I am using the "Powercfg.exe" (Power Settings Command-Line Tool) for changing the power settings on different platforms.
The power options (switches) I am using are
1. Enable Hibernation (/HIBERNATION)
2. Enable Device wake (/DEVICEENABLEWAKE)

For Windows XP and Vista these switches work perfectly fine.

The problems I am facing are on Win2K3 and Win2K
1. Win2k3: "Powercfg.exe" do not have the “/DEVICEENABLEWAKE" switch. Is there any another way to configure the device wake enable settings on Win2k3?

2. Win2K: do not have the "Powercfg.exe" command line tool, if we are using the Win2K3 "Powercfg.exe" utility to change the settings. The same issues are there for Win2K as well.

Apart from the command line configurations are there direct APIs available?

I want to use crystal control with setselectionformula()..My application display E instead of displaying report..Its because of exception..

Pleaselet me know how to come out from exception.

Thanks,
Azhar

Please see my code below:

// TODO: Add your control notification handler code here
UpdateData(TRUE);
CCrystalCtrl *m_ControlEmployeewise = (CCrystalCtrl*)(GetDlgItem(IDC_CRYSTALREPORT5));
char cEmployeeID[80];
CString str1;
if(m_nEmployeeID == 0)
{
AfxMessageBox(_T("Employee ID is missing...!"));
CEdit *edit = (CEdit *)GetDlgItem(IDC_EDITEMPID);
edit -> SetFocus();
edit -> SetSel(0,-1);
return;
}
sprintf_s(cEmployeeID,"{Employees.EmployeeID} = %ld",m_nEmployeeID);
str1 = cEmployeeID;//{Employees.EmployeeID} = 76745
m_ControlEmployeewise->SetReportFileName(_T("C:\\Projects\\ServiceRequestApplication\\Report\\Employeewise.rpt"));
m_ControlEmployeewise->SetSelectionFormula(str1);

Hi,everyone!
The style of my CListCtrl is large icon.When I try to insert an item into it,the icon of the new item is always at the end. But the index of the new item is correct.

For example:

before insert F
A C E
B D
after I insert F to index 2,like this:
m_ListCtrl.InsertItem(2,_T("test..."),0);
A C E
B D F
though index of F is 2.

attributes of the list control:
autoarrange-true;sort-none;alignment-left

Anyone can help me? Confused | :confused:

Thanks in advance.

Thanks for your answer,superman.

Actually I've tried this but failed.
After all, i need the autoarrange attribute when removing items.

Now my solution is sorting items by index mannually.
I am waiting for better solutions.

getting data from non-.txt files properly

Is there any way to read files such as .doc, .xls and load their data into a buffer? I used fstream functions to open a file, get its data and put its data in another file. on .txt files it's able to take that data and successfully place it in another txt file fine. however it's not the same for .doc or .xls files (get weird characters, possibly japanese WTF | :WTF:

). was wondering if anyone could suggest an alternative, or a fix on reading data from non .txt files properly.

thanks

Well, .doc and .xls files are binary files. They do not only contain text, but also all extra information (formating, styles, ...). Otherwise, where would this information be saved ?
If you want to read the data in them, you have to use automation (google for word automation and excell automation). The subject is a bit too broad to cover here.

For other file types, it really depends of which type of file you want to open. Each file type has its own format, and you either need to parse the file accordingly to the format (which is probably a though job) or find libraries that do that for you.

Hello,

You've been explained why you can't just open and read XLS and DOC files.

To read XLS files, you can try BasicExcel - A Class to Read and Write to Microsoft Excel[^] or XLW[^]. There are such wrappers around to read/write DOC files as well, just do a search. Smile | :)

Sub programming in C

I'm an experienced mainframe developer familiar with old world languages (COBOL, Assembler etc). I've recently written a couple of C batch programs, now successfully in production. I've now been briefed to write a C subroutine, for use by non C main programs, and have come across a fundamental problem: How do I exit a C subroutine? Is this a design issue ie should the code flow return to the top level where a normal'return' will take control back to the calling code or is there more to it?

The subroutine in C language is called as function.
Do you mean that you have one function which calls another function and soon?
If so, yes you have to keep returning from the functions, either using the return statement or by reaching the end of the function, till you reach the top level function.

Whenever a function calls another function, it puts the return address on the stack just before the second function is called. So if you have a deep level of function calls, the stack has to unwinded properly.

Thanks for your reply; no, my query was about a seperately compiled piece of non-'C' code calling my piece of seperately compile 'C' code. But I think your answer was correct; I need to treat my code as a function so that control returns to the caller by going up the stack and exiting via the final 'return'.

The 'return' statement. Either 'return' for a void function, or 'return value for a non-void function. A void function can also return by reaching hte end of the function. Here are some examples:

void VoidFn(int value)
{
   if (value < 0) return;
   printf("%d", value);
}

int NonVoidFn(int value)
{
   if (value >= 0) return value;
   return -value;
}

You can return from anywhere in a C function, but many people recommend using only a single exit point. Personally, I take the pragmatic approach - if it makes sense to return earlier than the end of a function, then just do it.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

If you've done assembler programming, you should find C very familiar, or easy to pick up, since it mostly operates in a very similar way. You can even view the high-level constructs as wrappers or macros *

Mind you, I'm amazed (or horrified) that wherever you work is just moving from COBOL into C (legacy apps I guess). You've a lot of catching up to do...

[ * OK, that's a huger over-simplification with modern compilers, but for the most part you can convert assembler into C very easily, and vice versa ]

You're right, I've quite enjoyed using C, though I still feel more in control working in assembler. Guess it's an age thing Frown | :(

These last 10 years or so have been spent on migration projects, working for companies moving away from their legacy applications which is why I'm picking up things like C and .NET (I'm an MCP & MCTS now, for all the good it does me!) My specialisation is a mainframe commisioned by NASA as a number crunching machine for the moon project, which shows its age. These machines tend to run large applications which take a lot of redeveloping which is why some still exist.
