The SHCreateDirectoryEx function.

[iMikki]

Hi guys, Here I am again... But now with another problem :p SHCreateDirectoryEx(NULL, "c:\\text", NULL); gives me the following error:

1>d:\app2\app2\Form1.h(302) : error C2664: 'SHCreateDirectoryExW' : cannot convert parameter 2 from 'const char [8]' to 'LPCWSTR'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

I found that _T("..") should work; giving me the following error:

1>App2.obj : error LNK2028: unresolved token (0A000028) "extern "C" int __stdcall SHCreateDirectoryExW(struct HWND__ *,wchar_t const *,struct _SECURITY_ATTRIBUTES const *)" (?SHCreateDirectoryExW@@$$J212YGHPAUHWND__@@PB_WPBU_SECURITY_ATTRIBUTES@@@Z) referenced in function "private: void __clrcall App2::Form1::saveButton_Click(class System::Object ^,class System::EventArgs ^)" (?saveButton_Click@Form1@App2@@$$FA$AAMXP$AAVObject@System@@P$AAVEventArgs@4@@Z)

1>D:\App2\Debug\App2.exe : fatal error LNK1120: 2 unresolved externals

Does anyone have experience with this function. I want to make a (n absolute) folder and the OS where this will be written for is Vista (sorry - I might upgrade to W7 tho). Could someone give me some hints? Kind regards,

Try referencing shell32.lib in Additional Dependencies option of the project Linker properties. If you're doing a C++/CLI application, you should be using Directory::CreateDirectory instead.

I got an application. So called Windows Forms Application. I will try Directory::CreateDirectory. Thanks again. ---------- Edit: The IDE (Visual C++ Studio 2008 Express) cannot find Directory::CreateDirectory. I might to include some file I guess... ---------- Re-edit: CreateDirectory("c:\test", NULL); works... Sort of - now I get the following error:

1>d:\app2\app2\Form1.h(304) : error C2664: 'CreateDirectory' : cannot convert parameter 1 from 'const char [7]' to 'LPCTSTR'

You need to tell me if it is a managed or unmanaged application. Do you see using namespace xxx or #include xxx on the top of the file? And what are they?

CreateDirectory(_T("c:\\test"), NULL);

#include <shlobj.h>
int main(){
SHCreateDirectoryEx(NULL,"c:\\jinx",NULL);
return 0;
}

tested it with ms vc++ 2008. it works like charm :)
