AfxMessageBox("Decompression Complete");

    return TRUE;
}

after this the error occurs.

Message displays correct like "Decompression Complete",after that come out of this loop and error message displays

Program:my.exe

Solution 2

as the error message says, this usually happens when you call an external library using the wrong calling convention.

i don't see anything obviously wrong with the code you've shown here. double-check the function declarations for any DLLs you're using.

Will zlib.dll makes difference in this which iam using 1.4 version here and it should be compatible.is it true ?confirm. Other than zlib.dll i am not using any DLL.

C^hris L^osinger 26-Apr-12 9:29am

how are you #including the zLib header?

JOYKAIGA1 26-Apr-12 9:38am

I am adding in external dependencies zlib files zlib.h file.

2) in vc6.0 settings->links>library/modules options ->i am adding zlib.lib

C^hris L^osinger 26-Apr-12 9:40am

when you #include "zlib.h", are you doing this:

#ifdef __cplusplus
extern "C" {
#endif
#include "zlib.h"
#ifdef __cplusplus
}
#endif

?

JOYKAIGA1 26-Apr-12 9:49am

i added include 'zlib.h' in header file. also #ifdef __cplusplus
extern "C" {
#endif
.still error occurs .

C^hris L^osinger 26-Apr-12 10:02am

are you using any other (non-MS) external libraries ? (statically linked)

JOYKAIGA1 26-Apr-12 10:03am

using like basesd.h and zconf.h

C^hris L^osinger 26-Apr-12 10:06am

did you build the copy of zlib.dll that you are using?

JOYKAIGA1 26-Apr-12 10:10am

yes.

also i observed if comment following lines like
/* zs->next_in = (unsigned char *)inBuffer; //point to beginning of compressed file
zs->avail_in = inFile.gcount(); //specify the size of the compressed file
zs->next_out = (unsigned char *)unCompressedBuffer; //point to where the uncompressed file will be
zs->avail_out = uncompressedBufferSize; //specify size of buffer to hold uncompressed file
zs->zalloc = (alloc_func)0;
zs->zfree = (free_func)0;
zs->data_type = Z_BINARY;

ret = inflateInit(zs);

ret = inflate(zs, Z_FINISH);
if(ret != Z_OK && ret != Z_STREAM_END)
{
AfxMessageBox("Failed to decompress file");
inFile.close();
outFile.close();
return TRUE;
}

ret = inflateEnd (zs);

if(ret == Z_OK)
{
outFile.write (unCompressedBuffer, zs->total_out);
m_ctrlFileProgress.StepIt();
CreateBMPFiles(unCompressedBuffer, zs->total_out);
m_ctrlFileProgress.StepIt();
// m_ctrlFileProgress.StepIt();
CreateLogFile(unCompressedBuffer);
m_ctrlFileProgress.StepIt();

}
//cleanup:
inFile.close();
outFile.close();
*/

error do not occur.

C^hris L^osinger 26-Apr-12 10:26am

can you try commenting-out just the calls to zlib ?

JOYKAIGA1 26-Apr-12 10:28am

can u brief commenting calls to zlib means?

C^hris L^osinger 26-Apr-12 10:47am

the zlib calls are inflate, inflateInit, inflateEnd.

if commenting those out eliminates the crash, then the problem is probably that the zlib functions are not being exported from the DLL with the calling convention that your application expects.

what did you do to get zlib to compile as a DLL?

JOYKAIGA1 26-Apr-12 10:38am

i comented lines mentioned below here error not comming.
other than this lines if i comment error comes occurs and application crash.
/* ret = inflateInit(zs);

ret = inflate(zs, Z_FINISH);
if(ret != Z_OK && ret != Z_STREAM_END)
{
AfxMessageBox("Failed to decompress file");
inFile.close();
outFile.close();
return TRUE;
}

ret = inflateEnd (zs);
*/

JOYKAIGA1 26-Apr-12 10:50am

i had downloaded zlib sources frm zlib website with version required to get the zlib.dll.Also i builed and compiled andthere is no errors in zlib

C^hris L^osinger 26-Apr-12 11:05am

can you show me the link that you downloaded?

JOYKAIGA1 27-Apr-12 7:26am

http://www.zlib.net/

surely error is within these functions inflate, inflateInit, inflateEnd.
here it is not considering.
can you tell me how to delete zlib.h in external dependcies folder and add new version to the dsw

C^hris L^osinger 27-Apr-12 7:28am

you can't delete anything from the external dependencies folder. that folder is just to show you the files that have been included based on your #include statements and the include paths you've defined.

JOYKAIGA1 27-Apr-12 9:02am

still error exist even i build latest verison of zlib files/dll?

C^hris L^osinger 27-Apr-12 9:08am

what preprocessor symbols are you defining when you build zlib, and which are you defining when you build your project?

JOYKAIGA1 27-Apr-12 9:20am

#include "zlib.h"

C^hris L^osinger 27-Apr-12 9:30am

go to Project / Settings / C|C++ . do you you have anything in the "Preprocessor definitions" field?

JOYKAIGA1 30-Apr-12 1:38am

while compiling zlib files,preprocessor definationa field having below mentioned.DEBUG,DYNAMIC_CRC_TABLE,NO_GZIP,WIN32,_LIB
.
Where as in my project the preprocessor defination field having below mentioned
WIN32,_DEBUG,_WINDOWS,_AFXDLL,_MBCS,_LIB

JOYKAIGA1 30-Apr-12 5:07am

Chris,If i run the same project in Qt4.7 version ,it is running sucesfully with 0utany eroors.
