Answer 1

how to assign the text of a textbox to a character type of variable in windows form application on vc++???

     

Do you mean just

textBox->Text = L"Some text";

?

But why are you asking a WinForms question in the MFC/ATL forum?

The Text property can be stored in a String instance.
Then you can extract the first character (if this is what interests you) and assign it to a character variable.

Two things here
 
1. char is a single character, not a string of characters
 
2. Strings in .NET use 16-bit characters (wchar_t in C++) not 8-bit (char in C++).
 
But as Giovanni suggsts, it is best to use System::String to store text
 
String^ str = textBox->Text;

Answer 5

the thing is, i am browsing a image path through a dialog box in windows form application in vc++,then i need to work with that path.

this path should be of string type not String^ for my work to proceed..help..

Answer 6

How about

char *string;

strcpy(string, textBox->text);

Retrieving Text

To retrieve all text from an edit control, first use the GetWindowTextLength function to  determine the size of buffer needed to contain the text. Next, retrieve the text by using the GetWindowText function.

Windows forms are part of the .NET library, which has its own classes for dealing with the file system (see System::IO namespace).
 
But even if you want to use the standard Windows ways of accessing the file system, you should be using wchar_t strings for the file name, not char strings, because all recent versions of Windows use UTF-16 as the native character set.
 
Go to
 
Project properties->Configuration Properties->General->Character Set
 
and make sure that "Use Unicode Character Set" is chosen.

Answer 8

How about
 
char *string;
 
strcpy(string, textBox->text);

This cannot work because
 
(a) no memory is allocated for "string"
 
(b) the OP is using WinForms
 
(c) It should be textBox->Text, not textBox->text
 
(d) The Text() method returns System::String^, which cannot be used with strcpy.
