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.

MSFlexgrid

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.

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.

Doubt in CreateProcess() and ShellExecute()

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

You can't. Use ShellExecuteEx or, much better, CreateProcess to retrieve the handle.

From MSDN:

BOOL CreateProcess(
  LPCTSTR lpApplicationName,
                         // pointer to name of executable module
  LPTSTR lpCommandLine,  // pointer to command line string
  LPSECURITY_ATTRIBUTES lpProcessAttributes,  // process security attributes
  LPSECURITY_ATTRIBUTES lpThreadAttributes,   // thread security attributes
  BOOL bInheritHandles,  // handle inheritance flag
  DWORD dwCreationFlags, // creation flags
  LPVOID lpEnvironment,  // pointer to new environment block
  LPCTSTR lpCurrentDirectory,   // pointer to current directory name
  LPSTARTUPINFO lpStartupInfo,  // pointer to STARTUPINFO
  LPPROCESS_INFORMATION lpProcessInformation  // pointer to PROCESS_INFORMATION
);

So what you are looking for is probably here lpCOmmandLine

I think you mean lpProcessInformation.hProcess.

Actually not, with this I was answering his second question "How to pass parameter to the invoked thing".

I agree I should have stated this more clearly.

PropertySheet tabs captions

gd' morning everyone (yup, i'm still wakin' up),

i have a problem in my wish to move every GUI Strings of my project[^] into the resource strings table.

i can easily construct the caption on the propertySheet dialog using this->SetTitle() in my propertySheet constructor.

my need comes when i try to initialize each PropertyPage's caption (which end up as a tab) using this->SetWindowText() within CMyPropertyPage::OnInitDialog(), the tabs remains empty...
when i debug, the CString is correctly loading the resource string from the string table, so i think that it is the call to SetWindowText which is not appropriate. moreover, the breakpoint in oninitdialog is reached only when i navigate through the tabs (not at the first diplaying of the prop sheet...
however, i cannot find the messages sent when a propertySheet is initializing its pages...

any one can help please ?

thanks in advance

Hi tox,

you must set the title of the property page before you come into the OnInitDialog(), e.g. on property sheet level, just before adding the page.

That way:

CPage5Dlg page5; // Prop page

page5.m_psp.dwFlags  |= PSP_USETITLE;	
page5.m_psp.pszTitle  = "Environment";

If you want to change the tab's text after the page is created, use CPropertySheet::GetTabControl() and then CTabCtrl::SetItem().
