How Do We Create a Checker Game? jeff1922-Mar-06 9:14 jeff19 22-Mar-06 9:14  Can anyone direct me as to where to find examples of how to create a strategy game, such as checkers, by using C# in a windows application? I am most interested in how to draw a checker board and checker pieces, and how to allow the user to drag and drop a checker piece. I have been unsuccessful in finding this, so far, and it would be really neat to play with this type of code. Thanks. jeff19 Re: How Do We Create a Checker Game? DigitalKing22-Mar-06 18:40 DigitalKing 22-Mar-06 18:40  Here[^] is an excellent example of chess. Look at the source to learn about drawing a board with GDI+ and handling mouse events. Re: How Do We Create a Checker Game? Member 156244864-May-22 5:17 Member 15624486 4-May-22 5:17  Does anyone have an updated link for this? I am also trying to create a checkers game using C# with a .Net Framework and this link for the chess setup doesnt seem to work for me. Any help would be greatly appreciated. Hiding a Tab Control Franz Klein22-Mar-06 9:11 Franz Klein 22-Mar-06 9:11  I have tried using the following code: TapPage.Hide() to make a tab page invisible but nothing happens it just sits there laughing at me. The tab page is placed on a Window Form in the Form design area and is not created dynamically. Does anybody know what I can do to make it invisible? I am the handsome one in the crowd. Re: Hiding a Tab Control jonas_berg22-Mar-06 10:05 jonas_berg 22-Mar-06 10:05  This is another way, "removing" it: tabControl.TabPages.RemoveByKey("TapPage"); /j Re: Hiding a Tab Control Ed.Poore22-Mar-06 10:06 Ed.Poore 22-Mar-06 10:06  I think you have to remove the tab, that's the only way I can remember. Ed Progressive vs. Baseline JPEG SylvesterW22-Mar-06 9:10 SylvesterW 22-Mar-06 9:10  Hi, I need to distinguish progressive jpeg's from baseline jpeg's. So far I retrieved all image properties using image.GetPropertyItem, and all properties are the same for these two kinds. There is also function GetEncoderParameterList, but it can only (at least as far as I know) be used to set encoding properties when you want to save a file. Do you know maybe how can I use GetEncoderParameterList for my purpose? Or, how can I distinguish these two types of JPEG's by reading and comparing bytes from image file. Thanks SW Re: Progressive vs. Baseline JPEG DaBears22-Mar-06 11:39 DaBears 22-Mar-06 11:39  Progressive information is held in the JPEG compression header. You need to read in the jpeg file then access the fields by address. There are three single byte address fields (0xC2, 0xC6, 0xCA) that holds progressive information. Generally I think 0xC2 is always set if the jpeg is progressive. So create a struct that contains the information you want and then read the file into that struct (fread, or the .NET equivlant), and then access the proper field. Mike Re: Progressive vs. Baseline JPEG SylvesterW22-Mar-06 19:45 SylvesterW 22-Mar-06 19:45  Mike, Thank you for fast response. Could you post a sample code how I could access and retrieve that info using byte address fields (or a link to a website with similar code). I'm a kind of new to image processing and example would help me a lot. Thank you again, Sylvester Re: Progressive vs. Baseline JPEG DaBears23-Mar-06 5:36 DaBears 23-Mar-06 5:36  Hey Sly, Here is a link to some code samples to give you an idea on what to do. Don't follow exactly because the addressing doesn't line up, the BITMAPINFO struct doesn't break out the progressive address so you would have mask the information you need out of what it does hold. http://www.experts-exchange.com/Programming/Q_21769844.html[^] The last post might be a little better info. Also these snippets are written in C so you would have to translate that to C# .NET. Since I haven't done this type of stuff in .NET I can't tell where to head. -Mike Re: Progressive vs. Baseline JPEG SylvesterW23-Mar-06 11:17 SylvesterW 23-Mar-06 11:17  Mike, Unfortunately I don't have subscription on experts-exchange, but at least I know what to look for. Thanks Sly Re: Progressive vs. Baseline JPEG DaBears23-Mar-06 11:30 DaBears 23-Mar-06 11:30  Sly, You don't need a subscription (I don't) just scroll down far enough and you will see the whole post, you