View 1 Replies View RelatedBasically am trying to reference a method in a my Form1 class into another class. So far I have tried multiple different methods to try and access the method but have not managed it so far. Both classes use the same namespace. The part of my form class that I am using are as follows:
public class Form1 : Form
{
IContainer components = null;
private ButtonPanelThread p1, p3, p4;

I have a label on my main form. When I menu select my settings form, I make a change to the label text on the main form but the label text does not update with the new text.
So here is my code in my settings form:
MainForm frm = new MainForm();
frm.paintMainFormThemeTitle(logoText); // updates the main form label
I may not fully understand the new instantiate key word, but doesn't this create another, new copy of my main form to operate on? And isn't that why I can't see my label text change on my main form that is previously in view?
All of the examples that I have been able to find show using this new key word to be able to access a component on another form. But to my understanding, I'm creating another, new form.
I am a newbie to C++ and VS ++. I have created a windows form application by dragging and dropping button, label..etc. i wish label text to be appeared as return value from a function. The function returns ' const char* '.how this returned string pointer can be used to display label text.?

This is more of a Application Design question, Let's say I have Form1(Login), this is opened from Program.cs, when the user enters details, the Event Handler makes a instance of a class, adds the data and stores the instance within Program.cs class.
So the best thing to do here, is to close the Form1(Login) and open Form2(Main) via Program.cs so that I can send the List<Login> object with my Login instance objects to said form. This form will remain open throughout the applications use as it's like the main GUI for all the programs functions.
When I close this form, I may want to save some information before the application is terminated, so I may as well store the Login instances in Program.cs anyway.
Main stepping stone: Multiple (usually around 3 max) users can login this system if need be, which will mean closing Form2(Main) and then opening Form1(Login) so that once Form1 is closed it can recreate the From2(Main) form and pass the new List<Login> to that form.
What's the best way to do this, at the moment i'm creating the Form2 instance like so:
//....
//Detect the Login form being closed
loginForm.Closed += new EventHandler(OnLoginClosed);
//...
//Open the main form when the login is closed
private void OnLoginClosed(object sender, EventArgs e)
[Code] .....
This seems like it will work and do the job, but is there a better and cleaner way? The List<Login> will be passed to Forms which are created via Form2(Main) as this information will be needed. It's just that ive been told not to use Forms for too much data containment.
How to access a method from a .h file in another .cpp file
Code:
// main.cpp
#include <iostream>
#include "inc/one.h"
using namespace std;
int main( ){
School Tadd;
Tadd.AddTeacher(1);
return 0;
[Code] ....
When I compile , i am getting the below error
In function main:
undefined reference to `School::AddTeacher(int)'

I have a form with 2 text boxes (Email and Password)
The user fills in the text boxes and clicks on the Log in button. The code behind the log in button does the following, First connects to a table (Users) in phpmyadmin. Next runs a SQL query (SELECT * FROM `users` WHERE Email = '" + sEmail + "' AND Password = '" + sPassword + "'") sEmail being the variable created from the text entered in Email text box and the same for password.
Next if the record count == to 1 it opens up the main menu form and if the record count == 0 it fails and the user does not get to the main menu.
All of the above is fine and working however what I want to do is take over a variable from the log in form to the other forms.
The code is below for the sign in button as all my code is behind that (I think this may be where I'm going wrong).
public partial class WelcomeForm : Form{
public static string connStr = "server = localhost; " +
"database = ppw5; " +
"uid = James; " +
"pwd = buster;";
[Code] .....
And the Main menu form where I'd like to take a variable over with me, lets assume the variable is the UserID from the database table that I pull from the dTable I created.
public partial class MenuForm : Form {
//Call the CloseProgram class and create a new method called ClassClose.
CloseProgram ClassClose = new CloseProgram();
WelcomeForm User = new WelcomeForm();
public MenuForm() {
InitializeComponent();
[Code] .....
Alright, so I'm making a windows form with a few hundred buttons, and one button will change color based on data the program receives over a socket. This is what I have, and it kind of works, but I don't want to have to make another if statement for all 260 buttons.
void hitmiss(std::string u){
std::string^ ind = reccdata2();
if (u == "button6"){
if (ind == "1"){
this->button6->BackColor = System::Drawing::Color::Red;
this->textBox2->Text = L"hit";
[Code] .....
What I want to do is make it more like
void hitmiss(System::String^ u){
std::string^ ind = reccdata2();
if (ind == "1"){
this->u->BackColor = System::Drawing::Color::Red;
this->textBox2->Text = L"hit";
[Code] ....
But it returns the error that u is not a part of Form1.
What I want is just to make a validation of the users and passwords already set within my array and go to the other form. By the way this form I already made it my start up form on program.cs with the same command I am trying to back to MainForm.
void Button1Click(object sender, EventArgs e) {
string error = "denied";
string[,] usrpass = {{"User1", "pass1"}, {"User2", "pass2"}, {"User3", "pass3"}, {"User4", "pass4"},
{"User5", "pass5"}};
[Code] .....
I have a program which when a button is clicked on Form1 it runs a vision system operation on an image in a window on a Form1. There are also other buttons on the Form1 which can change things like threshold levels so the inspection can be run again with different settings. It all works fine but I want to change it to remove the buttons from Form1 so that when the user clicks on a button on Form1 it opens up another form, Form2, and all the buttons which were on Form1 are now on Form2 and the image analysis should run on Form1 when the buttons are used on Form2. I have taken over all the code from Form1 to Form2 and I'm trying to make this happen by creating a new oject on Form1 which calls a method on Form2 which contains the code which was in Form1 and called when the button was clicked on Form1 - not working!! I have a constructor in Form2 but I think I have become monumentally confused.
This was the code which was on Form1 when the inspection button was clicked.
private void cmdInspectOnce_Click(object sender, EventArgs e)
{
iReturn = VisionSystem.InvModeSet(IpeEngCtrlLib.I_MODE.I_EXE_MODE_ONCE);
if (_imgEngines!=null && _imgEngines[0]!=null)
_imgEngines[0].cmdInspectOnce();//InvModeSet(IpeEngCtrlLib.I_MODE.I_EXE_MODE_ONCE);
}
I have 3 Windows Form: frmMain, frmFirstForm, and frmSecondForm.
frmMain is the form that will load when the application is started with 2 tabs to access frmFirstForm and frmSecondForm.
Here's my problem:
After making a selection from a combobox on frmFirstForm, I would like a datagridview header to change based on the selection made. Here is a list of items on one combobox: Item1, Item2, Item3, Item4. When somebody chooses Item one, the header on the datagridview on frmSecondForm should display: JohnItem1, PaulItem1, BradItem1 and so on. Those items are not part of the comboboxes, but they will be shown as header text on the datagridview on the second form either automatically or after clicking OK from frmMain. There's no OK button on frmFirstForm, but on frmMain.
The only code I have right now is the if statement on the form load on frmSecondForm. Here's what I have:
private void HeaderTextLoad() {
if(comboboxonfirstform.text = "Item1") {
datagridview1.Columns[0].HeaderText = "ItemJohn";
datagridview1.Columns[1].HeaderText = "ItemPaul";
... And so on.
}
}
I have a form that has been loaded and I click on a quit link to terminate my app but then I display a messageBox to ask the user if they want to save a file before quitting. When the messageBox pops up, another new instance of this form displays. What causes this and how can I prevent it?
