Hello,
I am very new to Win32 Shell Programming. I am doing a simple project which needs me to select a folder from the hard-drive.
The following is small parts of the program:
1 : This is the "Brows For folders" calling part.
case IDC_BROWSE:
{
char buf[MAX_PATH];
BrowseFolders(hDlg, buf);
SendMessage(GetDlgItem(hDlg,IDC_EDIT1), WM_SETTEXT, 0, (LPARAM)buf);
return TRUE;
}2 : This is the BrowseFolders func with its accompanying CALLBACK.
int CALLBACK BrowseForFolderCallback(HWND hwnd,UINT uMsg,LPARAM lParam, LPARAM pData)
{
wchar_t szPath[MAX_PATH];
switch(uMsg)
{
case BFFM_INITIALIZED:
SendMessage(hwnd, BFFM_SETSELECTION, TRUE, pData);
break;
case BFFM_SELCHANGED:
{
TCHAR szText[MAX_PATH] = {0};
SHGetPathFromIDList(
reinterpret_cast<LPITEMIDLIST>(lParam), szText);
SendMessage(hwnd, BFFM_SETSTATUSTEXT, 0,
reinterpret_cast<LPARAM>(szText));
}
break;
}
return 0;
}
BOOL BrowseFolders(HWND hwnd, LPSTR lpszFolder)
{
BROWSEINFO bi;
wchar_t szPath[MAX_PATH + 1];
LPITEMIDLIST pidl;
BOOL bResult = FALSE;
LPMALLOC pMalloc;
if (SUCCEEDED(SHGetMalloc(&pMalloc)))
{
bi.hwndOwner = hwnd;
bi.pidlRoot = NULL;
bi.pszDisplayName = NULL;
bi.lpszTitle = L"Browse for folder";
bi.ulFlags = BIF_STATUSTEXT;
bi.lpfn = BrowseForFolderCallback;
bi.lParam = (LPARAM)lpszFolder;
pidl = SHBrowseForFolder(&bi);
if (pidl)
{
if (SHGetPathFromIDList(pidl,szPath))
{
bResult = TRUE;
strcpy(lpszFolder, (const char *)szPath);
}
pMalloc->Free(pidl);
pMalloc->Release();
}
}
return bResult;
}I have also tried this in place for BFFM_SELCHANGED :
if (SHGetPathFromIDList((LPITEMIDLIST) lp ,szPath))
{
SendMessage(hwnd, BFFM_SETSTATUSTEXT,0,(LPARAM)szPath);
}The problem is that the buf is filled with some garbage values. If I want to SETTEXT in an edit field, the buf data, I only get the first letter of the path selected. For ex: for C:/AAA/ , I get C followed by many little boxes(too many of them) .
I don't know what wrong I'm doing. Can anybody please help me in recognizing my fault for getting garbage values in buf!
Thanks in Advance
