  • What is it going here in my solution?

    - by bbb
    I am a asp.net mvc programmer and if I want to start a project I do this: I make a class library named Model for my models. I make a class library named Infrastructure.Repository for database processes I make a class library named Application for business logic layer And finally I make a MVC project for the UI. But now some things are confusing me. Am I using 3-tier programming? If yes so what is n-tier programming and which one is better? If no so what is 3-tier programming? Some where I see that the tiers namings are DAL and BIZ. Which one is correct according to the naming convention?

  • What is the steps to make a frame work for a company? [on hold]

    - by bbb
    we want to make a frame work for our company. Our company mission is developing web applications and CMS and websites. Till now we had a lot of problems with the various types of codding. we didnt have a frame work and every programmer codes as he wants and it was too hard for the others to edit them. Now we want to make a frame work for the company. We want to make an archive of dll files that are written by our self our other and make the programmers to use just from them and we want to make a frame work for the type of codding. WE NEED A STRUCTURE FOR THE COMPANY. I dont know how to do this and what is the first and second and third step to do this. I need some guidance about it. For example I say that the frame work should contains the followings: The base should be SOLID The method should be Code-First The standards should be Naming Convention The type should be 3 layer programming The method should be MVC We should use from our dll archive The UI should be with HTML and CSS And using from Bootstrap Am I right or not or is it complete or...???

  • Passing Strings by Ref

    - by SGWellens
    Humbled yet again…DOH! No matter how much experience you acquire, no matter how smart you may be, no matter how hard you study, it is impossible to keep fully up to date on all the nuances of the technology we are exposed to. There will always be gaps in our knowledge: Little 'dead zones' of uncertainty. For me, this time, it was about passing string parameters to functions. I thought I knew this stuff cold. First, a little review... Value Types and Ref Integers and structs are value types (as opposed to reference types). When declared locally, their memory storage is on the stack; not on the heap. When passed to a function, the function gets a copy of the data and works on the copy. If a function needs to change a value type, you need to use the ref keyword.  Here's an example:     // ---- declaration -----------------     public struct MyStruct    {        public string StrTag;    }     // ---- functions -----------------------     void SetMyStruct(MyStruct myStruct)     // pass by value    {        myStruct.StrTag = "BBB";    }     void SetMyStruct(ref MyStruct myStruct)  // pass by ref    {        myStruct.StrTag = "CCC";    }     // ---- Usage -----------------------     protected void Button1_Click(object sender, EventArgs e)    {        MyStruct Data;        Data.StrTag = "AAA";         SetMyStruct(Data);        // Data.StrTag is still "AAA"         SetMyStruct(ref Data);        // Data.StrTag is now "CCC"    } No surprises here. All value types like ints, floats, datetimes, enums, structs, etc. work the same way. And now on to... Class Types and Ref     // ---- Declaration -----------------------------     public class MyClass    {        public string StrTag;    }     // ---- Functions ----------------------------     void SetMyClass(MyClass myClass)  // pass by 'value'    {        myClass.StrTag = "BBB";    }     void SetMyClass(ref MyClass myClass)   // pass by ref    {        myClass.StrTag = "CCC";    }     // ---- Usage ---------------------------------------     protected void Button2_Click(object sender, EventArgs e)    {        MyClass Data = new MyClass();        Data.StrTag = "AAA";         SetMyClass(Data);          // Data.StrTag is now "BBB"         SetMyClass(ref Data);        // Data.StrTag is now "CCC"    }  No surprises here either. Since Classes are reference types, you do not need the ref keyword to modify an object. What may seem a little strange is that with or without the ref keyword, the results are the same: The compiler knows what to do. So, why would you need to use the ref keyword when passing an object to a function? Because then you can change the reference itself…ie you can make it refer to a completely different object. Inside the function you can do: myClass = new MyClass() and the old object will be garbage collected and the new object will be returned to the caller. That ends the review. Now let's look at passing strings as parameters. The String Type and Ref Strings are reference types. So when you pass a String to a function, you do not need the ref keyword to change the string. Right? Wrong. Wrong, wrong, wrong. When I saw this, I was so surprised that I fell out of my chair. Getting up, I bumped my head on my desk (which really hurt). My bumping the desk caused a large speaker to fall off of a bookshelf and land squarely on my big toe. I was screaming in pain and hopping on one foot when I lost my balance and fell. I struck my head on the side of the desk (once again) and knocked myself out cold. When I woke up, I was in the hospital where due to a database error (thanks Oracle) the doctors had put casts on both my hands. I'm typing this ever so slowly with just my ton..tong ..tongu…tongue. But I digress. Okay, the only true part of that story is that I was a bit surprised. Here is what happens passing a String to a function.     // ---- Functions ----------------------------     void SetMyString(String myString)   // pass by 'value'    {        myString = "BBB";    }     void SetMyString(ref String myString)  // pass by ref    {        myString = "CCC";    }     // ---- Usage ---------------------------------     protected void Button3_Click(object sender, EventArgs e)    {        String MyString = "AAA";         SetMyString(MyString);        // MyString is still "AAA"  What!!!!         SetMyString(ref MyString);        // MyString is now "CCC"    } What the heck. We should not have to use the ref keyword when passing a String because Strings are reference types. Why didn't the string change? What is going on?   I spent hours unssuccessfully researching this anomaly until finally, I had a Eureka moment: This code: String MyString = "AAA"; Is semantically equivalent to this code (note this code doesn't actually compile): String MyString = new String(); MyString = "AAA"; Key Point: In the function, the copy of the reference is pointed to a new object and THAT object is modified. The original reference and what it points to is unchanged. You can simulate this behavior by modifying the class example code to look like this:      void SetMyClass(MyClass myClass)  // call by 'value'    {        //myClass.StrTag = "BBB";        myClass = new MyClass();        myClass.StrTag = "BBB";    } Now when you call the SetMyClass function without using ref, the parameter is unchanged...just like the string example.  I hope someone finds this useful.

