modeless dialog closing - C / C++ / MFC Discussion Boards

Hello everybody,

Does anybody know how I can use the method ExecWB of the WebBrowser control for opening a file on the local machine:

ExecWB(OLECMDID_OPEN, OLECMDEXECOPT_DODEFAULT, ?, ?);

I don't know the use of parameters 3 and 4.
I Also don't want to use Navigate method because of the download prompting.

thanks in advance
Roozbeh.

hum, i think you need some basic notions about C++.

in such declaration syntax, operator & represent the declaration of a reference, and operator * represent the declaration of a pointer...

in you example, getline get as paramater a pointer to char (buffer), an int (length) and a char (terminal_char). it returns then a reference to an istream instance.

istream& means a reference to an istream object.

You have to notify the Parent by sending Some Sort of Custom Window Messages! look for WM_APP and WM_USER messages in your locla copy of MSDN

When I compiled my project,I got the error messages below:
Frown | :(

<br />
fatal error C1001: INTERNAL COMPILER ERROR<br />
(compiler file 'msc1.cpp', line 1786) <br />
Please choose the Technical Support command on the Visual C++ <br />
Help menu, or open the Technical Support help file for more information<br />

I have checked this error number in MSDN,but I can't solve this problem.

So can anybody here do me a favor?
Appreciate. Smile | :)

Oh,by the way,my environment is VC6.0.

The compiler cannot generate correct code for a construct, probably due the combination of an expression and an optimization option. Try removing one or more optimization options and recompiling the function containing the line indicated in the error message.

In your eyes,"CS"just means C sharp.
In fact,it can have many kinds of explanation.
For example,Computer Science.

I love C Sharp.
And I love c++ too.
C sharp and C++ don't mind sharing my loves with each other.

hei,guy,maybe you can give me some advice on my problem?

a blowfish decrypt/encrypt related question

hi guys,
currently i am working on a server/client which uses blowfish to encrypt/decrypt the message protocal.
the problem i am facing is i was trying to implement the blowfish that George Anescu provided at (http://www.codeproject.com/cpp/blowfish.asp)

but the result doesn't looks right.
encrypted
0xEA,0xC4,0x60,0x77,
0x14,0x6A,0xBC,0x23,
0x3B,0x36,0xFC,0x34,
0xA0,0xDD,0x82,0xAF,
0xD6,0x9E,0xAB,0x38,
0x05,0xB1,0xE6,0x98,
0x0D,0x2D,0x41,0x44,
0x78,0x22,0x29,0xB6,
0x76,0x62,0x4A,0x79,
0xFE,0x01,0xED,0x06,
0x51,0xE7,0x19,0xE1,
0x35,0x1E,0xAA,0x19
should be decrypted to something like this
0x00,0x74,0x6f,0x72,
0x75,0x6e,0x65,0x00,
0x00,0x00,0x00,0x00,

0x78,0x16,0x64,0x6e,
0x00,0x00,0x00,0x00
