Removing Non-Client area of a window alexei_p18-Jun-04 1:36 alexei_p 18-Jun-04 1:36  How can I remove non-client area of a window (border & title), which belongs to another process (separate application)? I have only HWND of that window, and cutting its DC using SetLayeredWindowAttributes() with LWA_COLORKEY, to get some specific shape, but all non-client area remains as an ugly frame. So I need to remove it somehow. Note: the window is created by existing application, and I can’t change its code Re: Removing Non-Client area of a window Ravi Bhavnani18-Jun-04 2:43 Ravi Bhavnani 18-Jun-04 2:43  You might want to try hooking the window and handling WM_NCPAINT. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Handling of window opening alexei_p18-Jun-04 1:33 alexei_p 18-Jun-04 1:33  1) How to handle opening of a window, which belongs to another process (separate application)? The window has unique title, but not unique class. I need more intelligent way, than just calling FindWindow() from infinite loop 2) How can I monitor and handle closing/terminating of that window, after I found it?

I don't know properly how to program to detect window open, but I know that is the most efficently way to detect. Look in codeproject for hook.

Re: free pointer problem jmkhael18-Jun-04 1:15 jmkhael 18-Jun-04 1:15  double** configurations; configurations = (double**)malloc(sizeof(double*)); Here you are allocating a pointer to a pointer to double for(int i=0;i < max;i++) { configurations[i][0]=/*whatever*/ configurations[i][1]=/*whatever*/ } Here you are writing to a non allocated memory. I would go for: double **ppdDoubleMatrix = (double **) calloc(iRows, sizeof(double *)); if(ppdDoubleMatrix) { for (iRowsCounter = 0; iRowsCounter < iRows; iRowsCounter++) { ppdDoubleMatrix[iRowsCounter] = (double *) calloc(iColumns, sizeof(double)); } } Freeing it like so: for (iRowsCounter = 0; iRowsCounter < pxThis->iRows; iRowsCounter++) { if (ppdDoubleMatrix[iRowsCounter]) { free(ppdDoubleMatrix[iRowsCounter]); ppdDoubleMatrix[iRowsCounter] = NULL; } } // Free the pointer free(ppdDoubleMatrix); ppdDoubleMatrix = NULL; Papa while (TRUE) Papa.WillLove ( Bebe ) ; Re: free pointer problem Rodrigo Pinto Pereira de Souza18-Jun-04 1:54 Rodrigo Pinto Pereira de Souza 18-Jun-04 1:54  for(int i=0;i < max;i++) { free(configurations[i][0]); free(configurations[i][1]); } Enjoy it Rodrigo Pinho Pereira de Souza Using VC++6 .dll and .lib in VC.NET Freddie Code18-Jun-04 0:58 Freddie Code 18-Jun-04 0:58  I'm trying to use a .dll and .lib that was created in VC++6 with a new VC.NET project. I add the .dll and .lib to the linker options and #include the cooresponding .h file to the project. I can't get the program to recongnize the function in the .dll and .lib correctly. It seems that .NET does not like the way the functions in the .h file are declared, or something? Is there something new in VC.NET that I need to know with regards to using .lib and .dll? Help!

Best Regards, Irshad general question about network traffic detection SireNexus17-Jun-04 23:27 SireNexus 17-Jun-04 23:27  Hello, i want to develop a tool for winXP that dynamically limits Intenet (IP) bandwith on a LAN host (LAN connected to Internet via router). the tool should run on all LAN clients and send information about the current IP traffic on the client to the other clients. with this information it should limit the bandwith to a predefined value, if the other clients need full bandwith, too. for example: if three clients need full bandwith all get limited to 1/3 of the full bandwith available. if just one client need full bandwith it should get all. thats the theory. to manage this, i need to detect the current ip traffic on a client. searching the web brought me to MS IpHlpApi.lib but it only detects IP datagram amounts, not the real size if an ip-packet. next solution is ip-packet sniffing, but this need as far as i now, developing a kernel mode driver. i know about pcap library for packet sniffing task but it doesnt allow packet manipulation. i dont need packet manipulation for my task, but ive got another project in mind that does, so i want to go the straight (maybe hard) way. i thought about using MS Visual C++ with MFC and DDK so my question: what would you suggest for solving my problem? best regards Robert Re: general question about network traffic detection Trollslayer18-Jun-04 1:34 Trollslayer 18-Jun-04 1:34  This sounds like any firewall code would do that.

Thanks, that worked . Re: Check for existing directory James R. Twine18-Jun-04 11:47 James R. Twine 18-Jun-04 11:47     Why not just call CreateDirectory(...) and be done with it?  If the directory does not exist, it will be created and if it does exist, you will get back an ERROR_EXISTS error code.  Either way, you get want you want and will likely be faster than doing you own check(s) first.    But the Shell LWAPI function PathFileExists(...) was designed for checking for the existance of files/directories...    Peace! -=- James Tip for SUV winter driving survival: "Professional Driver on Closed Course" does not mean "your Dumb Ass on a Public Road"!

Shaw 17-Jun-04 22:06  What I am looking for is a state machine diagram showing how to decipher a regular expression. I've searched the www and have half a dozen pieces of source code that process regular expressions, plus I've read more articles on NFA's and DFA's than I care to think about. None of them give me what I am looking for. I am working on developing my own diagram, but it is far more complicated than it appears on the surface. I've written DFA's to handle kown cases (keywords,numbers,etc..), but what I want is to allow the user to enter in a regular express that my code can use to generate a (specific) DFA in memory.

As for auto-returning, you might want to handle the EN_UPDATE notification message for the edit.
