c# - Public variable invoking incorrect result - 


public partial class thanglishtotamilgui : form {     public string anz;      public thanglishtotamilgui()     {         initializecomponent();     }             public void btnconverttobraille_click(object sender, eventargs e)     {         anz = richtextboxtamil.text.tostring();          gui.tamiltobraillegui c1 = new gui.tamiltobraillegui();         c1.visible = true;                 }  }

i need pass richtextbox (richtextboxtamil) content variable call anz.

i retrriving anz variable in other form form load event:

    private void tamiltobraillegui_load(object sender, eventargs e)     {         thanglishtotamilgui tt = new thanglishtotamilgui();         string apper = tt.anz;         richtextboxtamil.text = apper;     }

my problem: getting null values result. since if assigned values invoked correctly.

public partial class thanglishtotamilgui : form {     public string anz = "hai";      public thanglishtotamilgui()     {         initializecomponent();     } ...

here ans value passed "hai". requirement ever content in richtextboxtamil , pass public variable call anz. went wrong here please me.

thank you.

this problem:

thanglishtotamilgui tt = new thanglishtotamilgui(); string apper = tt.anz;

how expect apper ever other null? you're fetching variable freshly-created form, has never been shown, , has never had btnconverttobraille_click called on it.

presumably there's existing thanglishtotamilgui object somewhere, , that's 1 want fetch variable from. basically, 1 form needs know instance of other form.

(i'd suggest using property rather public variable, that's different matter. might not need have separate variable @ - declare property fetches richtextboxtamil.text.)

alternatively, pass relevant string constructor of new form:

public void btnconverttobraille_click(object sender, eventargs e) {     gui.tamiltobraillegui c1 = new gui.tamiltobraillegui(richtextboxtamil.text);     c1.visible = true;             }

then new form doesn't need know old form @ - only needs know text display.

(you might want pull out of constructor , settable property, it's same principle: code creating form pushes data, rather new form pulling it.)

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
