Rayman How to close a file opened with CreateFile API SAK4-Oct-01 9:27 SAK 4-Oct-01 9:27  I have opened and successfully read from a text file using CreateFile and ReadFile api's, but how can I close the file. Thank you Re: How to close a file opened with CreateFile API Chris Losinger4-Oct-01 9:51 Chris Losinger 4-Oct-01 9:51  CloseHandle -c ------------------------------ Smaller Animals Software, Inc. http://www.smalleranimals.com Re: How to close a file opened with CreateFile API SAK4-Oct-01 12:12 SAK 4-Oct-01 12:12  Thank you for the information, much appreciated! Re: How to close a file opened with CreateFile API Lim Bio Liong3-Dec-01 0:41 Lim Bio Liong 3-Dec-01 0:41  I assume you are developing in Win32. Use CloseHandle() to close the file. The following is taken from the Win32 documentation for CreateFile() : "Use the CloseHandle function to close an object handle returned by CreateFile." Note that it is very important to call CloseHandle(). Otherwise, the handle table of your application will continue to grow and you will run out of memory in the long term. After closing the handle, it is best to set the value of your handle variable to NULL so that you do not close the handle again. Closing a handle twice will raise an exception. SQL CE Skip Pattern Surveying Terence4-Oct-01 5:00 Terence 4-Oct-01 5:00  I am interested in using Windows SQL CE for skip pattern surveying and metric analysis of said data. I will need to drill down 4-8 query references in a PDA environment with speed being a very important issue (less than 1 sec lag between acceptance of option and drill down to next layer).

I've created a MFC application that is linked to OpenGL. How do I created functions like the ones we see in the "Paint" program found in windows accesories? For example, if I click on the menu which as a "draw lines" function and after clicking on that, I would like to use the mouse to draw lines, (line starts when the mouse is clicked and dragged. Then the line stops when mouse is released). I'm having great difficulty doing this and if anyone can help it would be greatly appreciated. Thank you in advance!

Override OnLeftMouseDwn Store the position of the mouse when clicked, set a flag to tell that the left button is down, 2. Override OnMove Store the position of the actual position of the mouse, ask for redraw, (InvalidateRect(NULL,FALSE); 3. In OnDraw, check if left button is down, if so, draw a line from initial position to actual position, 4. Override OnLeftMouseUp, unset the flag. This is the basic idea, of course you can refine the concept. Jonathan de Halleux, Belgium. NET DataSet Implemented in Visual C++ jawillia993-Oct-01 4:36 jawillia99 3-Oct-01 4:36  I am looking for a "unmanaged" implementation of the .NET DataSet and its associated objects that is written in Visual C++ (with source if possible). I need an implementation that does not rely on the .NET FrameWork, yet is compatible with the .NET DataSet's so I can share the XML form of the DataSet between unmanaged clients (.NET is not installed on the clients) and a .NET web service. We will be using the DataSet's as our universal datapacket to pass data between the client and server. I am trying to put off having to implement a solution myself in ATL so I am doing some research first. Thanks in advanced for any information or assistance. Send Replies to jwilliams@paymetric.com Removing cursor from Richedit control Newbie3-Oct-01 0:34 Newbie 3-Oct-01 0:34  I would like to have a Window in one of my dialogs that just displays text. I do not want the user to modify it. However, I would like to have the freedom of formatting the text (e.g. bold, italic etc...) and using different fonts. I thought the easiest way of doing this was to use a RichEdit control set to ReadOnly. This works OK, but it still has a cursor flashing in the rich edit box when the user gives it focus. I have seen that other applications can display text /graphics in this way, but without the cursor flashing (e.g. MSDN Library). Does anyone know how this can be done?

What I want to have is the macro which builds project, but then checks if any files were changed since that build and if so - builds again, otherwise stops. I hope this replacement for standard build command will help many people. Thanks.

PATWAL Ip phone ah_san30-Sep-01 20:51 ah_san 30-Sep-01 20:51  Anyone know code for the food ordering through the ip phone. Thank confused: Palm programming for SMS ( Code request ) yskinny30-Sep-01 20:31 yskinny 30-Sep-01 20:31  Hi there everyone I recently have a project on developing an Interactive Location Determintion System using GSM/SMS.It involves the study on using PDA (Handspring Palm) to control the Wavecom GSM module and the possibiltiy of multiplexing its control between a GPS module and the WaveCom GSM module. Well,i really have no idea on how to start.The main purpose now is write a program for Handspring Palm to send SMS to a module which in transmit the message to a mobile phone will do.I have to use the codewarrior software with c language and AT commands.If this is successful, the next step would be for the mobile phone to auto send back the location of the user.Its like a small tracking device.For the second part,my supervisor told me to think about how to modify the serial ports on the palm to be able to mutliplex between the 2modules i mention earlier.Can anyone out there please give my some hints on how to start this project.I would be better if someone who had done something similiar please share your program with me.Right now,i need the codes for sending SMS.The SMS program need not be a complicated one.I"am now more on a rush on the SMS part. Please reply ASAP if any one can help.Thanks a lot.

Ryan Park25-Sep-01 19:31 Ryan Park 25-Sep-01 19:31  Hi, I need to implement graphical diagram for our product. Its use is for graphical representation of data binding between controls and between tiers (right term? I mean which client to which server.). I have littl idea about this yet, and would be very grateful if there are any good free code for starting point. And..the worst act for my scenario is.. 1.Say, when user loads data from disk, I know connection data between diagrams (controls) but have no information about graphical representation. Then how can I draw visual connection between diagrams without intersection? And how can I decide the best-viewing to user? Any Ideas? 2.Without #1's answer,should I archive all graphical connections between diagrams? If so, how can I archive connection line's data to disk? I guess there should be "node" concept, but it's hard to "HOW". So I'm searching the best fitting free code for fast and reliable development. Any suggestion? Thanks a million. Regards, Ryan
