Why you want to use adirectx versionthats at least 5 years old I have no idea. but...
this is an example
http://www.codeproject.com/directx/basicdd.asp[^]
By the way you can use the MFC libraries in a win32 app. Its much easier to show a bitmap and init'ing directx.

Cool, thanks a lot.
(And regarding why I am using an old version of direct X and why I am not using MFC:
After I learned C++, I was getting pretty bored of console apps, and wanted to learn how to windows apps. I tried from various tutorials for a while, but as I am fairly new to this, I was unable to make any progress.
Then I found an old book, called "Tricks of the Windows Game Programming Gurus", by Andre LaMothe. Its outdated, sure, but the gradient was perfect for me, and it was all I had at hand.)

its a good start.

If I use the default "Save", "Open", or "Save As" in the Menu of an Single Document Interface, my program is unable to open files internally. The files I open internally and those I use the above menu items on are not the same, and are not related.
PLEASE HELP! How to overcome this problem??

Use full path names when specifying your files. The default file dialogs change the current directory.

The files I use internally are in directories that are in the same location as the program. IF someone moves the whole thing, how can I get the file path? I used "Directory1\file.txt" before, but how to get the whole path?
Thank you very much. I will try it manually to see if it will work. Thanks!

You can use GetModuleFileName() to get the path to the .exe. You can use that path to build your file paths.

Dear Sir,
Thank you VERY MUCH! It worked, and my program seems to be running ok. I really appreciate the help. If you're ever in the Philly area, let me know. I owe you a drink!

I'm working on a program that reads a small text file (from AppPath) every x seconds, and is always running on the computer. Since most computers are always on, should I keep that x value as low as possible to reduce wear on the hard drive (and maximize laptop battery life), or is that not really a problem? I currently have x set at 5 seconds, and could go as long as 60 seconds.

If you are waiting for the file to change some how you may be better off using this[^] approach.

Doh, can't believe I didn't think of that . Thanks!
I actually decide to use FindFirstChangeNotification, because it supports 98/ME.

People that use power management (eg laptops) will not be happy with that method, because the constant disk access will prevent the computer from going into power-saving mode (stand-by/hibernate).

My problem is that I have to read the content of a web page which is dynamic (written in PHP), and the content is always different. I read the content using the following code :
<br />
void CHS_VCDlg::Onread() <br />
{<br />
CString URL = "http://www.eed.usv.ro/~pentiuc/hs2005/index.php";<br />
CInternetSession session;<br />
m_Result += "Trying " + URL + "\r\n";<br />
UpdateData(FALSE);<br />
CInternetFile* file = NULL;<br />
try<br />
{<br />
file = (CInternetFile*) session.OpenURL(URL);<br />
}<br />
catch (CInternetException* pEx)<br />
{<br />
file = NULL;<br />
pEx->Delete();<br />
}<br />
if (file)<br />
{<br />
m_Result += "Connection established. \r\n";<br />
CString line;<br />
for (int i=0; i < 20 && file->ReadString(line); i++)<br />
{<br />
m_Result += line + "\r\n";<br />
}<br />
file->Close();<br />
delete file;<br />
}<br />
else<br />
{<br />
m_Result += "No server found there. \r\n";<br />
}<br />
m_Result += "------------------------\r\n";<br />
UpdateData(FALSE);<br />
}<br />
It works well, but the problem is that I have to clear the cache and the cookies all the time from Internet Explorer.
I want to know if there a way to clear the cache and the cookies by code in order to read the new content of the page every time I call this function??

I tried ti use DeleteUrlCacheEntry() and even found a more complete function:

I tried to use this function but I get the following errors:

I am trying clear a Cstring variable null. I tried NULL, didnt work.
I tried '\0' , worked but i can't append anything to the cstring.
I just need to make cstring variable blank(or clear it) and when user presses the number buttons, they are appended to the cstring variable.
Thanks in advance.

Two more cstring question-
How do I determine the length?
How do I compare individual elements of a cstring?
I am trying to find out the number of digits entered after the decimal point in a floating point number like 2.33

did you watch this ????
CString::length() -> returns the length of the string
if you like to compare 2 elements, you can use either operator[] () or GetAt() ...

I am trying to get the Text Object Model interfaces to work, but it seems that some of the functions simply do not work right.
According to the docs the ITextRange interface has a method called ITextRange::GetPoint() which, supposedly, will return the x,y coordinates of the range. You can specify a flag that is made of a series of bit flags that tell the function what the coords are for (the start or end) and whether you want the top, bottom, left/right, or baseline, center.
However no matter what you send in, the fucntion always returns E_FAIL as a HRESULT value. Does anyone have any experience using these API's? I'd love to be able to get this to work.
