If the machine has static IP and
If is direct connected to internet just connet to it by IP.
If you can connect to it that means is on the net.
If the computer is behind a firewall/ home-router or proxy
configure the 'gate' to allows incoming connections for that particular
machine . Then you connect to the router/firewall.
If the compuuter does not have a static IP
you have somehow to write a service that reads the machine IP
and ecah time when it change to write you a mail on a yahoo/hotmail
acount sending you the new IP (I have this service I wrote 4-5 years ago)
...or goto freedns.com
and get a name from there and a daemon that runs on your pc and each time
whern you get another IP it notify the freee.dns. Then you can use the
dns name you got from freedns.com.
Hope It Helps.

I have a spinbottonctrl on my dailog with editbox and Slider that are linked to each other. As I clicked on SpinBottonCtrol and it gets to a certain point all the sudden no more increment. What happend? I explicitly set the range from 0 to 3000. However, when it get somewhere around 500 it stops why why why???
Actually I want it to increment one by one everytime you click even you keep clicking on it for a while( by defalt after clicking a while, it increments by 5 and afterthat 10 as you know).
pNMUpDown -> iDelta = 1;
Was it a problem?
If someone with the answer to this question let me know.
Thanks in advance
Shinya

Hello All. i'm trying to get the file properties.
like all the information appear on file properties page ( select file name, right click, properties)
i know i can get the file size, created date, access time, modified time, attributes..
I used following code to get an extral information like titl, author, summary, comments, etc.
<br />
HRESULT hr = S_OK;<br />
IStorage* pStg = NULL;<br />
hr = ::StgOpenStorageEx(wcFilename, STGM_READWRITE | STGM_TRANSACTED, STGFMT_DOCFILE, 0, NULL, NULL, IID_IStorage, (void**)&pStg);<br />
if(FAILED(hr))<br />
{<br />
hr = ::StgOpenStorageEx(wcFilename, STGM_READWRITE | STGM_TRANSACTED, STGFMT_FILE, 0, NULL, NULL, IID_IStorage, (void**)&pStg);<br />
if(FAILED (hr))<br />
return false;<br />
}<br />
<br />
IPropertySetStorage* pPropSet = NULL;<br />
hr = pStg->QueryInterface(IID_IPropertySetStorage, (void**)&pPropSet);
but it only work for MS office files. it doesn't give any information for other regular file like, pdf, tiff, jpeg files.
How can i get the information properties of regular file (eg. pdf, tiff, html, jpg,giff,etc..)
Thank you

I'm adding to this editor (http://marius.homeunix.org:8000)
Sphere template brush.
The sphere of course has more polygons than any other primitive there.
So If I create a sphere with 32 bands and 32 sections I get 1K polygons. Sphere is a solid so all its facea are facing out, so the BSP will be a straight line having on left 1024 nodes and each of it
on right s empty node containing one polygon.

I get Stack Overflow. I tried to reduce the stack storage
to minimum So I reduced it from 1040 bytes to 600 bytes.
The number of recurvie calls has increased a bit but I still get
the stack overflow.
Have you any ideea of unroling the BSP compilatin ptrocess.
Thx

Just an idea that I've used experiencing the same kind of problem in my product(http://members.cox.net/igor.tebelev/astlview2.htm).
I don't know possible depth of your recursion, but for my case, where I was traversing just 3 edges of triangular plane in order to find not connected triangles and extract different solids from multiple assembly: i had to implement alot in optimization in stack size reduction:
1. minimize stack variable usage (600bytes is alot -- I don't know specifics of your code, but why not allocate stack dynaArrays in your case on the heap?);
2. minimize call arguments size (maybe it's impossible in your case, but you may consider instead of having 2 args passed to recursive function, have just 1 pointer to the struct containing those 2 values);
3. try to replace your local stack vars with possible static equivalents if not used from different thread ( for example in your case, why can't CMiniNode* fn can't be static? or Poly frontPoly; Poly backPoly?);
4. declaring your recursive function static (if possible), so this will not occupy place on the stack...
5. it all depends on the logic, but you may look into some kind of optimization that will protect from possible reentrance and attempt to analyze something that could of been done before (not sure you have this case)...
After doing all of the above in my case: I was still getting stack overflow cases. So, what eventually I've done: reinvested some time in changing algorithm, so I limited my recursion by some constant depth of the recursion, and as soon as it was getting reached I was interrupting it and restarting again from the top, however I was saving important data in one huge array, so my next recursive call doesn't process entities already processed and was using that arrays data however. Not sure it's possible in your case, but only you can come up with something like that.
I've managed to resolve that problem back then. However, there maybe another approach that I've tried more advanced approach back then and it worked just fine: It requires some adavanced ASM skills, but basically it was like that as soon as constant depth of the recursion was reached: you allocate some memory on the heap, change stack pointer and etc...

