What about:

That doesn't help. This can be reproduced even with this.
CFileDialog dlg(false);
dlg.DoModal();
When Dialog appears, You dont even need to switch the directory. Just enter any filename and then u will not be able to delete that directory. I am stuck here....

This works fine for me:
CFileDialog dlg(FALSE);
dlg.m_ofn.Flags |= OFN_NOCHANGEDIR;
if (dlg.DoModal() == IDOK)
{
CString strPath = dlg.GetPathName();
CopyFile("c:\\somefile.txt", strPath, FALSE);
}Whether I create the folder through Explorer or via CFileDialog, I can remove the folder while the application is running.

Thanx David, that worked. I was thinking on wrong lines I guess. I thought that OFN_ENABLEHOOK was creating some sort of problem bcoz it was hooking it with a global method and the scope of that global method was program-level. So, I was trying to play with OFN_ENABLEHOOK flag and that was not helping.
Anyways, thanx a lot again.

I had developed the client program under Visual C++ 6.0. I use the Windows socket programming. I compile and build my program using the Win32 Console application.There is no errors and warnings. But after I executing the program, I found that if(argc < 3) {
printf("usage: %s <server> <data1> <data2> ... <datan>\n",argv[0]);
exit(1);
}
the output is usage: %s <server> <data1> <data2> ... <datan> and stop with executing the rest of the program.My work is to send data to the server PC which is under the Linux environment.
The following is my program:Thanks for helping.

So does this reproduce the problem:
int main( int argc, char *argv[] )
{
if (argc < 3)
{
printf("usage: %s ... \n", argv[0]);
exit(1);
}
return 0;
}

Thanks for your reply. Now I try to execute this program to send the the data to the Linux computer server which using the BSD socket.Can I doing this just on the console application mode in VC++6.0 without doing the graphical User interface first? What of the steps of doing this?
Anyway, can I know why is its execution stop at usage: %s ... without doing the send()command?
Hoping for your help.Thank you.

Because that's the way you've written the code. If you do not want it to stop, you must remove the call to exit().

Question1:
After I remove all the exit(), I found that the output becomes
"usage: %s ... "
cannot connect:No error
Press any key to continue_
How can I fix this code to execute the whole program?
Question2: Can I just execute this program in the Win32 Console Application under the VC++6.0 to send the data to the Linux computer server which using the BSD socket.Can I doing this just on the console application mode in VC++6.0 without doing the graphical User interface first?Like using DOS to type the location of the executable file? What of the steps of doing this?
Thanks.

If the printf() statement is being called, it's because the if condition that precedes it is evaluating to true.
When sending data via sockets, it matters not what the interface is. Whether it's a console application or a GUI application, those are merely for the user's benefit, not the programs.

Hi. I was wondering if anyone could help me on this: I have to figure out what is the encryption algorithm used to encrypt several words. I have the aplication which can encrypt for me any word I want, so I can build up a dictionary, (clear text <==> encrypted text). This is my project for my encryption course. If anyone could help on this I would be greatful ...

Hi,
I store texts in file in following unicode representation :
&#XXXX;&#YYYY;
This string
& # 1058; & #1077; & #1089; & #1090;
,for example , means "Test" in russian.
My project is built as unicode and i can successfully show this string if i do following:
CString strMsg;
strMsg = (unsigned short) 1058;
strMsg += (unsigned short) 1077;
strMsg += (unsigned short) 1089;
strMsg += (unsigned short) 1090;
TextOutW(....,..,..,..,strMsg,..,..);
My question is : what should i do in order to init string like this :
Code:
CString strText = "& # 1058; & # 1077; & #1089; & #1090;";
so that it will be "treated" as unicode string ? I tried
_T("& # 1058; & # 1077; & #1089; & #1090;") , but it doesn't help..
NOTE - I USED SPACES IN ABOVE POST INSIDE UNICODE STRINGS ON PURPOSE TO PREVENT THEM TO APPEAR AS RUSSIAN CHARS
|
|
|
|

unclear question:
CString strText = "& # 1058; & # 1077; & #1089; & #1090;";
do you mean values in the string:
first byte is: '&'
second byte is: '#'
next 2 bytes are: 1058
etc?

