I have an MDI program. One of the dialog boxes carries out some calculations and writes them to a file. I would like the program to open the file automatically. The file name will be known. The user defines it in the dialog box.
Thanks
I feel more like I do now than I did awhile ago.

This is a basic operation with iostreams - I have articles on CP, the MSDN has info also, as does google.

The MDI program is a text editor. I would like the file to be visable as if the user had opened it with the file open dialog box. Is this still covered with IOstreams?
|
|

|

Absolutely - an ifstream will read your file in no worries, and then you can just set up your editor to contain the data read in.
something like
std::ifstream a(szFilename);
std::string s;
while (getline(a, s))
MyInternalBuffer += s.c_str();
You need to include string and fstream for this to work.

How do I set up the editor to contain the data? that is where i am having problems. I have no problem reading the data into the buffer.
I thought maybe I could
CMyDoc* pdoc;
pdoc.OpenFile( CString path );
I have searched my books on Doc/View architecture. I am sure the answer is there but I don't see it.
Thank You

Oh - the problem is not loading, it's actually having the text in the editor ? There are many ways to go about this, the simplest is to use a CEditView ( from memory ) and call SetWindowText on it.

Has anybody tried to put a bitmap background on a CRichEditView?
I've tried to use GetRichEditCtrl().ModifyEx (0, WS_EX_TRANSPARENT) and it did give me a transparent background CRichEditCtrl. However, I can't paint the background of the view!
How come ON_WM_ERASEBKGND message is NOT sent to the CRichEditView?
Any help will be appreciated.
Thanks,
Duc Truong

Hi.
I am very close to finishing an IOCP Winsock program. However, there is one major bug that I have not been able to debug and determine a working solution. One reason is the fact that I do not know what causes this bug. Note that this now the only bug or at least the only one that Visual C++ Debugger finds.
Here is the message from the debugger.
-----
HEAP[Program.exe]: HEAP: Free Heap block 36a9c8 modified at 36a9f4 after it was freed
Unhandled exception at 0x77f7f570 in Program.exe: User breakpoint.
-----
I notice that the program crashes and Visual C++ Debugger outputs this message only when the IOCP handles multiple sockets. I do not have an accurate count, but I believe ten or more sockets will cause the program to crash. To my understand, IOCP can handle thousands of sockets. In fact, a working WSAAsyncSelect I/O model of this same program works great under hundreds of sockets at any given time.
In terms of IOCP, what could be some causes of this heap problem?
Thanks,
Kuphryn

It seems that the problems you have do not have anything to do with IOCP. It appears to be a buffer overrun or, more probable, calling delete two times on the same pointer.

Good point. Thanks.
I will check all pointers and allocations and deallocations.

Data that exists in CTreeCtrl and can be got by GetItemData is for what ? Is handle of each tree Item not enough? ( HTREEITEM)When should I use GetItemData ?

you should use GetItemData when you've already used SetItemData to put set data into the item. it's just a place for you to store something.

The list control supports background images. See the docs for LVM_SETBKIMAGE

Hello everyone,
I am writing a http server, and I can not make the decision whether using blocking socket or noblocking socket. Not long ago I finished a trial edtion with nonblocking socket in a single thread, but I found it is not very efficient, so I am rewriting it using multithreading mode. I puzzle about which kind of socket get a better efficiency.
Who has the experience please give me some advices, my server will transmit about 150kb per response, and I can not identify the amount of responses per second, my server will run at a 100M network.
thanks.

The best performance will be achieved by using from 1 to 4 threads per processor, and Overlapped I/O for transmitting dynamically generated pages.
But if what you need is a high-performance file transfer for your HTTP server, you could use the TransmitFile API function. It has the best sustained data trasnfer rate available.

Does anyone know why my CComboEx on a dialog, which has images on it, doesnt work right? You can scroll through all of it's contents with the arrow keys, but when you try to use the mouse to click the little down arrow to make the options drop-down nothing happens? Thanks...

have you sized the drop-down space on the resource editor? the default is a drop down of zero-height (i don't know why).
