That is some dumb way of doing things. What if you have a 14 folders intermediate to create the innermost folder? Use SHCreateDirectory() or SHCreateDirectoryEx() instead.

SHCreateDirectory(NULL, TEXT("D:\\Hi there\\Good luck"));

Hi brahmma,

I am getting undeclared identifier, we have to include any header or lib file ???

SHCreateDirectory(NULL, TEXT("C:\\A\\B\\C"));
SHCreateDirectoryEx(NULL, TEXT("C:\\A\\B\\C"));

error C2065: 'SHCreateDirectory' : undeclared identifier
error C2065: 'SHCreateDirectoryEx' : undeclared identifier

#include "shlobj.h" and you need to link to shell32.lib

I think you need to download the latest Platform SDK.

You need to download latest platform SDK. If its already there. Update include directories settings for your IDE, to point to updated SDK.

In addition to my previous reply.
Mentioned API's are available with IE version 6 onwards. Make sure sure it is present on your machine.
And to compile youe code , your need to update IE version in your app,
too.

#ifdef _WIN32_IE
#undef _WIN32_IE
#endif
#define _WIN32_IE 0x0601

Use above line of code in your application. Before including concern API file.

~~SHCreateDirectoryEx(NULL, TEXT("C:\\A\\B\\C"));~~ There is a third parameter to the Ex version of this function!

Did you not even look at this function in the documentation? the Ex version of this function allows you to define security attributes to the folder that you create. That is the third parameter while using the Ex version and that is the only difference between SHCreateDirectory() and SHCreateDirectoryEx(). If you do not want to define security attributes, then do not use the Ex version.

I just tried with both the options, I want just to create a set of folders c:\\a\\b , then I think SHCreateDirectory() is enough.

Tree View Control with Checkbox

if I give char buf[ ] = “C:\\A\\B\\”; this code has no effect .

Path up to parent directory should be valid to make call to CreateDirectory succesfull. In your case,
folder 'A' should be present to create folder 'B' in it.

hi i need help in the case of Tree View Control with Check Box.

my problem is whenever i select a check box and click close/cancel(within the dialog box) and come back to check box selection i need the previous tree state
to be retained,ie if i selected "parent1" and closed it when i come back again to the dialog box i will get the new dialog where previous state is lost.

status should be retain till the end of the close of main window.
here is the code with which i am trying . but it dint work

/*if(PreviousCheckStatus)
{
TVITEM item;
item.mask = TVIF_HANDLE | TVIF_STATE;
item.hItem = hParent1;
item.stateMask = TVIS_STATEIMAGEMASK;
item.state = TVIS_SELECTED ;
SendDlgItemMessage(hWnd,IDC_TREE1,TVM_INSERTITEM, 0, (LPARAM)(&item));
}
*/

What does this line mean? Whether the global variable is not showing the prev status or the control on the dialog?
If 'the control' is ur answer then ... are u setting the control according to the value of your global variable in the dialog's OnInitDialog()?

i am checkin the global variable in WM_INITDIALOG.just for the sake of testing one global variable is being maintained for each checkbox.if the variable has true value, then trying to set the corresponding checkbox as selected.

when i run the app for the first time, obviously the global variable will have value 0.
consider i select a check box(corresponding global variable is True now).i ll close the dialog n open it again.here that peice of code i given above is not working.
could u get me ur mail id so that i can send u the complete program ??
