Visual Studio C++ GUI Forms

[Ovisss4]

Hi there so I need some help which C++ GUI programming. So this semester we jumped to GUI and all we got is how to add button label and etc... and jumped to vector, dynamic array and etc... So now i need to make program which GUI. So what i'm trying to do is Load file and there are label which contains text("No files loaded") and needs to read file get data and add file name in label, but i get error and don't know why.

 

Here is the code:

private: System::Void atidarytiFailaToolStripMenuItem_Click(System::Object^  sender, System::EventArgs^  e)	{		openFileDialog1->DefaultExt = ".txt";		openFileDialog1->Filter = "Text files";		if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK && openFileDialog1->FileName->Length > 0)		{			String^ dfv;			dfv = openFileDialog1->FileName;			richTextBox1->LoadFile(dfv, RichTextBoxStreamType::PlainText);			string dfvs;			StringTostring(dfv, dfvs);			Duomenys(info, dfvs);			label2->Text = dfv;		}	}

And maybe someone knows where i could find more info about GUI ?

OK solved the error seemed that i attempted to read different file, which made my data reading function to go nuts. And another question is it possible to spawn labels on code or should i create empty labels and then add text then different files load.

Should be. I haven't used C++ but using C# it would be done like so.

Label label1 = new Label();// fill out any properties for label1this.Controls.Add(label1); // "this" being the GUI form

It might be similar for you seeing as it looks like you're using C++ with the .NET framework.

You wouldnt want to allow the user to create their own labels but you could create a bunch for what you need and change the label property "visible" to false and then true when you need them.

OK so i used rich text box. Now i have one question. So i get data in to container. So i want a button which clears its data. But not sure how probably which destructor I guess but how to run destructor in form 

 

Here is the code:
