can you tell me more details
or even some samples?
Thanks

Well, you simply need to get a batch-file to do what you want (e.g. reading a text or playing a *.wav).
Then you can use "scheduled task" to start that .cmd at the time you want.
Please read the help about scheduled tasks, as I am no expert, just a user.

I have a Video system and I want to display permanently images that come from it when I run my application. Solution seems to be Direct Draw with 2 graphic board or a DUAL one. It is not really a problem, I suceed. But, there is a point that worry me. It is obvious that when my application is running on one monitor we will display video image and on the other normal interface and I'd like seeing mouse only on the normal inteface. But if we attach all the graphical boards to the desktop the mouse is moving on the 2 screen, I am afraid that is too confusing for customer. I'd like then use one board attach on the desktop (we need at least one anyway) and the other is sleeping, excepted when my application is running then it will display video. In term of programing that means we need to call Direct draw with the good board device. the function DirectDrawEnumerateEx is all what we need. It works well if all the board are attached to the desktop (that is to say we see all the board device) but any of the boards are not attached then I don't succeed in seeing them. However there is a flag DDENUM_DETACHEDSECONDARYDEVICES that seems to be specially provided for that use but it do not return anything about the detached devices. Is anyone can help?

i wan to output images which are coded basically in arrays of 1(presence of a bit)and 0(absence of a bit) to my SDI view, is there any samples around? not sure if it is something like cellular automata method...i am a beginner so need help in coding arrays and how to output in colour oso, for instance, i have a square which is an array of ones... how to show in on the SDI view and where should i code it coz i need to take in parameters from other dialogs. thanx

I created a modeless dialog with an accelerator table, but for some reason PreTranslateMessage is not called, so my accelerator keys are not translated to messages. Anyone knows why PreTranslateMessage is not called, or how to solve this problem?
|
|

|

Call PreTranslateMessage yourself; it's virtual.
Something like this:
BOOL CMyModelessDlg::PreTranslateMessage(MSG* pMsg)
{
if (!(m_hAccel && ::TranslateAccelerator(AfxGetApp()->m_pMainWnd->m_hWnd, m_hAccel, pMsg)))
return CDiaog::PreTranslateMessage(pMsg);
else
return TRUE;
}

I have something like you proposed:
<br />
BOOL CCentaurusDlg::PreTranslateMessage(MSG* pMsg) <br />
{<br />
BOOL handled = FALSE;<br />
<br />
if (pMsg->message == WM_KEYDOWN)<br />
{<br />
if (::TranslateAccelerator(m_hWnd, m_accelerators, pMsg) != 0)<br />
{<br />
handled = TRUE;<br />
}<br />
}<br />
<br />
if (!handled)<br />
{<br />
handled = CDialog::PreTranslateMessage(pMsg);<br />
}<br />
<br />
return handled;<br />
}<br />
But my PreTranslateMessage method is not called by the MFC framework. So where should I call PreTranslateMessage?

I feel my computer is playing a cat and mouse game with me, and I am the one losing. Here's why!
I can enter a bunch of strings and it can read one and ignore the rest, (meaning, it'll only give me the first one that it read), or it can read ALL, but give me NOTHING (meaning, it'll hang in the loop)!! Here's the code.
string str;
vector<string> vStr;
do
{
cin>> str;
vStr.push_back(str);
cout<<"\n Size: " <<vStr.size();
} while(str.end()!="\r");
======================
vector<string>::iterator iterB = vStr.begin(), iterE = vStr.end();
for(; iterB!=iterE; ++iterB)
cout<< *iterB <<" ";
======================
cout<<"\n" <<endl;The condition shown in the 'while' statement, will show the vector growing as strings are entered, but WILL NOT exit the 'do/while' loop.
However, if I were to change the condition in the 'while' statement to:
while(str.end()=="\r"); It'll exit the loop, but will ONLY give me the first string it read.
Ideally, I would like for it to read all the strings entered, and report all that it accumulated in the vector.
Thanks for any help.

I'm a little confused as to what you want your end condition to be... cin >> str reads in tokens delimited by whitespace (including \r and \n), and throws away the whitespace.
If you want to read an entire line of text at once, then look at cin.getline().

