  • How can i use complextype class or multi type class is it generic collection?

    - by programmerist
    i need a complex returning type. i have 4 class returning types COMPLEXTYPE must include Company, Muayene, Radyoloji, Satis because i must return data switch case situation how can i do? Maybe i need generic collections How can i do that? public class GenoTipController { public COMPLEXTYPE Generate(DataModelType modeltype) { _Company company = null; _Muayene muayene = null; _Radyoloji radyoloji = null; _Satis satis = null; switch (modeltype) { case DataModelType.Radyoloji: radyoloji = new Radyoloji(); return radyoloji; break; case DataModelType.Satis: satis = new Satis(); return satis; break; case DataModelType.Muayene: muayene = new Muayene(); return muayene; break; case DataModelType.Company: company = new Company(); return company; break; default: break; } } } public class CompanyView { public static List GetPersonel() { GenoTipController controller = new GenoTipController(); _Company company = controller.Generate(DataModelType.Company); return company.GetPersonel(); } } public enum DataModelType { Radyoloji, Satis, Muayene, Company }

  • UML Diagrams. When are they used?

    - by user69514
    So ok I understand that UML diagrams help for the construction of a program, but when are they used? Are they needed before you start coding? do you need them so you know what you have to code? Or do you use them after you have coded the program?

  • Get logged in user details in sharepoint c# webpart

    - by MalphasWats
    Hi, After much wrangling I have a development environment for building sharepoint webparts in c#. I'm completely new to SP development, so I haven't quite found the various API docs, so I'm hoping someone can help get me started. Eventually, I want to write a simple web part that allows its user to display different content depending on who the current user is. What I'd like to do first though is just build a dead simple webpart that will simply print out the current user's details - username, full name and any permissions groups that they have. Thanks

  • Is it worth using std::tr1 in production?

    - by flashnik
    I'm using MS VC 2008 and for some projects Intel C++ compiler 11.0. Is it worth using tr1 features in production? Will they stay in new standard? For example, now I use stdext::hash_map. TR1 defines std::tr1::unordered_map. But in MS implementation unordered_map is just theirs stdext::hash_map, templatized in another way.

  • Clear data at serial port in Linux in C?

    - by ipkiss
    Hello guys, I am testing the sending and receiving programs with the code as The main() function is below: include include include include include include include "read_write.h" int fd; int initport(int fd) { struct termios options; // Get the current options for the port... tcgetattr(fd, &options); // Set the baud rates to 19200... cfsetispeed(&options, B9600); cfsetospeed(&options, B9600); // Enable the receiver and set local mode... options.c_cflag |= (CLOCAL | CREAD); options.c_cflag &= ~PARENB; options.c_cflag &= ~CSTOPB; options.c_cflag &= ~CSIZE; options.c_cflag |= CS8; // Set the new options for the port... tcsetattr(fd, TCSANOW, &options); return 1; } int main(int argc, char **argv) { fd = open("/dev/pts/2", O_RDWR | O_NOCTTY | O_NDELAY); if (fd == -1) { perror("open_port: Unable to open /dev/pts/1 - "); return 1; } else { fcntl(fd, F_SETFL, 0); } printf("baud=%d\n", getbaud(fd)); initport(fd); printf("baud=%d\n", getbaud(fd)); char sCmd[254]; sCmd[0] = 0x41; sCmd[1] = 0x42; sCmd[2] = 0x43; sCmd[3] = 0x00; if (!writeport(fd, sCmd)) { printf("write failed\n"); close(fd); return 1; } printf("written:%s\n", sCmd); usleep(500000); char sResult[254]; fcntl(fd, F_SETFL, FNDELAY); if (!readport(fd,sResult)) { printf("read failed\n"); close(fd); return 1; } printf("readport=%s\n", sResult); close(fd); return 0; } read_write.h: #include <stdio.h> /* Standard input/output definitions */ include /* String function definitions */ include /* UNIX standard function definitions */ include /* File control definitions */ include /* Error number definitions */ include /* POSIX terminal control definitions */ int writeport(int fd, char *chars) { int len = strlen(chars); chars[len] = 0x0d; // stick a after the command chars[len+1] = 0x00; // terminate the string properly int n = write(fd, chars, strlen(chars)); if (n < 0) { fputs("write failed!\n", stderr); return 0; } return 1; } int readport(int fd, char *result) { int iIn = read(fd, result, 254); result[iIn-1] = 0x00; if (iIn < 0) { if (errno == EAGAIN) { printf("SERIAL EAGAIN ERROR\n"); return 0; } else { printf("SERIAL read error %d %s\n", errno, strerror(errno)); return 0; } } return 1; } and got the issue: In order to test with serial port, I used the socat (https://help.ubuntu.com/community/VirtualSerialPort ) to create a pair serial ports on Linux and test my program with these port. The first time the program sends the data and the program receives data is ok. However, if I read again or even re-write the new data into the serial port, the return data is always null until I stop the virtual serial port and start it again, then the write and read data is ok, but still, only one time. (In the real case, the sending part will be done by another device, I am just taking care of the reading data from the serial port. I wrote both parts just to test my reading code.) Does anyone have any ideas? Thanks a lot.

