Just type & before the key you want to use as mnemonic for that button.
For example: Butt&on will have the o key as mnemonic.

thanks. I am using the studio.net. How to add mnemonic? In the property session, there is no such choice to add/change mnemonic.
Can I add an (text) accelorator description in my .rc file like this?
Exper_Menu ACCELORATORS
{
"1" IDC_FIRST
"2" IDC_SECOND
}
Thanks

I have some text and I would like to draw a black outline around it. How does one do this? Do I use pens or do I use another font with differant attributes?
I tried the latter and I got weird results.
Could someone please help!

I have a C++ client app. that will be used publically within and outside the U.S. What type of encryption can be used to encrypt the packets between the client and server(Win2000)?
|
|
|
|
|
i think 54-bit DES or lower is OK. but, even then, i think you will have to ask the US Dept of Defense. last i checked (a couple of years ago) every application needs to be approved individually.
maybe Bush relaxed the rules on crypto ...

I was thinking of using the Rijndael (symmetric block cipher) for packet encryption. Am I right in thinking that I have to use something like RSA(public key) to transmit the key to the client at the start of the session since symetric cyphers require the same key at both ends?
Couldn't find any examples of this on CP.

|

Yes, you will need to use some sort of public key encryption to securely pass the session keys between the server and the client.
Then you can use the symetric encryption between the two.

I am spawning a CDialog from an MFC MDI view.
I am presuming that I will put in stuff (RECT rcNormalPosition) from the struct in the registry when I shut off the app:
typedef struct tagWINDOWPLACEMENT {
UINT length;
UINT flags;
UINT showCmd;
POINT ptMinPosition;
POINT ptMaxPosition;
RECT rcNormalPosition;
} WINDOWPLACEMENT;
Q1. I am not clear about what to store in ptMinPosition, and the corresp. maxpos. CAn I leave these NULL?
When I run the app gain, I want this CDialog excatly where it was and same size etc when I last shut down the app.
Q2. So in what part of the MFC code shall I make the CDialog show up again
( I'll do pDlg->Create() and then MoveWindow to rcNormalPosition ....correct? )
THese CDialogs are not within the mainframe....so will rcNormalPosition put them at those positions from the
computer screen origin? I'll have several CDialogs and I need them to reappear at the precise positions the user chose before he quit.
Appreciate your help,
ns

I am optimistic I'll be able to figure out your class and use it<> only question is this:
The CDialogs were spawned by an MFC MDI view menu. SO now when the app is rerun, its the MDi part that will be running. I was reading the registry in pre-create of the mainframe so far to restore the mainframes status quo. Shall I in this same place do the modeless create for the CDialogs? I feel intuitively (thats a laugh - I am not old enough in this stuff for gut feelings!!!!) that this isnt t he place. SO maybe I should in the OnInitialUpdate of the view do something like:
If the registry says there are nonzero number of CDialogs information saved, then do
i =0; i < nCDialogs; i++
restore( what instead of the this that you have in your docs?)
You do a restore (this) but what should I restore? What should I have saved in my mainframe OnDestroy trhat I can use here?
DO you agree that I need to restore in OnINitiaUpdate?
Appreciate your help,

I have a 4 character array which contains a hex number (ie. 02D1). I want to output the characters matching \x02 and \xD1 to my file. It works fine if I hard code it as "\x02\xD1", but the problem is the values are variable.
Anybody know of a function similar to CHR() that would handle this for me?

Can't you use CString.Format, or an ostringstream to build the string with the \x values in it ?

I tried using format(), but \x requires a number after it.
Anyway I ended out with the following:
<br />
CString sHeader;
int nHigh; <br />
char sHigh; <br />
nHigh = strtol(sHeader.Left(2),NULL,16);<br />
sHigh = nHigh;
Seems to work fine so far.. Thanks for your help.

Hi.
I am working on a project that includes downloading data from webservers. There is a problem. Some webservers rejects the program request for data. In one example, the webserver responded with an error that the request was ignored because the client (program) is trying to access the data from another server. In terms of web browsers, this is like clicking on a link at www.google.com to download data from www.gamespot.com.
To my understanding, the server is incorrect because the program is communicating directly to the server just as a web browser does. I would like to know how do web server such as the example know where the client originally found the link to the data?
In the example above, is there any HTTP 1.1 code that I need to add to the request so that the server to process the request?
Thanks,
Kuphryn

This is from RFC 2616 which is HTTP 1.1.
Take a look at section 14.23 and 14.36. I think 14.36 is the key here. If I remember correctly, many servers use the "referer" field to know if content such as jpgs are being requested from pages hosted locally or from general requests from other websites. Lots of photo posting services do stuff like this so you can't store 1000 images on their site and then reference them from EZBoard.

Okay. I have tried both solutions, but none worked. Here is an example of the request.
-----
/GET http://visualparadox.com/images/no-linking-allowed/coloroncall800.jpg HTTP/1.1
Host: visualparadox.com
Referer: http://visualparadox.com/wallpapers/coloroncall.htm
Accept: text/plain, text/html
Accept-Language: en-us
Accept-Encoding: gzip
Connection: Keep-Alive
-----
Again, the request above does not work. Here is one website I tested use to test the request.

I am using the Create() function to create a bunch of CEdits in a CFormView derived class.
my problem is that as i tab through the fields they are not selecting the text in the field. they normally automatically highlight the text when the field gains focus.. it was the other day, but now its not.. any ideas?
still a newb.. cut me some slack :P

What was different the other day? Has someone else added an OnSetFocus handler? It may help to compare your source file with a version from when it did work. Hopefully you can do that and see what changed.

For an application we are developing we found that the first operation was taking an extremely long time on Windows XP. Initially we though it was a problem with our program, but later we found that even Explorer showed the same slowness.
Just reboot to XP, right clk on the large file and take Properties. The properties box won’t come for several seconds and the larger the file, the longer will the delay be. Google searches showed that there are several others who have faced similar issues. What is strange is that this is only for the first read, for further reads this problem is not there.
In our application the size of the file might go up to 1 Gb or above and might even be read on an USB device. In such a situation any extra delay is really an absolute problem for us. In fact we also tried taking the cmd prompt and renaming the file. The first rename took several seconds for a 10 Mb file, but further renames were immediately done.
We tried to open/close the file from another app, seek to end of file, read from the file, get file size etc… but all that still does not prevent the slowness when you simply try to take file properties from explorer. Is this an XP issue, if so is this a known bug? Any idea what really happens? Any fix?
Two very important points, this bug seems to be random (but only on XP, never happened on W2K). Sometimes the first and following operations work very well without delay. And secondly, this seems to concern only exe file (even if the extension is different).

Um... doesn't that make sense ? The bigger the file, the longer it takes to parse, but Windows also builds a cache ?
XP is the first OS that natively looks for .NET executables and handles them differently. Might that be part of your problem ?

Nish - I don't think it's anything specific to Windows XP - I've noticed the same phenomenon on Windows 2000, especially with files on network drives... Think about it, for some files where there's more than just size & file times (like executables, where the version is shown in properties), Windows pretty much has to read in the whole file to get at the relevant bits...
