Hi Member 10296418, to avoid the exception you need to close the Socket Connection and reopen the same. you can create multiple virtual ports and try creating multiple threads for the socket connection. And also give 5MS delay after closing the connection. Hope this helps . Regards, Shyam Kodase Feb 13 2014 ;)

Hi, Thanks for your reply. Hmm.. I have just shared the folder( permission to everyone i think). The problem is still exists when UAC is enabled( my UAC settings is default) and I run application as admin. Its works fine when UAC is disabled( i.e Never notify). Thanks Arun

Or.... just completely separate your GUI from your working code. :)

I found a simple workaround using FindWindow() and SetForegroundWindow to force the Excel window to the foreground. Note, the application parameter of FindWindow() needs to be "XLMAIN". HWND xlsHWnd = FindWindow(_T("XLMAIN"), NULL); SetForegroundWindow(xlsHWnd);

Fasten your seat belt and read this article: "Loading a DLL from memory"[^]. Veni, vidi, vici.

Thank u very much my dear friend really appreciate your help.

You could create a custom resource inside the exe, and then read it at runtime. Check out: Creating a Resource[^] The difficult we do right away... ...the impossible takes slightly longer.

I've actually done this a few times in my life, it's not any more difficult than having an API for two pieces of software to communicate across. Usually on the hardware side, they'll implement a regular ethernet stack so they follow all the same rules and guidelines that you do on the PC software side. As a matter of fact, most people usually buy an Ethernet "core" that gives them the functionality without implementing it themselves, same as you using the Winsock library. The only trick is really understanding the bytes received and what they mean (just an exercise in arranging structures and casting bytes).

David, Adding the line: cout << setiosflags(ios::fixed); before the for loop did the trick. The program now works as expected. I am happy. I thank you and all the other people who responded to my post for their help in this matter. Bob

Please clarify... when you say "I just tried the above code and it works fine.", do you mean you put the code fragment that I printed, in another program and ran it? I was hoping you downloaded and built my sample code... I guess that would be a problem if you don't use MinGW. I agree that it is something in my code, but I'm damned if I can figure out what !! I'm comparing the stripped-down failing code against another working Win32 utility that I have (where the button code works fine), and for the life of me I cannot figure out what the difference is!! What I'm doing now, is I made a copy of the working project, and am pasting pieces of my target project into it, one piece at a time, until I hopefully find what breaks the color dialog. My great fear is that I'll never find it, and the copied project will work fine - and I'll NEVER figure out why this one is broken... :wtf: //************************ Later note: yeah, I got the application completely ported over from the original project to the new project based on a dialog where the ChooseColor() worked properly, and the entire project works fine. Of course, I can't find any difference between the two, that could explain the original problem. I guess I'll never know...

LPCTSTR data = L"0\0"; LONG setRes = RegSetValueEx (hKey, value, 0, REG_DWORD, (LPBYTE)data, 1); You are storing a Unicode string instead of an integer. The data should be a DWORD containing either 0 or 1, like: DWORD data = 0; LONG setRes = RegSetValueEx (hKey, value, 0, REG_DWORD, (LPBYTE)&data, sizeof data); Veni, vidi, abiit domum

When adding the command to the DSP file, the place should not care as long as the command is correct. But the VC 6 project settings should provide an input field for user defined linker options where you can enter the option (with more recent VC versions it is 'Additional Options' on the Linker - Command Line tab).

I have changed my directory structure and separated the common "applications" from the project. That way each project can access the common application, likes SDK for example, using direct path. Thanks for all suggestions, it helped to reinforce the KISS motto.

Hi, The Microsoft API for this is Windows Automation API[^]. It is built on top of Microsoft Active Accessibility[^]. Expand the nodes on the left frame and you might find some sample code. Best Wishes, -David Delaune

Well it depends on your definition of a matrix of strings. Do you mean a 2-dimensional array of string ponters or something more complex? Veni, vidi, abiit domum
