When I made any editing changes to my ado project, randonly it bombs with the foll.errors. There is no going back with "undo". Then I have to make a brand new project, but that gets "corrupted" as well in a matter of a few edits. Has any one seen this? I could just be adding a messagebox!!
Thanks,

I get this periodically with some of my projects. It seems to be a bug in the VC compiler where it somehow gets upset with the input stream. Usually I can get past it by doing a rebuild all.

I had been exploring this class merrily when these errors starting happening. So I abandoned my strategy and started doing ADO from scratch. Now that REbuild All has dealt with the problem, I am almost afraid of trusting it, because if it doesnt go away next time with Rebuild All, I'll have to take up raw ADO and I have just enough time to go the one way - the class or raw ADO. Do you think rebuild all is trustworthy?
Thanks,

Hey,
I've just started trying to program with mySQL (first time programming for a database) and I'm encountering some problems. I'm using Visual C++ v6 and mySQL++ v1.7.1 and when I try to compile any program the compiler is coming up with hundreds of errors all of which reside in the mySQL++ source files. I find it hard to believe that there are actually errors in the source files and I can't seem to relsove this problem, if anyone had any ideas or solutions it would be much appreciated.
Thanks in advance.

 How can I access a database (in access2000) over internet connection.
I want to have an app that would upload a picture with a description to that database remotely.
Thanks

Hello, the codegurus around the world.;)
You can use Socket program or ASP.
1) Socket case.
Create your own client and server by WinSock or CAsyncSocket class.
Add the code with the database in Server side application.
Server can access the database.
2) ASP case.
Write some simple ASP code to Access database in your local web server or
remote web server.
Write the client application with WinSock, CAsynSocket, or WinInet
to post HTTP command.
(WinInet is the easiet way.)
Last, I actually did these.
Please, don't send me your email about your questions directly.
Have a nice day!

ok, so asp will have an access to database...but it cann't upload pictures with descriptions.
and what will the client app do?

Does anyone happen to have an equation to calculate the distance between two lat and long points? My calculation is apparently wrong and with all the sines and cosines and the fact I've been up all night I'm a little confused. That and I specialize in databases and not geography. Also, are latitudes in the NW hemisphere supposed to be positive?

Hi there,
I have a strange problem in my program about releasing allocated DC memory !!!
struct Container
{
CBitmap* bmp_ShapeMask;
CBitmap* bmp_DegreeMask;
CDC* dc_Shape;
CDC* dc_Degree;
.
.
.
Container()
{
bmp_ShapeMask = new CBitmap;
bmp_DegreeMask = new CBitmap;
dc_Shape = new CDC;
dc_Degree = new CDC;
}
};
ok, then i loaded images and also i allocated memory for dc_Shape and dc_Degree:
m_Con.dc_Shape->CreateCompatibleDC(.........);
m_Con.dc_Degree->CreateCompatibleDC(.........);
m_Con.bmp_ShapeMask.LoadBitmap(......);
m_Con.bmp_DegreeMask.LoadBitmap(......);
and in one of my program part, i want to release all of the allocated memories ...
i wrote:
m_Con.dc_Shape->DeleteDC();
m_Con.dc_Degree->DeleteDC();
m_Con.bmp_ShapeMask.DeleteObject();
m_Con.bmp_DegreeMask.DeleteObject();
delete m_Con.dc_Shape;
delete m_Con.dc_Degree;
delete m_Con.bmp_ShapeMask;
delete m_Con.bmp_DegreeMask;
But when i got report from system memory, i saw that my program doesn't release the memory
What's the problem ???????
Please help me !!!!!

You may be leaking other resources like when you do a SelectObject on the dc you must re-select the old object when you are finished.
CBitmap *pOldBitmap = dc.SelectObject(m_Con.bmp_ShapeMask);
dc.SelectObject(pOldBitmap);

He deletes DC's before bitmaps, so bitmaps are released. Besides, he gets the leak reports from C runtime, not from GDI. CBitmap can be deleted from heap even if underlying GDI object is selected in some device context.

Please bracket your code within <pre> and </pre> tags. Also remember that your variable and function names mean little to a non German speaking audience.

Your code is a little long ... Could you extract essence of this (I mean isolate the bug)... Is your compilation OK (no error, no warning)?
if not, what's your error/warning report?

Hi,
Is there a CTextFile class in Visual C++ that allows us to read text files line by line (ReadLine and WriteLine) ? or we have to use the CFile class, read then parse the buffer for CR and LF ?
Any method to read/write text files ?
Thanks

CStdioFile has ReadString and WriteString methods.

You may try with TerminateThread, but it's quite dangerous. Check the MSDN for list of thing which may go wrong.

To "force" a thread to end, you have to use TerminateProcess, and as has been mentioned, it can be dangerous.
However, you can be more diplomatic than that. You could send your thread a Windows message, or set a shared variable (flag), to let the thread know it should quit. You will need to code up the thread so that it periodically checks to see if it should quit or not.
Even if you win the rat race, you're still a rat.
