Using the win32 api, you could do something like this snippet here:
char caData[256];
caData[0] = 0;
GetLocaleInfo(LOCALE_SYSTEM_DEFAULT,LOCALE_SSHORTDATE,caData,sizeof(caData)-1);
m_cShortDateFormat = CString(caData);
char *p = caData;
while (*p && *p == ' ')
p++;
switch (*p)
{
case 'd':
m_cClientFormValidationDateFormat = "D/M/Y";
break;
case 'Y':
m_cClientFormValidationDateFormat = "Y/M/D";
break;
case 'M':
default:
m_cClientFormValidationDateFormat = "M/D/Y";
break;
}
onwards and upwards...

Something like:
CString strDate;
COleDateTime date;
date.ParseDateTime(strDate, VAR_DATEVALUEONLY);
TRACE("Day = %d\n", date.GetDay());

Hi,
I'm using ClistCtrl to display some data I'm receiving.
I need to display only the updated data,so the old data will disappear when there is new data to display(i get new data every 200msec).
The problem is that my ListCtrl is flickering when I'm calling
MyList.DeleteAllItems() function(I'm doing it with timer event).
How can I avoid this annoying flickering?
With best regards,
Eli

Instead of using DeleteAllItems(), use CustomDraw message handler and in that one include to DeleteAllItems() and insert the new data.

Hi Neelesh,
Thanks for your prompt reply.
Do you have any example how to do this?
How should I use the CustomDraw message handler?
Regards,
Eli

Eli,
you can see the article "Dynamically Highlight Elements in a List Control" at http://www.codeproject.com/listctrl/highlightlistctrl.asp

How about a call to SetRedraw() before and after the insert/delete operations?

I'd try this first:
SetRedraw
If you still get flicker, try drawing offscreen:
Flicker free drawing of any control

You can disable the painting on the list control with SetRedraw(FALSE);
I'm using this technique when updating my list controls.
m_lstCtrl.SetRedraw(FALSE);
m_lstCtrl.DeleteAllItems();
...
m_lstCtrl.SetRedraw(TRUE);
IMO this is easier than trying to implement Custom or Owner Draw

Hello
You can place your app path into registry under the key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

hi all..I'm newbie in visual c++ and I'm trying to make a simple file copy program, but it doesn't work. Here is my source code:
#include<afx.h>
#include<stdio.h>
int main()
{
CFile m_LogFile,m_DataFile;
char* a=NULL;
m_DataFile.Open("E:/data.txt", CFile::modeRead|CFile::shareDenyNone);
try
{
m_LogFile.Open("E:/data1.txt", CFile::modeWrite|CFile::modeRead|CFile::modeCreate|CFile::modeNoTruncate|CFile::shareDenyNone);
m_LogFile.SeekToEnd();
}
catch(CException* e)
{
e->ReportError();
e->Delete();
}
m_DataFile.Read(a,m_DataFile.GetLength);
m_LogFile.Write(a,strlen(a));
return 0;
}
The message error said that the m_DataFile.Read(a,m_DataFile.GetLength); part is wrong, but when I change the 2nd parameter into fixed number(I tried 10 and 100), it generate other error. Can somebody help me?
thx

I can't find it, but there is most certainly an API call you can make to copy a file, if you want to. In the meantime, m_DataFile.GetLength is a function pointer. m_DataFile.GetLength() is a function call.

It is CopyFile(...)

Thanks - I thought it was, but I did a google on CopyFile C++ and got no helpful links. Usually, MSDN is the first hit in a case like that.

1- Change m_DataFile.Read(a,m_DataFile.GetLength); to:
m_DataFile.Read(a,m_DataFile.GetLength());
because GetLength() is a function.
2- And also, you are using char* a = NULL;
You are not assigning any memory to it. It is a null pointer.
You can try this:
char* a = NULL;
a = m_DataFile.GetLength() + 1;
memset(a,0,m_DataFile.GetLength()+1);
Then read the file into it:
m_DataFile.Read(a,m_DataFile.GetLength());
this is this.

I already change the source code..but it is still error. This is my source code:
#include<afx.h>
#include<stdio.h>
#include<memory.h>
int main()
{
CFile m_LogFile,m_DataFile;
char* a=NULL;
m_DataFile.Open("E:/data.txt", CFile::modeRead|CFile::shareDenyNone);
try
{
m_LogFile.Open("E:/data1.txt", CFile::modeWrite|CFile::modeRead|CFile::modeCreate|CFile::modeNoTruncate|CFile::shareDenyNone);
m_LogFile.SeekToEnd();
}
catch(CException* e)
{
e->ReportError();
e->Delete();
}
memset(a,0,m_DataFile.GetLength()+1);
m_DataFile.Read(a,m_DataFile.GetLength());
m_LogFile.Write(a,strlen(a));
return 0;
}
n the program generate these errors:
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
Debug/excel.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.
excel.exe - 3 error(s), 0 warning(s)
n I don't understand what it's means...pls help.
thx

If you're using VC 6. do the following:
Menu item Project->Settings->Tab C++ -> Category 'Code Generation'->
set this option to 'Multithreaded' or 'Debug Multithreaded'
|
|
|
|
|
I already change the code generation into multithreaded. The program can be compiled successfully but when I run it, it generate an error and can't run. Give me some hints please. Is there any logic error on my program?
The reason that I didn't use CopyFile is if the program works, I'm planning to make a program that can make XML file from text file which I think it can't be done using CopyFile function.
thx.

And what would that error be?

Remove the /MT linker option.
