c# - Declaring the value of a string based on a given text -


i'm quite new programming i'm gonna ask how can declare value of string based on object text.

so based on title.text of interface. going determine string value. here code tried:

 public mainmenu()     {         initializecomponent();         initializeoffice();      }     public string office;      public void initializeoffice()     {         if (officename.text == "accounting office")         {             office = "accounting";         } else if (officename.text == "registrar's office")         {             office = "registrar";         }

i using office string variable determine folder paths because both accounting , registrar offices have different directories. example:

using (streamwriter objwriter = file.appendtext("c:desktop\\" + office + "\\finished\\" + ticketnumber.text +".txt"))

can me out? seems string office shows "accounting" value if office text different.

additional:

if (chooseservice.text == "")                      {                      messagebox.show("please specify department.");                      }                    else                      {                        this.hide();                        mainmenu login = new mainmenu();                         login.show();                        login.officename.text = chooseservice.text;                      }

this content of officename fetched. chooseservice object combobox choices of different offices.

so problem here mainmenu form initialising title before setting string use determine 'office' should set to.

try this:

if (string.isnullorempty(chooseservice.text))   messagebox.show("please specify department."); else {   this.hide();   mainmenu login = new mainmenu(chooseservice.text);   login.show(); }

then modify mainmenu form so:

public mainmenu(string department) {     initializecomponent();     initializeoffice(department);  } public string office;  public void initializeoffice(string department) {     if (department == "accounting office")     {         office = "accounting";     } else if (department == "registrar's office")     {         office = "registrar";     }

this guarantee main menu class has information needs display correct value (or use set path). move initialisation of title out of constructor of mainmenu class , call initailiszeoffice string value chooseservice.text, either work bvut prefer code supplied. neater imo.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
