You can't: a cast doesn't work magic, look for the real problem. The source type and the destination type are fundamentally incompatible. Looks like you’re compiling in Unicode but trying to work with ANSI strings: change your char to TCHAR and make sure you add #include <tchar.h> somewhere.

In addition to Stephen's reply, if you really need such a operation (i.e. passing a ANSI char string to a function accepting a wide char argument) the way to go is a string conversion, not a cast. For the purpose check out the WideCharToMultiByte documentation [^].

In addition to the two previous answers (yeah, that makes a lot of additions  ), I suggest this excellent article[^] if you want to understand how to work properly with strings in C++. It is a must read for all C++ programmer .

Seems the default constructor of the ConfigFile is just declared in the header file. check whether the ConfigFile::ConfigFile() function is written in the cpp file.

Hi Naveen,
here it is, it is written at the cpp file
ConfigFile::ConfigFile()
: myDelimiter( string(1,'=') ), myComment( string(1,'#') )
{
}
Thanks
|

Is this ConfigFile class in another dll or somthing? If not in a dll, check whether the the cpp file is added to the project or not?

dear all
after i debug my code, the erros displayed here: cannot convert parameter 1 from 'double [5]' to 'double'
how to solve this problem, anyone can give me suggestion. thanks

you are trying to assign an array to a double type variable. Iterate through the elements in the array and then you can assign the value at an index to a double type variable
BTW it would have been better if you could have posted the code snippet
Somethings seem HARD to do, until we know how to do them.

Hello,
does someone have information about creating iso files ? I think for the first time a normal iso file with an iso9660 system (so no joliet support or else) is enaugh, but i cannot find any useful information.
I get an information from ECMA but, it describes the format very bad and too easy. So i didn't find a right way to get into it.
Thanks for help.
bye,
gabbana

Perhaps start by looking here[^]. Note that I found this with a few simple Google searches.

Yes well thats an option but not suitable, because i want to do this on a lowel level.
My application will start writing iso images directly using SPTI and mmc commands. The problem with the imapi would be to produce special iso images. As the specifications say, i have some bytes at the beginning for free use before the image starts, and this is what i cannot do with the imapi i think.
So i need to do all the stuff by functsions like ReadFile,WriteFile...
Thanks.

Are there no other information available ? I spend about 2hours again searching different keywords with google without luck.
So if someony have an idea, please help me!

What's the error? Can you issue that command manually?

Can you check the values of "line" and "page" scroll in your control? It seems that it doesn't match, and that the control is not erasing the previous lines. BTW, a bit of your code (creation and/or both click messages) would be helpfull

Hello -
Does anyone know how an anti-virus software registers itself with windows (i.e. Windows recognizes valid anti-virus software in Security Center)? Is this done through the system registry, or monitored through reports in API calls? Any information would be helpful.
Thanks!

Hello,
i want to resize a loaded bitmap and i thought about to use
the windows method StretchBlt.
I can create a Bitmap out of a ByteArray and I can stretch it
according to the size of the window where it will be displayed
That's my way how i create a bitmap out of a bytearray.
you can see that i use StretchBlt.
CClientDC dc(pWnd);
CDC cdc;
CBitmap* pBitmap = NULL;
CBitmap* pOldBitmap = NULL;
cdc.CreateCompatibleDC(&dc);
dc.SetStretchBltMode(COLORONCOLOR);
::SetDIBits(NULL,hBitmap,0,dwHeight,pData,&Bitmapinfo,DIB_RGB_COLORS);
pBitmap = CBitmap::FromHandle(m_HBitmap);
pOldBitmap = cdc.SelectObject(pBitmap);
if(bStretchMode)
{
dc.StretchBlt(rect.TopLeft().x,rect.TopLeft().y,rect.Width(),rect.Height(),&cdc,0,0,m_iSrcWidth,m_iSrcHeight,SRCCOPY);
}
else
{
dc.BitBlt(rect.TopLeft().x,rect.TopLeft().y,rect.Width(),rect.Height(),&cdc,0,0,SRCCOPY);
}
cdc.SelectObject(pOldBitmap);
ReleaseDC(&cdc);
cdc.DeleteDC();
Now what I want is to load a bitmap from file, resize it and get a pointer
to the bytes of this resized bitmap. i dont need ti display the loaded
bitmap. the loaded bitmap is a binary bitmap,just black and white.
I load the image with this code
HBITMAP hBmp = (HBITMAP) ::LoadImage(NULL,
filename.GetBuffer(),
IMAGE_BITMAP,
0, 0,
LR_LOADFROMFILE |
LR_CREATEDIBSECTION);
BITMAP BM;
GetObject (hBmp,sizeof (BM),&BM);
CBitmap* pBmp = CBitmap::FromHandle(hBmp);
So, any suggestions ?
greetings,
cmos

Yes.
Maybe
Create a second DIBsection, the size and bit-depth you want
Create a memory DC
Select the DIBSection into the new DC
StretchBlt the source bitmap to the memory DC, just like in your code above
