can you tell me the same how to do using fseek() etc?as i am using only iostream and ifstream?

Also tell me in File1.bin ,we have archive files(pdf files) individually compressed.how to read and store the file data and contents in a buffer or separate directory in a order ?

for each pdf file there is associated fruit mapping ,like this around 1 lakh pdf files are there and 50 fruits are there.these are meta data stored in dbf files. tell me how to write into a file with this associating fruits ?

any updates on this error?

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

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

#include "zlib.h"

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

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

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

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);
*/

can u brief commenting calls to zlib means?

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.

using like basesd.h and zconf.h

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

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

can you brief more about this in which file to be added ?

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.

what is the solution to add an extra chunk in the image?can you tell me how to define own custom chunk type ?

this is what displays in call stack

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

Program:my.exe
debug error File i386\chkesp.c
Line 42
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..

adding/insert chunk means like to add text/label into the image
