The WM_SHOWWINDOW message is sent to a window when the window is about to be hidden or shown. There isn't a special message sent for the first show, so you'll have to keep a flag in the C++ class keeping track of whether WM_SHOWWINDOW has been sent before with wParam==TRUE.

I need some tips to debug my MFC app. When I close my application it (sometimes) still appears as a running app in the Task Manager. My app is quite big and I’ve not myself written all the code. Where should you start figuring out the problem? I’ve read a lot of Articles in this topic but I cant find any really good one for my problem.
Should I use any kind of Tool or… All tips are welcomed!

Often this is because your program creates one or more additional threads that were not shut down. They are still running, so your application is still in Task Manager, even though the main GUI thread has ended.

The strange is I'm not creating any new threads. I've figured if the reason is that I'm not properly closing down all dialogs (Created with CWnd::Create). Could that be the reason?

1) Check the permissions on the file
2) Make sure you're setting the cbSize variable:
blah.cbSize = sizeof(SHELLEXECUTEINFO);
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

How to convert char * to const char * ?
LPSTR s1;
LPCSTR s2;
s1 to s2
Thank you.
|
|
|
|
|
You don't have to. The conversion is done automatically.
|
|
|
|
|
LPSTR smenu;
GetMenuString(hmenu_options_thread1,uIDCheckItem,smenu,0,MF_BYCOMMAND);
MessageBox(hWnd, smenu,"Thong bao",MB_OK);
It appear an error, why is it ?
Thank you.

Buddy, you forget to provide memory to smenu.

Right code will be something like this
LPSTR smenu=NULL;
int nSize=GetMenuString(hmenu_options_thread1,uIDCheckItem,NULL,0,MF_BYCOMMAND);
smenu=new TCHAR[nSize+1];
GetMenuString(hmenu_options_thread1,uIDCheckItem,smenu,nSize,MF_BYCOMMAND);
MessageBox(hWnd, smenu,"Thong bao",MB_OK);
if(smenu)
{
delete []smenu;
smenu=NULL;
}

There is no real conversion!
char * and const char * are the same data types, but for the latter, there is only read-permission given by the compiler. When the software is compiled, there should be no difference at all!
So:
s2 = s1;
Don't try it, just do it!

when we double click a bat file, we see a DOS window, the program is command.com
my question is:
can we redirect standard output, error and input streams of command.com to my own app?
i.e. in my app, i use CreatePipe(...) for command.com and send command line to it to execute the coomad line then read responding from it to my app.
any links or hints for my question?
thanks

hi
i have the string as str1 and then concatenated in str2 and now i have to execute it
str1="\"c:\Program Files\Demo\xyz.dll\"" ;
str1="regsvr32.exe /u " + str1;
how can i execute this programatically.
Itried with ShellExecute and system but it does not work
waiting for reply
Best Regards

Try this
string sFile(_T("regsvr32"));
string sParam(_T("/u \"F:\\Data\\MAPIProp\\mapiprop.dll\""));
::ShellExecute(NULL,_T("open"),sFile.c_str(),sParam.c_str(),0,SW_SHOW);
|
|
|
|
|
u can find source code of regsvr32.exe in VC++ samples, which is just a few of lines.
add the few lines inside ur app, things will be much easier and better - then you do not need regsvr32.exe again.
