Hi again.
I came with my app to the point where I need to stage an image for CD record! But error occure once again.
I'm obviously doing something wrong in my code. Here it is:
...<br />
IStorage* pStorage = NULL;<br />
IStream* pStream;<br />
int i=0;<br />
StgCreateDocfile( NULL, STGM_DIRECT|STGM_CREATE|STGM_READWRITE|STGM_SHARE_EXCLUSIVE, NULL, &pStorage);<br />
<br />
CFile files[32];<br />
<br />
POSITION pos = filenames.GetHeadPosition(); <br />
while(pos != NULL)<br />
{<br />
CString strFilePath=filenames.GetNext(pos);<br />
<br />
int nSize = 0;<br />
CFileException e;<br />
<br />
if (filesIdea.Open(strFilePath,CFile::modeRead|CFile::typeBinary,&e))<br />
{<br />
LPWSTR lpszW = new WCHAR[255];<br />
LPTSTR lpStr = strFilePath.GetBuffer( strFilePath.GetLength() );<br />
int nLen = MultiByteToWideChar(CP_ACP, 0,lpStr, -1, NULL, NULL);<br />
int code = MultiByteToWideChar(CP_ACP, 0, strFilePath, -1, pszW,nLen);<br />
if(!code)<br />
{<br />
CString tmp = _T("'MultiByteToWideChar' returns NULL!");<br />
DWORD err = GetLastError();<br />
DisplayErrorString(tmp,err);<br />
if (lpszW)<br />
delete [] lpszW;<br />
filesIdea.Close();<br />
pDiscMaster->ClearFormatContent();<br />
return FALSE;<br />
}<br />
<br />
HRESULT res;<br />
if( (res = pStorage->CreateStream( lpszW, STGM_DIRECT|STGM_CREATE|STGM_READWRITE|STGM_SHARE_EXCLUSIVE|STGM_FAILIFTHERE, 0, 0, &pStream) ) != S_OK )<br />
{!!!HERE IT'S CRACKS SAYING "Invalid value for pwcsName." (lpszW???)<br />
ShowHRError(res);<br />
if (lpszW)<br />
delete [] lpszW;<br />
filesIdea.Close();<br />
pDiscMaster->ClearFormatContent();<br />
return FALSE;<br />
}<br />
nSize = files[i].GetLength();<br />
BYTE *pBuffer = new BYTE[nSize];<br />
if (files[i].Read(pBuffer,nSize) > 0)<br />
{<br />
pStream->Write(pBuffer,nSize,NULL);<br />
pStream->Release();<br />
}<br />
files[i].Close(); <br />
delete[] pBuffer;<br />
}<br />
<br />
...
I'm trying to find code example which works?? Or someone who can tell me where I did wrong??Why can't I create stream, what is wrong with lpszW
THX to all

for (int i = 0; i < m_List.GetItemCount(); i++)
{
SetCheck(i, FALSE);
}

did you mean:
for (int i = 0; i < m_List.GetItemCount(); i++)
{
m_List.SetCheck(i, FALSE);
}
didn't you?

The code that Hans showed could have been placed in a CListCtrl-derived class.

Connect to the database, read the strings from it and then use CComboBox::AddString to add the strings in the combo box.
Somethings seem HARD to do, until we know how to do them.

I think you need to MFC and MySQL[^] (MFC classes to fill ComoBoxes & ListBoxes with MySQL data.)
|
|
|
|
|
call AddString() function to add data.

 Hi,
I am using Visual studio 2005 for my application.
In my application,Loadlibrary is used,
LoadLibrary("library.dll");
If i simply give like this, it's showing error as "cannot convert parameter 1 from const char to LPCWSTR",so i typecasted it as,
LoadLibrary(_T("library.dll"))
or
LoadLibrary((LPCWSTR)"library.dll"))
if i give like this it is not taking or recognizing the library gives error as No such lib found.
Please I need help...

This is because in your project setting the _UNICODE is defined. So you must specify unicode string like LoadLibrary(_T("library.dll")) or LoadLibrary(L"library.dll").
siddharthsan wrote: LoadLibrary((LPCWSTR)"library.dll"))
This is not the corrcect way. This casting dosent make the string unicode.
siddharthsan wrote: library gives error as No such lib found.
This error may be because the dll is not in the path.
try
1.Give full path of the dll in that function.
2.Add the path of the dll into the "PATH" environment variable. Restart msdev after this and try

So the compiler is wrong and and you are making it listen by casting, right!!

Siddharth,
Have you tried using LoadLibraryA("library.dll")? Your project is clearly set to use UNICODE by default and the API headers are defining LoadLibrary as LoadLibraryW. This is a bit of a strange one, I've never been quite sure what happens if you try to load a dll with the name in UNICODE (wide characters).
Note: ((LPCWSTR)"library.dll") will never work as this just casts the pointer to narrow string to a pointer to wide string but doesn't change the string
If LoadLibraryA does not work then I guess it just can't find your dll. Is it in the normal search path, i.e. same dir as exe or Windows\System32 or somewhere mentioned in the PATH environemnt variable?
Nothing is exactly what it seems but everything with seems can be unpicked.

Try a fully-qualified path.

This is wrong. If you get into the habbit of using static_cast instead of C-style casts this kind of mistake will produce compiler errors instead of runtime errors.

Use PreTranslateMessage()

You should write some code to read from .doc file and then write the strings read into the database.
Then, Post a specific problem that you are stuck on and some one here will help you out.
