Hi,
1. Who creates Modal dialog box?. Is it created by the Connect method?
2. How you are sending the Cancel/Continue message to the STA thread? (I mean are you just using SendMessage/PostMessage). Use cannot use SendMessage and PostMessage on different thread. If you use, try PostThreadMessage).

Hi,
Thanks for the reply. Now for your queries,
The applications mainframe window creates a modal dialog in response to the menu action. The modal dialog is itself a thread. In the execute method of the thread it creates a connection to the remote server. Now if the connection is SSH I create another thread, this time a STA thread because I wanted to create the component on the thread itself,once the component is created successfully I proceed normally to actually open a connection.
Till the time the connection is created the user is displayed a modal dialog created earlier with a cancel button. If the user clicks on Cancel button I first issues a DisConnect call then use PostThreadMessage to send a WM_QUIT message to the thread that created a component and then wait for the thread to quit using MsgWaitForMultipleObjects API with an INFINITE time out specified, I am also pumping windows messages while waiting.
Hope this helps you to analyze the problem further.
Also please Note that it is difficult to change the current design as it is a legacy application
Thanks Again.

Respected all

I have a problem in VC i.e
after runing my program I loaded a list of "Bitmaps names" in a list box on a dialog box and then when i select one of these bitmaps the selected bitmaps has displayed which is in the oninit() function of MFC,but the previous window which have listbox of bitmaps has been closed and i want oth window visible to me, I did nothing for displaying bitmaps just use bitblt() function in onInitDialog() of MFC but the origional dialog box which has bitmaps list has been closed,and I want both window visible to me.
Plz guid me.

David,
--> bitblt() function in onInitDialog()
This is wrong method. You can't use bitblt in OnInitDialog() function. Because windows controls are displayed when WM_PAINT called.
I could not understand your child control became invisible. I think bitmap image could be overlapped. Just check that.
Please go for owner-drawn button controls. You can find a lot of samples for Owner-drawn controls..

Hi all,
In my project i have two DLLs(say DLL1 and DLL2).
DLL1 needs to access an array defined in DLL2.
I found many articles on Codeproject and other websites specifying sharing data among processes loading instances of a DLL.But here i have two separate DLLs.
IF anyone can help me with this.
Regards,
Lata

Is both DLL is load by same Process or different process...
#If Same Process ....
Easiesr method is already suggested By Mr. Gabriel...
#If different Process....
You have implement Interprocess Communication between them i.e. DLL

using system(), such as WinExec() is deprecated...

then him can use... CreateProcess(NULL, "C:\\Program Files\\MyApp", ...)
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );
// Start the child process.
if( !CreateProcess( NULL, // No module name (use command line).
"MyApp.exe", // Command line.
NULL, // Process handle not inheritable.
NULL, // Thread handle not inheritable.
FALSE, // Set handle inheritance to FALSE.
0, // No creation flags.
NULL, // Use parent's environment block.
NULL, // Use parent's starting directory.
&si, // Pointer to STARTUPINFO structure.
&pi ) // Pointer to PROCESS_INFORMATION structure.
)

::ShellExecute() is the function for you.
you could take a look at the MSDN[^] to see how it works

ShellExecute Api cannot be executed in Console Mode, you have to use system() function

2 possibilities :
1- you didn't read the link on the MSDN i gave you describing how ShellExecute() works
2- you didn't see you had to #include <shellapi.h>

yeah, i've seen your previous post.
actually, it depends if he has to execute his program in pure DOS mode, or if it will run under command windows in Win2000, XP, etc, where DOS don't exist anymore, and is emulated... it would work in the later cases...
