automate an already-launched visual studio IDE ppp00120-Mar-07 8:00 ppp001 20-Mar-07 8:00  Hi, How can I get the reference of a already launched visual studio IDE in the Window OS and automate it in my program ? Thanks Common Controls 6 and porting from VS2003 to VS2005 Christopher Duncan20-Mar-07 7:02 Christopher Duncan 20-Mar-07 7:02  Hey, guys. I have a dll that I originally built in VS2003 that uses the new common controls 6 look and feel via jumping through the hoops of the manifest, defining ISOLATION_AWARE_ENABLED and such. I opened and converted this project in VS2005. Everything compiles, everything works, except that I no longer get the cc6 look and feel. Anyone have any idea what it is about VS2005 that breaks this, and how I can fix it?

Good Bye (Full name of the project is -> CRoundButton2 - A fancy graphical button) Re: owner-drawn button toxcct20-Mar-07 7:12 toxcct 20-Mar-07 7:12  the best place to ask is in the forum at the botton of the article from which you downloaded it.

I figured id repost this in the right forum to see what you guys thought. Im having a problem with the CImage::GetBits(). Im opening a TIFF file using a CImage object, and i want to take information from this image for use in another function. Here is whats happening. unsigned BYTE* pBits<br /> chBitBuffer = /*the image*/image->GetBits(); This compiles, and appears to work fine, but after several access violations I went a bit deeper. image's height = 1179, width = 673, bits per pixel = 32. So Im assuming that the number of pixels = height * witdth. Number of pixels * 4 = total number of bytes, since each pixel is 4 bytes (32/8). The problem comes in when I try to access the data returned from GetBits(). The buffer only has a length of 3224 in this example, when my calculations say it should be as long as the number of bytes(3173868). Any clues to what may be going on here? I win because I have the most fun in life... Re: CImage Woes Dave Calkins20-Mar-07 5:44 Dave Calkins 20-Mar-07 5:44  The individual rows of pixels aren't necessarily right next to each other in memory; chances are there are padding bytes at the end of each row of pixels; Look at the GetBits() and GetPitch() documentation for info on this. Also, depending on the pitch your pointer may be pointing near the end of the image not the beginning. When you say, "The buffer only has a length of 3224", which buffer are you referring to? How are you getting this size? Re: CImage Woes VonHagNDaz20-Mar-07 5:53 VonHagNDaz 20-Mar-07 5:53  GetPitch() returns a -2692, which mean the DIB is bottom up. this means that the buffer pointer is pointing towards the last row of the image. the buffer is the bitmap buffer that GetBits() returns the pointer to. I got the 3224 with a dumb for loop to see when i got the access violation. for(int i = 0; i < 999999999; i++) nBits[i] = o; it broke on i = 3224 I win because I have the most fun in life... Re: CImage Woes Mark Salsbery20-Mar-07 8:47 Mark Salsbery 20-Mar-07 8:47  The fact that it faulted at 3224 is arbitrary. There may have been extra bytes allocated for alignment or efficiency or whatever. That doesn't mean it's ok to read/write past the end of where the data is supposed to be. Mark "Great job, team.

Client Socket and connection problem nahitan20-Mar-07 4:25 nahitan 20-Mar-07 4:25  Hi there, I was wondering if you have a client socket that is supposed to initiate the connection to a server, how often the client sends the request? I have a client socket and it seems that there is some wireless communication problem so that the socket connection to the server goes down and the client socket sends the request for connection every 1/100 second. Does it make sense to you guys? I log every messages that go through the sockets and I see the connection request every 1/100second and it seems that the connection is establishing and then I see WSAENOTSOCK message and the socket gets closed and the establishes and I get WSAECONNRESET message and it continues until the connection stays up and open. Does anybody know whatis going on here?? Thanks, Re: Client Socket and connection problem Mark Salsbery20-Mar-07 8:57 Mark Salsbery 20-Mar-07 8:57  It depends on the protocol. If you're using TCP then you could research the TCP protocol and see how it handles reconnects. I suppose that could be implementation specific - Microsoft's TCP implementation may be different then others. How are you seeing the socket error codes? These aren't part of the protocol. The WSAENOTSOCK error isn't good - that's usually (always?) from a programming error. Mark "Great job, team. Head back to base for debriefing and cocktails." (Spottswoode "Team America") Re: Client Socket and connection problem nahitan20-Mar-07 9:18 nahitan 20-Mar-07 9:18  I have done this t get the Error: BOOL Socket::StoreError( INT Error ) { BOOL RetCode; RetCode = FALSE; __try { if( Error != 0 ) { ......... switch( Error ) { case WSAEACCES: wsprintf( ErrBuff, "WSAEACCES" ); break; case WSAEADDRINUSE: wsprintf( ErrBuff, "WSAEADDRINUSE" ); break; case WSAENOTSOCK: wsprintf( ErrBuff, "WSAENOTSOCK" ); break; ........... ........... if(( strlen( ErrBuff )> 0 )&&( RetCode )) { LogError( "Socket", "StoreError", "%s, %s", sName, ErrBuff ); } I also check the status of the socket in the data link layer and write it down to the log. Re: Client Socket and connection problem Mark Salsbery20-Mar-07 9:23 Mark Salsbery 20-Mar-07 9:23  Ok, but what calls this Socket::StoreError() method? If you are getting a WSAENOTSOCK error somewhere then that means a socket op is being attempted on a handle (SOCKET) which isn't a known socket. Not good "Great job, team.

Let say my socket is connected to the server 2. I turn off the wireless link of my computer and there should be no socket connection. 3. Neither client socket nor server socket understand that the connection is gone until I re connect the wireless switch in my computer and get connected to the network, at that time my application sees the connection went down and came back up. And it is the time that sometimes I see those error messages until I restart one of the application and have the socket connected again. What do you think? Re: Client Socket and connection problem Mark Salsbery20-Mar-07 10:04 Mark Salsbery 20-Mar-07 10:04  I think then that the connection is closed and needs to be reconnected. That would explain the NOTSOCK error since the socket became invalid at some point. That also explains the WSAECONNRESET error. When you get that error the connection is closed. That means you should close the socket and reconnect. "Great job, team. Head back to base for debriefing and cocktails." (Spottswoode "Team America")
