I reallize that.I modified my post,too. It's always better to use pre tags for code. It makes code readable. I just missed it, on this occasion.
You code in OnCtlColor could be like this,
HBRUSH CExpDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
switch (nCtlColor)
{
case CTLCOLOR_EDIT:
{
hbr=CreateSolidBrush(c);
return hbr;
}
}
return hbr;
}

what do you mean by this? Can you be more clear. If you mean , it doesn't immediately paint, then you need to call Invalidate, on CEdit class.

You need not call this.

hi prasad,
You are correct i forgot to call the ::Invalidate(...) method to reflect the Immediate Changes.

When we mount two paritions of a USB drive (HDD) such that Drive A: is mounted in a folder of drive B: and Dirve B: is mounted in a folder of Drive A: i.e. create recursive mount points. Thus the mounted points (folders in which drive are mounted) have current GUIDs of the partitions of USB drive. If user plug off this USB drive and plug on to another system. Thus the system will assign new GUIDs to USB drive partitions. But the mounted points previously created have olders GUIDs i.e. the one that was assigned to these folders when the mount points were created (NOTE: we get these GUIDs using DeviceIoControl). So, when we pass these GUIDs as path to the CreateFile method, it fails because new GUIDs are assigned to the partitions. But these GUIDs are valid if we pass as path in CFileFind.
So, what is actually happening in these cases i.e. for CreateFile and CFileFind ?
How these mount points (created on USB drive) be valid on the other system ? Although these mounts are valid if we access through windows explorer.

Hello!
Anybody knows how to make EditBox to accept only bitwise strings (0 and 1), something like ES_NUMBER that allows only digits to be entered into the Edit Control.
SzyKam.

I don't know such a control but you can do one yourself quite easily: create a new class (CBitwisEdit for example) that inherits from the CEditCtrl. Override the OnChar function. Inside this function, check if the char entered is either '0' or '1'. If this is the case, call CEditCtrl::OnChar, otherwise don't call it.

hi,
In order to Accept Numeric Values in the EditControl, You have to SubClass the EditControl by Creating a new CEdit Class and specify the Messages.
In our Instance WM_CHAR. in the WM_Char Message check for the Only Numeric Variable.
Think Clever.

It seems you need to
<br />
<br />
FindWindowEx(FindWindow("Shell_TrayWnd", NULL)->m_hWnd, <br />
0, "Button", NULL)->ShowWindow(0);<br />
<br />
FindWindowEx(FindWindow("Shell_TrayWnd", NULL)->m_hWnd, <br />
0, "Button", NULL)->ShowWindow(1);<br />
<br />
<br />

do you think seriously (even if it does work for hiding the start button) that it will prevent, as the OP wants, to users to launch applications ?
the windows+R keyboard combination allow the user to reach the "Run..." dialog, Windows+E keys, to launch the explorer...
i don't think this "security reason" should be solved like this...

I made an application which used a dll and loads it dynamically. If dll is not present an exception raises. All i want is if dll is not present it should be known at the Loadlibrary(..) call and i could handle that exception. I have specified lib fiel of that dll in the tools->project settings->link tab. Is there any other way?
Thank you

LoadLibrary() returns NULL if it can't load the DLL. If you're getting an exception, I bet you're not checking the return value from LoadLibrary() and blindly using it.

U lost.
I am checking the return value. Here is my code.
if((h = LoadLibrary("..\\Output\\DllOne.dll")) == NULL)<br />
{<br />
AfxMessageBox("Failed To Load Library");<br />
return;<br />
}<br />
COne one;<br />
one.ShowMsg();<br />
FreeLibrary(h);
Let me explaint what is happening exactly. My client application is a dialog based app. I wrote the above code in a button press. It should load and return value when button is presse.
But the problem is even the dialog is not being displayed. Even before that its showing the exception
"THE APPLICATION FAILED TO START SINCE ATHE one.dll IS NOT FOUND. REINSTALLING THE APPLICATION MAY FIX THE PROBLEM"
right after executing x.exe file.
Can u help me now?

This must not be using CAPS, for sure.
You must be be implicitely linking that dll, too. If you are using LoadLibrary, its not needed.
You need to use either of them.

Yes you are. From your first post:

That means implicitely linking to the dll. Remove that and all should be ok.