  • Possible to set two values for two different nodes from user input in XForms?

    - by iHeartGreek
    Hi! I would like to set two values for two different nodes from user input in XForms. I am curious about how this is done, if at all possible. For example, if I have the following data model: <xf:instance id="criteria_data" xmlns=""> <criteria> <set> <root></root> <criterion></criterion> </set> </criteria> </xf:instance> <xf:instance id="choices" xmlns=""> <choices> <root label="The Choices">/AAA</root> <choice label="BBB">/@BBB</choice> </choices> </xf:instance> <xf:instance id="choices" xmlns=""> <choices> <root>/AAA</root> <choice label="BBB">/@BBB</choice> <choice label="CCC">/@CCC</choice> <choices> </xf:instance> <xf:bind id="data_criterion" nodeset="instance('criteria_data')/criteria/set/criterion"/> <xf:bind id="data_root" nodeset="instance('criteria_data')/criteria/set/root"/> <xf:bind id="choices_root" nodeset="instance('choices')/root"/> <xf:bind id="choices" nodeset="instance('choices')/choice"/> and my ui code looks like: <xf:select bind="data_criterion" appearance="full"> <xf:label>Your choices:</xf:label> <xf:itemset bind="choices"> <xf:label ref="@label"></xf:label> <xf:value ref="."></xf:value> </xf:itemset> </xf:select> But I essentially want it to be like this (though this is invalid and does not produce any xml at all): <xf:select appearance="full"> <xf:label>Your choices:</xf:label> <xf:itemset bind="choices"> <xf:label ref="@label"></xf:label> <xf:value bind="data_criterion" ref="."></xf:value> <xf:value bind="data_root" ref="instance('choices')/root"></xf:value> </xf:itemset> </xf:select> The XML output I want to achieve (if user checks "BBB"): <criteria> <set> <root>/AAA</root> <criterion>/@BBB</criterion> </set> </criteria> How can I achieve setting these two nodes for the one checkbox seletion? Hope that all made sense... Thanks! :)

  • ASP.NET web form Routing issue via UNC Path

    - by Slash
    I create a IIS 7.0 website via UNC path to load .aspx to dynamic compile files and runs. however, it's running perfect. I always use IIS URL Rewrite module 2 to rewrite my site URL n' its perfect, too. Today, I wanna use System.Web.Routing to implement url rewrite but I encountered difficulties... When I wrote code in Global.asax: System.Web.Routing.RouteTable.Routes.MapPageRoute("TEST", "AAA/{prop}", "~/BBB/CCC.aspx"); And it just CANNOT reDirect to /BBB/CCC.aspx When I type the URL(like: xx.xx.xx.xx/BBB/CCC.aspx) in browser directly, it runs normally that I want. (so it proof CCC.aspx is in right path.) thus, I copy all of the code and open VS2010 running with IIS 7.5 Express locally, it works perfect! e.g: in browser URL I type xx.xx.xx.xx/AAA/1234, it will turn to page xx.xx.xx.xx/BBB/CCC.aspx (Works perfect!) Why??? help me plz. thanks. Update: I think I should consider not UNC path to make it error! when I move all code to physical disk and setup IIS 7.0 to monitor this Folder, it still not works! But the same code run in VS2010 + IIS 7.5 Express it works!? so strange!

  • UriBuilder incorrectly encoding Query Parameters value ?

    - by Fred
    Lets consider the following code sample where a path and single parameter are encoded... Parameter name: "param" Parameter value: "foo/bar?aaa=bbb&ccc=ddd" (happens to be a url with query parameters) String test = UriBuilder.fromPath("https://dummy.com"). queryParam("param", "foo/bar?aaa=bbb&ccc=ddd"). build().toURL().toString(); The encoded URL string returned is: "https://dummy.com?param=foo/bar?aaa%3Dbbb&ccc%3Dddd" Is this correct ? Should not the character "&" (and may be even "?") be encoded in the parameter value string ? Would not the URL produced be interpreted as follow: One first parameter, name="param", value = "ar?aaa%3Dbbb" followed by a second parameter, name="ccc%3Dddd", without value.

