i have 20 edit box on my dialog, it was formated into 4 rows with 5 edit box with each row.
these edit box displays integers. i want to save/load the integers to/from a .txt file.
the .txt file should have the following format,each number corresponds to each edit box, and each row corresponds to each row of edit box:
50,5,3,2,6
32,56,7,8,9
12,34,56,7,9
1,2,4,5,6
1,2,3,4,5
the numbers are just above is just an example.
How i do this?
thx

Did you try anything yet? 
You can just read the file to get each values and set to each edit control.
Where did you stuck?

i've made a button to open a cfiledialog box,and assoicate a CFile with a CArchive
<br />
if( FileDlg.DoModal() == IDOK )<br />
{<br />
if( f.Open(FileDlg.GetFileName(), CFile::modeRead) == FALSE )<br />
return;<br />
CArchive ar(&f, CArchive::load);<br />
.....<br />
after this, i don't know the exact the syntax to load the data from the .txt file.
is it better to create a data buffer and then load the data into the data buffer?
i wish to seperate the data by comma and clarity, but of course i don't want to load the commas, what's the syntax??
thx

Note: your example data is 5 rows with 5 edit boxes each.
First time getting data from a file, eh?;P

char cBuffer[MAX_SIZE];
if (f.GetLength() > sizeof(cBuffer))
{
AfxMessageBox("I theenk I need a beegger box!", MB_OK|MB_ICONERROR|MB_SETFOREGROUND);
} else {
if (f.Read(cBuffer, sizeof(cBuffer)))
{
int ia=0, ib=0, ic=0, id=0, ie=0;
if (4 == sscanf(cBuffer, "%d,%d,%d,%d,%d\n", ia, ib, ic, id, ie))
{
}
}
}

Hello guys,
Good day to you. I have a coded an MFC application which uses the XML library to create XML data and send it through TCP/IP. Now, I need to compile the code and create a .exe that will run to another PC which unfortunately has no Visual Studio installed.
I tried this before with another code and it worked just by setting on the project settings -> use static library. Though the problem with my current code is that it pops-up this error:
cl : command line error D8016 : command line option '/MTd' and '/clr:oldsyntax' cannot be used at the same time
Now, I solved this problem but it made another. As it turns out, somehow I am using managed code with unmanaged (I dont know if the term is right) which I cant.
Please help me with this, I just need to create the .exe file for another PC without VS. Thank you for your time.

I tweaked some options and replaced /MTd with /MD. And it works with the use static library for MFC. Though I tried to run it in another PC without VS but it still does not work.  I really need to deploy this and installing the whole VS in the target PC is not an option. Does anyone have any suggestions? Like maybe creating the installer for my project or something. Thank you very much.

If you are using MFC based application than it is necessary to install some dll on another pc. on C:\windows\system32. MFC42D.dll , ole32.dll
may be it will work.
Yes U Can ...If U Can ,Dream it , U can do it ...ICAN

There is a tool in Visual Studio 'Depends' which can be used to find out the dependant dlls of your executables. You can find the Depends.exe in Visual Studio Bin Folder. Just Drag and drop your executable into the Depends window to show the list of dependant dlls. Though it lists all the dlls the exe uses certain common dlls like user32.dll and kernel32.dll will be available in the target system.
You need to find out MFC dlls normally these dlls are needed for an MFC application
MFC42D.dll,MSVCRTD.dll, MFC042D.dll (These are debug mode dlls, release mode uses the corresponding dlls with out 'D' in the name)
If you copy all the required dlls and your executable in a singlre folder and try to run this exe from your end system with out VS, this should run.
Some times if you are using some com components as part of your exe, you need to copy that com dll also to the end system, and have to call regsvr32 to register that com component on the end system before trying to execute your program
From your query, its not clear what is the error coming when you are trying to run your exe on User System with out VS?
Cheers, Arun Krishnan

BTW, never distribute an exe that has been built in Debug mode !

Finally solved it! I was never aware of this Depends.exe. Thank you very much for the help! This is just what I am looking for.  Again, thank you for the time and help!

try to open the exe in dependency viewer and note all the dlls used by that exe. On another pc all these dlls need to be present..
dependency viewer is available in vc++ 6 tools

|
|
|
Yes. Its placed inside the tools folder, it's the first time I encountered this application. Thank you for the help and time!

Hi
STL string class "substr" method allocates on the heap? I was watching memory window that seems to be true - that the returned string has an entirely different address (relative to input string)
<br />
string str("Hello");<br />
...<br />
str.substr(lastPos, pos - lastPos)<br />
Thanks!

From MSDN substr() page ...
Return Value
A substring object that is a copy of elements of the string operand beginning at the position specified by the first argument.
It IS a copy. Different implementations of the STL handle allocating memory for strings differntly but there is a good chance its allocating memory on the heap.
With most versions of Visual Studio you get the full source code for the STL so you could easily answer this yourself with some investigation

Does anyone know what API I can use to determine the CPU time used by a process? This is not the same as elapsed time!

Alright it seem the GetProcessTimes API does what I was looking for

You can also use PDH library for this.

Hi,
I'm using a C++(native) in VS2005. And when I manually add some member variables or methods the intellisence can't handle this and when I'm trying to build the application(MFC executable) it crushes the VS2005 IDE.
After that I've to manually delete the intellisence database file (*.ncb) and open solution for compilation again.
The question is:
- Is there any way (some hot key or IDE macro) to enforce manually intellisence update from the VS2005 IDE?
This would solve my problem.
Thanks,
Oleg.
