I have this code :

VB

this.toolStripCategories.Location = new Point(3, 138);
            this.toolStripCategories.Name = "toolStripCategories";
            this.toolStripCategories.Size = new Size(258, 25);
            this.toolStripCategories.TabIndex = 6;
            this.toolStripCategories.Text = "toolStrip1";
            this.tsbAddCategory.DisplayStyle = ToolStripItemDisplayStyle.Text;
            this.tsbAddCategory.Image = (Image)componentResourceManager.GetObject("tsbAddCategory.Image");
            this.tsbAddCategory.ImageTransparentColor = Color.Magenta;
            this.tsbAddCategory.Name = "tsbAddCategory";
            this.tsbAddCategory.Size = new Size(33, 22);
            this.tsbAddCategory.Text = "Add";
            this.tsbAddCategory.Click += new EventHandler(this.tsbAddCategory_Click);
            this.tsbEditCategory.DisplayStyle = ToolStripItemDisplayStyle.Text;
            this.tsbEditCategory.Enabled = false;
            this.tsbEditCategory.Image = (Image)componentResourceManager.GetObject("tsbEditCategory.Image");
            this.tsbEditCategory.ImageTransparentColor = Color.Magenta;
            this.tsbEditCategory.Name = "tsbEditCategory";
            this.tsbEditCategory.Size = new Size(31, 22);

And it keeps giving me this error.

Warning 1 The variable 'componentResourceManager' is either undeclared or was never assigned.

I dunno what am doing wrong. Please help

What is not working? Does it give any error after you added the code that I gave you?

Solution 1

That looks like a Typo. Try ComponentResourceManager with a capital C at the front.

Hope this helps

yes..
ComponentResourceManager is a class and as per the Naming convention that .Net Framework is follow, for the class name they use Pascal naming convention.

Wayne it gives off an error
An object reference is required for the non-static field, method, or property 'System.Resources.ResourceManager.GetObject(string)' if ts a small c then the one above is a warning

Warning?! It should give you a compilation error!

As Wayne already said, ComponentResourceManager is a class and starts with a capital C.

GetObject is an instance method of ComponentResourceManager. You need an instance of the class to access this method, which you seem to have not created.

Add this line:

C#

ComponentResourceManager componentResourceManager = new componentResourceManager();
//or the other overload passing Type as a parameter

now this line makes sense,

C#

componentResourceManager.GetObject("tsbAddCategory.Image");

For more information about the class, check the MSDN link - ComponentResourceManager Class[^]

Hope this helps! :thumbsup:

Here's the error it gives :
Error 44 'ConsultingLeadsPro.MainForm.componentResourceManager' is a 'field' but is used like a 'type'

Patoh58 17-May-11 8:39am

private void InitializeComponent()
{
ComponentResourceManager componentResourceManager = new ComponentResourceManager(typeof(MainForm));
this.btnSearch = new Button();
this.btnStop = new Button();
this.cmbSite = new ComboBox();
this.dtpLowDate = new DateTimePicker();

Ankur^\m/ 17-May-11 8:41am

I was just going to ask you to paste the code where error is occurring. Let me check.

Ankur^\m/ 17-May-11 8:44am

ComponentResourceManager componentResourceManager = new ComponentResourceManager(typeof(MainForm));
I am afraid you cannot do that inside InitializeComponent() method.

Patoh58 17-May-11 11:05am

Ok! Where can i put it?

Ankur^\m/ 18-May-11 0:35am

You may put it in the constructor after the components are initialised.

Sergey Alexandrovich Kryukov 17-May-11 17:34pm

Sure, a 5.

I think i solved the errors as now the designer is showing but without buttons and objects. Thanx

Ankur^\m/ 18-May-11 8:06am

I saw your code. Buttons and object that you are talking about won't show because you were using the ComponentResourceManager class to design them. Just move that part to after Initialize Component code and it should work fine.
I will leave things to you now.
Good luck!
