Re: CToolTipCtrl on key press?

I've managed to actually add tooltips to my controls now. Any ideas how i tie these to keyboard keypresses? I can't find any information on this.

There are inbuilt dialogs in MFC that do what I'm trying to achieve, but are added as a property on the resource. For example if you set a field to "Password: True" whenever you press Caps Lock within the field a tooltip (balloon style) appears at the caret position, rather than at the mouse position.

Thanks.

I have no idea what that means. what is an "inbuilt dialog"? And how do you add a dialog as a property?

Well a tooltip isn't magical, it's just a window, take a look at one in Spy++. You can make a window do anything you want including set it's position.

I wrote a c++ ATL dll, and now want to call it from another c++ app. What exactly do I need to do be able to call it?

In the h file for the ATL dll

STDMETHOD(MyFunction)(BSTR OutputDirectory, BSTR DlgTitle, BSTR BatchFileName, BSTR ResultsFileName, int ObjectStartNumber);

plus other functions

I tried to include this h file but got these errors:

error C2079: 'CSFilter' uses undefined class 'ATL_NO_VTABLE'
error C2239: unexpected token ':' following declaration of 'CSFilter'
error C2059: syntax error : 'public'
error C2448: '<unknown>' : function-style initializer appears to be a function definition
fatal error C1004: unexpected end of file found
Error executing cl.exe.

thanks,

~~CSFilter~~ Sorry, that is ATL_NO_VTABLE is undefined. You have not included the definition for it in your project.

I just took the .h file straight from my ATL dll project and did a #include in the test harness project.
What is it I need to do?

You need to configure your project to include any dependent header files and resolve any dependent library files to successfully compile and link.

Hi,
The output of the command line application 'netstat -n' will write to STDOUT, not STDERR. However you can redirect them both. Here is an example of how to achieve your goal.

Many thanks you all helped me on this thread
Everything seem that is difficulty

Let me describe again
Assume you create new Win32 Application project with select "a typical Hello Word ! application ". When you execute this project, system will show a window contain "Hello Word !" string.

I expect to replace string "Hello Word!" with value of cammand "netstat -n"

Example: replace "Hello Word !" with
"Proto Local Address Foreign Address State
TCP 127.0.0.1:1148 127.0.0.1:1149 ESTABLISHED
TCP 127.0.0.1:1149 127.0.0.1:1148 ESTABLISHED
TCP 127.0.0.1:1150 127.0.0.1:1151 ESTABLISHED"

many thanks

StartupInfo.cb = sizeof(STARTUPINFO);
StartupInfo.dwFlags = STARTF_USESHOWWINDOW;
StartupInfo.wShowWindow = SW_HIDE;

Args[0] = 0;

pEnvCMD = getenv("COMSPEC");

if(pEnvCMD){

strcpy(Args, pEnvCMD);
}
else{
strcpy(Args, pDefaultCMD);
}
