Yes, as always, Mike is correct. However, the CD is labeled (Windows 2003 Server). I am running VC 6.0 on XP and since I installed this PSDK I have problems with MFC assertions. In about 50% of the time when assertion fails XP gets into the act and wants to send "serious problem " message to MS and VC does not stop properly. Needless to say - it makes development harder.
Happy festivus to all.

Is there a simple way of checking to see if an external application, say Microsoft Word, is already running before creating a new process via CreateProcess? Thanks!
|
|
|
|
|
Yes.
You can use FindWindow command (win32 api).

FindWindow 
See EnumProcesses instead.

Thanks, that worked. I also have another question. I was planning on using AttachThreadInput() to bring the application to the front but I wasn't sure how to obtain the thread id. Any help is much appreciated. Thanks.

I'm using Visual Studio 2005. I'm trying to create a dynamic library for my MFC application. This library uses MFC via shared DLL and exports a class that contains functions using CString objects.
For example, I constructed a simplified library like so:
<code>#ifdef TEST_EXPORTS
#define TEST_API __declspec(dllexport)
#else
#define TEST_API __declspec(dllimport)
#endif
class TEST_API CTest {
public:
CString DoStuff()
{
return _T("This is only a test.");
}
};
Simple enough, right? But whenever I try to link my application to this library and use the CString-related function, I get linker errors like the following:
error LNK2019: unresolved external symbol "__declspec(dllimport) public: class ATL::CStringT<unsigned short,class ATL::StrTraitATL<unsigned short,class ATL::ChTraitsCRT<unsigned short> > > __thiscall CTestClass::DoStuff(void)" (__imp_?DoStuff@CTestClass@@QAE?AV?$CStringT@GV?$StrTraitATL@GV?$ChTraitsCRT@G@ATL@@@ATL@@@ATL@@XZ) referenced in function ....
I came across this article on Codeproject, wherein Nick Pirocanac recommends using CAtlString in the library instead of CString, but it was writen for Visual C++ 7, and it seemed to be addressing problems with ATL-based libraries and applications. I tried Nick's methods anyway, and they didn't seem to work.
I just recently migrated to Visual Studio 2005 from version 6, and of course this library worked just fine back then, before CString was template-ized. Now, the strange thing is that this problem doesn't seem to occur when I do a Release build. I scanned through the configurations, but I'm fairly new to VS8 and I couldn't find any difference between the configurations that would cause this.
Has anyone had similar problems, and more importantly, does anyone know how to fix this? I get the feeling it's something simple and obvious that will make me feel very stupid when it's explained, but I just have no clue right now. Any help would be most appreciated.

I was going through the project options again and I found the culprit. Apparently I had turned off the "recognize wchar_t as a native type" option at some point in my MFC application. And all this time I'd been thinking it was MFC's / ATL's fault. I'm such a dummy sometimes. :P

Not at all. You continued to work on the problem, and when you found the answer, posted the solution here. Others can then benefit.

For example:
1> I want to use the application C:\aaa\myzip.exe to open the file C:\abc\a.zip ；
2> I want to use the application that is automatically associated with the all .html files to directly open the file C:\abc\b.html ；
How to use CreateProcess to complete the two tasks above? Thanks!

1. Wrap your paths in quotes (not that you need it specifically for this example, but it's good practice for space-containing paths) and escape your slashes (or use the / method):
STARTUPINFO oStartupInfo;
PROCESS_INFORMATION oProcessInfo;
LPSTR szCmdLine = "\"C:\\aaa\\myzip.exe\" \"C:\\abc\\a.zip\"";
memset(&oStartupInfo, 0, sizeof(STARTUPINFO));
memset(&oProcessInfo, 0, sizeof(PROCESS_INFORMATION));
oStartupInfo.cb = sizeof(STARTUPINFO);
if (CreateProcess(NULL, szCmdLine, NULL, NULL, FALSE,
0, NULL, NULL, &oStartupInfo, &oProcessInfo))
{
WaitForSingleObject(oProcessInfo.hProcess, INFINITE);
CloseHandle(oProcessInfo.hProcess);
CloseHandle(oProcessInfo.hThread);
}
else
{
TRACE("Could not open the process. Error: %u\n", GetLastError());
}
2. Don't. Use the significantly easier method:
ShellExecute(NULL, "open", "file://C:\\abc\\b.html", NULL, NULL, SW_SHOWDEFAULT);

I've killed again, haven't I?

Hi to you all,
please help me. I'm looking for a method, to get fully access to a network-drive. It should be like it's done by the OpenFileDlg.
Thank's!

Can a C++ shell.DLL do a drop into an application that has drag-drop enabled? If yes, then does it make sense to search for the window handle to see if the app is running, if not start it with shell execute, then do the drop? Got any code or references somewhere?
Thanks,
DD

I have created a console application using straight WIN32 api in 'C'. When the user runs it I don't want it to show up...anywhere. Is there a way to specify that I don't want it to appear as a window?
I know you can do this with CreateProcess(), but I'm not spawning a process from another one. I'm running IT directly...?
For those wondering why the heck I want to do this; I'm writing a launcher application that, when a user clicks on a file with particular extension, this program will run (it will be registered with that filetype), figure out what version of our software to run, find it, then spawn the main application with the clicked on file as an argument. Then it will quit. So, we don't want to the user to see any of this "behind-the-scenes" work.
Thanks!

AFAIK console apps will always create the console. What I do when I want an app to run hidden the way you do is to create a windows app but do not create a window. Create a new win32 windows app, transfer all your code over to it renaming your main function to winmain. You also have to change the winmain parameters.

From the description of your needs, the launcher should be a GUI app, not a console app. The app can do all the work in WinMain() and never create any windows.

Thanks guys; this was the solution I was looking for. The other options showed the console window briefly; which was still undesirable. Thanks!

How about try this?
Q124103: "HOWTO: Obtain a Console Window Handle (HWND)"
and then in the main(), do a ShowWindow(SW_HIDE);
#include <windows.h>
#include <stdio.h>
HWND GetConsoleHwnd(void)
{
#define MY_BUFSIZE 1024 // Buffer size for console window titles.
HWND hwndFound; // This is what is returned to the caller.
char pszNewWindowTitle[MY_BUFSIZE]; // Contains fabricated
// WindowTitle.
char pszOldWindowTitle[MY_BUFSIZE]; // Contains original
// WindowTitle.
// Fetch current window title.
GetConsoleTitle(pszOldWindowTitle, MY_BUFSIZE);
// Format a "unique" NewWindowTitle.
wsprintf(pszNewWindowTitle,"%d/%d",
GetTickCount(),
GetCurrentProcessId());
// Change current window title.
SetConsoleTitle(pszNewWindowTitle);
// Ensure window title has been updated.
Sleep(40);
// Look for NewWindowTitle.
hwndFound=FindWindow(NULL, pszNewWindowTitle);
// Restore original window title.
SetConsoleTitle(pszOldWindowTitle);
return(hwndFound);
}
main()
{
ShowWindow(GetConsoleHwnd() , SW_HIDE);
while(1)
Sleep(10000);
}
