As soon as start program, not operate on any array yet, got error message: Unhandled exception at 0x77c315de in blast_frag.exe: 0xC00000FD: Stack overflow. Please help why ? Thanks

CString ftitle; fscanf_s(f_ptr_seed_inf,"%s\n",ftitle[ifl].GetBuffer(MAX_PATH)); ftitle[ifl].ReleaseBuffer(); I got error message: Unhandled exception at 0x776015de in MSW_Vib_Model.exe: 0x00000000: The operation completed successfully. Please help

I got this error message when I debug: Unhandled exception at 0x77a915de in MSW_Vib_Model.exe: 0x00000000: The operation completed successfully. from these code segments: // ifl=0; do { { // fscanf_s(f_ptr_seed_inf,"%lf %lf %s\n",&sd_dis[ifl],&time_onset[ifl], ftitle[ifl].GetBuffer(MAX_PATH)); ftitle[ifl].ReleaseBuffer(); } ifl += 1; } while (!feof(f_ptr_seed_inf)&&(ifl<120)); nfile=ifl; // This is my input file: 4171.000 0.28600 ECO61_4171_Hole1_seeds.txt 4157.000 0.24600 ECO61_4157_Hole2_seeds.txt Please help me.

How to spacify the width of a string in 'scanf_s' ? I feel hard, since the width of the string in the input file is not fixed varying from 50 character to 120, so how to specify the buffer size. I used 'scanf' to read input, I do not need to specify the length of the string. Please advise. Thanks

Hi Gurus, Could you provide me some codes examples to use: 'fopen_s' and 'fscanf_s'. Thanks

I got the following compile error message, for using: srand(time(NULL)); warning C4244: 'argument' : conversion from 'time_t' to 'unsigned int', possible loss of data Thanks

thank you, really helped me.

It seems that the following format "%f\n" for reading a double not working. Please help: fscanf( f_ptr_seed_inf,"%f\n",&sam_interval); Thanks

Thank you for your helpful correction. If I change all 'float' type to double, my program would be too large. How about change all types to 'float' ? Thanks

Thanks Guys.

thanks a lot. Do I have to install visual studio 2008 for converting my visual c++ 6 (2003) ? Please give me some guidances. hanks again

I need to convert my programs from c++ 6 to Visual stutio professional 2010. Please advise how to proceed and what I need to fix typically ? What is the best way to do this ? Thanks Ruilin

Thanks for all guys who made suggestion above. When I debug I got error message: "user break point called from code at 0x7c90120e" -> 7C90120E int 3 Please help, Thanks

When I run my program I got: Debug Assertion Failed! Program: F:\Debug\abvb.exe File: dbgheap.c Line:1044 Expression: _CrtIsValidHeapPointer(pUserData) Please give me a direction on how to find the problem. Thanks

Thanks for the useful comments. Yes, the subroutine would check the linear - dependency between equations and exclude those redundent equations. Yes, a least square technique is required to fine the mean and standard deviations.
