Hi,
This will sound very basic and silly!!!
but can someone help me out with finding out how to go about
doing a substr() in C++;
Thanks,
Brgds,
John

doing a substr() in C++;
You use CString.Mid() (this requires MFC), or
you use std::string.substr() (this is standardized and portable), or
us use strstr(), the plain old C-Library function.
Its up to you.

I want to somehow make my "About" box able to automatically write out the version of my program so I don't have to update it each time I make a new version.
How can this be done?
Something else

I guess u should follow
AfxGetResourceHandle then FindResource with lpType RT_VERSION then LoadResource then LoadString
Hope this help!

HGLOBAL hVersion = LoadResource(NULL, hVersionSrc);
void* pvVersion = LockResource (hVersion);
VS_FIXEDFILEINFO * pFfi;
UINT cbVerInfo;
VerQueryValue(pvVersion,"\\", (void **) &pFfi, &cbVerInfo);

Thank you all very much for the help
My "About" box is now automatically updated with the correct version number.

Is there any way I can create a a CIPAddressCtrl with a drop down history like a combo box? Or, a CComboBox control whose edit box acts like a CIPAddressCtrl?

Hi!
I was implementing the On-screen keyboard application that comes with Windows. I have two queries regarding this:
1. I have made my app 'always on top', but the problem is setting focus to the application just below this one. I am aware that SetFocus is useless in this case. I want to find a way to this using GetNextWindow
2. Let's assume notepad is going to be receiving keystrokes via this on-screen keyboard app. Can anyone send me code to this. I have tried something like:
DWORD dwProcessID;
::GetWindowThreadProcessId(hForeground,&dwProcessID);
::PostThreadMessage(dwProcessID, WM_KEYDOWN, 65, 1);
::PostThreadMessage(dwProcessID,WM_CHAR, 65,1);
::PostThreadMessage(dwProcessID, WM_KEYUP, 65,1);
But this doesnt help.
Any help will be greatly appreciated.
Thanks for your time
Richard

Better to use FindWindow or FindWindowEx and SendMessage or PostMessage

For Win32 applications, not MFC
thanks all!
|
|
|
|
|
The majority of the articles on CodeProject for sockets programming use the Win32 Sockets functions rather than hte MFC CSocket & CAsyncSocket, its only the user-interface that is built in MFC usually. So you can grab most of the socks code and build your win32 app around what you can pick up.

Dear All,
Good Day ALL,
I have a problem in a program am working on, am using an OCX from microsoft in a MFC program this OCX is "Microsoft form 2.0 Label" the problem is when i run the program on my machine Background color of the label is the same as the BackGround color of the Main Form which is correct;But when i run it on Different Machine the Background color changes from Main Form Color plz help me how can i correct this.
Thank you all for help.
Best Regards,
Mohammad Zakarni

In the properties of the control, set the background color to:
-2147483633
(it'll change it to hex for you)
or you can do it via code:
CLabelControl* l = &this->m_yourLabel;
l->SetBackColor((long)GetSysColor(COLOR_3DFACE));

Hi,
I am working on a program in which multiple controls use the system image list. My code looks like this:
<br />
SHFILEINFO sfi;<br />
HIMAGELIST hSystemImageList = (HIMAGELIST) SHGetFileInfo("a.txt", 0, &sfi, sizeof(SHFILEINFO),<br />
SHGFI_SYSICONINDEX | SHGFI_SMALLICON);<br />
m_control1.Attach(hSystemImageList);<br />
m_control2.Attach(hSystemImageList);<br />
Attaching the first control to the system image list works ok. Attaching the second control results in a crash. Debugging points to the system image list attach.
Does anyone know what the problem is and how to solve it?
Thanks,
Woody
