How to read Windows User Name and the machine Host name in a VC application ?
|
|
|

The function NetWkstaUserGetInfo can be called to get the User Name.
The function NetWkstaGetInfo can be called to get the computer name.
There are security restrictions in place that could cause these calls to fail, though.

Many Thanks !
I´ve done it this way:
DWORD dwLength = MAX_COMPUTERNAME_LENGTH + 1;
CString csComputerName;
GetComputerName( csComputerName.GetBuffer( 0), &dwLength);

Hello,
I have a problem in using threads.
There is a main thread, when a button is clicked a dll has to start executing.
This process takes some time, to a user it appears as if the system has crashed.
So I use thread to display a progress bar during the execution of the dll.
The problem is that, the progress bar does not get updated during the execution of the dll, the dll seems to block the thread.
(The dll is written by someone else so I have no access to the source code,
I know only the inputs and the expected output.)
The thread(worker) is implemented as a global function (UINT....)it also has
the highest priority.
Could anyone please help me.
Nami.

1. Simplify - you have mentioned 3 threads (main, progress box, worker) - simplify to two threads (main [run progress box here], worker)
2. If your worker has higher priority than the main thread, the main thread will not run unless the worker thread yields in some way - a WaitFor... or Sleep statement, etc. You will want the two threads to have the same base priority and then the main thread will have a slightly higher priority because it will have the focus but the worker thread will still be serviced.

Hello,
Thanks for your reply.
There are 2 threads in the application.
The first is the main thread and the second is a worker thread
which is used to draw the progress bar on the screen.
I have used
do
{
//draw the progress bar
}
while (::WaitForSingleObject(g_eKillTimerThreadProc.m_hObject, 0) != WAIT_OBJECT_0);
The main thread is used for the dll execution.
The problem is that the progress bar starts and stops in middle and reaches 100% only after the dll has been executed.
Thanks for your time.
Nami

A while ago I posted a question about an application that I have written with a MSFlexgrid control. When I copy the app to my target machine, I find it wont run, even when I copy the dll files that it asks for over. What is the soloution? I did ask this before, but cant find the thread, so sorry for asking again.
I believe the solution did involve using Dependancy Walker - do I need to just copy the list of dll files that Dependancy Walker shows?
Thanks for any help - sorry for asking again!

Use regsvr32.exe to register the flex grid control.

the CLR (Common Language Runtime) means that code can be written in one language and called in another.
As far as i know, this is limited to being able to interchange DLL functions / classes.

There are many IPC (inter process communication) options including (but not limited to) COM, RPC, shared memory. etc. I'd go for the COM approach.

Hi !!
I have DLL in my application.It is working properly in Debug mode but not in Release mode.I found the problem with CString and I had clear all those CString problems.But when i directly ru the application in release mode it shows the Application Error.I click cancel to Debug (i release mode only), it gives "Unhandled Exception".When i debugging the application (in Releasemode), i didn't get any application errors.

Check for uninitialized variables, especially pointers.
In debug mode, they get initialized to zero/NULL (by the debug memory handlers).
In Release, they doesn't get initialized, unless you do it yourself.

In addition to others I would recommend you to enter in the
Release <br />
<br /> directory of your project, delete all files inside and then Rebuild your
project.

Check that you have used an absolute filepath to find the DLL
|

Here is my "Debug works, Release crashes" checklist:
-check for uninitialized variables, esp pointers.
-check build settings that only release mode libraries used
-look for ASSERT's with non-const expressions - use VERIFY here instead
-in MFC, look for mismatched message handlers, esp for OCX's.

Hi all
Please tell me how to temrinate an EXE which was created from the VC++ application using "ShellExecute".
To use TerminateProcess(), we should pass the handle of the process. But i how can i obtain the handle when i use "ShellExecute"?
and also In CreateProcess() function i don't find any parameter for "passing the parameter to the application to be invoked".
Bye
