If I need to store state data from a modeless dialog box I usually pass a pointer to my CDocument and store it there. Otherwise when a button is pressed I send a command message to my main view window. This way the dialog can delete itself in the PostNcDestroy function without worrying about some function trying to look at data stored in the dialog class after it has been destroyed.

Iam doing MFC based project .MY project has a dialog box which contains the GRID control activeX control .
Now when i try to access that dialog ( which contains the grid) in the Visual studio .NET ,i get this message .
"The activeX control GRid control requires design time liscense".
I prepared the installation using WISE and installed in the same system in which it was developed .
But the same dialog box works fine in the EXE .

I need to launch a Vis Studio 6 C++ application that is initially minimised.
This is a Dialog-Based app.
How to do this?
Most of the time this app will run and exit in a few seconds, but I want user to be able to maximise it if runs longer and it is desired to watch app progress.
Much thanks in advance.

Your easiest option would be to progrmatically minimize it in OnInitDialog otherwise you will have to manually (text) edit your .rc file. I believe that is where it is stored. Unfortunately I have not used VC6 in quite awhile and I am currently working console based apps. Alternatively you could create an SDI app with CFormView and remove the tool bars etc.

Thanks Matt!

The easiest thing you can do is putting the following call at the end of your OnInitDialog():
BOOL CSampleDlg::OnInitDialog()
{
...
// Open the dialog minimized
ShowWindow( SW_MINIMIZE );
return TRUE;
}
That should do it...  Hope it will help you!

hi, all,
i have to move to unix, i really hate vi or pico.
is there a very good c++ tool (similar to VC++ in windows) in unix? what is that? which one is best?
i believe someone here is good in unix also.
thx

xemacs (and it's free) for editing. ddd for visual debugging (of core dumps).

I just use nano. But then again I am a windows programmer so I don't really do much unix work.

I personally used the editor (X)JED with Make, DDD and Qt professionally a couple of years ago. When it comes to IDEs comparable with Visual Studio, KDevelop must be the number one choice.

Hi,
I have embedded a windows media player 9 control in a CFormView of an SDI Appln. The default properties of the control in the resource dialog is set as
1) Play Full Screen - true
2) Auto Start - false
3) File Name - swiss.avi
4) Windowless video - true
5) Mode - None (No button controls)
In the code I trigger the AVI to play using
m_Player.SetUrl(avi_file); // avi_file is a variable that holds different AVI file names
m_Player.GetControls().play();
if (! m_Player.GetFullScreen())
m_Player.SetFullScreen(true);
It doesn't play the file in fullscreen when I run it. In fact it throws a blank error message box after it starts playing the file. I want to be able to switch the AVI files based on the key pressed by the user.
If I comment the Get/Set fullscreen code....it plays in fullscreen mode the first time and not after that. I don't know if this is a bug in windows media player 9 or am I doing something wrong ?
Also how do I maximize the windows media control to occupy the entire form view area when it starts up ?
Please help.
Thanks

I am trying to convert a NT-Service skeleton to UNICODE and I am stuck on one point:
USES_CONVERSION;
.
.
.
TCHAR chMsg[256];
.
.
.
printf(T2A(chMsg));
does not print out plain text instead I get the following on output in the command window(exact length may vary):
????????????????????????????????????????????????????????
My question is, is this the problem spot, if so how should i fix it, or is a conversion earlier in the code causing the odd output? I would greatly appreciate some ideas.

Try putting this code just before :-
_tprintf("%s", chMsg);
That way we know if the wide string is okay.

I did that but the only way I could get it to compile was to change it to
_tprintf(_T("%s", chMsg);
When i did this I got the same output.
vsprintf(T2A(chMsg), pFormat, pArg);
This is the only code executed on chMsg pFormat is LPCSTR and pArg is va_list

try "%S" instead of "%s"
-c

That didn't work either, It did add alot of special characters though

Hi,
I developed dll. I tried to regsvr32.exe to load the dll. I had a error message.
"filename.dll was loaded, but the DllRegisterServer entry point was not found"
what is problem of my dll?
Thanks.

regsvr32.exe is used to register COM DLLs and COM DLLs implement an exported function called DllRegisterServer for this purpose. regsvr32.exe simply LoadLibrary's the DLL and calls this function.

Hi, Nish
Do you have an example to implement this function? Any ideas are
appreciated.
Thanks

First of all is your DLL a COM DLL? If it is just a regular DLL you don't need it. If it is a COM DLL you should probably read up on COM.

I'm new to this, but I have a problem I can't solve, and could do with some help please.
I'm writing an encrypted chat program with VC++ 6, which uses the Winsock API. The encryption is provided by Peter Gutmann's cryptlib library.
The problem is that the encryption process outputs a void pointer to a binary string variable, and sockets as far as I'm aware take a pointer to a character string. The cryptlib documentation suggests using the S/MIME format but I'm not writing an e-mail client/server, I just want to send the data through a socket, something like this:
send( mySocket, encryptedDataBuffer, 1024, 0 );
Is there a way I can convert the binary into a character sequence, send that and then convert it back at the recieving end?
Thanks in advance.

Hi noxon
The 2nd argument for the send function is a const char* but remember that send was first written during the old C days and then a byte and a char were the same. This does not mean send can send only null terminated text strings. You can definitely use send to send binary text.The 3rd parameter specifies the number of bytes to send.
Regards,
Nish

Thanks Nish,
that has cleared up the question of whether I can do it or not. Im glad it was you who answered, it was your tutorial that got me off the ground with Winsock when I started writing the prog.
According to Microsoft void and char pointers are interchangeable without having to cast the pointer. So I'm giving cryptlib a NULL pointer to a character string like so:
char* encryptedDataBuffer = NULL;<br />
<br />
cryptPushData etc...<br />
<br />
cryptPopData( cryptEnvelope, encryptedDataBuffer, encryptedDataBufferSize, &bytesCopied );
But when i then use the code to send it on the Socket:
send( mySocket, encryptedDataBuffer, 1024, 0 );
The program just falls over (crashes), this same function works with a plaitext character string, so if I can send the binary, do you think I need to convert it to a hexadecimal representation of the actual binary, or am I missing something (quite possible).
Many thanks for help.
