C# :: Change Form Control Properties From User Control
May 24, 2014I have researched quite extensively, experimented, and still cannot seem to change the properties of a control on an active winform from a user control.
So I have a user control which populates each dynamically added tab page in a tab control.
I have a textbox in the user control which I would like to type in, capture the text_change event, and change the text of the label in the winform.

C# :: Login Then Close Form And Open Main Form
Aug 25, 2014This 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.

C# :: Sharing Variables From Login Form To Another Form
Mar 10, 2015I 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();

C++ :: Using Variables To Access Objects In Windows Form
Dec 4, 2014Alright, 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.
C# :: Calling Method In One Form From Another Form?
Dec 6, 2014I 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);
}
C# :: Selection From 1 Form DatagridView On Second Form
Sep 5, 2014I 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.
}
}
C :: Input From User As Char And Output In Hex Form
Sep 9, 2014I'm trying to write a program that takes input from the user (thats a char) and outputs it to the monitor in hex form.The program is meant to continuously take input from the user then output to the monitor in hex form until an EOF is detected this triggers the program to close.The following code does this except that I get a lower case 'a' at the end of each output.I think the 'a' has to do with the enter key and if that is the case how can i tell the program to ignore this input from the user.
Example: input from user: ABC output to monitor: 41 42 43 a
Code:
#include <stdio.h>
int main(void) {
char myChar;
while(EOF != (myChar = getchar())) {
printf("%x ",myChar);
}
system("pause");
return 0;
}
Visual C++ :: Allow User To Enter A Value As C String In Certain Form
Oct 14, 2013My program was to allow the user to enter a value as a C string in the form: xxx,xxx,xxx,xxx,xxx.xx, where x can be any digit. Well, so far here is my attempt. I think the question is, would I have to implement a switch statement for the digits, the comma, and the decimal, so that when a user inputs, let say 52,000.00 the switch statements would read the 1st digit, checks for decimals/commas and if not, proceed to read 2nd digit, and repeat?

Visual C++ :: Passing DDX Control Variables Between Dialogs (Parent->Child)
Jul 19, 2013I have a main dialog which has (DDX?) controls for the user. eg a slider, and a combo box.
Previously, an image adjusted by these controls was in the same dialog.
I need to put this image in a New, separate dialog but it still must be controlled by the slider and combo box on the main dialog.
My question is how can I pass the control's variables between the dialogs? I have, say,
Code:
//MainDlg.cpp
DDX_Control(pDX, IDC_ComboBrightness, m_Brightness
I was told that I could do something like:
Code:
//ImageDlg.h
public:
ImageDlg(CWnd* pParent = NULL, CComboBox m_Brightness); // standard constructor
But I get errors including: Missing default parameter for parameter 2
I also need to pass the image array, is that perhaps the same method?

I have overwritten OnOK and OnCancel in the main dialog so the edit control never receives notifications for Escape or Enter whether in OnChar or PreTranslateMessage and I would like to delete the CEdit control after updating the CListCtrl on Enter. What can I do? I have rewritten this code many many times over the past 4 days and nothing is working.
