Re: How to programmatically disable network card

Thanks for the thought. I have indeed been experimenting with this with some success. However, it's also a good thing to turn off sources of hardware interrupts that I would just as soon avoid. I deal with the disk I/O problem by using a gigabyte of RAM, locking pages in memory, and avoiding any file I/O until the acquisition is complete.

Since I only need this priority level for a small portion of my application's running time, I use SetPriorityClass() rather than CreateProcess().

I am trying to capture 5000 frames per second from a high-speed camera, so I am trying to avoid even an occasional millisecond of latency.

I would really like to work with an RTOS, such as QNX, but the frame grabber board I must use only has drivers for Windows.

I did a quick google search and came up with a few things that might help. Someone mentioned that there's a sample in the Windows DDK, under NTDDK\src\general\setup\Enable. Whether that has disable code or not, I'm not sure Smile | :)

More interestingly, there's an external program named DevCon that might do the trick, and apparently Microsoft gives out the source code in their latest XP DDK:

Thanks a million! Those pointers help me with exactly what I need. For the moment, calling DevCon from my application should do just what I need. Sometime later, I can see about incorporating the DDK code into my application's core.

Thanks so much for pointing me an answer.

What is the correct way to update the FormView(EditBoxes)on the fly from the Document after the OnInitialUpdate? I am currently using a pointer to the View object, this works but seems to me that it is by-passing the rules of encapulation.

Hi there !!

I am currently working on my term project in VC++ using MFC. I want to implement MSN Messenger type System tray alert messages (which appears when a user signs in or a new email is recieved ) in MFC. If anyone could tell me how to implement it , which classes to use or could tell me any references or any example, I would be obliged. Big Grin | :-D

My question has two parts.
In order to split my project into smaller parts I had to create an mfc extension dll. According to msdn, extension dlls can only use mfc as shared dll although VC 6.0 allows me to link with static mfc library too.(?? I am confused here) Also using extension dll forces me to link my client.exe with shared mfc dll too. Can I avoid all of these and link all extension dlls,client.exe with static library. is there a trick for this ?
Second question is if I use shared mfc dlls do I have to distribute them with my installation or do they come with windows setup by default. The dlls are mfc42.dll and msvcrt.dll
I hope my questions are understandable because I am confused because of this static , dynamic mfc stuff.
Thank you

MFC Extension DLL is an add-on for MFC42.dll. It needs it by design.

Thanks for the information. I was trying a few ways to
do it and it's working!! Just curious, is there anyway I could replace the whole line of the title bar. I mean I could replace the Untitled part, but not able to get rid of

how to recognize word from sentence?

you will also have to use punctuation marks such as '.',',',';' etc. Hyphens are also wierd as they can indicate a joining of words or that a word has been split to allow it to wrap at the end of a line (not end of sentence), this normally happens after the 3rd charcter.

true - but I remember a 3 letter rule as well that you do not break the word if the first part is less than 3 letters but just start it on the next line.

Somebody is not doing their homework. How do you expect to learn how to program if you dont want to do the work? I sugest switching courses. Youll get no help here.

Heres some assistance though. Define "what" a word is. Is is a series of alpha characters followed by a space or possibly a form of punctuation? . , ; ' : -
or is your programs definition of a word slighly simpler?

can a word have numerical characters in it? is l33t a word?

parsing word from sentence?

I think you should be misunderstanding, or else it is my fault. i suppose to post my coding and lets you all expertise and checking the error for me. However, the system now is workable for space. one more question is if i would like to get some particular word, lets say 3rd word from the sentence. then what should i add inside?

the following is the coding:

#include <iostream>

using std::cout;
using std::endl;
using std::cin;

#include <cstring>

int main()
{
char string[256];
char *tokenPtr;
cout << "Enter sentence\n";
cin.getline(string,sizeof(string),'\n');

cout << "The string to be tokenized is:\n" << string
<< "\n\nThe tokens are:\n";

tokenPtr = strtok( string, " " );

while ( tokenPtr != NULL ) {
cout << tokenPtr << '\n';
tokenPtr = strtok( NULL, " " );
}

return 0;
}

scrollbars in a richedit

ns17-Sep-02 4:36

17-Sep-02 4:36

I was positioning my richedit so that it hugged the bottom edge of my UI at all times using (in OnSize):

m_editright1.MoveWindow(cx - 200, 390 - VScrollDistance, 200, <code>cy-350+ VScrollDistance</code>);

This works well, but the edge hugged is the visible bottom edge, not the region hidden by the scrollbars of my MFC MDI app. (Strange fact: If I scroll down completely and resize it does elongate (beyond?) to the real bottom edge). SO in order to make sure I definitely get the bottom hugging behavior (with or without scrolling and resizing) I made the box superlong:

cy+ VScrollDistance.
The problem is that the vertical scrollbars never develop for the control even if I shrink my UI to be less tall and the text gets obscured. If it truly hugged the bottom at all times, I feel the scrollbars would develop. Any ideas on how I can get it to align itself along the TRUE bottom edge of the UI and not just the visible region right from the start.( I do this positioning in the OnSize event which seems to run after OnInitialUpdate, so any positioning I do in the latter will be overridden)?

Thanks,
ns

I have been able to automate Word using my application. I have been able to write three lines of text into it.

Now how should I create tables and format text in it.

It looks like you have a working technique to communicate with the Word app. If you are asking about the specific commands to issue to word to create the table and do the formatting, I suggest you let the Word program tell you.

Turn on the macro recorder, perform the operations of interest (create table). Then turn off the recorder and read the macro. It will contain the commands you need to implement. The implementation is just like the stuff you already have coded.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