have to get past all the ads, and don't click on the "View Solution" button. But just in case I am getting lucky: Based on the info here: http://www.fastgraph.com/help/jpeg_header_format.html You can read in the necessary info, similarly to how I demonstrated with the above code (for bitmap). Firstly, define a struct to store the JPEG header info in: struct JPEGINFOHEADER { unsigned short id ; unsigned short width ; unsigned short height ; unsigned char number_of_component ; // etc etc } ; /** * Return value: * 0 - Successful * -1 - Could not find/open the specified file * -2 - Specified file is not a valid bitmap file */ int LoadJpegHeader( char *filename, JPEGINFOHEADER *jpegInfoHeader ) { FILE *filePtr ; filePtr = fopen( filename, "rb" ) ; if ( filePtr == NULL ) { return -1 ; } fread( JpegInfoHeader, sizeof(JPEGINFOHEADER), 1, filePtr ) ; fclose( filePtr ) ; return 0 ; } Re: Progressive vs. Baseline JPEG SylvesterW23-Mar-06 19:13 SylvesterW 23-Mar-06 19:13  Mike, You are right, when I saw "View solution" I didn't even scroll down the page. I also found a book which covers that topic very well. The title is: "Compressed Image File Formats: jpeg, png, gif, xbm, bmp" by John Miano, 1999 It also has a CD with console application (jpegdump) written in c++ extracting all info from jpeg file. Now, I only need to convert it to c#. Great!!! Thanks Sylvester C# Generating Outlook contacts Paul Sullivan22-Mar-06 8:57 Paul Sullivan 22-Mar-06 8:57  I have a web app and I would like to create Outlook contacts and assign them to groups in the Outlook address book.

Thanks paul binding a datagrid to an arraylist brianmelion22-Mar-06 8:21 brianmelion 22-Mar-06 8:21  Hi, in a windows form I am trying to populate a datagrid from an arraylist. instead of getting the text value I am getting the length of each string in the array passed to the grid, in this case the number "5" ArrayList list = new ArrayList(); list.Add("Test1"); list.Add("Test2"); dataGrid1.DataSource = list; Any ideas? thanks brian How to get User Idle time engsrini22-Mar-06 7:17 engsrini 22-Mar-06 7:17  Hi all, I developing a windows application which will have login verification and other stuffs. I want to lock the application when the user is idle (as like in windows ctrl+alt+del lock) for some time(say 1 hour - it should be confiurable parameter). how can i do that in c# I found one event in Application.idle but this event trigger once the UI get painted. Regards, Srini Re: How to get User Idle time Wjousts22-Mar-06 10:03 Wjousts 22-Mar-06 10:03  I use a class that implements IMessageFilter that is added as a message filter after the user has logged in (i.e. Application.AddMessageFilter). The filter contains a timer that gets reset everytime a mouse or keyboard message is received. If the timer ticks (i.e. no mouse or keyboard activity for a defined period of time - five minutes in my case) then my application becomes "inactive" (actually all it does is stop counting how much time the user has been using the program). When a new keyboard or mouse event is received while the app is sleeping it will wake back up and start tracking time again.

We are going to spend around $8000 and just wanted to know if anyone has had any negative experience with them. I cant seem to find any reviews online so I am asking the CP community for help. Adding custom control with CollectionEditor doesn't refresh form DaBears22-Mar-06 4:12 DaBears 22-Mar-06 4:12  I created a custom control inherited from panel that will contain a collection of another custom control. I added an attribute 'Items' that startes the Collection Editor and adds however many instances of the the controls and add it to a collection class. All works fine, the control gets added to the collection, InitializeComponent gets modified, but for the new control to show up on the form I need to rebuild the parent form, THEN it shows up. So my question is, does anyone have tips on what I need to do to get the control added to the collection to actually be displayed on the form upon adding it to the collection? -Mike (ps removal using the Collection Editor works fine) Sudoku puzzle program eric_tran22-Mar-06 4:10 eric_tran 22-Mar-06 4:10  Hi everyone, I've been developing the Sudoku puzzle program.