  • nmake.exe: is there a way to exclude a file from a set of files specified in a macro?

    - by Cheeso
    I'm looking for something like the Exclude filter for msbuild, but I Want it in a makefile processed by nmake. Is that possible? Suppose I have a makefile that defines this macro: SOURCES=xxx.c yyy.c zzz.c and I invoke it with nmake OLD=xxx.c NEW=bbb.c ...can I produce, within the makefile, a macro with a value like: yyy.c zzz.c bbb.c ...basically substituting bbb.c for xxx.c ? The files can appear in any order. This would be pretty easy if the string substitution that is possible in nmake macros, allowed for evaluation of macros. In other words, I can do sources=xxx.c yyy.c zzz.c objs=$(sources:.c=.o) and the value of $(objs) is xxx.o yyy.o zzz.o But nmake does not allow a macro for the value of either argument to that substitution. I cannot do this: new=.o sources=xxx.c yyy.c zzz.c objs=$(sources:.c=$(new))

  • Wrapping \NewEnviron into \newenvironment fails

    - by o_O Tync
    Hello! I am trying to wrap an environment created with \NewEnviron (package 'environ') into an old good \newenvironment: \NewEnviron{test}{aaa(\BODY)bbb} \newenvironment{wrapper}{\begin{test}}{\end{test}} \begin{wrapper} debug me \end{wrapper} However, this gives me a strange error: LaTeX Error: \begin{test} on input line 15 ended by \end{wrapper}. LaTeX Error: \begin{wrapper} on input line 15 ended by \end{document}. If I replace \NewEnviron{test}{aaa(\BODY)bbb} with \newenvironment{test}{aaa(}{)bbb} — everything works as expected! It seems like \NewEnviron fails to find its end for some reason. I'm trying to do some magic with 'floatfig' wrapped into a \colorbox so I need a way to convert \colorbox to an environment and wrap it into another one. I can define a new command but it's not a very good idea. Thanks in advance!

  • Make a function which returns the original list except the argument

    - by Alex
    I want make a function which takes a list of string and a string and returns NONE if there is no string in the string list, otherwise it returns SOME of the list of string which is the same as the original list of string except it doesn't contain the initial string (pattern): fun my_function (pattern, source_list) = case source_list of [] => NONE | [x] => if pattern = x then SOME [] else NONE | x::xs => if pattern = x then SOME (xs) else SOME (x) :: my_function (pattern, xs) (* this is wrong, what to do here?*) val a = my_function ("haha", ["12", "aaa", "bbb", "haha", "ccc", "ddd"]) (* should be SOME ["12", "aaa", "bbb", "ccc", "ddd"]*) val a2 = my_function ("haha2", ["123", "aaa", "bbb", "haha", "ccc"]) (*should be NONE*) val a3 = my_function ("haha3", ["haha3"]) (* should be SOME []*) I'm confused by the 3rd case: x::xs => .... What should do there? Note that I'd like not to use any sml library function.

  • A submenu (`ToolStripMenuItem`) does not show automatically.

    - by czuk
    I have encountered strange problem with a three-level context menu. In some situation the sub menu does not show automatically. I have following structure of the menu: * AAA - level 1 * BBB - level 1 * CCC - level 2 * xxx - level 3 * yyy - level 3 * DDD - level 2 * zzz - level 3 * vvv - level 3 I start from a menu with two option AAA and BBB. After I move the cursor over BBB the second-level menu appears with two other options CCC and DDD. So far OK. Now, when I quickly move the cursor over DDD the third-level sub menu does not show up, but when I move the cursor back to CCC the sub menu shows up, and when I go back to DDD then the sub menu also shows. Why it does not show at first time? Have you ever encountered such a problem? I fixed the problem with MouseEnter and MouseLeave events, but I still wonder why it does not work properly without the events.

I would like to use ggplot to plot the barplot mean of the time series of val1,val2,... for each type. One plot for each type except for ccc and ddd that should be considered as one type, so for this I should first sum up the value, then take the mean, then plot). So three plot at the end. Thanks for advice.

  • change label text from a VB6 binary (not source code)

    - by Jun
    Hi, we have a VB6 binary executable that comes with no source code. And we need to change the label text for that VB6 application from "AAA" to "BBB". Is there any way or tools that can do that? The closest tool I can find right now is microsoft UISpy, it can read all the other elements but not the label. I hope there is a tool that can change the resource in the .exe so that the label "AAA" will read "BBB". Or is it possible to write a wrapper application, it will launch the .exe, examine the application screen for "AAA" and change that to "BBB"? Thank you for your help!
