c++ - Bad pointer or link issue when creating wstring from vc6 dll -

-

I got a DLL using VC6 and using wstring , and I use it In a VC9 project I am trying to do this DLL has a high level class named wstring , UtfString .

Everything was properly imported into my project, but when I call: 

  std :: wstring test; UtfString uTest (test);

This will not be a link, even if the function prototype is in Lib ...

The other issuer is that when creating a new UtfString, and debug my app, New pointer & lt; Bad Ptr & gt; .

I do not believe VC6 wstring and VC9 wstring I want to avoid refining the original DL.

It would be great if someone can make things more clear to me, and what is the real reason of the problem to explain to me.

Thank you in advance for your answer, Boris

Do not even try < / P>

String layouts are different

You can not do this

The string class is completely different between VC6 and VC9.

Even if you were able to link, you would most likely be the accident.

There is a union in the VC9 string which is an indicator for 16 byte buffers and string for small string s.t. Size ()> 15 VC9 has a union in whiteness, which is an indicator STT for 8 watcher buffers and string for small wires. is. Size ()> 7

All string buffer space in VC6 is allocated on a pile.

If you pass strings across boundaries, then you have to compile the DLL again.

sorry that will be rebuilt

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