Try the following
#include <iostream>
#include <string>
#include <sstream>
#include <vector>
using namespace std;
int main()
{
string line;
getline(cin,line);
istringstream istrstr(line);
vector<string> vStr;
for(;;)
{
string str;
if(!(istrstr>>str))break;
vStr.push_back(str);
cout<<"\n "<<str;
cout<<"\n Size: " <<vStr.size();
}
return 0;
}

Thanks for replying.
I did review several options to my situation which included the use of 'istringstream'. At first 'istringstream' looked very promising, but after studying it some more, it didn't quite offer me what I was looking for (viz., an option that didn't limit the number of strings I might be receiving at any time).
'istringstream' is ideal for formatted string input and for a set number of strings. IOW, in your input stream syntax, you would have to show the amount of strings you are going to be receiving and their types (if other types are going to be part of the input other than just 'string').
Because the number of strings I would be receiving varies, I had to choose something that didn't restrict me to a fix amount, which told me that a loop would have to be the main mechanism.
I will look at your example, and again review what 'istringstream' can do for me.
Thank you for replying. I appreciate it.

I think I understand your problem. Have you tried checking for str.empty before pushing to the vector, and exiting the loop if the string is actually empty? I've not tried it myself, but I guess it might work.

Yes, I did try:
while(str.empty()); and got nowhere with it (meaning, it would not exit the loop). I also tried the opposite, 'while(!str.empty());' and it exited the loop but with only the first string. (IOW, the computer and I playing the old cat and mouse game.)
Thanks for replying.

I did not explain myself clearly enough. I mean:
for(;;)
{
cin>>str;
if(str.empty())break;
vStr.push_back(str);
cout<<"\n Size: " <<vStr.size();
}

Thanks for replying.
I didn't exactly try your last suggestion (according to the way you coded it), but I did try using the 'break' syntax, and it certainly did take me out of the loop. But guess what, the vector only had the first string entered in it!!
Believe me, before I posted this problem on CP, I tried a lot of ways, but always with one of the two standard results: either I end up with just the first entry, or I couldn't exit the loop.

As I understand it, end() will point just beyond the end of the sequence. Maybe that is your intent, but I'm not sure. Anyway, what condition do you want to terminate the do/while loop? Maybe something like:
do
{
...
} while (str[0] != '\r');

Thanks for replying.
Your sample gave the same result as:
while(str.end()!="\r"); which is, "receiving any number of strings and growing the vector, but unable to exit the loop."
The intent is to receive as many strings as inputted, and exit when finished.
The exiting part is the whole problem, because if I were to just enter one string, I can exit with:
while(str.end()=="\r"); I've tried a number of things while inside the loop (e.g. conducting certain discrete test and setting boolean values to signal to the loop that I'm ready to exit), and the best I could have ended up with came down to one of the two options I presented in my original posting.

From what I've seen, cin does not "return" until a non-whitespace character has been entered. This leads to something like:
string str;
vector<string> vStr;
do
{
cin >> str;
vStr.push_back(str);
cout << "\n Size: " << vStr.size();
} while (str != "9");
which is one step away from cheesy!

Cheesy or not, at this point I'll take whatever works.
Something else I tried, included inserting a delimiter at the end of the last string inputted, to signal that I wanted to exit the loop (how much cheesier than that can you get, I don't know), but that didn't work either.
Am I desperate? Not quite, but am getting there.

i've got a piece of code last week. When i wanted to compile it, the compiler couldn't recognise the symbols 'SEC_WINNT_AUTH_IDENTITY_EXW' and 'SEC_WINNT_AUTH_IDENTITY_VERSION' and 'FreeCredentialsHandle'
i've downloaded the latest Platform SDK (today). and put the include Path into the Directories for VC6.0 .. i am using Win2k.
Any ideas ?

Hi All,
I am trying to save the clipboard content as a bmp file. I tried like this:
<br />
HANDLE hBmp;<br />
OpenClipboard();<br />
hBmp = GetClipboardData(CF_DIB); <br />
if(hBmp)<br />
{<br />
if (WriteDIB("c:\\TEST.BMP",GetClipboardData(CF_DIB)) == TRUE)<br />
{<br />
MessageBox("Success","BMP Written",NULL); <br />
}<br />
else<br />
{<br />
MessageBox("Failed","BMP Write",NULL);<br />
}<br />
EmptyClipboard ();<br />
}<br />
else<br />
{<br />
printerror(GetLastError());<br />
}<br />
CloseClipboard(); <br />
<br />
<br />
void printerror(long err)<br />
{<br />
LPVOID lpMsgBuf;<br />
FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER|FORM<br />
AT_MESSAGE_FROM_SYSTEM|FORMAT_MESSAGE_IGNORE_INSER<br />
TS,NULL,err,MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),(LPTSTR)&lpMsgBuf,30,NULL);<br />
MessageBox( NULL, (LPCTSTR)lpMsgBuf, "Error", MB_OK | MB_ICONINFORMATION ); <br />
}<br />
I am getting NULL in hBmp. So if condition fails. I tried to get the error code. But error message says "Function completed successfully". Can anyone help me where i went wrong??
Thanks in advance,
Thoppae.
