please help me.

"Binary data" and "text control" doesn't seem to match very well. Do you mean you want to edit it like a hex editor? — Some programmer dude

There are two ways of doing this.

If you already have the format of the binary data, just output the structures with field names and values:
```
Data:
    Field1: Value1
    Field2: Value2
```
The above can be from a structure like:
```
struct Data
{
    int field1;
    int field2;
}
```
You can format the data like a hex editor, something like this:
```
0000 xx xx xx xx xx xx xx xx ........
0008 xx xx xx xx xx xx xx xx ........
```
The first number is the offset into the binary data, each "xx" is a byte in hexadecimal, and each "." is a printable representation of the corresponding byte (if it is printable, otherwise the custom is to print a dot.)

@yogeshpatel You format it as a string like in my answer, then put the text from that string into the text control like for any other text. For that you have to read the documentation for e.g. CStatic or CEdit if you are using MFC.
