Let's say I have a file that is entirely strings but it's binary due to some nulls ('\0') in between the strings. So technically, it's not an ascii file (32 - 128), it's got some 0's in it. So using, cat, it would be cat -A thefile.txt to see that there are nulls in it. cat thefile.txt would just show the pure ascii text.
I can create an ifstream object and read it in line by line using either of the following:
#include (the proper include files, sorry I've omitted them here)
using namespace std;
string buffer;
ifstream if;
getline(if, buffer, '\n'); or getline(if, buffer);
or:
if >> buffer;
The above 3 different methods will ALL read an entire line from the file. I can easily
prove this by cout << "buffer = " << buffer; and it will display the line from the file,
including any nulls or whatever.
But now suppose, I want to use extraction (as in I want to tokenize the lines into parsed strings, right into string variables).
My problem is that stringstream does NOT behave in this manner unless you have a true mixture of binary globs of data. As soon as you stringstream extract into a string variable, it reverts right back to the behavior of the getline and grabs
the entire line.
Is there anyway I can use extraction and have it understand that I want ONE string
at a time? For example, by setting a delimiter?
I know I can set a delimiter in the getline function. It's just that I want to do it with the extraction operator (ie. modify stringstream and/or ifstream's extraction).
Or is there yet another class that I'm missing? I do not want to use boost in this project. And I do not want only Windows-specific classes - I want something generic.
If I really do have to "roll my own", then fine, I have to do that.
In my case, if I DO have to roll a new extraction or overload the behavior, it will need to be done for all types, not just strings - I would guess.
Thanks.

microsoft spy does not detect any message with an application
-hi, i have an application and if I use microsoft spy to see the messages to the window of an application, it doesn't detect anything.
I'm asking, how is it possible?neither the mouse or nothing...thank you. does Spy detect messages also if the application is written in Java?

Close [X] aplication issue
Hi!!
I have a MDI aplication that has MDI windows and top windows and unfortunately the document interface is not implemented. When I press the X button on the aplication (not on the child frame) I need to save all modified documents on MDI and on Top Windows, but before save the documents and close the window I need to get the name of the file that is on the view.
The problem is that I cant get acess the all views from the childframe. In OnClose on the MainFrame I made a while to acess all views and get the file name but it is not working. I have tried get the view form several messages like GetActiveView() GetWindow() and send message (WM_SETFOCUS) from all possible ways. (If I get the focus on the view I can get the filename.) nothing is working. What is Wrong?
I wrote on Onclose of the MainFrame:
Code:
---------
void CMainFrame::OnClose()
{
int Maximized(0);
CMDIChildWnd *CW(MDIGetActive(&Maximized)),*PrimCW(CW);
while(CW)
{
//--- none of these is working.... ----------------------------------------
CW->GetDesktopWindow()->SetFocus();
CW->GetDesktopWindow()->SendMessage(WM_SETFOCUS);
CW->GetWindow(WM_SETFOCUS);
///--------------------------------------------------------------------------
CW->SendMessage(WM_CLOSE); //--- Ok but I don´t get the file name.
MDINext();
CW = MDIGetActive(&Maximized);
if(CW == PrimCW) CW = NULL;
}
CMDIFrameWnd::OnClose();
}

Thank you

riched20 in 64 bit app

Thanks you

How to create a AutoHotkey like hotstring using C++?
I have figured out an effective way to create a hotkey using C++.
AutoHotkey example Alt+A to run a file.
Alt & a::
Run, C:\blah\blah\blah\abc.png
Return
C++ example Alt+A to run a file.
Code:
---------
while(true) {
if( GetKeyState(VK_MENU) & 0x8000 ) {
if( GetKeyState('A') & 0x8000 ) {
ShellExecute(NULL, "open", "C:\\blah\\blah\\blah\\abc.png", NULL, NULL, SW_SHOWNORMAL);
}}}
---------
I now want to understand how to create a hotstring using C++. For example how can I convert following AutoHotkey code into C++?
Code:
---------
::abc::
Run, C:\blah\blah\blah\abc.png
Return
---------
I don't know what logic the AutoHotkey developers used in creating the hotstring functionality but I think something like this might work.
Code:
---------
if( GetKeyState(VK_SPACE) & 0x8000 ) {
// press Shift+Left until space detected;
// press Shift+Right after space detected;
// press Control+C to send highlighted word clipboard;
// convert clipboard to string;
// add that string to a variable;
if(//the value of variable is abc) {
ShellExecute(NULL, "open", "C:\\blah\\blah\\blah\\abc.png", NULL, NULL, SW_SHOWNORMAL);
}
else {//send space}}
---------
The problem is I don't know how to implement this completely because while I can send keyboard events, I don't know how to detect highlighted characters and use them in if statements. plus, I don't know if this is the best way because it might make typing a simple space take too long. Someone please help.

CView to PDF
I have an MDI app, with view derived from CScrollView, where I draw text, lines, and images. Is there any chance to export this CMyView to PDF, without any virtual printer or some third part library ?
Of course that I have search on internet for solution, but I have found nothing ...
Can you guide me to solve this issue ?
Thank you.

Matlab
I have a Gui with a table in it.
When a press a button it should fill the able with the results from an array in the workspace!
BatteryDischargeCalc = assign(handles.uitable5,'data')
% set(handles.uitable10, 'Data', BatteryDischargeCalc);
These are the commands I have tried and have had no luck?
Any ideas?

Filling an array with random lines from a file
Hi
I currently have a program that reads the first 10 lines from a text file and adds them to a vector array, however how would you instead choose lets say 100 random lines from the text file and place those into the vector array.
Code:
---------
const char newLine = 10;
ifstream file("rockyou.txt");
vector arr;
for (int i = 0; i < 10; i++) {
string temp;
file >> temp;
arr.push_back(temp);
}
for (int i = 0; i < 10; i++) {
cout << arr[i] << endl;
}
}

Thanks for any help you can provide.

An error in my code - binary digit matrix implementation by using 2D vector
Hello
I'm doing a code in C++ which must execute a matrix in output contain binary digits, vertically.
the programming environment is visual studio and when I use void in front of my 2D vector, I have one error, unfortunately, and I cannot solve this error
when I use vectors which I commented in the following code without void function everything is okay and if I want to merge them into one vector like following with void function I will have an error in this line:
