I’m trying to create my own error window for the project I am working on. When I show my error window I have no way to pass the error message, and user message to the Error window because the ‘ErrorMessage.Text’ cannot be seen in the classes I make.
I went into the form designer generated code and tried to make the TextBox static, but that just breaks things. Can I make a TextBox public / static so I can change it from another form?
- How do I make a TextBox Static Public so I can manipulate it across other forms, or is there another method for doing this?
EDIT:
Okay, for more information…
I have my own Form created. It is called ‘formErrorWindow.’ I need to display the form that i’ve pre-designed with the message set from another form. The only way I can do this is if I create a Function in the windows designer area for the form, and I set the variables with ‘this.errorMsg.text = error.’ The only way I can see that function is if I set it to static. If I set the function to Static, when I try and put ‘this.errorMsg.Text = error’ I get this error: An object reference is required for the non-static field, method, or property.
Here is what I’ve attempted:
namespace LCR_ShepherdStaffupdater_1._0 { partial class formErrorWindow { /// <summary> /// Required designer variable. /// </summary> public System.ComponentModel.IContainer components = null; /// <summary> /// Clean up any resources being used. /// </summary> /// <param name='disposing'>true if managed resources should be disposed; otherwise, false.</param> /// protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> // ********* HERE IS THE FUNCTION THAT IVE ADDED BELOW. THIS WOULD WORK BUT.... ********* public static void showError(string errorTitle, string usrMsg, string errorMsg) { formErrorWindow errorWindow = new formErrorWindow(); errorMsgItem.Text = errorMsg; errorTitleItem.Text = 'Error! : ' + errorTitle; usrMsgItem.Text = usrMsg; errorWindow.ShowDialog(); } // ********* HERE IS THE FUNCTION THAT IVE ADDED ABOVE.

How do I get that to compile and do what I want it to do WITHOUT that error I keep getting: An object reference is required for the non-static field, method, or property.
Yes! have a function made public that can receive this text:
and have the function update the textbox from there.
don’t mix UI with logic.
