My first guess would be a relative vs. absolute path issue.

"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

No, I have checked this. The call work fine if I use it for another child application.

Thanks anyway!

But in your code snippet, commandline is using a relative path. Change it to an absolute path to see what happens.

Well, using

commandline = "C:\\mydir\\runall.exe C:\\mydir\\datafile.txt";

does not help.

What if you use CreateProcess() instead of WinExec()?

The code snippet indicates that some assumptions may not be valid:

1. Does the child program run? Save the result of the WinExec call in
a variable and check it. Add a positive statement that the program was run properly,

2. Does the child program read the command line correctly? You need postive and negative results here too.

3. Can the child process find the input file? WinExec may be able to locate the program to run but the program may not be able to locate the input file. Pay attention to the current directory and how WinExec finds the child program.

My guess is that #3 is the problem since you can run the child program
independently.

Putting values in array

I have two methods.. OnCheck() which will check the record in listview control and another method Onchecklist() which will disabel or enable the buttons. Now my query is I want to check more than 1 record in the listview controls and store the indexes in an array. Then I want to pass each one to the OnCheckEPayList() method.
Any pointers would be greatly helpful.

Thanks,
Sai

Your question isn't clear at all. What are you trying to do exactly ? Please, think that we do not see your code and so we have no idead at all what OnCheck Onchecklist are doing, which buttons you are talking about and what you store in the listview.

Anyway, it seems you are looking for a container class. Did you have a look at std::vector (or std::list) ?

Are you wanting to know which items in the list control are selected? If so, use the GetSelectedCount() and GetNextItem(..., LVNI_SELECTED) methods.

if you are using a CListBox, have a look at GetSelItems, but your list but be set to use multiselect (and/or extended select) style.

if you are using a CListCtrl use CListCtrl::GetSelectedCount and CListCtrl::GetNextItem ( see this[^] )

I have gotten all the code page identifiers using the function EnumSystemCodePages...but i can't seem to find any function that returns the descriptive name of a particular code page...like the names shown in the 'Advanced' tab of Regional and Language Options...anyone know how to get the descriptions?

I just googled with EnumSystemCodePages and the third entry in the list was this --> http://www.codeproject.com/KB/system/codepage.aspx[^]

char cTemp[BUFFER_SIZE];
DWORD nbytes;
CString s;
int iTotBytes = 0;
DWORD n=CeGetFileSize(h,NULL);
if(h!=INVALID_HANDLE_VALUE)
{
//AfxMessageBox("??");

while(CeReadFile(h, cTemp, (DWORD)n,&nbytes,NULL) && (nbytes>=1) )
{

oldFile.Write(cTemp,n);
}
}