No, I mean unicode representation of string.
Т = 'T' , е = 'e' , с = 's' ; т = 't' (in russian)

I'm quiet a beginner and it's kind of difficult to discribe my problem. Let's try. I'm programming a SDI application, with the possibilty to run this programm on the console. Now my question: How can i output text to the console? I've already tried WriteConsole, but this seems to work only if you allocate a new console. But i want to write to the console i'm starting the programm from. Can anyone give me a hint?
|

|

Yes, you're right, you need to create a console for output if you're using WriteConsole().
If you want to output it to the caller's console, then you need to create the output console HANDLE in the caller, starting program, thread, fibre, whatever, and pass the output console HANDLE to whatever you're trying start up (How you do that is up to you - commandline args, thread args - etc, etc). Then you should be able to use WriteConsole() using the handle passed to it.
Now, if I may comment.
The reason that SDI, MDI, and any other windowing programmes exist is that they expect user input, even if it is only a mouse click, or there are special circumstances for output - just have a look at all the processes running on your computer - guaranteed that most are background tasks with no user interface or the user interface is mediated by a second programme.
If you want to write a 'console' programme then you don't need all the baggage that comes with windowing.
If you want to write a programme that needs even moderately complicated user interaction, then think about the model you're using.
|
|
|
|
|
Thanks first! I'll try to follow your advice with the handle.
The reason for using a SDI is, that in the end there shall be a programm, that can be run either in console mode by passing the parameters directly or in GUI mode, when there are no parameters given in the command line. But i'm just beginning this project.

If tried that, but it doesn't seem to work with SDI. Thanks anyway.

I've managed the problem by changing the linker settings.
- from /subsystem:windows to /subsystem:console (Project - Settings - Link - Project Options edit box)
- WinMainCRTStartup as Entry-point symbol (Project - Settings - Link - Output - Entry-point symbol).
Now it's possible to use printf as well as WriteConsole.

HI
I am Creating ChecklistBox it shows Vertical Scroll Bar but not Horizental why ? I am using Horizental Scroll bar style.
Reply me urgent
Code is below
int CChkListDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CDialog::OnCreate(lpCreateStruct) == -1)
return -1;
// TODO: Add your specialized creation code here
DWORD dwStyle = WS_CHILD | WS_BORDER | WS_VISIBLE | WS_VSCROLL|
WS_HSCROLL | LBS_HASSTRINGS | LBS_NOTIFY;
// Abov style has Horiztl and Vertcl Scroll Style
CRect rcDlg;
GetWindowRect(&rcDlg);
ScreenToClient(&rcDlg);
int L = (int)( 7.0 * rcDlg.Width() / 157.0);
int T = (int)( 19.0 * rcDlg.Height() / 167.0);
int R = (int)( 148.0 * rcDlg.Width() / 157.0);
int B = (int)( 118.0 * rcDlg.Height() / 167.0);
CRect ReqRect(L, T, R, B);
m_ChkListBox.Create(dwStyle, ReqRect, this, IDC_CHKFORCEDVAR);
Font.CreatePointFont(8 * 10, "Arial");
m_ChkListBox.SetFont(&Font);
for(int i=0; i<10 ; i++)
{
CString str;
str= " Data ";
m_ChkListBox.AddString(str);
}
return 0;
}
Regards.

my brother,
Listbox initially donot display horizontal scrollbar, we have to call a member function of listbox which sets the actual width internally , when this width is given larger then the width in Listbox::Create the listbox shows horizontal scrollbar
i have used this method but at this time i am not remembring the actual name of the function, you can check docummentation for Listbox
i think name is
SetHorizontalExtent( int );
Note this function takes only one int value , which represents the width.

}
m_ConsChkListBox.ReleaseDC(pDC);
// Set the horizontal extent so every character of all strings
// can be scrolled to.
m_ConsChkListBox.SetHorizontalExtent(dx);
return true;
}
waitng for ut reply
thanx

You have to set the show Horizontal Toolbar and implement a function like following:
call it when you have added the items...
good luck.
PS: Although probably not intended, your mail almost seems unpolite. Don't sweat it, It won't keep me up at night , but try to take care of your language.
void DlgFlexListSelectValue::SetHorizontalScrollBar(){<br />
CString str;<br />
CSize sz;<br />
int dx = 0;<br />
TEXTMETRIC tm;<br />
CDC* pDC = m_valueList.GetDC();<br />
CFont* pFont = m_valueList.GetFont();<br />
<br />
CFont* pOldFont = pDC->SelectObject(pFont);<br />
pDC->GetTextMetrics(&tm); <br />
<br />
for(int i = 0; i < m_valueList.GetCount(); i++){<br />
m_valueList.GetText(i, str);<br />
sz = pDC->GetTextExtent(str);<br />
<br />
sz.cx += tm.tmAveCharWidth;<br />
<br />
if(sz.cx > dx){<br />
dx = sz.cx;<br />
}
}
<br />
pDC->SelectObject(pOldFont);<br />
m_valueList.ReleaseDC(pDC);<br />
m_valueList.SetHorizontalExtent(dx);<br />
}
