• rodri_ogri SetCheckboxValue method

  Hi, When i try the SetCheckboxValue method i get a compile error saying identifier not found... This is the actual code i get the error at: SetCheckboxValue(IDC_mycheck, true ); Any ideas Cheers Anger. Hi. I think that you use an Interface "ICredentialProviderCredential::SetCheckboxValue Method" for Set checkBox; that exists in WinSDK. http://msdn.microsoft.com/library/default.asp url=/library/en-us/shellcc/platform/shell/reference/ifaces/icredentialprovidercredential/setcheckboxvalue.asp for use this Interface you must initialize a COM.  like this : #include "Windows.h" #include "wininet.h" #include "shlobj.h" using namespace std; int main() {  HRESULT h ...Show All

• tantz <windows.h> Interferes with System::IO::Directory::GetCurrentDirectory();

  Including windows.h in a managed project overrides System::IO::Directory::GetCurrentDirectory();, which is very annoying: rootFolder = System::IO::Directory::GetCurrentDirectory(); //'GetCurrentDirectoryW' : is not a member of 'System::IO::Directory' How can this be prevented This seems to be the only function in wondows.h that gets confused with System::... I didn't know such a thing could be done. It works, thank you. If you do not need the GetCurrentDirectory function from windows.h , maybe you can just un-define it: #include <windows.h> #undef GetCurrentDirectory I hope this makes sense. ...Show All

• Anarchy CreateThread vs _beginthreadex

  Hello. There is a hot discussion on one Russian developers forum about correct threads creation. _beginthreadex is more correct way because it initializes CRT for the newly created thread. But there is one great "BUT"!!! For example we have any callback function which uses CRT (like an exported function from dll). This function could be invoked from any thread including threads, that was created via CreateThread (i.e. CRT was not initialized for this thread). So this call can cause an undefined behaviour! But there is not way to determine CRT initialization status and initialize CRT manually It looks like a potential source of great troubles. Simple Samples wrote: Alexander Stoyan w ...Show All

  Hi: I want to know how to intercept the event which is generated when the user do : CTRL+X or a paste. I don't find a message like SC_PASTE in the documentation.

• Scott_P basic_ostream::write() formatting bug

  I called the basic_ostream<char> method write(const char_type*, streamsize); and the function seems to be formatting the data I'm sending it. In my case, I sent it a double with the byte values: 0x9d, 0x16, 0xe7, 0xc6, 0xb4, 0x0a, 0xb7, 0x41 but what ended up in my file was: 0x9d, 0x16, 0xe7, 0xc6, 0xb4, 0x0d, 0x0a, 0xb7, 0x41 Looks like the write function interpreted a byte of my double as a '\n' and converted it to a '\r' '\n' pair. This would be correct except that write is an unformatted output function and should not do any conversion - regardless of the open mode's binary flag. (see book "Standard C++ IOStreams and Locales - ISBN 0-201-18395-1", p51 for details on the C++ standard). Two action items ...Show All
