Is m_hBitmap NULL after the CreateDIBSection call?
"If you can dodge a wrench, you can dodge a ball."
|
|
|
|
|
m_hBitmap is not NULL, and I can display it ok, but GetLastError() = 87, INVALID_PARAMETER. I don't know why?
|

If it's not NULL then it was successful and calling GetLastError() isn't necessarily valid.
You only need to call that on failure.
From the docs:
"Most functions that set the thread's last-error code set it when they fail. However, some
functions also set the last-error code when they succeed. If the function is not documented to
set the last-error code, the value returned by this function is simply the most recent last-error
code to have been set; some functions set the last-error code to 0 on success and others do not."
Generally errors are checked for and handled something like:
m_hBitmap = CreateDIBSection(hdc, &bmpInfo, DIB_RGB_COLORS, &pBits, m_hMMF, dwOffset);
if (NULL == m_hBitmap)
{
TRACE("Error code = %d \n", GetLastError());
...do appropriate error handling/cleanup here
}
"If you can dodge a wrench, you can dodge a ball."

I am trying to write a GINA, but am faced with a problem... I need to retrieve some info over the internet/intranet. Does anyone know if this is possible, if so how would I go about it? 
I have samples of writing a GINA, but all point to simply adding the password either from biometric readers or smartcards, I need to fetch a template over the net, scramble it and present it to the logon user (in a webpage).
Any ideas?
Thank you,

 Hi,
I want to read RTF file in Chunk by chunk.
And I want to append in StreamIn i.e. RichEditCtrl.
But Chunk by chunk upending is not working. If I read
whole file in buffer and append/insert, it works fine.
I set SF_RTF and SFF_SELECTION flags for StreamIn.
If anyone knows about RTF & RichEdit control,
please help me.

Is there a reason you are using SFF_SELECTION? Are you reading an entire file/stream to fill
the richtext control or appending/replacing existing text in the control?
What isn't working? Does your callback get called?

Use WIN32_FIND_DATA,FindFirstFile(),FindNextFile(), you can write a recursive function.

Like this ??
WIN32_FIND_DATA mystruct;
mystruct.dwFileAttributes = FILE_ATTRIBUTE_DIRECTORY;
HANDLE myHandle = FindFirstFile("C:\\<dirMain>\\subdir", &mystruct);
BOOL myBOOL = FindNextFile(myHandle, &mystruct);
DWORD bw = GetLastError();
18 There are no more files. ERROR_NO_MORE_FILES
It doesn't work ??

Set up the search with ::FindFirstFileEx() and limit the search to directories.
Call ::FindNextFile() until the call fails, i.e. returns FALSE and ::GetLastError() returns ERROR_NO_MORE_FILES.

I have tried the following, but I can't seem to get it right.
All I want is to get all the names of directories and not the files.
Can someone please help me???
HANDLE Handle;
WIN32_FIND_DATA FindData;
char Temp[256];
char tempBuffer[100];
sprintf((char *)Temp, "C:\\dirMain\\subDir");
Handle = FindFirstFile((char *)Temp, &FindData);
while(1)
{
if(FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
printf("Dir Name : %s\n",FindData.cFileName);
}
else
{
break;
}
if(!FindNextFile(Handle, &FindData))
break;
}
Many Thanx

This works:
void ChangeDirectoryAttribute(TCHAR* m_szFdPath)
{
HANDLE hFile;
WIN32_FIND_DATA FileInformation;
TCHAR m_szPath[MAX_PATH];
TCHAR m_szFolderInitialPath[MAX_PATH];
TCHAR wildCard[MAX_PATH] = "\\*.*";
strcpy(m_szPath,m_szFdPath);
strcpy(m_szFolderInitialPath,m_szFdPath);
strcat(m_szFolderInitialPath,wildCard);
hFile = ::FindFirstFile(m_szFolderInitialPath, &FileInformation);
if(hFile != INVALID_HANDLE_VALUE)
{
do{
if(FileInformation.cFileName[0] != '.')
{
strcpy(m_szPath,m_szFdPath);
strcat(m_szPath,"\\");
strcat(m_szPath,FileInformation.cFileName);
if(FileInformation.dwFileAttributes &
FILE_ATTRIBUTE_DIRECTORY)
{
::SetFileAttributes(m_szPath,FILE_ATTRIBUTE_NORMAL);
printf("Dir name: %s\n", m_szPath);
ChangeDirectoryAttribute(m_szPath);
}
else
{
::SetFileAttributes(m_szPath,FILE_ATTRIBUTE_NORMAL);
}
}
}while(::FindNextFile(hFile, &FileInformation) == TRUE);
::FindClose(hFile);
DWORD dwError = ::GetLastError();
if(dwError == ERROR_NO_MORE_FILES)
{
}
}
}
int _tmain(int argc, _TCHAR* argv[])
{
TCHAR m_szFolderPath[MAX_PATH] = "C:\\Program Files\\MyFolder";
ChangeDirectoryAttribute(m_szFolderPath);
return 0;
}

Kinda hard to get those functions working like one wants too.

Only if you live in a cave with no Internet access. Googling for FindFirstFile() yields more examples than you can shake a stick at.

I am a Newbie. I want to know how can I send HTTP request, both GET and POST using vc++. What are the libraries needed for that. And how can this be incorporated in a DLL.
This is urgent. So please reply faster.
Thanks for your prompt reply.

Yes Sir,
Read MSXML interfaces....
Think about forming requests and getting the response. Deserialize the response and you are done. That is all to it.
