I have a Check Box in a dialog, I set "Disabled" as "True" in its properties. How can I enable it after I click a event handler during the program executing? If I want to disable it again, how can I do it?
What about a Radio Button? same way?
Thanks,
Joy Anne

GetDlgItem(IDC_YOURCHECKBOX_ID)->EnableWindow(TRUE);

Just for the records:
Calling GetDlgItem is extremly bad style!
For enabling/disabling items in a program, you use the
ON_UPDATE_COMMAND_UI(IDC_YOURCHECKBOX_ID, OnUpdateYourCheckbox) idiom.
If you really need to manipulate the IDC_YOURCHECKBOX_ID-control, make a control variable and use this (as described by WhiteSky).

I don't think so. What are the reasons?

Well, my statement may have come across a bit too strong.
But I believe that, in an object oriented environment, ou should use the object oriented way to do something.
By using the ID_SOMETHING resource constants directly, you are breaching confidentiality of the inner workings of the control-class.
You are working 'across' the MFC mechanisms, which I view as a bad thing when you have decided to use MFC.

No. I just wanted to know.

True.

Well GetDlgItem(ID...) returns a pointer to a CWnd object. I don't see any breach here.

This is still MFC because it returns a CWnd pointer.
Well some advocate against using GetDlgItem but I personally like it.
Have you ever had problems with GetDlgItem, well I never had. I you had let please me know.

 I know I just finished an adult beverage but I am clueless why exactly you posted this here. Is this an answer to a question that someone posted? Or did codeproject somehow mess up??
[EDIT]
Ok, I think I know what you want. You are asking how to read in data like this line by line and store the last data into a 3 dimensional array...

You could be doing something wrong.

I try to add following code in afxThread:

Can i pass out the value or call back the function outside the afxThread ?
Thanks

AddLog is a member function and you are accessing it as if it is a static member function.
Create an instance of CTestingDlg and then access AddLog.
Note: You will get better answers if you can post this question to the author of this article.

Hi,
This is how you should use your thread:
AfxBeginThread(YourThreadName , this);
Now , in your thread :
UINT YourThreadName(LPVOID lpvoid)
{
YourClass *dlg = (YourClass *)lpvoid;
dlg->AddLog("Hellow");
}
Regards,
Eli

I want to extract the icon of any file or folder .Earlier I solved this portion of treeview in vb.net using the implementation of the following API's. I want to know the implementation in VC++ 6.0
Private Declare Auto Function SHGetFileInfo Lib "shell32.dll" (ByVal pszPath As String, _
ByVal dwFileAttributes As Integer, ByRef psfi As SHFileInfo, ByVal cbFileInfo As Integer, _
ByVal uFlags As Integer) As IntPtr

It's the same. Loop up MSDN for SHGetFileInfo for more details.

Can I get the link for my Query in vc++ 6.0 ?

SHFILEINFO shfi;
memset(&shfi,0,sizeof(shfi));
SHGetFileInfo("somebmpfile.bmp",
FILE_ATTRIBUTE_NORMAL,
&shfi, sizeof(shfi),
SHGFI_ICON|SHGFI_USEFILEATTRIBUTES
);
shfi.hIcon;

The Problem is when I right click on the node the selection goes to previous selected node.

That's how tree behaves. Left click result in selection. Right click doesn't, previous selection gets selected again.
You can use HitTest to select the particular item.

Is there any function that selects the node on right click

Handle NM_RCLICK...
Use HitTest to select the item.
