Hello guys,

Is there any API, which will return the full path of the folder from where my application is running ?
Like GetModuleFilename() API , - but it returns the fullpath , including the filename.

thanks

Hi You can extract Path easily, Like

GetModuleFileName(NULL,m_CurrentPath.GetBuffer(512),512);<br />
m_CurrentPath.ReleaseBuffer();<br />
m_CurrentPath.Delete(m_CurrentPath.ReverseFind('\\'),m_CurrentPath.GetLength()-m_CurrentPath.ReverseFind('\\'));

PathRemoveFileSpec Function
Removes the trailing file name and backslash from a path, if it has them.

BOOL PathRemoveFileSpec(LPTSTR pszPath);

as Blake Miller explained, PathRemoveFileSpec() exists for that but hey, look, it certainly does what one presented you before (with the reverse string search), and calling it will only slow your prgram down because of an added function call...

Slower compared to what?

compared to when you do the same thing without a function call...

Hi Giorgi,
AFAIK, There is no such Api to Reterive Folder name only, you have to manually parse the FolderName ! Smile | :)

File is open or read only.

Hi,

Well was that file open (while deleting ),check for the file attributes ( the file is a read-only file, the function fails with ERROR_ACCESS_DENIED.
),this is all i could think at the first shot .

The file is in use. Use Handle to determine what process has it open.

WM_DROPFILES in a system defined "EDIT" window

I am creating an application where the user will need to define the location of two files. To make it easyer I want to give them the option to drag and drop the file onto the child window editbox system defined class. The problem is that the edit box will only handle the built in messages and passes all others onto DefWindowProc, including WM_DROPFILES. Any Ideas how I can make this work?

Has that window registered itself as a recipient of dropped files?

Yes it has, when run I can pick up a file and move it over the edit box and the curser changes to the drop file curser. The problem I am having is not being able to define the callback function for the system defined window class, or tell it to forward messages it doesnt handle someplace else where I can define what it does.

Do you have something like:

LRESULT CALLBACK WindowProc(...)
{
    switch (uMessage)
    {
        case WM_DROPFILES:
            HDROP hDrop = (HDROP) wParam;
            char szDropName[MAX_PATH];
            DragQueryFile(hDrop, 0, szDropName, sizeof(szDropName));
            break;
        default:
            return DefWindowProc(hWnd, uMessage, wParam, lParam);
    }
 
    return 0;
}

how explorer launches control panel

I came across this cool link that tells me how to run various control panel activities from the command line. I wonder how windows exlorer itself runs them? I dont see windows explorer doing "CreateProcess" for any of these. Any idea how windows explorer launches control panel or the run dialog box?

I am planning to use this in an application that will basically prevent kids from launching control panel while I take a break from the computer Smile | :)

thanks

I think you did not get my point. I tried using a few api intercepting tools and I dont find windows explorer calling CreateProcess here. That is why I am wondering how it launches control panel?

Any shell experts around here?

thanks
