Oh, I see. Then perhaps SetActiveView is what you need.

Dynamic defines?

Is there a way to create c++ variables out of literals read in from a file? I want to read in a file that has a line that reads CONNECT. I want to make a variable named CONNECT and have the value of 2000 so I can use it in a switch/case statement. I want to be able to create these variables dynamically so that I can eliminate hard-coded values.

Any help will be appreciated,

Ray Unsure | :~

not at run time.

at compile time you can use the "##" construct to glue two strings together in a macro.

There's no way to do it at run-time, but you can go with something like a hash map, where you associate a name ("CONNECT") with a value (2000). Check out the std::map class, which you can define like this:

#include <map>
using namespace std;
 
typedef map<CString, int> FileVariables;  // assuming all values are integers
 
FileVariables vars;
fv["CONNECT"] = 2000;
fv["DISCONNECT"] = 4000;
 
// Then you can use it like this:
if (fv["CONNECT"] > 10000)
   ....

How to reload the values in the resourse file at runtime?

Let's say I have changed the captions of some buttons in my MFC dialog application at runtime. Is it possible at some time later to reload the original names from the resource file without restarting the application and how?

I suggest you using a sting table and then restore the names with LoadString().

DTMF Decoding? (or FFT code)

Simon Steele25-Feb-03 4:04

25-Feb-03 4:04

Has anyone seen any good example code for doing DTMF decoding? I know that TAPI can do this with a modem, but I need to do it with a standard wave stream - it's a non-telephony application.

If you don't, then perhaps you could point me in the direction of some good FFT code or a library of some sorts.

Thanks in advance,

easiest way is to open the gif in something like paintshop pro, then copy it (edit|copy type copy i mean), and paste into the VisStudio dialog editor. thats what I do, anyway.

#include <beer.h>

Rescaling the image ends up distorting it. I am using Microsoft Photoeditor.

I'm definitely doing this the wrong way but don't know why.

Thanks
Nitin

You are doing it the right way. When you rescale the image in Photoeditor, you have to ensure you keep the aspect ratio the same, otherwise you will end up with a distorted image.

example:
the image you have is 400x800 pixels. This is a 1:2 ratio, so when you resize the 400 to say, 200, you then have to change the 800 by the same aspect ratio about, which is 50% here, so you would end up with a new image size of 200x400, which is smaller but still maintains the same aspect ratio and should not distort the image.

I hope this helps!

I fail to open an ACCESS mdb file by DAO unless i convert the mdb file to old version.
How can i open the original database (the one from which i converted to old version)?

sounds like you need to update your DAO library on that machine. I think it might be wrapped in MDAC now.

choosing a database

Hi,

I've heard of many databases : Access, SQL Server, Interbase, Oracle, MySQL, etc...

Now, I have to choose one, and I don't know how to decide. I guess to be able to choose, I need to know what are my needs. Well, I need a portable database, efficent, fast, reliable, etc....
How can I decide which one is the best (okay, I already know I won't use Access, I need a real database server) ?

Any suggestions welcome !
Thanks !
Jerome