  • Displaying console output?

    - by ClarkeyBoy
    I am currently creating a customer application for a local company. I have a datagridview linked to the customers table, and I am trying to link it up so that updates, inserts and deletions are handled correctly. I am very new to c# so I am starting with the basics (like about 2 days ago I knew nothing - I know vb.net, Java and several other languages though..). Anywho from what I understand anything output through Debug.WriteLine should only appear when in debug mode (common sense really) but anything output through Concole.WriteLine should appear whether or not in debug mode. However I have checked the immediate and output windows and nothing is being output when in normal mode. Does anyone have any idea why this is?? Edit: I have event handlers for clicking a cell - it should output CellClicked and set the gridview to invisible when a cell is clicked. The latter works whichever mode I am in, but CellClicked is only output in debug mode. I am using Console.WriteLine("CellClicked").

  • Display exception information and Debug.Print() messages in Immediate Window

    - by Timwi
    A friend of mine claims that calls to Debug.Print() as well as first-chance exception notifications appear in the Immediate Window for him. I found this surprising; for me they only appear in the Output Window. MSDN claims (here) that you can implicitly enable them in the Immediate Window by explicitly disabling them in the Output Window. But that doesn't work for me; the messages are not shown in either window if I disable this. The Immediate Window remains empty. How do I get the Immediate Window to display this information?

  • Source control products that support linked/shared files?

    - by Ian Boyd
    We're interested in moving from a source control system that supports the concept of shared or linked files. A shared file means: a file modified in one project, is automatically updated changed in every other project that uses that same file. It does this without a developer having to request it, reverse-integrate it, ask for it, or even want it. We're trying to see if any other commonly used source-control systems can meet our needs, and include linked or shared files. My limited research shows that: Team Foundation Server doesn't support sharing files Subversion doesn't support sharing files (including Externals) CVS doesn't support sharing files (including Modules) Anything else? (besides our current source control product, obviously) References Subversion and shared files across repositories/projects? How to share files between CVS projects? Will TFS ever support shared files for projects under source control?

  • Using pthread to perform matrix multiplication

    - by shadyabhi
    I have both matrices containing only ones and each array has 500 rows and columns. So, the resulting matrix should be a matrix of all elements having value 500. But, I am getting res_mat[0][0]=5000. Even other elements are also 5000. Why? #include<stdio.h> #include<pthread.h> #include<unistd.h> #include<stdlib.h> #define ROWS 500 #define COLUMNS 500 #define N_THREADS 10 int mat1[ROWS][COLUMNS],mat2[ROWS][COLUMNS],res_mat[ROWS][COLUMNS]; void *mult_thread(void *t) { /*This function calculates 50 ROWS of the matrix*/ int starting_row; starting_row = *((int *)t); starting_row = 50 * starting_row; int i,j,k; for (i = starting_row;i<starting_row+50;i++) for (j=0;j<COLUMNS;j++) for (k=0;k<ROWS;k++) res_mat[i][j] += (mat1[i][k] * mat2[k][j]); return; } void fill_matrix(int mat[ROWS][COLUMNS]) { int i,j; for(i=0;i<ROWS;i++) for(j=0;j<COLUMNS;j++) mat[i][j] = 1; } int main() { int n_threads = 10; //10 threads created bcos we have 500 rows and one thread calculates 50 rows int j=0; pthread_t p[n_threads]; fill_matrix(mat1); fill_matrix(mat2); for (j=0;j<10;j++) pthread_create(&p[j],NULL,mult_thread,&j); for (j=0;j<10;j++) pthread_join(p[j],NULL); printf("%d\n",res_mat[0][0]); return 0; }

  • ComboBox's Selected Value Changed On Lost Focus in VB.NET

    - by tunwn
    I have a datagridview(dgv) with a DataGridViewComboBoxColumn(colLocation) colLocation.AutoComplete = False colLocation.HeaderText = "Stored to" colLocation.DataSource = DB.getLocation() colLocation.DisplayMember = "description" colLocation.ValueMember = "id" I added the colLocation to dgv. "descirption" contains Unicode characters. I can see the comboBox correctly and choose the item. The problem is when the comboBox lost the focus, the value is changed to first item of the comboBox. Any suggestion? Updated: I found out that the ComboBox doesn't change the data when the DisplayMember is in English characters. It changes only when the DisplayMember is in Unicode chracter. Any idea for how could solve this? – tunwn 0 secs ago

