In the book, it says:
the socket passed into ConnectEx needs to be previously bound with a call to bind.
Why does a client socket need binding?
|
|
|
|
|
Ummm - because that's the way the API works?
A socket is a communications endpoint - it needs an address (IP address and port number) before it can be used. For a client, the address is 'localhost' (or 127.0.0.1), whilte the port .
The Microsoft samples I've seen use the connect function rather than ConnectEx. connect doesn't require a bound socket - a bind (I would imagine) to an arbitrary port on localhost occurs within connect. ConnectEx gives a significant amount of flexibility in comparison - and (part of) the price for that would appear to be that you have to do the socket binding yourself.

Im unable to save a image using CImage. Im able to load and draw it. At a later stage, I need to save it to a different path, so I call Save(). It gives an error '80004005' "Unspecified error".
Please suggest..
TIA

Just now I tried the microsoft's sample. It also gives the same error.. I have nothing to debug. The HRESULT from save is E_FAIL. thats it. the file name is valid. I also tried giving it a simple path name such as "D:\\myImg", but the same error occurs.
TIA

Does GdiplusStartup succeed?

Could please post your code?

Nope. Just the relevant one.

I changed my code to use Image class.
I still have the same problem.
I open a image file. then try to save it in png format.
Save fuction returns "Win32Error" status.
GdiplusStartup is successful.
What may be wrong?

Can you show your code did you attach hbitmap handle to CImage class?

Another thing I noted is that if I give only the filename.jpg or png, it saves successfully, but if I give the whole path it fails with Win32Error.
|
|
|
|
|
When you use of filename.jpg it uses of current directory so I think your problem is of path.

Then probably either the path doesn't exist or you don't have sufficient rights to write to the path.

I have given "D:\\123\\123.png" as the path. The path exists and I have full control of the folder.
|
|
|
|
|
If you step into the Save method in the debugger, where is the error occurring?

In the CBitmap Save call. It returns Win32Error.
|
|
|
|
|
There shouldn't be a CBitmap::Save call....it should be a Gdiplus::Bitmap::Save call.

no code => no help.

How did you try like this:
m_Image.Save(_T("c:\\123\\image.jpg"));

Can you show your code for save and show how did you attach bithamp handle?

Hi,
doesn't Save need a second parameter to tell which format to use (JPG/PNG/...)?
Luc Pattyn [Forum Guidelines] [My Articles]
I use ListBoxes for line-oriented text, and PictureBoxes for pictures, not drawings.

It has a default argument.
If I dont pass, it will save it in a format identified by extension.
|
|
|
|
|
does that mean you got it to work? if so, how?
