I'm using ShellExecuteEx to run some external programs, but I need to know
what the return code of the process is. and the return code of
ShellExecuteEx, which indicates problems with starting the process anyonr know this?

Have you seen SHELLEXECUTEINFO-->hInstApp ?

you can use GetExitCodeProcess() to get the exit code of the process. You need to pass the handle of the newley created process into this function. you can get the process handle from SHELLEXECUTEINFO structure that you passed to the ShellExecuteEx

Try code like this:
#include "stdafx.h"
#include <shellapi.h>
#pragma comment(lib, "shell32.lib")
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
SHELLEXECUTEINFO sei = {0};
sei.cbSize = sizeof(sei);
sei.fMask = SEE_MASK_NOCLOSEPROCESS;
sei.lpVerb = "open";
sei.lpFile = "C:\\Windows\\Notepad.exe";
sei.nShow = SW_NORMAL;
BOOL bOK = ShellExecuteEx(&sei);
if (bOK)
{
WaitForSingleObject(sei.hProcess, INFINITE);
DWORD ExitCode;
if (GetExitCodeProcess(sei.hProcess, &ExitCode));
{
}
CloseHandle(sei.hProcess);
}
return 0;
}

Hi, i have been working on an assignment for uni for the past week. Every week we get a new assignment, we create a small program and write a report showing a time log, defect report, etc. This one is a program to count Lines Of Code, in particular, class/object LOC.
I couldn't get it working so i submitted the buggy one, but i still need it complete to do the other assignments. Can someone take a look at it and tell me what's wrong, in particular this bit:
void trim(string& str) {
string::size_type pos = 0, n1 = 0, n2 = 0;
while (n1 < str.length() || n2 < str.length()) {
if ((n2 = str.find('\n', n1)) == string::npos)
break;
pos = str.find_last_not_of(" \t", n2);
if(pos != string::npos && pos > n1) {
str.erase(pos+1, n2-(pos+1));
n2 = pos + 1;
pos = str.find_first_not_of(" \t", n1);
if(pos != string::npos) {
str.erase(n1, pos-n1);
n2 -= pos;
}
}
else
str.erase(n1, n2-n1);
n1 = n2 + 1;
}
}
which should trim whitespace from the beginning & end of each line + remove any blank lines.
I have noticed that the string removal code is also buggy, i don't know what's wrong but it doesn't quite remove everything between " and "

Thanks, that's good. But i would still like to fix mine and get it working.

I hope you do not mind, but I am confused. You simply start at the beginning of the line and remove white spaces. Getting the total is more efficient before you remove them, but not necessary. The same can be said for the actual end of the string..
Your code is tight (which I like); my only question is why are you looking for “ \t” (“{space}TAB”)? The goal is to eliminate white space and not a combination of white spaces.
I admit I did not look deeper than that, but one flaw at a time.

It seems to me as this is an excellent opportunity to use the debugger!
Just set a breakpoint at the first line of the function, then single-step it.

That's a good idea. I used Dev-Cpp's debugger yesterday, but i don't like it all that much. I prefer just inserting cout's to debug.
And what i am trying to do with the code it count object lines of code & the LOC of each function in that object. So i need to be able to read function names, which is why i am not just simply removing all whitespace.
Also, i realized the other day that i am compiling/running it on Unix as well as Windows so newlines are a problem. I thought getline() just got a line regardless of the format but it actually only uses \n as a delimiter so i might be getting some errors if there are some \r in there too

I just want to know how to get a pe file's size through the PE file its self.That is no API is used,just look up the data structure of the pe.
I have checked the winnt.h and can't find a useful data member to show the size of the pe file.
Don't look at me in that way!

Hey,
I consider you must be using MFC Use a CFile object to get the length of the file and that length would be the size of file in bytes
like this..
CFile obj;
double len;
CString sLen;
if(obj.Open("C:\\a\\a.exe",CFile::modeRead))
{
len = obj.GetLength();
len /= 1024;
sLen.Format("%10f",len);
AfxMessageBox(sLen);
}
obj.Close();
This code will give you the size of PE file in kilobytes

But if I have a pe file and then I append some data to the file,I want to get the original pe file size,not the size after modified!
I skim the winnt.h and find that I must sum all the section size and directory size to count the size of pe file.I want to if there is a structure member in the pe file that can show me the size directly!
Thanks for help!

At first!Thank you for help!
I just want to get the orginal pe file's size,maybe the pe file was modified by some other program(ex.Append some data to the end of the orginal pe file).So the size I get from API is not the size of the original file.
I want to get the original pe file size ,so I have to follow the pe format and sum all it's section size and directory size.
Can you help me on getting a easy way to find out the original file size!
Thank you very much!

The scenario here is that I have a main dialog. When I press a certain button, a new dialog appears.
Along with this new dialog, I also have a 2nd new dialog not really a part of the application itself, a settings dialog of a scanner which was just invoked by my application. So basically, I have to new dialogs.
What I want to do is to put the 2nd dialog on top of the 1st. The problem is after OnInitDialog() of the 1st, ShowWindow() is invoked so it stays on top. The 2nd dialog must be on top of my application only, not on other windows.
Any help would greatly appreciated. Please tell me if you need more information.
Thanks!

Use SetWindowPos.
SetWindowPos(hwndDlgTobeOnTop,
hwndAppDlg, ...).
|
|
|
|
|
yeah, i did that too.. the 2nd dialog is invoked inside OnInitDialog of the 1st. So even if I called SetWindowPos, after the call to OnInitDialog, the 1st stays on top of the 2nd because of the implicit call to ShowWindow().
Both dialogs must appear at the same time only that the 2nd needs to be on top of the 1st.

Hello There,
This is my first post..so bear with me if I am bad at explanation!I am not able to solve this n need immediately for project..so.. 
I need to Load some data from XML document into ComboBox,but I want to error out if I have duplicate data.
Ex:-
<Employees>
<Employee Name"AAA">
<ID>1<ID/>
<Employee>
<Employee Name"ABC">
<ID>2<ID/>
<ID>2<ID/>
<Employee>
<Employee Name"AAA">
<ID>1<ID/>
<Employee>
<Employees/>
Here I need to load comboBox1 with AAA and ABC and show up error that there is Duplicate entry for an Employee NAme="AAA".
I need to load second Combo Box with ID's.And Error out if there are duplicate entries for this.
I ran an Xpath Query
CString strQuery ("//Employees/Employee");
_bstr_t QueryString;
QueryString = strQuery.AllocSysString();
CString strName ("name");
_bstr_t name;
name = strName.AllocSysString();
HRESULT hr15 = m_pXMLDocClassLevelDoc->selectNodes(QueryString,&pNodeListPtr);
then in the for loop I do get_item & get_attribute and get the data in BSTR.
For loading the 2nd ComboBox I run another query with
strQuery.Format("//Employees/Employee[@ID='%s']",strdata1); where strdata1 is selected Employee name in Combo Box1(did it in OnComboSelChange Event).
So I need to show error in MEssageBox with what is duplicated in the XMLDoc.Example here is "AAA"- Employee name or ID= 2.
Please help me on this.
Thanks.

Have you tried running it through debugger, and what call stack says ?

This is very insufficient information, to guess the problem.

Absolutely not, but like prasad_som said we do not have enough information.
What is the prototype of ‘DrawLed”?
You did not give the header, and more importantly you did not state the library. Without those it is a total mystery.
