we have developed a multithreaded win32 application using vc 6.0.Try catch exceptions are handled.But still when the exceptions are thrown, the threads get frozen except the primary thread.
Can anyone give suggestions?

Don't use exception handling, re-code in a defencive manor, checking things rather than waiting for things to explode.

> Don't use exception handling
This may be impossible - if he's using some library reporting error conditions using exceptions.

Hi all, i use the same code in my CView derived class to draw icons to both the screen and the printer. I use CDC::DrawIcon to do the drawing. The icons show up properly on the screen, and on print previews. They just don't actually print. I've also tried using ::DrawIconEx, but to no avail.
Any suggestions? Thanks in advance!

There are tow hosts in a local network. One has database source files ( mdb files ) and the other accesses them by using ODBC DSN. sometimes it happens that a database source file breaks down and
message dialog says to repair the databse file immediately.
Why does the database file break down ????
Somebody help me.
Thanks in advance.

thank you for your concern.
Let's suppose that two customers visited my shop.
They look around my shop and purchase goods they need.
each of them goes for accounts , one to left and the other to right.
each of the two accounters processes his transaction ; updates mileage of the customer,
updates the left of each item, records details of sales, and so on.
in this situation, one host, client , could access the same database file to which server accesses at the same time.
that's all. please, help me.
i'm not apt at english.

You need to use transactions to ensure the integrity of the database. If you are using MFC database classes, see CDatabase::BeginTrans(), CDatabase::CommitTrans() and CDatabase::Rollback(). Also, check that the relationships between the tables are correctly (and completely) defined in Access.

Hallo everyone,
I am a student and have to make a little program in Visual C++ that launches an “event” on a certain date and time.
A good example are the programs who save birthdays and launches them on a predefined date and hour or the programs who launches a certain program on a certain date and time. A sort of schedular.
Is there someone who has the source code for such a program, so I have a little example.
I would be very gratefull !

Use GetSystemTime to know the time, use OnTimer to check at a regular interval and use ShellExecute to run your other program.

I have searched and searched, but I cannot find anything about implimenting jscript or vbscript into C++.

Did not exactly understand the question.
Do you just want to call VBScript or JScript code from external files to be run for VC++ code or
Do you want to pass parameters and get return values?

Why not use a server-side scriptlet? This will enable your JavaScript or
VBScript to the accessed exactly like a COM object
Search for "Server Scriptlets" in MSDN.
There is an article by Dino Esposito that deals with it.

Hi all,
The service I'm writing (i.e., a console app) needs to load resources from its exe file- is this possible? How do I get the HINSTANCE of the module?
Cheers,
NickB

Use the line:
HINSTANCE hInstance = ::GetModuleHandle(NULL);

I need to have a loop of code that will be executed for between 1/20 of a second and 1/4 of a second (I'm not sure of the exact time yet)....thus I need to be able to time miliseconds....any ideas?
|
|
|
|
|
Use the GetLocalTime before and after the loop
The difference in the times will give you the difference in milliseconds.
Another way that I use to increase the accuracy is to run the same exact loop 1000 times in a loop. So the time taken can be calculated to the accuracy of microseconds.
I do not know, whether this is the answer that you are looking for, but I hope this helps you.

timeGetTime returns a time in milliseconds.

while (condition)
{
//your code
Delay(time_in_mili);