Thank you Igor.
I'll dig into it this weekend.
Thank you again.
P.S. Cool 'StlView' you have.;)

BTW: I forgot to mention another alternative.
Imagine the following solution, that I've also tried at some point:
Instead of playing with ASM in stack switching: you may reuse treads to perform your deep stack calculations. So, what you do again have some stack call counter and as soon as that variable reaches some threshold, your code spawns separate thread, sets calling args on that thread and runs it again with the call to the recursive function, while thread creator waits till spwaned thread finishes. What happens here is: system creates thread that will either inherit your original stack size or you will specify stack size of that thread. The drawback maybe overhead in thread creation, however that should be tested...

Has anyone done any street address parsing? I'm working on a project that pulls an address of which I need the street address, city, state and zip. Pretty simple working backwards until I hit the city. Then it I hit a snag if the city is 2 words and the user doesn't use a comma.
Any suggestions??

I did this exact same thing. I worked backwards from the State/ZIP. You can identify the State because there is a limited set of them for example last word is "York", then scan for "New" in the second to last. The rest is the city. You can grab a list of states from source html for option boxes on the internet.

we dont all live in America!!!!!!!!!!
Id say you should include an Austalian, an English, an American and at least one non english speaking country in your test data.
Perhaps you could define a template for each style of address (post code format etc) and then select the template based on the country (there are a limited set of countries) and they parse the address using the information in the template.

Hi I posted a message yesterday as well but i dont still get it what should i do....
it is very simple.. but i have never worked with forms and i only know about consule project. iostream!!
I am trying to build a form and run a specific application with it. I am already made the project as a console project using fstream.
I want to get the name of the file from the user in a specific text Box and then open it as follows:
char fileName[];
ifstream infile;
infile.open(fileName);
However what i get from the textbox is String *f = textBox->Text;
How can i convert this to char[]?
I have already tried char fileName[]=f->ToCharArray(); but it seams there is a problem and i cant convert _wchar to char!!
how can I do this?
is there another way to open the file ?

Are you trying to get the string from editobx?
If you go with MFC..
CString str_FileName;
CEdit * pEditBox = ( CEdit * )GetDlgItem( ResourceIDForYourTextBox );
pEditBox -> GetWindowText( str_FileName );
I am not sure if this is the answer to your question.

Hi There,
I did a program in VC++ 6.0 for change Password(fields: username / password / new password / confirm new password ).
It is based in MFC (Dialog).
The program is running no problem.
The question is that i need to show a message (like TIP TOOL message) when user will enter with the new password and the CAPSLOCK KEY is actived it should shows a message like: "WARNING: YOUR CAPS LOCK KEY IS ON" it is like a TOOLTIP message, but the diference is that tooltip is based in mouse events and this is based if the CAPS LOCK is turned ON... but the message i want to say is like TOOL TIP message...
Please, can someone help me???
About CAPSLOCK KEY verification it is okay, i am having problems just in the question of SHOW THE MESSAGE!
Thank you all in advance...
My hairs (that are falling for cause of it) will thank you 
Fernando
ps: english is not my first language.
Then I must do the simple thing:
|
|
|
|
|
There are two ways of doing this:
OnTextBoxChange (message handler)
OnKeyDown
Use GetKeyState ... look it up on the MSDN find the corresponding VK_ for the caps lock.
example:
if (GetKeyState(VK_LCONTROL) & 0xfffe)>0)
Use a MessageBox or if you want to go the extra mile there are articles here about the MSN popup dialog boxes (search for it ) and XP bubble windows.

I have some video files in different formats - avi, divx, wmv, asf, mpeg, ...
I can open and play them using DirectShow.
But I have 2 problems :
1. I don't know how to detect the video format.
I know DirectShow will do this for me, but I need to notify user,
wheter is it divx,xvid,mpeg 4, or some other format.
Detecting by file extension is not reliable , and not possible, since more formats are using .avi extension.
2. How to find out, whether video file contains audio ?
Like Windows media player grays out volume control when movie does
not contain the sound.
Thanks !

Have a look at http://www.jmcgowan.com/avi.html[^], a very informative site he has a freeware prog called vidtrace, a cosole app, that decodes an AVI file for you http://www.jmcgowan.com/vidtrace.exe[^]
Runnning this may help you decode/understand the RIFF data