  • Confused over behavior of List.mapi in F#

    - by James Black
    I am building some equations in F#, and when working on my polynomial class I found some odd behavior using List.mapi Basically, each polynomial has an array, so 3*x^2 + 5*x + 6 would be [|6, 5, 3|] in the array, so, when adding polynomials, if one array is longer than the other, then I just need to append the extra elements to the result, and that is where I ran into a problem. Later I want to generalize it to not always use a float, but that will be after I get more working. So, the problem is that I expected List.mapi to return a List not individual elements, but, in order to put the lists together I had to put [] around my use of mapi, and I am curious why that is the case. This is more complicated than I expected, I thought I should be able to just tell it to make a new List starting at a certain index, but I can't find any function for that. type Polynomial() = let mutable coefficients:float [] = Array.empty member self.Coefficients with get() = coefficients static member (+) (v1:Polynomial, v2:Polynomial) = let ret = List.map2(fun c p -> c + p) (List.ofArray v1.Coefficients) (List.ofArray v2.Coefficients) let a = List.mapi(fun i x -> x) match v1.Coefficients.Length - v2.Coefficients.Length with | x when x < 0 -> ret :: [((List.ofArray v1.Coefficients) |> a)] | x when x > 0 -> ret :: [((List.ofArray v2.Coefficients) |> a)] | _ -> [ret]

  • What makes Ometa special?

    - by Brian
    Ometa is "a new object-oriented language for pattern matching." I've encountered pattern matching in languages like Oz tools to parse grammars like Lexx/Yacc or Pyparsing before. Despite looking at example code, reading discussions, and talking to a friend, I still am not able to get a real understanding of what makes Ometa special (or at least, why some people think it is). Any explanation?

  • Tricking a Unix Commandline Program into Accepting a File Stream

    - by Alan Storm
    Hypothetical situation. I have a command line program in *nix (linux, BSD, etc.). It was written so that you pass it a text file as an argument $ program file.txt Run the program, it looks at the text in file.txt. Is it possible to "trick" this program into accepting input from a file stream rather than reading a file via disk? I'm pretty comfortable using unix pipes to do stuff, but there's still something a little mysterious about their internals that make it so I can't say (definitively) yes or not to the above question.

  • Switching from Sourcesafe - What to look for in a product

    - by asp316
    We're looking to move off of sourcesafe and on to a more robust source control system for our .Net apps. We're also looking for scripted/automated deployments. I'm a .Net developer (web and winforms). However, most of our development staff is RPG for the IBM iSeries and the devs use Aldon's LMI for source control and deployment. Our manager would prefer to stick with Aldon so all of our products are in the same system. However, I don't have experience with Aldon's products on the .Net side. I've used TFS and Subversion with Tortoise a bit, but not enough to recommend one or the other, especially in comparison to Aldon's product. Does anybody have experience with Aldon's products? If so, thoughts please? Also, other than the obvious things source control systems do, are there things I should avoid or are there must haves? I'm open to any system. A bit of background, I'm the only .Net dev in our company but I let operations do the deployments. I do want the ability to support concurrent checkouts if we hire a new dev.

  • The Benefits of Constants

    - by onaclov2000
    I understand one of the big deals about constants is that you don't have to go through and update code where that constant is used all over the place. Thats great, but let's say you don't explicitly declare it as a constant. What benefit(s) exist(s) to take a variable that HAPPENS to actually not be changed and make it a constant, will this save on processing, and/or size of code...etc? Basically I have a program that the compiler is saying that a particular variable is not changed and thus can be declared a constant, I just wanted to know what the benefit to adding the constant qualifier to it would be, if it makes no difference then making that change adds no value and thus no point wasting time (this same scenario occurs in more then one place) going back and "fixing" all these variables. Thank you, onaclov

  • How can I set MAXLENGTH on input fields automatically?

    - by Gary McGill
    I'm using ASP.NET MVC RC2. I have a set of classes that were auto-generated "Linq-to-SQL Classes", where each class models a table in my database. I have some default "edit" views that use the neat-o Html.TextBoxFor helper extension to render HTML input fields for the columns in a table. However, I notice that there is no MAXLENGTH attribute specified in the generated HTML. A quick google shows that you can add explicit attributes using TextBoxFor etc. but that would mean that I need to hard-code the values (and I need to remember to do it for every input). This seems pretty poor, considering that everything was automatically generated directly from the DB, so the size of the columns is known. (Although, to be fair, the web-side stuff has to work with any model objects, not just with Linq-to-SQL objects). Is there any nice way of getting this to do the right thing?

  • Access 2007 VBA : Building a listbox with selection choices from another list box

    - by Justin
    So there are 8 categories that may be associated to each order, but not necessarily all of them. So i was going to build a list box that allowed the user to double click each of the category they wish to associate when they have an "Order Detail" form opened up (unbound form that has hidden text boxes with all needed ID numbers). I want to have another empty text box right beside it that will allow me to append the selections (up to 8) so the user can see that they have been added. So one list box with the default choices, and when a choice is double clicked, it adds that choice to the second list box to see the tally so to speak. What is the VB for getting something like this done? Thanks Justin
