DWORD to string

[JL8843]

Does anyone know how to convert a DWORD to a string, or char* or char[], or CString etc.

What I am trying to do is read a DWORD value from the registry and put its value in an edit box in a MFC Dialog. And then when the user clicks OK, I'll take that value they typed into the edit box(if they changed it) and put that back into the Registry.

I found out how to go from char* to DWORD but I can't figure out how to go the other way around so when I first read that value from the Registry I can update the edit box with it.

Basically I am trying to display a DWORD value in an edit box.

Thanks

Take a look at these FAQs.

Thanks for your responses.

I guess I have to convert the DWORD into an int or decimal representation first for it to display correctly in the edit box.


Right now it is displaying 3i in my edit box.

How would you go about converting the DWORD value into a decimal value?

DWORD is nothing by 'typedef' for unsigned long. It hold value within its range.
It is upto programmer how to represent it, how to store value in it - decimal, hexa decimal or octal format; or to use it in calculations or as return value of some expression/function.

Can you be more specific, what you want to achieve?

Either with the C runtime function ltoa():

#include <stdlib.h>

char buffer[32];
ltoa((long)dwValue, buffer, 10);

Or with the WinAPI function wsprinf():

#include <windows.h>

char buffer[32];
wsprintf(buffer, "%d", dwValue);

Did you read FAQ cilu suggested?

Did you read FAQ cilu suggested?

Yes, I think that I am now able to load the DWORD value into the edit box.

I am still confused however with writing back to the registry.

How do I go about converting an int to a DWORD? Is this just a simple cast?

Yes, it's a simple cast between two numeric types. DWORD is actually defined as unsigned int.
