I added header <string> to support string.
My modified code:
string account, gallons;
while(!inpf.eof())
{inpf.get(account, 15, ' ');
inpf.get(gallons, 15, ' '); }
When I compile I get this error:
"'class std::basic_istream<char,struct std::char_traits<char=""> > &__thiscall std::basic_istream<char,struct std::char_traits<char=""> >::get(char *,int,char)' : cannot co
nvert parameter 1 from 'class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >' to 'char *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called"
Any idea why? I am a new to C++

This is about as specific as C++ error messages get.
It means that you provided a std::string where a char* was expected. The C++ compiler had no clue how to convert the string into a char* and threw the error.
You need to give the get()-function a char-array of the length 16 (15 chars you are expecting and one for the trailing zero).

hi! i want to read c source code sample to diable ctrl+alt+del keys combinations in windows 2000. because i have a sample programms listed below but it does not work in windows 2000. hope to hear from u soon.
the sample programms is as :
************************************************start
#include <windows.h>
int WINAPI WinMain (HINSTANCE, HINSTANCE, LPSTR ,int)
{
BOOL old;
SystemParametersInfo( SPI_SCREENSAVERRUNNING, 1, &old, 0);
MessageBox(NULL, "Ctrl-Alt-Del, Alt-Tab, and some other system keys are now disabled. "
"Test this for yourself by pressing some of these key combinations. "
"Note that you can still switch to other applications using the Taskbar buttons. "
"For more precise control over the system keys and task switching operation, get "
"KeyBlock from http://members.aol.com/phord (You can also find the source code to "
"this demo there.)", "Poor Man's KeyBlock demo", MB_OK);
SystemParametersInfo( SPI_SCREENSAVERRUNNING, 0, &old, 0);
return 0;
}

hi,
work on WM_DRAWITEM with struct DRAWITEMSTRUCT
Set CtlType and rcItem to set height of combobox.
The chosen One 
|
|
|
|

There is only one function for setting the size of the DropWindow. Thats MoveWindow. The rectangle you move the window to includes the drop area. When the drop window is not shown, the control limits its client area to the correct height for a combo box. So just use a larger height on your rectangle when you position the window.

I need to do it from the code, to attach a debugger to a process id, just the same as we can do it from the task manager when u right click a process and click debug.
Any help would be appreciated

Check out the following API calls:-
<br />
Private Declare Function DebugActiveProcess Lib "kernel32" (ByVal dwProcessId As Long) As Long<br />
Private Declare Function WaitForDebugEvent Lib "kernel32" (lpDebugEvent As DEBUG_EVENT_BUFFER, ByVal dwMilliseconds As Long) As Long<br />
Private Declare Function ContinueDebugEvent Lib "kernel32" (ByVal dwProcessId As Long, ByVal dwThreadId As Long, ByVal dwContinueStatus As Long) As Long<br />
I only have this in VB - I'm guessing you want a C/C++ example...

Thanks for your help
but i already checked these APIs, and the prob is that im not developping my own debugger i just want to attach to the VC++ debugger. whereas these APIs are issued by the debugger.
Hope you get what i mean

Ah. You mean that you want your application to attach the VC++ debugger to it, rather than attach your program AS the debugger.
Will "MSDEV -p procid -e procid" not do this?

If you want to use the same debugger as configured on the system for just-in-time debugging (which I think is the same as the one used by Task Manager), you can find the path in the Debugger value of the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug.

Which, by an amazing coincidence  is where I checked the command line...

Hi,
i have seen code samples and i would like to know the following
what is the difference or why is it better or why would someone
register a window class and then create a window and then lay a dialog over it instead of just registering the class and creating a dialog?
is there an advantage?
thanks
ps i hope someone understands my question....

Or else way of assighning resources IDs to html-help.
Can you advice better one?
For html files is it better to use extenal editor?
Need be connected to system of html-help creation ?

I declared a varible as a SYSTEMTIME type in my code as:
SYSTEMTIME st;
how to make its value one minute later or one hour later?
Thank you in advance!
|
|
|
|
|
st.wMinute += 1; or
st.wHour += 1;

yep. but watch for 25th hour an 61st minute  . I played with that stuff for an hour until I realized my horrible mistake 
|
|

That sounds a little difficult,I think.
You should care about many things, such as the rolling-over problem, including second to minute,minute to hour,hour to day, day to month, month to year and so on, in which you should also consider the leap problem, whether there are 28 days, 29 days, 30 days, or 31 days in a month.
Can you bring out a better way?
Here is one I can't still have enough condidence.
Convert the varible into a FILETIME or LARGE_INTEGER varible, and then increase the new varible's value. At last convert the varible back.
Herein we know "FILETIME structure is defined as a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601", however I don't know the definition of LARGE_INTEGER
Can somebody tell me some better ways or my last quetion?

if you look to the documentation for SYSTEMTIME:
It is not recommended that you add and subtract values from the SYSTEMTIME structure to obtain relative times. Instead, you should
- Convert the SYSTEMTIME structure to a FILETIME structure.
- Copy the resulting FILETIME structure to a ULARGE_INTEGER structure.
- Use normal 64-bit arithmetic on the ULARGE_INTEGER value.
instead LARGE_INTEGER you can use the __int64 on microsoft compilers
